Predation and competition are perhaps the two most important processes in structuring wildlife communities. Early studies of these processes focused on estimating how these interactions between animals affected their population dynamics.
With regard to predation, there is ample evidence from past research to suggest predators can suppress populations of the species they prey upon. For the competition, it is generally accepted that competition within a species is a far more important factor than competition between species in terms of population dynamics.
Our current research studying the effects of predation and competition can be broken into two general areas, direct versus indirect influences.
Our work with direct influences includes topics such as:
- The conditions under which prey species are likely to be suppressed by predators
- Impacts of novel, or non-native, species on population dynamics of native wildlife
- Competition between predators and obligate scavengers, including insects, with regard to carrion detection and consumption
We also study the indirect effects of interactions between animals. While the indirect effects of competition have been studied for decades, the indirect effects of predation have been less explored until recently. Much of that work, including that conducted at the Jones Center, suggests that the indirect effects of predation may have greater impacts on prey population dynamics than the direct killing of prey by predators.
Much of our current research involves the study of indirect effect of predators on their prey and includes topics such as:
- How different types of predators influence prey foraging behavior
- How predator species composition and abundance affects prey habitat selection and activity patterns

These tangible benefits, often termed ecosystem services,
give forests measurable value to people aside from the economic value of the timber.
This research theme centers on understanding and quantifying these values as they relate to longleaf pine woodlands, and identifying vulnerabilities of these ecosystems to climate variations, disturbances, and changes in management.


This theme builds on several interconnected long-term data sets at the Center, including measurements of
Numerous other studies have examined diverse topics ranging from tree defenses against bark beetle attack to the effects of nitrogen fertilization on plant diversity. Studies in this theme currently focus on the effects of fire suppression on forest resilience and ecosystem services, and the effects of Hurricane Michael on ecosystem function.
