Sex is costly for insects. It uses up resources such as water, energy and time. Some species, like bush crickets, can ejaculate as much as a quarter of their body weight. In others, like one species of fruit fly, their sperm ...
Sage grouse have a vast network of mating grounds in the U.S. West akin to interconnected regional airport hubs that the imperiled species is using to maintain genetic diversity across its entire range, a DNA study has revealed.
Same-sex mating behaviour amongst male insects is much more likely to be due to incompetence, than sexual preference, male-male competition or evolutionary motivation—according to new research from the University of East ...
"Patient zero" isn't entirely to blame when an infection takes root in a population. According to Rice University scientists, social context in the community has a lot to do with how a disease spreads.
A researcher from Florida Atlantic University is the first to document that two genetically distinct species of guenon monkeys inhabiting Gombe National Park in Tanzania, Africa, have been successfully mating and producing ...
