Variação espacial e temporal do potamoplâncton ao longo do Rio Parnaíba (Piauí, Brasil): ferramentas ecológicas para o diagnóstico e monitoramento
(Universidade Federal de São Carlos, 2022-11-10)
Here we test whether the Serial Discontinuity Concept actually predicts the damming effect as a gradient break in the Continuous River Concept. Microcrustaceans (Cladocera and Copepoda) were collected at six sampling points ...
Respostas bioquímicas e morfológicas de Tilápia-do-Nilo (Oreochromis niloticus) expostas ao material particulado atmosférico sedimentável oriundo de indústrias siderúrgicas
(Universidade Federal de São Carlos, 2021-11-19)
The dust present in the atmosphere is called atmospheric particulate matter (MPA) and its composition depends on the emitting sources, which can be natural or anthropogenic. The emission and dispersion of pollutants are ...
Diversidade genética e estruturação populacional em capivaras, Hydrochoerus hydrochaeris (Linnaeus, 1766)
(Universidade Federal de São Carlos, 2022-03-08)
Decreased connectivity for species and consequently limited dispersal can be linked
to various environmental factors such as climate, dispersal barriers, or limited
dispersal. In the case of semi-aquatic organisms such ...
Fatores que estruturam metacomunidades em fitotelmos de restinga
(Universidade Federal de São Carlos, 2020-11-26)
Neotropical ecosystems harbour an imense biodiversity, covering phytophysiognomies with unique characteristics. The restingas are phyto-physiognomies characteristic of coastal regions, with hot temperatures, poor soils and ...
A comunidade de macrófitas aquáticas em reservatórios do médio e baixo Rio Tietê (SP) e em lagos da bacia do médio Rio Doce (MG)
(Universidade Federal de São Carlos, 2002-02-26)
Macrophytes have a fundamental role in the functioning of aquatic ecosystems
due to their high primary productivity, participation in the nutrient cycling, and
interactions with many other components of the system. Many ...
Propriedades ópticas da matéria orgânica dissolvida produzida por cultivos axênicos de fitoplâncton de água doce
(Universidade Federal de São Carlos, 2021-10-29)
The dissolved organic matter (DOM) is a heterogeneous mixture of molecules with
different weight and reactivity that vary spatio-temporally across aquatic ecosystems, and
is a key element of biogeochemical cycles. ...
Caracterização limnológica e inventário de diversidade das comunidades de macrófitas em cinco lagos tropicais: composição florística, biomassa e macroinvertebrados associados
(Universidade Federal de São Carlos, 2007-05-11)
In the present study five tropical lakes located in Minas Gerais State were studied. The
methodology followed the scheme of rapid inventories of aquatic diversity as used in the
AquaRAP Program. Four lakes belonging ...
