New book series hopes to inspire research in world's 'hottest biodiversity hotspot'

(01/17/2012) Entomologist Dmitry Telnov hopes his new pet project will inspire and disseminate research about one of the world's last unexplored biogeographical regions: Wallacea and New Guinea. Incredibly rich in biodiversity and still full of unknown species, the region, also known as the Indo-Australian transition, spans many of the tropical islands of the Pacific, including Indonesia's Sulawesi, Komodo and Flores, as well as East Timor—the historically famous "spice islands" of the Moluccan Archipelago—the Solomon Islands, and, of course, New Guinea. Telnov has begun a new book series, entitled Biodiversity, Biogeography and Nature Conservation in Wallacea and New Guinea, that aims to compile and highlight new research in the region, focusing both on biology and conservation. The first volume, currently available, also includes the description of 150 new species.


Global warming causes sheep to shrink

(07/02/2009) Climate change is shrinking Scotland's wild Soay sheep despite the evolutionary advantages of having a large body, report researchers writing in the journal Science. The results suggest that the decrease is primarily an ecological response to environmental variation over the last 25 years, rather than evolutionary change.


Sex differences fuel evolution

(05/10/2007) Some Caribbean lizards' strong sexual dimorphism allows them to colonize much larger niches and habitats than they might otherwise occupy, allowing males and females to avoid competing with each other for resources and setting the stage for the population as a whole to thrive. The finding, reported this week in the journal Nature, suggests sex differences may have fueled the evolutionary flourishing of the Earth's wildly diverse fauna in a way not previously appreciated by scientists.


Animals on islands more abundant than mainland

(04/30/2007) A comprehensive survey of lizards on islands around the world has confirmed what island biologists and seafaring explorers have long observed: Animals on islands are much more abundant than their counterparts on the mainland.


World's only blue lizard heads toward extinction

(03/07/2007) High above the forest floor on the remote Colombian island of Gorgona lives a lizard with brilliant blue skin, rivaling the color of the sky. Anolis gorgonae, or the blue anole, is a species so elusive and rare, that scientists have been unable to give even an estimate of its population. Due to the lizard&spod;s isolated habitat and reclusive habits, researchers know little about the blue anole, but are captivated by its stunning coloration.


Fragmentation killing species in the Amazon rainforest

(11/27/2006) Forest fragmentation is rapidly eroding biodiversity in the Amazon rainforest and could worsen global warming according to research to be published this week in the journal Proceedings of the National Academy of Sciences. "Rainforest trees can live for centuries, even millennia, so none of us expected things to change too fast. But in just two decades-a wink of time for a thousand year-old tree-the ecosystem has been seriously degraded." said Dr. William Laurance, a scientist at the Smithsonian Tropical Research Institute in Panama and leader of the international team of scientists that conducted the research.
