Friday seminar: Disturbance, diversity and invasion ecology

By Prof. Katriona Shea, Penn State, US.


Disturbances are ubiquitous in nature, and may contribute to biological invasions.  The need to address the impacts of environmental perturbations is increasingly urgent in the face of anthropogenic alterations to existing disturbance regimes. In her talk, Shea will discuss how a framework involving six interacting aspects of disturbance regimes (frequency, intensity, duration, extent, timing and pace) can be used to study a wide range of issues related to basic and applied outbreak ecology. This framework can be used to improve empirical design and biological interpretation, which in turn leads to more efficient management. Ongoing research not only informs us about when disturbances are likely to exacerbate invasions, but also lets us assess how we can manipulate disturbances to achieve desired management outcomes.


Currently a guest researcher at CEES, Katriona Shea is an alumni professor of biology at the Department of Biology at Eberly College of Science, Penn State, US.

She is also a faculty member of the Intercollege Graduate Degree Program in Ecology at the Huck Institutes of the Life Sciences. Her primary research interest is in the use of ecological theory in population management, addressing issues in invasion ecology, epidemiology, conservation and harvesting.
