Abstract
The population density of spiders was investigated in paddy fields and adjacent dikes in Miyagi Prefecture during winter. Most of the spiders hibernated in dikes and their population density reduced markedly during midwinter. The reduction occurred density-independently from November to December, and inverse density-dependently from December to March. This suggests that spiders prefer hibernating in places favorable for survival during midwinter. Straw heaps on dikes contributed to the survival of spiders during winter. The survived spiders were fatally affected by the destruction of vegetation due to repairs of dikes during spring, and their spatial distribution became more even.
