Central America is the site of contending crustal plates–notably the Cocos Plate in the Pacific Ocean which is being subducted beneath the Caribbean Plate right off the western coast of central america at a rate of 72-81 mm/yr.  It’s this area where the Central America Volcanic Arc exists which forms the volcanoes of Guatemala, El Salvador, Nicaragua, and Costa Rica.  To the north there is the North America Plate which is moving to the west at about 20 mm per year resultng in further seismic turmoil.  Then to the east the North American plates dives beneath the Caribbean plate as does the South American plate to the south.

     Once the link between North and South America was established there was a great influx of North American fauna into South America and vice versa to  a lesser extent.  The great marsupial fauna of South America died off mostly as did other less successful groups.  Some of the South American biota moved into North America.  Central America remains today one of the most biologically diverse areas in the world.

    Costa Rica and the rest of the isthmus has acted as a filter bridge in this great migratory process that really picked up steam only three million years ago when the connection was complete between North and South America.  The diverse topography of Costa Rica has resulted in refugia where species could still live after dying out in other areas.  This combined with the species from the north and from the south has resulted in a tremendous amount of biotic diversity in this small area.

    It is estimated that in this small country there are 500,000 to 1,000,000 species of plants and animals with most remaining unknown.  Insects by themselves make up about half of this diversity, whereas 850 species of birds can be found–about ten percent of all known species of birds.  North America has about half that number.  Others estimate about 160 species of amphibians, 220 species of reptiles and about 10% of all known butterflies.

   And all this in the second smallest Central American Nation (El Salvador is the smallest).  Only 119 km across at the narrowest point in the south and 280 km wide at its broadest point, it is quite easy to drive across the country in about five hours.  Solely in the tropical latitudes it still exhibits a broad range of distinct climate zones (12). 

The eastern Caribbean side is the wetest whereas the western pacific slopes are the driest.  Most areas have a rainy season, or “green season,”  (May-November) and a dry season (December-April) with the rainfall almost everywhere following a predictable schedule.  Usually the highland ridges are wet with the windward sides being the wettest.

It was 3 am and my bleary eyes found it  hard to see through the beating of my windshield wipers, but the tiny object in my headlights appeared to be something other than a small twig.  As I got out of the car and picked it up, I realized it was a salamander quite different than the typical Rough Skin Newt (Taricha granulosa) that I usually found in this area.

Although I handled it with great care, when I placed it into a container to hold it until the next day, I found that in its exertions to escape, it had lost its tail which was squirming distractedly about.  It also appeared quite motionless, and I wondered whether it was dead or whether it was simply feigning death.  After handling it, I noticed a dried secretion on my hand which I was careful to wash off since such secretions can often be irritating to mucous membranes.

    The next morning I found it to be quite chipper despite its moribund state the night before, and I confirmed that it was the lungless salamander, Ensatina eschscholtzii, which occurs from British Columbia to Baja California, Mexico.  This was the second specimen that I found crossing the same street in two months (April and May, 2012)–both times in a light rain around 3 am.

    These little salamanders have no larval stage and lay their eggs mostly in April and May under logs, and bark, and inside animal burrows, etc. and are usually attended by the female.  The clutch size ranges most commonly from 9-16 with a range of about 3-25 eggs.  The time it takes for the eggs to hatch varies amongst the subspecies, ranging from 113-142 days with a maximum of 177 days (Monterrey salamander).  The time involved was usually inversely proportional to egg size.

    The young reach maturity in three to four years with males reaching sexual maturity at about 48-55 mm snout/vent length while females reach maurity when they are over 60 mm snout/vent length.  One researcher (Stebbins) estimated that the oldest animals he studied was greater 8.5 years old while another researcher estimated ages up to 15 years.

Although quite variable in its coloration, it typically has nasolabial grooves, about 12-13 coastal grooves along its side, a constricted tail which can often snap off to distract predators, and light coloration at the base of its legs.

      I keep getting these different types of fish confused.  I was checking out their differences and characteristics and thought that I would summarize what I found here.

