了解林业的长期影响，即，古老的原生森林转变为第二次生长的原生森林或针叶树种植园，对蚂蚁物种丰富度的影响（即，对日本西南部四国岛满川流域5个120年以上的原始林、4个30-70年的次生林和3个30-40年的针叶林的蚂蚁群落进行了比较。收集到的蚂蚁种类共计39种。原生林、次生林和人工针叶林的蚂蚁种类数分别为10-20种、15-20种和11-15种。蚂蚁物种丰富度总体上没有受到森林转换的影响。然而，对应分析（CA）表明，原始林和改造林（次生林和针叶树人工林）之间的蚂蚁物种组成存在显着差异。林地专家的物种丰富度更大的原始森林，和开放的栖息地专家和栖息地通才占主导地位的转换森林。森林对蚂蚁群落的影响持续时间较长。采伐后40-70年更新的次生林的蚂蚁群落与原始林的蚂蚁群落仍有差异。必须认真管理与原始森林遗迹接壤的次生林，以防止开放生境的蚂蚁物种侵入原始森林内部。
To understand the long-term impacts of forestry, i.e., the conversion of old-growth native forests to second-growth native forests or conifer plantations, on ant species richness (i.e., the number of species) and species composition, ant assemblages from five old-growth forests (more than 120 years), four second-growth forests (30–70 years) and three conifer plantations (30–40 years) were compared in the Shimanto River Basin, Shikoku, southwest Japan. The number of ant species collected totaled 39. The number of ant species from the old-growth native forests, second-growth native forests and conifer plantations was 10–20, 15–20 and 11–15, respectively. The overall ant species richness had not been affected by forest conversion. However, correspondence analysis (CA) showed that the ant species composition was markedly different between old-growth forests and converted forests (second-growth forests and conifer plantations). The species richness of woodland specialists was greater in the old-growth forests, and open-habitat specialists and habitat generalists dominated the converted forests. The impacts of forestry on ant assemblages were of a long duration. Ant assemblages of the second-growth forests under regeneration for 40–70 years after logging were still distinct from those of old-growth forests. Careful management of second-growth forests bordering old-growth remnants would be essential to prevent the invasion of open-habitat species of ants into the interior of old-growth forests.
