Ecological distribution of stream macroalgae in different spatial scales using taxonomic and morphological groups
(Sociedade Botânica de São Paulo, 2012-01-01)
We examined the ecological distribution of macroalgal communities in streams using species groups (taxonomic units = algal phyla, and morphological = morphological types) with similar structures and functions instead of ...
Spatial variations at different observational scales and the seasonal distributions of stream macroalgae in a Brazilian subtropical region
(Sociedade Botânica de São Paulo, 2012-01-01)
We examined the relationships between environmental variations in lotic ecosystems with the seasonal dynamics of macroalgae communities at different spatial scales: drainage basin of two rivers (Rio das Pedras and Rio ...
Species of the genus Oedogonium in streams in the northwest region of Sao Paulo State, Brazil
(Museu Nacional-univ Federal Do Rio De Janeiro, 2008-01-01)
In the northwest region of the Sao Paulo State, the genus Oedogonium (Oedogoniaceae, Chlorophyta) is very common and abundant in lotic environments. In running waters, where specimens usually occur only in vegetative state, ...
Helminths of Steindachnerina insculpta in two distinct stretches of the Taquari River, state of Sao Paulo, Brazil
(Brazilian Coll Veterinary Parasitology, 2013-10-01)
The purpose of this study was to evaluate the helminth fauna of Steindachnerina insculpta in the Taquari River, a tributary of the Jurumirim reservoir in the state of Sao Paulo, and to investigate whether some helminth ...
Short-term effects of visitor trampling on macroinvertebrates in karst streams in an ecotourism region
(Springer, 2014-03-01)
In order to evaluate the potential risks of human visitation on macroinvertebrate communities in streams, we investigated the effect of trampling using two short-term experiments conducted in a Brazilian ecotourism karst ...
Importance of reservoir tributaries to spawning of migratory fish in the upper parana river
(Wiley-Blackwell, 2015-03-01)
Regulation of rivers by dams transforms previously lotic reaches above the dam into lentic ones and limits or prevents longitudinal connectivity, which impairs access to suitable habitats for the reproduction of many ...
The relationship between macroalgal morphological complexity and hydraulic conditions in stream habitats
(Springer, 2015-03-01)
The effects of habitat complexity have been considered important factors for the evolution of morphological complexity in organisms. We assessed the possible relationship between hydraulic niche conditions and the morphological ...
Length/weight relationship and condition factor of Macrobrachium jelskii (Miers, 1877) and M. brasiliense (Heller, 1862) (Decapoda, Palaemonidae) in two locations in the state of São Paulo
(Sociedade Brasileira de Carcinologia, 2017)
Abstract This study describes the weight vs. carapace length relationship and provides the total and monthly condition factor values for populations of Macrobrachium jelskii (Miers, 1977) and M. brasiliense (Heller, 1868) ...
The importance of free stretches in a dammed river to the maintenance of Schizodon intermedius populationsA importância de trechos livres de barramento em ambientes represados na manutenção de populações de Schizodon intermedius
(2019-02-03)
This paper focuses on to evaluate the importance of a free stretches upstream of a Neotropical reservoir for the maintenance of Schizodon intermedius populations, a medium size migratory species and important fisheries ...
First record of plastic ingestion by an important commercial native fish (Prochilodus lineatus) in the middle Tiete River basin, Southeast Brazil
(Revista Biota Neotropica, 2020-01-01)
This is the first study to report the plastic ingestion by Prochilodus lineatus in Brazilian fluvial ecosystems. We examined 32 individuals collected in two contrasting lotic environments: the highly polluted Tiete River ...
