Jan. 27 - 'Invasive: Envisioning the Ecological Transformation of the Boundary Waters'

This public reception for the photo exhibit "Invasive" features a talk by the artist and by Lee Frelich, director of the U of M Center for Forest Ecology. The exhibit by David Luke combines photographic imagery of northern Minnesota's boreal forest with the state's southern and central prairies. The images visualize imminent transformations to land and water due to climate change and invasive species. 6-8 p.m., Architecture and Landscape Architecture Library.

Crowther and Reich: Soil carbon loss could accelerate global warming

A study, led by College of Food, Agricultural and Natural Resources Sciences (CFANS) Department of Forest Resources Adjunct Professor T.W. Crowther found that warming will drive the loss of at least 55 trillion kilograms of carbon from the soil by mid-century, adding an additional 17 percent on top of the projected emissions due to human-related activities during that period. Published in the journal Nature, the research drew from 49 climate change experiments worldwide, including six in Minnesota. Read the full story and watch the related video.

IonE welcomes 2017 class of IonE Affiliates

IonE associates are early-career scholars with exceptional promise to become internationally recognized for their environmental and sustainability research and to effect transformative environmental outcomes. They are selected based on nominations from current IonE Fellows with support from the nominee’s department chair or dean.

Diana Karwan
Assistant Professor, Department of Forest Resources, CFANS

Karwan uses field observations, chemical tracers and models to analyze the movement of water and waterborne materials such as sediment and carbon through watersheds, particularly in response to land use change, extreme weather events and climate change. Karwan’s work “spans basic to applied research in order answer questions of societal importance,” says Michael Kilgore, interim forest resources department head in CFANS. “She both develops the chemical tracing techniques as well as applies them to address research questions and management concerns.”

Study shows forest biodiversity is green in more ways than one

Loss of biodiversity has long been recognized as detrimental for nature. Now a team of scholars from 90 institutions in 44 countries has shown that it also provides enormous economic benefits. The finding highlights the need for a worldwide reassessment of biodiversity values, forest management strategies, and conservation priorities. The study was led by researchers including the Department of Forest Resource's Peter Reich, who is also engaged in presenting scientific findings through the YouTube channel, MinuteEarth.

A study, published in journal "Global Change Biology," involved research by more than two-dozen scientists, including Lee Frelich, director of the University of Minnesota's Center for Forest Ecology, Department of Forest Resources and an expert on Northeastern Minnesota forests. Frelich says the non-native worms consume the duff - the decaying leaves on the forest floor - as they eat their way across the continent's forests. They were first introduced by European settlers and, in recent decades, have spread rapidly through their use as fishing bait.  The worms alter the physical and chemical properties of soils, changing the pH, nutrient and water cycles and disrupting symbiotic relationships between soil fungi and tree roots.
