Protecting key regions that comprise just 17 percent of Earth’s land may help preserve more than two-thirds of its plant species, according to a new study by an international team of scientists, including a biologist from North Carolina State University.

The researchers from Duke University, NC State and Microsoft Research used computer algorithms to identify the smallest set of regions worldwide that could contain the largest numbers of plant species. They published their findings in the journal Science. (more…)

ANN ARBOR, Mich.— Twenty years after the Earth Summit in Rio de Janeiro, 17 prominent ecologists are calling for renewed international efforts to curb the loss of biological diversity, which is compromising nature’s ability to provide goods and services essential for human well-being. (more…)

Ecosystem Effects of Biodiversity Loss Could Rival Impacts of Climate Change, Pollution

ANN ARBOR, Mich.— Loss of biodiversity appears to impact ecosystems as much as climate change, pollution and other major forms of environmental stress, according to a new study from an international research team.

The study is the first comprehensive effort to directly compare the impacts of biological diversity loss to the anticipated effects of a host of other human-caused environmental changes.

The results highlight the need for stronger local, national and international efforts to protect biodiversity and the benefits it provides, according to the researchers, who are based at nine institutions in the United States, Canada and Sweden. (more…)

New Computer Programme Promises To Save The Whales

Researchers at the University of Montreal have developed a computer programme that enables regulators to evaluate the ecological and economic tradeoffs between marine mammal conservation, whale watching and marine transportation activities in the Saint Lawrence Estuary.

“The objective is to reduce the collision risk with whales while taking into account the impact on industry and marine transportation,” said Lael Parrott, who headed the research team. The model, developed in her Complex Systems Laboratory, maps the estuary where the field research was undertaken, simulates the comings and goings of five mammal species (minke whale, fin whale, beluga, humpback and blue whale), the presence and movements of three types of boats (recreation, excursion and cargo), and environmental conditions. Nine scenarios were elaborated in order to observe the effects of various decisions. (more…)

Border Fences Pose Threats to Wildlife on U.S.-Mexico Border, Study Shows

AUSTIN, Texas — Current and proposed border fences pose significant threats to wildlife populations, with those animals living in border regions along the Texas Gulf and California coasts showing some of the greatest vulnerability, a new study from The University of Texas at Austin shows.

“Our study is the first comprehensive analysis of threats to species across the entire U.S.-Mexico border,” says Jesse Lasky, a graduate student in the laboratory of Tim Keitt, associate professor of integrative biology. “The scale at which these fences stretch across the landscape is large, so it’s important for us to also have a large-scale view of their effects across the continent.” (more…)
