“…Thus, algal assemblages at a given depth and on the same type of substrate are homogeneous (personal observation). Further support for the hypothesis of a possible negative effect of A. taxiformis on the native assemblage is suggested by the decrease of between 5 to 7 species in this study when compared to the catalogue of flora described by Cebrián & Ballesteros (2004) at the same bathymetric range (8-10 m) when A. taxiformis was absent.…”

“…Spatial differences between assemblages can be ruled out as affecting the obtained results, because sampling was conducted in areas within the same bathymetric range and on identical types of substrate. Depth is the most important factor affecting community composition in Marina del Este (Cebrián & Ballesteros, 2004). Thus, algal assemblages at a given depth and on the same type of substrate are homogeneous (personal observation).…”

Structure and temporal dynamics of a seaweed assemblage dominated by the invasive lineage 2 of Asparagopsis taxiformis (Bonnemaisoniaceae, Rhodophyta) AbstractAsparagopsis taxiformis is a rhodophycean species composed of six genetic lineages, one of which is considered a relevant invasive component of Mediterranean flora. This study describes seasonal changes in the structure and biomass of the native community associated with A. taxiformis on the coast of Granada (southern Spain). The native community was represented by 18 Rhodophyta, 3 Chlorophyta, and 4 Ochrophyta species. Biomass was dominated by A. taxiformis and Halopteris filicina. In January, A. taxiformis represented only 16% of the whole community biomass, but 2 months later, more than 90% of the community biomass was formed by the invasive species. During the study period, species richness, the Shannon diversity index, and species evenness showed low and generally stable values. Given that A. taxiformis gametophytes are present throughout the year, they likely pose a constant stress to the development of the native community. This survey provides baseline information on the macroalgal community structure, which may be useful to further studies on the actual impact of the invasive lineage of A. taxiformis

“…Factors such as seawater temperature and wave action might be a seasonal reason for the ver tical distribution of associated macrofauna (Neto 2000). In fact at 0 m, hydrodynamism is greater due to strong wave action, whereas at deeper sites the impact of this factor is greatly reduced, as demonstrated by Cebrián & Ballesteros (2004) in the same area. It has been pointed out that wave action affects patterns of distribution in the associated macrofauna in the intertidal zone (Chavanich & Wilson 2000).…”

“…We chose a site with a rocky substrate with similar coverage of Astroides calycularis (between 50 and 75% cover) at the 3 depths. Cebrián & Ballesteros (2004) de scribed the zonation of the rocky benthic communities in this area, and concluded that depth was the main axis of variation. These authors observed differences among communities between lower depths (25 m) and the shallow infralittoral zone (5 m).…”

The orange coral Astroides calycularis is internationally protected due to its narrow distribution, its sensitivity to environmental changes and anthropogenic disturbance. Spatio-temporal macrofaunal assemblages associated with A. calycularis were studied along the southern coast of the Iberian Peninsula. A total of 878 invertebrate specimens were collected, comprising 81 species. At the 3 depths studied (0, 5 and 10 m), crustacean species were dominant in terms of abundance, followed by annelids and molluscs. Macrofaunal densities were higher in October and May, and lower in August and September. Janira maculosa (isopod), Lembos spp. (gammarid) and Stenothoe cavimana (gammarid) were the most abundant species, present in almost all depths and months. ANOVA analyses by month reflected significant differences in species richness and Shannon-Wiener diversity, but no differences among depth ranges and no interaction between time and depth. PERMANOVA analyses showed significant differences in the associated macrofauna for time and depth, but no interaction was observed between these factors. These results indicate the ecological relevance of this Mediterranean scleractinian coral as a habitat for many macrofaunal groups. Furthermore, the conservation of this endangered species contributes to the preservation of high marine biodiversity.

“…This concept was subsequently adapted to Mediterranean benthic communities (Boudouresque 1984, and it was recently revised and updated by Morri et al (2004). The adscription of different assemblages followed the existing literature for the region (Carpine 1970, Guille 1971, Desbruyères et al 1972/73, Gili et al 1987, as well as previous bionomic papers Ros 1985, Cebrian andBallesteros 2004), and was adapted to the description list of Natura 2000 and EUNIS for the purpose of facilitating conservation information management.…”

SUMMARY:The marine benthic cartography of the Cap de Creus and surrounding areas (NW Mediterranean Sea) was obtained by combining classical grabbing methods with more recent imaging methods based on a remotely operated vehicle. The goals of this particular survey can be summarized as follows: 1) to chart the benthic communities (and the area of each one); 2) to evaluate the benthic diversity of the areas; 3) to produce visual documentation of the distributions of the benthic organisms; 4) to identify human-induced pressures on the benthic environment; 5) to make recommendations for future management based on the visual assessment; and 6) to set up a new methodology for making large biocenosis maps that would help to manage marine protected and non-protected areas. The marine environment off the Alt Empordà County was shown to have a very rich diversity of benthic habitats. Twenty community categories were identified from videos and grabs. Though benthic habitats mostly located inside a marine protected area were assessed, man-made objects were seen in 10% of the analyzed minutes filmed. The study led to a comprehensive review of the main biotope systems of this coastal area, as well as their environmental condition, and this will be an essential element for their future management.Keywords: benthic cartography, ROV, marine protected areas, NE catalan coast. RESUMEN: Cartografía bentónica marina del Cabo de Creus (costa catalana NE, Mar Mediterráneo). -Se presenta una cartografía bentónica marina del Cabo de Creus y sus áreas adyacentes (NO del Mediterráneo). Esta cartografía ha sido obtenida combinando métodos clásicos de dragado con métodos basados en imágenes obtenidas mediante vehículos operados a control remoto (ROV). Los objetivos de este estudio pueden resumirse en: 1) efectuar un mapa de sus comunidades (y su extensión), 2) evaluar su diversidad de hábitats, 3) documentar visualmente la distribución de sus organismos, 4) identificar presiones humanas en el medio marino, 5) efectuar recomendaciones para su futura gestión, y 6) desarrollar una nueva metodología de generación de mapas que pueda servir en la gestión de áreas marinas protegidas y no protegidas. El ambiente estudiado se caracteriza por una alta diversidad de hábitats, una veintena fueron identificados. A pesar de estar trabajando principalmente en una zona protegida, en el 10% de los minutos de filmación se observaron objetos de procedencia humana. Este trabajo ha servido para evaluar los sistemas naturales presentes así como su estado de salud y se espera que los resultados obtenidos puedan ser usados para una futura gestión de esta zona costera.Palabras clave: cartografía bentónica, ROV, áreas marinas protegidas, NE costa catalana.
