1. Disturbance as a factor in breaking dormancy and enhancing invasiveness of African grasses in a Neotropical Savanna
The Cerrado is threatened by wildfires and invasive species. We aimed to evaluate in laboratory conditions whether temperature fluctuation at the soil surface, resulting from the absence of vegetation due to fire, can affect the germination of Urochloa decumbens and U. brizantha, two invasive African grasses. Seeds of both species were submitted to simulatio

2. Modelos de distribuição de espécies invasoras : tendências e aplicações
Modelos de distribuição de espécies, também conhecidos como modelos bioclimáticos ou modelos de nicho ecológico, têm sido aplicados em inúmeras questões ecológicas, incluindo espécies invasoras. Essa tese identificou as principais tendências e lacunas de estudos sobre o uso de modelos de distribuição de espécies para predizer a distribuição

3. Avaliação do efeito de borda sobre a vegetação do cerrado stricto sensu inserido em matriz de pastagem / Edge effects on plant community of cerrado sensu stricto inserted into a matrix of pasture
From the Brazilian biomes, the Cerrado has been the most widely and rapidly converted to agribusiness in recent years. The expansion of agricultural frontier over the Cerrado domain resulted in thousands of small fragments embedded in matrices of low similarity, causing a series of negative impacts on the natural ecosystem. Habitat fragmentation is considere

4. Management efficiency to control two invasive grasses in cerrado fragments, in São Paulo State / Eficiência do manejo no controle de duas espécies de gramíneas invasoras em Cerrados Paulistas
Several African grasses introduced in the Brazilian savannas for cattle feeding became invasive, and now they severely threaten the native biodiversity. It is, therefore, fundamental to look for effective methods to control them. The objective of this study was to evaluate the efficiency and cost of different management techniques to control the invasive gra
