Diversity, distribution and population size structure of deep Mediterranean gorgonian assemblages (Menorca Channel, Western Mediterranean Sea)
2016, Progress in OceanographyCitation Excerpt :Such stability in the main environmental conditions could allow deep gorgonians to grow larger and develop populations dominated by medium and large-sized colonies (Grigg, 1975; Watanabe et al., 2009; Gori et al., 2011b). Toppling and detachment by strong currents or wave action is considered one of the main causes of mortality of large gorgonian colonies (Grigg, 1977; Weinbauer and Velimirov, 1996; Weinberg and Weinberg, 1979). Indeed, both the environmental suitability and stability of a habitat may be reflected in the size structure of gorgonian and coral populations, because the size structure reflects the factors affecting recruitment, growth, and mortality rates in a particular habitat for a period of time matching the longevity of the population (Grigg, 1975; Gilmour, 2004; Alvarado-Chacón and Acosta, 2009).
Fishing impact on deep Mediterranean rocky habitats as revealed by ROV investigation
2014, Biological ConservationCitation Excerpt :Coral abundance can be used to compare sites only if their depth ranges, hence the communities they host, are similar. Of our four study cases, the Mantice Shoal represents an outsider, being dominated by shallow water species which commonly form extended and dense assemblages (Linares et al., 2007; Weinbauer and Velimirov, 1996). The Mantice Shoal can be compared with the almost pristine summit coral assemblages of the Vercelli Seamount where the total coral abundance was about six times higher, even though they host the same species of gorgonians at the same depth range (Bo et al., 2011a).
Structure, growth and secondary production of two Tyrrhenian populations of the white gorgonian Eunicella singularis (Esper 1791)
2013, Estuarine, Coastal and Shelf ScienceCitation Excerpt :The intensity of water current was quite different at our two study sites (Cannitello >4 knots; Enfola <2 knots; Magazzù, 1989). Strong currents represent one of the most important cause of mortality in large octocorals, causing colony detachment or toppling (Weinbauer and Velimirov, 1996). Up to a certain size, colonies can withstand strong water movement, but whenever this size is exceeded, very strong currents may detach them (Grigg, 1977).
