Mudanças ambientais no Cerrado Pé-de-Gigante (Santa Rita do Passa Quatro-SP): um olhar para mudanças temporais na comunidade herbáceo-subarbustiva e para o córrego Pauliceia
(Universidade Federal de São Carlos, 2022-08-25)
There are several changes that time brings to the environment. This study sought to elucidate these changes in the flora of a cerrado area (Brazilian Savanna) in the Sao Paulo state, the Gleba Cerrado Pé-de-Gigante (Vassununga ...
Padrões e processos que estruturam (meta)comunidades de bacterioplâncton, da escala local à intercontinental
(Universidade Federal de São Carlos, 2023-03-03)
Bacteria are key organisms for ecosystem functioning, being essential in biogeochemical cycles and closely related to other living organisms. Although these organisms have been studied for decades, their dynamics of ...

(Universidade Federal de São Carlos, 2023-09-29)
The zooplankton community plays a highly relevant role in temporary freshwater ecosystems. Comprising various groups of organisms such as rotifers, cladocerans, copepods, and other microcrustaceans, including Anostraca and ...
Ocorrência das espécies de carnívoros e artiodáctilos do Parque Nacional de Itatiaia e suas relações com o habitat
(Universidade Federal de São Carlos, 2020-02-17)
The biodiversity is directly or indirectly affected by chances in systems ecological systems, which modify the composition, distribution and interaction between species. Developing methods to evaluate the consequences of ...
Efeitos de distúrbios antrópicos na regeneração de plantas
(Universidade Federal de São Carlos, 2020-03-19)
Human disturbances like habitat fragmentation, edge effects, biological invasions, selective logging and grazing often alter biotic and abiotic conditions, potentially affecting plant regeneration. However, there was no ...

(Universidade Federal de São Carlos, 2020-02-17)
Mathematical modeling of macrophyte growth is a predictive tool that can be useful, for example, for planning plant population management strategies. In this study, a kinetic model was used to evaluate the growth of submerged ...
The role of fruit crop size, diversity of avian frugivores and long-term temporal variation over seed dispersal effectiveness in a neotropical savanna
(Universidade Federal de São Carlos, 2020-03-20)
Fruit crop size may be a key-trait for attracting an abundant and diverse assemblage of dispersers, possibly leading to positive outcomes for seed dispersal effectiveness (SDE). Temporal changes in resources or frugivore ...
