They are now classified as Critically Endangered.

And it's working. TEDTalks is a daily video podcast of the best talks and performances from the TED Conference, where the world's leading thinkers and doers give the talk of their lives in 18 minutes. Featured speakers have included Al…

Animals?, perfume, Obsession for Men, Bronx Zoo, Wildlife Conservation Society, conservation biology, behavioral ecology, animals, mammals, big cats, weird, strange, wow, streaming video This fascinating video shows that Calvin Klein's "Obsession for Men" is NOT just for men! This is a great example of how careful observation of captive animals' behavior is directly impacting research with wild animals. When biologists at the Bronx Zoo started spritzing "Obsession for Men" cologne near heat-and-motion-sensitive cameras, the tigers, snow leopards, jaguars and cheetahs…

BP has contracted bird rescue groups to rehabilitate wildlife affected by the Deepwater Horizon oil spill. The birds are examined, thoroughly washed and then allowed to…

But because humans also like to live on islands, along with their pets and crop plants, islands are a conservation nightmare, and certainly, the Hawai'ian islands are no exception. In Alvin Powell's book, The Race to Save…
This video from WDSU shows Mr. Green Genes, the transgenic kitty, in the dark and in the light. There's also an interview with Dr. Betsy Dresser, who very briefly talks about the work at the Audubon Center for Research on Endangered Species. Other than clips of the cat, and Dr. Dresser, the video mostly shows people taking frozen samples out of liquid nitrogen, but there's an interesting bit towards the end where they show a pipette transferring material into the nucleus of an egg cell. Mr. Green Genes is certainly a cute cat. You can see more pictures from the Times Picayune: here and…

Image: Tony Randell (Wikipedia) [larger view]. Every once in awhile, I read a paper that surprises me. Today, I read one of those papers, and it surprised me because it analyzes a phenomenon that is so obvious that I wonder why no one ever thought of studying it in a systematic and rigorous way before. I am referring to a paper that was just published by a team of…
Genetics textbooks abound with stories of European royalty and the hazards of having children after you've married one of your cousins. It struck me as an interesting parallel that the lion is such a popular symbol in so many royal coats of arms. Like the royal families of Europe, certain lion populations have also suffered from a few too many copies of certain recessive genes. I first read about the Florida panthers a few years ago while researching material for a class that I teach on using bioinformatics. It wasn't my first encounter with big cats and their DNA. Years before, while…
Her name is Flora and she is a single parent. Born in Miami, Flora moved to Chester, UK, as a toddler. Now, she's almost 8 years old and starting a family, all on her own. Literally. Four eggs have hatched and another eight are ready to go. Yet, Flora has never gotten cozy with another male dragon. How did Flora accomplish this feat and how do we know that she's not just good at keeping secrets? Flora's not the only one Parthenogenesis -- reproduction without the need for fertilization by a male -- has been observed before in about 70 vertebrate species, including snakes and monitor…
