This study examined the sexual reproductive cycle, energy storage and metabolic requirements of a Mediterranean gorgonian in a mesophotic ecosystem (~70 m depth). Paramuricea macrospina resulted to be a gonochoric internal brooding species with a 1:1 population sex ratio. Oogenesis lasted ~12–14 months, whereas spermatogenesis was significantly shorter, only lasting 6 months. Fertilization occurred during late summer (August) and larval release occurred during autumn (September–October). The… 
Seasonal variation in the lipidome of two species of Millepora hydrocorals from Vietnam coastal waters (the South China Sea)
Data on seasonal variations of the lipidomes provide new background information for future studies of ecology, physiology, and biochemistry of hydrocorals.
Annual Dynamics of the Composition of Polar Lipids, Storage Lipids, and Fatty Acid Markers in the Hydrocoral Millepora dichotoma Forskål, 1775 from Coastal Waters of Vietnam
Abstract The amount of structural and storage lipids and the composition of fatty acids (FA) in the symbiotic hydroid coral Millepora dichotoma were determined monthly throughout the year. In the
Temperate mesophotic ecosystems: gaps and perspectives of an emerging conservation challenge for the Mediterranean Sea
Abstract Mesophotic habitats, hosting benthic assemblages totally unknown and unexpected in the early 2000s, are attracting an increasing interest from scientists. Realizing that many long living and
Shallow-emerged coral may warn of deep-sea coral response to thermal stress
It is shown that sperm from deep colonies develops completely, but in shallow colonies, sperm development is prematurely halted, likely preventing successful production of larvae, and hypothesize that the divergence is due to differing temperature regimes presently experienced by the corals.


Variation in lipid and free fatty acid content during spawning in two temperate octocorals with different reproductive strategies: surface versus internal brooder
Investigating the energetic investment during spawning of two Mediterranean gorgonians characterized by different reproductive strategies suggested that the majority of the energetic cost was due to reproductive activity, with P. clavata investing more energy in reproduction than C. rubrum.

A population of the coral Pocillopora damicornis was examined for 12 months to investigate whether different reproductive activities in the corals affected patcerns of energy allocation, demonstrating a substantial cost of reproduction since corals which did not produce brooded larvae and ova put more resources into grwoth and storage of lipid.
Reproduction and cycle of gonadal development in the Mediterranean gorgonian Paramuricea clavata
The reproductive biology of this species was studied from 1990 to 1992 off the Medes Islands and spawned eggs adhered, through the action of a mucous coating, to the outer surfaces of the female colonies.
Reproductive cycle and trophic ecology in deep versus shallow populations of the Mediterranean gorgonian Eunicella singularis (Cap de Creus, northwestern Mediterranean Sea)
The annual gonad development of a shallow (20 m depth) population of the Mediterranean gorgonian Eunicella singularis was found to be closely synchronized with that of a deep (60 m depth) population,
Cycle of gonadal development in Eunicella singularis (Cnidaria: Octocorallia): trends in sexual reproduction in gorgonians
The patterns emerging from this and previous studies on sexual reproduction of Mediterranean gorgonians suggest that investment in gonad development appears to be related to resource availability.
Seasonal cycle of sexual reproduction of the Mediterranean soft coral Alcyonium acaule (Anthozoa, Octocorallia)
Sexual reproduction and the gamete development cycle of this soft coral are described and the data suggest that the relatively constant temperatures in January–April are probably not related to oocyte maturation, but that rising temperatures in May could affect sperm maturation.
Effect of seawater temperature on reproductive seasonality and fecundity of Pseudoplexaura porosa (Cnidaria: Octocorallia): latitudinal variation in Caribbean gorgonian reproduction
The shorter reproductive season in Bermuda, in addition to the lower fecundity of colonies, indicates that reproduction in P. porosa is compromised at this high latitude reef.
Reproduction, abundance and survivorship of two Alveopora spp. in the mesophotic reefs of Eilat, Red Sea
Reports for the first time on the reproductive patterns, living cover, and survivorship under different light treatments of two scleractinian species from the MCEs of Eilat, Red-Sea: Alveopora allingi and A. ocellata, which display a synchronous gametogenic cycles with consecutive oocyte growth and development.
Temporal variation in protein, carbohydrate, and lipid concentrations in Paramuricea clavata (Anthozoa, Octocorallia): evidence for summer–autumn feeding constraints
It is shown that protein, carbohydrate, and lipid levels may provide a record of episodes in the ecological cycle bearing on the trophic aspects of the target species, provided factors such as natural diet, feeding rates, reproduction, and growth are well understood.
