On the Dynamic Dichotomy between Positive Equilibria and Synchronous 2-cycles in Matrix Population Models
For matrix population models with nonnegative, irreducible and primitive inherent projection matrices, the stability of the branch of positive equilibria that bifurcates from the extinction equilibrium as the dominant eigenvalue of the inherent projection matrix increases through one is determined …

Dynamic energy budgets and bioaccumulation : a model for marine mammals and marine mammal populations
… affects growth of organisms and, therefore, populations. Persistent lipophilic toxicants acquired with the energy can bioaccumulate and harm individuals. Marine mammals are particularly vulnerable because of their large energy requirements, and transfer of energy and toxicants from mothers to …

Ornate box turtle (Terrapene ornata) demography in northern Illinois
Demographic studies of wildlife populations are needed to guide management decisions for threatened species. Without data on population vital rates, decisions are often speculative and based on general information about a species rather than at the population level. The Ornate Box Turtle (Terrapene …

Mark-recapture statistics and demographic analysis
Mark-recapture analysis of populations is becoming an important tool in population biology. Mark-recapture methods can be used to estimate transition probabilities among life-stages from capture histories of marked individuals for which stages can be determined at each sampling occasion. This …

Transient dynamics in plant population models
… short-term responses to unstable conditions in population models. Although the theoretical potential of these short-term effects to change interpretation of model behavior has been demonstrated, it is unclear whether transient analyses will be relevant or useful in management applications. This …

Life history traits and population processes in marine bivalve molluscs
… of the clam Mya arenaria determine the population response to chronic contaminant exposure. To predict the potential responses of a broadcast-spawning life history such as that of M. arenaria, I surveyed the literature on a variety of bivalve species. By incorporating information on …

Developing and assessing methods to census and monitor burrow-nesting seabirds in Ireland
Censusing and monitoring populations are key priorities in conservation. This is particularly challenging for seabirds, where several life history characteristics and the remote nature of breeding colonies of many species make them difficult to study. Burrow-nesting species are the most difficult …
