- Full-annual-cycle models track migratory bird populations throughout the yearMany birds spend only a few months of the year in their breeding range before leaving to spend the winter in another region or even on another continent, and models that only make use of data from one season may not paint a complete picture. For this reason, researchers have written the first comprehensive review of the different types of full-annual-cycle m […]
- Mediterranean diet cuts heart disease risk by nearly halfAdults who closely followed the Mediterranean diet were 47 percent less likely to develop heart disease over a 10-year period compared to similar adults who did not closely follow the diet, according to a new study.
- Metabolic path to improved biofuel productionResearchers have found a way to increase the production of fuels and other chemicals from biomass fermented by yeast without the need of environmentally harsh pre-treatments or expensive enzyme cocktails.
- Deadly frog fungus dates back to 1880s, studies findA pair of studies show that the deadly fungus Batrachochytrium dendrobatidis, responsible for the extinction of more than 200 amphibian species worldwide, has coexisted harmlessly with animals in Illinois and Korea for more than a century. The research will help biologists better understand the disease caused by Bd, chytridiomycosis, and the conditions under […]
- Direct evidence that drought-weakened Amazonian forests 'inhale less carbon'Direct evidence of the rate at which individual trees in the Amazonian basin 'inhale' carbon from the atmosphere during severe drought has been provided by an international research team. Researchers found that while the rate of photosynthesis was constant among trees on plots unaffected by drought, rates on the six drought-affected plots dropped s […]
