All species are not created equal when assessing the impacts of species loss on ecosystems
Numerous studies have shown that when species are randomly lost from communities, ecosystem function declines. But such patterns of species loss do not reflect those in natural communities where major drivers of change, such as stress and disturbance, cause preferential loss of rare and uncommon species. In the June issue of Ecology Letters, Smith... view more... (2003-05-22)
Possible dinosaur burrows clues to survival strategies
Internationally renowned palaeontologist and Monash University Honorary Research Associate, Dr Anthony Martin has found evidence of a dinosaur burrow along the coast of Victoria, which helps to explain how dinosaurs protected themselves from climate extremes during the Cretaceous period - the final era for dinosaurs before their extinction. view more (2009-07-16)
How to save dogs by environmental enrichment
More dogs can be saved from being destroyed. Small changes in the way they are kept in animal rescue shelters can help the dogs behave in more appealing ways to potential buyers. view more (1999-03-26)
Global warming increases species extinctions worldwide
Global warming has already caused extinctions in the most sensitive habitats and will continue to cause more species to go extinct over the next 50 to 100 years, confirms the most comprehensive study since 2003 on the effects of climate change on wild species worldwide by a University of Texas at Austin biologist. view more (2006-11-15)
UCSB researchers discover the dawn of animal vision
By peering deep into evolutionary history, scientists at the University of California, Santa Barbara have discovered the origins of photosensitivity in animals. view more (2007-10-17)
Next Director of Roslin Institute announced
BBSRC today announced that the scientist behind the transgenic sheep that marked a breakthrough in generating human therapeutic proteins in milk is to be the next Director of the Roslin Institute. Professor John Clark will be appointed as Director of the world's leading animal biotechnology research centre in August 2003. "John is an... view more... (2002-12-18)
New family of antibacterial agents uncovered
As bacteria resistant to commonly used antibiotics continue to increase in number, scientists keep searching for new sources of drugs. In this week's JBC, one potential new bactericide has been found in the tiny freshwater animal Hydra. view more (2009-01-16)
Why does species diversity vary so much?
The diversity of life varies predictably with climate and is greatest where it is warm and wet (the humid tropics). But the question "why" has puzzled biologists for over a century. In the December issue of Ecology Letters, Currie and colleagues examine three hypotheses about the origin of climatic gradients of diversity. The... view more... (2005-01-11)
Big bang in Antarctica — killer crater found under ice
Planetary scientists have found evidence of a meteor impact much larger and earlier than the one that killed the dinosaurs — an impact that they believe caused the biggest mass extinction in Earth's history. view more (2006-06-02)
Do 3 meals a day keep fungi away?
The fact that they eat a lot - and often - may explain why most people and other mammals are protected from the majority of fungal pathogens, according to research from Albert Einstein College of Medicine of Yeshiva University. view more (2009-10-16)
Milk goes 'green': Today's dairy farms use less land, feed and water
Dairy genetics, nutrition, herd management and improved animal welfare over the past 60 years have resulted in a modern milk production system that has a smaller carbon footprint than mid-20th century farming practices. view more (2009-06-11)
Risk models can reduce number of collisions with wild animals
Hundreds of thousands of animals are killed in traffic every year. The threat traffic represents to badgers is greater than was previously known. A new dissertation at the Swedish University of Agricultural Sciences (SLU) illuminates the conflict between traffic and animals in Sweden and provides models that predict the risk of accidents involving... view more...

Drop in daddy long legs is devastating bird populations
Warm summers are dramatically reducing populations of daddy long legs, which in turn is having a severe impact on the bird populations which rely on them for food. view more (2009-03-27)
Oldest animal fossils may have been bacteria
The oldest-known animal eggs and embryos, whose first pictures made the cover of Nature in 1998, were so small they looked like bugs - which, it now appears, they may have been. view more (2006-12-21)
Cell death occurs in the same way in plants, animals and humans
Research has previously assumed that animals and plants developed different genetic programs for cell death. view more (2009-10-14)
Evolution reveals an independent route for diversity in animal form
Researchers have found that Cnidaria, a group of marine animals noted for diverse morphology among its constituent species, actually lacks the ancient "Hox" gene system that is essential for the development of most other animals. view more (2006-05-05)
Cucumber Versus Cucumber
Marine invertebrate called sea cucumber resembles vegetable cucumber by not only shape, but also by some metabolites. The substances produced by the animal can affect the growth of the plant. This study was conducted by Russian biochemists and supported by the RFBR. view more (2004-11-15)
New 150 Million-Year-Old Crab Species Discovered
Researchers from Kent State University and the University of Bucharest, Romania, have discovered a new primitive crab species Cycloprosopon dobrogea in eastern Romania. Previously unexamined, these ancient crabs from the Prosopidae family existed more than 150 million years ago during the Jurassic period. view more (2007-10-18)
Ecstasy could help patients with post-traumatic stress disorder
Ecstasy may help suffers of post-traumatic stress learn to deal with their memories more effectively by encouraging a feeling of safety, according to an article in the Journal of Psychopharmacology published today by SAGE. view more (2009-03-09)
FMD future: vaccines or funeral pyres?
Millions of animals could be needlessly slaughtered and billions of dollars lost from economies, unless the world backs an international science team to develop new tools to fight foot-and-mouth disease (FMD). A group of world-leading researchers aims to develop a more effective FMD vaccine and better diagnostic tests that would enable livestock... view more... (2003-09-29)
