As the Arctic continues to change due to rising temperatures, melting sea ice and human interest in developing oil and shipping routes, it's important to understand belugas' baseline behavior, argue the authors of a new paper.
On Charles Darwin's 207th birthday, a new study of evolution in a diverse group of wild tomatoes is shedding light on the importance of genetic variation in plants.
Like the lionfish in the Caribbean, a large fish called Cobia, which has escaped from an aquaculture facility in Ecuador, has the potential to become an important invasive species in the Central and Eastern Pacific
Whether an animal or plant community remains stable does not depend on diversity alone: asynchrony across the species is also a crucial factor. The more asynchronous the species in an ecosystem fluctuate in their abundances, the less likely it becomes unstable. As a result, diversity takes second place in terms of the factors to be considered in the context of ecosystem stability. Scientists spearheaded by the TU Munich and TU Darmstadt have published these findings in the journal Nature Communications.
A study reported today in the journal PLOS Biology employs genome-wide sequencing to the reveal highly specific details about the evolutionary mechanisms that drove genetic divergence in 13 species of wild tomatoes that share a recent common ancestor. The in-depth genetic analysis was led by Leonie C. Moyle, professor in the IU Bloomington College of Arts and Sciences' Department of Biology.
A panel of British and American researchers, speaking at the annual meeting of the American Association for the Advancement of Science in Washington, D.C., will present updated research revealing how extreme events which affect the food system are increasingly likely to occur, resulting in 'food shocks.'
Paul West, co-director and lead of the Institute on the Environment's Global Landscapes Initiative, will present at the annual meeting of the American Association for the Advancement of Science on Feb. 12. West will discuss opportunities for subsistence farmers to enhance productivity while considering climate change, water availability and quality, and habitat loss.
A recent study provides new evidence that larvae swim faster, straighter and more consistently in a common direction when together in a group. The research led by scientists at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science is the first to observe group orientation behaviors of larval fish.
A natural extract derived from India's neem tree could potentially be used to treat pancreatic cancer, according to a new study in the journal Scientific Reports.
A study has concluded that significant outbreaks of viruses may be associated with coral bleaching events, especially as a result of multiple environmental stresses. One such event was documented even as it happened in a three-day period. It showed how an explosion of three viral groups, including a herpes-like virus, occurred just as corals were bleaching in one part of the Great Barrier Reef off the east coast of Australia.
