1. O valor de corredores florestais para a conservação de aves em paisagens fragmentadas / The value of forest corridors to bird conservation in fragmented landscapes
Habitat loss and fragmentation are major threats to biodiversity. Habitat corridors linking remnants are a popular strategy to reduce the negative effects of habitat loss and fragmentation. However, the evaluation of the effectiveness of corridors in conservation is limited by lack of empirical evidence, especially in the neotropics. In this thesis we empiri

2. Efetividade de dispersão por antas (Tapirus terrestris) : aspectos comportamentais de deposição de fezes e germinação de sementes
Maior mamífero terrestre neotropical, a anta (Tapirus terrestris) possui hábitos solitários. É classificada como herbívora-frugívora, ingerindo grande quantidade de frutos com sementes de diversas espécies. Potencialmente, a anta é considerada um dispersor de sementes. Nesse trabalho, estudamos aspectos comportamentais da formação de latrinas por a

3. Genetic consequences of population subdivision: the marsupial Micoureus paraguayanus (Mammalia: Didelphimorphia) as a case study
Habitat fragmentation may cause population subdivision, affecting genetic variation, leading to heterozygosity loss and increased inbreeding, and contributing to population extinction. However, some genetic models have shown that under some conditions, population subdivision can favor heterozygosity and allelic diversity, and small populations may adapt to i

4. Dispersing chemicals in the granulometric analysis of latosols / Dispersantes químicos na análise granulométrica de latossolos
The most accurate textural analysis result is dependent on the soil samples complete dispersal and maintenance of the dispersed phases stability. The solutions high pH can be considered to be determinant in the dispersion of soils with pH dependent loads. Under the same pH and osmotic pressure conditions, the higher the ions ionic hydrated radius, the more e
