Love calls from the bottom
Some men send flowers, others send chocolates. But one species of fish has a rather unusual method of seducing the opposite sex. Researchers at the Centre of Marine Science, University of Algarve, Portugal, have been studying how the peacock blenny fish secretes pheromones – chemical ‘love’ signals – from an anal gland. view more (2002-04-04)
Duke study examines evolutionary consequences of bluebird aggression
In findings that may offer insight into how evolution operates, a Duke University evolutionary ecologist reported evidence that aggressive male western bluebirds out-compete less aggressive males for preferred breeding territories. view more (2006-04-13)
Savanna habitat drives birds, and perhaps others, to cooperative breeding
Delaying having kids to help raise the offspring of others seems like a bad choice if you want to reproduce, but many African starlings have adopted this strategy to deal with the unpredictable climate of their savanna habitats. view more (2007-08-17)
Analysis of fresh strawberries reveals consumer preferences
Fresh strawberries. Just the mention of this iconic spring and early summer fruit can elicit mouthwatering memories of shortcake, fruity drinks and sweet desserts. view more (2009-02-27)
Toad tadpoles and the 'Laurel and Hardy' effect
Research at the University of Kent has revealed a remarkable phenomenon among tadpoles of the Mallorcan midwife toad, one of Europe's most threatened species. The researchers, from the University's Durrell Institute for Conservation and Ecology, (DICE) have discovered that the toad tadpoles can change shape when they smell snakes swimming nearby.... view more...

Upland birds in peril from climate change
New evidence suggests that rarely studied upland birds may be as vulnerable as songbirds to climate change. view more (2005-02-01)
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)
Does a producer benefit from research?
ISAE Helsinki 2004 Information bulletin August 4, 2004 Does a producer benefit from research? In the view of professor Per Jensen, an ethologist at Linköping University in Sweden and one of the world's leading experts on animal behaviour, Nordic animal welfare research is of a high standard and is focused on scientifically relevant issues.... view more...

UCR researchers develop genetic map for cowpea, accelerating development of new varieties
Cowpea, a protein-rich legume crop, is immensely important in many parts of the world, particularly drought-prone regions of Africa and Asia, where it plays a central role in the diet and economy of hundreds of millions of people. view more (2009-10-14)
New study suggests link between environmental toxins and early onset puberty in girls
Although scientists have speculated over the negative effects of environmental toxins for years, new data suggest that certain environmental toxins may disrupt the normal growth and hormonal development of girls. view more (2008-02-07)
Team finds an economical way to boost the vitamin A content of maize
A team of plant geneticists and crop scientists has pioneered an economical approach to the selective breeding of maize that can boost levels of provitamin A, the precursors that are converted to vitamin A upon consumption. view more (2008-01-18)
Huddling and a drop in metabolism allow penguins to survive the South Pole cold
March of the Penguins, the Oscar® winning documentary, showed how the emperor penguins endure their incubation and fast for four dark and bitterly cold months each year. The tight huddling among these South Pole penguins is a key energy-saving mechanism that allows them to endure their extremely harsh conditions. view more (2007-02-01)
Ancient genes used to produce salt-tolerant wheat
Two recently discovered genes from an ancient wheat variety have led to a major advance in breeding new salt-tolerant varieties. view more (2007-02-05)
Biologists find jumbo welfare problems in zoo elephants
Zoo elephants are stressed and unhealthy, with a massively reduced life expectancy, according to Oxford University biologists Dr Ros Clubb and Dr Georgia Mason. In an independent report released today [Wednesday 23 October], they call for zoos to stop importing and breeding elephants until they can prove that their welfare problems are completely... view more...

New map of variation in maize genetics holds promise for developing new varieties
A new study of maize has identified thousands of diverse genes in genetically inaccessible portions of the genome. New techniques may allow breeders and researchers to use this genetic variation to identify desirable traits and create new varieties that were not easily possible before. view more (2009-11-20)
Gene Revolution Reaches The Poorest Farmers In India
It's the news they have all been waiting for. After years of living under the threat of another devastating epidemic of downy mildew, a disease similar to that which caused the Irish potato famine, India's poorest farmers have been offered a lifeline in the form of a new disease-resistant hybrid. The hybrid has been produced in record time using... view more... (2005-02-25)
Challenges remain in reintroducing American chestnut
Researchers have developed a breed of American chestnut that is resistant to the fungal blight that decimated its population in the early 1900s. view more (2007-08-23)
Climate change creates dramatic decline in red-winged black bird population
Global warming strikes again. A University of Illinois researcher reports that a red-winged black bird population in Ontario, Canada has decreased by 50 percent since 1972. view more (2006-11-14)
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)
Insomniac flies resemble sleep-deprived humans
Researchers at Washington University School of Medicine in St. Louis have created a line of fruit flies that may someday help shed light on the mechanisms that cause insomnia in humans. view more (2009-06-03)
