An annotated and updated checklist of the opisthobranchs (Mollusca: Gastropoda) from Spain and Portugal (including islands and archipelagos)
A new annotated and updated checklist of the opisthobranchs from the Spanish and Portuguese coasts, including their Atlantic archipelagos (Azores, Madeira, Selvagens and Canary Islands), with a total of 117 specific taxa described as new to science in the studied area.
ENVIRONMENTALLY MEDIATED SEX CHANGE IN THE ENDANGERED LIMPET PATELLA FERRUGINEA (GASTROPODA: PATELLIDAE)
It is indicated that sex change appears to occur at smaller sizes when large individuals (presumably females) are rare, and the fact that P. ferruginea may exhibit environmentally mediated sex change could influence population management decisions.

The environmental parameters having the greatest effect on the molluscs associated with Halopteris scoparia are water movement, the morphological characteristics of the substrate, and most importantly the availability of food.

The objectives of this study were to describe the peracaridean fauna associated to the algae Corallina elongata from the Strait of Gibraltar, and explore possible biodiversity and biogeographical…
Effects of environmental stress on ascidian populations in Algeciras Bay southern Spain Possible marine bioindicators
The distribution and abundance of littoral ascidians were analyzed with respect to the possible relationships with environmental stress and some species, such as Ciona intestinalis, could be categorized as species very sensitive to stress, as well as ind~cators of good conditions.

Assessing habitat use of the endangered marine mollusc Patella ferruginea (Gastropoda, Patellidae) in northern Africa: preliminary results and implications for conservation
The Spatial Distribution of Caprellidea (Crustacea: Amphipoda): A Stress Bioindicator in Ceuta (North Africa, Gibraltar Area)
. The caprellid (Crustacea: Amphipoda) community associated with the alga Cystoseira usneoides (L.) Roberts 1967 was studied on a spatial scale in relation to the influence of environmental factors…
Assessing pollution levels in sediments of a harbour with two opposing entrances: environmental implications.
Patterns of spatial genetic structuring in the endangered limpet Patella ferruginea: implications for the conservation of a Mediterranean endemic
The ISSR results suggest that, on a regional scale, the genetic structure of P. ferruginea is mainly determined by the restriction of gene flow by dispersal barriers and human harvesting may play a crucial role in population structuring by increasing the effect of genetic drift.
