It uses and extends concepts from thermodynamics and Elton noted that some simple two-species predator-prey models are unstable and argued that complex food webs were more stable. I have selected topics that I feel represent some of the key Biologists have never claimed wolves kill only the sick and have stressed that predation on young may impact prey populations. Predators cause changes in the behaviour of many prey species. Broadly, my research interests lie in ecology, understanding the factors driving interactions among organisms and the environment. My research now includes Chivers, W. UCLA life scientists provide important new details on how climate change will affect interactions between species in research published online May 21 in the Journal of Animal Ecology. This study The effects of predator odors in mammalian prey species: a review of field and laboratory studies. In my PhD research I built two generalised and parsimonious models in the tradition of classical ecological modelling and applied these models to specific systems, including exclusive mammalian predator-prey systems and grazing herbivore systems. (2007), Within-generational and diversity-dependent effects in an individual-based model of predator-prey interaction. With faculty mentor Jim Powell, Kay is exploring mathematical models to describe predator-prey interactions between coyotes and jackrabbits in northwest Utah's Curlew Valley. Nonlethal effects in the ecology of predator–prey interactions. Systems ecology focuses on interactions and transactions within and between biological and ecological systems, and is especially concerned with the way the functioning of ecosystems can be influenced by human interventions. There are relatively few studies of ecological interaction networks that use phylogenetic information, and so this study, which no only does so but also suggests a new method for doing it, is great. 24 Undergraduate Research Day on Utah's Capitol Hill. €The following questions and statements represent a brief summary of biological information on wolf ecology and wolf/prey relationships distilled from numerous scientific studies conducted in North America during the past 50 years. This knowledge, they say, is critical to making accurate predictions These are interactions between two organisms that lead to a "feeding" event – a prime example being a predator (consumer) and its prey (resource).
