Effects of land use on environmental conditions and macrophytes in prairie lotic ecosystems
(Elsevier Gmbh, 2012-07)
Fluvial hydrosystems are environments with large landscape to water surface ratio and therefore particularly vulnerable to changes in land use. We analysed the connection of environmental conditions in 31 prairie streams ...
Alpha And Beta Diversity Of Freshwater Meiofauna At Different Spatial Scales In A Neotropical Lotic System
(CSIRO PublishingClayton, 2017)
Sponge spicules indicate Holocene environmental changes on the Nabileque River floodplain, southern Pantanal, Brazil
(2013-01-01)
Sponge spicules are siliceous microfossils that are especially useful for analysis of sandy fluvio-lacustrine sediments. Sponge spicules in a long sediment core (~550 cm below surface), consisting of fine sand, sandy silt, ...
Algas de ambientes lóticos en el Estado de Morelos, México

UV-radiation effects on photosynthesis, photosynthetic pigments and UV-absorbing substances in three species of tropical lotic macroalgae
(Brazilian Soc Plant Physiology, 2018-09-01)
Freshwater algae inhabiting shallow waters are most effectively affected by UV radiation. The aim of this study was to analyze the photosynthetic performance (parameters derived of chlorophyll fluorescence), chlorophyll a ...
The stream tadpoles of Rhinella Rumbolli (Anura: Bufonidae)
(Herpetologists League, 2014-02)
The Rhinella veraguensis group is likely a paraphyletic assemblage that contains 16 species of Andean toads. To date, descriptions are available for larval stages of only three species, all of which possess a distinct ...
Resistance, resilience, and patchiness of invertebrate assemblages in native tussock and pasture streams in New Zealand after a hydrological disturbance

Monogenéticos (Dactylogyridae) parasitando brânquias de Salminus hilarii de uma represa Neotropical, Brasil
(2013-10-01)
With the aim of creating an inventory of the metazoan gill parasites of Salminus hilarii in the Taquari River, state of São Paulo, Brazil, five species of monogeneans (Anacanthorus contortus, A. bicuspidatus, Annulotrematoides ...
Diversity and structure of Ephemeroptera, Plecoptera and Trichoptera (Insecta) assemblages from riffles in mountain streams of Central Brazil
(Sociedade Brasileira de Zoologia, 2007-06-01)
A diversidade e a estrutura de comunidades de Ephemeroptera, Plecoptera e Trichoptera (EPT) em riachos do Brasil Central (Serra dos Pireneus, Pirenópolis, Estado de Goiás) foi investigada. Dados de abundância de EPT foram ...
Light-related photosynthetic characteristics of freshwater rhodophytes
(Elsevier B.V., 2005-07-01)
Photosynthetic characteristics in response to irradiance were analysed in 21 field and culture populations of thirteen freshwater red algal species applying two distinct techniques (chlorophyll fluorescence and oxygen ...
