  • Temperature and Pollination in Greenland

    August 8, 2014

    Christine Urbanowicz, Ph.D. Student, Ecology and Evolutionary Biology Christine Urbanowicz studies the pollinators and plant-pollinator interactions that are beneficial for flowing plants in Greenland's tundra ecosystem. She is interested in how variation in plant density and temperature influence the number of pollinators that visit flowers and the number of fruits a plant produces. She is also collecting data on parasites of bumblebees in Greenland.

    Jessica Trout-Haney, Ph.D. Student, Ecology and Evolutionary Biology Jess Trout-Haney studies how climate change affects high latitude aquatic ecosystems, specifically their physical, biochemical, and biological properties. She studies how differences in lake chemistry and morphometry of low-nutrient Arctic lakes affect the abundance of cyanobacteria and cyanotoxins in southwestern Greenland.

    Earth Sciences Kristin is studying specific environmental controls, such as warming temperatures that are driving an increase in ice mass loss through Greenland's tidewater glaciers. She uses remote sensing (satellite imagery and time lapse cameras taking pictures of the glacier terminus) to determine how much of the glacier is experiencing melt and when meltwater exits the glacier and enters the fjord. The timing between melt onset and when the meltwater emerges gives her an idea as to how the meltwater travels through and below the glacier.

    Engineering Sciences Chris studies the Greenland Ice Sheet (GIS), which is the second largest ice cap in the world and contains 10% of Earth's glacial ice. In the past several years, melt on the GIS has been increasing and contributing to sea level rise, but understanding how rapidly the ice sheet will melt in the future remains fairly limited.

    Ecology and Evolutionary Biology Arctic soils contain more than half of the soil carbon that is stored worldwide. Because microorganisms are more active at higher temperatures, warming temperatures in the Arctic could cause a significant release of carbon from soils to the atmosphere, creating a positive feedback to climate change. Chelsea is measuring the sensitivity of Greenlandic soils to warming temperatures and determining if and how vegetative cover (shrub versus grass-dominated) influences belowground soil carbon dynamics.
