捕获和圈养自由放养的灵长类动物给研究人员带来了很多好处，但对个体来说，实际和潜在的成本也是如此。我们的目标是1)定量地评估对自由活动的灵长类物种进行无线电项圈的可能的人口学长期成本，以及2)定性地评估受试者的成本以及多年来监测大量有项圈个体的群体对研究计划的总体好处。在2000至2009年间，我们捕获、重新捕获了146只猫头鹰猴子(Aotus Azarai)，并将其戴上无线电项圈，以研究该物种的行为、人口学和遗传学。为了评估圈养程序对种群的潜在长期成本，我们比较了核心研究区域中种群(n = 20)和同一森林内对照区域中未受干扰的种群(n = 20)的人口构成。这两个地区的种群大小在2到5只之间。令人惊讶的是，研究组的群体规模往往更大，因为这些组的婴儿和青少年比对照组多。研究计划的好处包括可靠的个体识别、增加样本大小、标本回收、扩散研究、外展活动和保护教育。尽管如此，只有当项目按时持续、得到地方当局的充分批准和支持、并有广泛的社区参与以及保护和教育目标时，一些好处才会变得切实。因此，任何抓捕和束缚个人的严肃举措都应该是对收益和成本进行极其仔细的评估的结果。
The benefits to researchers of capturing and collaring free-ranging primates are numerous, but so are the actual and potential costs to the individuals. We aimed to 1) evaluate quantitatively the possible demographic long-term costs of radio-collaring a free-ranging primate species, and 2) evaluate qualitatively the costs to the subjects and the overall benefits to the research program that results from monitoring a large number of groups with collared individuals during many years. Between 2000 and 2009, we captured, recaptured, and radio-collared 146 owl monkeys (Aotus azarai) to study the behavior, demography, and genetics of the species. To evaluate the potential long-term costs of the collaring procedures on the population, we compared the demographic composition of groups (n = 20) in our core study area with those of undisturbed groups (n = 20) in a control area within the same forest. Groups in both areas ranged in size between 2 and 5 individuals. Surprisingly, group size tended to be larger among the study groups owing to more infants and juveniles in those groups than in the control groups. The benefits to the research program have included, among others, the reliable identification of individuals, increased sample sizes, the recovery of specimens, studies of dispersal, outreach activities, and conservation education. Still, some of the benefits will become tangible only when the project persists on time; is fully approved and supported by local authorities; and has broad community participation, as well as conservation and education goals. Thus, any serious initiative to capture and collar individuals should be the result of an extremely careful evaluation of benefits and costs.
