“…The most outstanding species were the shrimp Crangon crangon, the sea urchin, Echinocardium cordatum and crabs, Pachygrapsus marmoratus, Portumnus latipes and Liocarcinus depurator. In the samples, we also found the mysid Siriella armata, that is characterized as a model species in ecotoxicology studies (Pérez et al, 2010); the isopod Centraloecetes dellavallei that has an abundance that is inversely proportional to the amount of organic matter in the environment (Muñoz-Lechuga et al, 2018) and the isopod Lekanesphaera weilli which is considered as a good ecological indicator (Reyes- Martínez et al, 2015). In addition, new records have been obtained of the polychaetes Glycera tridactyla, Onuphis eremita and Sthenelais boa on the Atlantic Cadiz coast (Muñoz-Lechuga et al, 2018).…”

“…Abstract: Sandy beaches are ecosystems that connect marine and terrestrial systems, where macroinfauna play a very important role in the food web. In addition, these systems provide some advantages such as: sedimentation, decomposition of organic matter, storm dissipation, filtration and water purification (Ricciardi et al, 1999;Muñoz-Lechuga et al, 2018). Due to the relevance and interest that macroinvertebrates have in these areas, the aim of this work was to characterize the most relevant species of six beaches of the Cadiz coast (southwest of Spain): Santa María del Mar, Torregorda, Camposoto, Punta del Boquerón, La Barrosa and Caños de Meca.…”

Twelve species were identified and obtained by means of a modified manual dredge (Muñoz-Lechuga et al, 2018). The most outstanding species were the shrimp Crangon crangon, the sea urchin, Echinocardium cordatum and crabs, Pachygrapsus marmoratus, Portumnus latipes and Liocarcinus depurator.…”

<p class="Body">Mediterranean Outflow Water (MOW) acts as a net source of salt and heat into North Atlantic intermediate depths that ultimately contributes to the Atlantic Meridional Overturning Circulation. On this basis, it has been hypothesised that MOW variability might influence global climate. Although several studies have documented major glacial-interglacial changes in deep- and intermediate Mediterranean circulation patterns, little is known about associated impacts on MOW properties, in particular its residence time and geochemical signature. Using a set of cold-water coral samples from along the &#8216;pre-MOW&#8217; and MOW path, i.e. from the Alboran Sea to the northern Galician Bank including the Strait of Gibraltar and the Gulf of Cadiz, we aim to identify changes in both the ventilation state of the water masses flowing out of the Mediterranean and the distribution of coral growth.With this purpose, paired Uranium-series and AMS radiocarbon ages have been obtained in the same coral samples allowing any potential change in the reservoir age to be inferred accurately, as well as allowing a spatio-temporal &#8216;coral map&#8217; to be created. Furthermore, these results have been complemented by trace element measurements in benthic foraminifera from the Alboran coral mound sediment core.</p> <p class="Body">Our results show a particular spatio-temporal coral distribution with glacial presence only at the deepest sites of the Gulf of Cadiz (~1000m), followed by ~300m Western Mediterranean (WMed) coral appearance across the deglaciation/mid Holocene (14-4 kyr), to end with a proliferation at the Strait of Gibraltar and Galicia Bank from ~6 kyr towards the present. We hypothesise 1) that ~300m WMed area might have been bathed in Atlantic waters inflow during the glacial due to sea-level drop, returning to LIW (Levantine Intermediate Water) influence over the deglaciation, and 2) that MOW reached deeper areas outside of the Mediterranean Sea in the Gulf of Cadiz during the glacial period. Regarding the reservoir age, little change at the WMed is observed at 150-450m across the deglaciation as compared to the large ventilation excursion detected in the Iberian Margin at ~1000m. However, a ventilation age gradient of ~300 yr related to water depth is observed within WMed corals when appearing at the B&#248;lling-Aller&#248;d, in synchrony with significant changes in hydrographical parameters inferred from foraminiferal trace element from the same area. Overall, our results suggest a water mass reorganization at the surface-intermediate layer of the WMed during the deglaciation and early Holocene, but the ultimate nature of these changes needs yet to be explored by further analysis of Nd isotopes as well as of trace elements beyond the deglaciation.</p>

“…Clavijo et al (2005) y Scarabino et al (2006aScarabino et al ( , 2006b) realizaron una recopilación de datos faunísticos (distribución, taxonomía y conservación) de la malacofauna en ambientes marinos y estuarinos costeros bentónicos uruguayos (0-50 m). Tener conocimiento de la malacofauna autóctona es fundamental para resolver inconvenientes ligados al empobrecimiento faunístico por contaminación, o invasiones biológicas que transforman la diversidad de los ambientes litorales acarreando situaciones ecológicas adversas (Darrigan y Arcaria, 2011;Muñoz-Lechuga et al, 2018). En este sentido, por ejemplo, en las costas argentinas atlánticas y rioplatenses se ha detectado contaminación con tributil-estaño (TBT) en sedimentos y aguas, cuyos efectos indeseables se asocian a malformaciones en caracoles marinos que provocan problemas ecosistémicos (Bigatti et al, 2011).…”

La presión antrópica sobre la malacofauna también es un riesgo que repercute en cambios ecológicos, la implementación de áreas protegidas y el enfoque ecosistémico en pesquerías, por lo que el manejo adecuado del agua de lastre y de productos químicos deben ser considerados para la conservación de la fauna costera (Scarabino et al, 2006a(Scarabino et al, , 2006bMuñoz-Lechuga et al, 2018).…”

Los ambientes costeros están siendo afectados a escala global por una excesiva urbanización, crecimiento industrial y turismo, generando erosión, pérdida de biodiversidad y alteración del ecosistema; estas alteraciones constituyen potenciales riesgos con consecuencias negativas tanto ambientales como socioeconómicas. El sector litoral uruguayo, caracterizado por amplias playas de arenas separadas por promontorios rocosos, no es ajeno a esta problemática mundial. Considerando aspectos geomorfológicos, sedimentológicos y malacológicos se pretende comprender el impacto antrópico en la dinámica litoral para contar con una base de datos que sirva para evaluar el manejo del recurso playa. Para ello se compararon siete playas del Departamento Maldonado, una de las cuales se encuentra en el ambiente estuarial mientras que las demás están sobre el margen atlántico, con distintos grados de antropización y urbanización. A través del análisis geomorfológico, haciendo uso de imágenes satelitales, modelos digitales de elevación, procesamiento y almacenamiento de datos en un sistema de información geográfico, se parametrizó cada subambiente costero (mesoplaya, supraplaya, duna y duna modificada) teniendo en cuenta área, ancho, pendiente y perfil transversal en cada sitio. El análisis granulométrico permitió caracterizar cada localidad y cada subambiente; mediante estadística se pudo establecer una relación entre el aumento de la desviación estándar y la antropización en la franja litoral. La composición faunística particularizó cada playa, además mediante el cálculo de distintos índices se identificaron los sitios con mayor diversidad y dominancia. Se determinó que la antropización en la franja costera mediante incipiente desarrollo urbanístico modifica el sector de dunas generando una reducción de todos los subambientes, exponiendo zonas más vulnerables a la erosión inducida. Se espera que este trabajo sea útil en la planificación del ambiente litoral e identificación de zonas críticas.
