Has Economic Isolation Preserved Cuba’s Stunning Coral Reefs?

Buck Rogers, Staff WriterThe isolation of Cuba from world economy has meant that the Cuban economy has not been as influenced by global corporations and governments as most other modern nations have. The country is a bit “behind the times” when it comes to cars, industry, technology, and basically all of the luxuries that we consider necessities in the typical consumer lifestyle of the 21st century. As a result, not only are the Cuban people seemingly [...]

Skywatch: Venus and Jupiter continue to accentuate the night heavens


Venus (right) & Jupiter


Excerpt from washingtonpost.com
By Blaine Friedlander Jr. 
In winter’s waning weeks, Venus and Jupiter continue to accentuate the night heavens, we change our clocks forward and we grab spring with no intention of letting go.

Check the west-southwestern heavens at dusk to spy the vivacious Venus and the dim Mars. In late February, the two planets met for a sweet cosmic waltz, but in March, they appear to separate. Venus approaches negative fourth magnitude (very bright) while Mars makes do at magnitude 1.3 (dim, hard to find in urban light pollution). With a clear sky, Mars looks like a red pinpoint. 

A young, waxing crescent moon visits Mars on the evening of March 21, and on the next evening the crescent flirts with Venus.
Robust Jupiter ascends the evening’s eastern sky. Find this gas giant at a -2.5 magnitude, very bright, in the constellation Cancer. The lion in the constellation Leo appears to stare at the planet. By the Ides of March, find it south around 10:30 p.m. 

The waxing gibbous moon drops by the dazzling Jupiter on March 2, days before the moon itself becomes full on March 5. 

Catch the ringed Saturn rising after midnight in the east-southeast now, hanging out near a gang of constellations, Scorpius, Ophiuchus and Libra. It’s a zero magnitude object, bright enough that it can be seen under urban skies. The waning moon loiters near Saturn before dawn on March 12. On that morning, the reddish star below them is Antares.
We adjust our clocks to Daylight Saving Time at 2 a.m. March 8. Spring forward, moving the clock ahead one hour. 

Winter is almost over. Spring is weeks away. The vernal equinox brings spring’s official arrival on March 20 at 6:45 p.m. 

Also on March 20 — the day a new moon — the North Atlantic and the Arctic waters get a short total eclipse. We won’t see it here, but Slooh.com will carry it live. Totality will start seconds after 5:44 a.m. and end at 5:47 a.m., according to Geoff Chester of the U.S. Naval Observatory.

Will new ruling finally free Lolita after 40 years in captivity at Miami Seaquarium?



Excerpt from seattletimes.com

A decision to list the captive orca Lolita for federal protection is expected to set the stage for a lawsuit from advocates seeking the whale’s release.

Seattle Times staff reporter



A Puget Sound orca held for decades at Miami’s Seaquarium will gain the protection of the federal Endangered Species Act, a move expected to set the stage for a lawsuit from advocates seeking the whale’s release.

The National Oceanic and Atmospheric Administration (NOAA) announced Wednesday the decision to list Lolita as part of the southern resident killer whales of Puget Sound, which already are considered endangered under the federal act. 

Whale activists, who petitioned for this status, have long campaigned for Lolita’s return to Puget Sound. They hope the listing will provide a stronger legal case to release Lolita than did a previous lawsuit that centered on alleged violations of the federal Animal Welfare Act.

“This gives leverage under a much stronger law,” said Howard Garrett of the Whidbey Island based Orca Network, which hopes a San Juan Island cove will one day serve as the site for Lolita to re-enter the wild.

NOAA Fisheries officials on Wednesday described their decision in narrow terms, which set no broader precedents. It does not address whether Lolita should be released from the Seaquarium.
“This is a listing decision,” said Will Stelle, the NOAA Fisheries regional administrator for the West Coast. “It is not a decision to free Lolita.” 

Aquarium officials have repeatedly said they have no intention of releasing the orca. 

“Lolita has been part of the Miami Seaquarium family for 44 years,” said Andrew Hertz, Seaquarium general manager, in a statement. 

“Lolita is healthy and thriving in her home where she shares habitat with Pacific white-sided dolphins. There is no scientific evidence that ... Lolita could survive in a sea pen or the open waters of the Pacific Northwest, and we are not willing to treat her life as an experiment.”

Orcas, also known as killer whales, are found in many of the world’s oceans. The southern resident population, which spends several months each year in Puget Sound, is the only group listed in the U.S. under the Endangered Species. 

