A team of researchers led by wildlife ecologist Theresa Walter analyzed over 1,100 fox sightings made by the public as part of the citizen science project StadtWildTiere (www.stadtwildtiere.at). The joint team of researchers from the Vetmeduni Vienna and the University of Natural Resources and Life Sciences, Vienna (BOKU) now showed that foxes prefer specific city areas and environments. The study also revealed that reports of fox sightings correlated with the educational level of the population.
Team praises widespread commitment but calls for broader participation to better protect global marine ecosystems.
Four growing seasons after the engineered spring flood of the Colorado River Delta in March 2014, the delta's birds, plants and groundwater continue to benefit. The diversity and abundance of birds of special conservation concern remains high in the restoration sites, groundwater was recharged and some of the trees are now more than 14 feet (4.2 meters) tall, according to an International Boundary and Water Commission report prepared by a University of Arizona-led team.
Medical University of Vienna professor Leopold Eckhart and colleagues have performed one of the largest comparative genomic studies to help determine the key molecular and evolutionary origins of mammalian adaptations seen in skin proteins. "The results of the present study provide important new data on the evolution of keratins that control the mechanical stability of the epidermis, the outermost layer of the skin," said Eckhart.
Soot from road traffic in emerging countries can reach high altitudes, where it can be transported over long distances and thus contributes to global warming. The reduction of pollutants from road traffic such as soot particles from diesel cars should therefore have high priority in order to both protect the health of the population in the growing conurbations of emerging countries and reduce global warming, wrote a an international research team in Atmospheric Environment.
A new NASA-led study has determined that an increase in snowfall accumulation over Antarctica during the 20th century mitigated sea level rise by 0.4 inches. However, Antarctica's additional ice mass gained from snowfall makes up for just about a third of its current ice loss.
Researchers have combined artificial neural networks with infrared thermal imaging to control and interpret chemical reactions with new precision and speed. Novel microreactors allow chemical discoveries to take place quickly and with far less environmental waste than standard large-scale reactions. The system can reduce the decision-making process about certain chemical manufacturing processes from one year to a matter of weeks, saving tons of chemical waste and energy in the process.
As expected, tropical cyclone Owen recently intensified as it moved over the Gulf of Carpentaria and NASA and the Japan Aerospace Exploration Agency's GPM core satellite found very heavy rainfall occurring within the revived storm. The storm has made a U-turn in the Gulf and is now headed back to Queensland.
Many species of mammals have evolved what appear to be paradoxical behaviors towards their young. Like humans, most exhibit nurturing, protective behaviors, and in some circumstances even act as surrogate parents. However, virgin males often engage in infanticide as a strategy to propagate their own genes. How are these conflicting social behaviors controlled?
Our understanding of when the very first animals started living on land is helped by identifying trace fossils--the tracks and trails left by ancient animals--in sedimentary rocks that were deposited on the continents.
