Macrocystis integrifolia and Lessonia trabeculata (Laminariales; Phaeophyceae) kelp habitat structures and associated macrobenthic community off northern Chile

Temporal variation of seston biomarkers within the Humboldt Current System off northern Chile (21°S): first simultaneous records on fatty acids,n-alkanes and glycerol-dialkyl-glycerol-tetraethers (GDGT)

“…Near the coast, the nutrient and organic material as well as the density and biomass of the organisms on the sandy-muddy seabed may be considered high [10]. This coastal system houses a very rich benthic macroalgae community in the shallower area, as well as the intensive harvesting of dense echinoderm, bivalve and gastropod populations [30]. The area exhibits a permanent oxygen minimum zone that is largely associated with high organic production and O 2 consumption through the heterotrophic utilization of organic matter [15][16][17].…”

Successional patterns of hard-bottom macrobenthic communities at kelp bed (Lessonia trabeculata) and barren ground sublittoral systems

“…In shallow hard-bottom habitats, kelp beds formed by brown macroalgae (mainly species of the order Laminariales) construct continuous and/or patchy forests that dominate temperate coastal regions (Steneck et al, 2002;Bolton, 2010). Kelp beds are very important because they provide habitat complexity, food resources and shelter, thus harbouring high levels of biodiversity compared with their barren ground counterparts (Dayton, 1985;Graham, 2004;Villegas et al, 2008). In contrast, barren grounds appear to flourish when kelp beds decay (Steneck et al, 2002;Flukes et al, 2012) and are principally dominated by crustose coralline algae and sea urchin species (Chapman, 1981).…”

Short‐ and long‐term acclimation patterns of the giant kelp Macrocystis pyrifera (Laminariales, Phaeophyceae) along a depth gradient

“…, Villegas et al. ). Additionally, sporophytes may become detached from the substratum and may act as long‐distance dispersal vectors during their extensive free‐floating periods (~1,000 km in 100 d; Macaya et al.…”
