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 ...
Squabbling meerkats make better decisions
Conflicting interests within a group can lead to better collective decisions – if you're a social animal such as a meerkat – according to new research by a team of biologists and political scientists ...
New research reveals unique monogamous behaviour in sparrows
Geography might reveal the answer to why some species vary in promiscuity, according to new research by Queen's Professor Fran Bonier (Biology). She discovered sparrows are more promiscuous at higher latitudes and are less ...
Animal personalities are more like humans than first thought
(Phys.org) —A Deakin University study has found for the first time that, just like humans, un-predictability is also a consistent behavioural trait in the animal world.
