TL;DR
A patch dynamics model is constructed which can be used to simulate the changing sizes of resident populations in a series of interconnected habitat patches and predicts that mouse populations in isolated woodlots have lower growth rates and are thus more prone to extinction than those in connected woodlOTS.
Abstract
We constructed a patch dynamics model which can be used to simulate the changing sizes of resident populations in a series of interconnected habitat patches. We applied the model to white—footed mice (Peromyscus Leucopus) inhabiting patches of forest in an agricultural landscape. The model predicts that mouse populations in isolated woodlots have lower growth rates and are thus more prone to extinction than those in connected woodlots. Field data support this prediction.

In this Address, the author will attempt some quantification, but will not be able to emulate those former Presidents who have been able to provide a definitative synthesis of a field or of their own studies, and his offering can be but a small beginning, an indication of the type of characteristics the authors should quantify.

1,135 Citations1974Simon A. Levin
The spatial component of environment, often neglected in modeling of ecological interactions, in general operates to increase species diversity due to the heterogeneity of the environment, but such heterogeneity can arise in an initially homogeneous environment due to what may be random initial events (e.g., colonization patterns).

The effects of roadways on the movements of small and mediumsized mammals (small mammals less -than 700 g; medium-sized mammals 700 to approx. 14 000 g) are obtained from capture-recapture studies and from direct observation of roadway.

The results indicate that fencerows connect the wood to the surrounding agricultural mosaic and concentrate the activity of small mammals and birds into a habitat corridor that may relieve the isolating effect of farmland surrounding the wood.

It is shown that individual selection for or against dispersers may result in a stable polymorphism which depresses population numbers and prevents population fitness from being maximized.

It is shown that dispersal may increase the persistence time of a population by several orders of magnitude.

Results of simulation studies with population models that were set up to illustrate the ideas about stabilization of population fluctuations and spreading of the risk of extinction expounded by den Boer (1968) turn out that increasing the number of age classes may increase stability and that models where there is exchange of individuals between subpopulations by \ldmigration\rd are more stable than populations consisting of isolatedSubpopulations.

Summer densities were limited by decreased survival and increased dispersal of young, and these were most closely correlated with densities of adult females, therefore it is suggested that summer densities was regulated by aggressive female behavior.

Concurrent measures of habitat structure, plant species composition, and mouse density were performed at Point Pelee National Park, southern Ontario to establish plausible explanations of the factors determining patterns of local distribution and abundance of white-footed mice, Peromyscus leucopus.

The evidence suggests that Peromyscus are arranged in "family" groups consisting of one adult female, several adult males (one dominant, several subordinate, and a number of juveniles, and the results can better be explained by invoking behavior-mediated differences in trappability between species and/or ecological differences in the use of the habitat.

Analysis of arboreal components of two habitats of white- footed mice (Peromyscus leucopus) revealed that use of the components (branch height, angle and diameter) was proportional to their occur- rence.

Peromyscus maniculatus was most abundant early in succession when surface ground coverage was sparse and included little or no woody vegetation, but as cover of shrubs and trees increased, P. leucopus noveboracensis became more numerous, and P. manicULatus appeared from the community.

Colonies of mice, Peromyscus leucopus, often began to breed soon after being introduced to previously uninhabited islands in midsummer, although natural populations were not breeding at this season, which may have been caused by the disruption of social structure produced by the colonization.

The feeding diversity of immigrant Peromyscus leucopus is significantly greater than that of resident mice, consistent with the prediction that unpredictable environments are more likely to be populated by generalist feeders.
