Biotic homogenization goes beyond the increase in taxonomic similarity among communities. It also involves loss of biological differences any organizational level (e.g., populations or communities) terms functional, genetic features. There are many ways to measure biotic homogenization, and results depend on temporal spatial scales, group, richness In freshwater ecosystems, main investigated causes correspond introduction non‐native species, damming, changes land use. However, other natural...
Abstract Ecological drift can override the effects of deterministic niche selection on small populations and drive assembly some ecological communities. We tested this hypothesis with a unique data set sampled identically in 200 streams two regions (tropical Brazil boreal Finland) that differ macroinvertebrate community size by fivefold. Null models allowed us to estimate magnitude which β‐diversity deviates from expectation under random process while taking differences richness relative...
While reducing the species richness of invaded communities is a well‐known consequence biological invasions, non‐native can also reduce variability between over time (i.e. beta diversity) in process known as biotic homogenization. Although homogenization due to common topic theoretical reviews, we believe no global meta‐analysis on effect diversity has been carried out yet. Here, systematically show that drive homogenization, but it depends realm, facet and study design. Biotic was more...
Abstract While land use intensification is a major driver of biodiversity change in streams, the nature such changes, and at which scales they occur, have not been synthesized. To synthesize how has altered multiple components stream across scales, we compiled data from 37 studies where comparative were available for species' total relative abundances locations including reference (less impacted) streams to those surrounded by different types (urban, forestry, agriculture). We found that...
Land-use and land-cover transitions can affect biodiversity ecosystem functioning in a myriad of ways, including how energy is transferred within food-webs. Size spectra (i.e. relationships between body size biomass or abundance) provide means to assess food-webs respond environmental stressors by depicting from small larger organisms. Here, we investigated changes the spectrum aquatic macroinvertebrates along broad land-use intensification gradient (from Atlantic Forest mechanized...
Abstract Body size is a key trait in ecology due to its influence on metabolism and many other life‐history traits that affect population community responses environmental variation as well ecosystem properties. The spectrum represents the relationship between abundance (or biomass) body size, independent of species identity. Size parameters, such slope or intercept, have been applied extensively indicators ecological status across multiple types. GLOSSAQUA dataset includes data from mainly...
Abstract Aim Biological diversity typically varies between climatically different regions, and regions closer to the equator often support higher numbers of taxa than those poles. However, these trends have been assessed for a few organism groups, existing studies rarely based on extensive identical surveys in climatic regions. Location We conducted standardized wadeable streams boreal (western Finland) subtropical (south‐eastern Brazil) region, sampling insects identically from 100 each...
Abstract Both β diversity and metacommunity structure vary in time space. It is necessary to examine different scales, especially the face of extreme hydrological conditions. We investigated seasonal variation Elements Metacommunity Structure [EMS] zooplankton during four years (two prolonged drought two with flood events) at spatial scales (sub‐basins floodplain; smaller larger scale, respectively). sampled 29 lakes quarterly Upper Paraná River floodplain, Brazil. estimated replacement...
The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for fishes. Our NEOTROPICAL FRESHWATER FISHES data set is to produce a large-scale inventory, covering entire from Mexico and Caribbean in north southern limits Argentina, Paraguay, Chile, Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, represented by occurrence abundance data. number of species numerous orders are as follows: Characiformes...
Abstract Community structure of many systems changes across space in different ways (e.g., gradual, random or clumpiness). Accessing patterns species spatial variation ecosystems characterized by strong environmental gradients, such as estuaries, is essential to provide information on how respond them and for identification potential underlying mechanisms. We investigated filters (i.e., gradients that can include exclude local communities), predictors geographical distance between...
Previous studies have found mixed results regarding the relationship between beta diversity and latitude. In addition, by influencing local environmental heterogeneity, land use may modify spatial taxonomic functional variability among communities causing biotic differentiation or homogenization. We tested 1) whether diversities streams within watersheds differ subtropical boreal regions 2) is related to in both regions. sampled aquatic insects 100 (Brazil) (Finland) across a wide gradient...
The effects of introduced species on native have been widely studied, however, invader-invader interactions are still poorly explored. Two non-native invasive species, the bivalve Limnoperna fortunei and submersed macrophyte Hydrilla verticillata, infested many aquatic ecosystems worldwide, they rapidly becoming nuisances in several water bodies Brazil. We tested hypothesis that H. verticillata facilitates establishment L. more than do macrophytes. surveyed mussels attached to two...
Summary Reduced species richness with increased habitat simplification is a well‐known relationship in community ecology. However, can also lead to reduction beta diversity if the loss of not random. We tested hypothesis that periphytic algae lower among simple than complex substrata. conducted field experiment using (smooth) and (rough) artificial substrata colonised by calculate each substratum type. initially estimated Jaccard dissimilarity index its turnover component. As differed...
Abstract Aim Contemporary dispersal constraints and environmental conditions are broadly recognized as significant drivers of beta diversity patterns. However, patterns may also reflect the legacy past climatic geological events. In this study, we investigated relative importance historical contemporary factors taxonomic, functional phylogenetic in Neotropical stream communities. Location The Colombian Orinoco basin. Taxon Diatoms insects. Methods We estimated using Baselga's (BAS) Podani's...
