“…11,14) In Costa Rica and Panama, blooms of Cochlodinium catenatum were implicated in coral mortality, which was partly attributed to smothering by the mucus produced by the dinoflagellate. 31) Consistently with these reports, our previous studies indicate that polysaccharides gradually accumulated in the medium of C. polykrikoides during culture, and the amount of polysaccharides was much greater than that of C. marina.…”

“…The region has suffered the consequences of warming events in 1982/1983/1998(Glynn et al 1988) and, to a lesser extent, of red tides (Guzman et al 1990). The 1982/1983 mortality apparently affected Table 2. reefs regardless of whether they were to windward or leeward of the islands, and whether they were close or far from continental influence (Glynn 1984).…”

Distribution, diversity, and conservation of coral reefs and coral communities in the largest marine protected area of Pacific Panama (Coiba Island)

SUMMARYSampling scale and lack of attention to taxa other than scleractinian corals have limited the capacity to protect coral reefs and coral communities in Pacific Panama. The distribution of coral habitats (live coral cover) and their species richness in the largest marine protected area of Panama, the Coiba National Park (270 125 ha), is described using quadrat transects and manta tows. The species richness of scleractinian corals and octocorals was lower in coral reefs than in coral communities, and a close relationship between richness and live coral cover was observed only in coral communities. The distribution of high live coral cover in coral communities overlapped with areas of high coral species richness. Average live coral cover in communities was 64%, compared to 28% in reefs, whereas algae cover was 30% and 49%, respectively. Twenty-two coral and 34 octocoral species were observed, many only now detected in Panama as endemic or new species. Analysis of satellite imagery showed 80% of terrestrial habitats were mostly primary forest, and coral reefs and coral communities covered 1700 ha, about 2% of marine habitats. Shallow marine environments (<20 m) had up to 60% calcareous red algae cover (rhodolite beds). Based on the distribution of live coral cover and species richness, three conservation units were identified as priority, with the southern and northernmost sides of the marine protected area as the most significant. These three areas encompass most of the rare and endemic species or populations, as well as species previously regarded as endangered.

“…Planktonic harmful algal blooms in coral reef waters sometimes occur, but have seldom been documented (Guzman et al 1990). Therefore, the consequences of an increased nutrient load of human origin on the phytoplankton community structure need to be considered in various coral reef environments of differing trophic status.…”

We investigated the effects of changes in nutrient concentrations on phytoplankton biomass and community composition during 8 field trips performed during different seasons in the southwestern coral lagoon of New Caledonia. The lagoon is characterized by spatial variation in macronutrient concentrations, with locally elevated values in the bays bordering the city of Nouméa. Low DIN:DIP (dissolved inorganic nitrogen:dissolved inorganic phosphorus) and elevated Si:DIN ratios suggest that nitrogen is the macronutrient that likely drives phytoplankton community composition. Most of the microphytoplankton groups discriminated by inverted microscopy and the picoplankton groups distinguished by flow cytometry present significant and distinct relationships with inorganic nitrogen concentrations. Picophytoplankton-dominated assemblages are replaced by microphytoplankton-dominated assemblages with increasing DIN concentrations. Within the picophytoplankton, Prochlorococcus abundance dominates in the adjacent oceanic and southern lagoon shelf sites, and assemblages shift to Synechococcus-dominated populations in the bays, with an increasing proportion of picoeukaryotic phytoplankton. Within the microplankton, 142 species of microphytoplankton were identified, mainly represented by diatoms, dinoflagellates, and coccolithophorids. Nutrient enrichment in the bays favors large diatoms at the expense of coccolithophorids and dinoflagellates, which dominate in adjacent oceanic and southern shelf waters. Therefore, although moderate, the elevated nitrogen concentrations in the bays result in increased phytoplankton biomass, accompanied by important shifts in the phytoplankton community structure.
