Abstract:
The results of the first series of
multidisciplinary investigations of the Caribbean barrier reef complex near
Carrie Bow Cay, Belize, are reported in 34 papers in this volume, which
begins with a summary of past work on the Belizean reefs and cays. The first
section treats the structure of barrier reef habitats in the vicinity of Carrie
Bow Cay, influential physical parameters such as tides and currents, geological
and sedimentological history of lagoon, reef, and island substrates, and the
island's environment, including its climate and the effects of hurricanes. Subsequent papers analyze the distribution of endolithic microorganisms in
carbonate substrates, and the diversity, standing crop, and production in
selected lagoon and back-reef habitats. Related contributions report on the
benthos of an unusual submarine cave and on the surface zooplankton over
reef and lagoon bottoms. One section is devoted to the systematics and local
distribution of flora and fauna. Marine plants covered are plankton diatoms,
benthic algae—including a detailed study of the red alga Polysiphonia—and
sea grasses. Faunistic studies focus on hydroids, medusae, stony corals, octocorals, sipunculans, anthurid isopods, pycnogonids, a marine chironomid, ophiuroids, and crinoids. In the papers on Polysiphonia, hydroids, stony corals,
and anthurids, all species are illustrated for identification by nonspecialists;
figures of important or unusual examples are shown in the other systematic
contributions. New species are described among anthurids, pycnogonids, and
ophiuroids. A section on ecological responses discusses the reaction of algae to
grazing pressure, the life history of an ichthyo-parasitic hydroid, the growth
response of the reef coral Montastrea annularis to a light gradient, and associations between zoanthids and their sponge hosts. Included in this section are
discussions of the ecology of the zoanthid Isaurus duchassaingi, settlement
behavior and development of the bivalve Malleus candeanus, and behavioral
ecology of two closely related reef fishes, genus Acanthemblemana. The volume
concludes with two general surveys of the barrier reef and cays, which discuss
the Carrie Bow reef section and cay in relation to the overall barrier reef
complex.
