A researcher at Washington University in St. Louis travels the Americas, collecting feces from nonhuman primates to determine the risk of Zika reservoirs.
A new paper by an international team of researchers argues that decision-makers and fishing organizations must recognize the growing role of recreational fishing and the potential pressures it places on fish stocks.
The bird's trek between its breeding grounds in the central and western boreal forest of North America and its winter home in the Amazon Basin is one of the longest songbird migrations recorded. Describing a route arcing across North America and including a transoceanic flight to South America, the study confirms an epic migration journey that scientists had long suspected but not yet proved. Tracking their route is key to solving the birds' decline.
Blackpoll warblers that breed in western North America may migrate up to 12,400 miles roundtrip each year, some crossing the entire North American continent before making a nonstop trans-ocean flight of up to four days to South America. Now a new study led by first author Bill DeLuca at the University of Massachusetts Amherst and project lead Ryan Norris at the University of Guelph, Ontario offers details of the feat.
A growing number of pet owners is interested in feeding their pets plant-based diets.
Amidst worldwide talks about 'Insectageddon': the extinction of 40 percent of the world's insects, according to a recent scientific review, a response was published in the open-access journal Rethinking Ecology. Its authors point out major flaws in the earlier study: query- and geographically biased summaries; mismatch between objectives and cited literature; and misuse of existing conservation data. Instead of serving as a wake-up call, those would rather compromise the credibility of conservation science, they warn.
A newly discovered parasitic cycle, in which ocean bacteria keep phytoplankton on an energy-sapping treadmill of nutrient detoxification, may offer a preview of what further ocean warming will bring.
Bromethalin, a common rat poison, is the agent responsible for a neurological disease that has sickened or killed birds from a popular flock of naturalized parrots that reside primarily in the Telegraph Hill area in north San Francisco.
A study into the effectiveness of disinfecting birds' nests, carried out by the University of Kent, has led to a breakthrough in the understanding of biosecuity measures for the endangered echo parakeet in Mauritius. The research team found that annual disinfection of parakeet nest sites prior to the breeding season, intended to reduce the spread of infectious disease in endangered parrot species, didn't have the impact conservationists expected leading to recommendation for a different approach.
An EPFL study has showed that until now, scientists have been substantially underestimating how quickly gases are exchanged between mountain streams and the atmosphere. Based on research in the Swiss cantons of Vaud and Valais, an EPFL laboratory has shed new light on the role of mountain streams to emit greenhouse gases.
