Biotic homogenisation
WebFeb 17, 2024 · INTRODUCTION. Beta diversity refers to the spatial variation in species composition (Magurran, 2004).It is an important metric because it can inform our understanding of biodiversity change and its consequences for communities and ecosystems (Mori et al., 2024).For example, beta diversity can increase the capacity of … WebDec 2, 2016 · 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. Additionally, it has been suggested that the …

WebUrbanization is a major cause of biotic homogenization, once it modifies species habitat and creates new environments in which only a few species are able to survive. However, many authors propose that planned green areas within the bounds of urban centers work real islands, providing shelter for several animal species.
