Study of the crustacean community associated to the invasive seaweed Asparagopsis armata Harvey, 1855 along the coast of the Iberian Peninsula.

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, s...

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.Se estudió la comunidad de crustáceos asociados al alga Asparagopsis armata en el litoral de la península Ibérica. Se seleccionaron un total de 19 estaciones situadas a lo largo de toda la costa cantábrica, atlántica y mediterránea En cada estación se midieron cinco parámetros fisicoquímicos (temperatura, oxígeno disuelto, salinidad, pH y turbidez), se recolectaron muestras del alga (tres réplicas de 20x20 cm), y se estimó su cobertura (cinco cuadrículas de 50x50 cm) en el intermareal. Los crustáceos fueron el grupo dominante (más del 80% en número de individuos), seguido de anélidos, moluscos y equinodermos. Se identificaron 60 especies de crustáceos (38 gammáridos, siete caprélidos, nueve isópodos, cuatro decápodos y dos tanaidáceos). Los gammáridos y los caprélidos fueron dominantes en número. Aunque los análisis univariantes no reflejaron diferencias significativas en el número de especies, abundancia, diversidad de Shannon y equitatividad de Pielou entre las distintas estaciones, los multivariantes mostraron diferencias en la composición de especies. Según el análisis canónico de correspondencias, la biomasa de alga, la concentración de oxígeno, el pH y la salinidad fueron las variables que mejor explicaron la distribución de las especies. El número de especies de crustáceos encontrado sobre A. armata en este estudio es similar a los registrados en la literatura para otras algas autóctonas.Universidad de GranadaZoología2011info:eu-repo/semantics/articleapplication/pdfapplication/pdfhttp://hdl.handle.net/11441/28283reponame:idUS.
