| The oxygen minimum zone (OMZ) off the Peruvian coast, though shallower and more intense than other OMZs, exhibits a spatial distribution that varies with latitude, depth and distance to the coast. The spatial variability in oxygen content imposes latitudinal and bathymetric zonations of the benthic communities. Nevertheless the spatial patterns of the benthic communities are also modulated by the bottom topography and the sedimentary environments, which in turn are controlled to a large extent by the poleward undercurrent. While the bathymetric patterns of the macro- and meiobenthos have been previously described, latitudinal changes have received less attention. We found that, in parallel with opposed latitudinal gradients of oxygen and fresh organic... |

| This paper is a panoramic, though incomplete, review of the Peruvian marine biodiversity, including the Peruvian coastal upwelling ecosystem, the marine shallow areas of the Peruvian coast and the mangrove ecosystem of the north of Peru. It includes an analysis of the advances in conservation and management, as well as of research resources. The analysis mainly showed the insufficient human resources and the limited facilities in laboratories and coastal research stations. An analysis was also made from the current unknowns of the research at taxonomy and ecosystem levels, indicating scarce studies for most of the taxonomic groups and biological communities. Finally, the consultations and discussions promoted with the scientific community, allowed the... |
