Life span, reproductive output, and reproductive opportunity in captive Goeldi’s monkeys (Callimico goeldii)
Abstract 10.1002/zoo.20239.abs In the absence of long-term field studies, demographic and reproductive records from animals housed in zoos and research laboratories are a valuable tool for the study of life history variables relating to reproduction. In this study, we analyzed studbook records of more than 2,000 individuals born over a 40-year period (1965–2004) to describe […]
Cumulative stress in research animals: Telomere attrition as a biomarker in a welfare context?
Progress in improving animal welfare is currently limited by the lack of objective methods for assessing lifetime experience. I propose that telomere attrition, a cellular biomarker of biological age, provides a molecular measure of cumulative experience that could be used to assess the welfare impact of husbandry regimes and/or experimental procedures on non-human animals. I […]
