Does the nature and persistence of a substrate at a mesohabitat scale matter for Chironomidae assemblages? A study in two perennial mountain streams in Patagonia, Argentina
(University Of Arizona, 2012-05)
Chironomid substrate-specific associations regarding the nature (organic-inorganic) and stability (stable-unstable) of different habitats were investigated at two low order Patagonian streams, during high and low water ...
Macroalgae of a stream in southeastern Brazil: composition, seasonal variation and relation to physical and chemical variables
(Kluwer Academic Publ, 1991-05-01)
Macroalgal seasonality was studied monthly in a second-order stream in the north-west of São Paulo State, S.E. Brazil. Seasonal variation was based on frequency and percentage cover. Seven species were found during the ...
Feeding selectivity of ichthyofauna in a tropical stream: space-time variations in trophic plasticity
(Akademiai Kiado, 2011-06-01)
In studies on the partitioning of resources, one issue which has been largely neglected is the change in feeding habits based on the availability of food in the environment, an aspect which is dealt with here with regard ...

The importance of substrate size and interstitial space in the microhabitat selection by the stream-dwelling catfish Hatcheria macraei (Actinopterygii, Trichomycteridae)
(Springer, 2013-01)
The study tests whether diurnal microhabitat use by Hatcheria macraei depends upon specific environmental parameters and/or the abundance of other fish. We carried out a 1-year field study in a low-order river of northern ...
Multi-scale assessment of forest cover in an agricultural landscape of Southeastern Brazil: Implications for management and conservation of stream habitat and water quality
(Elsevier B.V., 2018-02-01)
Forest cover has important functions for streams. Consequently, deforestation and forest degradation due to agricultural activities tend to have negative impacts on stream ecosystems. We related forest cover to stream ...
Macroinvertebrados em córregos de baixa ordem sob diferentes usos do solo no estado de São Paulo: subsídios para o biomonitoramento
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERN, 2008-07-04)
The environmental monitoring assesses the state of preservation of aquatic ecosystems, providing information for the development of strategies for management, conservation of natural areas and plans for recovery of degraded ...