Goldfish:  Apparently goldfish were bred in China over a thousand years ago for their colors  from the Prussian Carp (Carassius gibelio gibelio once  

called  Carassius auratus gibelio) originally an Asian species, but now also spread throughout Europe. (Photos from Wikipedia)

Koi (which means carp in Japanese): These colorful fish have been bred from the common carp  (Cyprinus carpio). Photo from Wikipedia

 The common carp was raised as food in Rome as long ago as 2,000 yrs ago and was cultured in China at least by the fifth century.  Apparently mitochondrial DNA studies have shown that the Koi has been bred from both the western eurasian subspecies of the common carp (Cyprinus carpio carpio) and the east asian subspecies (Cyprinus carpio haematopterus).  This multilineage background is still confused. The common carp is widespread throughout Eurasia and the United States.

Other Common Asian Carp Introduced into the United States:

• grass carp (Ctenopharyngodon idella)
• silver carp (Hypophthalmichthys molitrix)
• bighead carp (Hypophthalmichthys nobilis)
• black carp (Mylopharyngodon piceus)

Grass, silver, bighead and black carp are  sometimes known as the “Four Domesticated Fish” in China and are the most important freshwater fish species for food and traditional Chinese medicine. Bighead and silver carp are the most important fish, worldwide, in terms of total aquaculture production.

Silver carp or Jumping Carp (they have no stomachs and filter feed almost constantly) are the fish that I have often seen on television jumping high out of the water when frightened by motor boats.  These fish can jump 8 to 10 feet into the air and often cause injuries to boaters. When you consider that Silver carp can grow up to 100 pounds, you can see how dangerous they can be to boaters.  Bighead  carp normally don’t jump when frightened.photo from Wikipedia

Bighead, silver, and grass carp are known to be well-established in the Mississippi River basin (including tributaries) of the United States, where they at times reach extremely high abundances, especially in the case of the bighead and silver carp.

Bighead and silver carp feed by filtering plankton from the water which because of their abundance has led to concern because of possible competition with native species (filter feeders such as the paddlefish, shad, etc.). Of course because of the fact that these fish are filter feeders, they are difficult to catch by normal means.

Silver Carp’s head does not have scales and the body is covered in very small scales.  The eyes are turned forward and appear to be looking down a little.  The mouth is turned up.  The body is somewhat flattened from side to side and usually has olive-green backs and silvery sides sometimes with a bronze to reddish tinge.

ANNA’S HUMMINGBIRD A male Anna’s Hummingbird showing his bright, irridescent gorget.  This color is not contained in any pigment in the feathers, but is caused by the refraction of the light which is caused by the physical structure of the feathers.

ANNA’S HUMMINGBIRD  A side view of the same Anna’s Hummingbird. The gorget on his chin appears black now as the angle of the light changes and is no longer refracted.

       While leaping along some volcanic rocks on a Pacific beach in Guanacaste province in Costa Rica, I dropped my camera into a tide pool.    It was only underwater for a second before I snatched it out.  I immediately dried it with my bandana, took the lens off and opened the battery compartment, looked inside and saw it was all dry.  Apparently some water got in,  possibly through the control knobs and buttons, because it wouldn’t work.  It appeared that everything turned on fine, but the release switch to take the photograph wouldn’t work.

     After investigating I found that to clean and possibly repair the camera would cost more than I was willing to pay (especially since such cameras could not always be repaired, but you would have to pay to find out), so I decided to get another camera along with a lens which I have had my eye on for a long time.  This lens was the Nikkor 18-200mm lens with vibration reduction which allows the shooter to take photos at lower speeds.  Of course with telephoto lens this vibration reduction (VR) would especially come in handy.  The lack of some sort of telephoto lens on the Costa Rica trip was frustrating since other people were getting great bird shots with their telephotos, whereas I had to be satisfied with my 18-55 mm!  Some people have accused me of dunking my camera into the salt water so I would have the excuse of getting a new camera.  I totally deny this…at least it wasn’t a conscious action.

    Anyway I have found that for the first time, I am able to take half-way decent photos of birds.  I say for the first time although back in the early seventies I had a cheap Spiratone 400mm lens ($34!) which was half the length of my arm and which you had to manually stop down after focusing with the lens wide open.  It didn’t have a vibration reduction mode incorporated in the lens of course, and the photos I took were usually blurry.

