| By altering the phenotypic properties of their hosts, endolithic parasites can modulate the engineering processes of marine ecosystem engineers. Here, we assessed the biogeographical patterns of species assemblages, prevalence and impact of endolithic parasitism in two mussel species that act as important ecosystem engineers in the southern African intertidal habitat, Perna perna and Mytilus galloprovincialis. We conducted large-scale surveys across three biogeographic regions along the South African coast: the subtropical east coast, dominated by the indigenous mussel, P. perna, the warm temperate south coast, where this species coexists with the invasive Mediterranean mussel, M. galloprovincialis, and the cool temperate west coast dominated by M.... |

| During six consecutive months, sampling were made at three points located on Governador Island and three on Paquetá Island in Guanabara Bay, Rio de Janeiro, Brazil. Material was collected from dock pilings and rocks in the intertidal zone. In these samples, five species belonging to three families, Corynidae, Kirchenpaueriidae and Campanulariidae, were identified. The campanulariid species Obelia dichotoma Linnaeus, 1758, dominated at nearly all points sampled. The small number of species obtained in this survey is attributed to the intense pollution in the bay, which borders the second-largest industrial complex and the second-largest demographic center of Brazil. |

| Here we investigate spatial variation in shell shape of Littorina saxatilis, an ovoviviparous species, and Melarhaphe neritoides, a species with planktonic eggs and larvae. Populations of both species were sampled in 6 sites located along the west coast of the Iberian Peninsula. Shell shape was studied using landmarkbased morphometric methods. Landmark data was used to estimate individual size and to describe shell shape. Prior to statistical analysis specimens were aligned using Generalised Procrustes Analysis (GPA). Ordinations based on GPA of landmark data and using Principal Components Analysis (PCA), revealed a clear spatial segregation of sites for both species, although this was more evident for L. saxatilis than M. neritoides. Statistical analysis... |

| Con el fin de colectar octocorales telestáceos y penatuláceos se revisaron diferentes ecosistemas entre O y 30 m de profundidad, mediante buceo SCUBA y simple a pulmón que comprendían litorales rocosos, fondos arenosos y arrecifes coralinos, en un área que incluye a Cartagena, las Islas del Rosario, Tierra Bomba, Barú y San Bernardo, los bancos de Salmedina y Bushnell, las ensenadas de Zapzurro y Capurganá (8°20'-10°45' N; 75°50'-77025' W), en la región de Santa Marta (11°14'50" N; 74°15' W) y la Guajira (11°56'58" N; 72°16'18" W), en el Caribe colombiano. Se encontró por primera vez en el mar Caribe y la costa colombiana a Sfy/afu/a diadema Bayer (Virgulariidae: Pennatulacea) que se halló solamente en fondos arenosos blandos entre 25 y 30 m a la salida de... |

| Thanks to this psychological study, stretched over a period of four years (1968-1972) on the algae population of the Le Dramont rocky coasts, we had the possibility to distinguish 19 different groups. Their apportionment and floristic composition have been consciously observed and studied, in summer as well as during spring, and this up to a depth of 45 m. A high number (35) of sections were done for that purpose, all over the work territory. Some of them are reproduced here (fig. 1, 2, 3, 4), with an indication of the placement of the different groups. Next, we compared our results with those of previous works, and we were able to conclude that the studied area is very analogue to the one of the J. Feldman study of the Albères Coast. |

| Wave height was used as a proxy to assess the effect of hydrodynamics on the development and structure of intertidal North-East Atlantic rocky macroalgal communities (Brittany). The characterization of hydrodynamics at small-scale (about 10 m) was performed through wave height in situ monitoring using pressure sensors. Both the diversity and the cover of the macroalgal communities were sampled in parallel. Wave heights exhibit large variations with values ranging from ca. 5 cm to 1.60 m. We show that wave height directly controls the cover of macroalgal canopies (Pearson's r between −0.62 and −0.39). In all communities, most of the fucoid covers regressed with increasing wave height values. By contrast, positive correlations were found at low shore levels... |
