Los conceptos bioeconómicos modernos invocan la importancia de definir los derechos de propiedad posibles de ser llevados a cabo dentro del contexto de gestión. La investigación pesquera debe considerar las expectativas ...
Esta tesis parte de la concepción de la playa como un sistema integral en el que se desarrollan procesos interrelacionados. El análisis de estos procesos y del marco físico y administrativo donde se producen, es el hilo ...
This thesis presents diverse theoretical and practical applications of the ERS 1/2 and RADARSAT satellite images of the Synthetic Aperture Radar SAR sensor (near 330 images in the Northwest Mediterranean NWM and 980 in ...
En el presente trabajo se analizan aspectos concretos de la biología y ecología de Mullus barbatus y M. surmuletus.<br><br/>En primera instancia, se pretende determinar algunas diferencias biológicas, merísticas y morfométricas ...
The predictability of beach inundation is mainly related to wave runup and most of the formulations that have been developed focus on the hydrodynamics, disregarding the morphological changes caused during storms. For these ...
Humanity is currently using more than 200000 synthetic organic compounds in many industrial, agricultural and domestic applications. Many of these chemicals reach the environment and have a harmful effect on ecosystems and ...
Nephrops norvegicus is an important fishery resource for Europe. Its rhythmic burrowing behavior is strictly related to catchability. Here I studied such behavior under laboratory conditions. I investigated the combined ...
En nuestra sociedad los derivados del petróleo son la fuente principal de energía. Los accidentes con hidrocarburos han protagonizado episodios de contaminación trágicos para la biosfera del océano. Se analizan algunos ...
Aquesta tesi proposa un marc metodològic per a la determinació d'Àrees amb Risc d'Inundació i l'Avaluació de Danys per Tempestes Costaneres, en dues escales de treball: una a llarg termini relacionat amb l'Elevació Relativa ...
Storm-induced impacts are known to cause important economic and environmental damages to coastal systems worldwide. Consequently, the relevance of including hazards and vulnerability assessments in coastal policies has ...
Este trabajo presenta un marco metodológico para la estimación de la vulnerabilidad costera al impacto de tormentas a dos escalas, regional y local. Se hace una evaluación de la vulnerabilidad costera física mediante la ...
Economic approaches through ecosystem services (ES) valuation are increasingly recommended by conservation organisations to face main market externalities affecting biodiversity in general and coral reef ecosystems. In ...
There is increasing evidence that the presence of many emerging pollutants in aquatic ecosystems may have detrimental effects on aquatic biota. Of special concern are those emerging pollutants that may act as putative ...
The main target of this research is to develop a numerical model for debris flow simulations. As it is known, in general, this kind of flows occur in steeped mountain slopes. When dealing with the complete 3D physic system ...
En esta tesis se ha desarrollado y validado un modelo tridimensional de circulación costera en elementos finitos capaz de simular una región limitada del océano. La escala de longitud de las aplicaciones pueden ser del ...
Con el objetivo de desarrollar una herramienta de gestión para la reducción del impacto de los efluentes sobre los ecosistemas receptores de una granja camaronícola en el Estero de Urías, Mazatlán, Sinaloa, México, se ...
En aquest treball es caracteritzen les proteïnes espermàtiques bàsiques (PEB) que condensen el DNA de l'espermatozoide de diferents grups de deuteròstoms, tant procordats (tunicats o urocordats i cefalocordats) com vertebrats ...
Coastal areas are very susceptible to contamination due to the interaction of marine and anthropogenic processes. Persistent Organic Pollutants (POPs) are organic compounds very resistent to photolysis and chemical and ...
The present thesis provides new information about pelagic decapod crustaceans, specially so concerning the Mediterranean pasiphaeids. Remarkable differences in the pattern of distributions of the pasiphaeids were observed ...
Soft-bottom polychaete assemblages inhabiting shallow waters of the northern Mediterranean Spanish coast were studied with the objective to elucidate its present structure, distribution and diversity at different scales ...
