RT info:eu-repo/semantics/masterThesis T1 Reproduction capacity of the white gorgonian Eunicella singularis after restoration of colonies sourced from bycatch A1 Edery Jiménez, Gal·la A2 Máster Universitario en Biología Marina: Biodiversidad y Conservación AB In the WE Mediterranean sublitoral communities, gorgonian species play an important role as ecosystem engineers, which are protected by the European Union. However, artisanal fisheries are causing damage to gorgonian populations as they get entangled on nets. Ecological restoration is a trending technic nowadays and its one of the goals included on the Sustainable Development Goals. Several studies have reported survival and growth success in corals restoration, but few is known about the effects in reproduction, needed for a long-term viability of the population. In this study, the reproduction capacity of Eunicella singularis has been tested, one, two, and three years after being sourced from the Cap de Creus artisanal fisheries bycatch and transplanted. Three different colony sizes (small, medium, and large) were also tested, as has been seen as an important factor in reproduction. Diameter of sexual products, number and volume per polyp had been measured to estimate the reproductive capacity. Results suggest that transplantation cause a reduction in the reproduction capacity on E. singularis colonies, with higher effect on males, contrary to what has been seen previously. Despite the loss of colonies produced, smaller females show better reproductive capacity than males, which has been observed in large colonies. Moreover, colonies appear not to recover during the study period, what suggest that transplantation could lead to the complete mortality of transplants over time. An unexpected algal bloom occurs during the experiment and has been suggested to also cause a sublethal effect, changing oogenesis timing and reducing the reproduction capacity of both sexes, creating a synergy with transplantation.
