Tide pools stand out as highly variable and distinctive ecosystems within the intertidal zone. Despite the accessibility of this environment for study, there has been a relatively limited focus on tide pools specifically. This study addresses this gap, aiming to enhance our understanding of variations among tide pools, considering factors such as depth and size. The brown algae Cystoseira humilis serves as the study model due to its prevalence in the tide pools of Gran Canaria. A total of 80 samples, with 10 replicates from each tide pool, were collected using a quadrat method measuring 25 cm x 25 cm in two distinct sites within each tide pool. The chosen method, though destructive, involves scraping the delimited area with a spatula to collect all material, facilitating the study of epifaunal community. Among the 6,068 organisms identified, spanning 48 species, a substantial 95% were classified as amphipods. Depth emerged as the most influential factor impacting the epifaunal community, followed closely by pool size. Notably, the study of species dissimilarity revealed that, when considering pool size, the isopod Dynamene edwarsi made the most significant contribution to dissimilarity. Conversely, when depth was the focal factor, the amphipods Apohyale perieri and Ampithoe rubricata stood out, with higher abundances in deep tide pools compared to shallow ones. Consequently, both size and depth emerged as pivotal factors influencing the studied epifaunal communities. For future ecological studies, it is crucial to account for the tide pool position in the intertidal zone and the level of hydrodynamic exposure at each site. Additionally, broadening the scope to include comparisons with tide pools from other regions and considering the presence of other algal species could provide further insights into differences in epifaunal communities.
