1. More is not always better: responses of the endemic plant Vellozia nanuzae to additional nutrients
ABSTRACT Soil nutrients are one of the main drivers of plant species composition and distribution, mainly due to the role they play in plant survival and reproductive success. However, the nutritional requirements of plants inhabiting their native ecosystems are still poorly known. This is the case for most species of campo rupestre vegetation, which are fou

2. Morphological and genetic perspectives of hybridization in two contact zones of closely related species of Petunia (Solanaceae) in southern Brazil
ABSTRACT Interspecific hybridization has several consequences for parental species, from blurring species limits to the emergence of new taxa. Petunia axillaris and P. exserta occur in sympatry in southernmost Brazil and naturally hybridize despite their different pollination syndromes and habitat requirements. We employed genetic and morphological analyses

3. Maternal habitat affects germination requirements of Anabasis setifera, a succulent shrub of the Arabian deserts
The effects of maternal habitat on light and temperature requirements during germination were assessed for the succulent desert shrub Anabasis setifera. Seeds were collected from the Mediterranean habitats of Egypt and the hyper-arid subtropical habitats of the United Arab Emirates (UAE). Seeds from the two populations were germinated in three temperature tr

4. Área de uso e seleção de habitats por veado-catingueiro (Mazama gouazoubira; Fisher, 1814) no Pantanal de Nhecolândia-MS / Area of use and habitat selection by brown brocket deer (Mazama gouazoubira, Fisher, 1814) in the Nhecolândias Pantanal-MS
The physique space is a major dimensions of the niche of a species as the way is used for determining a series of interactions with the ecological environment. In the present study we estimated the size of the home range and habitat selection considering two scales of selection (second and third order) by brown brocket deer (Mazama gouazoubira) in the sub-re

5. Distribuição, nicho potencial e ecologia morfológica do gênero enyalius (squamata, leiosauridae) : testes de hipotéses para lagartos de florestas continentais brasileiras
In the first chapter, we saw that the main factors affecting the Enyalius¿ geographical distribution were the annual mean temperature, latitude, and the mean diurnal temperature, which indicates a possible thermal adaptation as a base to explain the group distribution. Enyalius distribution was reflected in the morphological geographical variation, as demon

6. Determinantes ecológicos do risco de extinção: abundância local, amplitude de nicho, capacidade de dispersão e a resposta das espécies de pequenos mamíferos à fragmentação florestal no Planalto Atlântico Paulista / Ecological determinants of extinction risk: local abundance, niche breadth, dispersal ability and response of small mammals to forest fragmentation at the Atlantic Plateau of São Paulo
Anthropogenic disturbances, particularly habitat loss and fragmentation, are considered the main causes of the increased extinction rates observed in the last decades. Since the risk of extinction is extremely variable among species, the ecological determinants of the chance of extinction have been in the center of the debates in the ecological literature. E

7. Radio-telemetry techniques in the study of displacement of freshwater anomurans
In an ecological context, information on the movement and activity is important for understanding the requirements of habitat, resource usage patterns and the potential of interspecific interactions. The aim of this study was to examine the displacement pattern on daily activity and occupancy of substrates by Aegla manuinflata using radio-telemetry technique

8. Housing project to slums: specificities and quality parameters / Projeto de habitação em favelas: especificidades e parâmetros de qualidade
This thesis proposes a method for the development of housing units addressed to slums upgrading programs, aiming to improve the built environment in these areas. It was composed based on the housing dynamics of Sao Paulo that led to the emergence of slums, one of the main housing alternatives for low-income people in this city. The proposed method considers

9. Hormigas: relaciones especies-área en fragmentos de bosque seco tropical
We analyzed the effect of fragmentation on ant species-area and specimen frequency-area relationships in nine patches of tropical dry forest in the middle Cauca river basin in Colombia. Species richness and specimen relative frequency of ants were positively correlated with area, whereas no significant correlation was found between species richness and the d

10. Levantamento, área de vida, uso e seleção de hábitat de Falconiformes na região central do estado de São Paulo / Survey, home range, habitat use and selection of the Falconiformes in the central region of the state of São Paulo
Raptors, similarly to other animal groups, are not randomly distributed in the different habitats in the terrestrial landscape. Knowing and understanding the factors (and implications) influencing these species to chose a certain habitat are essential in ecological studies. This subject has become even more important not only because of the lack of informati

11. The ecology and behavior of thin-spined porcupine (Chaetomys subspinosus, Olfers 1818) in fragments of the Atlantic forest, Ilheus, southern Bahia / Ecologia e comportamento do ouriço-preto (Chaetomys subspinosus, Olfers 1818) em fragmentos de Mata Atlântica do município de Ilhéus, sul da Bahia
The behavioral ecology of thin-spined porcupine (Chaetomys subspinosus, Olfers 1818), threatened rodent endemic from Atlantic forest, was researched in the cacao-growing region of southern Bahia. The knowledge about basic aspects of specie natural history is still incipient. The aim of the present research was to study feeding ecology, behavior temporal orga

12. Habitat use of Tropical Screech Owl (Megascops choliba) and Burrowing Owl (Athene cunicularia) on patchez of cerrado in state of São Paulo, Brazil / Uso do hábitat da corujinha-do-mato Megascops choliba e da coruja-buraqueira Athene cunicularia (Strigiformes: Strigidae) em remanescentes de cerrado da região central do Estado de São Paulo
The Cerrado biome is the largest, richest and perhaps the most threatened tropical savannah of the world. However, most part of its natural areas has been transformed on agrosystems and pastures where basic principles of conservation werent respected. Each biological group or taxa are affected on different ways by this change. Birds of prey are particularly
