14. Ammonia emissions in tunnel-ventilated broiler houses
Gas production in broiler houses and their emissions are closely related to the microclimate established inside the house according to air temperature, humidity, and velocity. Therefore, the internal house environment is influenced by building typology and ventilation system. The objective of the present study was to evaluate ammonia emission rates in broile

15. Surface temperature distribution in broiler houses
In the Brazilian meat production scenario broiler production is the most dynamic segment. Despite of the knowledge generated in the poultry production chain, there are still important gaps on Brazilian rearing conditions as housing is different from other countries. This research study aimed at analyzing the variation in bird skin surface as function of heat

17. Estimating mortality in laying hens as the environmental temperature increases
Layer mortality due to heat stress is an important economic loss for the producer. The aim of this study was to determine the mortality pattern of layers reared in the region of Bastos, SP, Brazil, according to external environment and bird age. Data mining technique were used based on monthly mortality records of hens in production, 135 poultry houses, from

18. Estimativa de densidade de aves utilizando amostragem por distâncias em uma área verde urbana / Estimation of bird density through distance sampling in an urban green area
O monitoramento de populações de aves em ambientes urbanos pode ser difícil devido à alta heterogeneidade, estrutura complexa e às vezes baixa visibilidade. Diferentes metodologias podem ser usadas para contagem de aves, mas, para monitoramentos, é interessante que metodologias robustas que reflitam mudanças reais em populações sejam usadas. Contage

19. Niche characterization of Sporophila spp. (Aves: Emberizidae) and its relation to microhabitat in palm swamp areas near Uberlândia, MG / Caracterização de nicho de Sporophila spp. (aves: Emberizidae) e sua relação com a estrutura de microhabitat em áreas de vereda de Uberlândia, MG
The relative importance of each environmental factor in structuring birds community seems to be variable, and each species exhibits a distinct and specific response to environmental characteristics and their changes. Some granivorous birds can perform seasonal migrations in search of good seeds. They often include the brazilian cerrado, both for breeding and

20. Contribuições para gestão urbana :corredores de vegetação para avifauna em Porto Alegre, RS
Abstract: The green tunnel is a landscape structure specific to urban arborization, formed by the joining of the canopies of trees along the roads. This dense arborization of the roads visually forms a suspended linear mass over the streets, qualifying the environment constructed by the different contributions generated by the presence of vegetation. Based u

21. Temporal organization in Pyrrhura lepida lepida / Organização temporal em Pyrrhura lepida lepida
The behaviours of many animals are organized in the rhythmic pattern as mechanism of the adaptation in a cyclical environment. The goal of this research was describe the daily distribution of the behaviors in Pyrrhura lepida lepida, to characterize your temporal organization. It was observed, individually, the behaviour of four birds that are living at the Z

22. TAXOCENOSE DAS AVES DA MICROBACIA HIDROGRÁFICA DAS NASCENTES DO RIO IBICUÍ MIRIM /RS / Taxocenosis of the birds on the micro basin of the headwaters of Ibicuí Mirim river/RS
This work was carried out in the micro basin of the headwaters of the Ibicuí Mirim river, until the Saturnino de Brito dam, and aimed to establish relationships between avifauna with different habitats in the area, using as tool the System of Geographic Information (SIG), with the purpose of evaluating the similarity of bird species in an environment with t

23. Filogeografia, morfometria e distribuição geográfica potencial de populações de Rhodnius neglectus (Hemiptera, Reduviidae) no Brasil
Sylvatic triatomines of the genus Rhodnius commonly fly into houses in Latin America, maintaining the risk of Chagas disease transmission. In this thesis, phylogeographical, morphological and potential geographical distribution analyses of Rhodnius populations in central Brazil were carried out, focusing in R. neglectus, the major species found in palm trees

24. Correlations among behavior, performance and environment in broiler breeders using multivariate analysis
Animal welfare issues have received much attention not only to supply farmed animal requirements, but also to ethical and cultural public concerns. Daily collected information, as well as the systematic follow-up of production stages, produces important statistical data for production assessment and control, as well as for improvement possibilities. In this
