Abstract

Leucism is the lack or reduction in pigmentation in the most or parts of the body, but not in the eyes and body extremities. It is extremely rare in primates and has never been reported for Callithrix, a genus endemic to Brazil. We searched for individuals of Callithrix jacchus and C. penicillata with pigmentation anomalies in a systematic survey of three protected areas in the Atlantic Forest, within museum collections in Brazil, and opportunistically during field studies. Since 2008, we have recorded 8 individuals with leucism in small urban and periurban forest patches. Four were from native populations of C. penicillata in Cerrado savannahs and of C. jacchus in the Caatinga xeric scrubland, and 4 were from populations of hybrids between C. jacchus and C. penicillata in invaded areas in the coastal Atlantic Forest. We found no pigmentation abnormalities in museum specimens. We hypothesize that the observed leucism may be linked to inbreeding within the native range, but to hybridization within the invaded range, and discuss the likely ecological consequences to leucistic individuals.

巴西入侵和本地绒猴、紫绒猴、青绒猴(灵长类动物，绒猴科)及其杂种的异常色素沉着

白色症是指身体大部分或部分缺乏或减少色素沉着，但眼睛和四肢没有。它在灵长类动物中极为罕见，并且从未报道过巴西特有的Callithrix属。我们通过对大西洋森林三个保护区、巴西博物馆藏品的系统调查，以及在实地研究期间的机会性研究，寻找具有色素沉着异常的青霉和青霉。自2008年以来，我们在城市和城市周边的小森林斑块中记录了8个白化个体。其中4份来自塞拉多草原青霉和Caatinga干旱区灌丛的青霉本地种群，4份来自大西洋沿岸森林入侵区青霉与青霉杂交种群。我们在博物馆标本中未发现色素沉着异常。我们假设观察到的亮色现象可能与本地范围内的近亲繁殖有关，但与入侵范围内的杂交有关，并讨论了亮色个体可能产生的生态后果。

期刊介绍： Recognizing that research in human biology must be founded on a comparative knowledge of our closest relatives, this journal is the natural scientist''s ideal means of access to the best of current primate research. ''Folia Primatologica'' covers fields as diverse as molecular biology and social behaviour, and features articles on ecology, conservation, palaeontology, systematics and functional anatomy. In-depth articles and invited reviews are contributed by the world’s leading primatologists. In addition, special issues provide rapid peer-reviewed publication of conference proceedings. ''Folia Primatologica'' is one of the top-rated primatology publications and is acknowledged worldwide as a high-impact core journal for primatologists, zoologists and anthropologists.
