1. Bone, fat, and muscle interactions in health and disease
Abstract Energy metabolism is a point of integration among the various organs and tissues of the human body, not only in terms of consumption of energy substrates but also because it concentrates a wide interconnected network controlled by endocrine factors. Thus, not only do tissues consume substrates, but they also participate in modulating energy metaboli

2. Trade-off in plant-ant interactions: seasonal variations
Resumo Este trabalho avaliou o efeito da sazonalidade sobre a interação planta-formiga em uma Floresta Tropical Sazonal Seca, utilizando como modelo ecológico a espécie Ipomoea carnea subs. fistulosa (Convolvulaceae). Realizamos coleta sistemática de formigas, herbívoros e folhas em plantas marcadas, avaliamos a eficiência de captura de herbívoros pe

3. Trophic dynamics (Dissolved Inorganic Nitrogen-DIN and Dissolved Inorganic Phosphorus-DIP) in tropical urban estuarine systems during periods of high and low river discharge rates
Abstract: This paper focused on the use of the biogeochemical LOICZ (Land Ocean Interactions in the Coastal Zone) to investigate the dynamics of DIN and DIP nutrients among three highly urbanized tropical estuaries (Barra das Jangadas (BJ), Recife (RE) and Timbó (TB)), located in the northeastern region of Brazil. The input data were obtained through in sit

4. Assessment of the predatory capacity on mosquito larvae of Jenynsia multidentata (Anablepidae) in presence of vegetation under laboratory conditions
ABSTRACT Larvivorous fish have been studied as potential biocontrol agents of mosquito larvae and pupae through their trophic interactions. The use of native fish for mosquito control may have benefits for both aquatic biodiversity and human health. Evaluating the effect of vegetation on the predatory efficacy is fundamental to determine if this species ca

5. Food web and ecological models used to assess aquatic ecosystems submitted to aquaculture activities
RESUMO: Ecossistemas aquáticos continentais desempenham papel fundamental no desenvolvimento econômico e social, entretanto, são vulneráveis à degradação ambiental devido às diversas pressões a que estão submetidos. Entre as principais atividades antrópicas a interferir nestes ambientes, podemos destacar a aquicultura. A modelagem matemática de

6. Trophic ecology of citrus pests based on stable isotope analysis
ABSTRACT: Macrodactylus pumilio Burm. (Coleoptera: Scarabeidae) and Naupactus cervinus (Boh.) (Coleoptera: Curculionidae) are considered primary pests in citrus crops in Brazil, causing damage to plants and decreasing productivity. However, few studies investigate the ecology of these insects. In this context, the use of stable isotopes analysis (SIA) emerge

7. Effects of glutamine alone or in combination with zinc and vitamin A on growth, intestinal barrier function, stress and satiety-related hormones in Brazilian shantytown children
OBJECTIVE: To determine the impact of supplemental zinc, vitamin A, and glutamine alone or in combination on growth, intestinal barrier function, stress and satiety-related hormones among Brazilian shantytown children with low median height-for-age z-scores. METHODS: A randomized, double-blind, placebo-controlled trial was conducted in children aged two mo

8. Introducing the term 'Biocontrol Plants' for integrated pest management
Studies of interactions between crops, additional plants, pests and beneficial organisms already exist as well as studies of natural enemy preference, dispersal, and abundance. However, these studies focus on tri-trophic interactions from an "arthropod" point of view. We think that in order to optimize crop protection methods we need to understand the effect

9. Influência da agregação larval na história de vida de Ascia monuste orseis (Godart, 1819) (Lepidoptera, Pieridae) / Influence of larval aggregation on life-history traits of Ascia monuste orseis (Godart, 1819) (Lepidoptera, Pieridae)
In insects, the gregarious habit has been shown to improve foraging and defense against predation to both larval and adult stages. Egg clusters could also be beneficial through increased larval hatching. In this study, we tested the hypothesis that egg clusters and larval aggregations of the neotropical butterfly Ascia monuste orseis (Godart, 1819) (Pieridae

10. Interações tróficas de peixes marinhos no Estado de São Paulo: banco de dados e comparações espaço-temporais / Trophic interactions of marine fish in the State of São Paulo: database and spatial-temporal comparisons
The marine ecosystems of São Paulo State are under intense anthropic pressure. Considering that trophic studies of fishes are essential to the management of ecosystems and fisheries, a fish stomach content database was built in order to summarize the available data in the region. Primary (unpublished) and secondary (published) data were inserted, representi

11. Interação trófica entre Podisus nigrispinus e Supputius cincticeps (Heteroptera: Pentatomidae) / Trophic interaction between Podisus nigrispinus and Supputius cincticeps (Heteroptera: Pentatomidae)
Prey may be more or less consumed by control biologic agents and presents three kinds of interspecific interactions, (1) synergism, increase of mortality of prey comparing to each natural enemy independently, when the foraging of one species facilitates the capture of pest by another natural enemies. (2) Total mortality of the pest to natural enemies equals

12. Ecologia trófica e ecomorfologia da ictiofauna de igarapés maranhenses
The trophic ecology is one of the most important aspects to understand the role of a species in the community and in the ecosystem functioning. Studies regarding the feeding of fishes coupled to the ecomorphology of a species become important tools in understanding their ecological role and position in the environment. The present study aimed to analyze the
