A wave of reptile extinctions on the Greek islands over the past 15,000 years may offer a preview of the way plants and animals will respond as the world rapidly warms due to human-caused climate change, according to a University of Michigan ecologist and his colleagues. The Greek island extinctions also highlight the critical importance of preserving habitat corridors that will enable plants and animals to migrate in response to climate change, thereby maximizing their chances of survival.
Michigan Sea Grant has been awarded more than $1.5 million from the federal government to lead two Great Lakes restoration projects that will restore native fish habitat and help clean up marinas across the region. It will also assist on five federally funded projects focused on issues including endangered fish, beach contamination, sound boating practices and marina operations, and water pollution.
Bradley J. Cardinale, who joins SNRE's faculty in January, has received a $2-million National Science Foundation grant as part of the agency's efforts to expand knowledge and understanding of Earth's biodiversity. Assistant Professor Cardinale is the principal investigator on a project titled, "Can evolutionary history predict how changes in biodiversity impact the productivity of ecosystems?" He and his colleagues will examine how evolutionary processes among algae generate and maintain the diversity of genes, and whether genetic diversity can explain the productivity of freshwater lakes.
Metamorphosis is stressful. So said SNRE professor of ecology and evolutionary biology Bobbi Low to incoming University of Michigan Rackham Graduate School students in the keynote lecture of the fall welcome ceremony on September 2. Professor Low, who used to research toad skin secretions, likened new doctoral students to tadpoles, which have no reproductive organs; by the time the students graduate, they will be metaphorical toads, producing new research and generating ideas.
SNRE Dean Rosina M. Bierbaum and Professors Andy Hoffman, Maria Carmen Lemos and Ted Parsons contributed to a series of recently published national reports on climate change. The National Research Council of the National Academies of Science produced the series, called America's Climate Choices, at the request of Congress.
Bridget Hohner, an SNRE Aquatic Sciences master's student, explains her research on the effects of chemicals to control sea lampreys on mussel populations in Michigan streams. The work is highlighted in a video produced by SNRE Professor Sara Adlerstein through special funding provided by the Rackham Graduate School.
University of Michigan aquatic ecologist Donald Scavia and his colleagues say this year's Gulf of Mexico "dead zone" is expected to be larger than average, continuing a decades-long trend that threatens the health of a $659 million fishery. The 2010 forecast, released today by the U.S. National Oceanic and Atmospheric Administration (NOAA), calls for a Gulf dead zone of between 6,500 and 7,800 square miles, an area roughly the size of Lake Ontario.
Two School of Natural Resources and Environment professors were among 10 University of Michigan faculty elected as Fellows of the American Association for the Advancement of Science. Dan Brown and Ivette Perfecto joined 530 scientists and researchers elected as part of an annual process conducted ty the AAAS. Professor Brown, who joined SNRE in 1999, was recognized for contributions to the understanding of the consequences of land-use change on ecosystems and human vulnerability via the innovative blending of social and ecological analysis. Professor Perfecto, who joined SNRE in 1989, was recognized for contributions to preserving biological diversity, particularly in demonstrating the importance of incorporating agricultural systems in models for conservation of biodiversity.
A University of Michigan-led research team is creating a comprehensive analysis and mapping of threats to the Great Lakes that will guide decision-making in the United States and Canada for years to come. The mapping and analysis project will produce the first-of-its-kind regional synthesis of human impacts on the Great Lakes, thereby helping regional planners and conservation groups to prioritize their activities. The Erb Family Foundation is funding the $500,000, two-year project. The project focuses on mapping threats to the lakes themselves, and will complement ongoing efforts focused on watersheds.
For the second consecutive year, The Journal of Great Lakes Research has given its annual award for best peer-reviewed paper to a researcher affiliated with the University of Michigan School of Natural Resources and Environment. Thomas Johengen received the 2009 Chandler-Misener Award for a paper titled, "Stimulation of Lake Michigan plankton metabolism by sediment resuspension and river runoff." He co-authored the paper with fellow researchers Bopaiah A. Biddanda and James B Cotner.
