Having more flowers and maintaining diverse bee communities could help reduce the spread of bee parasites, according to a new study.
Various forms of mercury are released naturally by volcanoes and weathering of rocks and soil. Human activities, such as mining or burning fossil fuels, can also release the element into the environment, where aquatic microbes can convert it into the toxic form, methylmercury. Now, researchers reporting in ACS' Environmental Science & Technology have shown that dragonfly larvae, collected from national parks as part of a citizen-scientist engagement program, can serve as sentinels for mercury bioaccumulation.
Research confirms dragonfly larvae as "biosentinels" to indicate mercury pollution and presents the first-ever survey of mercury pollution in the U.S. National Park System.
New research, published in Environmental Toxicology and Chemistry, sheds light on the effects the synthetic estrogens commonly found in birth control pills have on leeches.
Biodiversity and thus the state of river ecosystems can now be predicted by combining environmental DNA with hydrological methods, researchers from the University of Zurich and Eawag have found. Using the river Thur as an example, the approach allows areas requiring conservation to be identified in order to initiate protective measures.
Whether they travel only a few metres or tens of kilometres to a new host tree, female pine beetles use different strategies to find success--with major negative consequences for pine trees, according to new research by University of Alberta biologists.
Top predators dinosaurs like the Allosaurus and Ceratosaurus devouring dinosaur remains isn't all that surprising, but the smaller creatures feasting on dinosaur remains may just give us a more complete picture of what life was like at Mygatt-Moore Quarry outside Fruita, Colorado 152 million years ago. A new study out in PeerJ on Wednesday July 15th, 2020 authored by Museums of Western Colorado's Paleontologist Dr. Julia McHugh, looks at the insect species who feasted on decaying dinosaurs back in the Jurassic period.
Bed bug infestations can modify the home microbiome, according to a new NC State study. When bed bugs are eradicated, home microbiomes return to normal.
Flies are able to right themselves very quickly when taking off from an upside-down position. Scientists from the CNRS and from The Institute of Movement Science (ISM) at Aix-Marseille Université studying this phenomenon discovered the surprising way these insects begin by turning their bodies before their heads on take-off. The research will be published on 15 July 2020 in the Journal of Experimental Biology.
"Nix has great potential for developing mosquito control strategies to reduce vector populations through female-to-male sex conversion, or to aid in the Sterile Insect Technique, which requires releasing only nonbiting males," said James Biedler, a research scientist in the Tu lab.
