The distribution of periphytic algae communities depends on various factors such as type substrate, level disturbance, nutrient availability and light. According to the prediction that impacts anthropogenic activity provide changes in environmental characteristics, making impacted Palm swamps related deforestation higher loads nutrients via allochthonous, hypothesis tested was: have richness, density, biomass biovolume epiphytic algae. We evaluated structure 23 Goiás State under different...
Due to the lack of knowledge in periphytic algae functional diversity patterns during successional processes floodplains, present study aimed analyze dynamics traits and species a short-term process floodplain lake. The analyzed were size class, growth form, strength attachment substratum, strategies. We evaluated these traits, considering richness, density biovolume an 18-day colonization two hydrological periods. was assessed using mean pairwise distance index (MPD). Dominant changed...
Abstract Drought events will become more frequent due the climate change. In floodplains, periphytic algae are responsible for part of primary production, principal source organic carbon deposition, play an important role in mineralization and nutrient cycling, base food web many organisms. As distribution aquatic environments is a strong indicator physical chemical conditions sites, we aimed to determine structure lentic lotic during drought uncover main local abiotic factors community...
Functional diversity–i.e., the diversity of morphophysiological characteristics species in a biological community–revolutionized ecology recent decades, shifting focus field from to ecosystems. While its ecological applications are known, adaptability other disciplines, specifically music, is explored here. We retrieved fourteen 12,944 songs by top 100 artists 2010s decade on four streaming platforms. Then, we calculated three main components functional diversity–richness, evenness, and...
A floristic study of Coscinodiscophyceae and Fragilariophyceae in the Lago dos Tigres hydrologic system is presented. Phytoplankton samples were collected with a plankton net (25 µm mesh) at 11 sampling stations, three lotic areas eight lacustrine zones. Eleven species identified; descriptions, comments, their geographic distributions for midwestern region Brazil, type environment (lentic/lotic), illustrations are provided. Among taxa found, 13 recorded first time Brazil: Aulacoseira...
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...
1. Dams on large rivers alter hydrodynamics, reduce seasonal variability and environmental heterogeneity, have significant effects river ecology. They produce less diverse environments the community composition. Knowledge about of dams functional aspects zooplankton communities is scarce. Thus, our main goal was to investigate how Tocantins River in central Brazil changed after implementation Estreito hydroelectric power plant dam. We explored relationships taxonomic beta diversity...
ABSTRACT This study aimed to survey the genus Pinnularia Ehrenberg (Bacillariophyta) in five preserved streams located three conservation units (Brasília National Park, Chapada dos Veadeiros Park and Terra Ronca State Park). Periphyton was collected different substrata during dry rainy seasons (years 2012 2013), totalizing 25 sample units. Altogether, 23 taxa were identified, being P. subanglica, angustivalva butantanum most frequent. Pebble sand richest substrates, with nine each. Among...
ABSTRACT In this study, through a rapid assessment, we evaluated differences in richness, abundance, species composition and beta diversity of Euglossini bees preserved areas altered by riverine human populations the Caxiuanã National Forest (northern Amazon). Our hypotheses were: i) diversity, abundance differ between because many are intolerant to small anthropic disturbances; ii) have higher values (species dissimilarity sites) than areas, due local changes habitat increased heterogeneity...
Abstract Evaluation of traits and functional diversity make assessments more robust when determining the nature strength relationship between species ecosystem processes. We investigated how anthropic interference physical limnological characteristics streams changed fish trait distribution their in Neotropical located Southern Brazil, encompassing Paraná, Paranapanema, Ivaí, Pirapó river basins. tested hypotheses (a) that with very low human pressure show higher values due to great variety...
