| Many methods of age determination have been used to date. However, most of them require laboratory procedures which are, in general, not available for wildlife managers in the field. In this paper we attempt to standardize the age categories for six mammal species through the analysis of dental wear, dental eruption and body mass. We analyzed 632 skulls, including Mazama nemorivaga (brown brocket deer), Mazama americana (red brocket deer), Tayassu pecari (white-lipped peccary), Pecari tajacu (collared peccary), Cuniculus paca (paca) and Dasyprocta leporina (agouti). Using biological and morphological criteria we define four age categories: young, sub adult, adult and senescent adult. Scores and variables of molar cusp wear and eruption were defined for... |

| Aspectos macroscópicos e morfométricos dos testículos em catetos e queixadas. Este trabalho objetiva fornecer dados macroscópicos e morfométricos dos testículos dos catetos e queixadas. O material utilizado consistiu de catetos e queixadas oriundos da Fazenda Devaneio Pró-Fauna, Iguape, SP (Reg.1/3593/08480). Em 33 queixadas e 20 catetos, após o abate, os testículos foram colhidos e tomados dados morfométricos como: comprimento, largura e espessura (com o auxílio de um paquímetro). Os testículos são ovalados, localizados na região pélvica, inclinados dorso-caudalmente e possuem posição intermediária. O mediastino testicular esta no centro do testículo, ligeiramente desviado para a margem epididimária deste, e termina na extremidade capitata. Os queixadas... |

| Wild animals have been used as bioindicators in situations in which the environment was exposed to chemical agents. In general, chemical agents may induce chromosomal aberrations, such as breaks and gaps. The peccary, Tayassu tajacu is a pig relative that exhibits a very stable karyotype with the only described alterations being of the form of the X chromosome. Chromosomal gaps and breaks were observed at high frequencies during cytogenetics analyses. These alterations were observed in the chromosomes autossomics. Reviews of the literature and of the data described herein suggests that an vermifuge, the ivermectin base, was the most likely cause of these chromosomal alterations. |
