1. Exploring the Insecticide and Acaricide Potential of Development Regulators obtained from Restinga vegetation from Brazil
Abstract: As a part of our continuing search for insect and arthropod development regulators from Brazilian restinga vegetation of the Rio de Janeiro State, crude extracts, purified fractions and essential oils were submitted to screening tests seeking for biological activities on the development of the insects Rhodnius prolixus, Dysdercus peruvianus, Oncope

2. The influence of environmental variables in the reproductive performance of Macrobrachium amazonicum (Heller, 1862) (Caridea: Palaemonidae) females in a continental population
ABSTRACT Macrobrachium amazonicum is a commercially important freshwater prawn with a high degree of reproductive plasticity. The species is classified into two groups: coastal populations, with larger individuals exhibiting high fecundity and needing brackish water for larval development; and continental populations, with smaller specimens exhibiting low fe

3. Tadpoles of the High-Andean Hyloxalus subpunctatus (Anura: Dendrobatidae) with description of larval variation and species distinction by larval morphology
This study redescribes the tadpoles of Hyloxalus subpunctatus (Anura: Dendrobatidae) based on larvae from the type locality and over most of its geographic range, including all stages of ontogenetic development. I describe tadpoles in the three developmental phases: (1) back-riding tadpoles, (2) free-swimming tadpoles, (3) froglets or individuals in metamorp

4. Zonas de promiscuidade: trottoir do desejo sexual
The subject of this study is a moral web (where desire pulses for new arrangements and combinations) that consists of different elements mixed without order or criterion in a promiscuous way. In order to undo the sexuality devices knots, this study demonstrates that sexual desire is a dimension that cannot be reduced to the logic of representation. Rather it

5. Relationship virtual communities as a potential agent of emancipation / Comunidades de relacionamento virtual como agentes potencializadores de emancipação
A presente pesquisa que trabalha com a perspectiva da Psicologia Social pretende compreender os processos envolvendo a metamorfose identitária (CIAMPA, 1987, 1995) de pessoas que utilizam as comunidades de relacionamento virtual como um meio importante para suas construções sociais e identidade. A intensificação do virtual na contemporaneidade é uma qu

6. Memória se faz na História: Um Estudo da Identidade de Metodistas Militantes Sociais Orientados pela Teologia da Libertação / Memory is made upon History: a Case of Identity of Socially Militant Methodists Oriented by Liberation Theology
This research had as its main focus the religious experience of activists who define themselves as Methodist protestants and that became involved in social movements oriented by Liberation Theology, with the objective of understanding the formation and transformation process of human identity as a metamorphosis that searches for emancipation. In the analysis

8. Metamorphosis of a Scleractinian Coral in Response to Microbial Biofilms
Microorganisms have been reported to induce settlement and metamorphosis in a wide range of marine invertebrate species. However, the primary cue reported for metamorphosis of coral larvae is calcareous coralline algae (CCA). Herein we report the community structure of developing coral reef biofilms and the potential role they play in triggering the metamorp

9. Potential role for a FTZ-F1 steroid receptor superfamily member in the control of Drosophila metamorphosis.
FTZ-F1, a member of the steroid receptor superfamily, has been implicated in the activation of the homeobox segmentation gene fushi tarazu early in Drosophila embryogenesis. We have cloned a developmental isoform of FTZ-F1 and found that it is expressed as a product of the previously identified, midprepupal chromosome puff at 75CD. The 75CD puff occurs in th

10. Xenopus sonic hedgehog as a potential morphogen during embryogenesis and thyroid hormone-dependent metamorphosis.
The hedgehog family of proteins have been implicated as important signaling molecules in establishing cell positional information and tissue patterning. Here we present the cloning and characterization of a hedgehog homologue from Xenopus laevis similar to the sonic class of vertebrate hedgehog genes. We isolated Xenopus hedgehog (Xhh) from a subtractive hyb

11. Spontaneous heterosis in larval life-history traits of hemiclonal frog hybrids
European water frog hybrids Rana esculenta (Rana ridibunda × Rana lessonae) reproduce hemiclonally, transmitting only their ridibunda genome to gametes. We compared fitness-related larval life-history traits of natural R. esculenta from Poland with those of the two sympatric parental species and of newly generated F1 hybrids. Compared with either parental s

12. Differential Regulation of Cell Type-specific Apoptosis by Stromelysin-3: A POTENTIAL MECHANISM VIA THE CLEAVAGE OF THE LAMININ RECEPTOR DURING TAIL RESORPTION IN XENOPUS LAEVIS*
Matrix metalloproteinases (MMPs) have been extensively studied because of their functional attributes in development and diseases. However, relatively few in vivo functional studies have been reported on the roles of MMPs in postembryonic organ development. Amphibian metamorphosis is a unique model for studying MMP function during vertebrate development beca
