This fact, added to the growing anthropic pressure marine ecosystems face in the U-EEZ, increases the vulnerability of these ecosystems and their associated biodiversity. Despite this, there is valuable and abundant disaggregated environmental and biological information for benthic systems.MethodsIn this work, we used ca. 4000 records of all major Phyla of benthic invertebrates to determine discrete benthic regions for the U-EEZ. We looked at the structuring forces of bathymetry, salinity, and water masses. First, we categorized the multivariate structure according to statistical significance to test a priori categories for univariate descriptors. Then, we mapped unique combinations of categories of structuring variables, which largely determine the structure and composition of benthic communities. Operationally, ...

This information is allowing for a growing number of ecological, biodiversity informatics or conservation projects. Most of this information comes from Natural History Collections (NHC) worldwide. Despite well-known limitations, NHC data are particularly useful as a source of data on invertebrates, which comprise about 99% of animal life. However, a presumably very high amount of PBD is still not digitally accessible. Even the most important scientific collections in developed countries are not fully inventoried or digitally accessible. Furthermore, species determination rates remain alarmingly low for some collections, and most existing determinations probably should be retested. This is particularly true of expensive, difficult-to-obtain deep-sea benthic samples. This paper reviews the database on material collected by the German RV ‘Walther Herwig I and II’ during...
