摘    要:为了研究地标(landmarks)是否影响犬蝠(Cynopterus sphinx)的空间记忆,我们通过室内模拟试验研究犬蝠和地标在觅食过程中空间记忆形成的关系。实验组按照每天地标数分别为0、2、4、8、0的数目连续进行5天实验,对照组不设地标进行相同条件的实验。结果显示,两组犬蝠第一次取食所用的时间与实验天数之间极显著相关(Pearson Correlations: 实验组r=-0.593, P<0.01;对照组r=-0.581, P<0.01);实验组取食成功率与实验天数之间无明显相关性(Pearson Correlations: r=0.177, P>0.05);对照组取食成功率与实验天数之间显著相关(Pearson Correlations: r=0.445, P<0.05)。实验组与对照组犬蝠第一次取食的时间差异不显著(GLM: F0.05,1=4.703, P>0.05),两组间取食的成功率差异也不显著(GLM: F0.05,1=0.849, P>0.05)。这些结果说明了随着时间增加,犬蝠对取食地的空间记忆逐渐形成,放置地标在犬蝠对取食地空间记忆形成的过程中无显著影响。

Abstract:In order to study the relationship between landmarks and spatial memory in short-nosed fruit bat, Cynopterus sphinx (Megachiroptera, Pteropodidae), we simulated a foraging environment in the laboratory. Different landmarks were placed to gauge the spatial memory of C. sphinx. We changed the number of landmarks every day with 0 landmarks again on the fifth day (from 0, 2, 4, 8 to 0). Individuals from the control group were exposed to the identical artificial foraging environment, but without landmarks. The results indicated that there was significant correlation between the time of the first foraging and the experimental days in both groups (Pearson Correlation: experimental group: r=-0.593, P<0.01; control group: r=-0.581, P<0.01). There was no significant correlation between the success rates of foraging and the experimental days in experimental groups (Pearson Correlation: r=0.177, P>0.05), but there was significant correlation between the success rates of foraging and the experimental days in the control groups (Pearson Correlation: r=0.445, P<0.05). There was no significant difference for the first foraging time between experimental and control groups (GLM: F0.05,1=4.703, P>0.05); also, there was no significant difference in success rates of foraging between these two groups (GLM: F0.05,1=0.849, P>0.05). The results of our experiment suggest that spatial memory in C. sphinx was formed gradually and that the placed landmarks appeared to have no discernable effects on the memory of the foraging space.
