New research indicates that the common fruit fly can travel tens of kilometers in a single flight when in search of food.
Praying mantises are bizarre insects, yet many aspects of their biology remain unknown. Meanwhile, scientists from the Ruhr-University and the Bavarian State Collection of Zoology discovered that females of a South American species protrude a Y-shaped organ on their backs to release pheromones and attract males. Found in none of the over 2,500 species of praying mantises worldwide, the behaviour is reported for the first time in the peer-reviewed scientific Journal of Orthoptera Research.
Dietary sugars and gut microbes play a key role in promoting malaria parasite infection in mosquitoes. Researchers in China have uncovered evidence that mosquitoes fed a sugar diet show an increased abundance of the bacterial species Asaia bogorensis, which enhances parasite infection by raising the gut pH level. The study appears April 20 in the journal Cell Reports.
"Generalist" plants and pollinators play a crucial role in maintaining biodiversity and may also serve as buffers against some impacts of climate change, finds new University of Colorado Boulder research. The findings, published this month in Ecology, provide valuable insights for prioritizing the conservation of species that contribute to the strength of ecological communities.
Researchers from the Max Planck Institute for Chemical Ecology and the University of Mainz, together with an international team, showed that the genome of symbiotic bacteria of beewolves is in the process of being reduced to their important protective function: the production of antibiotics. The bacterial genome is of great interest for understanding genome erosion and elucidating how the cooperation between bacteria and their host insects has evolved over long periods of time.
Researchers from Tokyo Metropolitan University and Hosei University have discovered a new species of large, tropical centipede of genus Scolopendra in Okinawa and Taiwan. It is only the third amphibious centipede identified in the world, and is the largest in the region, 20 cm long and nearly 2 cm thick. It is also the first new centipede to be identified in Japan in 143 years, testament to the incredible biodiversity of the Ryukyu Archipelago.
Diapause is a phenomenon in which animals and insects foresee changes in the environment and actively reduce metabolism, or halt regular differentiation and development. By knocking out genes that allow the silkworm to detect temperature, researchers found that the silk moth diapause changes from temperature to day length. This is not only valuable for the molecular mechanism in the environmental response, but also an important finding in exploring the process of domestication of silk moths.
Named after the coronavirus, a new caddisfly species, found in Kosovo, highlights the quarantine time during which it was described, but also refers figuratively to another 'silent' pandemic impacting the freshwater organisms in Kosovo's rivers. Pollution, degradation of freshwater habitats and the activity of hydropower plants have been compromising these ecosystems. The team of scientists, led by Professor Halil Ibrahimi from the University of Prishtina, described the new species in the open-access Biodiversity Data Journal.
Spiders are master builders, expertly weaving strands of silk into intricate 3D webs. If humans could enter the spider's world, they could learn about web construction, arachnid behavior and more. Now, scientists report they have translated the complex structure of a web into music, which could have applications ranging from better 3D printers, to cross-species communication and otherworldly musical compositions. The researchers will present their results today at ACS Spring 2021.
"Invasive Species in Forests and Rangelands of the United States: A Comprehensive Science Synthesis for the United States Forest Sector," was recently released as an open-access book by Springer Nature. The assessment serves as a one-stop resource for land managers who are looking for information on the invasive species that are already affecting the landscape, the species that may threaten the landscape, and what is known about control of invasive species.
