Fuel-cell technology provides new approach to energy-efficient heating and refrigeration
Fuel cell technology has attracted a lot of attention recently for its potential to revolutionize the transportation sector by decreasing our use of fossil fuels and reducing emissions that contribute to climate change. (more…)
Males that mate more often are more insecure about their social status than those mating less, according to new research on the behaviour of burying beetles.
The study, published in the journal Evolution, provides new evidence that the social sensitivity of male behaviour is linked to how often male beetles mate. (more…)
Researchers at the University of Exeter have found that sexual conflict over mating impacts the parental care behaviour and reproductive productivity of burying beetles.
These beetles have surprisingly complex parental care, similar in form to that provided by birds such as robins or blackbirds, with offspring begging to be fed by touching parents, who respond by regurgitating partially digested food.
Both males and females provide parental care, but females are the primary care givers, as in humans. So anything that affects the ability of females to provide parental care, such as costly mating, is likely to reduce overall reproductive productivity. (more…)
