Sampling comments: sampling was "during the growing seasons of 1999-2001" and each plot was planted with rice and fertilized, but "No insecticides or fungicides were applied... From July to September of each year, the abundance of spiders and other arthropods in each plot was surveyed using the cylinder method... Once every 10 d, ten hills were systematically selected in each plot... and enclosed by forcing a metal frame... into the soil. All spiders and other arthropods... were then collected using a suction apparatus"
counts of juveniles, mostly indeterminate at the genus level, are not entered
