Resumen


Los lechos de maerl y, en particular, los de Bretaña, son un importante hábitat costero biogénico y estructuralmente complejo, que forma un ecosistema único con una alta biodiversidad bentónica. A pesar de que varios grupos faunísticos son relativamente bien estudiados en toda Europa, aquellos pertenecientes a la meiofauna han recibido poca atención. Hemos investigado la abundancia, distribución y estructura de la comunidad de la meiofauna, con especial atención a la biomasa y diversidad de nematodos de un área de maerl en la bahía de Brest (Bretaña), en comparación con la de una playa de arena (Anse de Dinan, Bretaña). La meiofauna del maerl fue cinco veces más abundante que la de la playa arenosa, y 1,5 veces más diversificada (12 taxones frente a 8 respectivamente). La diversidad de nematodos del maerl fue más de tres veces mayor que la de la playa arenosa y mostró un único nematodo que, a su vez, resultó ausente en la playa arenosa. Los lechos de maerl crean microhábitats más heterogéneos y promueven una mayor diversificación de la meiofauna y las comunidades de nematodos que los hábitats de playas arenosas.
