Conservation and immunology of wild seabirds: Vaccinating two birds with one shot
A group of researchers from the University of Barcelona (Spain), the CNRS in Montpellier (France) and Princeton University (USA) report in The American Naturalist that the vaccination of females of a long ...
Far from powerless: Ant larvae cannibalize eggs, are influenced by relatedness and sex
To the casual observer, the colonies of social insects like bees and ants appear to be harmonious societies where individuals work together for the common good. But appearances can be deceiving.
Amazonian bird chicks mimic poisonous caterpillar to avoid detection
Factors that drive sexual traits
Many male animals have multiple displays and behaviours to attract females; and often the larger or greater the better.
Bite to the death: Sugarbag bees launch all-conquering raids
They may be tiny and stingless but there's nothing sweet and innocent about a species of native Sugarbag bee when it goes to war over a coveted honey-filled hive.
Lizards in the Caribbean: How geography influences animal evolution
A new and potentially more revealing way of studying how animal evolution is affected by the geography of climate has been designed by researchers at The University of Nottingham and Harvard University.
Nature collides with James Bond: Newly discovered ant species hides in plain sight
Researchers plan and plot every considerable aspect of their work, but sometimes it's something unexpected and seemingly insignificant that leads to the real discovery. That was the case for Scott Powell, ...
Lizards help us find out which came first: the baby or the egg?
Have you ever wondered why we give birth to live young rather than lay eggs? Scientists have pondered this for a long time and answers have come from an unlikely source: some of Australia's lizards and snakes!
Butterflies switch lifestyles using hormones
Many habitats on Earth change dramatically with the seasons, profoundly affecting food availability, predation pressure and reproductive opportunities for animals living in these seasonal habitats. To survive ...
Why the urge to find 'Nemo' has helped fish diversify
Caring parents foster successful offspring, or so the thinking goes. But for reef fishes, such as Disney's charismatic clownfish, Nemo, the effects of parental care stretch right across evolutionary time ...
100 million year study shows a sheltered start breeds evolutionary success
Research into reef fish species diversity will provide conservationists with new information to protect the Great Barrier Reef.
Sibling cooperation in earwig families gives clues to early evolution of social behavior
Looking at the question of how social behavior has developed over the course of evolution, scientists from the universities in Mainz and Basel have gained new insights from the study of earwigs. "Young earwig ...
Rock-paper-scissors model helps researchers demonstrate benefits of high mutation rates
For most people, rock-paper-scissors is a game used to settle disputes on the playground. For biologists, however, it is a powerful guide for understanding the key role mutation plays in the evolution of ...
Tiny male spiders can get a leg over—as long as they're picky
Males will mate with anything. Well, that is the general view, one that exists because of a simple biological underpinning: females are reproductively limited by costly gestation, while males are only limited ...
Are plants more intelligent than we assumed?
Plants are also able to make complex decisions. At least this is what scientists from the Helmholtz Center for Environmental Research (UFZ) and the University of Göttingen have concluded from their investigations ...
