Fertilization of branching Acropora

Acropora is one of the largest taxonomic groups of scleractinian corals in the Indo-Pacific and contributes towards the establishment of coral communities in the Ryukyu Islands. Branching Acropora populations have a component of asexual reproduction; however, this may lead to a decline in genetic diversity, leaving populations vulnerable to environmental changes. Therefore, a sufficient supply of larvae produced via sexual reproduction is necessary to maintain genetic diversity in the branching Acropora communities. Fertilization success in branching Acropora depends on a variety of factors, including genetic and environmental conditions. How genotype and/or genetic compatibility drives fertilization rates in Acropora communities under natural conditions has not been investigated. To investigate how genotype and/or genetic compatibility determine fertilization rates in Acropora communities over the long-term, cross-mating experiments with branching Acropora using the same colonies were conducted from 2006 to 2011 in an aquarium. Acropora from cultured and natural colonies collected from a reef (26° 40' 19.2'' N, 127° 52' 40.8'' E) were used. Fertilization rates showed less variation within the same crossing combinations, but large variation across years for the same genotypes of focal colonies. Results indicated that fertilization rate was highly variable depending on genotype compatibility with different mating partners. Additionally, simulations of fertilization rates with increasing population size revealed that small populations that had low genetic diversity (fewer than 10 genotypes) failed to fertilize. These results support the establishment or maintenance of source populations that facilitate sufficient genetic diversity of branching Acropora to enhance coral community restoration.

The 2.2 A crystal structure of a pocilloporin pigment reveals a nonplanar chromophore conformation

Reef-building corals contain host pigments, termed pocilloporins, that function to regulate the light environment of their resident microalgae by acting as a photoprotectant in excessive sunlight. We have determined the crystal structure of an intensely blue, non-fluorescent pocilloporin to 2.2 Angstrom resolution and a genetically engineered fluorescent variant to 2.4 Angstrom resolution. The pocilloporin chromophore structure adopts a markedly different conformation in comparison with the DsRed chromophore, despite the chromophore sequences (Gin-Tyr-Gly) being identical; the tyrosine ring of the pocilloporin chromophore is noncoplanar and in the trans configuration. Furthermore, the fluorescent variant adopted a noncoplanar chromophore conformation. The data presented here demonstrates that the conformation of the chromophore is highly dependent on its immediate environment.

Variation in Coral Photosynthesis, Respiration and Growth Characteristics in Contrasting Light Microhabitats: An Analogue to Plants in Forest Gaps and Understoreys?

1. The often complex architecture of coral reefs forms a diversity of light microhabitats. Analogous to patterns in forest plants, light variation may drive strategies for efficient light utilization and metabolism in corals. 2. We investigated the spatial distribution of light regimes in a spur-and-groove reef environment and examine the photophysiology of the coral Montipora monasteriata (Forskal 1775), a species with a wide habitat distribution. Specifically, we examined the variation in tissue and skeletal thickness, and photosynthetic and metabolic responses among contrasting light microhabitats. 3. Daily irradiances reaching corals in caves and under overhangs were 1-5 and 30-40% of those in open habitats at similar depth (3-5 m), respectively. Daily rates of net photosynthesis of corals in cave habitats approximated zero, suggesting more than two orders of magnitude variation in scope for growth across habitats. 4. Three mechanisms of photoadaptation or acclimation were observed in cave and overhang habitats: (1) a 20-50% thinner tissue layer and 40-60% thinner skeletal plates, maximizing light interception per unit mass; (2) a two- to threefold higher photosynthetic efficiency per unit biomass; and (3) low rates of dark respiration. 5. Specimens from open and cave habitats displayed a high capacity to acclimate to downshifts or upshifts in irradiance, respectively. However, specimens in caves displayed limited acclimation to further irradiance reduction, indicating that these live near their irradiance limit. 6. Analogous to patterns for some plant species in forest gaps, the morphological plasticity and physiological flexibility of M. monasteriata enable it to occupy light habitats that vary by more than two orders of magnitude.
