A new study from the University of Helsinki using miniaturized satellite-based tags revealed that during drier periods desert bats must fly further and longer to fulfil their nightly needs. According to researchers this signals their struggle in facing dry periods.
When Earth's species were rapidly diversifying nearly 500 million years ago, that evolution was driven by complex factors including global cooling, more oxygen in the atmosphere, and more nutrients in the oceans. But it took a combination of many global environmental and tectonic changes occurring simultaneously and combining like building blocks to produce rapid diversification into new species, according to a new study by Dr. Alycia Stigall, Professor of Geological Sciences at Ohio University.
Scientists have recovered the first genetic data from an extinct bird in the Caribbean, thanks to the remarkably preserved bones of a Creighton's caracara from a flooded sinkhole on Great Abaco Island.
Freshwater wetlands from Georgia to New York are home to a previously unrecognized species of medicinal leech, according to scientists at the Smithsonian's National Museum of National History. The new species was first identified from specimens collected in southern Maryland less than 50 miles from Washington, D.C., prompting a search through marshes and museum collections that revealed that the leech has long occupied a range that stretches throughout the eastern United States.
An unprecedented survey has revealed the loss of about 85 percent of historical tidal wetlands in California, Oregon, and Washington. The report, published today in PLOS ONE, also highlights forgotten estuary acreage that might now be targeted for restoration.
For their 19-year study, UC Davis scientists dug roughly 6 feet down to compare soil carbon changes in different cropping systems. They found that compost is a key to storing carbon, a strategy for offsetting CO2 emissions.
The diversity and ecology of African parasitoid wasps was studied for over a year during a project run by the Biodiversity Unit of the University of Turku in Finland. Parasitoid wasps are one of the animal groups that are the most rich in species. However, the tropical species are still very poorly known. Understanding the diversity of parasitoid wasps inhabiting rainforests is important, because tropical biodiversity is dwindling at an accelerating rate.
Evolutionary biologists from Konstanz analyze the role of microRNAs in the evolution of new species.
Researchers have used artificial intelligence to make new discoveries, and confirm old ones, about one of nature's best-known mimics, opening up whole new directions of research in evolutionary biology.
Numerous large mammals have been documented with video traps on Mount Kilimanjaro by a research group of Würzburg University. The protected areas of the mountain are of tremendous importance for the biodiversity of this animal group.
