1. Composição e sazonalidade de borboletas frugívoras no cerrado, com ênfase na relação fenológica entre Eunica bechina (Nymphalidae: Biblidinae) e sua planta hospedeira Caryocar brasiliense (Caryocaraceae) / Composition and seasonality of fruit-feeding butterflies in the cerrado savanna, with emphasis on the phenological relationship between Eunica bechina (Nymphalidae: Biblidinae) and its host plant Caryocar brasiliense (Caryocaraceae)
In many tropical environments, rainy and dry seasons alternate. The dryer season has decreased leaf availability and the nutritional quality of leaves is also low - thus it is an unfavorable period for herbivorous insects and generates seasonal oscillations in their populations. The cerrado is a neotropical seasonal biome characterized by a hot/rainy and a c

2. Ecologia Política da comida e nutrição em duas comunidades quilombolas do Vale do Ribeira (Estado de São Paulo, Brasil) / Political Ecology of food and nutrition for two Quilombola communities from Ribeira River Valley (São Paulo State, Brazil)
Quilombolas are African slave descendants. The Ribeira Valley is one of the most important areas of concentration of Quilombos in Southern Brazil. The Ribeira Quilombolas are settled in remote areas along the Ribeira River system covered by Atlantic rain forest vegetation, one of the worlds biodiversity hotspots. Since the first settlements (18th Century), t

3. Desenvolvimento ovariano e influência da cópula na maturação dos ovários de Diaphorina citri Kuwayama (Hemiptera: Psyllidae)
As many other insects with a restricted diet, the citrus psyllid Diaphorina citri Kuwayama, which vector the causing agent of the Huanglongbing, the bacteria Candidatus Liberibacter spp., is intimately associated with symbiotic microorganisms. These mutualist symbionts play a key role on their host nutritional ecology, and are vertically transmitted to the p

4. 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

5. Ecologia de Florestas Atlânticas com ocorrência do muriqui (Brachyteles spp.): diversidade, sucessão secundária e estrutura nutricional / Atlantic Forests ecology holding muriqui (Brachyteles spp.): diversity, secondary succession and nutritional structure
This study has three chapters which mainly aimed the understanding on the role of forests variables affecting distribution, abundance and range ecology of primates belonging to Brachyteles genera. The first chapter specifically aimed on characterization and comparisons of tree species diversity and secondary succession among three forests holding Brachyteles

6. Sobrepeso e obesidade: dieta, nicho alimentar e adaptabilidade em populações humanas rural e urbana de Piracicaba, SP / Overweight and obesity of rural and urban populations in Piracicaba, SP. Brazil
O presente trabalho investigou a dieta adotada por populações humanas, rural e urbana de Piracicaba, SP. Foi abordada a adaptabilidade humana, em relação à capacidade de uma população se adaptar a mudanças nutricionais, geralmente decorrentes de outras mudanças em seu ambiente. O indicador da adaptabilidade humana adotado foi o estado nutricional da

7. Papel da biodiversidade no manejo da traça-do-tomateiro Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae)
A diversificação ambiental promovida pelas espécies vegetais em agroecossistemas favorecem a estruturação de comunidades de insetos mais ricas e diversificadas que controlam a dinâmica populacional de espécies herbívoras. Dentro da abordagem agroecológica, a diversificação ambiental é um dos componentes que podem ser manejados para suprimir as po

8. Nutrição e ecologia nutricional de cervídeos brasileiros em cativeiro e no Parque Nacional das Emas - Goiás / Nutrition and nutritional ecology of brazilian cervids in captivity and in the Emas National Park - Goias
There are limited data on energy requirements of brazilian cervids. Thus, it is difficult to succeed in their management and reproduction in captivity. Knowing the energy requirements is also important to determine the necessary nutritional resources for their conservation in parks and reserves. The first objective was to study the nutritional requirements o

9. Ecologia de caiçaras : uso de recursos e dieta
This study focuses on the ecology of Caiçara populations regarding the use of natural resources and its relation with the local diet. The use of natural resources is an important feature of the Caiçara s livelihood, wbich is bistorically linked to the aquatic and terrestrial ecosystems in the Adantic Forest, through fisheries, agriculture and plant collect

10. Lifetime allocation of juvenile and adult nutritional resources to egg production in a holometabolous insect.
In holometabolous insects reproductive success is strongly determined by the nutritional resources available to the females. In addition to nutrients derived from adult feeding, resources for egg production may come from the limited reserves accumulated during the larval stages. The pattern of allocation of these larval reserves to egg production is expected

11. Ecology of Legionella pneumophila within water distribution systems.
The reservoir for hospital-acquired Legionnaires disease has been shown to be the potable water distribution system. We investigated the influence of the natural microbial population and sediment (scale and organic particulates) found in water systems as growth-promoting factors for Legionella pneumophila. Our in vitro experiments showed that: (i) water from

12. A plasmid of Rhizobium meliloti 41 encodes catabolism of two compounds from root exudate of Calystegium sepium.
Our objectives were to identify substances produced by plant roots that might act as nutritional mediators of specific plant-bacterium relationships and to delineate the bacterial genes responsible for catabolizing these substances. We discovered new compounds, which we call calystegins, that have the characteristics of nutritional mediators. They were detec