The three pods in the population were reduced by captures by marine parks between 1965 and 1975, NOAA says. Among them was a roundup in Penn Cove where seven whales were captured, including Lolita. 

The southern resident pods now number fewer than 80. Possible causes for the decline are reduced prey, pollutants that could cause reproductive problems and oil spills, according to NOAA Fisheries.
Under the Endangered Species Act, it is illegal to cause a “take” of a protected orca, which includes harming or harassing them.
Wednesday, NOAA officials said holding an animal captive, in and of itself, does not constitute a take. 

Orca activists are expected to argue in their lawsuit that Lolita's cramped conditions result in a prohibited take.

There is “rising public scorn for the whole idea of performing orcas,” said Garrett, who hopes Seaquarium will decide to release Lolita without a court order. 

But NOAA officials still have concerns about releasing captive whales, and any plan to move or release Lolita would require “rigorous scientific review,” the agency said in a statement.
The concerns include the possibility of disease transmission, the ability of a newly released orca to find food and behavior patterns from captivity that could impact wild whales.

NOAA said previous attempts to release captive orcas and dolphins have often been unsuccessful and some have ended in death.

Garrett said the plan for Lolita calls for her to be taken to a netted area of the cove, which could be enlarged later. She would be accompanied by familiar trainers who could “trust and reassure her every bit of the way,” he said. 

The controversy over releasing captive whales has been heightened by the experience of Keiko, a captive orca that starred in the 1993 movie “Free Willy,” about a boy who pushed for the release of a whale.

In 1998, Keiko was brought back to his native waters off Iceland to reintroduce him to life in the wild. That effort ended in 2003 when he died in a Norwegian fjord. 

Garrett, who visited Keiko in Iceland in 1999, said he was impressed by the reintroduction effort, and that there was plenty of evidence that Keiko was able to catch fish on his own.

“The naysayers predicted that as soon as he got into the (Icelandic) waters he would die, and wild orcas would kill him,” Garrett said. “He proved that 180-degrees wrong. He loved it.”

Mark Simmons, who for two years served as director of animal husbandry for the Keiko-release effort, has a different view. He says Keiko never was able to forage for fish on his own, and that he continued to seek out human contact at every opportunity. 

Simmons wrote a book called “Killing Keiko,” that accuses the release effort of leading to a long slow death for the orca, which he says lacked food and then succumbed to an infection.

“It’s not really the fact that Keiko died, but how he died,” Garrett said Wednesday.

Scientists discover organism that hasn’t evolved in more than 2 billion years

Excerpt from natmonitor.com
By Justin Beach

If there was a Guinness World Record for not evolving, it would be held by a sulfur-cycling microorganism found off the course of Australia. According to research published in the Proceedings of the National Academy of Sciences, they have not evolved in any way in more than two billion years and have survived five mass extinction events.
According to the researchers behind the paper, the lack of evolution actually supports Charles Darwin’s theory of evolution by natural selection.
The researchers examined the microorganisms, which are too small to see with the naked eye, in samples of rocks from the coastal waters of Western Australia. Next they examined samples of the same bacteria from the same region in rocks 2.3 billion years old. Both sets of bacteria are indistinguishable from modern sulfur bacteria found off the coast of Chile.





“It seems astounding that life has not evolved for more than 2 billion years — nearly half the history of the Earth. Given that evolution is a fact, this lack of evolution needs to be explained,” said J. William Schopf, a UCLA professor of earth, planetary and space sciences in the UCLA College who was the study’s lead author in a statement.
Critics of Darwin’s theory of evolution might be tempted to jump on this discovery as proof that Darwin was wrong, but that would be a mistake.
Darwin’s work focused more on species that changed, rather than species that didn’t. However, there is nothing in Darwin’s work that states that a successful species that has found it’s niche in an ecosystem has to change. Unless there is change in the ecosystem or competition for resources there would be no reason for change.
“The rule of biology is not to evolve unless the physical or biological environment changes, which is consistent with Darwin. These microorganisms are well-adapted to their simple, very stable physical and biological environment. If they were in an environment that did not change but they nevertheless evolved, that would have shown that our understanding of Darwinian evolution was seriously flawed.” said Schopf, who also is director of UCLA’s Center for the Study of Evolution and the Origin of Life.
It is likely that there were genetic mutations in the organisms. Mutations are fairly random and happen in all species, but unless those mutations are improvements that help the species function better in the environment, they usually do not get passed on.
Schopf said that the findings provide further proof that Darwin’s ideas were right.
The oldest fossils analyzed for the study date back to the Great Oxidation Event. This event, which occurred between 2.2 and 2.4 billion years ago, saw a substantial increase in Earth’s oxygen levels. That period also saw an increase in sulfates and nitrates, which is all that the microorganisms would have needed to survive and reproduce.
Shopf and his team used Raman spectroscopy, which allows scientists to examine the composition and chemistry of rocks as well as confocal laser scary microscopy to generate 3-D images of fossils embedded in rock.
The research was funded by NASA Astrobiology Institute, in the hope that it will help the space agency to find life elsewhere.

