Biologists have found that blue tits, great tits and other native birds have learnt to peck away the tips of the galls formed by invading oak gall wasps and eat the juicy larvae inside, which are rich in protein. This helps ...
In the rain forests of the Congo, where mammals and birds are hunted to near-extinction, an impenetrable sound of buzzing insects blankets the atmosphere.
When herbivores such as caterpillars feed, plants may "call for help" by emitting volatiles, which can indirectly help defend the plants. The volatiles recruit parasitoids that infect, consume and kill the herbivores, to ...
In a remarkable piece of detective work, a team of 'retired' CSIRO scientists have revealed the group of artists responsible for the iconic scribbles found on smooth-barked Eucalyptus trees in southeastern Australia.
Fluttering onto a smartphone near you soon, a field guide to the butterflies of Northern California, created by UC Davis students.
In relationships based on mutuality, number of individuals involved can determine rate at which species evolve
(Phys.org)—The relationship between species determines how rapidly they evolve. Parasites and their hosts coevolve more rapidly, and partners in a mutualistic relationship can evolve more slowly. But this view is obviously ...
Eggs of insect pests deposited on plants trigger the production of scents by plants that affect different plant community members probably helping the plant to get rid of the pest before it becomes harmful.
Caterpillars belonging to a species of butterfly previously unknown as far north as Canada have been discovered in Montreal, in a sign that this country's cool climate is warming, researchers said Monday.
(Phys.org) -- When the threat of predators lurks, prey often eat less to avoid being out in the open and vulnerable to attack.
(Phys.org) -- A team of scientists has made a novel discovery that could provide a new strategy for controlling armyworms and other insect crop pests around the globe.
