The structural complexity of a habitat dictates the availability of shelter, and shelter may affect population and community structure in many systems. I tested predictions from the shelter bottleneck hypothesis, which proposes that shelter (or refuge) limitation can control population size structure and density by acting strongly on only one size class. I manipulated shelter for stone crabs in four haphazardly chosen bays in the northeast Gulf of Mexico to examine the shelter bottleneck hypothesis in a mixed-model design. I also examined four biotic factors (habitat structure, food, predation...
