The community context of species' borders: Ecological and evolutionary perspectives
Article Abstract:
A number of models of interspecific interactions that lead to distribution limits in the presence and absence of environmental gradients is explored. It is concluded that gradients in competitive ability can lead to spatial segregation of competitors into distinct ranges, but that spatial movement tends to broaden the region of sympatry between the two species, and that Allee effects tend to sharpen these boundaries.

Impacts of temporal variation on apparent competition and coexistence in open ecosystems
Article Abstract:
The impact of external subsidies on apparent competition between a pair of species sharing a natural enemy is examined. The examples of the rich range of outcomes that may arise due to temporal variability in spatially heterogeneous landscapes is presented with the help of theoretical studies.

Species' borders: A unifying theme in ecology
Article Abstract:
The ecological and evolutionary dynamics of species' borders from diverse empirical and theoretical perspectives is explored. Species' demographic responses along gradients of increasing environmental stress are explored.
