摘要在位于日本寒带地区的小川森林保护区及其附近地区进行的生物多样性监测项目的结果表明，物种丰富度有三种不同的模式。该地区森林的特点是不同树龄的次生落叶林镶嵌在针叶林中。观察到的物种丰富度随林分年龄变化的三种不同类型如下：
第一类(蝴蝶、租管蜂和黄蜂、飞蝇、果蝇和天牛)的物种多样性在空旷地带最高，但随着林龄的增加而减少；第二类(与之相关的蘑菇和螨类)，年龄较大的林分表现出比年轻林更大的多样性；第三类(飞蛾、甲螨、胶虫、甲虫和蚂蚁)，物种数量随着林龄的变化不大，尽管排序分析表明物种组成有变化。这些结果表明，不同树龄的林分组合或异质排列的林分有助于在景观水平上维持昆虫的生物多样性。
AbstractThe results of a biodiversity monitoring program conducted in the Ogawa Forest Reserve and its vicinity, situated in a cool temperate region of Japan, identified three different patterns for species richness. Forests of the region are characterized by a mosaic of secondary deciduous stands of various ages scattered among plantations of conifers. The three different types of change in species richness observed in response to the stand age are as follows:
Type I (butterflies, tube-renting bees and wasps, hoverflies, fruit flies, and longicorn beetles), the species diversity was highest in open areas, just after clear-cutting, decreasing with the stand age;Type II (mushrooms and mites associated with them), older stands showed greater diversity than younger stands; and,Type III (moths, oribatid mites, collembolas, carabid beetles, and ants), the number of species did not change greatly with the stand age, though ordination analysis revealed that there was variation in species compositions. These results indicate that combinations of stands of different ages, or heterogeneously arranged stands, can contribute to the maintenance of insect biodiversity at the landscape level.