   This past Thursday I went down to the local park by the waters of Puget Sound where this little male Anna’s Hummingbird has been hanging about for the past 3 or 4 years and was able to take these shots shown above.  You can check this site for more.  The little male would turn his head back and forth which would cause his brilliant gorget to flash on and off like a neon light as the light angle varied.  This is the same fella whose “chirping” displays I talked about before.

Central America is the site of contending crustal plates–notably the Cocos Plate in the Pacific Ocean which is being subducted beneath the Caribbean Plate right off the western coast of central america at a rate of 72-81 mm/yr.  It’s this area where the Central   America Volcanic Arc exists which forms the volcanoes of Guatemala, El Salvador, Nicaragua, and Costa Rica (See photo above of Volcan Arenal).  To the north there is the North America Plate which is moving to the west at about 20 mm per year resultng in further seismic turmoil.  Then to the east the North American plates dives beneath the Caribbean plate as does the South American plate to the south.

     South America was part of the great southern land mass, Gonwanaland.  When it drifted away from the rest of the southern continents it remained in relative isolation for over sixty million years.  Once the link between North and South America was established there was a great influx of North American fauna into South America and vice versa to  a lesser extent.  The great marsupial fauna of South America died off mostly as did other less successful groups.  Some of the South American biota moved into North America.  Central America remains today one of the most biologically diverse areas in the world.

    Costa Rica and the rest of the isthmus has acted as a filter bridge in this great migratory process that really picked up steam only three million years ago when the connection was complete between North and South America.  The diverse topography of Costa Rica has resulted in refugia where species could still live after dying out in other areas.  This combined with the species from the north and from the south has resulted in a tremendous amount of biotic diversity in this small area.

The eastern Caribbean side is the wettest whereas the western pacific slopes are the driest. When I visited the Pacific coast area of Costa Rica (Guanacaste), the hills and countryside was covered with trees devoid of leaves.  It was strange seeing black howler monkeys sitting in leafless trees.  This was in sharp contrast to the rainforest on the Caribbean coast.   Most areas have a rainy season, or “green season,”  (May-November) and a dry season (December-April) with the rainfall almost everywhere following a predictable schedule.  Usually the highland ridges are wet with the windward sides being the wettest.

This is Concepcion, a volcano,  forming part of an island (Ometepe)  in the middle of Lake Nicarauga. It was putting forth steam and smoke just as our plane flew over. There was a heavier cloud of material that you can just see on the other side of the volcano which was proceeding down the NW slope towards the small communities just seen on the margin of the island.  This sort of thing must be common, because right at this time the pilot announced that we were beginning our descent into San Jose, Costa Rica without even mentioning that there was an erupting volcano just below us!   The last eruption is said to have occurred last December with gas and ash rising 150 meters into the air.  Maybe the above photo doesn’t depict an eruption?  Hmm…looks like it goes at least 150 meters into the air.  Addendum:  I just found this site which I quote:

“On 8 March [just when we were passing over!] an ash and gas plume from Concepción rose to 2,100 metres altitude and light ashfall was reported in nearby communities. Low levels of seismic activity and occasional small explosions producing light ashfall were reported during subsequent days. On 12 March Washington VAAC issued a volcanic ash advisory reporting an eruption producing an ash cloud that reached FL100 (10,000 feet / 3,000 metres altitude). According to news reports there were two further explosions on 14 March. No casualties or damage resulted, although civil defence alerts remained in place for communities around the volcano. The Nicaraguan geological service INETER described the volcano on 19 March as ‘practically in a full eruptive phase’, with 34 explosions between 18:00 on 17 March and 11:45 on 18 March. On 19 March it was reported that the Nicaraguan government was sending army and navy units to the area around Concepción to strengthen civil defence preparations and prepare evacuation routes, ‘just in case’. The location of Concepción, on the island of Ometepe in Lake Nicaragua, makes floods and tsunamis a potential danger if the volcano were to erupt.

However, shortly afterwards activity at the volcano began to decline, with INETER reporting on 22 March that degassing and seismic activity had fallen to low levels in comparison with the preceding days. On 24 March INETER confirmed a ‘considerable reduction in activity’ but reported continuing ‘anomalous’ levels of seismicity. The current situation is that activity remains low, but the volcano continues to be carefully monitored.”

