Scientists have built a gene expression database of a stag beetle and identified genes important for sex determination and differentiation.
Peacocks' tails, deer antlers and lions manes are all examples of elaborate sex-specific morphological traits in animals. And like a knight wielding twin spears, males of the golden metallic stag beetle, Cyclommatus metallifer, grow mandibles that...
Until a few years ago the Asian bush mosquito, Aedes japonicus, was not yet present in Europe. Now it is spreading its range in several European countries, including Switzerland, Germany and Austria. Ae. japonicus no longer is an exotic guest -- it is here to stay.
Day-biting and highly reproductive
The Asian bush mosquito has a high...
The first-ever record of a tumourous facial swelling found in a fossil has been discovered in the jaw of the dwarf dinosaur Telmatosaurus transsylvanicus, a type of primitive duck-billed dinosaur known as a hadrosaur.
An international group of researchers, including Kate Acheson, a PhD student at the University of Southampton, have documented a type of non-cancerous...
Is honesty really the best policy? Isn't it more beneficial to cheat, if you can get away with it?
A study from the insect world provides a new perspective on honest communication by showing that paper wasps that send dishonest signals are aggressively punished, and the drubbing can have long-term impacts.
"Why don't animals cheat by signaling...
Researchers at the University of Wisconsin-Madison have confirmed that a benign bacterium called Wolbachia pipientis can completely block transmission of Zika virus in Aedes aegypti, the mosquito species responsible for passing the virus to humans.
Matthew Aliota, a scientist at the UW-Madison School of Veterinary Medicine (SVM) and first author of the paper -- published today...
New research shows similarities in the social organisation of bees and mammals, and provides insight into the genetics of social behavior for other animals. These findings, published in PLOS Computational Biology, use sociogenomics -- a field that explores the relationship between social behaviour and the genome -- to show strong similarities in socially genetic circuits...
