“…The results of this paper also showed that, although both the ESCA and ESCA-A indices, when used alone, clearly separated the highly urbanized locations from the other ones, the ESCA-TA index detected more finely the three environmental conditions, also revealing those subtle differences between locations under a regime of protection and locations affected by low levels of urbanization. The higher degree of correlation between ESCA-TA and ESCA suggests a higher sensitivity of macroalgae, compared with macro-invertebrates, to those environmental alterations that usually occur in the urbanized areas, such as the increase in nutrients and water turbidity (Lopez y Royo et al 2009). By contrast, sessile animals can be more sensitive than macroalgae to other kinds of stress, such as effects of climate changes and mechanical disturbances due to fishing, recreational diving and anchoring (Cerrano et al 2000, Coma et al 2006, de la Nuez-Hernández et al 2014.…”

“…The level of urbanization for each location was determined according to the presence of local pressures (e.g. industries, ports and rivers) and the distance of the studied locations from these sources of pressure (Lopez y Royo et al 2009, Piazzi et al 2015. Although pristine ecosystems in the Mediterranean Sea can no longer be expected (Jackson andSala 2001, Stachowitsch 2003) and the boundaries of MPAs do not protect them from the effects of global impacts such as climate change and water turbidity (Montefalcone et al 2009, Parravicini et al 2013, Mateos-Molina et al 2015, the five locations selected within MPAs are characterized by low levels of urbanization and are protected from impacts related to human activities such as fishing and anchoring.…”

Summary:The ESCA (Ecological Status of Coralligenous Assemblages) index was developed to assess the ecological quality of coralligenous habitat using macroalgae as a biological indicator. The aim of this study was to evaluate the response to human-induced pressures of macroalgae and sessile macro-invertebrates shaping the coralligenous habitat and to integrate their sensitivity into the ESCA index. Coralligenous assemblages were sampled at 15 locations of the NW Mediterranean Sea classified into three groups: i) marine protected areas; ii) low urbanized locations; and iii) highly urbanized locations.A sensitivity level value was assigned to each taxon/group on the basis of its abundance in each environmental condition, the data available in the literature and the results of an expert judgement survey. The index that includes the totality of the assemblages (named ESCA-TA), calculated using both macroalgae and sessile macro-invertebrates, detected the levels of human pressure more precisely than the index calculated with only macroalgae or with only invertebrates. The potential for assessing the ecological quality of marine coastal areas was thus increased with the ESCA-TA index thanks to the use of a higher variety of descriptors.Keywords: coralligenous assemblages; ESCA and ESCA-TA indices; ecological quality; macroalgae; macro-invertebrates; Mediterranean Sea. Integración de el índice ESCA por medio de los macro-invertebrados sésilesResumen: El índice ESCA (Estado Ecológico de las Comunidades Coralígenas) ha sido desarrollado para determinar el estado ecológico de los hábitats coralígenos utilizando macro-algas como indicador biológico. El objetivo de este estudio fue evaluar la respuesta, ante presiones antropogénicas, de macro-algas y macro-invertebrados sésiles moldeadores de la comunidad coralígena y su sensibilidad al índice ESCA. Se muestrearon comunidades coralígenas en 15 localizaciones del Mediterráneo Nord-Occidental clasificadas en 3 grupos: i) áreas marinas protegidas; ii) poco urbanizadas; iii) muy urbanizadas. Un valor de Nivel de Sensibilidad fue asignado a cada taxón/grupo en base a su abundancia en cada condición medioambiental, a información bibliográfica disponible y a los resultados de juicios por parte de expertos. El índice que integra la totalidad de las comunidades (llamado ESCA-TA), calculado usando tanto macro-algas como macro-invertebrados sésiles, detectó los diferentes niveles de presión humana de manera más precisa que el índice calculado solo con macro-algas o solo con invertebrados. El potencial para determinar el estado ecológico de las áreas marinas protegidas se incrementó con el índice ESCA-TA gracias al uso de una mayor variedad de descriptores.Palabras clave: comunidades coralígenas; índices ESCA y ESCA-TA; estado ecológico; macro-algas; macro-invertebrados; mar Mediterráneo.

“…Five variables, including agricultural land use (AGR), forest land use (FOR), population density (POP), urbanization (URB), and per capita gross domestic product (ECO) were finally selected based on data availability and their known influence on river health (Stern et al, 1996;Wang et al, 2008;Kanno et al, 2010). A principal component analysis (PCA) (Magalhães et al, 2008;Lopez et al, 2009) was run on all sampling sites based on the above variables. The type of correlation (positive or negative) for the factors loading of the variables and sampling sites scores on PC axes were used to assess the pressure overall.…”

“…Method validation should ideally include (1) testing the index using an independent data set, (2) identifying reference and stressed sites in the validation dataset using the same physiochemical criteria (Astin, 2007;Borja and Dauer, 2008). Therefore, a quantitative assessment based on governmental census data, which has been proven to be a reliable and cost-efficiency tool for assessing of human-induced pressures on the aquatic ecosystem (Lopez et al, 2009), was used to validate our method. All sites but XF had the same results with the both methods.…”

“…The inner continental shelf has a particular importance in the framework of coastal management, as it represents the boundary between the coastal zone, usually highly influenced by human activities, and the open ocean (Royo, Silvestri, Pergent, & Casazza, 2009). For this reason, the inner shelf is considered that part of the marine environment most prone to human-induced alterations and impacts, and is the zone where the greatest conservation and management efforts are usually directed .…”

In this paper, we present a map describing the main geomorphological features of the coastal and marine area between the towns of Albenga and Savona (Ligurian Sea, NW Mediterranean) corresponding to a coastal stretch of 40 km. To produce this map, we collated data from the literature, orthophotos, perspective photos, multibeam and side scan sonar data, and undertook direct surveys to ground truth data obtained using indirect techniques. We divided the information into nine thematic layers, including bathymetry, natural coastal types, geomorphological elements, seafloor coverage (both geological and biological), coastal and nearshore dynamics, human influence on coastal and marine environments, coastal occupation and protected areas.
