Species Diversity In Coral Reefs Hints At How Coral Responds To Climate Change

RedOrbit: It is widely known that coral reefs are being put in jeopardy by rising water temperatures caused by climate change. A team of marine biologists, led by Penn State University, has made a surprising discovery that suggests that very similar looking coral species actually differ in how they survive in harsh environments. "We`ve found that previously unrecognized species diversity was hiding some corals` ability to respond to climate change," said Iliana Baums, associate professor of biology at Penn...

Arctic at risk from invasive species

Ecologist: As oceans continue to warm, the number of ships bearing invasive species will increase, and the number of species that may be able to survive in Svalbard will increase. More shipping is sailing through thawing Arctic waters, but while these northern routes might provide opportunities for tourism, mining and cutting down delivery times, the ships may also carry stowaways on board, introducing invasive species to pristine Arctic waters. These findings were recently published in the journal Diversity...

Biodiversity higher in the tropics, but species more likely to arise at higher latitudes

ScienceDaily: A new study of 2300 species of mammals and nearly 6700 species of birds from across the globe helps explain why there are so many more species of plants and animals in the tropics than at higher latitudes. In a study supported by the National Evolutionary Synthesis Center in North Carolina, researchers found that while the tropics harbor a greater diversity of species, the number of subspecies -- potential stepping stones in the process by which one species becomes two -- is actually greater in the...
Researchers study how preserve tree species amid climate change

Tuscon Sentinel: Two researchers at Arizona State University are aiming to help officials manage trees based on how different types are affected by climate change. Janet Franklin, a geography professor, and Pep Serra-Diaz, a postdoctoral researcher, are using computer models to study how quickly a tree species and its habitat will be exposed to climate change. That information is used to locate areas with specific elevations and latitudes where trees could survive and repopulate. "This is information that would...

Trees 'shield vulnerable species from climate change'
2013-11-02 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
BBC: Forests with dense canopies create a microclimate that protects a variety of cold-adapted plant species from warming air temperatures, a study has shown. Researchers found plants that favoured cooler conditions fared better under dense canopies than in ones that were more open to the elements. They added that these conditions could be a "critical mechanism" in the conservation of forest plant diversity. The findings appear in the Proceedings of the National Academy of Sciences. A team...
