1. Anthelmintic activity of plant aqueous extracts against Panagrellus redivivus in vitro
RESUMO O controle de fitonematoides é muito difícil e requer uma combinação de técnicas para ter sucesso. O controle alternativo via extrato vegetal pode resultar na descoberta de substâncias nematicidas. Esta pesquisa objetivou avaliar o efeito de 33 plantas submetidas à extração aquosa contra Panagrellus redivivus in vitro. As concentrações fora

2. Lizard assemblages on sandy coastal plains in southeastern Brazil: An analysis of occurrence and composition, and the role of habitat structure
Abstract Data on the structure of lizard communities in the different biomes and ecosystems of Brazil are still limited. In this study, we related the species richness, abundance and the spatial occurrence of lizards to the structure of the vegetation found on the coast of the state of Espírito Santo, southeastern Brazil, to determine whether habitat influe

3. Ciclagem de matéria nos ecossistemas oligotróficos de restinga e a importância da espécie chave Clusia hilariana
Resumo: Restingas são terraços arenosos dispostos ao longo da costa brasileira. Dois tipos de vegetação são muito comuns nas restingas do sudeste brasileiro, formações Clusia e formação florestal sazonalmente seca. A produção de serapilheira e o turnover de nutrientes (C e N) foram estudados comparativamente na formação florestal e na formação

5. Laboratory evaluation of Clusia fluminensis extracts and their isolated compounds against Dysdercus peruvianus and Oncopeltus fasciatus
ABSTRACT The effects of the hexanic extracts of the fruits and flowers of Clusia fluminensis Planch. & Triana, Clusiaceae, as well as their main constituents, the triterpene lanosterol and the benzophenone clusianone, were evaluated on hemipterans Dysdercus peruvianus and Oncopeltus fasciatus. The topical treatments of insects with the hexanic extracts signi

8. Phytochemical study and evaluation of cytotoxic and genotoxic properties of extracts from Clusia latipes leaves
Abstract Some species of the Clusia genus have been shown to have important biomedical properties, including the ability to inhibit tumor growth in vitro and the usefulness for skin care. In this study, we examined the cytotoxic effect of hexane, ethyl acetate and methanol extracts from Clusia latipes Planch. & Triana, Clusiaceae, leaves on survival of human

9. Dinâmica da regeneração natural em uma floresta baixa de restinga degradada
Este estudo teve como objetivo caracterizar a composição da chuva e banco de sementes em uma floresta baixa de restinga degradada, a fim de verificar o aporte e estabelecimento dos diásporos na área e a contribuição dos remanescentes próximos para a regeneração natural. Num trecho degradado em Ilha Comprida, dez coletas mensais (1 m2 cada) para a ch

10. Characterization saprobic fungi on leaf litter of two species of trees in the Atlantic Forest, Brazil
Abstract We investigated the composition and structure of fungal communities associated with leaf litter generated by Clusia nemorosa and Vismia guianensis that belong to phylogenetically-related botanical families and exist together in a remnant of the Atlantic Forest in Bahia, Brazil. Samplings were conducted during wet (June 2011) and dry (January 2013) s

11. Biocontrol evaluation of extracts and a major component, clusianone, from Clusia fluminensis Planch. & Triana against Aedes aegypti
Studies evaluated the effects of hexanic extracts from the fruits and flowers of Clusia fluminensis and the main component of the flower extract, a purified benzophenone (clusianone), against Aedes aegypti. The treatment of larvae with the crude fruit or flower extracts from C. fluminensis did not affect the survival of Ae. aegypti (50 mg/L), however, the fl

12. Bryophyte and pteridophyte spores and other palynomorphs in quaternary marine sediments from Campos Basin, southeastern Brazil: Core BU-91-GL-05
This paper presents morphological descriptions and ecological data of cryptogam spores and other non-pollen palynomorphs from Quaternary sediments of Campos Basin, Rio de Janeiro, SE Brazil. The ages were derived from biostratigraphy of planktonic foraminifers and two radiocarbon dates, and suggest that sediment deposition started in the last 140,000 years B