Is this the Loch Ness Monster? Scientists discover new species of "uniquely Scottish" boat-sized Jurassic reptile on Isle of Skye




Excerpt 

A 14-foot long, dolphin-like ichthyosaur would have swum the warm, shallow seas near Scotland during the Jurassic period, according to scientists who have identified an entirely new species from a “very special” set of bones found by an amateur enthusiast in 1959 and given to Glasgow’s Hunterian Museum.

The largest group of palaeontologists ever to have worked together in Scotland believe fossil fragments of skulls, teeth, vertebrae and an upper arm bone would have belonged to a previously unknown type of long-extinct aquatic animal, named the Dearcmhara shawcrossi after Brian Shawcross, who recovered the fossils from the island’s Bearreraig Bay.

partly in homage to the history of the Hebrides and Skye, much of which was underwater during Jurassic times. Some reports have likened the predator to an ancestor of the Loch Ness monster.

“During the time of dinosaurs, the waters of Scotland were prowled by big reptiles the size of motor boats,” explained Dr Steve Brusatte, of the University of Edinburgh’s School of GeoSciences, who led the study.

“Their fossils are very rare, and only now, for the first time, we’ve found a new species that was uniquely Scottish.

“Without the generosity of the collector who donated the bones to a museum instead of keeping them or selling them, we would have never known that this amazing animal existed.

“We are honoured to name the new species after Mr Shawcross and will do the same if any other collectors wish to donate new specimens.”

The creature was near the top of the food chain 170 million years ago, preying on fish and other reptiles during an age when Skye was joined to the rest of the UK as part of a large island positioned between landmasses that gradually drifted apart to become Europe and North America.


“Not only is this a very special discovery, but it also marks the beginning of a major new collaboration involving some of the most eminent palaeontologists in Scotland,” said Dr Nick Fraser, of National Museums Scotland.

Extraordinary’ 5,000-Year-Old Human Footprints Discovered

Excerpt from livescience.com

When a pair of fishermen waded into the frigid waters of the southern Baltic Sea about 5,000 years ago, they probably didn't realize that the shifting seabed beneath their feet was recording their every move. But it was.




The long-lost evidence of that prehistoric fishing trip — two sets of human footprints and some Stone Age fishing gear — was recently discovered in a dried up fjord, or inlet, on the island of Lolland in Denmark. There, archaeologists uncovered the prints alongside a so-called fishing fence, a tool that dates back to around 3,000 B.C.


Archaeologists have found fishing fences before, but the footprints are the first of their kind discovered in Denmark, according to Terje Stafseth, an archaeologist with the Museum Lolland-Falster, who helped excavate the ancient prints. 


"This is really quite extraordinary, finding footprints from humans," Stafseth said in a statement. "Normally, what we find is their rubbish in the form of tools and pottery, but here, we suddenly have a completely different type of trace from the past, footprints left by a human being."


The Stone Age footprints were likely formed sometime between 5,000 B.C. and 2,000 B.C., Jensen said. At that time, the water level of the Baltic Sea was rising due to melting glaciers in northern Europe. Also at that time, prehistoric people were using these inlets as fishing grounds.

These individuals constructed elaborate traps, called fishing fences, to catch their prey. The wooden fences were built in sections several feet wide — thin switches of hazel suspended between two larger sticks — and the sections were lined up consecutively to form one long, continuous trap. The trap was placed in the shallow water of the fjord, which would be flooded with the incoming tide, the archaeologists said. When the fishermen wanted to move their gear, they would pluck the sections of the fence from the claylike floor of the fjord and move the whole apparatus to a new location.

"What seems to have happened was that at some point they were moving out to the [fish fence], perhaps to recover it before a storm," Jensen said. "At one of the posts, there are footprints on each side of the post, where someone had been trying to remove it from the sea bottom."



The archaeologists said the footprints must have been made by two different people, since one set of prints is significantly smaller than the other. Jensen and his team are now making imprints, or flat molds, of the footprints to preserve these ancient signs of life.

In addition to the human tracks, the team uncovered several skulls belonging to domestic and wild animals on the beach near the fjord.

