The mountain pine beetle [MPB, Dendroctonus ponderosae Hopkins (Coleoptera: Scolytidae)] is an aggressive bark beetle, one that typically needs to kill host trees in order to successfully reproduce. This ecological adaptation has resulted i...
Evolutionary Stable Strategies and Trade-Offs in Generalized Beverton and Holt Growth Models [0.03%]
广义Beverton和Holt增长模型下的进化稳定策略及折衷方案研究

A generalized Beverton-Holt model is considered in which a parameter gamma characterizes the onset of density dependence. An evolutionary stable strategy analysis of this parameter, reported in Getz (1996), is developed further here, using ...

Chaotic dynamics have been observed in a wide range of population models. Here we describe the effects of perturbing several of these models so as to introduce a non-zero minimum population size. This perturbation generally reduces the like...
Habitat Deterioration, Habitat Destruction, and Metapopulation Persistence in a Heterogenous Landscape [0.03%]

Levins's unstructured metapopulation model predicts that the equilibrium fraction of empty habitat patches is a constant function of the fraction h of suitable patches in the landscape and that this constant equals the threshold value for m...
Using Moment Equations to Understand Stochastically Driven Spatial Pattern Formation in Ecological Systems [0.03%]
利用时刻方程理解随机驱动生态系统的空间模式形成

Spatial patterns in biological populations and the effect of spatial patterns on ecological interactions are central topics in mathematical ecology. Various approaches to modeling have been developed to enable us to understand spatial patte...

We introduce a simple mathematical model to describe the behavior of a forager with a limited memory capacity in the presence of two prey types that differ in their energetic values. The model is used to analyze the effect of memory capacit...
Revisiting Strategic Models of Evolution: The Concept of Neighborhood Invader Strategies [0.03%]

In game-theoretic or strategic models of species evolution, the phenotype of individual organisms in a population are regarded as alternate strategies for playing a competitive game. The evolutionary outcome is predicted to conform to the "...

Trees that describe the ancestry of DNA sequences sampled from a population may differ between loci because of genetic recombination. We seek to understand the relationship between such trees for loci that are linked with non-zero recombina...
Density-Dependent Patch Exploitation and Acquisition of Environmental Information [0.03%]
基于密度的生境斑块利用与环境信息的获取机制研究

MA Rodríguez-Gironés
We study density-dependent resource harvest patterns due to Bayesian foraging for different distributions of resources. We first consider a forager with information about the stochastic properties of its environment. In this case we show th...
Coupling and the Non-degeneracy of the Limit in Some Plasmid Reproduction Models [0.03%]

We settle a problem raised by Seneta and Tavare concerning the normalized limits of several plasmid reproduction models. We also show that for countably infinitely many type branching processes the extinction probability and the mass at the...
