“…size, life cycle, reproduction strategies) in association with a lack of living space to such a degree that immigration of rare species would only occur with an increase in the abundance of drift colonies. On the other hand, according to Lindberg (1980) and Lindberg & Frydenborg (1980), the head size and architecture of colonies could determine the primary resource value by crabs because the mobility, refuge from predation, critical life cycle phases and positive correlation between crab size and head size.…”

“…Short inter-patch distances in Mixed and Close plots, as compared to Wide plots, should result in greater encounter rates among crabs. Increased encounter rates under (2), the agonistic hypothesis, should increase the emigration of losers or subordinates (Lindberg & Frydenborg 1980). Asymmetries in size, sex and residency contribute to dominance in stone crabs; larger crabs, males, and residents have the advantage (Sinclair 1977).…”

Refuge dspersion was manipulated for a hybrid stone crab population (Menippe rnercenaria X M, adina) in the northeastern Gulf of Mexico. Den quality and quantity were controlled with prefabricated concrete modules (77 X 58 X 30 cm), each representing a resource (i.e. refuge) patch. Inter-patch distances differed among 3 treatments: a widely spaced, uniform patch pattern ('Wide'), an intermediate or mixed patch pattern ('Mixed'), and a closely spaced, uniform patch pattern ('Close'). Wide modules harbored significantly more crabs and larger crabs than &d Mixed or Close modules. Sex ratios &d not differ among treatments, but Wide modules harbored proportionately more mated pairs. Tagged crabs were not long-term residents of a single den, but crab resightings differed among treatments and were greater for females than males. We suggest that prey depletion on soft bottom is a function of refuge dispersion, and that the resulting resource mosaic determines local abundance of stone crabs, residency patterns by size and sex, and male mating success.

“…Lindberg and Stanton (1988) found a similar number of decapod species (23) in colonies of Schizoporella pungens in Florida, with 90.5% of the individuals represented by 21.7% of the species in S. pungens, whereas 91.7% of the decapods of S. errata were represented by 41.7% of the species, almost a two-fold difference. These differences could be due to an active defense of S. pungens colonies by the dominant Pilumnus sayi, as they consitute the only rigid habitat in an area dominated by seagrasses (Lindberg and Frydenborg, 1980). In Brazilian shores, other biogenic substrates are available together with S. errata, and these resources may be less limiting for the crabs.…”

The macrofauna associated with the bryozoan <i>Schizoporella unicornis</i> in southeastern Brazil

SUMMARY:The invertebrate fauna associated with colonies of the bryozoan Schizoporella errata was studied at two sites differing in hydrodynamism in southeastern Brazil. Patterns of species distribution, abundance, and diversity were similar at both sites. Polychaetes dominated the assemblages, both in number of individuals and species, with 70 species distributed in 20 families. Decapod crustaceans were also abundant, mainly anomuran crabs and caridean shrimps. Cluster analysis separated the samples from each site, and further analysis indicated that an interaction between water movement and trophic structure could explain these differences. At the site with low water movement, more muddy sediments were found inside the colonies, and a greater proportion of deposit-feeders was found. At the other site, higher hydrodynamism resulted in less sediments within the colonies, and favoured the occurrence of more filter-feeders. The trophic structure of faunal assemblages can help understand the structure of assemblages associated with biogenic substrata, as already demonstrated for benthic communities.
