Improved estimates of population extinction risk (Harding and McNamara)
An important application of theoretical ecology is in estimation of species extinction risk. Extinction models guide the selection of management regimes for endangered species. Two vital parameters in these models are the mean population growth rate and its variance. However, empirical data on population growth are rarely perfect, but are... view more... (2003-12-10)
Village bird study highlights loss of wildlife knowledge from one
Our ability to conserve and protect wildlife is at risk because we are unable to accurately gauge how our environment is changing over time, says new research out today in Conservation Letters. view more (2009-02-13)
Crane hatching marks a first for Smithsonian's National Zoo
Smithsonian's National Zoo has announced a first in its 118-year history — the hatching of a rare wattled crane chick. view more (2007-04-23)
Controlling parasite burdens in wild red grouse Lagopus lagopus scoticus through the indirect application of anthelmintic
In an article published today in issue 6 of the Journal of Applied Ecology, Dave Newborn of The Game Conservancy Trust explains the practical implications of a four-year heather moorland experiment that aimed to reduce the impact of parasitic worms on wild red grouse populations. view more (2002-11-26)
June Issue
Lasform - building aircraft parts from powder A new process for producing high-tech titanium components for the aerospace industry, using laser forming technology and powdered titanium, could help to reduce production costs for prototype parts. p.328 view more (1999-06-01)
Discovery opens door for drugs to fight bird flu, other influenza epidemics
Researchers at Rutgers University and The University of Texas at Austin have reported a discovery that could help scientists develop drugs to fight the much-feared bird flu and other virulent strains of influenza. view more (2008-08-26)
Humans lend a hand to critically endangered waterbird
Human impact on one of the world's most threatened bird species can be beneficial rather than destructive - and could even save it from extinction - according to counterintuitive new findings by the University of East Anglia (UEA). view more (2009-07-27)
Geneticists at the American Museum of Natural History trace the evolution of St. Louis encephalitis
Before West Nile virus arrived in this country, we had (and still have) a home-grown relative of this pathogen. An epidemic of unknown origin exploded around St. Louis, Missouri in the autumn of 1933, a disease that is now known to be transmitted by mosquitoes from birds to people. view more (2008-05-16)
Smithsonian's National Zoo researchers use electronic eggs to help save threatened species
This is an important summer for kori bustards at the Smithsonian's National Zoo. Four chicks of this threatened African bird have hatched in June and July. view more (2007-07-27)
Mean Population Size Increases with Diversity
A long-standing debate in ecology has been the effect of diversity on the temporal stability of biological systems. Ecological theory predicts that the stability of populations should decline as community diversity increases, in part, because population size is assumed to decline with community richness. In the February issue of Ecology Letters,... view more... (2003-01-28)
Scientists explore chicken genome to reduce animal testing
Cultured chicken cells and fertilised eggs could soon replace mice in a range of laboratory experiments, according to British scientists involved in a major new research project announced today. Scientists, from Nottingham and Dundee Universities, UMIST and the Roslin Institute, are planning to put together a chicken 'gene catalogue' that will... view more... (2001-10-12)
Museum-fueled global study shows you can't judge biodiversity by its bird
The canary in the coal mine, the supposed harbinger of threat for all those around it, isn't as true as it seemed for biodiversity conservation, according to a sweeping study in which a Michigan State University ornithologist participated. view more (2006-11-02)
Risk threshold of daily alcohol intake and drinking duration in liver injury?
Alcoholic threshold effect rather than a dose-response effect on mortality from alcohol-related liver injury. Alcohol intake, rather than the type of alcoholic beverage, was more significant to liver injury. view more (2008-05-21)
Aesop's fable 'the crow and the pitcher' more fact than fiction
In Aesop's fable 'The crow and the pitcher' a thirsty crow uses stones to raise the level of water in a pitcher to quench its thirst. view more (2009-08-07)
Elvis the mystery bird has searchers scouring Arkansas habitats for signs of roosts, nests or stripped bark
Elvis. That is the nickname that Larry Mallard, refuge manager for the White River National Wildlife Refuge in southeastern Arkansas, uses for the ivory-billed woodpecker (Campephilus principalis), now being sought in Mallard's woods by Cornell Lab of Ornithology staffers and volunteers. view more (2005-12-27)
Seeing magnetic fields
It has long been known that migratory birds can make use of the earth's magnetic fields to navigate. Birds read the angle that magnetic fields create on the ground and thereby determine how far north or south they are of the magnetic equator and the magnetic pole. But how do they do this? Is there some unknown "magnetic sense"? It seems... view more... (2004-02-23)
NIH scientists target future pandemic strains of H5N1 avian influenza
Preparing vaccines and therapeutics that target a future mutant strain of H5N1 influenza virus sounds like science fiction, but it may be possible, according to a team of scientists at the National Institute of Allergy and Infectious Diseases (NIAID), a component of the National Institutes of Health (NIH), and a collaborator at Emory University... view more...

Birds migrate together at night in dispersed flocks, new study indicates
A new analysis indicates that birds don't fly alone when migrating at night. Some birds, at least, keep together on their migratory journeys, flying in tandem even when they are 200 meters or more apart. view more (2008-07-08)
Battling bird flu by the numbers
A pair of Los Alamos National Laboratory researchers have developed a mathematical tool that could help health experts and crisis managers determine in real time whether an emerging infectious disease such as avian influenza H5N1 is poised to spread globally. view more (2008-05-28)
Twins have lower risk of suicide than general population
Twins have a lower risk of suicide compared with the general population, concludes a study in this week’s BMJ. view more (2003-08-12)
