Stocking Florida bass in Texas reservoirs may alter stream systems connected to stocked reservoirs
A genetic analysis by Baylor University biologists suggests that the stocking of Florida bass in Texas reservoirs impacts bass populations far beyond the actual stocking location.
Activists fight FDA approval of AquaBounty's genetically engineered salmon
Every summer since 1979, Kim Hubert has fished for sockeye salmon in Alaska's Bristol Bay. It's a family business in tiny Togiak that has, from time to time, also employed his wife and three children.
Dead seals serve conservation boost
Scientists have used genetic testing on animals that died of natural causes for the first time, potentially boosting efforts to save endangered species.
Biologists explore link between amphibian behavior and deadly disease
In a new study, biologists will investigate the connection between amphibians' social habits and a disease that has killed a record number of frogs, toads and salamanders worldwide.
Agriculture and parting from wolves shaped dog evolution, study finds
(Phys.org)—Part of the ancient mystery of the makeup of the modern Western dog has been solved by a team led by researchers at the University of California, Davis, School of Veterinary Medicine.
Study shows cultural flow may be slower than genetic divergence
Plant geneticists demonstrate new means of boosting maize yields
A team of plant geneticists at Cold Spring Harbor Laboratory (CSHL) has successfully demonstrated what it describes as a "simple hypothesis" for making significant increases in yields for the maize plant.
Ancient DNA reveals humans living 40,000 years ago in Beijing area related to present-day Asians, Native Americans
An international team of researchers including Svante Pääbo and Qiaomei Fu of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, sequenced nuclear and mitochondrial DNA that had ...
A global approach to monitoring biodiversity loss
In contrast to climate change, there is no coordinated global system in place for measuring and reporting on biodiversity change or loss. An international team of biologists is now addressing this gap.
Gene flow from India to Australia about 4,000 years ago
Long before Europeans settled in Australia humans had migrated from the Indian subcontinent to Australia and mixed with Australian aborigines.
Chlamydia threat to untouched koala population
(Phys.org)—An outbreak of koala chlamydia in the Southern Highlands also poses a threat to a completely unaffected colony in Campbelltown.
Optimal population size allows maximum predictability of evolution
(Phys.org)—Evolution in very large populations of plants, animals or fungi can be predicted far less easily than one would expect. This has been shown by research at the Institute for Theoretical Physics ...
Chemists devise inexpensive, benchtop method for marking and selecting cells
Chemists at The Scripps Research Institute (TSRI) have found an easier way to perform one of the most fundamental tasks in molecular biology. Their new method allows scientists to add a marker to certain cells, so that these ...
Genomic study discovers evidence of giant panda's population history and local adaptation
A research team, led by Institute of Zoology of Chinese Academy of Sciences and BGI, has successfully reconstructed a continuous population history of the giant panda from its origin to the present. The findings ...
