A comprehensive framework for the evaluation of metacommunity structure
This work distinguishes three distinct forms of species loss in nested structures, which should improve identifi cation of structuring mechanisms for nested patterns and demonstrates how combinations of structures at smaller spatial extents may aggregate to form Clementsian structure at larger extents.
Effects of large-scale disturbance on metacommunity structure of terrestrial gastropods: temporal trends in nestedness
Distributions of species often exhibit nested structure, such that assemblages at species-poor sites are proper subsets of taxa at more species-rich sites. Traditionally, this has been viewed as a
Elements of metacommunity structure of Paraguayan bats: multiple gradients require analysis of multiple ordination axes
An extant method to better investigate metacommunity structure for systems that respond to multiple environmental gradients is expanded and analysis of EMS along defined gradients or based on alternative ordination techniques may complement insights based on reciprocal averaging.
Metacommunity structure in a highly fragmented forest: has deforestation in the Atlantic Forest altered historic biogeographic patterns?
Despite extensive deforestation in Atlantic Forest, small mammal distributions are consistent with expectations based on historical biogeography, suggesting that anthropogenic activities have not yet greatly affected geographic distributions of emergent metacommunity structures.
Metacommunity analysis of Mexican bats: environmentally mediated structure in an area of high geographic and environmental complexity
The hypothesis that distributions of Mexican bats are defined by shared responses to environmental gradients for the entire bat metacommunity and for each of four metaensembles is tested.
Quantifying temporal variability in the metacommunity structure of stream fishes: the influence of non-native species and environmental drivers
The results suggest that the best-fit metacommunity structure of the native species can change in time in this catchment due to seasonal changes in distribution patterns, and the distribution of non-native species throughout the landscape homogenizes the temporal variability in metacomunity structure.
Ecological biogeography of Mexican bats: the relative contributions of habitat heterogeneity, beta diversity, and environmental gradients to species richness and composition patterns
Variation in bat community composition and richness in Mexico were primarily explained by local landscape heterogeneity and environmental factors, indicating that bats respond directly to habitat composition and structure.
The role of stochastic processes in producing nested patterns of species distributions
Nestedness has received considerable attention in community ecology and conservation biology from both theoretical and empirical perspectives. This has lead to the creation of various metrics and
The Role of Salinity in Structuring Fish Assemblages in a Prairie Stream System
Examination of fishery surveys from 1954 to 1957 provides compelling evidence that salinity has been a dominant and persistent factor in affecting the structure of stream-fish assemblages for the past 50 years.
Discrimination and classification of foraging paths produced by search-tactic models
A suite of search-tactic models was developed to simulate possible searching behaviors of mobile organisms so that inferences can be made about their decision mechanisms, and to determine the extent to which different models produce paths that approximate a globally optimal solution.
