Seeing red
In spring, thoughts turn to sex, and three-spined stickleback females set about finding the most attractive mate. Their method of selection is to choose the male with the most attractive red belly, so it's not surprising that Dr. Victoria Braithwaite (University of Edinburgh) has discovered that female sticklebacks become more sensitive to red... view more...

Identifying Mega-Targets for High-Yield Plant Breeding
Promoting genetic diversity in crops is traditional practice for agriculture professionals, and with today's technology, scientists are able to develop breeding programs with great care for the security of crops. This is particularly important due to the numerous risks the world's food supplies face with the changing climate. view more (2009-02-17)
Conflict over rearing young shapes breeding systems
An article in the October 2006 issue of BioScience, the monthly journal of the American Institute of Biological Sciences (AIBS), describes evidence that conflict between male and female shorebirds over which member of a breeding pair will raise their young has had a profound influence on the evolution of breeding systems in these birds. view more (2006-10-03)
Delayed breeding is not necessarily costly to lifetime reproductive success
Using 24 years of data from the longest-running study of a cooperative bird species on the African continent, researchers at the Universities of Bristol and Cape Town have cast doubt on one of the biggest assumptions in behavioral ecology: that a delayed start to breeding is necessarily costly to reproductive success. view more (2007-04-06)
Symbiotic fungi promote invasion into diverse plant communities (Rudgers et al.)
Populations of several European passerines that winter south of the Sahara have undergone a marked decline. The causes of negative population trends are largely unknown, but ecological conditions during winter in Africa may have carry-over effects during northward spring migration and reproduction. In the January issue of Ecology Letters, Saino,... view more... (2003-12-10)
Females do best if they wait a while
Starting to breed late in life is a bad idea if you want to maximise the number of offspring that you produce-or so the theory goes. view more (2007-04-09)
Parasites might spur evolution of strange amphibian breeding habits
Parasites can decimate amphibian populations, but one University of Georgia researcher believes they might also play a role in spurring the evolution of new and sometimes bizarre breeding strategies. view more (2007-11-15)
Postcode Lottery for Birds
Scientists from the University of East Anglia (UEA) have discovered that it's not only people who can suffer from 'postcode lottery' syndrome, but birds too can have radically different life spans depending on where they live. The research, published today (26 July) in the international journal Nature, shows for the first time that black-tailed... view more... (2001-07-23)
Floating lovers count too — in the health of eagle populations
In a paper from the November issue of The American Naturalist, Vincenzo Penteriani, Fermín Otalora, and Miguel Ferrer, researchers at the Estación Biológica de Doñana (Consejo Superior de Investigaciones Científicas, Spain), focus on the forgotten and invisible side of animal populations-the floaters. Floaters are dispersed individuals who... view more... (2006-11-02)
Study investigates 'divorce' among Galapagos seabirds
Being a devoted husband and father is not enough to keep an avian marriage together for the Nazca booby, a long-lived seabird found in the Galapagos Islands off the coast of Ecuador. view more (2007-06-13)
Sexual reproduction delays aging in a mammalian species
Past research on aging and the life histories of diverse species has shown that sexual reproduction is biologically costly for individuals and tends to decrease lifespan rather than increase it. view more (2006-02-22)
Uncertainty drives the evolution of 'cooperative breeding' in birds
Rather than striking out to start a family of their own, members of some bird species will stick around longer to help a relative raise their young. view more (2007-08-17)
For some species, an upside to inbreeding
Although breeding between close kin is thought to be generally unfavorable from an evolutionary standpoint, in part because harmful mutations are more easily propagated through populations in this way, theory predicts that under some circumstances, the benefits of inbreeding may outweigh the costs. view more (2007-02-06)
Nuclear science for food security
The International Atomic Energy Agency (IAEA) today called for increased investment in a plant breeding technique that could bolster efforts aimed at pulling millions of people out of the hunger trap. view more (2008-12-02)
Lifeline for vultures from breeding centre plan
Conservationists say six major breeding centres will be needed, for three species of vultures, if they are to be saved from extinction in the Indian subcontinent. view more (2004-09-29)
Uncertain rainy days make birds turn to family, Cornell study finds
Rather than striking out to raise their family, members of some bird species cooperate to help raise their siblings, nephews, nieces, cousins -- or even unrelated young. Researchers have long noted which factors lead to these seemingly altruistic decisions, but now for the first time, Cornell researchers have linked a specific environmental factor... view more...

£7.6M awarded to discover how genes interact with each other
The research could ultimately pave the way for plant and animal breeders to reduce the element of chance that currently exists in conventional selective breeding. It may also enable them to re-introduce genes that have been accidentally lost during decades of conventional breeding. view more (1999-12-15)
Tropical winter habitat drives natal dispersal of young migratory birds
A new study by scientists at the Migratory Bird Center at the Smithsonian's National Zoo shows that the factors determining where birds settle and nest in the first breeding season depends on the habitat they used during their first winter in the tropics. view more (2008-02-19)
Glasgow ecologist wins British Ecological Society award
Glasgow University ecologist Dr Hanna Kokko will be awarded the British Ecological Society~s Founders~ Prize at the BES Winter Meeting which will be held at the University of Birmingham on 3-5 January 2001. The prize is awarded every two years to an outstanding ecologist early in their career for making a significant contribution towards the... view more... (2000-12-15)
UK science helps farmers in Africa and India
As the world's attention is focused on issues of aid and trade in developing countries, UK researchers have shown how science can improve the lives of farmers in Africa and Asia. view more (2005-07-06)
