| Sumario: | The distribution and abundance patterns of isopods, tanaids and cumaceans (Crus - tacea: Peracarida) associated with the alga Stypocaulon scoparium (L.) Kützing were studied. Fourteen stations were selected along the Iberian Peninsula and five environmental factors were measured (seawater temperature, conductivity, dissolved oxygen, turbidity and pH). The Atlantic coast was characterised by lower temperature and conductivity and higher values of oxygen and turbidity than the Mediterranean coast. Cover of S. scoparium was higher in the Strait of Gibraltar than in the remaining stations, coinciding with maximum values of number of peracaridean species. Twenty three species were collected (15 isopods, 4 tanaids and 4 cumaceans). Isopods were more abundant in Atlantic stations of the Iberian Peninsula while tanaids and cumaceans were dominant in the Mediterranean coast. The classif ication of species in geographical distribution groups showed that most species had an Atlantic-Mediterranean distribution (76%) and only 9% were endemic Mediterranean species. Multivariate analy - sis showed that distribution of species was mainly correlated to temperature, conductivity and oxygen, although the cover of S. scoparium also influenced the abundances of some taxa. |
