摘要
2001年9～12月,在四川省都江堰林区实验围栏内研究了栓皮栎、树、栲树、石栎、青冈和油茶种子与6种埋藏深度对小泡巨鼠雌性成体发现埋藏种子的影响。结果表明:1)由于不同种子在种子大小、营养价值和单宁含量等存在差异,雌性小泡巨鼠对个体最大的石栎种子发现率最高,油茶(脂肪含量高)和栲树(单宁含量低)次之,单宁含量较高的树、青冈和栓皮栎则较低;2)埋藏深度与雌性小泡巨鼠发现栓皮栎种子的比例呈显著负相关,即随着埋藏深度增加,小泡巨鼠发现埋藏种子的比例则减少。
From September to December of 2001, two experiments were conducted to study the effects of seed species (Quercus varialilis, Q. serrata, Castanopsis fargesii, Lithocarpus harlandii, Cyclobalanopsis glauca, and Camellia oleifera) and burial depth (0-1 cm, 1-2 cm, 2-4 cm, 4-6 cm, 6-8 cm and 8-10 cm) on seed recovery in the arenas by female adult Edward's long-tailed rats (Leopoldamys edwardsi), a dominant rodent species in the forest of Dujiangyan Region of Sichuan Province, China. The results showed that: 1) Due to the variation in seed size, nutrient value and tannin content among the six tree seed species, the seed species did significantly influence seed recovery by female adults:the highest for L. harlandii seeds (the biggest seeds), second for Camellia oleifera (high fat content) and Castanopsis fargesii (low tannin content), and lower for the other three seed species (high tannin content); 2) There was a significantly negative correlation between burial depths and seed recovery of Q. varialilis by female adults. That is, female adults recovered the lower proportion of seeds as the seeds were buried deeper from 0-1 cm to 8-10 cm.
