1. A new device to autonomously feed individualized mantids on extended periods of time
ABSTRACT Mantises can live for many months, are naturally voracious, and feed invariably on live prey. Many species have a propensity for cannibalism and cannot be kept together for most of their life cycle, which makes large-scale rearing typically time-consuming, thus easily becoming prohibitive. This is particularly true for early instars, because they ar

2. Biometry of neotropical invertebrates inhabiting floodplain rivers: unraveling bionomy
ABSTRACT Currently, it is widely recognized that invertebrates play key roles in neotropical floodplains and in many other environments worldwide. However, little information has been published concerning their biometry, in spite that it represents an essential tool for many different studies. Here, we provided length-mass and length-length relationships by

3. Aquisição do português como L2 por falantes de espanhol: uma experiência com o modelo de ontogenia / Acquisition of portuguese as second language (L2) by speakers of spanish: an experience with the model of ontogeny
Este estudo tem como objetivo verificar a eficácia do Modelo de Ontogenia (MAJOR, 1987), por meio da análise do processo de aquisição do português como segunda língua (L2) por falantes de espanhol no nível fonético-fonológico. Para tanto, reportamo-nos a pressupostos teóricos que antecedem o dito modelo: a Análise Contrastiva (LADO, 1957), o Model

4. Desenvolvimento floral e expressão sexual em espécies de Ficus L. (Moraceae) / Floral development and sex expression in species of Ficus L. (Moraceae)
The absence of reproductive organs in some flowers may ontogenetically arise by organ loss or suppression. Ficus L. is an interesting model for floral developmental studies, due to its diversity in sexual systems. The aim of this study was to compare the morphology of the floral development in Ficus citrifolia (monoecious), F. hispida (gynodioecious), F. rac

5. Taxonomy and biology of Haliclystus antarcticus: inferences for the evolution of Staurozoa (Cnidaria) / Taxonomia e biologia de Haliclystus antarcticus: inferências para a evolução de Staurozoa (Cnidaria)
The recent proposal of a new class of Cnidaria, Staurozoa, has contributed to a better knowledge on the group. However, data and hypotheses on evolution, taxonomy, biology, and ecology of Staurozoa are still limited, especially concerning species of the Southern Hemisphere. The aim of this study is: (1) to review characters traditionally adopted in the taxon

6. Ontogênese, função e evolução das traqueídes vasculares em Cactaceae, tendo como modelo o cacto colunar Pilosocereus aurisetus (Werdern.) Byles &G. D. Rowley / Ontogenesis, function and evolution of wide-band tracheids in Cactaceae: Ontogenesis, function and evolution of wide-band tracheids in Cactaceae: using Pilosocereus aurisetus as a model cactus.
Studies with wide-band tracheids have adressed phylogenetic and functional questions. Although these cells have been described as tracheids, with secondary cell walls thicker than 2µm, their recent register in different tissues of other families has pointed out that this definition may not be well established. The aim of the present study is to understand t

7. Ecologia das interações entre Udranomia spitzi (Lepidoptera, Hesperiidae) e formigas tendo como hospedeira Ouratea spectabilis (Ochnaceae) em um cerrado mineiro / Ecology of interactions between Udranomia spitzi (Lepidoptera, Hesperiidae) and ants on Ouratea spectabilis (Ochnaceae) in a savanna from Minas Gerais state, Brazil
Studies in multitrophic systems can serve as tools to investigate the structure and organization of ecological communities. Because it is a biome rich in multitrophic interactions, the Cerrado (tropical savanna) is a good model for the study of insect-plant interactions. Udranomia spitzi (Hesperiidae) is an endemic butterfly from Cerrado. In the immature sta

8. A concepção de homem no Behaviorismo radical e suas implicações para a tecnologia do comportamento / The conception of Man in Radical Behaviorism and its implications for Behavioral Technology
B. F. Skinner describes and explains the human behavior through the causal model of selection by consequences. According to this model, the human behavior is the product of the interaction among three levels of variability and selection (phylogeny, ontogeny and culture). According to this explanation, the cultural contingencies enable the rising and maintena

9. Caracterização do ritmo de atividade motora durante a puberdade em sagüis (Callithrix jacchus) sob condições semi-naturais
Most of ontogenetic studies on circadian timing system have been developed on infants, adults and elderly. The puberty has not been a stage of life few studied, except for researches in human adolescents, that presents phase delay in sleep-wake cycle. However, few studies have focused on the basis of this circadian change due to methodological diffic

10. 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

11. Morpho-functional characteristics of sex reversal in Synbranchidae (Teleostei: Synbranchiformes) / Perfil morfo-funcional da inversão de sexo em Synbranchidae (Teleostei: Synbranchiformes)
Teleost fishes exhibit several sexual patterns during their ontogeny, in which the gonads change into functional ovaries or testes. In distinct Orders, both gonochoristic and hermaphrodite species, simultaneous as well as sequential or consecutive, can be found. In sequential hermaphroditism (protandrous or protogynous), sex change in adult individuais invol

12. Structure of a population of Esenbeckia leiocarpa Engl. (Rutaceae) in a seasonal semidecidual forest in southeast Brazil / Estrutura de uma população de Esenbeckia leiocarpa Engl. (Rutaceae) numa floresta estacional semidecidua no Sudeste do Brasil
The present study investigated the structure of a population of Esenbeckia leiocarpa, popularly known as ?guarantã?, a canopy species, not pioneer and common in the region studied. The study was carried out in an area of 3.2 ha of seasonal semi-deciduous forest in Campinas ? SP. We randomly installed 50 plots of 10 x 10 m, in a total of 0.5 ha. In each 100
