1. Desnutrição perinatal e o controle hipotalâmico do comportamento alimentar e do metabolismo do músculo esquelético
A deficiência de nutrientes durante os períodos críticos do desenvolvimento tem sido associada com maior risco para desenvolver obesidade e diabetes Mellitus na vida adulta. Um dos mecanismos propostos refere-se à regulação do comportamento alimentar e às alterações do metabolismo energético do músculo esquelético. Recentemente, tem sido proposta

2. What can we learn from confusing Olivella columellaris and O. semistriata (Olivellidae, Gastropoda), two key species in panamic sandy beach ecosystems?
Olivella columellaris (Sowerby 1825) and O. semistriata (Gray 1839) are suspension-feeding, swash-surfing snails on tropical sandy beaches of the east Pacific. While they often are the numerically dominant macrofaunal element in their habitats, their biology is poorly understood; the two species actually have been confused in all of the few publications that

3. Ecologia trófica da ictiofauna e simpatria de espécies congenéricas no córrego da Lapa, bacia do Alto Paraná, estado de São Paulo, Brasil
Streams and rivers are loctic environments characterized for a strong and unidirectional water flow. These environments in general have the light incidence partial or totally obstructed by the canopy of the riparian vegetation showing a high dependence of allocthonus organic inputs. The stream fishes are usually small sized, with reproductive strategies adap

4. Influence of previous experience on the preference, food utilization and performance of Ascia monuste orseis wild larvae (Godart) (Lepidoptera: Pieridae) for three different hosts
The exhaustion of food resources which occurs during the ontogenetic growth of Ascia monuste orseis (Godart) results in the dispersion of older larvae to nearby plants in order to complete their development, which might expose these animals to the nutritional variation of the hosts found. This study aimed to verify whether the food ingested in the beginning

5. Ontogenetic predation capacity of Macrobrachium borellii (Caridea: Palaemonidae) on prey from littoral-benthic communities
Macrobrachium borellii is an abundant prawn of the Paraná River floodplain. Newly hatched juveniles have the general characteristics of adults, and they are proposed to have the same feeding habits. Its natural diet is composed mainly of animals' items rather than vegetals, of which dipteran larvae and oligochaetes are positively selected. However, the osci

6. Alimentação de Liposarcus anisitsi e Potamorhina squamoralevis, peixes abundantes na Baía Tuiuiú, Pantanal, Mato Grosso do Sul, Brasil.
Os grandes sistemas fluviais da América do Sul abrigam uma grande diversidade de espécies de peixes, que obtém o alimento nas mais diversas fontes. Este trabalho visou identificar e analisar a composição da dieta de Liposarcus anisitsi e Potamorhina squamoralevis, espécies abundantes na baía Tuiuiú, Pantanal, Mato Grosso do Sul. Foram realizadas cole

7. Predatory behavior of the land flatworm Notogynaphallia abundans (Platyhelminthes: Tricladida)
Land flatworms are carnivorous, mainly predators. However, knowledge on their predatory behavior and prey preference is very scarce. This paucity of data is a limiting factor in the study of their biology and organismal ecology, resulting in a very difficult task to breed them in the laboratory for prolonged periods if prey preference and predation frequency

8. Variações em caracteres morfológicos e ecológicos em populações de Bothrops jararaca (Serpentes: Viperidae) no estado de São Paulo / Variations in morphological and ecological characters of Bothrops jararaca populations (Serpentes: Viperidae) in São Paulo State
Widely distributed snakes exposed to different conditions of temperature and precipitation throughout their distributions may present geographic variation in morphological and ecological characters (e.g. diet and reproduction). In this study, I investigate whether Bothrops jararaca populations from coastal and adjacent mid-elevation sites of the Serra do Mar

9. Culinária típica e identidade regional: a expressão dos processos de construção, reproduçãoe reivenção da mineiridade em livros e restaurantes de comida mineira
M.A. dissertation in Social History of the Culture, that tried to understand the plasticity of the regional identity of Minas Gerais, starting from the following sources: books and restaurants related to the regional typical cookery. The work was divided in three chapters. First, the focus was the institution and consolidation of the history of feeding as a

10. Central localization of plasticity involved in appetitive conditioning in Lymnaea
Learning to associate a conditioned (CS) and unconditioned stimulus (US) results in changes in the processing of CS information. Here, we address directly the question whether chemical appetitive conditioning of Lymnaea feeding behavior involves changes in the peripheral and/or central processing of the CS by using extracellular recording techniques to monit

11. Dynamical basis of intentions and expectations in a simple neuronal network
Selection of behavioral responses to external stimuli is strongly influenced by internal states, such as intentions and expectations. These internal states are often attributed to higher-order brain functions. Yet here we show that even in the simple feeding network of Aplysia, external stimuli do not directly specify which motor output is expressed; instead

12. The role of n-3 polyunsaturated fatty acids in brain: Modulation of rat brain gene expression by dietary n-3 fatty acids
Rats were fed either a high linolenic acid (perilla oil) or high eicosapentaenoic + docosahexaenoic acid (fish oil) diet (8%), and the fatty acid and molecular species composition of ethanolamine phosphoglycerides was determined. Gene expression pattern resulting from the feeding of n-3 fatty acids also was studied. Perilla oil feeding, in contrast to fish o
