RESUMEN: El objetivo general de esta tesis es desarrollar una metodología de clasificación de la costa intermareal rocosa a escala Europea (Nordeste Atlántico), regional (Norte y Noroeste de la Península Ibérica) y local (Cantabria). La metodología está basada en el análisis de características abióticas que determinan la distribución de especies de macroalgas, teniendo en cuenta los requerimientos específicos de cada nivel espacial. Los datos físicos se han obtenido a través de procedimientos específicos (e.g., datos de satélite y modelado numérico) y se han examinado mediante análisis estadísticos. Así, se han obtenido grupos con significado ecológico caracterizados por diferentes comunidades y especies. Además, se ha analizado la relación entre variables geomorfológicas y las especies de macroalgas intermareales a escala local. La aproximación metodológica propuesta ofrece una herramienta estadística objetiva para la definición de regiones ecológicas, que puede ser útil para la protección ambiental y la gestión de zonas marinas.
ABSTRACT: The general objective of this thesis is to develop a methodology for the classification of intertidal rocky shores at three different scales: European (NE Atlantic), regional (N and NW Iberian Peninsula) and local (Cantabria). The methodology is based on the analysis of the abiotic characteristics that determine the macroalgae species distribution, taking into account the specific requirements of the different spatial levels. Physical data obtained by specific procedures (e.g., satellite data and numerical modelling) and examined by statistical analyses is applied to obtain groups with ecological significance characterised by different communities and species distribution. Additionally, the relation between geomorphological variables and rocky intertidal macroalgae species was analyzed at local scale. The feasibility of this methodological approach as a useful tool for the assessment of coastal systems at the three scales was tested.
