1. Effect of immunocastration on sex glands of male Mangulica (Swallow-bellied Mangalitsa) pigs
ABSTRACT The objective of this research was to study the effect of immunocastration on the morphometric characteristics of sex glands in male Swallow-bellied Mangalitsa pigs. The study included 24 animals (13 entire and 11 immunocastrated males). The research focused on the following traits: age at slaughter (days), live weight at slaughter (kg), growth rate

3. Composition and ecology of a snake assemblage in an upland forest from Central Amazonia
Abstract: Most species of Amazonian snakes have wide geographic distributions. However, local environmental factors influence the formation of assemblages in different localities. In this study, we investigated the composition of the assemblage and the effect of environmental variables on the distribution of the species inhabiting an upland forest in the Exp

4. The eco-epidemiology of Triatoma infestans in the temperate Monte Desert ecoregion of mid-western Argentina
BACKGROUND The eco-epidemiological status of Chagas disease in the Monte Desert ecoregion of western Argentina is largely unknown. We investigated the environmental and socio-demographic determinants of house infestation with Triatoma infestans, bug abundance, vector infection with Trypanosoma cruzi and host-feeding sources in a well-defined rural area of

6. Estimation of dry mass of caddisflies Phylloicus elektoros (Trichoptera: Calamoceratidae) in a Central Amazon stream
Aquatic invertebrate biomass estimations are often important in ecological and biological studies. Biomass may be determined by regression models between body and case dimensions and dry mass. Using linear, exponential and power regressions we analyzed the relationship between body and case dimensions and the biomass of Phylloicus elektoros Prather, 2003. Fu

7. Caracterização da comunidade de mamíferos de médio e grande porte em paisagem agrícola fragmentada / Characterization of the mid and large bodied mammal community in a fragmented agricultural landscape
Agricultural expansion is a major cause of habitat fragmentation, leading to a reduction and isolation of natural areas. It is therefore important to understand the role of agricultural landscape structure and dynamics in maintaining local biodiversity. We aimed to describe how the structure and dynamics of an agricultural landscape influenced the community

8. Effects of variety, cropping system and soil inoculation with Aspergillus flavus on aflatoxin levels during storage of maize
The effects of soil inoculation with A. flavus, variety and cropping system on the level of aflatoxin in stored maize were investigated under crop storage conditions in Benin. The experiment was organized in a factorial scheme (two varieties x two cropping system x with or without A. flavus soil inoculation) with eight treatments carried out in a completely

9. AVALIAÇÃO DO RUÍDO DE TRÁFEGO VEICULAR EM ÁREA CENTRAL DE CHAPECÓ SC / EVALUATION OF VEHICULAR TRAFFIC NOISE IN CENTRAL ZONE CHAPECÓ SC
The development of cities and population growth have led, among other urban problems, the increase in sound pressure levels of environmental noise. With the overcrowding of cities, the roads start to host large flows of vehicles, among other sound sources. These factors, coupled with the layout and massing of buildings, make the road a polluter responsible f

10. Contribuição da modelagem espacial para o estudo de palmeiras: a Euterpe edulis Mart. na mata Atlântica e a família Arecaceae no Brasil / Contribution of spatial modeling to palm research: The Euterpe edulis Mart. in Atlantic forest and Arecaceae family in Brazil
Este trabalho apresenta duas formas de estudar a distribuição espacial de palmeiras considerando diferentes escalas. Em escala local, a distribuição da densidade de \textit {Euterpe edulis} Mart. (juçara) foi estudada ao longo do gradiente altitudinal do Parque Estadual Serra do Mar - PESM. Foram utilizados os dados de \textit {E. edulis} adquiridos em

11. Modelos de regressão com e sem fração de cura para dados bivariados em análise de sobrevivência / Models with and without fraction of cure for bivariate data in survival analysis
Neste trabalho são reunidos diferentes modelos e técnicas para representar situações experimentais ou observacionais de análise de sobrevivência. Para modelar respostas bivariadas e covariáveis foi proposto o modelo de regressão Kumaraswamy-Weibull bivariado. A presen»ca de indivíduos curados foi considerada sob duas diferentes abordagens, originan

This research aims to assess the fish biodiversity of the streams of the Tocantins and Araguaia basin and test the relative influence of local and regional processes in determining local species richness by examining the relationship between local species richness and regional species richness. For this purpose were sampled 18 streams in the basin of the Ara
