My research interests within community ecology include species interactions, top-down and bottom-up effects and the effect of allochthonous subsidies on communities. I’m also interested in the connections between adjacent ecosystems, e.g., aquatic and terrestrial systems. My dissertation focused on factors that influence the relative importance of top-down and bottom-up effects, using the model food webs found within the leaves of pitcher plants. Currently I’m studying the effects of midges as a resource subsidy to the land surrounding lakes where midges spend their larval stage before emerging as adults.
A view of the Myvatn region of northern Iceland, looking down at a lava field and a beautiful eutrophic lake in the background. Every year midges emerge from the water en masse and provide a major subsidy to surrounding terrestrial food webs. |

Collecting midges along the shores of Myvatn. These midges were used in fertilization experiments in areas that do not receive the influx of nutrients that this lush hillside receives in the form of millions of midge carcasses. |
