- Autotomy, the strategy of voluntarily releasing a leg during an encounter with a potential predator or in agonisticinteractions between conspecifics, is common in animals. The potential costs of this behavior have been scarcely studied. Inaddition, locomotion and substrate-dependent performance might be affected by autotomy. We did a comparative andobservational study to investigate whether losing legs affects the escape speed and trajectory of harvestmen in the genusPrionostemma Pocock, 1903 (Eupnoi: Sclerosomatidae) on different substrates: soil (the least roughened), smooth bark andmossy bark (the most roughened) in a tropical premontane forest in Costa Rica. We observed that 71% of the individualsfound were missing at least one leg. Harvestmen, regardless of leg condition, walked faster and made fewer turns in theirtrajectory in the soil. While climbing, they were faster on smooth bark than in moss. On all substrates, autotomizedindividuals were slower and had a more erratic trajectory than intact ones. The type of missing legs (sensory or locomotor)had no influence on the speed or trajectory. We experimentally induced autotomy and found that walking speed on soildecreases if individuals lose a leg. Our findings confirm that losing legs affects locomotion, and we provide novel insightson how locomotion in these harvestmen depends on surface roughness. Our data suggest that moss could be a type ofsubstrate that requires more elaborate skills in balance, orientation and texture recognition than smooth bark.
