UA researchers have discovered some of the changes in genes, physiology and behavior that enable a species to drastically change its lifestyle in the course of evolution.
Daniel Chitwood, Ph.D., assistant member, and his research group at the Donald Danforth Plant Science Center's in St. Louis, in collaboration with the laboratory of Neelima Sinha, Ph.D., at the University of California, Davis, are using the world's largest single-celled organism, an aquatic alga called Caulerpa taxifolia, to study the nature of structure and form in plants. They have recently reported the results of their work in the online journal, PLOS Genetics.
A team of California scientists believes a far-flung Okenia rosacea bloom -- along with a slew of other marine species spotted north of their typical ranges -- may signal a much larger shift in ocean climate and a strong forthcoming El Niño.
After decades of field work from dozens of sites around the world, and after two years of combing through and analyzing data, Matt Forister from the University of Nevada, Reno, and an international team have reported on global patterns in the diets of insect herbivores. They report that most insect herbivores, such as caterpillars, find and feast on just one kind of plant in any one location, rather than eating everything in sight.
The Great Lakes are the freshwater system that has been the most invaded by non-native species. Researchers predict they will remain vulnerable to future waves of invasions, unless some US-Canadian coordinated measures are implemented. The scientists also identify some species at high risk of being in the Lakes by 2063, if nothing is done.
University of Leicester team find for the first time when and why dopamine releasing cells in the forebrain are activated.
New research by the University of Sheffield has warned of the increasing risk of extinction to our marine life.
The western Amazon -- a vast region encompassing the Amazonian portions of Bolivia, Colombia, Ecuador, Peru, and western Brazil -- is one of the world's last high-biodiversity wilderness landscapes. It is also home to an active hydrocarbon (oil and gas) sector, characterized by operations in extremely remote areas that require new access routes.
A new acoustic fish-tracking tag is so tiny it can be injected with a syringe. It's small size enables researchers to more precisely and safely record how fish swim through dams and use that information to make dams more fish-friendly.
The efficient production of both biofuel and animal feed from one crop is now possible, and can be done on a farm without the need for off-site processes. The research, published in the open access journal Biotechnology for Biofuels, demonstrates the practical potential of an alternative to fossil fuels that does not compete with food resources.
