Hermit crabs
Researchers had been divided over whether the sound was vocal or not, but the latest study, published online in the Royal Society Proceedings B shows unequivocally that the tail feathers were the source of the sound. When the researchers cut back the tail feathers — which grow back in five weeks and do not affect the birds ability to fly — the males were unable to make the noise. Tests in wind ...
متن کاملOn hermit crabs and humans.
Flynn, Laland, Kendal and Kendal’s article (this issue) plays a valuable role in two ways. First, it demonstrates how developmental psychology can learn lessons from the latest research on developmental niche construction within evolutionary biology. Secondly, for those psychologists whose main focus is the cognitive mechanisms by which humans develop their particular suite of abilities, it is ...
متن کاملShell Exchange in Hawaiian Hermit Crabs
Shell exchange behavior of intertidal Hawaiian hermit crabs was observed in the laboratory. Outcomes of 255 shell-related interactions were analyzed to test the predictive powers of two models of resource exchange . In the case of intraspecific interactions, the negotiations model (which predicts that exchanges should occur only when both crabs will gain in shell value) was superior to an aggre...
متن کاملLocomotion of Hermit Crabs (coenobita Compressus) on Beach and Treadmill
Coenobita compressus (H. Milne Edwards) walk forward on six legs using an alternating tripod gait similar to that of insects. The first walking leg provides the driving force for locomotion aided secondarily by the second walking leg, while the chelipeds act largely as supports. The left appendages are longer and heavier than the right, and they extend further laterally from the midline during ...
متن کاملNiche construction drives social dependence in hermit crabs
Organisms can receive not only a genetic inheritance from their ancestors but also an ecological inheritance, involving modifications their ancestors made to the environment through niche construction. Ecological inheritances may persist as a legacy, potentially generating selection pressures that favor sociality. Yet, most proposed cases of sociality being impacted by an ecological inheritance...
