Sep. 19, 2024 Ecologists have long sought clarity on the dietary habits of different animal species. For scientists, it wasn't obvious how herbivores in Yellowstone National Park, who subsist on grasses, wildflowers and trees, could compete for enough of those foods to survive the winter. Over two years, with the aid of cutting-edge molecular biology tools and ...

Sep. 20, 2024 The Colorado River is a vital source of water in the Western United States, providing drinking water for homes and irrigation for farms in seven states, but the basin is under increasing pressure from climate change and drought. A new computational tool may help the region adapt to a complex and uncertain ...

Sep. 20, 2024 Researchers have found microplastics less than 300 m in size in coral skeletons. The team developed a new protocol to extract and detect microplastics and applied it to coral samples from the Gulf of Thailand. The finding may also explain the 'missing plastic problem,' where about 70% of plastic in the oceans cannot be found. The corals may act as a 'sink' for microplastics, absorbing them from ...

Sep. 18, 2024 A study reveals that current methods of designing and evaluating wildlife corridors may not be adequate to ensure wildlife protection, and suggests that Best Management Practices should include analyzing corridors with a smarter and more thorough framework. Researchers tested different wildlife corridor designs against black bear movement data in Florida and found that each achieved very ...

Sep. 19, 2024 Findings suggest that new genes can form by repurposing fragments of ancestral genes while incorporating entirely new coding regions (the protein-coding parts of the DNA). This innovative concept bridges the gap between entirely new gene formation from noncoding regions and the more traditional model in which new functions can arise from duplicated ...

Sep. 17, 2024 Scientists have unravelled a mystery about the disappearance of dwarf hippos and elephants that once roamed the picturesque landscape on the Mediterranean island of Cyprus before palaeolithic humans arrived. Cyprus only had two species of megafauna present during the Late Pleistocene -- the 500-kg dwarf elephant (Palaeoloxodon cypriotes), and the ...

Sep. 19, 2024 Ancient DNA has provided spectacular insights into human history, particularly in Europe and Asia, where researchers have reconstructed the genomes of thousands of people. However, fewer than two dozen ancient genomes have been recovered from southern Africa -- specifically Botswana, South Africa and Zambia -- which has some of the world's ...
