Abstract Evaluation of the relative influences environmental and spatial processes in structuring aquatic metacommunities is an essential first step for understanding how these factors govern species distributions affect temporal variability community structure. Such has many causes consequences at different scales. In case phytoplankton metacommunities, both sorting mass effect are likely to be important patterns biomass distribution on large We investigated components a scale, consisting...
Abstract Lotic environments are among the most vulnerable aquatic ecosystems, and changes occurring in them happen faster than our capacity to measure impacts, with choice of community attributes that best reflect these disturbances still unclear. In this study, we evaluated response phytoplankton species traits along a gradient urbanization lowland streams. To do this, sampled nine streams three areas classified as densely populated (DP), low (LP), rural (RA) during four seasons (n = 108),...
ABSTRACT Run‐of‐river dams (RORs) are often considered less environmentally damaging than storage dams, but information on their impact regional biodiversity is scarce. In particular, the effects of RORs species commonness largely unknown. this study, we assessed impacts ROR phytoplankton and zooplankton in largest tributary Amazon River. We investigated changes environmental heterogeneity, richness beta diversity examined whether these varied with commonness. shift composition heterogeneity...
An intensively debated issue in ecology is whether the variations biodiversity patterns of different biological groups are congruent space and time. In addition, ecologists have recognized necessity accounting for both taxonomic functional facets when analysing spatial temporal congruence patterns. This study aimed to determine how cross-taxon beta diversity varies across time, using data from four floodplains at a continental scale. Our general hypothesis was that between aquatic groups,...
ABSTRACT The upper Paraná river floodplain is a strategic area for the Brazilian biological and environmental patrimony contains several conservation units. We aimed to record occurrence geographic distribution of microalgae in this during 30 years research carried out by Center Research Limnology, Ichthyology Aquaculture - State University Maringá. consulted 80 publications (national international journals books published from 1986 2016). considered only works that referenced algae at...
Abstract Aim: To evaluate the influence of upstream reservoirs on temporal and spatial variation phytoplankton community in Paraná River channel importance its main tributaries reducing oligotrophication process along this stretch river. Materials Methods Sampling physical chemical variables was performed quarterly between August 2013 May 2015, mouth tributaries, at located downstream Porto Primavera reservoir backwaters Itaipu reservoir. summarize density relation to variables, we a...
Abstract Aim: The objective of this study was to evaluate the efficacy phytoplankton functional groups as indicators environmental conditions in floodplain rivers and lakes with different trophic state connectivity degree Paraná River. Phytoplankton (FGs) cluster sensitive species variation can be an alternative for monitoring. Methods Samples were performed quarterly from 2010 2013 Ivinhema, Baia Rivers three permanently connected each river. Results 419 taxa identified, those that had...
Abstract Aim: We analyzed the temporal distribution (dry and rainy periods) of phytoplankton functional groups (biovolume) from lakes connected to dammed (S1 - Paraná River) non-dammed rivers (S2 Baia River S3 Ivinhema in upper floodplain, Brazil. also determined drivers community assemblage. Methods Phytoplankton environmental variables samplings were performed quarterly dry (2000 2001) (2010 2011) periods. classified species into seven morphological based (MBFG). used analysis variance...
Protection areas favor diversity as they decrease the impact of anthropic disturbance on biological communities. Testing its effects diverse communities is a pivotal step to understand how different trophic levels react such management and conservation strategies. Here, we used data collected from 1993 2018 subtropical floodplain evaluate effect installation protection zone taxonomic functional phytoplankton community. We showed that park had positive aquatic community, mainly related...
Abstract Run-of-river (ROR) dams, often perceived as having minimal environmental impact, can induce significant hydrodynamic changes that alter aquatic ecosystems. We investigated the impacts of an ROR dam on Madeira River, largest Amazon tributary, focusing phytoplankton communities, their ecological implications, and related factors. Our study examined in biomass factors (using General Linear Mixed Models - GLMM), species composition PERMANOVA) before after damming, both main channel...
