Poison dart frog mimics gain when birds learn to stay away
Studying neotropical poison dart frogs, biologists at the University of Texas at Austin uncovered a new way that the frog species can evolve to look similar, and it hinges on the way predators learn to avoid the toxic, brightly colored amphibians. view more (2006-03-09)
New CU-Boulder study shows diversity decreases chances of parasitic disease
A new University of Colorado at Boulder study showing that American toads who pal around with gray tree frogs reduce their chances of parasitic infections known to cause limb malformations has strong implications for the benefits of biodiversity on emerging wildlife diseases. view more (2008-10-22)
Building disease-beating wheat
Disease resistance genes from three different grass species have been combined in the world's first 'trigenomic' chromosome, which can now be used to breed disease resistant wheat varieties. view more (2007-12-13)
No joy in discoveries of new mammal species -- only a warning for humanity, Paul Ehrlich says
In the era of global warming, when many scientists say we are experiencing a human-caused mass extinction to rival the one that killed off the dinosaurs, one might think that the discovery of a host of new species would be cause for joy. view more (2009-02-10)
Cold is hot in evolution — UBC researchers debunk belief species evolve faster in tropics
University of British Columbia researchers have discovered that contrary to common belief, species do not evolve faster in warmer climates. view more (2007-03-16)
New bacteria contaminate hairspray
Scientists in Japan have discovered a new species of bacteria that can live in hairspray, according to the results of a study published in the March issue of the International Journal of Systematic and Evolutionary Microbiology. view more (2008-03-10)
New, rare and threatened species discovered in Ghana
Scientists exploring one of the largest remaining blocks of tropical forest in Western Africa discovered significant populations of new, rare and threatened species underscoring the area's high biological diversity and value. view more (2007-12-07)
Biodiversity and resilience of coral reefs
With over 3000 fish species, Indo-Pacific coral reefs represent one of the most diverse ecosystems on the globe. It is easy to assume that the loss of one or two species from these systems would have little impact. However, in an article in the April issue of Ecology Letters, Bellwood and colleagues document major changes in Indo-Pacific coral... view more... (2003-04-08)
Evolution is driven by gene regulation
It is not just what's in your genes, it's how you turn them on that accounts for the difference between species - at least in yeast - according to a report by Yale researchers in this week's issue of Science. view more (2007-08-10)
Barcoding endangered sea turtles
Conservation geneticists who study sea turtles have a new tool to help track this highly migratory and endangered group of marine animals: DNA barcodes. view more (2009-09-15)
Genetic Analysis of Asian Elephants in India Reveals Some Surprises
Researchers in India and from The Earth Institute at Columbia University have discovered that one of the few remaining populations of Asian elephants in India is actually two genetically distinct groups. view more (2005-12-20)
Meteor no longer prime suspect in great extinction
The greatest mass extinction in Earth's history also may have been one of the slowest, according to a study that casts further doubt on the extinction-by-meteor theory. view more (2007-10-25)
A Genome May Reduce Your Carbon Footprint
With the costs of genome sequencing rapidly decreasing, and with the infrastructure now developed for almost anyone with access to a computer to cheaply store, access, and analyze sequence information, emphasis is increasingly being placed on ways to apply genome data to real world problems, including reducing dependency on fossil fuel. view more (2009-05-13)
Revealing the evolutionary history of threatened sea turtles
It's confirmed: Even though flatback turtles dine on fish, shrimp, and mollusks, they are closely related to primarily herbivorous green sea turtles. view more (2008-10-16)
Fossil and molecular evidence reveals the history of major marine biodiversity hotspots
The journal "Science" has published in the issue of the 1st of August the results of a detailed research work about the evolution of marine diversity all through the last 50 million years. view more (2008-08-07)
Dinosaur extinction didn't cause the rise of present-day mammals, claim researchers
A new, complete 'tree of life' tracing the history of all 4,500 mammals on Earth shows that they did not diversify as a result of the death of the dinosaurs, says new research published in Nature today. view more (2007-03-29)
The song doesn't remain the same in fragmented bird populations
The song of passerine birds is a conspicuous and exaggerated display shaped by sexual selection in the context of male-male competition or mate attraction. At the level of the individual, song is considered an indicator of male 'quality'. view more (2008-03-19)
Female mice can identify inbred males by their scent
Scientists at the University of Liverpool have found that female mice avoid mating with inbred males by 'sensing' the diversity of a protein type in their urine. view more (2008-04-21)
Global ocean sampling expedition
In three new metagenomic studies published online in the open-access journal PLoS Biology, Craig Venter and his team take advantage of the vast amount of microbial sequence data collected during their Sorcerer II Global Ocean Sampling (GOS) expedition to reveal an unprecedented level of genetic and protein diversity in marine microbes. view more (2007-03-14)
Diversity of plant-eating fishes may be key to recovery of coral reefs
For endangered coral reefs, not all plant-eating fish are created equal. A report scheduled to be published this week in the early edition of the journal Proceedings of the National Academy of Sciences suggests that maintaining the proper balance of herbivorous fishes may be critical to restoring coral reefs, which are declining dramatically... view more...
