Costs associated with leg autotomy in the harvestmen Leiobunum nigripes and Leiobunum vittatum (Arachnida: Opiliones)

摘要: The benefits of autotomy appendages are usually obvious but the costs often less apparent. This study reports effects leg on mobility, foraging ability, and sensory perception in two species harvestmen, Leiobunum nigripes vittatum (Opiliones: Sclerosomatidae). running speed both was recorded a test track. Individuals with only 5 legs were significantly slower than those 6 or more legs. mobility abilities L. tested by recording time it took for them to find eat chilled flies (Drosophila virilis). Those harvestmen spent moving did longer food 7 8 These results indicate that significant reductions ability occur after loss 3 Also, eaten sooner contact either fi...
