Metabolic costs of the predation strategy of the spider Pardosa amentata (Clerck) (Lycosidae)
Pardosa amentata adopts a “sit-and-wait” predation strategy with periodic changes of site. The metabolic costs of this strategy were evaluated using a Gilson respirometer. The respirometer was run at the mean te...