   My father returned home from the hospital today!  He had open heart surgery last Monday (Jan 25) which went very well.  I guess they said that he could have gone home yesterday (Friday), but he said he wasn’t ready to leave yet!  Four days seems like a very short stay after such major surgery, but I guess that is the norm now if the patient is doing well.  He was in ICU until Wednesday.  He is at my sister’s place where he will stay for about the next two weeks as he recovers.  I sincerely thank everybody for their prayers and good wishes.

     Needless to say I am very relieved and overjoyed that he is doing so well.  He has never had any sort of major illness, no surgery, and as a child, I can’t remember him ever being sick.   His experience which seemed to come out of the blue with no warning (good cholesterol levels, blood pressure about 120/70, etc) makes me much more determined to live the sort of lifestyle that precludes such problems–exercise, proper diet, etc.

     Last Thursday (Jan 21)  my father had some chest pain after returning from the store.  It wouldn’t go away,  and soon my father realized that this wasn’t the normal discomfort that he sometimes felt from the acid reflux which he sometimes has.  Then he did something out of character–he asked his next door neighbor to call an ambulance.

    I understand how out of character this was for him, because I am just like my father in many ways.  We both would tend to ignore pain until it became overwhelming, and for him to ask for an ambulance shows that it was something out of the ordinary.   I am still surprised that he did this and didn’t try to drive to the emergency room by himself.  It just goes to show that he was experiencing something out of the ordinary and that he is much smarter than I am.

     The next morning he had an angiogram and instead of a stent which they thought he might need, they found he had two coronary arteries which showed some blockage.  He would need double bypass surgery.  The interesting thing is that they found that his EKG was normal.  A slight elevation of heart enzymes showed that he had a mild heart attack also.

    My father will be 86 in March and has always been extremely healthy.  The doctor, one of the best in the Dallas area, said that he doesn’t consider the patient’s age in considerating this procedure, but their health, and that my father was otherwise in excellent health.

     The operation will take place at 7:15 am CST tomorrow.  I’d appreciate any kind thoughts or prayers sent my father’s way.

     It is Christmas Eve, 11:55 pm, and I am alone at work, getting ready to go out into the frosty night.  Once again I think back on past times with my family as I have many times before.  I haven’t posted much lately because I have been working so many long hours, but soon it will be all back to normal.  Merry Christmas to All!

      I was wondering why people were staring at me at the Mississippi visitor’s center last summer after I had pulled off Interstate 10.  I checked my zipper, nope…wiped my nose, nope nothing there, then I realized that I was wearing two pairs of glasses, one low down on my nose and the other right above it. 

       I have always had excellent eyesight, never needing glasses…until a few years back.  More than a few years actually.  Presbyopia is an ailment that inflicts many people as the lens of the eye looses its flexibility and can no longer accomodate close vision.   When this condition got to the point that I could ignore it no longer, I bought two expensive pairs of glasses.  “Over a hundred dollars for the frames?” I almost shouted in disbelief to the clerk.  “I can get a pair of sunglasses for a few dollars that has perfectly good frames!”

     “Oh no!,” she said, horrified, “these glasses are much finer, much lighter and stronger.”  So I ended up spending several hundred dollars for two pairs of glasses.  Years later I realize that…I was absolutely right, and was foolish to have bought such thin frames that snapped the first time any pressure was put upon them, and I never did get used to the bifocals.

     Now I get my glasses at a place that has satisfied my needs in many ways, and I have never had second thoughts about the glasses that I buy there—the Dollar Tree.  I buy glasses for close work for one dollar with a diopter value of about 2.5.  I also found that recently I have problems seeing far away–especially when driving at night, and I found that these one dollar glasses with a diopter of about 1.25 are great for seeing far away.  I even found some sunglasses with a diopter value of 1.25 which are great on sunny days.  These glasses work wonderfully well and are durable.  I have some that I’ve had for years, and I usually never have any problems with them unless I sit on them.

      So that day as I was driving down I-10 I was wearing my “far away glasses” (1.25) and doing perfectly fine until I needed to look down at the speedometer or something else on the dash board like the radio controls, and then I needed my “close up” (2.5) glasses.  Both were hanging about my neck by cords, and I found that by placing the close up glasses low on my nose and my far away glasses up higher on my nose, I could switch back and forth with no problems.  However, I had neglected to pull one off my nose when I went into the visitor’s center.  

