Sep. 20, 2021 Biologists sized up an unlikely natural phenomenon: when parasitism actually causes the number of hosts to increase, an effect known as a hydra effect. A study of common water fleas and their fungal ...
Dec. 4, 2023 Researchers have found the earliest-known fossil mosquito in Lower Cretaceous amber from Lebanon. What's more, the well-preserved insects are two males of the same species with piercing ...

July 13, 2022 Fleas are only a few millimeters in size. But they do have a whole arsenal of defenses -- even against aggressive ...
July 19, 2023 Prey size and risk of predation are strongly related to the medium-sized Daphnia -- a small, planktonic crustacean -- targeted by aquatic insects and fish. This phenotypic plasticity has been shown ...
Jan. 26, 2022 The freshwater aquatic larvae of the Chaoborus midge are the world's only truly planktonic insects, regulating their buoyancy using two pairs of internal air-filled sacs, one in the thorax and ...
Aug. 13, 2021 A team of scientists recently published their findings from a remarkable study involving antimicrobial resistant (AMR) ...
Nov. 2, 2021 The number of wild bees has fallen dramatically since 1990. An expert urges researchers to assume their responsibility and help save the insects who hold the key to upholding human food ...
