Research suggests climate change affecting plants above ground more than below
It's a long way between central Pennsylvania and Greenland — at least 2,000 miles — but Laura Radville came to Penn State so she could study climate change in the "Iceberg capital of the world." However, the research conducted in Greenland by the Boston native did not deal with ice at all, but rather plants — arctic shrubs to be specific. Her work focused on how rising air temperatures are affecting the growth of leaves and stems much more than the growth of roots, perhaps "uncoupling" aboveground and belowground plant development, or phenology.

Scientists at Penn State study endangered coral species' relationship with algae
New research reveals that Caribbean corals and the algae that inhabit them form a remarkably stable relationship -- new knowledge that can serve as an important tool in preserving and restoring vital reef-building corals. Coral reefs are important for protecting shorelines, providing seafood, and generating millions of dollars in recreation revenue each year, but rising water temperatures due to climate change are stressing many corals to the point of extinction. The Penn State researchers -- Iliana Baums and Todd LaJeunesse, both associate professors of biology, and research technologist Meghann Durante -- conducted a large-scale genetic study of Caribbean elkhorn coral, Acropora palmata. Once the primary reef-building coral species throughout the Caribbean, A. palmata now is listed as endangered under the U.S. Endangered Species Act. The biologists worked on the sub-species level using high-resolution genetic markers that allowed them to examine individual coral colonies and their symbiotic partnerships with single-celled algae.