        I found that method works very well, but I haven’t quite overcome the attention I get when I do it, so I usually only do it at home.  However, I have left the diopter labels on the lenses in order to tell the glasses apart, and I always get comments such as:  “You still have the label on your glasses.”  “I know,” I reply,  “And I still have the label on this one,” pointing to the other one hanging about my neck.

When I reached the beach on my walk two Sundays ago, I saw a large black body out in the water, then a great fin protruding above the surface.  At first I was confused as to what I was seeing,  then everything clicked into place, and I realized that I was watching a pod of Orca or Killer Whales coursing north through the narrows of Puget Sound.  I immediately began shouting with excitement.  Not only was this the first time that I had ever seen these magnificent creatures, but they are rarely seen this far south in the sound.  They had just passed the park which I was in and were taking their time on their way north, their backs and fins protruding above the water.  I stood there watching them until they disappeared.  Then I realized that I had been the only one shouting, but I felt blessed and full of energy.

The Killer Whale got its name from the fact that it often was observed eating whales, but there are at least three different groups or Orcas which seem to have specialized in either fish and squid eating, and those which eat almost exclusively marine mammals.  I was tremendously excited after seeing the Orcas pass, and while musing on them I was curiously reminded of the end of the universe.

I was reminded of the death of the universe by the fact that Killer Whales occupy the top of their food chain, and thus their numbers and biomass are severely limited by the Second Law of Thermodynamics which basically says that energy tends to go from ordered states to disordered states, and during any transfer of energy some energy is lost to the system (converted to heat).  Thus every time a cow eats its supper (plants) roughly 90% of the energy in the plants is converted to heat and lost to the system (ecosystem in this case).  So consider the following marine food chain scenario:

phytoplankton (100%)—->zooplankton(10%)—->small fish(1%)—->larger fish(.1%)—->seals(.01%)—–>Killer Whales(.001%)

Suppose the phytoplankton by means of photosynthesis captures a certain amount of energy from the sun.  We’ll say this amount of energy is 100%.  This represents what we start out with in this food chain.  The zooplankton (small floating animals) eat the phytoplankton, but about 90% of the available energy is lost, so the zooplankton only ends up with 10% of what we started with.  Then the small fish eat the zooplankton and the same thing happens, 90% is lost and the small fish end up with 1% of the original amount.  And so on…until we end up with the Killer Whales which in this example will end up with only 1/100,000 of what we started with–all due primarily to the Second Law of Thermodynamics!   Not much energy is available to the top predators in food chains.

Or consider this alternate food chain:

phytoplankton (100%)—->zooplankton(10%)—->Great Blue Whales (1%)

The Great Blue Whales by eating much lower on the food chain (zooplankton: krill mostly), theoretically has 1% of the energy with which we started–a thousand times more potential energy than is available for the Killer Whales!  So theoretically the biomass of Great Blue Whales could be as much as the total biomass for the small fish in the first food chain…just concentrated in much bigger bodies, potentially much more biomass than in the Killer whales.  Two strategies exist in this case:  by eating at this level in this food chain, you can be small and extremely numerous or large and much less numerous–the biomass should be about the same.  I think there is a lesson here as the human population density soars above 6 billion people.  Can we continue to eat high on the food chain?

So why did all this make me ponder the end of the universe?  Because if energy continues to go from concentrated sources of energy to less concentrated sources (entropy), then eventually the universe will run down.  All the stars  and other energy systems will have dissipated their energy into heat, there will be no more people, spiders, planets, stars…nothing but a universe in which the energy is evenly distributed–the Heat Death of the Universe.

I was reading the paper today, and when I got to the funny papers (comics), I found an odd thing.  I kept seeing the same references to volunteerism and community service in many of the strips.  Below is a summary of what I found:

1. Garfield: “Today I volunteered to help clean up the city park.”
2. The Born Loser: girl volunteered to rake leaves for the born loser who had hurt his arm.
3. Stone Soup: woman building houses for charity in Thailand.  (I hate this strip and never read it…did this time for the survey).
4. Pickles: The old lady volunteered to read to schoolchildren.
5. Luann: A service “team” started at high school “Woohoo! Volunteers rule!”
6. Baby Blues: Children volunteered for too many projects.  “Ok, I got everything straightened out with your service coach.”
7. Pooch Cafe: Pooch volunteered to visit sick kid in hospital.
8. Dennis the Menace.  Dennis volunteered to wash the Wilson’s windows.  Sign read: “Volunteer to help others.”
9. Blondie:  Dagwood volunteered to help with a senior citizens’ project.
10. The Family Circus:  Kids helping out in the kitchen.  “Hi, Mommy!  Can I volunteer to be some ‘nother help?”
11. Marmuduke: He starts a homeless shelter for dogs in the house.

