摘要

摘要日本猕猴(Macaca fuscata)的栖息地已被人类活动所改变,如森林砍伐、针叶树种植、农业化和森林破碎化。这种改变可能会影响猕猴的栖息地使用。我们研究了两支猕猴部队的栖息地使用情况:一支“森林部队”和一支“农田部队”。我们关注的是森林边缘,以前没有将其归类为栖息地类型。两支部队在秋季经常使用落叶阔叶林,在夏季经常使用森林边缘。森林部队经常使用森林草原边缘,而农田部队经常使用林地边缘。夏、秋、冬三季,农田部队落叶阔叶林的选择指数均显著高于森林部队。由于日本猕猴是森林居民,并且倾向于避开开阔地带,因此两支部队可能都更频繁地使用森林。与此同时,由于针叶树种植园的建立,森林中的粮食资源减少,而农业化,粮食资源增加,这可能导致猕猴更频繁地使用森林边缘。森林边缘应被视为一个独立的栖息地,以便准确评估猕猴栖息地的使用情况。

Human Effects on Habitat Use of Japanese Macaques (Macaca fuscata): Importance of Forest Edges
Abstract. Habitats of the Japanese macaque (Macaca fuscata) have been modified by human activities such as deforestation, conifer plantation, agriculturalization, and forest fragmentation. Such modifications likely affect habitat use of the macaques. We examined the habitat use of two macaque troops: a “forest troop” and a “cropland troop”. We focused on forest edges, which have not been previously categorized as a habitat type. Both troops frequently used deciduous broad-leaved forest in autumn and forest edges in summer. The forest troop frequently used forest-grassland edges, whereas the cropland troop frequently used forest-cropland edges. The selection index for the deciduous broad-leaved forest of the cropland troop exhibited significantly higher values than those of the forest troop in summer, autumn, and winter. Since the Japanese macaque is a forest-dweller and tends to avoid open areas, both troops may have used forests more frequently. Meanwhile, a decline in food resources in the forest due to the establishment of conifer plantations and an increase in food resources due to agriculturalization may have led to more frequent use of forest edges by the macaques. Forest edges should be treated as an independent habitat for accurate assessment of macaque habitat use.
