The reef coral two compartment proton flux model: a new approach relating tissue-level physiological processes to gross corallum morphology.
The first includes 86 samples for whole-rock [[delta].sup.13][C.sub.carb] and [[delta].sup.18]Ocarb analyses, 23 brachiopod shell samples and 12 samples from rugose corals (mainly the proximal part of a conical corallum, all from the same levels where whole-rock analyses are made).
The morphological variation in tabulate corals occurs at different levels: within the corallum, within the population, and between populations (Dixon 1989; Webb 1996).
Diagnosis: El corallum es de forma arqueada (convexa) y gruesa, cuyo margen es discoidal y ligeramente ovalado.
Corallum morphology and composition of crustacean cryptofauna of the hermatypic coral Madracis mirabilis.
Variations in corallum morphology, host physiology, and the genotypes of Symbiodinium represent proximal mechanisms used by corals, with the ultimate effect of stabilizing the symbiosis in the face of environmental challenges (Loya et al., 2001: Jones et al., 2008; Baird et al., 2009; Logan et al., 2014).
The colonies have a coiled corallum composed of a variable number of turns.
Several longitudinal and transverse sections were made from each tabulate corallum. Coral endosyrnbionts were searched under a binocular light microscope.
The mass-transfer consequences of corallum shape under different flow regimes (Patterson, 1992) offers a promising theoretical framework to better understand why massive Porites spp.
It can be easily recognized by the bulbous or spherical shape of the corallum. Due to the simple morphology of internal characters like the polygonal corallites, pores predominantly located in corners, variable thickness of corallite wall and septal development, and by the similar size of corallites, this species is easily confused with P.
The basic structure of the coral polyp is a tubelike skeleton, or corallum, divided by longitudinal and horizontal partitions.
