A long-term study on cycads in Guam has revealed how rapidly invasive species devastated the native Cycas micronesica species and the key factors that have influenced the plant's mortality. The research -- conducted by the Western Pacific Tropical Research Center at the University of Guam and the College of Micronesia-FSM -- is published in the May 2020 issue of Diversity, a peer-reviewed journal published by MDPI.
A comprehensive study on a group of unique ectoparasitic fungi associated with insects and other arthropods in Belgium and the Netherlands was published in the open-access, peer-reviewed scholarly journal MycoKeys. In their paper, the scientists provide identification details about a total of 140 species, including nine species that represent new country records and two species new to science, with one of them named after the 2020 quarantine period, imposed to curb the COVID-19 pandemic.
Some prey species can escape from inside a predator after a successful attack. Kobe University ecologist Sugiura Shinji has found that the aquatic beetle Regimbartia attenuata can actively escape from the vent of the frog Pelophylax nigromaculatus via the digestive system. This is the first time that research has documented the active escape of prey from the body of a predator after being eaten.
A new study confirms that while the eastern and western butterflies fly differently, they are genetically the same. The journal Molecular Ecology published the findings, led by evolutionary biologists at Emory University.
Buzzing by bees during flower pollination is significantly more powerful than that used for defense or flight, according to a new study from experts at the University of Stirling.
Research gives possible answers to increase pollinator populations on farms.
A pair of researchers at the University of California, Riverside, has used machine learning to understand what a chemical smells like -- a research breakthrough with potential applications in the food flavor and fragrance industries.
Crop yields for apples, cherries and blueberries across the United States are being reduced by a lack of pollinators, according to Rutgers-led research, the most comprehensive study of its kind to date. Most of the world's crops depend on honeybees and wild bees for pollination, so declines in both managed and wild bee populations raise concerns about food security, notes the study in the journal Proceedings of the Royal Society B: Biological Sciences.
The biomass of small animals that decompose plants in the soil and thus maintain its fertility is declining both as a result of climate change and over-intensive cultivation. To their surprise, however, scientists from the UFZ have discovered that this effect occurs in two different ways: while the changing climate reduces the body size of the organisms, cultivation reduces their frequency. Even by farming organically, it is not possible to counteract all negative consequences of climate change.
Following a decade-long effort, scientists have mapped out the genome of an aphid-like pest capable of decimating vineyards. In so doing, they have discovered how it spreads -- and potentially how to stop it.
