ABSTRACT Biotic homogenisation is defined as decreasing dissimilarity among ecological assemblages sampled within a given spatial area over time. differentiation, in turn, increasing Overall, changes the dissimilarities (termed ‘beta diversity’) an increasingly recognised feature of broader biodiversity change Anthropocene. Empirical evidence biotic and differentiation remains scattered across different ecosystems. Most meta‐analyses quantify prevalence direction beta diversity, rather than attempting to identify underlying drivers such changes. By conceptualising mechanisms that contribute or composition space, environmental managers conservation practitioners can make informed decisions about what interventions may be required sustain predict potential outcomes future disturbances. We systematically reviewed synthesised published empirical for terrestrial, marine, freshwater realms derive conceptual models explain diversity. pursued five key themes our review: ( i ) temporal change; ii disturbance regime; iii connectivity alteration species redistribution; iv habitat v trophic interactions. Our first model highlights how occur function local (alpha) diversity regional (gamma) independently invasions losses due occurrence assemblages. Second, magnitude depends on interaction between variation (patchiness) (synchronicity) events. Third, context redistribution, divergent have dispersal characteristics, associated with also strongly alpha gamma prior invasion. Fourth, positively linked variability, when heterogeneity decreases increases, respectively. Fifth, interactions influence via modification, disease, consumption (trophic dynamics), competition, by altering ecosystem productivity. synthesis multitude cause more less spatially similar (taxonomically, functionally, phylogenetically) through consider studies should aim enhance collective understanding systems clarifying driving focusing only reporting per se .

In this study, we explored formation spatial differentiation in zooplankton context urbanization by using instead temporal methods reveal intensive Huaihe River Basin. The results showed that decreased with increasing level, composition areas different levels was significantly different.

Multi-scale analysis of functional plankton diversity in floodplain wetlands: Effects of river regulation

The Science of The Total Environment, Journal Year: 2019, Volume and Issue: 667, P. 338 - 347

Published: Feb. 25, 2019

Riverine floodplains are among the most diverse and dynamic ecosystems, but river regulation measures have altered natural hydrological regime threatening their ecological integrity. We compared spatial patterns of phyto- zooplankton functional diversity environmental heterogeneity between floodplain wetlands located in free-flowing impounded stretches Danube River (Austria). included two nested scales (different habitats water sections within wetland areas) contrasting conditions (post-flood, no flood). Environmental was lower stretch than ones. At post-flood conditions, increased alpha rotifers microcrustaceans decreased beta phytoplankton occurred as to one. Beta higher similar across stretch. Regarding composition, hosted more homogeneous communities, some traits were nearly absent. Our results indicate that affected by altered, highlighting major role gradient lateral connectivity level fluctuations drivers for planktic floodplains. This study contributes with essential knowledge optimize restoration conservation riverine ecosystems.

Abstract The restoration of degraded areas and the creation artificial ecosystems have partially compensated for continuing loss natural wetlands.
