Abstract
Fiddler crabs (Genus Uca) are distributed over most of the eastern coastline of the Americas and the islands of the Caribbean (Rathbun 1918). Although all species have either tropical or temperate zone affinities, there is an area of overlap of some northern and southern forms along the east coast of Florida. In investigating various physiological responses of these fiddler crabs, it is hoped that a clearer picture of the role of physiology in the distribution and ecology of these organisms will be obtained. The present paper in this series is undertaken both to determine the upper and lower thermal death limits of various species of tropical and temperate zone fiddler crabs and to study the influence of acclimation to low temperature on shifting the thermal death points. By using thermal acclimation studies it is possible to determine better whether any difference in response can be explained on the basis of genotypic or phenotypic variation.
