TLDR
Metapopulation studies have important conceptual links with the equilibrium theory of island biogeography and with studies on the dynamics of species living in patchy environments as mentioned in this paper, and they play an increasingly important role in landscape ecology and conservation biology.Abstract:
We review the early development of metapopulation ideas, which culminated in the well-known model by Levins in 1969. We present a survey of metapopulation terminology and outline the kinds of studies that have been conducted on single-species and multispecies metapopulations. Metapopulation studies have important conceptual links with the equilibrium theory of island biogeography and with studies on the dynamics of species living in patchy environments. Metapopulation ideas play an increasingly important role in landscape ecology and conservation biology.read more

Effects of habitat fragmentation on birds and mammals in landscapes with different proportions of suitable habitat: a review
TL;DR: Simulations of patterns and geometry of landscapes with decreasing proportion of the suitable habitat give rise to the prediction that the effect of habitat fragmentation on e.g. population size of a species would be primarily through habitat loss in landscape with a high proportion of suitable habitat.

Competition and Biodiversity in Spatially Structured Habitats
TL;DR: The spatial competition hypothesis seems to explain the coexistence of the numerous plant species that compete for a single limiting resource in the grasslands of Cedar Creek Natural History Area and provides a testable, alternative explanation for other high diversity communities, such as tropical forests.

Directions in conservation biology
TL;DR: The small-population paradigm has not yet contributed significantly to conserving endangered species in the wild because it treats an erect (smallness) as if it were a cause and hence is of scant theoretical interest.

Landscape modification and habitat fragmentation: a synthesis
TL;DR: In this article, the authors focus on individual species and the processes threatening them, and human-perceived landscape patterns and their correlation with species and assemblages, as well as additional, stochastic threats such as habitat loss, habitat degradation, habitat isolation and habitat isolation.
Dissertation
Formalising Trust as a Computational Concept
TL;DR: The thesis presents a testbed populated by simple trusting agents which substantiates the utility of the formalism and provides a step in the direction of a proper understanding and definition of human trust.

The Genetical Evolution of Social Behaviour. I
TL;DR: A genetical mathematical model is described which allows for interactions between relatives on one another's fitness and a quantity is found which incorporates the maximizing property of Darwinian fitness, named “inclusive fitness”.

The Evolution of Reciprocal Altruism
TL;DR: In this paper, a model is presented to account for the natural selection of what is termed reciprocally altruistic behavior, and the model shows how selection can operate against the cheater (non-reciprocator) in the system.

Sources, Sinks, and Population Regulation
TL;DR: If the surplus population of the source is large and the per capita deficit in the sink is small, only a small fraction of the total population will occur in areas where local reproduction is sufficient to compensate for local mortality, and the realized niche may be larger than the fundamental niche.
