Incorporating territory compression into population models

Article Abstract:

Two different approaches are introduced to show that the effects of both territory shrinkage and territorial disputes on reproductive success that needs to be incorporated in the modeling the population dynamics of the species. Studies emphasize the need for factoring the impact of intrinsic regulation through territory shrinkage and territorial disputes on reproductive success.

Relatedness and competitive asymmetry-implications for growth and population dynamics

Article Abstract:

A model describing the growth and population dynamics of related and unrelated individuals under the different symmetric and asymmetric competition regimes is presented. Results of experiments using this model suggest that individual differences and asymmetry of competition can greatly affect population dynamics.

Density estimation in live-trapping studies

Article Abstract:

A new and general method for estimating density from closed-population capture-recapture data is described. The method uses any configuration of traps (e.g.grid, web or line) and any choice of closed-population estimator.
