摘要：我们测量了 5 月至 9 月 34 个金鼠 (Ochrotomys nuttalli) 树栖巢点和 34 个配对随机地点的栖息地特征。 1997。两种类型的地点之间的微生境存在显着差异。在所测量的 12 个栖息地特征中，有 5 个特征中，树栖巢址与随机地点不同，包括：更多的攀缘藤蔓和木本植被，更大的水平植被覆盖度（通过距巢穴 3 m 和 6 m 距离且更靠近林下树木的密度板测量）。树栖巢穴中茂密的植被可以增强对捕食者的保护，增加巢穴附着的基质，免受恶劣天气的影响，并具有温度调节优势。增加金鼠出没地区林下植被密度的管理策略将通过改善筑巢栖息地、增加补充和生存来增加种群数量。
Abstract We measured habitat characteristics at 34 arboreal nest sites of golden mice (Ochrotomys nuttalli) and 34 paired random sites from May–Sept. 1997. Microhabitat was significantly different between the two types of sites. Arboreal nest sites differed from random sites in 5 of the 12 habitat characteristics measured including: more climbing vines and woody vegetation, greater horizontal vegetative cover as measured by a density board at a distance of both 3 m and 6 m from the nest and closer to understory trees. The presence of thick vegetation at arboreal nest sites may provide increased protection from predators, increased substrate for attachment of nests, protection from inclement weather and thermoregulatory advantages. Management strategies that increase the density of understory vegetation in areas where golden mice occur will enhance populations by improving nesting habitat and increasing recruitment and survival.
