1. Comunidades de aves frugívoras e nectarívoras e disponibilidade de recursos em dois estádios sucessionais de regeneração de Mata Atlântica.
The availability of food resources in different degrees of regeneration of a forest may contribute to possible variations in species abundance and composition of bird communities. The main objective of this study is to investigate the relationship between the structure of frugivores and nectarivores bird communities and the availability of food resources - f

2. DIVERSITY, COMPOSITION AND STRUCTURE OF COMMUNITY BATS (MAMMALIA: CHIROPTERA) IN BACKWATER HABITATS CAATINGA E UPLAND FORESTS THE STATE OF SERGIPE. / DIVERSIDADE, COMPOSIÇÃO E ESTRUTURA DE COMUNIDADE DE MORCEGOS (MAMMALIA: CHIROPTERA) EM HÁBITATS DE CAATINGA E BREJO DE ALTITUDE DO ESTADO DE SERGIPE.
Bats are distributed in all Brazilian biomes. Of the 167 species known to occur in Brazil, more than 70 have been recorded in the Caatinga. Despite this diversity, the few studies available for the Caatinga are concentrated at a small number of sites, leaving considerable gaps in the data. A variety of vegetation types are found in the Caatinga. One of the m

3. Efeito do manejo de fogo sobre comunidades de aves em campos sujos no Parque Nacional das Emas, GO/MS, Cerrado Central / Effects of fire management on birds in Emas National Park, Brazil, Central Cerrado
Several studies have investigated the effects of natural fires on Cerrado birds. However, avian responses to fire management have not been examined. We compared birds found in firebreaks (fire managed areas) and in fire unmanaged grasslands, in Parque Nacional das Emas, Central Brazil. This is the first study to evaluate the effects of prescribed fire on the

4. Avifauna in brazilian urban areas, with emphasys in the Triângulo Mineiro/Alto Paranaíba cities / Avifauna em áreas urbanas brasileiras, com ênfase em cidades do Triângulo Mineiro/Alto Paranaíba
In Brazil most research with urban birds is restricted to urban parks, college campi and tree covered plazas. With the exception to the green areas of Uberlândia, very little is known about the avifauna in the cities of the Triângulo Mineiro/Alto Paranaíba region. The objectives of this thesis were to describe the avifauna of Brazilian cities by means of

5. Influencia da variação fisionomica da vegetação sobre a composição de aves frugivoras na Mata Atlantica
Due to the alarming rate of deforestation in tropical forests, a better understanding on the organization of biological communities is needed, specifically regarding the interactions between birds and plants. Although this aspect is not often included among the top priorities for biodiversity conservation, it must be considered an important of effort in the

6. Trophic and size structure of West Indian bird communities
Much discussion has occurred in recent years on whether observed patterns of structure in island bird communities are the result of competitive interactions among species or independent rates of colonization and extinction. Here two patterns of structure are presented for birds on 12 West Indian islands. Each of four major foraging guilds shows a distinct sp
