Red coral (Corallium rubrum, L. 1758) is an over-exploited Mediterranean gorgonian. The gonadal development cycle of this gorgonian is examined at the Costa Brava (NW Mediterranean) taking into account for the first time colony size, depth and spatial horizontal variability. This study compares the gonad development and fertility in two colony size classes (colonies <6-cm height, and >10-cm height, both at 40–45-m depth), and two populations at different depths (16–18-m depth, and 40–45-m depth… 
Seasonal cycle of sexual reproduction of the Mediterranean soft coral Alcyonium acaule (Anthozoa, Octocorallia)
TLDR
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.
Demographic parameters of two populations of red coral (Corallium rubrum L. 1758) in the North Western Mediterranean
TLDR
Despite similar growth and fecundity, the two populations showed different densities and size/age structures suggesting local factors, together with different fishing pressures, have to be taken into account in the management plans for this species.
Fecundity of red coral Corallium rubrum (L.) populations inhabiting in contrasting environmental conditions in the NW Mediterranean
TLDR
The variability and potential patterns of fecundity in the precious Mediterranean red coral Corallium rubrum varied significantly for populations dwelling in different cave zones and geographic areas but not for the examined depths.
Reproductive features and gonad development cycle of the soft bottom-gravel gorgonian Leptogorgia sarmentosa (Esper, 1791) in the NW Mediterranean Sea
TLDR
Leptogorgia sarmentosa appeared to have a different reproductive strategy to other Mediterranean gorgonians (living on hard bottom substrata), probably because of its different habitat preferences and biological features.
Reproductive patterns in deep versus shallow populations of the precious Mediterranean gorgonian Corallium rubrum (Linnaeus, 1758) (Sardinia, central-western Mediterranean)
TLDR
Differences in reproductive parameters such as sexual products distribution and reproductive output (fecundity) were observed between shallow and deep populations of C. rubrum, in particular within deep dwelling populations.
Temporal and spatial variation in protein, carbohydrate, and lipid levels in Corallium rubrum (Anthozoa, Octocorallia)
TLDR
The biochemical levels prove to be a useful tool to detect unusual environmental conditions that may cause partial or total mortality in benthic suspension feeders, especially in the shallow population of red coral.
Population structure of an exploited benthic cnidarian: the case study of red coral (Corallium rubrum L.)
TLDR
This study found that some harvested red coral populations had a significantly different size structure when compared to populations at the nearby Marine Protected Area of Medas Islands at the Spanish Costa Brava (NW Mediterranean), confirming that MPAs are useful to distinguish between anthropogenic and natural influences on population structure.

Reproduction and population sexual structure of the overexploited Mediterranean red coral Corallium rubrum
TLDR
This study provides the first description of the reproductive features of a red coral Coral- lium rubrum population that has been over-harvested and stocks are depleted and shows large differences in larval production between populations with different size and/or age structures.
Demography, Reproductive Biology and Trophic Ecology of Red Coral (Corallium rubrum L.) at the Costa Brava (NW Mediterranean): Ecological Data as a Tool for Management
TLDR
It is found that the population structure of harvested red coral populations had a significantly different size structure when compared to populations at the nearby Marine Protected Area of Medas Islands at the Spanish Costa Brava (NW Mediterranean), and the demography of a population is a useful indicator for its state, especially for longevous sessile species.
Demography of the over-exploited Mediterranean red coral (Corallium rubrum L. 1758)*
TLDR
The ratio of larval survival to adult density found indicates that some density-dependent limitation of population growth is likely at play in the population under study, and will be important for understanding dynamics of red coral disturbed or exploited populations.
LIFE HISTORY STUDIES ON THE RED SEA SOFT CORAL XENIA MACROSPICULATA GOHAR, 1940. I. ANNUAL DYNAMICS OF GONADAL DEVELOPMENT
TLDR
Xenia macrospiculata Gohar, 1940 is a dominant xeniid species on the coral reefs of the Gulf of Eilat and the population contains colonies in various stages of development.
Settlement and recruitment: The first stages in the life cycle of two epibenthic suspension feeders (Corallium rubrum and Anomia ephippium)
TLDR
This study provides a detailed analysis of the settlement and recruitment processes in a red coral coastal population of the Eastern Ligurian Sea and provides basic knowledge on the early phases of the red coral life cycle.
Settlement and early survival of red coral on artificial substrates in different geographic areas: some clues for demography and restoration
TLDR
A significant variability between different sites at a few hundred metres distance occurred, indicating high variations in the recruitment process within the same red coral population, indicated by a 2-factors nested ANOVA.
Red coral: conservation and management of an over-exploited Mediterranean species
TLDR
Development of a regime for the sustainable exploitation of this species requires a better knowledge of population dynamics, life-history traits and quantitative genetics, especially concerning commercial populations.
Reproduction and cycle of gonadal development in the Mediterranean gorgonian Paramuricea clavata
TLDR
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.

TLDR
Data suggest that high colony fecundity, achieved after a long growth period as an immature colony, and an abrupt decrease of colony growth rate after maturation are the crucial forces for the evolution of delayed maturation.
