Hi everyone, There are about 32 different species of dolphins. Just recently the Yangtze also known as the Baji dolphin has just been declared extinct. It is the first large extinction of a vertabrate form more than fifty years, and the only species of (Dolphin,Whale or Porpoise) ever to be driven to extinction by human activity. The Bottle-Nose Dolphin is the most common dolphin seen in the England Waters. Once we went out on our rubber dingy in Lyme Regis and there was a bottle-nose dolphin swimming aroung the boat….It was fantastic! The Zooilogical Society of London (ZSL) has revealed that there were more than 100 Dolphin, Seal, and Porpoise sightings in the Thames last year (2006) If you would like to support Dolphins visit www.wdcs.org . You can adopt a dolphin for just £3.00 a month.

Recovering from a mass extinction / From: University of Bristol / Published January 18, 2008 10:06 AM / / The full recovery of ecological systems, following the most devastating extinction event of all time, took at least 30 million years, according to new research from the University of Bristol. / About 250 million years ago, at the end of the Permian, a major extinction event killed over 90 per cent of life on earth, including insects, plants, marine animals, amphibians, and reptiles. Ecosystems were destroyed worldwide, communities were restructured and organisms were left struggling to recover. This was the nearest life ever came to being completely wiped out. / Previous work indicates that life bounced back quite quickly, but this was mostly in the form of ”˜disaster taxa’ (opportunistic organisms that filled the empty ecospace left behind by the extinction), such as the hardy Lystrosaurus, a barrel-chested herbivorous animal, about the size of a pig. / The most recent research, conducted by Sarda Sahney and Professor Michael Benton at the University of Bristol and published in Proceedings of the Royal Society B this week, indicates that specialised animals forming complex ecosystems, with high biodiversity, complex food webs and a variety of niches, took much longer to recover. / Sahney said: “Our research shows that after a major ecological crisis, recovery takes a very long time. So although we have not yet witnessed anything like the level of the extinction that occurred at the end of the Permian, we should nevertheless bear in mind that ecosystems take a very long time to fully recover.” / Sahney and Benton looked at the recovery of tetrapods — animals with a backbone and four legs, such as amphibians and reptiles — and found that although globally tetrapods appeared to recover quickly, the dramatic restructuring that occurred at the community level was not permanent and communities did not recover numerically or ecologically until about 30 million years later. / Professor Benton explained: “Diversity is most commonly assessed by tallying the number of taxa on a global scale, but these studies are subject to the vagaries of sampling. By examining well-preserved and well-studied faunas, the taxonomic and ecological recovery of communities after the Permian extinction event can be examined more accurately, and the problems of geological bias are largely avoided.” / The Permian extinctions occurred in three waves, the largest being at the boundary between the Permian and Triassic periods, 251 million years ago. This was the most devastating ecological event of all time, thought to be caused by large-scale volcanism in Russia which produced the ”˜Siberian Traps’, covering over 200,000 square kilometers (77,000 square miles) in lava. / / From: Jesse Boyett Anderson, Stanford News Service / Published August 10, 2007 04:49 PM / What A 250-Million-Year-Old Extinction Event Tells Us About Earth Today / / August 8, 2007 Stanford University—Approximately 250 million years ago, vast numbers of species disappeared from Earth. This mass-extinction event may hold clues to current global carbon cycle changes, according to Jonathan Payne, assistant professor of geological and environmental sciences. Payne, a paleobiologist who joined the Stanford faculty in 2005, studies the Permian-Triassic extinction and the following 4 million years of instability in the global carbon cycle. In the July issue of the Geological Society of America Bulletin, Payne presented evidence that a massive, rapid release of carbon may have triggered this extinction. “People point to the fossil record as a place where we can learn about how our actions today may affect the future course of evolution,” Payne said. “That’s certainly true: The deep geologic record provides context for modern events. We may miss very important processes or underestimate the magnitude of changes in the future by using only the past couple thousand years as a baseline.” Great Bank of Guizhou Payne has spent the past five years unearthing the deep geologic record in south China. The kilometer-thick, limestone fossil beds at the Great Bank of Guizhou formed in shallow ocean waters during the late Permian and early Triassic periods. As the ocean floor sank, new, younger layers of limestone formed on top of deeper, older ones. Since then, plate tectonics have turned these rocks on their side. Now, Payne and his colleagues can walk back in time across the formerly horizontal layers. Marine fossil beds such as these offer two advantages for someone studying broad patterns in the history of life, according to Payne. Because ocean waters cover large areas for long periods of time and somewhat protect the underlying rocks from erosion, marine fossil beds tend to be physically larger and cover a longer period of time with finer temporal resolution. More than 90 percent of all marine species disappeared from the Great Bank of Guizhou and other end-Permian fossil formations 250 million years ago. Land plants and animals suffered similar losses. Douglas Erwin, curator of the Paleozoic invertebrates collection at the Smithsonian National Museum of Natural History, has dubbed this event “the greatest biodiversity crisis in the history of life.” An unusually long period of time passed before biological diversity began to reappear. Scientists disagree on the causes of this extinction. However, nearly all explanations cite the high levels of greenhouse gases, including carbon dioxide, low levels of oxygen in the oceans and high levels of toxic gases. Siberian Traps In 1991, scientists reported that the largest known volcanic event in the past 600 million years occurred at the same time as the end-Permian extinction. Magma extruded through coal-rich regions of the Earth’s crust and blanketed a region the size of the continental United States with basalt to a depth of up to 6 kilometers. The eruptions that formed the Siberian Traps not only threw ash, debris and toxic gases into the atmosphere but also may have heated the coal and released vast quantities of carbon dioxide and methane into the atmosphere. Rapid release of these greenhouse gases would have caused the oceans first to become acidic and then to become supersaturated with calcium carbonate. In the July Bulletin, Payne presents evidence that underwater limestone beds around the world eroded at the time of the end-Permian extinction. This finding, coupled with geochemical evidence for changes in the relative abundances of carbon isotopes, strongly suggests an acidic marine environment at the time of the extinction. The rock layers immediately covering this eroded surface include carbonate crystal fans, which indicate oceans supersaturated with calcium carbonate. “This end-Permian extinction is beginning to look a whole lot like the world we live in right now,” Payne said. “The good news, if there is good news, is that we have not yet released as much carbon into the atmosphere as would be hypothesized for the end-Permian extinction. Whether or not we get there depends largely on future policy decisions and what happens over the next couple of centuries.” Coral reefs Payne plans to learn more about the causes and consequences of this massive extinction event this summer. Three students left Aug. 1 to join him in southern China for four weeks of field studies. If volcanic activity released sufficient quantities of carbon into the air within less than 100,000 years, the Earth would have transiently cooled and then experienced a prolonged period of global warming, Payne said. This summer, Ellen Schaal, a graduate student in the Department of Geological and Earth Sciences, will use one geochemical index to try to understand how climate did change during the end-Permian period. Two other students will examine coral reef structures. The Great Bank of Guizhou contains the fossilized reefs from just before and just after this extinction event. Undergraduate Mindi Summers hopes to describe the ecological structure of coral reefs just before the extinction, and graduate student Brian Kelley will study the development and diversification of reefs after the global carbon cycle began to stabilize. Reef communities are a sort of canary in the mineshaft, Payne explained. Today, coral reef health is considered a measure of environmental stability. When stressed by environmental conditions, the algae that inhabit the reef leave, and the reef loses color—and one reason why algae might leave is temperature. For example, when ocean temperatures rise during El Niño years, corals bleach. This type of immediate response to environmental change is hard to track in the geologic record. “We hope to reconcile the short-term processes we observe operating in the modern world with the very long time scales seen in the geologic record,” said Seth Finnegan, a postdoctoral scholar in Payne’s lab.

