Research Interests

Most recently my research interests have centered on The Ecology of Information – defined as the study of how organisms acquire information to manage their daily lives of finding food, avoiding predators, selecting habitats, etc., and its significance for populations, communities, and ecosystems. A passage from Smith (1977:193) captures the essence of information in ecology as “… an abstract property of events and entities that makes their characteristics predictable to individuals…(It) enables …individuals to make choices, to select their activities…appropriately for their needs and opportunities”.

The Ecology of Information is an overarching theme of several current research projects, including:

Eavesdropping and predation risk - do heterospecifics (including birds and mammals) use avian alarm calls to adjust their perception of predation risk and are their important fitness consequences?

Settlement and nest-site decisions – how do prey (e.g., breeding songbirds) use information do locate high quality (e.g., low predator) sites? We are exploring this empirically by manipulating predator vocalizations to determine if birds use these as a proximate cue to avoid their nest predators in time and space. Theoretically, Dr. Rich Straus (TTU) and I have built a Matlab-based population simulation model to explore how prey settlement strategies influence prey density, growth rate, stability, and persistence.

Eavesdropping and cognitive abilities of caching in tree squirrels. This work investigates caching-pilfering systems, such as blue jays
and tree squirrels, as information networks.
