C old seeps (CS) support chemo-biotic faunistic associations; the scarce research carried out into the Pacific
Sea Coast of America had led the focus, towards the understanding of the relationship between those and
the methane hydrate deposits, thus finding biodiversity is somehow related to substrate kind. Our research
purpose was to bring some light on the ecologic association of present macroinfaunal communities and its rel-
evance with CS, to accomplish, we studied the communities at CS, starting from raw bibliographic data mining,
stored and compiled on MySQL’s database engine; relied about the Pacific America continental margin, on facts
of diversity and distribution, in accordance with its altitudinal range (South and North Cold Areas SCA–NCA and
Tropical Area-TRA) reports. With the stored data we conducted analysis as Beta-diversity indexes (Chao1, Bray
Curtis), the Olmstead and Tukey’s statistical Ranking and the Kruskal Wallis’s ANOVA test. The results showed
absence of continuous distribution between the assessed areas, indicating species heterogeneity; thus, lead-
ing to understand that the better growth progression adjustment, related to diversity and heterogeneity come
about in SCA; we identified that Ampharetidae and Solemyidae staked as dominant taxonomic groups on
NCA and TRA. The poor similarity observed on the communities dynamics, shows an ecological erratic nexus,
stimulating ecological composition and distribution relied on metacommunities. Through the analysis, Vesico-
myidae and Siboglinidae showed as cosmopolitan taxonomic groups, and also as dominance indicators related
with its prevalence on CS’s continental margins; thus, the current range of distribution is favored in addition by
the continental drift effect; which in conjunction with the marine environment variability and dynamics influ-
enced the spatial arrangement of populations in metacommunities.
Janeth Viviana Pérez Arteaga got her bachelor degree from the Valle’s University, in Cali-Colombia in 2007. Currently, she is Earth
Sciences Master’s student at the EAFIT’s University, Colombia and also partaking as researcher of the Biodiversity, Evolution and
Conservation Researcher’s Group at the same institution. She has produced four scientific documents laying on biodiversity. Her
area of interest is to serve as an environmental consultant on port and marine issues and diary work has led her to get extensive
expertise in coastal-marine issues and ecological impact assessment. As a part of her personal and labour development she has
been jury on dissertation and scientific research work.
