Boulder, Colo.--The Geological Society of America's December issue of GEOLOGY contains several potentially newsworthy items. Topics of particular interest include: new results from study of Lake Tanganyika sediment cores and impacts of deforestation on the lake's biodiversity; changes in Earth's biogeography and its relationship to changes in plate tectonics; new analysis of Martian gullies based on images supplied by the Mars Global Surveyor spacecraft; a Norian-Rhaetian extinction event that may have preceded the end-Triassic mass extinction; and new evidence regarding the Paleocene-Eocene thermal maximum (PETM) and the dramatic global warming that followed it 55 million years ago.

Highlights are provided below. Please discuss articles of interest with the authors before publishing stories on their work, and please make reference to GEOLOGY in stories published.

Please note that GSA will close for the Thanksgiving holiday at 12:00 p.m. MST on Wednesday, November 27. The office will reopen Monday, December 2.

Effects of land-use change on aquatic biodiversity: A view from the paleorecord at Lake Tanganyika, East Africa.
Simone R. Alin, Department of Geosciences, University of Arizona, Tucson, Arizona 85721, USA, et al. Pages 11431146.

Researchers at the University of Arizona and their colleagues used sediment cores from Lake Tanganyika in East Africa to study the effects of deforestation on biodiversity in the lake. Lake Tanganyika is home to over 2,000 species, making it the most biologically diverse tropical lake on the planet. The research, coordinated by Dr. Simone Alin, compared sediment cores collected offshore from Gombe Stream National Park in Tanzania, the site of Jane Goodall's chimpanzee research, with cores collected offsh
