13. Feeding ecology of stream-dwelling Characidae (Osteichthyes: Characiformes) from the upper Tocantins River, Brazil
In this contribution we studied the trophic ecology of four Characidae species from the Cavalo Stream, upper Tocantins River, considering diet overlap and trophic niche breadth. The diet of the four species was composed of adult and immature insects, both autochthonous and allochthonous in origin. Autochthonous items dominated the diet of Moenkhausia dichrou

14. Habitat and food selection by herbivorous amphipods associated with macroalgal beds on the southeast coast of Brazil
The factors that influence the selection of marine macrophytes by meso-herbivores are complex, and may include the nutritional quality of algae, the value of the habitat as a shelter, and the availability of algae in the environment. Here we investigated the existence of differential use of Sargassum filipendula C. Agardh, 1824 (Phaeophyta) and Galaxaura stu

15. Stage preference and functional response of Rhynocoris longifrons (Stål) (Hemiptera: Reduviidae) on three hemipteran cotton pests
In this work, the stage preference and functional response of the indigenous reduviid bug Rhynocoris longifrons feeding on five different densities of the cotton aphid Aphis gossypii, Phenacoccus solenopsis, and Dysdercus cingulatus was examined in Petri dish arenas containing cotton leaves under laboratory conditions. The reduviid predator exhibited a Type

16. Trophic ecology and microhabitat utilization by the Bufo gargarizans, Rana guentheri, and Rana limnocharis in southwestern China
We studied the trophic ecology and microhabitat use of the Asiatic toad, Bufo gargarizans Cantor, 1842; Guentheri frog, Rana guentheri (Boulenger, 1882); and the Ricefield frog, Rana limnocharis (Boie, 1834). These three species are common around Nanchong City, in southwestern China, where they live in the same habitat before hibernation. The main objective

17. Investigação das alterações do consumo de alimento palatável induzidas por trauma precoce em ratas fêmeas
Introduction: Chronic stress in adulthood increases anxiety and prones the individuals to use palatable foods as ¿comfort foods¿, which seems to be mediated by an altered functioning of the hypothalamus-pituitary-adrenal axis (HPA). We aimed at verifying if early life stress also affects anxiety, feeding behavior and stress responses in adult female rats.

18. Feeding preference of adult females of ribbonfish Trichiurus lepturus through prey proximate-composition and caloric values
No presente estudo foram analisadas a composição centesimal e o valor calórico das presas preferenciais consumidas pelo peixe-espada, Trichiurus lepturus L. 1758 (fêmeas adultas), que se distribuem na plataforma continental interna do norte do estado do Rio de Janeiro, sudeste do Brasil (~ 22ºS). O objetivo foi avaliar o potencial da abordagem nutricion

19. RelaÃÃes ecolÃgicas entre Melampus coffeus (Gastropoda: Pulmonata) e a serapilheira no mÃdio estuÃrio do rio Pacoti, Cearà / Ecological relations between Melampus coffeus (Gastropoda: Pulmonata) and the leaflitter in the middle estuary of Pacoti river, CearÃ
The litter is essential for the nutrients and organic matter cycles in forests ecosystems. These vegetal detritus are a food source to many groups of animals that act directly on the litter decomposition. Litter also seems to provide microhabitats and works as a shelter for many individuals of the mangrove fauna. The gastropod Melampus coffeus (Linnaeus, 175

20. Behavioral evidence of an ectoparasitic interaction between Triatoma pseudomaculata Corrêa e Espínola (Heteroptera: Reduviidae) and Periplaneta americana (L.) (Blattodea: Blattidae)
The present work tested whether Triatoma pseudomaculata Corrêa & Espínola shows behavioral traits indicating that it is capable of feeding on arthropods. We consistently observed nymphs extending their proboscis in the direction of cockroaches and attempting to bite. Insects presented a preference for biting specific cockroach body parts. Our results sugge

21. 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

22. Coordinated feeding tactics of the Guiana dolphin, Sotalia guianensis (Cetacea: Delphinidae), in Ilha Grande Bay, Rio de Janeiro, Brazil
Differences in distribution, prey species, season and social learning opportunities influence the feeding tactics used by marine mammals. Here, we analyze the coordinated feeding behavior of the Guiana dolphin, Sotalia guianensis (Van Bénéden, 1864, Delphinidae) and its relation to seasonality and the presence of calves. In a total of 201 feeding bouts, we

23. Oviposition and Feeding Preferences of the Bollworm on Cotton.
Oviposition and feeding preferences of the bollworm, Heliothis zea (Boddie) on cotton, Gossypium hirsutum L., cultivar ´Tamcot CAMD-E´. were studied. A highly significant number of eggs on termnal and leaves indicated clearly that bollworm moths exibit a high degree of preference for egg placement on these parts. Feeding sites for bollworm larvae were quit
