Valve length growth rates (Table 3) show that horse mussel populations from sand with bioherm
and gravel/scallop bed geological provinces grow faster during the first 4 years of life.
schmitti population analyzed here occupy the largest tubes at their disposal in the bioherm
, and size in both sexes was positively correlated with tube opening, suggesting that crabs must change their housing with growth (Gherardi and Cassidy, 1994b).
biotas commonly differ from surrounding flat-bottom communities.
thought to occur inside the OHAPC, and a portion of bioherms
outside the OHAPC between the two satellite areas (Fig.
(algal ridges and bank-barrier reefs) of the eastern Caribbean.
Field observations suggest that the fossiliferous horizon is dominated by in situ oyster bioherms
The structure of the Porkuni Stage is also complicated by hiatuses, but for the purposes of this paper it is significant to note shallow shelf bioclastic limestones with stromatoporoid-tabulate bioherms
and interreef beds of oolitic and kerogenous limestones.

Coral reefs are a special case of bioherms
, or wave-resistant calcium carbonate structures of biological origin.
In addition, stony corals formed huge mounds, known as bioherms
The reef facies with massive algal bioherms
might have formed in an up to 700 km long and 3-5 km wide distinctive facies belt on the shelf edge (Sennikov et al.
