“…In agreement with our results, previous studies have pointed out that not only is the quantity of habitat important to modulate the abundance and diversity of invertebrates but also that complexity plays a significant role (e.g. Gee and Warwick, 1994;Hauser et al, 2006;Veiga et al, 2014). Finally, both univariate and multivariate analyses showed the lack of influence of Dp in shaping epifaunal assemblages.…”

“…These results could be the result of the lack of significant differences in the Dp among the studied macroalgae. However, previous studies (Veiga et al, 2014) found that Dp played a minor role in shaping the epifaunal assemblages of perennial macroalgae.…”

“…Vegetated systems usually harbour a higher abundance and diversity of invertebrates than non-vegetated habitats (Currás et al, 1993;Taniguchi et al, 2003). Previous observations suggest a positive relationship between macroalgal morphological complexity and the abundance and diversity of their associated epifauna (Gee and Warwick, 1994;Hauser et al, 2006;Hooper and Davenport, 2006;Veiga et al, 2014). The mechanisms responsible for this positive relationship are not fully understood but many authors suggested that high morphological complexity increases abundance and diversity of epifauna by reducing predation (e.g.…”

“…Por esta razão, a diminuição do Dp acarretaria em um aumento na densidade de espécies de pequeno porte, que conseguiriam se movimentar e aproveitar os recursos presentes entre os pequenos espaços com maior facilidade do que as espécies maiores (JEFFRIES, 1993;THOMAZ et al, 2008;VEIGA et al, 2014).…”

This work constitutes the first comprehensive study of the epifaunal response to biological invasions in coralligenous habitats, which are one of the main hotspots of biodiversity in the Mediterranean. The epifaunal community inhabiting the invasive macroalga Rugulopteryx okamurae and other dominant sessile hosts on coralligenous habitats (i.e. the sponge Spongia lamella, the gorgonian Paramuricea clavata, and the macroalga Sphaerococcus coronopifolius) was characterized. A total of 137 taxa were found. There was a lack of functional equivalence between macroalgal species (both native and invasive) and sessile invertebrates. Despite the absence of significant differences in mean density values and number of species per replicate among host species, epifaunal composition on gorgonians and sponges differed significantly from that on both macroalgae. Epifaunal assemblages, especially those inhabiting macroalgal species, were dominated by generalist detritivorous species that can inhabit different hosts, while specialized interactions between mobile epifauna and sessile hosts were observed almost exclusively on sessile invertebrates. Moreover, epifaunal community associated with invertebrate hosts showed higher spatial heterogeneity in comparison with native and invasive macroalgae. A competitive displacement of native hosts by the spreading of R. okamurae on coralligenous habitats would likely result in a biotic impoverishment in terms of overall number of species and a taxonomical and functional homogenization of the epifaunal community. Specialist species with a heterogeneous distribution could be gradually replaced by a spatially homogeneous assemblage dominated by generalist species.
