Beta diversity patterns in zooplankton assemblages from a semiarid river ecosystem
The study of beta diversity patterns, as well as their underlying mechanisms, is fundamental for the understanding of community structure in aquatic ecosystems. Here, we aimed to investigate patterns of beta diversity in cladoceran, copepod, and rotifer assemblages in the Parnaíba and Poti rivers, along the urban perimeter of the city of Teresina (Piaui, Brazil) and to evaluate the effect of environmental, spatial, and temporal factors on beta diversity in the zooplankton assemblages. We used the Simplex analysis to represent the relative importance of replacement and abundance difference to beta diversity. The decomposition of beta diversity into its components was performed using the Ruzicka dissimilarity index, for abundance data. Distance-based Redundancy Analyses and variation partitioning were used to explore the relations between explanatory variables and beta diversity and its components. We found that beta diversity was high both spatially and temporally, and the abundance difference component showed greater relative importance than the replacement component. Environmental factors showed a greater contribution to the total explained variability in beta diversity and abundance difference, while replacement received most importance of temporal and spatial variables. Our study provides new insights on how environmental, spatial, and temporal factors shape beta diversity patterns in zooplankton assemblages in impacted aquatic ecosystems.
期刊介绍:
As human populations grow across the planet, water security, biodiversity loss and the loss of aquatic ecosystem services take on ever increasing priority for policy makers. International Review of Hydrobiology brings together in one forum fundamental and problem-oriented research on the challenges facing marine and freshwater biology in an economically changing world. Interdisciplinary in nature, articles cover all aspects of aquatic ecosystems, ranging from headwater streams to the ocean and biodiversity studies to ecosystem functioning, modeling approaches including GIS and resource management, with special emphasis on the link between marine and freshwater environments. The editors expressly welcome research on baseline data. The knowledge-driven papers will interest researchers, while the problem-driven articles will be of particular interest to policy makers. The overarching aim of the journal is to translate science into policy, allowing us to understand global systems yet act on a regional scale.
International Review of Hydrobiology publishes original articles, reviews, short communications, and methods papers.
