This suggests that both predation attempts and complications with molting play important roles as causes of autotomy in this population.
While there is little doubt that all arthropods capable of autotomy experience high selective pressure due to predation, 2 factors make the cause of autotomy in stick insects particularly interesting.
Next, we measured burst speed of a group of geckos across a wide range in size, both before and after inducing tail autotomy.
The single strike to the tail resulted in the only case of autotomy in the 35 trials that included tailed geckos.
The long, narrow form of the walking legs results in relatively rapid cooling (van Tamelen, 2005), and autotomy is commonly observed in Chionoecetes spp.
Delays in limb autotomy appear to be common among crabs and may have important consequences.
During the current study, we found, unexpectedly, autotomy and spasm of the crabs after histamine injection.
The autotomy rate and spasm rate of the crabs during the experiment were calculated as follows:
in a spider has minimal costs in competitive ability and development.
The experiment only indicated whether loss of the radial nerve causes arm autotomy.
Experimentally severing the radial nerve caused partial arm autotomy in 3 of the 27 L.
