The dramatic difference in gonad size between honey bee queens and their female workers in response to their distinct diets requires the switching on of a specific genetic program, according to a new study publishing March 21 in open-access journal PLOS Biology by Annika Roth and Martin Beye of Heinrich-Heine University in Dusseldorf and colleagues. The finding may aid analysis of the interplay of genes and nutrition that drive caste dimorphism in honey bees.
A growing number of pet owners is interested in feeding their pets plant-based diets.
Bromethalin, a common rat poison, is the agent responsible for a neurological disease that has sickened or killed birds from a popular flock of naturalized parrots that reside primarily in the Telegraph Hill area in north San Francisco.
A study into the effectiveness of disinfecting birds' nests, carried out by the University of Kent, has led to a breakthrough in the understanding of biosecuity measures for the endangered echo parakeet in Mauritius. The research team found that annual disinfection of parakeet nest sites prior to the breeding season, intended to reduce the spread of infectious disease in endangered parrot species, didn't have the impact conservationists expected leading to recommendation for a different approach.
As states around the country move to stiffen punishments for animal cruelty, Michigan State University researchers have found a correlation between the types of animal abuse committed and the perpetrator's relationship to an animal and its owner.
The statement is a bold one, especially as wolves have received a lot of negative attention in recent years. A recent study conducted by behavioral researchers at Vetmeduni Vienna, however, shows that dogs and wolves both work equally well with humans, albeit in different ways. The allegedly unequal brothers are thus much more similar than often assumed.
Narwhals -- enigmatic arctic whales known for their sword-like tusk -- spend over half their time diving to find food but are also able to last up to three days without a meal, according to a study by Manh Cuong Ngô and colleagues from the University of Copenhagen in Denmark, published in PLOS Computational Biology.
New study on an owl's re-colonization of northern Switzerland.
Planthopper bugs may be small, but they attract mates from afar by sending vibrational calls along plant stems and leaves using fast, rhythmic motions of their abdomen. In a new study publishing March 12 in the open-access journal PLOS Biology, researchers at the University of Oxford show how a newly discovered 'snapping organ' enables courting bugs of both sexes to produce this shaking motion through a combination of muscle action and elastic recoil.
New research publishing March 12 in the open-access journal PLOS Biology reveals that human threats -- like hunting and land clearing -- are extensive across thousands of species' habitats, severely limiting the area they can survive in.
