Adaptive Significance of Reproductive Cycles in the Fiddler Crab Uca pugilator: A Hypothesis.
Semimonthly peaks in courtship behavior of male crabs coincide with peaks in the temporal distribution of receptive females. Females mate once each month, 4 to 5 days before one of the semimonthly spring tides. The relation of the time of reproduction to tide cycles may be an adaptation to increase to a maximum the probability that the final stage of the planktonic larvae will be transported by...
متن کاملMolecular phylogeny analysis of fiddler crabs: test of the hypothesis of increasing behavioral complexity in evolution.
The current phylogenetic hypothesis for the evolution and biogeography of fiddler crabs relies on the assumption that complex behavioral traits are assumed to also be evolutionary derived. Indo-west Pacific fiddler crabs have simpler reproductive social behavior and are more marine and were thought to be ancestral to the more behaviorally complex and more terrestrial American species. It was al...
متن کاملFiddler crabs
What are fiddler crabs? Fiddler crabs belong to the genus Uca. They are members of the ocypodid family of brachyuran crabs, the most recent marine animals to have invaded land. They spend the first part of their life as aquatic plankton and only settle in the intertidal zone after their last larval moult. Adults live in burrows on intertidal mudand sand-flats within dense, mixedage, mixed-sex a...
