Influence of regional factors on zooplankton structure in a saline lowland river: the Salado River (Buenos Aires province, Argentina)
Knowledge of regional factors influencing zooplankton structure in a semiarid river must include both the main channel and any tributaries in order to identify spatial and temporal patterns along with the main factor that ...
Occurrence and distribution of plankton-associated and free-living toxigenic Vibrio cholerae in a tropical estuary of a cholera endemic zone
Cholera epidemics are thought to be influenced by changes in populations of estuarine Vibrio cholerae. We investigated the abundance and distribution of this bacterium, as ‘‘free-living’’ (\20 lm fraction) and associated ...
Spatial distribution and shell utilization in three sympatric hermit crabs at non-consolidated sublittoral of estuarine-bay complex in São Vicente, São Paulo, Brazil
The objective of the present study was to characterize the spatial distribution and shell utilization of three hermit crab species in the estuarine-bay complex of São Vicente, São Paulo State, Brazil. Monthly samples were ...
Arbuscular mycorrhizal fungi in saline soils: Vertical distribution at different soil depth
(Sociedade Brasileira de Microbiologia, 2014)
Nutrient, chlorophyll and zooplankton seasonal variations on the southern coast of a subtropical saline lake (Mar Chiquita, Córdoba, Argentina)
(EDP Sciences, 2016-05)
Mar Chiquita is the largest salt lake in South America. Because of its rich and diverse biodiversity, it has been designated a world site of the Ramsar Convention on Wetlands. Despite its importance, its limnological ...
Molecular analysis of enrichment cultures of ammonia oxidizers from the Salar de Huasco, a high altitude saline wetland in northern Chile
(SPRINGER TOKYO, 2008-05)
We analyzed enrichment cultures of ammonia-oxidizing bacteria (AOB) collected from different areas of Salar de Huasco, a high altitude, saline, pH-neutral water body in the Chilean Altiplano. Samples were inoculated into ...
Aplicação de métodos voltamétricos de análise na especiação de cromo, selênio e antimônio em matrizes salinas
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2010-02-04)
This work aimed to explore the speciation analysis of chromium, selenium and antimony, elements of clinical and geochemical relevance, in the saline samples seawater, hydrothermal fluid and hemodialysis fluid. These samples, ...