Eleven out of 22 comic strips dealt with volunteerism–50%!  “Ok,” I thought, “obviously it must be Volunteer Week or something like that.”  But no,  Volunteer Week was April 19-25.  What the heck is going on?  It must be something that has been in the news or perhaps being pushed by somebody…but for the life of me I have no idea what.  I have noticed this happening before–the comics suddenly dealing with a particular subject.

Ok, I just googled some more and may have found what is going on: “18 October: The media blitz has arrived.  As we reported, in June, the Entertainment Industry Foundation (EIF) announced a commitment to incorporate volunteering and service into both news programming and ongoing fictional television series beginning the week of October 19.   EIF has branded this effort as “iParticipate” and opened a Web site at www.iparticipate.org.  There you can learn about the initiative, keep up with a blog about it, and view video clips of celebrities answering the question, “how do you serve?”” http://www.energizeinc.com/news.html

Ok…it’s some sort of media blitz by the Entertainment Industry Foundation.  I guess it even involves the funny papers.  How does this work?  Do the comic strip writers receive their subject du jour from somebody, and they dutifully accomodate their strips to  promulgate the subject?

Why am I not thrilled?   Volunteerism is a good cause isn’t it?  And the media has been influencing us for years to buy products, etc.  Brainwashing for a good cause is good isn’t it?  Why does this leave a bad taste in my mouth?  (making mental note of those strips who participated and those who didn’t)

   The Grey Wolf (Canis lupus), almost hunted to near extinction in the lower forty-eight states, once again can be legally killed.  This has come about after the U.S. Fish and Wildlife Service took the wolf off the endangered species list last May and will allow Idaho and Montana to reduce the wolf population down to 150 per state.  This will allow about two thirds of the area’s wolves to be killed.  Over 11,000 tags  ($11.75 apiece) have been sold, but Tony McDermott, fish and game commisioner of the Panhandle area, estimated as many as 70,000 might be sold.  As of now two wolves have been killed today. 

     Listening to the reports on the radio and reading the accounts concerning this issue, I was struck by the vehemence exhibited by the hunters.  It was if they were on a holy mission.  Here are some of their remarks:

1.  Wolves kill elk wantonly and leave the meat to rot.  They are depleting the elk and deer herds. 

2.   Apparently some of these intense feelings against the wolves originate in fear.  Some fear that they need to be protected against a predator:  ”They’re running down the middle of the road in Lowman in the winter.”  Others indicate that now they won’t have to worry about their kids at the bus stop, or their pets, and that now they can go for a walk without carrying a gun.   

Are wolves really as dangerous as these people claim?  Are their fears justified?  Here’s the conclusion of two studies:

“The Linnell and McNay reports show that wolf attacks on people are very rare. The records they examined indicate that wolves have wounded and killed several hundreds of people, but given these attacks were over a period of centuries and throughout the northern hemisphere, wolf attacks are sparse and meagre. Only 17 cases of people killed by wolves were found in the last 50 or so years in the whole of North America, Europe and Russia - 17 people in a human population of roughly a billion people.”

Here is another person’s perspective commenting on these reports: 

“See this in perspective. About fifteen people are killed on average per year in horse riding accidents in England and Wales alone (Office for National Statistics). Horses are more dangerous than wolves.

Again, almost all the wolves in the US outside Alaska live in Minnesota. These 2,500 wolves have killed no one. Yet one or two people are killed each year in that state by the rarity of lightning strike (NOAA). Lightning is more dangerous than wolves.”   The writer goes on to claim that live stock depredation is greatly exaggerated, and that wolves can often live close to people with few problems.

