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

espanolThis paper studies the composition of decapod crustacean populations in coastal detritic bottoms of east and southeast 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: Upogebia deltaura, Goneplax rhomboides. francaisNous avons etudie la composition des populations de crustaces decapodes a l'Est des fonds detritiques circalittoral et du Sud-Iberique par rapport aux differents facies, la realisation de diverses analyses statistiques sur la composition et la diversite. Le taxocenosis crus taces decapodes montre des valeurs elevees de l'abondance, la richesse et la diversite dans les endroits identifi es comme des fonds detritiques cotiers aspect typique. Enfi n, certains groupes d'es peces pourraient etre utilisees pour caracteriser les debris de fonds typiques biocenose cotieres, telles que: Paguristes eremita, Ebalia edwardsi, E. deshayesi, Eurynome aspera, Galathea intermedia, Parthenope massena et Anapagurus hyndmani; biocenose des boueuse detritiques cotiers: Ebalia tuberosa, Atelecyclus rotundatus, Ethusa mascarone, Liocarcinus zariquieyi; et biocenose sable vaseux: Upogebia deltaura, Goneplax rhomboides.