The researchers said the skulls were likely part of offerings made by local farmers, who inhabited the region from around 4,000 B.C.

"They put fragments of skulls from different kinds of animals [on the sea floor], and then around that they put craniums from cows and sheep," Jensen said. "At the outermost of this area, they put shafts from axes. All in all, it covers about 70 square meters [83 square yards]. It's rather peculiar."

Kermit the Frog maybe, but are we really suppossed to believe humans evolved from this guy? Greg Giles


An artist's rendition of the amphibious Cartorhynchus lenticarpus. (Stefano Broccoli)


In a Nov. 5th article penned by Rachel Feltman(washingtonpost.com) entitled Newly discovered fossil could prove a problem for creationists (But apparently not a really big problem), a report published in the journal Nature claims to have discovered the missing link proving that modern man has evolved from a sometimes aquatic, sometimes not, (he apparently changed his mind once or twice about which direction he wanted to evolve) little green fish/frog/alligator/lizardy type character named Cartorhynchus lenticarpus. Although I chuckled all through the unsubstantiated claims of the report's lead author Ryosuke Motani, one of my favorite moments had to be when Motani describes his brainstorming activity. "Initially I was really puzzled by this fossil. I could tell it was related [to ichthyosaurs], but I didn't know how to place it. It took me about a year before I was sure I had no doubts." (Wait Ryosuke, go back to that moment in time while you were kicking an empty soda can around your neighborhood while trying to figure out how you could pound a square green peg into a round hole. I think that's where your theory may have gone slightly askew.)

My absolute favorite moment of the study though had to be the team's conclusion that the foot and a half long green amphibian "probably had a happy life". I could see now a room full of white lab coats concurring with one another. "Yes yes, happy indeed. I concur." A young lab technician then sheepishly speaks up. "I must disagree sirs. My research shows its not easy being green." "Oh yes, yes," the group of senior scientists now concede. "Indeed, it's not easy being green." 

Motani's statement that his team now hopes to find the preceding evolutionary ancestor to Cartorhynchus lenticarpus as their next major breakthrough is the part of this report that I can't get out of my mind. What would the odds be that this small group of researchers not only find one crucial missing link, but will also discover the very next missing piece of the long evolutionary puzzle chain, evidence countless archeologists, scientists and researchers have been, for centuries, turning over stones in search of. Something smells fishy here, and it isn't the great, great, great grandfather of Kermit the Frog.  
Greg Giles

Excerpts from the washingtonpost.com article by Rachel Feltman:

Researchers report that they've found the missing link between an ancient aquatic predator and its ancestors on land. Ichthyosaurs, the dolphin-like reptiles that lived in the sea during the time of the dinosaurs, evolved from terrestrial creatures that made their way back into the water over time.

But the fossil record for the lineage has been spotty, without a clear link between land-based reptiles and the aquatic ichthyosaurs scientists know came after. Now, researchers report in Nature that they've found that link — an amphibious ancestor of the swimming ichthyosaurs named  Cartorhynchus lenticarpus.

"Many creationists have tried to portray ichthyosaurs as being contrary to evolution," said lead author Ryosuke Motani, a professor of earth and planetary sciences at the University of California Davis. "We knew based on their bone structure that they were reptiles, and that their ancestors lived on land at some time, but they were fully adapted to life in the water. So creationists would say, well, they couldn't have evolved from those reptiles, because where's the link?"

Now the gap has been filled, he said.

The creature is about a foot and a half long and lived 248 million years ago.

"Initially I was really puzzled by this fossil," Motani said. "I could tell it was related [to ichthyosaurs], but I didn't know how to place it. It took me about a year before I was sure I had no doubts."

One of the most important differences between this new ichthyosaur and its supposed descendants comes down to being big boned: When other vertebrates have evolved from land to sea living, they've gone through stages where they're amphibious and heavy. Their thick bones probably allowed them to fight the power of strong coastal waves and stay grounded in shallow waters. Sure enough, this new fossil has much thicker bones than previously examined ichthyosaurs.

"This animal probably had a happy life. It was in the tropics, and it was probably a bottom feeder that fed on soft-bodied things like squid and animals like shrimp," Motani said. "And for a predator like that to exist, there has to be plenty of prey. This was probably one of the first predators to appear after that extinction."

This single fossil hasn't revealed all of the ichthyosaurs' secrets. Motani hopes to find the preceding evolutionary ancestor next — one that was also amphibious, but spent slightly more of its time on land. "We're looking for that one now," Motani said.
