  abstract = {{T}he underexplored intertidal ecosystems of {A}ntarctica are facing rapid changes in important environmental factors. {A}ssociated with temperature increase, reduction in coastal ice will soon expose new ice-free areas that will be colonized by local or distant biota. {T}o enable detection of future changes in faunal composition, a biodiversity baseline is urgently required. {H}ere, we evaluated intertidal faunal diversity at 13 locations around the {G}erlache {S}trait (western {A}ntarctic {P}eninsula), using a combination of a quadrat approach, morphological identification and genetic characterization. {O}ur data highlight a community structure comprising four generally distributed and highly abundant species (the flatworm {O}brimoposthia wandeli, the bivalve {K}idderia subquadrata, and the gastropods {L}aevilitorina umbilicata and {L}aevilitorina caliginosa) as well as 79 rarer and less widely encountered species. {T}he most abundant species thrive in the intertidal zone due to their ability to either survive overwinter in situ or to rapidly colonize this zone when conditions allow. {I}n addition, we confirmed the presence of multiple trophic levels at nearly all locations, suggesting that complex inter-specific interactions occur within these communities. {D}iversity indices contrasted between sampling locations (from 3 to 32 species) and multivariate approaches identified three main groups. {T}his confirms the importance of environmental heterogeneity in shaping diversity patterns within the investigated area. {F}inally, we provide the first genetic and photographic baseline of the {A}ntarctic intertidal fauna (106 sequences, 137 macrophotographs), as well as preliminary insights on the biogeography of several species. {T}aken together, these results provide a timely catalyst to assess the diversity and to inform studies of the potential resilience of these intertidal communities.},
