“…The structure and patterns of spatial and temporal variability of macroalgal and sessile macro-invertebrate assemblages of coralligenous habitat have been widely studied (Boudouresque, 1973;Ferdeghini et al, 2000;Cocito et al, 2002;Cocito, 2004;Piazzi et al, 2004Piazzi et al, , 2010Balata et al, 2005Balata et al, , 2006Virgilio et al, 2006;Abbiati et al, 2009;Piazzi & Balata, 2011;Ponti et al, 2011). On the contrary, information about mobile macro-invertebrate assemblages of coralligenous habitat is limited to the knowledge of the species composition of several areas (Bellan, 1964;Laubier, 1966;Hong, 1980Hong, , 1982Huelin & Ros, 1984;Zabala, 1984;Martin, 1987;Jimeno & Turon, 1995;Casellato & Stefanon, 2008), while little is known about patterns of variability.…”

The study aimed to investigate patterns of spatial and temporal variability of mobile macroinvertebrate assemblages associated to coralligenous habitat. A multi-factorial sampling design was used to test the hypotheses that the structure of assemblages and their spatial and temporal variability changed in relation to substrate inclination. Moreover, macroalgae and sessile macroinvertebrates were also investigated in order to detect eventual relationships between sessile and mobile assemblages. A total of 236 mobile macro-invertebrate taxa were identified, among them 2 Platyhelminthes, 4 Sipuncula, 6 Nemertea, 27 Mollusca, 86 Annelida, 103 Arthropoda, 8 Echinodermata. The results of the study show that mobile macro-invertebrate assemblages of coralligenous habitat were little influenced by the inclination of substrate and by the morphology of sessile organisms, as patterns of variation were different between the two assemblages. Mobile macro-invertebrate assemblages changed among sampling dates within a one-year period and showed high variability at the spatial scale examined.

“…The development of monitoring programmes needs the assessment of effective sampling designs and methods in order to optimize efforts and to give appropriate responses to ecological problems. Coralligenous assemblages have been widely studied in relation to species composition (Laubier 1966, Hong 1982, Garrabou et al 2002, Casellato and Stefanon 2008, patterns of spatial and temporal variability (Ferdeghini et al 2000, Cocito et al 2002, Piazzi et al 2004, Balata et al 2005, 2006a, 2006b, Virgilio et al 2006, Ponti et al 2011, and responses to anthropogenic impacts (Hong 1983, Garrabou et al 1998, Balata et al 2007a, 2007b, Piazzi et al 2007, Roghi et al 2010. Recently, several methods have been developed to assess ecological quality of coralligenous assemblages through a non-destructive approach (Kipson et al 2011, Deter et al 2012a, Gatti et al 2012.…”

Summary:Coralligenous habitat is one of the most important and sensitive habitats of the Mediterranean Sea and several different sampling procedures are currently used in the ecological investigations of coralligenous assemblages. This study aimed to assess the efficacy of different methods in detecting anthropogenic impacts on coralligenous habitat. In particular, the choice of sampling methods, the level of taxonomic resolution, the sampling area, the number of replicates and the spatial scales for detecting possible impacts were evaluated. Results showed that photographic samples larger than 1800 cm 2 , numbers of replicates larger than 10, the use of taxa and morphological groups as assemblage descriptors, and sampling designs with a high replication at small spatial scales are a valid methodological procedure in impact evaluation studies based on coralligenous assemblages.Keywords: coralligenous habitat; sampling methods; spatial scales; number of replicates; sampling surface; Mediterranean Sea. Efectividad de los diferentes procedimientos de muestreo para detectar el impacto antrópico sobre la comunidad de coralígenoResumen: El hábitat coralígeno es uno de los más importantes y sensibles del mar Mediterráneo y actualmente se pueden aplicar varios métodos de muestreo en las investigaciones ecológicas de las comunidades macroalgales coralígenas. El objetivo del presente estudio es evaluar la efectividad de los diferentes procedimientos para detectar el impacto antrópico sobre el hábitat de coralígeno. Se evaluaron en particular la elección de los métodos de muestreo, el nivel de resolución a la que los taxones tienen que ser identificados, la superficie de muestreo, el número de repeticiones y las escalas espaciales adecuadas para la investigación de los posibles impactos. Los resultados indican que muestras fotográficas de 1800 cm 2 , un número de repeticiones mayor que 10, el uso de taxones y grupos morfológicos como descriptores y diseños de muestreo con una alta replicación asociada a pequeñas escalas espaciales pueden representar elementos metodológicos válidos en los estudios de evaluación de impacto basados en las comunidades coralígenas.Palabras clave: hábitat coralígeno; métodos de muestreo; escalas espaciales; número de repeticiones; superficie de muestreo; Mar Mediterráneo.

“…In the Mediterranean, its distribution varies widely from one area to another. E. verrucosa is well-represented in the Alboran sea and along the Moroccan and Algerian coasts (Grasshoff 1992, Claude Reveret unpublished data), but is found sporadically in the northwestern basin: in Italy and France (Provence and Côte d'Azur, western coast of Corsica) and along the Spanish coasts (Berdar and Cavallero 1980, Balduzzi et al 1992, Calvín Calvo 1995, Cocito et al 2002, Coppo et al 2009). In the northern part of the western Mediterranean, it is mainly found on the hard substrates of the lower circalittoral (35 m depth) up to the upper limit of the bathyal stage (200 m depth) (Carpine andGrasshoff 1975, Grasshoff 1992); its presence at shallower depths is rare (e.g.…”
