Behavioral Evaluation of (É. Geoffroy Saint-Hilaire, 1803) in Response to Environmental Enrichment.

The environment provided for animals in captivity is less complex than its natural habitat, which generates a stressful condition. Environmental enrichment tries to meet the animals' ethological and psychological needs. This paper aims to evaluate the effect of different environmental enrichment methods on the jaguarundi (; É Geoffroy Saint-Hilaire, 1803) behavior kept in captivity at Fundação Ecológica e Zoobotânico de Brusque - SC [Brusque Ecological and Zoobotanical Foundation - SC].

Deoxyribonucleic Acid Extraction and Quantification from Human Saliva Deposited on Foods with Bitemarks.

Aim: The aim of this study is to evaluate the potential of deoxyribonucleic acid (DNA) recovery from bite marks in foods, in different collection types, from DNA quantification.

Materials And Methods: The sample consisted of 80 swabs, obtained from 20 cheese pieces, bitten by the same person, using the double-swab technique in the center and the periphery of the bite. A statistical analysis was carried out using Statistical Package for the Social Sciences (SPSS) statistical software version 20.

Cellulose biosynthesis by the beta-proteobacterium, Chromobacterium violaceum.

The Chromobacterium violaceum ATCC 12472 genome was sequenced by The Brazilian National Genome Project Consortium. Previous annotation reported the presence of cellulose biosynthesis genes in that genome. Analysis of these genes showed that, as observed in other bacteria, they are organized in two operons.
