Avifauna em remanescentes de Mata Atlântica no Sul da Bahia: sensibilidade e conservação
(Universidade Federal de São Carlos, 2021-03-16)
The south of Bahia stands out in the conservationist scenario, hosting the largest Atlantic Forest remnants. Consequently, the region has a rich biodiversity, containing taxa that have already been extinct in most of their ...
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 ...
Modelagem da estrutura trófica da comunidade biótica de uma bacia costeira em Bertioga – SP
(Universidade Federal de São Carlos, 2022-08-29)
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 ...
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. ...
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 ...
Qualidade do detrito na perda de massa do material particulado de eichhornia crassipes (mart.) solms sob efeito da temperatura
(Universidade Federal de São Carlos, 2019-12-12)
Carbon cycling of macrophytes in aquatic ecosystems occurs both by the characteristics of the environment (extrinsic properties) and by the different characteristics of their debris (intrinsic properties). So, in this ...
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 ...
Physiological responses of chlorophyta microalgae under environmentally relevant copper concentrations: biomolecules, oxidative stress and photosynthesis
(Universidade Federal de São Carlos, 2022-02-28)
Microalgae require copper (Cu) in trace levels for their growth and metabolism. It is a vital component of certain metalloproteins, participates in the photosynthetic process, and catalyzes various redox reactions. Although ...
