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 ...
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 ...
