摘要
舔食盐分是野生动物的常见习性,但针对具体物种的研究较少.我们于2013年秋季(9～10月份)利用4台红外触发相机在唐家河国家级自然保护区对小麂(Muntiacus reevesi)利用人工盐场的时间格局进行了初步研究.共收集照片记录398条,其中可鉴别性别的记录288条.结果显示,小麂日均访问盐场(12.97±2.14)次,舔盐高峰出现在8:00 ～ 9:00时以及14:00～ 16:00时,低谷分别出现在2:00时、6:00时以及21:00 ～ 23:00时.独立样本t检验显示,小麂对距离公路较远的盐场访问次数显著高于近公路盐场[远离公路盐场(10.86±2.25)次,近公路盐场(2.10±0.58)次,t=3.77,P=0.001].不论以全天统计抑或按照不同时间段(上午、下午和夜间)分别统计,雌雄两性对盐场的利用强度均无显著差异.我们仅发现在13:00～ 17:00时,雄性访问盐场的强度显著高于雌性(t=-2.47,P=0.048),且在13:00～ 14:00时和15:00～16:00时出现两次访问高峰.我们推测性别间的活动节律差异、体型差异以及雄性的干扰,均可能是雌性在下午时段降低盐场利用的原因.人为活动对离公路近的栖息地干扰较强,因而影响了小麂对栖息地的利用,使小麂回避靠近公路的盐场.因此,我们建议自然保护区在选择盐场位置时应考虑人为干扰因素.
Abstract
Licking salt at natural or artificial salt sites is common in ungulates,but little is known about Chinese muntjac (Muntiacus reevesi).We preliminarily studied the rhythm of muntjac visiting artificial salt sites by using 4 infrared cameras with two distance level to road (50 m vs.150 m) within broadleaf forest in Tangjiahe Nature Reserve from September to October in 2013.Totally,we collected 288 valid records,in which male and female can be clearly identified.Muntjac visited salt sites 12.97 ± 2.14 times daily,with two visiting peaks from 8:00 am to 9:00 am and 14:00 pm to 16:00 pm respectively.However,the muntjac seldom visited salt sites at 2 am and 6 am in the early morning and 9:00 pm to 11:00 pm during the night.We observed Chinese muntjac visited the salt sites located far from road (150 m) more frequently than they did to sites that close to road (50 m,10.86 ± 2.25 vs.2.10 ± 0.58,t =3.77,P =0.001).Female and male muntjac showed a similar salt lick visiting temporal pattem during night and no significant difference of visiting times was detected either calculated by day or by separated periods (moming,afternoon and night).The only difference of rhythm found between sex visiting salt sites was 13:00-17:00.Thus,male visited salt sites more frequently than female (t =-2.47,P =0.048) and two visiting peak observed during 13:00-14:00 and 15:00-16:00.The results indicated that human disturbance might be a factor hindered muntjac using related habitat and therefore impact their utilization of minerals.Female exhibit lower salt lick frequency during aftemoon than male might be induced by activity rhythm variation and body weight variation between sexes,as well as male disturbance.Based on this study,we recommend nature reserve should consider human disturbance when setting artificial salt licks for the Chinese muntjac and other ungulates.
