Diversity Assessment Of Lotic Macroalgal Flora By The Application Of Taxonomic Distinctness IndexAvaliação Da Biodiversidade De Macroalgas Lóticas Pela Aplicação Do índice De Distintividade Taxonômica
(Universidade Estadual de Campinas UNICAMP, 2016)
LONGITUDINAL DISTRIBUTION OF MACROALGAE IN 2 TROPICAL LOTIC ECOSYSTEMS FROM SOUTHEASTERN BRAZIL
(E Schweizerbart'sche Verlags, 1995-11-01)
Macroalgal species richness and diversity were analysed along a longitudinal profile in small and large scales during Spring, Fall and Winter, respectively in a small stream and a mid size river in the northwest region of ...
Methods of sampling benthic invertebrates in lotic habitats: A spatial and temporal evaluationMétodos de amostragem de invertebrados bentônicos em ambientes lóticos: Uma avaliaçao espacial e temporal
(2019-01-01)
Aim: We compared the effectiveness of two sampling devices, the Surber sampler and the D-frame net, commonly used in the analysis of invertebrate fauna structure in biomonitoring programs. These programs use the response ...
Trends in planktonic copepod diversity in reservoirs and lotic stretches in a large river basin in South America
(Csiro Publishing, 2014-01-01)
Copepod assemblages were analysed across La Plata River basin, the second largest in South America. High values of species richness and Shannon-Wiener diversity were found in the lower Parana River, the main and largest ...
Reproductive seasonality of fishes from a lotic stretch of the Grande River, high Paraná river basin, Brazil
(Instituto Internacional de Ecologia, 2005-08-01)
Foi investigada a correlação entre nível hidrológico, pluviosidade e temperatura e reprodução de peixes num trecho lótico do rio Grande, abaixo da barragem de Volta Grande. Para a captura, realizada com redes de espera, ...
Modeling the species richness and abundance of lotic macroalgae based on habitat characteristics by artificial neural networks: a potentially useful tool for stream biomonitoring programs
(2017-08-01)
One of the major challenges in stream ecology is the development of computational models that can predict aspects of the community structure of organisms from these ecosystems when they are subject to natural or artificial ...
Assessing the diet and trophic niche breadth of an omnivorous fish (Glanidium ribeiroi) in subtropical lotic environments: Intraspecific and ontogenic responses to spatial variations
(2019-01-01)
The diet of Glanidium ribeiroi was investigated in lotic stretches downstream from a cascade of reservoirs to determine how it responds to intraspecific and environmental variations. Monthly sampling was performed from ...
Phytophilous macroinvertebrate diversity in headwater streams in mountain grasslands in Córdoba, ArgentinaDiversidad de macro invertebrados fitófilos en arroyos de cabecera en pastizales de altura en Córdoba, Argentina
(Universidad Nacional Autónoma de México. Instituto de Biología, 2017-12)
Macrophytes play an important role in lotic systems increasing habitat heterogeneity and providing food and shelter for wildlife. The aim of the study was to analyze the structure and composition of the invertebrate community ...
Effects of anthropogenic impacts on benthic macroinvertebrates assemblages in subtropical mountain streams
(2013-12)
The nature of the riparian and surrounding landscape has been modified by anthropogenic activities, which may subsequently alter the composition and functional structure of macroinvertebrate assemblages. The effect of these ...
Influence of hydrological changes on the fish community in two lotic environments of the Middle Paraná Floodplain, Argentina
(Springer, 2014-06)
Temporal variations of fish abundance and species richness in two sites of a secondary channel of the Middle Parana´ Floodplain (Argentina) have been analyzed from 2010 to 2012. Relationships of these ecological attributes ...
