WebJul 5, 2024 · Here, we used a novel adaptation of Whittaker’s (1960) 13 spatial-scale explicit diversity partition to assess the prevalence of biotic homogenisation and differentiation, and associated changes in species richness at smaller and larger spatial scales. 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 …

WebNov 29, 2012 · Biotic homogenization of plant and animal communities is a common result of ecosystem conversion, but it is unique for microorganisms. Biotic homogenization can occur through the loss of taxa with restricted geographic ranges (“endemic” taxa), the invasion of taxa with broad ranges, and/or an increase in the ranges of existing species … 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. city farm perth wa

WebDec 15, 2008 · Abstract. Biotic homogenization is the process by which species invasions and extinctions increase the genetic, taxonomic or functional similarity of two or more locations over a specified time ... WebWhat is known is that across all empirical studies, biotic homogenisation was reported more often (odds ratio = 1.6) than biotic differentiation or no change in community similarity through time (Fig. 2). A closer look at the data reveals that the overall homogenisation effects were driven largely by studies in the Nearctic region, whereas the ... dictionary\\u0027s ygWebThey also alter the structure and functioning of ecosystems, lead to biotic homogenisation, and eventually threaten human economies and health.

"Biotic homogenization is the process by which two or more spatially distributed ecological communities become increasingly similar over time. This process may be genetic, taxonomic, or functional, and it leads to a loss of beta (β) diversity.
