Global changeRevista de Investigación Marina, 2012, 19(6) |  459Is invasive macroalgae Lophocladia lallemandii inducing changes in epiphyte community of endemic bivalve Pinna nobilis?Gàlia Banach Estevea, Maite Vázquez Luisa and Salud Deuderoa Invasive species are one of the main factors that threat ecological communities. The red alga Lophocladia lallemandii (Montagne) F. Schmitz is a recognized invader in marine ecosystems around the Mediterranean. The aim of the present study is to characterize the structure of the epiphytic native species of Pinna nobilis population in the Archipelago of Cabrera National Park (ACNP) among which L. lallemandii is attaining high colonization rates. The study is integrated in a protected area where it is least influenced by human activity, and consequently, less impacted by invasive macroalgae. Although we found that more than a half of the population of P. nobilis in Cabrera was epiphyted by L. lallemandii. The study was carried out monthly during eight months, from April to November 2011, according to the length size distribution of P. nobilis population census in the ACNP: 3 small (≤19 cm), 4 medium (19-38 cm) and 3 large (>38 cm). It has been quantified a total of three size ranges in a population with a high number of individuals. The community of native epiphytes on the shell of P. nobilis has high ecological importance because it is a centre of aggregation and contributes to increase the biotope complexity level. The results suggest that the presence of the invasive macroalgae L. lallemandii produce changes on the composition of the native species on the fan mussel P. nobilis individuals in the ACNP. Native species of P. nobilis denote a high variability in the number of species, species coverage and species richness. Diversity of native species declines over time with the presence of L. lallemandii. a Instituto Español de Oceanografía, Centro Oceanográfico de Baleares, Muelle de Poniente s/n, 07015, Palma (Email: galia.banach@ba.ieo.es)
