Temperature effects on photosynthesis in gametophytic and sporophytic stages of the freshwater red alga Sirodotia delicatula (Rhodophyta, Batrachospermales) under a global warming perspective
(2018-01-01)
The increase in Earth's global mean temperature due to human influence has become a major concern, with ecological consequences already being reported around the world. In tropical streams, benthic red algae belonging to ...
Different scales determine the occurrence of aquatic macrophyte species in a tropical stream
(2021-01-01)
Distributions of aquatic macrophyte species are commonly associated with water chemistry characteristics. However, other environmental factors that can lead to the occurrence of aquatic plants in lotic ecosystems, such as ...
Functional feeding habits of Chironomidae larvae (Insecta, Diptera) in a lotic system from Midwestern region of São Paulo State, Brazil
(2008-08-01)
Functional feeding habits of Chironomidae larvae (Insecta, Diptera) in a lotic system from Mid-western region of São Paulo State, Brazil were analyzed. Collectors were the dominant organisms, repre-sented by genera Chironomus, ...
When roads cross streams: fish assemblage responses to fluvial fragmentation in lowland Amazonian streams
(Soc Brasileira Ictiologia, 2020-01-01)
Roads affect biodiversity by increasing mortality rates, habitat loss, and natural landscape fragmentation. Poorly installed culverts can impound streams, changing the environmental conditions, and affecting aquatic ...
Effect of atypical rainfall on lotic zooplankton: comparing downstream of a reservoir and tributaries with free stretches
(Int Soc Tropical Ecology, 2012-05-01)
To contribute to the knowledge of lotic zooplankton from dammed and free stretches, we tested the hypothesis that the ecological attributes are different between these environments, which are subjected to several effects ...
Modification of Lotic Environments for Open Pit Coal Extraction: Effects on Biota and Recommendations
(Univ Nac Colombia, Fac Ciencias, Dept Biol, 2018-01-01)
Open coal mining will cause a series of modifications to different lotic environments in Colombia. In this paper we analyzed the case of an open pit coal mine located in the Department of La Guajira, Colombia, focusing on ...

Riqueza, abundância e sazonalidade de comunidades de macroalgas em diferentes escalas espaciais em riachos da região centr-sul do estado do Paraná
(Fundacao Zoobotanica Rio Grande Sul, Museu Ciencias Naturais, 2014-07-31)
The structure and seasonality of benthic macroalgal communities of lotic ecosystems was evaluated at different spatial scales of observation in streams of the central-southern region of Parana State. Samples were collected ...
