Coexistence of competitors in spatially and temporally varying environments: A look at the combined effects of different sorts of variability

General Theory of Competitive Coexistence in Spatially-Varying Environments

The Roles of Harsh and Fluctuating Conditions in the Dynamics of Ecological Communities

Harsh conditions (e.g., mortality and stress) reduce population growth rates directly; secondarily, they may reduce the intensity of interactions between organisms. Near-exclusi...

Multispecies Competition in Variable Environments

MacArthur's consumer-resource model

Short-term instabilities and long-term community dynamics

Competition in a temporally variable environment leads to sequences of short-term instabilities that in some cases are the mechanism of long-term coexistence; in other cases the...

Mechanisms of Maintenance of Species Diversity

▪ Abstract The focus of most ideas on diversity maintenance is species coexistence, which may be stable or unstable. Stable coexistence can be quantified by the long-term rates ...

Ecology of sessile animals on sublittoral hard substrata: The need to measure variation

Abstract This paper concerns assemblages of sessile animals occupying shaded, commonly vertical hard substrata in the shallow subtidal zone. We are interested particularly in qu...
