When thinking about ways to end global hunger, many scholars focus too narrowly on increasing crop yields while overlooking other critical aspects of the food system.
Endangered penguins respond rapidly to changes in local fish numbers, and monitoring them could inform fisheries management and marine conservation.
In Mexicali, Mexico, an uncontrolled epidemic of Rocky Mountain spotted fever, one of the deadliest tickborne diseases in the Americas, has affected more than 1,000 people since 2008. A binational team of researchers led by the University of California, Davis, has conducted the first comprehensive study to examine risk factors for the disease in Mexicali. Researchers examined dogs, ticks, and surveyed households in 200 neighborhoods.
Adopting common business practices, such as robust supply chains, market analysis and rebates, can increase the adoption of improved cookstoves by as much as 50% in rural India, according to a new study led by Duke University researchers. Electric stoves were very popular, highlighting India's need to continue rural electrification.
The University of Wisconsin-Madison's Monica Turner and her team describe what happens when Yellowstone -- adapted to recurring fires every 100 to 300 years -- instead burns twice in fewer than 30 years. Yellowstone as we know it faces an uncertain future, the researchers say, and one of the big questions they hope to answer is whether the forests can recover.
The susceptibility of ecosystems to disruption depends on a lot of factors that can't all be grasped. Ulrich Brose from University of Jena (Germany) has therefore developed a new method that provides good results with only a few information about the properties of predators. The model confirms that a large body mass index between predator and prey creates stable systems. It can also predict which predator species play a key role.
The caterpillars of Lymantria dispar or Gypsy Moth are voracious eaters capable of defoliating entire forests. Sometimes they can even make harm for coniferous forests. Gypsy Moths are widely spread in Europe, Asia and Northern America.
Ivan Nekhaev, a postdoc at St. Petersburg University, studied snails of the genus Boreocingula -- tiny gastropods as small as half a centimeter -- and first discovered that Arctic micromolluscs can show signs of pseudohermaphroditism. Boreocingula martyni adult females grow underdeveloped male genital organs.
Historic climate change events can have a lasting impact on the genetic diversity of a species, reveals a new study on the alpine marmot.
Scientists have developed a new approach to describe the behaviors of microscopic marine larvae, which will improve future predictions of how they disperse and distribute.
