Impact of environmental change on ecological communities.
… concepts, including non-analogous communities, biotic homogenization, metacommunities and climate tracking responses at an appropriate meso-sca1e. Although no evidence for nonanalogous communities was found, biotic homogenization was supported and appeared to be caused by increased nitrogen and …

Weaving through the matrix: investigating the influence of urban land use on weaver bird movements into and out of Cape Town wetlands
… human land use, causes local extinctions, biotic homogenization and fragmentation of natural habitats. Understanding how the nature of the urban matrix affects the species residing within a city’s fragmented habitats is an important founding component of urban conservation. This study …

Taxonomic homogenization of plant communities in Illinois wetlands and the role of wetland compensation
Biotic homogenization, a process by which β-diversity erodes, represents a severe threat to biodiversity. Wetlands are especially susceptible to biotic homogenization; however, this process has rarely been documented and represents just one of many possible outcomes of compositional change. …

Abundance Trends and Drivers of Change in Freshwater Fish Communities of the New River Basin
… across contributing watersheds and widespread biotic homogenization and native species declines over the past 60+ years. These declines include reductions in unique communities and endemic species provided little consideration or protection under current conservation law. I suggest potential …

The structure of global invasive assemblages and their relationship to regional habitat variables: converting scientifically relevant data into decision relevant information
… of a non-random structured process driven by biotic and abiotic characteristics of the region. The most commonly used clustering technique for grouping regional pest assemblages is a self-organizing map (SOM), which is an artificial neural network algorithm. Two other clustering methods that …

Patterns of temporal changes in species composition and diversity in island ecosystems
… Thus, it is important for ecologists studying biotic homogenization to quantify also changes in functional beta diversity. Positive correlation among different components of diversity was detected among some of their facets. It is indeed crucial to determine whether the observed species …
