Relationship between taxocenoses of decapod crustaceans and characteristics of coastal detritic bottoms in the east and southeast of the Spanish coast

Abstract

This paper studies the composition of decapod crustacean populations in coastal detritic bottoms of east and south- east Spain. A series of statistical analyses were performed in order to compare composition and diversity. The decapod taxocenoses shows higher levels of abundance, wealth and diversity in the locations identifi ed as typical detritic bottoms. Finally, some groups of species could be used for typify the biocenoses of typical coastal detritic bottom, like: Paguristes eremita, Ebalia edwardsi, E. deshayesi, Eurynome aspera, Galathea intermedia, Parthenope massena, and Anapagurus hyndmani; the biocenoses of muddy coastal detritic bottoms: Ebalia tuberosa, Atelecyclus rotundatus, Ethusa mascarone and Liocarcinus zariquieyi; and Muddy sand biocenoses: Up- ogebia deltaura, Goneplax rhomboides.
