Estructura espacial, dinámica temporal y hábitat del poblamiento de peces litorales mediterráneos

Abstract

En esta tesis se aborda la cuantificación, mediante censos visuales, de las pautas de variación espacial y temporal de los poblamientos de peces que viven en los fondos rocosos infralitorales del Mediterráneo occidental, a varias escalas espaciales, y se estima la importancia relativa de la estructura del hábitat rocoso para explicar dichas variaciones. En sucesivos estudios, utilizándose técnicas de análisis espacial, se muestra que riqueza, abundancia y diversidad de peces responden a las variaciones del hábitat estructural (distinguiéndose entre complejidad y heterogeneidad), tanto a escala local como a múltiples escalas espaciales jerarquizadas. Por otra parte, el poblamiento de peces muestra una notable estabilidad temporal, aunque ésta depende de las escalas taxonómica, espacial o analítica considerada, pudiendo esta estabilidad ser debida al efecto del hábitat sobre las poblaciones. La influencia de la estructura del hábitat rocoso puede enmascarar, e incluso contrarrestar, los beneficios esperados de la protección pesquera.
