We identified 11 distinct areas that fit the definition of "ecosystems," which is enduring regions demarcated by environmental characteristics. Overall, the "ecosystems" retained their general distribution with latitude boundaries in each season, while there were some variations in latitude and some ...
Furthermore, the few coral species that span the depth distribution from upper-mesophotic waters (30–40 m) down to the lower mesophotic zone (60–70, and 80–90 m for Leptoseris spp.) experienced more severe bleaching in terms of prevalence and severity at mesophotic depths, with ...
Here, we provide the first in-depth assessment of a lower meso- photic coral community (60–100 m) in the Southern Caribbean to answer the following questions: (1) Does the lower mesophotic zone represent a specialized community of corals and associated Symbiodinium? (2) Does the temperature...

(all other morphs together comprised 1.6% of the surveyed population). The spectral analysis of the excitation and emission peaks of the collected corals provided a better definition of the different morphs (Fig.1). Emission peaks (for excitation at 450 nm) had been previously recorded for ...
Photic zone, surface layer of the ocean that receives sunlight. The uppermost 80 m (260 feet) or more of the ocean, which is sufficiently illuminated to permit photosynthesis by phytoplankton and plants, is called the euphotic zone. Sunlight insufficient
