Body size affects the spatial scale of habitat-beetle interactions
Article Abstract:
A study was conducted to determine the spatial scale at which 31 species of longhorned beetles respond to forest habitat amount. It was predicted that the spatial scale at which species respond would increase with body size, and that species using ephemeral larval habitat would respond at larger spatial scales than species using more stable larval habitat.

Habitat loss decreases predator-prey ratios in a pine-bark beetle system
Article Abstract:
The hypothesis that the ratio of abundance of predators to prey should decrease with increasing habitat loss at the landscape scale is tested using a pine-bark beetle ecosystem as a model. Ten red pine sites are selected that represent extremes of available habitat within a 2 km radius surrounding each stand.

The relative importance of spatial aggregation and resource partitioning on the coexistence of mycophagous insects
Article Abstract:
The relative importance of spatial aggregation and resource partitioning on coexistence is investigated for mycophagous insects in central Japan. The effects of spatial aggregation and resource partitioning are separated by a randomization procedure.
