Seasonal variation of the macrofauna from three seagrass meadows of Cymodocea nodosa off Gran Canaria (central-eastern Atlantic ocean)

Seasonal variation of the macrofauna from three seagrass meadows of Cymodocea nodosa off Gran Canaria (central-eastern Atlantic ocean)

Gastropoda, Bivalvia, Polychaeta and Crustacea are the four main taxonomic groups of macrofauna associated with three seagrass meadows of Cymodocea nodosa at Gran Canaria (Canary Islands, Spain); eight taxa were found. The density and Shannon-Weaver index (H') indicated a clear unimodal behavio...

The density and Shannon-Weaver index (H') indicated a clear unimodal behaviour, with maxima in spring and summer, and minima in winter, whereas the evenness index (J') indicated stability throughout the year. This can be attributed to seasonal migrations of a reproductive or nutritional nature in spring and summer of certain taxa. A correlation analysis showed a significant positive relationship between the seasonal cycles of the macrofaunal density and the plant biomass for the meadows studied. Gastropoda, Bivalvia, Polychaeta y Crustacea son los cuatro grupos taxonómicos principales de macrofauna asociados con tres praderas marinas de Cymodocea nodosa en Gran Canaria (Islas Canarias, España), habiéndose encontrado un total de ocho taxones. La densidad y el índice de Shannon-Weaver (H') muestran un claro comportamiento unimodal, con máximos en primavera y verano y mínimos en invierno, mientras que el índice de equitatividad (J') mostró estabilidad a lo largo del año. Esto es atribuible a migraciones estacionales de carácter reproductivo o alimenticio en primavera y verano de determinados taxones. Un análisis de correlación mostró una relación significativa positiva entre los ciclos estacionales de la densidad de macrofauna y la biomasa vegetal para las praderas analizadas.
