1. 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

2. Sexual behavior of the digger wasp Sphex ingens Smith (Hymenoptera, Sphecidae)
A species' mating system depends on its spatial distribution and temporal availability of mating opportunities, as well as on the resources that create these opportunities. In addition, for many species, courtship is driven by specific behaviors that precede and follow copulation. Although Sphex ingens is a taxonomically well known species of digger wasp, it

3. Padrões bioenergéticos das aranhas de teia: considerações sobre a unidade e a diversidade do fenômeno / Patterns of bioenergetic of web spiders: considerations about the unity and diversity of the phenomenon
The physiological mechanisms are often applied to explain important evolutionary adaptations (e.g. endothermy) and ecology (e.g. physiological limitations to occupy a particular microhabitat) of vertebrates. Despite the fact that it improves vertebrates ecological and evolutionary hypotheses with possible processes and mechanisms, it is scarcely used to unde

4. Behavioral evidence for cone-based ultraviolet vision in divergent bat species and implications for its evolution
We investigated the reactions of four bat species from four different lineages to UV light: Hipposideros armiger (Hodgson, 1835) and Scotophilus kuhlii Leach, 1821, which use constant frequency (CF) or frequency modulation (FM) echolocation, respectively; and Rousettus leschenaultii (Desmarest, 1820) and Cynopterus sphinx (Vahl, 1797), cave and tree-roosting

5. Ecologia comportamental e diversidade em um sistema hospedeiro-parasitóide : vespas parasitóides de Schismatodiplosis lantanae Rübsaamen, 1916 (Cecidomyiidae) em Lantana camara L. (Verbenaceae)
We investigated the ecology of parasitoid wasps attacking Schismatodiplosis lantanae Rübsaamen, 1916 (Cecidomyiidae) galls on leaves of Lantana camara L. (Verbenaceae). The first article discusses the behavioral ecology of the parasitoid wasp Torymus sp. (Torymidae, Hymenoptera), reporting how their females defend oviposition resources on the hosts, changin

6. Projeto raia de fogo: aspectos populacionais da raia de fogo (Dasyatis marianae Gomes, Rosa &Gadig, 2000) e pesca de elasmobrânquios no complexo recifal do Parracho de Maracajaú
The species Dasyatis marianae inhabits coastal areas associated with coral reefs, considered endemic to the northeast of Brazil, occurring from the State of Maranhão to the south of Bahia. Specimens of this species are commonly sighted by divers and fishermen in the area of Maracajaú reefs, a complex reef that is part of the Environmental Protection Area o

7. Behavioral ecology of Heteragrion consors Hagen (Odonata, Megapodagrionidae): a shade-seek Atlantic forest damselfly
Ecologia comportamental de Heteragrion consors Hagen (Odonata: Megapodagrionidae): uma libélula de áreas sombreadas da Floresta Atlântica. A intensidade de seleção inter e intra-sexual deve afetar características comportamentais dos machos como fidelidade a territórios e agressividade possibilitando a existência de diferentes estratégias.

Neste trabalho tivemos como objetivo caracterizar a dieta, uso do habitat e padrões comportamentais de Astyanax taeniatus da bacia do Rio Mato Grosso, que encontra-se na porção leste do Estado do Rio de Janeiro (22 52 S; 42 40 W e 22 53 S; 42 34 W). Para a análise da dieta, os exemplares foram coletados bimestralmente entre março de 2006 e janeiro de 20

9. Construct validity of behavioral models of anxiety: where experimental psychopathology meets ecology and evolution
In experimental psychopathology, construct validity is usually enhanced by addressing theories from other fields in its nomological network. In the field of anxiety research, this construct is related to antipredator behavior, conserved across phylogeny in its functions and neural basis, but not necessarily on its topography. Even though the relations betwee

11. Ecology, behavior and natural history of the harvester ant Pogonomyrmex naegelii (Formicidae, Myrmicinae) in cerrado vegetation: activity schedule, diet, home range, nest structure and demography / Ecologia, comportamento e história natural da formiga ceifeira Pogonomyrmex naegelii (Formicidae, Myrmicinae) em cerrado : ritmo biológico, dieta, área de vida, estrutura e demografia dos ninhos
Pogonomyrmex naegelii belongs to the group known as harvester ants, which collects and stores seeds in underground chambers for later consumption. These ants can be found in both warm temperate and tropical regions around the world, especially in areas of semiarid to arid vegetation, although they may also be found in moist habitats.
