UCSB researchers collaborate to track commercial fishing worldwide in real time.
The wetlands in and around Chicago are overwhelmingly invaded by non-native plants, according to a new study by University of Illinois researchers. The study, which pulls together species occurrence data from over 2,000 wetlands in the urban region, is the first to describe wetland invasion patterns on such a large scale in the Chicagoland area.
Genetic analysis by UC Davis showed about one-third of endangered delta smelt were misidentified in surveys of the Yolo Bypass. Their study found that genetic tools can be a powerful complement to visual identification of endangered fish.
A study conducted in São Paulo, Southern Hemisphere's biggest city, shows that mosquitoes belonging to vector species make up for seven out of the eight most common species found in municipal parks; adapted to urban environment, they benefit from the fragmentation of green areas, a process which leads to the extinction of wild species.
Research published in Science today overturns a long-held assumption that Przewalski's horses, native to the Eurasian steppes, are the last wild horse species on Earth
Humans have been fishing the seas for over 42,000 years. However, the global footprint of fishing was poorly understood -- until now. A new study published today in Science illuminates the extent of global fishing -- down to individual vessel movements and hourly activity -- and finds that fishing occurs in over 55 percent of the world's oceans. By revealing where and when fishing occurs, the findings open an unprecedented gateway for improved ocean management.
Bats are known to harbor highly pathogenic viruses like Ebola or Marburg and yet they do not show clinical signs of disease. In a paper published in the journal Cell Host & Microbe on February 22, scientists at the Wuhan Institute of Virology in China find that in bats, an antiviral immune pathway called the STING-interferon pathway is dampened, and bats can maintain just enough defense against illness without triggering a heightened immune reaction.
To detect detect intestinal schistosome infections, the World Health Organization recommends using the Kato-Katz technique, which analyzes slides of fecal matter. But the approach often misses people who are infected with only a low burden of parasites and, as a consequence, shed only a few eggs in fecal samples. Researchers have now analyzed the efficacy of other testing approaches in a setting with low parasite burden; their results appear in PLOS Neglected Tropical Diseases.
Pre-clinical animal research is typically based on single laboratory studies conducted under highly standardized conditions. But in a new PLOS Biology study publishing Feb. 22, researchers from the Universities of Bern and Edinburgh show that this near-universal practice may actually help to explain the poor reproducibility of pre-clinical animal research. Instead of standardized conditions, diversity may be better.
Iron deficiency in the first four weeks of a piglet's life - equivalent to roughly four months in a human infant - impairs the development of key brain structures, scientists report. The abnormalities remain even after weeks of iron supplementation begun later in life, the researchers found.
