Russian scientists studied the trends in the evolution of amino acid sequences of proteins in vertebrates and insects. External factors can be considered as a reason for positive selection affecting genomic positions and serve as an essential aspect of the rapid evolution. But the effect of epistasis is manifested in positions under negative selection, as a result of which substitutions occur less often in them - they evolve more slowly.
New research by the University of Kent's Durrell Institute of Conservation and Ecology (DICE) has demonstrated a clear fluctuation in the trade of wildmeat in and around the High Niger National Park in Guinea, West Africa.
Research has found a proposal to regulate mining of Indigenous lands in Brazil's Amazon rainforest could affect more than 863,000 square kilometres of forest and harm the nation's economy.
Researchers have identified an invasive blood-sucking parasite on mud shrimp in the waters of British Columbia's Calvert Island. The discovery represents the northern-most record of the parasite on the West Coast and is likely an indication of its ability to spread without human transport.
Preserving terrestrial biodiversity requires more ambitious land-conservation targets to be established and met. At the same time, 'bending the curve' on biodiversity loss needs more efficient food production, and healthier and less wasteful consumption and trade. If undertaken with 'unprecedented ambition and coordination,' these efforts provide an opportunity to reverse terrestrial biodiversity loss by 2050.
Freshwater turtles may have a role in regulating water quality in river systems by scavenging fish carcasses, suggests a study of Emydura macquarii, a vulnerable freshwater turtle species found in Australia. The findings are published in Scientific Reports.
Multi-stakeholder collaboration is key for the adoption of molecular approaches that can facilitate accurate, cheaper and faster monitoring of marine ecosystems.
A University of Arkansas biologist is part of an international team of researchers is building a volunteer network of citizen scientists to help monitor the abundance of dragonflies and damselflies.
During a research stay in the highlands of Colombia conducted as part of her doctorate, Charlotte Hopfe, PhD student at the University of Bayreuth, has discovered and zoologically described a new species of spider.
Researchers at the Western Pacific Tropical Research Center at the University of Guam have documented what biologists call a "host shift" of the coconut rhinoceros beetle in Guam. The beetle, first documented as an invasive species in Guam in 2007, has been devastating the island's ubiquitous coconut trees and is now also burrowing into Guam's endangered native cycad tree, Cycas micronesica.
