1. Distant populations of a Xanthosoma (Araceae) species have different floral scents but the same cyclocephaline beetle pollinators
ABSTRACT We report on the reproductive biology, pollinators, and thermogenesis of the widely distributed Araceae species, Xanthosoma striatipes. We analyzed the floral scent in one population and compared it to a previous study. Xanthosoma striatipes was studied at three sites in Brazil, São Paulo, Minas Gerais and Maranhão. The results showed constancy of

3. Bees biodiversity, forage behavior and fruit production in gherkin crop (Cucumis anguria L.)
ABSTRACT. The objectives were to evaluate the biodiversity of bees, forage behavior and their effect on fruit production in the gherkin crop (Cucumis anguria L.) in the campus of the University Center Moura Lacerda in two years. The frequency and type of collection of the insects in the flowers was observed by counting from 8:00 a.m. to 5:00 p.m., in the fir

5. Trajetória e mutações do utilitarismo jurídico-penal: um ensaio de história das ideias
Resumo Este texto aborda a biografia do utilitarismo jurídico-penal moderno focando três importantes momentos de seu desenvolvimento: o utilitarismo ilustrado (Bentham e Beccaria), o utilitarismo reformado (Ferrajoli) e a crise do utilitarismo penal, denunciada pela criminologia crítica, em suas vertentes minimalistas e abolicionistas. O instrumental teó

7. Leaf-litter Entomofauna as a Parameter to Evaluate Areas Under Ecological Restoration
ABSTRACT The aim of this study was to characterize the leaf-litter entomofauna in degraded areas under restoration process with different restoration techniques, using the native forest as a reference and ecological indexes as parameters to select bioindicator groups. The study was conducted at “Serra do Itajaí” National Park (PNSI). The survey was cond

9. Comparison of beat cloth and entomological net methods for determining faunistic indices of soybean in Rio Grande do Sul, Brazil
ABSTRACT Estimates of diversity indices provide information on distribution, richness and abundance of species within a community. The aim of the current study was to estimate faunistic indices (richness, constancy, dominance and abundance) of the species collected by beat cloth and entomological net sampling methods in different soybean crops and to determi

11. Diversity of myxomycetes in an environmentally protected area of Atlantic Forest in northeastern Brazil
The present study was carried out on three trails, each presenting a different degree of disturbance, within the Pau-Ferro Forest Environmentally Protected Area, a 600 ha area of highland forest located in the municipality of Areia (06°58'12"S; 35°42'15"W; elevation, 400-600 m), in the state of Paraíba, Brazil. In 2005, we analyzed the species richness, a

12. Vertical structure of an assemblage of bats (Mammalia: Chiroptera) in a fragment of Atlantic Forest in Southern Brazil
Few studies have focused the vertical structure of bat assemblages, and how it influences community composition. The goal of this study was to analyze the vertical structure of an assemblage of bats in a forest fragment in southern Brazil. Bats were sampled using mist-nets placed at three heights (understory, below-canopy, and canopy). Forest strata were com
