Marine habitats with limited refugia from predation but adequate
food may support increases in prey abundance if artificial
shelters placed in these habitats reduce predation-induced
mortality. Moreover, the protective capacity of shelters may vary
according to the scaling between shelter size and prey size. We
tested these hypotheses with field tethering experiments in Bahia
de la Ascension, Mexico, by examining the impact of
different-sized artificial shelters upon mortality rates of 3
juvenile size-classes of the Caribbean spiny lobster Panulirus
argus at 2 sites (inner-bay sand-seagrass flat and outer-bay
seagrass bed adjacent to coral reefs). The artificial shelters
were sunken concrete structures (cositas) that simulate lobster
dens. In the tethering experiments, spiny lobster survival was (1)
higher in casitas than seagrass meadows, irrespective of casita
size; (2) generally higher in smaller than larger casitas, though
the effect depended upon the relationship between lobster and
shelter size; and (3) independent of site.