Here is a conservationist’s viewpoint:

“The scheduled wolf hunts would cripple the regional wolf population by isolating wolves into disconnected subgroups incapable of genetic or ecological sustainability. The wolf hunts would also allow the killing of the breeding alpha male and female wolves, thereby disrupting the social group, leaving pups more vulnerable.”

No other endangered species has ever been delisted at such a low population level and then immediately hunted to even lower unsustainable levels.

The decision to hunt wolves comes as Yellowstone National Park wolves declined by 27 percent last year – one of the largest declines reported since wolves were reintroduced to Yellowstone in 1995. The northern Rockies wolf population also has not achieved a level of connectivity between the greater Yellowstone, central Idaho, and northwest Montana areas that is essential to wolves’ long-term survival.

Wolves are still under federal protection in Wyoming because a federal court previously ruled that Wyoming’s hostile wolf-management scheme leaves wolves in “serious jeopardy.” The Fish and Wildlife Service in the recent past held that a state-by-state approach to delisting wolves was not permitted under the Endangered Species Act, but the federal government flip flopped on its earlier position and this year took wolves in Idaho and Montana off the endangered species list while leaving those in Wyoming on the list.

In addition to Wyoming, the states of Idaho and Montana have refused to make enforceable commitments to maintain viable wolf populations within their borders.”

Lots of hysterical claims have been made by those advocating the wolf hunts.  Personally I believe that they need to present more hard data to support their claims.

    I was recently watching this TV program on black holes.  As usual when I contemplate such things, I became slightly depressed.

    When a star which is about three times or more the mass of our sun reaches the end of its life, it collapses and in the process blows out a great mass of matter and energy creating a supernova.  What is left behind is so incredibly dense that the gravitational field that it creates traps even light itself from escaping—the black hole.

     Black holes come in many sizes.  Sometimes they coalesce, creating even larger black holes.  The evidence is pretty conclusive that the center of most galaxies is occupied by massive black holes.

    The program showed computer simulations of galactic collisons and close encounters that spanned eons (see here for some simulations).  The billions of stars in each galaxy in these simulations resembled dust motes that swirled and rotated about each other creating fantastic shapes before settling down to some sort of stable configuration.  Here is one interesting quote concerning the movement of galaxies:

It is speculated that a feeding frenzy occurs when large galaxies collide resulting in even more massive black holes.   It is believed that hundreds of thousands of smaller stellar black holes swarm about the massive galactic black hole subjecting the nearby star systems to a destruction derby which causes some stars to leave the galaxy entirely or causes it to fall into the massive center.

     Although our own Milky Way Galaxy has probably not consumed any large galaxies (smaller ones, yes :burp:), in about two billion years, Andromeda, our nearest large galaxy, and ours will begin to collide.  The massive black holes of each galaxy will coalesce to form one large super black hole that will consume incredible amounts of matter, igniting a new quasar.

   Now the thought of all this is totally fascinating in some respects.  The idea of billions of galaxies  inexorably following the laws of physics…matter and energy interacting in such spectacular ways fascinates and enthralls one’s imagination.

   But then my imagination swerves off on a tangent.  I think of the crowded galactic center, probably having large numbers of older stars than what is found out near the rim.  Many of these older solar systems very likely have life forms on their planets.  A certain small percentage, amounting to thousands when we consider these large numbers, very possibly supports intelligent life forms.

    I think of these intelligent beings contemplating their fate, watching their own star system begin it’s inexorable slide toward the maw of the great ravening beast at the galactic center.  I think of the panic, the frantic plans to save the race, possibly sending out colony ships.  I think of those left behind perhaps having the time to develop a philosophy of resignation to prepare themselves for the inevitible end. 

    I think of this happening thousands of times over the millions and billions of years that is involved in the process.   I think of these civilizations, unique in their outlook and philosophies…lost forever.

     And if this isn’t bad enough, I think of the implications.  I think of sentient beings living on  infitesimal motes of dust, coming into being, surviving and ultimately wending their way to extinction in a blind, uncaring universe of interacting energy and matter.

      Sometimes this is disturbing when I ponder upon it.  

     Then I begin to think of the relative nature of it all.  The life of man compared to the 14 billion year age of our universe, the almost four billion years that have passed since the origins of life on earth, the gradual evolution of life eventually resulting in me pondering such things.  

