    The world's forgotten greenhouse gas

    In the world's effort to cut greenhouse gas emissions, the source of our food is coming into the spotlight. There's good reason for that: Agriculture accounts for 16 to 27% of human-caused climate-warming emissions. But much of these emissions are not from carbon dioxide, that familiar climate change villain. They're from another gas altogether: nitrous oxide (N2O).

    Cao receives Brown Graduate Fellowship

    Peiyu Cao is one of the fourteen Iowa State University students to be selected to receive $140,000 in Brown Graduate Fellowship Program funding to support strategic university research over the next year. Peiyu’s research focuses on the assessment of the nitrogen budget within agricultural systems through data synthesis and empirical and process-based modeling. This work has served as a solid basis for crop yield estimation, environmental consequence analysis, and economic assessment, and will benefit a broad community far beyond ecosystem modelers.

    As climate change cranks up the heat in the Mojave Desert, not all species are equally affected

    AMES, Iowa – Climate change doesn’t affect every species equally.

    Even among species that share the same habitat, some organisms adapt more readily than others to environmental fluctuations wrought by climate change. This realization has led biologists to try to predict which species are most vulnerable to climate change.

  • Herbarium

    The Ada Hayden Herbarium has grown to ~660,000 specimens and is the 12th largest US university herbarium. Its holdings are diverse, especially for Iowa’s plants and fungi (including lichens), but also with significant holdings that reflect research from beyond the state’s borders. The University of Iowa Herbarium’s fungal holdings were transferred here in 1984, followed by the remainder of the U of I Herbarium in 2004. Lynn Clark has served as the Director and Deb Lewis as the Curator since the 1980s.

    Searching the ancient depths of a reptilian genome yields insight into all vertebrates

    AMES, Iowa – Scientists searching the most ancient corners of the genome of a reptile native to New Zealand found patterns that help explain how the genomes of all vertebrates took shape, according to a recently published study.

    The study, completed by a global team of collaborators and published in the journal Nature, details for the first time the assembled genome of the tuatara, a rare reptile species of great cultural significance to indigenous populations in New Zealand.

    A Viral Battle In The Honey Bee Hive

    New research published this week in the Proceedings of the National Academy of Sciences indicates that honey bees infected with a virus may alter their behavior in ways that slow the spread of the infection. At the same time, infection with the virus may help the bees sneak into neighboring hives, potentially spreading the virus to new hosts.

    Researchers Find Bee Virus Spreads by Altering Honey Bees’ Social Distancing Behavior

    AMES, Iowa — A new study conducted by researchers at Iowa State University and the University of Illinois suggests a deadly virus attacking honey bees alters their behavior and physiology in ways that boost the virus’ ability to spread.

    The research, reported in the current issue of the Proceedings of the National Academy of Sciencesfound the Israeli Acute Paralysis Virus, known as IAPV, seems to change bee behavior in ways that overcome some of bees’ natural defenses against disease pathogens.
