[ES] Hemos realizado una serie de consideraciones con respecto a la Directiva 2006/7/CE para lograr su correcta aplicación en las playas de baño de Canarias. En nuestras aguas se producen algunos fenómenos que no se producen en el resto de la Unión Europea. Por esta razón hemos establecido una serie de conceptos que no están previstos de forma explicita en los artículos de la Directiva y que, con algunas matizaciones, podremos adaptarlos a la generalidad de la Directiva, o ?sensu contrario?, adecuar la Directiva a nuestra realidad ambiental. En este sentido, hemos adaptado conceptos como ?contaminación de corta duración?, ?tendencia a la proliferación de macroalgas?, ?tendencia a la proliferación de fitoplancton marino?, ?proliferación de cianobacterias? y otros a las especificidades que se producen en nuestras costas y que podrían alterar la calidad de las aguas de baño

[EN] Playa Barca is a 370 m long beach located within the system of the Leeward beaches on the Jandía peninsula, Fuerteventura. This system of beaches represents one of the major sources of economic income to the island, both because of its natural landscape that attract a specific type of tourism, and because of its particular climate conditions that make these beaches ideal for practicing wind-water sports. Nevertheless, in the past decades, this area has suffered from a significant and worrying coastline retreat. In order to look for an explanation to this retreat, five topographic surveys were carried out in October 1999, February 2001, February 2002, February 2003 and February 2013 to track the beach behavior in the last 15 years. A total station Topcon GTS-303D was used for this purpose. Surveys were carried out during low spring tides, so that the outer limit was the furthest possible depending on wave conditions. The inner limit covered part of the dunes in the backshore. From these topographic data both coastline changes and the sedimentary balance have been obtained.

[EN] Nesting beach surveys are the most widely implemented monitoring tool in use by the global sea turtle community and are an important component of a comprehensive program to assess and monitor the status of sea turtle populations. These assessments are necessary to evaluate the effects of recovery and conservation activities that are being implemented at all life history stages. Monitoring techniques employed on nesting beaches range from highly structured standardized sampling to “snapshots” of nesting activity within a nesting season. Very long-term nest counts data (more than twenty years) were analyzed for some turtle populations.

[EN] The 70 km of white sandy beaches of Boa Vista island in Cape Verde harbours one of the largest rookeries of the endangered loggerhead sea turtle, Caretta caretta. From middle June to early October, approximately 2000 to 4000 females lay up to 20000 nests annually. However, female beach selection, nesting success and nest density strongly varies among beaches and spatial patterns of nest abundance and distribution are relatively constant among seasons. The numbers of nesting activities and nests have been recorded along all beaches of the island during four nesting seasons (2007-2010)

In this work, accretion and eros ion processes in intertidal strips of sandy beaches are modelled. With that aim the following steps have been made: 1.- Topographic monitoring of a beach in the Island of Gran Canaria (Spainl. 2.- Development of a mathematical modelo 3.- And interpretation of a significative time serie of records of sedimentary volumes. RESUMEN Se pretende modelizar los procesos de acreción y erosión en franjas intermareales de playas arenosas. Para ello: 1. Se ha hecho el seguimiento de los cambios topográficos de una playa de Gran Canaria (España). 2. Se desarrolla un modelo matemático. 3. y se interpreta una serie temporal de balances sedimentarios

[ES] La isla La Graciosa está situada al noroeste de Lanzarote y tiene una extensión de 27,05 km2. Se trata de un área que presenta un alto valor ecológico pues está protegida a través de diferentes figuras tales como: Parque Natural y Reserva Marina del Archipiélago Chinijo, Reserva de la Biosfera de Lanzarote, Zona de Especial Protección de aves (ZEPA) y Zona de Especial Conservación (ZEC), entre otras. En la isla hay varios sistemas playa-duna tanto en la mitad nororiental de la isla (Las Conchas, Lambra y El Jablillo) como en su parte meridional (Barranco de Los Conejos, Las Caletas, El Salado y Francesa). Algunas de las playas muestran evidencias de un déficit sedimentario pues tienen una reducida o nula entrada de sedimentos arenosos al sistema y/o muestran procesos erosivos que hacen aparecer el substrato rocoso. Además, se observa en el interior de la isla la estabilización de los mantos eólicos por la vegetación. Estos ambientes eólicos costeros son esenciales, tanto para la preservación de los ecosistemas protegidos, como para la actividad turística insular. En este contexto se están desarrollando investigaciones multidisciplinares para elaborar un diagnóstico científico de esta problemática ambiental, determinando si las causas de este déficit sedimentario son naturales o antrópicas, y proponer soluciones al respecto.

[EN] For sea turtles, to hatch and emerge from the nest communally is essential to decrease hatchling mortality. Thus, it is very important within a nest the simultaneous fertilization and the synchronized embryonic development of all eggs. On loggerhead nesting beaches of Cape Verde we have studied the individual variability on developmental synchrony of embryos and the influence on this process of some biological, environmental and management factors. We have compared this trait within and between 34 nests naturally incubated on the beach and 34 nests relocated to a beach hatchery during the 2009 and 2010 nesting seasons.
