Cricket's finicky mating behavior boosts biodiversity
Biologists at Lehigh University and the University of Maryland have identified a cricket living in Hawaii's forests as the world's fastest-evolving invertebrate. Females in the Laupala genus detect tiny differenc...Biodiversity hotspots identify conservation priorities
The new book Hotspots Revisited identifies 34 regions worldwide where 75 percent of the planet's most threatened mammals, birds, and amphibians survive within habitat covering just 2.3 percent of the Earth's surface (roughly equivalent to the combined areas of the five largest U.S. states). This habitat originally covered 15.7 percent of the Earth's surface, an area equivalent in size to Russia a...Stanford gut check shows diversity of intestinal ecosystem
The universe of microbes that lives in your stomach may be nearly as unique as your fingerprint, according to researchers at the Stanford University School of Medicine who have embarked on the early stages of exploring the intestinal ecosystem. Using molecular techniques that detect all known types of microbes and borrowing statistical techniques from field ecology and population genetics,...Analysis of Bacterial Assemblage Genetic Diversity in Environmental Samples Using the DCode System
Derek Cody and Laura G. Leff, Department of Biological Sciences, Kent StateUniversity, Kent, Ohio Assessing bacterial genetic diversity in natural environments is problematic because of difficulties in culturing native bacteria and the large number of species that may be encountered. The morpho...Monitoring Bacterial Genetic Diversity in a Freshwater Lake Using TTGE and DNA Sequence Analysis
School of Biological Sciences, University of Liverpool, Liverpool, UK Microbial ecology is now firmly focused on the genotypic analysis of naturally-occurring assemblages as facilitated by the development of molecular biological techniques t...Obstructionists block network routing diversity
Making network infrastructure more reliable in this post 9/11 era should be everyone's goal, whether they are part of the government, a network carrier, or a business with mission-critical network needs. This endeavor should transcend any petty competitive issue. Having the best network infrastructure globally is a matter of national defense as well as strategic nat...Diversity still an elusive goal in IT, other tech fields
Former Harvard president Lawrence H. Summers created a firestorm last year when he suggested that female under-representation in math and science fields might be the result of intrinsic aptitude differences between men and women. While that comment may be only part of the reason Summers is the former president of Harvard, it focused the spotlight on the need for more diversity in science and tech...Livers Transplantation Rates Rise Due To an Increased Diversity of Donors
Liver is one of the most sought after solid organ. In UK there is an increase in demand as there is a rise in the death of number of patients who do not receive transplants.// Hence it was decided that a non-heart beating donor is potentially to increase the supply of organs by as much as 20%. This was reported in the British Medical Journal. They say that it will boost the supply of...Gender Difference In Pain Experience Explained By Brain Diversity
Functional and structural difference in the brain can explain why men and women experience pain differently and respond in unique ways to the effects// of certain pain-relief drugs, reveals a new study conducted by researchers at Georgia State University and the Atlanta-based Center for Behavioral Neuroscience (CBN). Although the study has been conducted on rat brains, the results highl...Southern states join hands to protect biodiversity
Forests ministers of the four southern states have decided to form a cell for better cooperation to protect and preserve the biodiversity //of their rich forests. "We have decided to form protocols for joint action raids and protection camps among the southern states," Karnataka Forest Minister C. Chennigapa told reporters here Saturday after the conclusion of a two-day conference of...Indians Add to Rich Diversity of Virginia Tech
A sizeable number of students and faculty of Indian origin add to the rich ethnic diversity seen on the sprawling campus of Virginia Tech,// some 430 km from here, where a gunman went on a shooting spree Monday and killed 33 people, including a professor of Indian origin. Founded in 1872, the Virginia Polytechnic Institute and State University as the institution is formally called, ha...
