Researchers receive $1.14 million to study threats to honey bees
Date:4/4/2014

scholar in biology, Katriona Shea, professor of biology, and Reka Albert, professor of physics and of biology, will model perturbations to ecosystem structure, specifically the permanent or temporary removal or introduction of one or more species.

"This model will allow us to assess which species and ecosystem properties contribute to the susceptibility of an ecosystem to catastrophic failure, and which contribute most to stability," said Campbell.

According to Shea, the need to address the impacts of environmental perturbations is increasingly urgent.

"The addition or loss of species to existing ecological communities can have far-reaching consequences for both the community and the greater ecosystem in which the community is embedded," she said. "For example, the recent, rapid decline in pollinator levels poses a serious risk to global agriculture and food security. This project will advance our knowledge of how these complex systems function. Only if we can anticipate the effects of environmental perturbations can we act to prevent or ameliorate undesired outcomes."
