Effectiveness of European Atlanto-Mediterranean MPAs: Do they accomplish the expected effects on populations, communities and ecosystems?

2008

The success of MPAs in conserving fishing resources and protecting marine biodiversity relies strongly on how well they meet their planned (or implicit) management goals. From a review of empirical studies aiming at assessing the ecological effects of Mediterranean and Macaronesian MPAs, we conclude that establishing an MPA is successful for (i) increasing the abundance/biomass, (ii) increasing the proportion of larger/older individuals, and (iii) enhancing the fecundity of commercially harvested populations; also, MPAs demonstrated to be effective for (iv) augmenting local fishery yields through biomass exportation from the protected area, and (v) inducing shifts in fish assemblage structu…

Repaso a la evidencia isotópica sobre alimentación en la prehistoria valenciana durante el Mesolítico y el Neolítico

2016

Los análisis de isótopos estables son una herramienta fundamental a la hora de reconstruir la alimentación de poblaciones prehistóricas. Hasta hace poco este tipo de análisis no se había aplicado en nuestra tierra. Sin embargo, desde hace unos años el Este de la Península Ibérica se está convirtiendo en uno de los lugares del Mediterráneo donde se está realizando un mayor número de este tipo de estudios. Este artículo explica el potencial de los análisis isotópicos de carbono y nitrógeno sobre colágeno óseo para reconstruir las pautas alimentarias de poblaciones pasadas. También repasa todos los estudios publicados en tierras valencianas de cronología prehistórica publicados hasta la fecha,…

Efeitos da sustentabilidade e valor logístico nas relações entre empresas de transporte marítimo

2020

Resumen El objetivo de este trabajo fue analizar cómo la sostenibilidad (económica, social y ambiental), bajo el enfoque de triple línea base, afecta la calidad de servicio, el valor logístico y la satisfacción en empresas del sector marítimo. Se propone un modelo teórico que se contrasta con la información suministrada por una muestra de 50 responsables de empresas (transitarios, importadores y exportadores) en Panamá. La información se analiza mediante la estimación de regresión por mínimos cuadrados parciales, que permite confirmar el carácter multidimensional de la sostenibilidad y del valor logístico. Los resultados también confirman que las percepciones de los clientes sobre las inici…

Modeling Macroalgal Forest Distribution at Mediterranean Scale: Present Status, Drivers of Changes and Insights for Conservation and Management

2020

Macroalgal forests are one of the most productive and valuable marine ecosystems, but yet strongly exposed to fragmentation and loss. Detailed large-scale information on their distribution is largely lacking, hindering conservation initiatives. In this study, a systematic effort to combine spatial data on Cystoseira C. Agardh canopies (Fucales, Phaeophyta) was carried out to develop a Habitat Suitability Model (HSM) at Mediterranean scale, providing critical tools to improve site prioritization for their management, restoration and protection. A georeferenced database on the occurrence of 20 Cystoseira species was produced collecting all the available information from published and grey lit…
