Birds with a nose for a difference (7/2/2009)

Avoidance of inbreeding is evident among humans, and has been demonstrated in some shorebirds, mice and sand lizards. Researchers writing in the open-access journal BMC Evolutionary Biology now report that it also occurs in a strictly monogamous species of bird, suggesting that the black-legged kittiwake possesses the ability to choose partners with a very different genetic profile. ...> Full Article


The faster they come (7/1/2009)

In many animal species stable hierarchies are routinely formed in which some individuals seem to slip naturally into their dominant role whereas others resign themselves to play the part of lowly subordinates. Researchers will present their findings at the Society for Experimental Biology meeting on Sunday, June 28, where they discuss why subordinates embrace this fate so readily instead of putting up a fight. ...> Full Article


Two is not company -- as far as fish are concerned (7/1/2009)

Research at the Universities of Plymouth and Exeter has shown that fish kept alone or in small groups are more aggressive and exhibit fewer natural behaviors such as shoaling. Dr Katherine Sloman will discuss the findings and their implications for welfare guidelines for aquarium fish at the Society for Experimental Biology meeting on Monday June 29. ...> Full Article


Straighten up and fly right: Moths benefit more from flexible wings than rigid (7/1/2009)

Straighten up and fly right: Moths benefit more from flexible wings than rigidNew research using high-speed digital imaging shows that, at least for some insects, wings that flex and deform, something like what happens to a heavy beach towel when you snap it to get rid of the sand, are the best for staying aloft. ...> Full Article


Mice run faster on high-grade oil (6/30/2009)

Between the 1932 and 2008 Olympic Games, world record times of the men's 100m sprint improved by 0.6 seconds. Scientists at the Research Institute of Wildlife Ecology in Austria have shown that an equivalent improvement can be achieved in mice by feeding them a diet high in a certain type of polyunsaturated fatty acid. Dr. Christopher Turbill will present the research at the Society for Experimental Biology meeting on Monday, June 29. ...> Full Article


Corals stay close to home (6/30/2009)

New DNA analysis reveals that corals are more closely related than previously thought, and these results have significant implications for coral conservation. ...> Full Article


Evolution of a contraceptive for sea lamprey (6/29/2009)

In addition to providing fundamental insights into the early evolution of the estrogen receptor, research by a team at the University of California - San Diego School of Medicine may lead to a contraceptive for female lampreys -- a jawless fish considered an invasive pest species in the Great Lakes region of the United States. This could prove important to the Great Lakes region, where lampreys aggressively consume trout, salmon, sturgeon and other game fish. ...> Full Article


Good males are bad fathers (6/28/2009)

Contrary to predictions, males of high genetic quality are not very successful when it comes to fertilizing eggs. A new study on seed beetles by Swedish and Danish scientists Goran Arnqvist and Trine Bilde shows that when a female mates with several males, the males of low genetic quality are the most successful in fertilizing eggs. The study is published in this week's issue of Science. ...> Full Article


Dolphins get a lift from delta wing technology (6/27/2009)

Dolphins are supremely agile swimmers, but it wasn't clear how their fins help them maneuver though water. Building scale models of whale and dolphins' fins, a team of US scientists has found that some dolphins' fins work just like delta wing aircraft. ...> Full Article


Rhesus monkeys discriminate faces much as humans do (6/27/2009)

Humans' ability to easily distinguish among many faces and recognize people they know goes way, way back, say researchers reporting online on June 25 in Current Biology, a Cell Press publication. That assertion stems from new evidence that, like us, rhesus monkeys tell their friends from foes by picking up on the precise layout of facial features. ...> Full Article


Researchers see evidence of memory in the songbird brain (6/27/2009)

Researchers see evidence of memory in the songbird brainWhen a zebra finch hears a new song from a member of its own species, the experience changes gene expression in its brain in unexpected ways, researchers report. The sequential switching on and off of thousands of genes after a bird hears a new tune offers a new picture of memory in the songbird brain. ...> Full Article


Disappearing dolphins clamour for attention at whale summit (6/26/2009)

Small whales are disappearing from the world's oceans and waterways as they fall victim to fishing gear, pollution and habitat loss -- compounded by a lack of conservation measures such as those developed for great whales, according to a new WWF report. ...> Full Article


Toxic molecule may help birds 'see' north and south (6/25/2009)

Toxic molecule may help birds 'see' north and southResearchers at the University of Illinois report that a toxic molecule known to damage cells and cause disease may also play a pivotal role in bird migration. The molecule, superoxide, is proposed as a key player in the mysterious process that allows birds to "see" Earth's magnetic field. ...> Full Article


Changes in brain architecture may be driven by different cognitive challenges (6/24/2009)

Scientists trying to understand how the brains of animals evolve have found that evolutionary changes in brain structure reflect the types of social interactions and environmental stimuli different species face. The study is the first to compare multiple species of related animals, in this case social wasps. ...> Full Article


Geographic profiling applied to track hunting patterns of white sharks in South Africa (6/24/2009)

Geographic profiling applied to track hunting patterns of white sharks in South AfricaA paper coming out in the Journal of Zoology describes the use of geographic profiling to examine the hunting patterns of white sharks of the coast of South Africa. The study was conducted by scientists at the University of Miami and University of British Columbia, using technology designed to locate criminal offenders of the two-legged variety by Texas State University. ...> Full Article
