This month, Dean Elde talks about the budget picture for the college in the coming biennium.
For more details about budget cuts and University policies, watch an audio slideshow (PPT) that explains some of the strategies that the U is adopting to reduce costs. The presentation was made to faculty and staff at meetings on the Minneapolis and St. Paul campuses earlier this month.
Tilman wins prestigious science prize
Regents’ Professor David Tilman (EEB) received the 2010 Heineken Prize for Environmental Sciences from the Royal Netherlands Academy of Arts and Sciences earlier this month. Tilman was selected for his seminal findings, published in Science and Nature during the 1980s and 1990s, which showed that biodiversity is essential for stable and productive ecosystems.
Tilman’s grassland experiments at Cedar Creek Ecosystem Science Reserve are among the longest running in the world, providing a rich resource for ecology research. His work at the field station is the subject of an article and a collection of short video clips recently published online by the University of Minnesota Foundation.
Two CBS faculty awarded Institute on the Environment fellowships

Study looks at “pressure cooker” approach to converting algae to coal
ScienceDirect | 2.10]
A recently published study led by Steve Heilmann, a research associate with the BioTechnology Institute (BTI), explores the potential for producing coal from algae using hydrothermal carbonization, a process that involves “pressure-cooking” algae. The process creates a substance similar to coal that can be converted into gasoline and other chemicals or burned to generate heat and electricity. Other BTI researchers involved in the study include Ken Valentas, Ted Davis, Lindsey Jader, Paul Lefebvre, Michael Sadowsky, Fred Schendel and Marc von Keitz.
Two studies shed light on plant fitness and reproduction
[Evolution | 3.10.10 + Ecology | 3.10]
Stuart Wagenius, a conservation scientist at the Chicago Botanic Garden and a former EEB graduate student, was lead author of two studies published online in March. In one study, Wagenius and a team of EEB researchers that included Ruth Shaw (EEB) artificially pollinated purple coneflower plants with pollen from distant, nearby, and related plants to gauge the effects of habitat fragmentation on plant fitness. The resulting plants were grown and measured for eight years. The researchers found that inbred plants (those with related parents) died more and flowered less than other plants—overall fitness was 68 percent lower.
In another study, Wagenius and fellow researchers looked at reproduction in the purple coneflower. For two years researchers observed native bee pollinators visiting plants in small and large prairie remnants in western Minnesota. They found that isolated plants had lower reproductive rates. In both years of the study, bees visited isolated individual plants the most and visitation rates did not vary with remnant size.
How immune cells move towards a chemical signal
[Proceedings of the National Academy of Sciences | 4.13.10]
Meg Titus (BMBB) and colleagues used a simple model system, the social amoeba Dictyostelium discoideum, to understand how immune cells such as leukcocytes and neutrophils respond to signals alerting them to clean up cellular debris from injury or infection. The process is important because it can trigger a cascade of events resulting in plaques on blood vessel walls. It’s also related to the way cancer cells metastasize.
Study will examine sources of variation within species
Tapping into a growing interest in understanding how epigenetic variation might contribute to phenotypic variation, Nathan Springer (PBIO) is leading a study that will look at the prevalence, heritability and potential consequences of epigenetic variation in maize. The National Science Foundation is providing more than $500,000 in support of the effort.
The research project will compare the DNA methylation patterns in the genome of nearly 30 different inbred lines (or breeds) of maize. DNA methylation can act as a “tag” to add additional information to DNA sequences and is one of several epigenetic marks. Epigenetics studies heritable variation that is not caused by DNA sequence changes. By adding information about the epigenome to a wealth of existing data on genetic and phenotypic information it will be possible to understand how epigenetic variation contributes to phenotypic variation within a species. The project will also study how epigenetic differences are inherited in hybrids and in recombinant inbred lines in order to assess the stability of epigenetic variation over multiple generations. The primary goal of this project is to document the role of epigenetic variation in heritable phenotypic variation within a species.
Undergraduate students from the University of Minnesota and Hamline University will participate in the primary research. All data produced by this project will be made public and available to researchers studying breeding and evolution across a wide range of disciplines.
