Environmental Change and Ecological Interactions

One of the most intriguing ecological challenges we face is understanding how species are shaped by their environment while predicting how those species and their interactions may change as their environment changes. We have been using aphids and their interacting species to study how such biotic and abiotic factors interact. Biotic factors include aphid interactions with the plants the aphids feed on, the natural enemies that feed on the aphids, and the symbiotic bacteria within the aphids. Abiotic factors include temperature, plant quality, UV, and others.

As an example, here is an abstract of a collaborative project we are working on along these lines.

 
       
 

Ecology and Behavior of Insect Pests

Insect pests sre a constant concern to North Dakota agriculture. Our goal has been to use insights from "basic" ecological and behavioral studies to help us answer "applied" questions about insect pests and the problems they create. For example, the soybean aphid is the most costly insect pest in soybean, but they can be incredibly frustrating because of tremendous variation in when and where they are a problem. By studying the ecology of this insect, we can work to identify key factors that help predict aphid problems and help producers plan accordingly.
