“…Polychaetes were as- Chintiroglou (1996), Antoniadou and Chintiroglou (2005), Antoniadou (2014), Faulwetter et al (2014) and the World Register of Marine Species (WoRMS) (www.marinespecies.org). Crustaceans were also assigned to feeding groups according to data from Hazlet (1962), Gambi et al (1992), Birkely and Gulliksen (2003), Tanaka (2007), Voultsiadou et al (2007), Navarro-Barranco et al (2013), Guerra-Garcia et al (2014) and WoRMS. Number of taxa and abundance per feeding group were measured for the two studied sponges, while density of symbionts per feeding group was calculated for every sponge specimen.…”

“…In contrast, Amphilochidae and Stenothoidae did not show clear differences along the Sargassum thallus. These families are represented by amphipods with detritivore and predatory feeding habits (Guerra-García et al, 2014) and, as a result, they may be less dependent on the detritus accumulated at the basal portion of Sargassum. Furthermore, Caprellidae (mainly composed by detritivore species) was denser in the distal portion of Sargassum.…”

“…These organisms were preserved in alcohol 70% and the amphipods were identified to the family level. We identified up to the families because the feeding habits are usually shared at this level, including the amphipod species commonly found in Sargassum in the studied region (Barnard and Karaman, 1991;Guerra-García et al, 2014). The macroalgae were dried at 70 ºC for 24 hours and weighed to estimate the density of amphipods.…”

“…To verify the families that most contributed to the dissimilarities between the Sargassum portions, we performed a SIMPER analysis. Moreover, we classified families according to their predominant feeding habits (herbivores, detritivores and predators) (Barnard and Karaman, 1991;Guerra-García et al, 2014). Finally, to compare amphipod diversity and Sargassum biomass between basal and distal portions, we used Student's t test for independent samples.…”

“…Among its associated fauna, the amphipods present high abundance and species richness (Tanaka and Leite, 2003;Jacobucci et al, 2009), making them especially sensitive to changes in the spatial physical structure of the substrates. The amphipod assemblage associated to Sargassum presents distinct behavior and feeding habits (herbivores, predators and detritivores) (Barnard and Karaman, 1991;Guerra-García et al, 2014) that can promote changes in the species community regarding their use of microhabitats. In this study, we tested if the amphipod assemblage varies along different portions of the Sargassum thallus.…”

Variation of amphipod assemblage along the Sargassum stenophyllum (Phaeophyta, Fucales) thallus

et al. 2015

-The spatial distribution of fauna associated to marine macroalgae has mostly been investigated considering a horizontal plane. However, the macroalgal substrates can present a three-dimensional structure. In this sense, investigating how the associated fauna varies throughout a vertical plane can contribute to understanding the distribution of these organisms. The brown macroalga Sargassum presents a vertical stratification along its thallus and harbors an amphipod fauna with a variety of feeding habits. In this work, we tested if the amphipod assemblage varies along different portions of the Sargassum thallus. We collected whole Sargassum stenophyllum thalli, as well as isolated basal and distal portions, from a rocky shore located on the north coast of São Paulo, in southeastern Brazil. The composition of amphipod families varied according to the Sargassum portion and the families Corophiidae, Caprellidae and Hyalidae accounted for most of the differences. Moreover, the basal portion of Sargassum had a higher diversity of amphipod families than the distal one, which may be related to differences regarding habitat complexity (herein, measured as algal biomass) between these portions. Detritivores (such as Corophiidae) were more associated to the basal portion and herbivores to the distal portion (Hyalidae) or along the whole Sargassum thallus (Ampithoidae). The variation of amphipod assemblage along Sargassum thallus seems to result from the interaction between the fauna natural history and the differences in conditions and physical structure along the algal thallus. In this sense, the vertical stratification of Sargassum can add another source of variation to the spatial distribution of associated fauna.(GBOM, SAD) Pós

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.
