| 中文摘要: |
| 根据鳞甲、毛发、爪的磨损程度以及母幼行为关系和体重大小,对2011年6月查获的87头马来穿山甲(Manis javanica)种群结构进行了分析,幼年、亚成年、成年、老年组分别由3(3.45%)、22(25.29%)、32(36.78%)和27(34.48%)个体组成,年龄结构呈倒金字塔型,属快速下降型种群。种群性比(♀:♂)为1:1.42(36:51),雌性比例少。年龄组中成年组雌性比例最少(28.13%)。每胎1仔,体重最小的孕兽1.95kg,为亚成年个体。雌兽群体怀孕率为36.1%,成年组雌兽怀孕率最高(77.78%),繁殖力最强。新生仔兽体重、体长、尾长分别为143.3±6.67g(120~170g,n=6)、14.7±0.29cm(14.8~15.4cm,n=6)和10.1±0.24cm(9.5~11.2cm,n=6)。研究结果表明,马来穿山甲种群结构已受到较大程度破坏,处于较为严重的不健康状态,如果不采取有效保护措施,将会继续朝着快速下降的趋势发展,甚至会在较短的时间内生态灭绝。 |

| We obtained 87 living Malayan pangolins (Manis javanica) that the Forestry Public Security Bureau of Guangdong confiscated from illegal trader in June, 2011. According to the wear degree of their claws, scales and hair, the behavior relationships between mother and baby, and body weight, they were divided into 4 age groups: cub, sub-adult, adult and senior, and were composted of 3(3.45%), 22(25.29%), 32(36.78%) and 30(34.48%) individuals respectively. The age structure diagram shaped inverse pyramid, it implied Malayan pangolin population was in rapid decline. Sex ratio was 1:1.42(♂:♀)(36:51). The proportion of females was less than that of males, and the female proportion was the lowest in adult group (28.13%). The giving birth records showed one cub at a birth. The pregnancy rate for all females was 36.1%, the greatest fecundity occurred in the adult group (77.78%). The smallest pregnant mother (sub-adult) was 1.95kg in weight. Morphological feature for new born cubs were measured: body weight 143.3±6.67g (120~170g, n=6); body length 14.7±0.29cm(14.8~15.4cm, n=6); tail length 10.1±0.24cm (9.5~11.2cm, n=6). Our research results show in Southeast Asia area Malayan pangolin population has been largely destroyed with severe unhealthy status, if we don’t take effective protective measures, the population will continue to keep a rapid decline trend, even the ecocide is possible as well in near future. |
