The compounds behind the perfumes and colognes you enjoy have been eliciting olfactory excitement since dinosaurs walked the Earth amid the first appearance of flowering plants, new research reveals.
A closer look into mosquitoes from three separate site in the Caucasus allowed for Russian scientist Dr. Mukhamed Karmokov to not only study the evolution of a curious group of species, but also provide a brand new insight into the role of the Caucasian region from an evolutionary perspective. His paper, which demonstrates how the mountain simultaneously unifies and divides its fauna is published in the open access journal Comparative Cytogenetics.
A new clinical trial shows that consuming crickets can help support the growth of beneficial gut bacteria and that eating crickets is not only safe at high doses but may also reduce inflammation in the body.
A study from the Faculty of Biology and the Biodiversity Research Institute of the University of Barcelona (IRBio-UB) analysed how water macroinvertebrate species, such as beetles, mosquitos and dragonflies, evolved and diversified since their beginnings. With the analysis of the ecological features of about 6,600 European species, researchers rebuilt the functional space they occupy.
The future of Arctic mosquitoes (Aedes nigripes) in western Greenland depends on aquatic habitat and access to blood meals, according to a Dartmouth study. The study found that female mosquitoes carrying eggs were most abundant near ponds, especially in areas frequented by animals such as caribou, birds and the Arctic hare. Published in Ecosphere, the findings provide new insight into mosquito population dynamics. The rapid rate of environmental changes in the Arctic are impacting aquatic habitats and wildlife that mosquitoes depend on for blood meals.
A new study reveals that all insects use specialized odorant receptors that enable them to detect and pursue mates, identify enemies, find food and -- unfortunately for humans -- spread disease. This puts to rest a recent hypothesis that only some insects evolved the ability to detect airborne odors as an adaptation to flight, the researchers said.
The textbook approach to managing disease outbreaks focuses on three factors -- pathogen, host, and environment--but it leaves out one critical component in the case of afflictions such as Zika, malaria, and Lyme: the insect or arthropod responsible for transmission to humans. A new report in the Annals of the Entomological Society of America proposes a new version of the classic 'epidemiologic triad' that better reflects the complexities of managing vector-borne diseases.
Various fungi are known to infect insects and alter their behavior, presumably to assist in spreading fungal spores as widely as possible. But little is known about how the fungi affect behavior. UC Berkeley scientists have now found a fungus that infects the common lab fly, Drosophila melanogaster, providing a model in which to explore behavior-manipulating fungi. They found that the fungus invades the nervous system first while slowly eating the fly's fat and organs.
Scientists recently discovered the aptly named peacock jumping spiders have the color vision needed to appreciate the male's gaudy display. Now biologists at the University of Cincinnati are studying whether that ability translates to the more humdrum-looking wolf spiders that are muted browns and tans instead of electric blue, fiery orange and stoplight red.
A new species of beetle with remarkable genitalia that hint at a curious evolutionary 'sexual arms race' has been described from Malaysian Borneo. The new insect was named after actress and biologist Isabella Rossellini in honour of her online series and stage shows about animal reproduction. Scientists Menno Schilthuizen, Iva Njunjic, and Michel Perreau described the new curious round fungus beetle in the open access journal ZooKeys.
