为了研究城市化进程如何影响城市中蚂蚁物种的分布，我比较了东京（日本最密集的城市地区）及其发展中的邻居千叶市不同地区和年龄的城市公园中蚂蚁物种丰富度。在98个公园共发现43种蚂蚁。多元回归分析表明，公园面积和年龄有积极的影响，在公园的蚂蚁物种的数量，在东京的公园比同类公园在千叶包含较少的物种。因此，城市化的进程减少了城市公园中的蚂蚁物种丰富度，很可能是因为它将公园与周围地区隔离开来。接下来，为了考察城市地区的地形变化类型与蚂蚁分布之间的关系，比较了千叶市不同地形类型（高地+梯田、低地、挖填、堤岸、填海）的城市公园中蚂蚁物种丰富度。这项研究表明，在开垦的土地和低地的公园比其他地区的公园包含更少的蚂蚁物种。这种下降的蚂蚁区系的原因进行了讨论。
To investigate how progressive urbanization influences the distribution of ant species in cities, I compared the ant species richness in urban parks of different areas and ages of Tokyo, the most intensively developed urban region in Japan, and its developing neighbor, Chiba City. A total of 43 ant species were found from 98 parks. Multiple regression analysis revealed that park area and age had a positive effect on the number of ant species in the parks and that the parks in Tokyo contained fewer species than did comparable parks in Chiba. Thus, the progression of urbanization reduces ant species richness in urban parks, most likely because it isolates the parks from the surrounding area. Next, in order to examine the relationships between the types of landform modification and the ant distribution in urban areas, I compared the ant species richness in urban parks of Chiba City among different landform types (upland + terraces, lowlands, cut and fill, banking, and reclamation). This study showed that the parks in the reclaimed lands and lowlands contained fewer ant species than did parks in other areas. The reason for this decline of ant fauna is discussed.
