A bioacústica como ferramenta adicional para o estudo da estrutura e dinâmica de uma comunidade de aves em mata estacional semidecidual
(Universidade Federal de São Carlos, 2020-03-06)
Understanding the dynamics and structure of bird communities in forest fragments provide us important data for conservation. The classification of the community regarding trophic categories and strata is one of the most ...
Conquistando o ambiente urbano: valor adaptativo e comportamento parental nos ninhos de Turdus leucomelas (Aves, Turdidae) em edifícios
(Universidade Federal de São Carlos, 2020-03-06)
Reproduction is a crucial stage of the life cycle of all species, and the related energetic conflicts are especially important on species that present intense parental care, such as altricial birds. Nest site selection is ...
Morte celular programada em microalgas verdes cocoides e seus possíveis efeitos ecológicos
(Universidade Federal de São Carlos, 2020-03-11)
Programmed cell death may have important intra and inter-specifics effects in phytoplanktonic populations, and consequently in the ecology of freshwater ecosystems. However, before any ecological studies or evolutionary ...
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 ...
Invasão do Cerrado pela Braquiária (Urochloa decumbens): impacto na predação de sementes e potencial de disseminação por formigas
(Universidade Federal de São Carlos, 2020-03-20)
Biological invasions are a threat to native biodiversity. African grasses (such as brachiaria, Urochloa decumbens) are present in almost all Cerrado fragments, and is one one of the main challenges in the conservation of ...
O papel das macrófitas aquáticas nos processos erosivos, qualidade da água e dinâmica de gases do efeito estufa no Pantanal norte
(Universidade Federal de São Carlos, 2020-03-06)
In wetlands such as the Pantanal, aquatic macrophytes tend to stabilize and perform relevant ecological functions through water level fluctuations that determine the structure and dynamics of the environment. This study ...
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 ...
Estudo da fisiologia do crescimento, produção de biomoléculas e fotossíntese em 30 espécies de microalgas verdes de água doce
(Universidade Federal de São Carlos, 2020-06-12)
Studies on the physiology and photosynthesis of microalgae are an essential contribution to projects aimed at carbon fixation and biomass production for commercial purposes. Green microalgae (Chlorophyta stricto sensu) ...
Sexagem molecular em Xenarthras, avaliação espaço-temporal de atropelamentos em tamanduás e diversidade genética em Myrmecophaga tridactyla: implicações para conservação
(Universidade Federal de São Carlos, 2020-07-10)
It is expected that species that live in highly fragmented environments and have biological characteristics such as specialized diet, long generation time and low fecundity, tend to suffer more from anthropic impacts, ...
Efeitos da temperatura e da contaminação de rejeitos da mineração no crescimento e na fisiologia de Ricciocarpos natans (L.) Corda
(Universidade Federal de São Carlos, 2020-06-10)
In recent years, the contamination of Brazilian water resources by metals contained in mining waste has become frequent and, in addition, another environmental factor that must also be considered, concomitantly, is the ...
