Ictiofauna da região da Serra da Canastra, Minas Gerais: cavernas são filtros ambientais considerando-se riqueza, diversidade e comportamento alimentar?
(Universidade Federal de São Carlos, 2021-02-04)
The subterranean (or hypogean) environment is formed by interconnected spaces of the subsoil or subsurface filled with water or air and has a marked characteristic of darkness in deeper areas and little variation in abiotic ...
Diversidade taxonômica e funcional das aves da Mata Atlântica sob influência da maior metrópole do hemisfério sul, São Paulo, Brasil
(Universidade Federal de São Carlos, 2021-03-11)
Urbanization creates one of the most irreversible forms of land use and occupation. Commonly, urbanization results in species losses and functional homogenization of bird communities, thus affecting the functioning of ...
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 ...

Environmental characteristics and trophic relationships in streams of the Atlantic Forest can interfere the ichthyofauna’s food webs which, in addition to a seasonal oscillation in the water cycle, can affect the structuring ...
Crescimento de Egeria densa (Planch.) e Salvinia molesta (Mitch.) expostas a extratos aquosos de rizomas e raízes de Typha domingensis (Pers.)
(Universidade Federal de São Carlos, 2021-09-16)
Allelopathy can be used to control invasive species. The present study aimed to identify changes in the growth and development characteristics of Egeria densa (Planch.) and Salvinia molesta (Mitch.) by evaluating the basic ...
Caracterização de microalgas e cianobactérias: abordagens ecofisiológica e biotecnológica
(Universidade Federal de São Carlos, 2022-06-29)
Microalgae are photosynthetic organisms, generally fast-growing, with simple nutritional requirements and physiological plasticity. They produce biomolecules in great variety and many with high added value. Compared to the ...
Delimitação de espécies e plasticidade fenotípica em microalgas verdes da família Selenastraceae: uma abordagem fisiológica
(Universidade Federal de São Carlos, 2020-07-13)
Recently, discussions on conservation policies at different geopolitical levels have been widely debated. Species are the main indicators for estimating biodiversity parameters, playing a key role in biodiversity records. ...