My Amur Leopard / / ...
My Amur Leopard / / / Most of you know that I spend a lot of time at the Philadelphia Zoo, in PA. I do have to say, I wish I lived next door instead of an hour away, but as I make the busy drive into Pennsylvania (from NJ) and have to wait in traffic as I try to make my way to the other side of Philadelphia, my thoughts are always, always with one animal that I just can’t wait to see. Yes, the baby Amur Tigers were stunning, when they were babies, but I always ended up at MY AMUR LEOPARD. The two photos above, the first one is the Male and the second is the Female The Amur Leopard is the rarest and critically endangered cat in the world. It is said that there is fewer that 40 of these majestic cats left in the wild, due to habitat loss and natural disasters such as fires, not to mention poaching. It is hard to believe when I see these stunning cats that they are becoming to be extinct in the wild To learn more please visit Amur Leopard

This Sunday 7 September marks National Threatened Species Day in Australia so I hope you can all take some time to reflect on what we have done in the past to contribute to the loss of our fauna and flora, but more importantly, what we might be doing now. Tiger Bot has been a runaway (no pun intended) success for me. Obviously I am very happy that people like the design and can relate to it, but I can’t help but be a little bit sad that one of the reasons we are fascinated by this creature is because we haven’t seen one since 1936. Unfortunately Tasmania is fast becoming the ‘poster’ state for threatened species – you only have to look at the current crisis surrounding Devil Facial Tumour Disease to realise that extinction is not something that only occurred years ago, but is a very real and present threat.

/ BRAG TIME! / if you’re in Melbourne, you can go to Federation Square and watch a film called CORAL SEA DREAMING 2, an epic undersea film of magnificent cinematography by Australia’s own Emmy Award-winner David Hannan and music by yours truly, Tania Rose. This film is an extraordinary visual feast, and is probably the last we will see of much of the marine life of the coral reefs, as the reefs around the globe are as we speak becoming extinct :(. David is the world leader of undersea cinematography and provides a lot of footage for marine scientists and their studies. Shot in Hi-Definition, Coral Sea Dreaming 2 is a collection of his best work. It is indeed both an honour and a privilege to be involved in this project, on many levels, not least of which is the fact that this is both a celebration and a tribute to something the Earth is losing with dire consequences. The earth is precious…more precious than ourselves
This video is a compilation of videos that I downloaded some time ago. I just joined them together and added a backing track.
This video is a compilation of videos that I downloaded some time ago. I just joined them together and added a backing track. This is the Thylacine or Tasmanian Tiger, a carnivorous marsupial last positively seen in Hobart Zoo, where the last known animal died in 1932. Mind you, it didn’t receive protection until about 1974. There are still reports of sightings but these are still only anecdotal. They may be real but there is no positive proof for the rest of us. They are/were so beautiful.
