Estimation of the walking ability of an exotic terrestrial isopod Armadillidium vulgare Latreille by field and laboratory measurements

摘要

Migration distance is an important determinant of the distribution area of animals and is an important factor influencing community structure. However, a few studies have reported the walking distance of terrestrial isopods. The walking distance of anexotic terrestrial isopod Armadillidium vulgare (Latreille, 1804) was analyzed by field and laboratory measurements. A mark-and-recapture field survey indicated that A. vulgare could walk 24 m per day and up to 51m over 8 days. Moreover, this species walked about 50 m in one hour under experimental conditions (0.8 lux, 22°C). The walking ability of A. vulgare is similar to the migration distances of flying beetles and a grasshopper.
