黑麂栖息地利用的季节变化

动物对栖息地的利用和选择是研究动物生境需求的核心内容。它可以为栖息地评价、容纳量估计、能量代谢以及种间关系等研究提供有价值的基础资料,也对重建、恢复和管理野生动物尤其是濒危动物栖息地具有参考价值。以往有关黑麂生态学的研究主要集中在种群特征、食性、繁殖、人工驯养和资源状况等方面(欧善华等,1981;盛和林等,1987,1990,1992;鲍毅新,2002;吴海龙等,2003),对黑麂栖息地的利用只有简单的描述(盛和林,1987,1992),没有系统的定量化报道。故从2002年4月至2003年12月在浙江省九龙山自然保护区和古田山自然保护区开展了黑麂栖息地利…

Seasonal changes in habitat use of black muntjac (Muntiacus crinifrons)in Zhejiang

We s tudied seasonal habitat use of black muntjacs in the Jiulong Mount ain and Gutian Mountain Nature Reserves in Zhejiang Province, April 2002-Decembe r 2003 based on indirect sign (e.g., tracks, feces). We assumed that abun dance of sign functioned as a surrogate for intensity of use. During the 20-mon t h sampling period, we quantified 11 ecological factors in 141 sample plots. Black muntjac vegetation use varied significantly with season. Variati on in muntjac use of vegetation types were primarily related to seasonal changes of food resources and concealment conditions. Durin g spring, autumn and winter, muntjacs mostly used middle and lower portions of mountainsides, whereas they used upper portions of mountains during summer. Varying seasonal use of elevation mos t likely accounted for slope effects. We found no evidence of seasonal va riation in muntjac use of slope, aspect, rock exposur e, distance from water or level of human disturbance.
