A mating strategy among redback spiders where males seek out immature females appears to benefit both sexes, a new U of T Scarborough study has found.
A protein transferred from male to female mosquitoes during sex influences female mating behavior -- a phenomenon that could be exploited to limit the spread of mosquito-borne illnesses like Zika and dengue.
Butterflies fly during the day while moths travel at night - or so you might think. In reality, their behavior is much more complicated. A new Florida Museum of Natural History study offers the first comprehensive overview of the surprisingly complex question of when butterflies and moths are active.
The honey bee gut is colonized by specialized bacteria that help digest components of the floral pollen diet and produce molecules that likely promote bee health. In a study publishing Dec. 12, in the open access journal PLOS Biology, a group of researchers led by Philipp Engel at the University of Lausanne and ETH Zürich, Switzerland, have uncovered which bacterial species perform which specific digestive functions in the bee gut.
Farmers are stuck. Western corn rootworm can destroy cornfields -- and profits -- but populations of the 'billion-dollar bug' have stopped responding to insecticides and the genetically modified corn hybrids designed to resist insect attacks. But there may be hope. In a new study, University of Illinois researchers uncover the genetic basis of resistance to western corn rootworm, paving the way for development of non-GM corn hybrids that can withstand the worm.
In sports, sometimes a player has to take one for the team. The same appears to be true in the plant world, where reduced individual growth can benefit the broader community.
The first complete bee census, led by Michigan State University scientists, confirmed a new species and revealed that the actual number of bee species in Michigan exceeded earlier estimates.
As part of a tropical biodiversity field course for citizen scientists initiated by the new organization called 'Taxon Expeditions,' a group of citizen scientists have discovered six new species of beetles in Borneo. The first three of these are published today in the open-access Biodiversity Data Journal.
This fall, the California Academy of Sciences partnered with The Habitat Penang Hill and colleagues to conduct a rainforest survey on Malaysia's island state of Penang. A 117-member team documented flora and fauna from the tops of trees to the dark reaches of caves and discovered several species previously unknown to science living just miles from a major metropolis. Survey results will contribute to this ancient rainforest's nomination as a UNESCO biosphere reserve.
The structure of the sound generators in the wings of male bush-crickets is critical for producing tonality within the long-range mating calls that attract distant females, a major new study has shown.
