Dispersal distances of 17 species of butterflies in tropical Singapore were significantly greater in forest than in urban habitat. Butterflies in urban plots frequently moved within suitable habitat (park/grassland) patches but rarely crossed non‐habitat patches suggesting potential isolation and a need for urban corridors.

栖息地对城市景观中热带森林，公园和草地斑块中蝴蝶扩散的影响

在新加坡热带地区，森林中17种蝴蝶的扩散距离明显大于城市栖息地。城市地块中的蝴蝶经常在合适的栖息地（公园/草地）内移动，但很少越过非人居地，表明潜在的隔离和对城市走廊的需求。