     And then moments like this morning as I walked through fog and mist, my face upturned, feeling the cool droplets on my face, listening to the foghorns and the sound of small birds in the forest through which I passed. 

     Perhaps we create our own caring, our own warm little niche in this universal howling wilderness.

    Thank the good Lord for  small things, I think…to heck with the long view.

     I am reading The Drawing of the Dark by Tim Powers for the second time and have been struck again by just how much I like and admire his novels.   I have read and re-read his books since discovering them years ago, and they never fail to entertain and enthrall me.

      Every time that I read one of his books I am tempted to sit down and devour it as soon as possible, but I try to strictly limit myself.  I try to stretch it out as long as possible, like a wonderful meal, savoring every aspect of it.  Anything really good in my opinion is worth taking one’s time with–and Tim Power’s books are very, very good.

     His books could be labeled fantasy I suppose, or science fiction, but these labels really don’t do his books justice.  Often his novels deal with historical events with the supernatural thrown in.  His history is exact, but it is interpreted in his own unique sort of way.

     It probably doesn’t matter in what order the books are read, but I would definitely read these three in order since they are sequels: Last Call, Expiration Date and Earthquake Weather.  These three books are a must read if you are interested in Tim Powers, although all of the others are very good.

     The Anubis Gates is such an incredible and disturbing book that I limit my reading of it because parts of it are actually painful to me.

    If you are interested in unique and strange stories, you must read the novels of Tim Powers.

Here’s some birds I saw in Panama.  The page and plate numbers refer to the Birds of Panama.

We are sentient beings. As conscious entities we often look for meaning in what at first appears to be an uncaring universe.  This seems to be the way we are, constantly seeking for meaning that relates to our own lives.

Religion and philosophy are attempts to render meaning to our lives.  People of long ago, living in constant contact with the natural world, often looked to nature for meaning, searching for meaning in the behavior of animals, in the weather, and in other natural phenomena.

We have a rational, logical side to our nature, and we have the great body of information given to us by science, and by that great tool, the scientific method which can give us demonstrable truth, truth that can be demonstrated to others.

But our soul cries out for other truths, truths that are more subtle than that learned by the blunt tool of science, truths that do not lend themselves easily to demonstration.

There have been times of great emotional storms in my life in which I searched for meaning in the small things about me…times in which I tried to quell the storm within and tried to listen to that “still, small voice” that speaks to us all, but often goes unheard in the turmoil of modern society.

At such times I often go for walks and look for insight in the world about me.  And if I am able to still the waters within,  I often hear things.   This morning I heard the small brook speaking to me.  The rains had lessened recently, and the voice of the little stream had changed, become more melodious and fuller as its flow diminished.  It’s gurgle and burble sounded like an ancient voice that spoke a language that hovered on the edge of comprehensibility.

An eagle sounded as I ambled along, a sound that I have heard so often, that it threatens to become commonplace.  I stopped to listen and to appreciate more fully the wild character of the call.

Then I remembered that two nights ago when I stepped from my car about two hours after midnight, I paused for a second and looked up at a rare, clear, night sky at the Big Dipper.  I remembered how long ago my father pointed out to a small boy how the Big Dipper is always pointing to Polaris, the North Star, and showed me where it points.  I checked, and sure enough, it is still pointing to this guide star.

As I paused there in the darkness, I heard the oh-so-soft hooting of the Great Horned Owl.  It was immediately answered by another.  I had often wondered why I seldom heard owls even though my house is surrounded by forest.   The calls were so faint and soft that I know that I could have easily missed them as I rushed from the car into the house.

So I stood there longer in the darkness, wondering if further mysteries were to be hinted at.  Then far off over the Sound, I heard a growing sound that increased until it sounded like the yapping of hounds in the sky.  For a second I thought of the hunting dogs of Diana, or Artemis, coursing through the night sky in pursuit of some unknown prey.  I shook my head, but the sound remained the same.  I told myself that it was Canada Geese on their northern migration, but I have heard these geese many times, and this did not sound the same.  Whatever it was, it gradually faded, growing fainter until I was left standing in the dark listening to the soft hooting.

Perhaps I should pause more often and slow my pace and open my eyes…and ears…and mind.

I loved the way that this writer found meaning in the birds of a walk that he took.  In fact I admire his entire blog.
