Fig. 1. Map indicating the study sites of Playa de Las Salinas, Bocabarranco and Quintanilla at Gran Canaria (Canary Islands, Atlantic Oceans)
Figs 2‒3. Fig. 2. Boxplot showing the difference of the total diatom abundance during summer and winter. Fig. 3. Boxplot showing the difference of the total diatom abundance during summer and winter in relation to the ecological aggregations of the host thalli (i.e. turf and clump)
Table 1. Qualitative and quantitative abundance of epiphytic diatoms from five species of Gelidiales collected in summer 2007 and winter 2008 at three localities in Gran Canaria (i.e., Quintanilla, Bocabarranco and Playa de Las Salinas) in relation to their ecological aggregations (turf, clump). vr = very rare; r = rare; s = sporadic; f = frequent; c = common
Fig. 4. Contribution of the different life ecological forms of the benthic diatoms (i.e. motile, erect, adnate) to total diatom abundance at each turf and clump per season (i.e. winter and summer)
Figs 5‒6. Fig. 5. Boxplot showing the difference of the total diatom abundance in the three localities of Playa de Las Salinas (S), Bocabarranco (B) and Quintanilla (Q). Fig. 6. Percentage contribution of abundances for each diatom form (i.e. motile, erect, adnate) in the three localities of Playa de Las Salinas (S), Bocabarranco (B) and Quintanilla (Q)
Figs 7‒8. Fig. 7. Percentage contribution of abundances for each diatom form (i.e. motile, erect, adnate) in the different host species (i.e. Pc = Pterocladiella capillacea, Ga = Gelidium arbuscula, Gc = G. canariense, Gp = G. pusillum, Pm = P. melanoidea). Fig. 8. Boxplot showing the difference of the total diatom abundance in the different host species (i.e. Pc = Pterocladiella capillacea, Ga = Gelidium arbuscula, Gc = G. canariense, Gp = G. pusillum, Pm = P. melanoidea)
Figs 9‒10. Fig. 9. Boxplot showing the difference of the total diatom abundance in the different levels along the host thalli (i.e. apex, middle, base) per clump. Fig. 10. Boxplot showing the difference of the total diatom abundance in the different levels along the host thalli (i.e. apex, middle, base) per turf
