| Sumario: | We studied the community of crustaceans associated to the seaweed Asparagopsis armata along the coast of the Iberian Peninsula. Nineteen stations were selected along the Cantabrian, Atlantic and Mediterranean coast. In the intertidal, five physicochemical parameters (temperature, dissolved oxygen, salinity, pH and turbidity) were measured at each station; algae samples were collected (three replicates of 20x20 cm), and its coverage was estimated (five grids of 50x50 cm). Crustaceans were the dominant group (over 80% in number of specimens) followed by annelids, molluscs and echinoderms. We identified a total of 60 crustacean species (38 gammarids, seven caprellids, nine isopods, four decapods and two tanaids). The caprellids and gammarids were dominant in number. Although univariate analysis showed no significant differences regarding the number of species, abundance, diversity and evenness of Pielou among stations, the multivariate analysis showed different species composition. According to the canonical correspondence analysis, the biomass of algae, as well as the oxygen concentration, pH and salinity were the variables that best explained the distribution of species. The number of crustacean species found on A. armata in this study is similar to that recorded in the literature for other native algae. |
