Sex Allocation in the Caribbean Coral, <em>Porites astreoides</em> (Lamarck)
… biology of the hermaphroditic coral <em>Porites astreoides</em>, and to determine whether sex allocation varies with colony size or along a light-energy gradient. Tissue samples were collected at depths of 6, 13, 18 and 27 m and the surface area of each colony was measured. Tissue samples …

The Role of Mucus in the Ultraviolet Radiation Protection of <em>Porites astreoides</em>
… changes in UVR exposure?</p> <p>Colonies of <em>Porites astreoides</em> located at Rainbow Gardens (23.47.783N, 76.08.787W) and North Norman's (23.47.373N, 76.08.267W) patch reefs adjacent to Lee Stocking Island, Bahamas were either exposed to, or protected from, ambient UVR for 45 days. Mucus …

Factors Affecting Epithecal Growth Lines in Four Coral Species, with Paleontological Implications
… were compared for M. annularis, M. cavernosa, Porites astreoides and Tubastrea aurea. The variability among colonies from the same species was in many cases more significant than that among light treatments. This is a serious problem for anyone counting lines in corals, especially from a few …

Investigating the ecological role of sound on coral reefs
… experiments, I exposed four species of corals (Porites astreoides, Favia fragum, Diploria labyrinthiformis, and Pocillopora damicornis) to playback of reef sounds and documented their settlement responses. I found that playback of healthy reef sounds led to significant increases (~2x on average) …

SENSITIVITY AND RESILIENCE OF CNIDARIAN EARLY LIFE PROCESSES TO ANTHROPOGENIC CLIMATE CHANGE
… reef-building corals, Galaxea fascicularis and Porites astreoides. Finally, we found that exposure of adult N. vectensis to seawater acidification or hypoxia induced changes in gamete production and physiology (e.g., decreased egg production), which were correlated with modified outcomes (e.g., …

Effects ofUltraviolet Radiation on Newly Settled Recruits of the Reef-building Coral <em>Porites astreoide</em>
… adult colonies of the green color morph of <em>Porites astreoides</em> were collected from West end of Bahia Honda and the West end of 7-mile bridge and subsequently held in flow-through tanks for one year under 80% shade cloth. One year later larvae were collected from these colonies between 4 …
