A new assessment of the global biodiversity of decapod Crustacea (to 31 December 2022) records 17,229 species in 2,550 genera and 203 families. These figures are derived from a well-curated dataset maintained on the online platform DecaNet, a subsidiary of the World Register of Marine Species (WoRMS). Distinct phases are recognised in the discovery...

The analysis of biological and ecological traits has a long history in evolutionary and ecological research. However, trait data are often scattered and standardised terminology that transcends taxonomic and biogeographical context are generally missing. As part of the development of a global trait database of marine species, we collated trait info...

A major historical challenge for the management of anthropogenic introductions of species has been the absence of a globally standardised system for species nomenclature. For over a decade, the World Register of Marine Species (WoRMS) has provided a taxonomically authoritative classification and designation of the currently accepted names for all k...

The Flanders Marine Institute (VLIZ) is responsible for the set-up of the LifeWatch Taxonomic Backbone (LW-TaxBB), as a central part of the European LifeWatch Infrastructure. The LW-TaxBB aims to (virtually) bring together different component databases and data systems, all of them related to taxonomy, biogeography, ecology, genetics and literature...

Describing species patterns and their underlying processes are essential to assessing the status and future evolution of marine ecosystems. This effort requires biological information on functional and structural species traits, such as feeding ecology, body size, reproduction, and life history. Basic trait information was already available within...

The World Register of marine Cave Species (WoRCS) constitutes a Thematic Species Database of the World Register of Marine Species (WoRMS). It was launched in 2016 by 8 founding Thematic Editors and the WoRMS Data Management Team with the aim to create a comprehensive taxonomic and ecological database of species known from marine caves and anchialin...

The World Register of Marine Species (WoRMS) celebrated its 10th anniversary in 2017. WoRMS is a unique database: there is no comparable global database for marine species, which is driven by a large, global expert community, is supported by a Data Management Team and can rely on a permanent host institute, dedicated to keeping WoRMS online. Over t...

The World Register of Marine Species aims to provide the most authoritative list of names of all marine species, ever published through a freely available online portal. In 2017, WoRMS celebrated its 10 th anniversary. This was an excellent opportunity to both look backward and forward, by analyzing how the system has grown, how it is used and how...

The World Register of Marine species (WoRMS) has been established for a decade. The early history of the database involved compilation of existing global and regional species registers. This aggregation, combined with changes to data types and the changing needs of WoRMS users, has resulted in an evolution of data-entry consistency over time. With...

The importance of describing species patterns and the underlying processes explaining these patterns is essential to assess the status and future evolution of marine ecosystems. This requires biological information on functional and structural species traits such as feeding ecology, body size, reproduction, life history, etc. To accommodate this ne...

As reservoirs of sponge diversity, marine caves have attracted the interest of sponge researchers from around the world at an early stage. The need to compile all the existing largely scattered information on the sponge diversity of this unique ecosystem has been recently recognized and some regional overviews came out. The World Register of marine...

Scientific exploration of marine cave environments and anchialine ecosystems over recent decades has led to outstanding discoveries of novel taxa, increasing our knowledge of biodiversity. However, biological research on underwater caves has taken place only in a few areas of the world and relevant information remains fragmented in isolated publica...

The objective of Workpackage 4 of the European Marine Observation and Data network (EMODnet) is to fill spatial and temporal gaps in European marine species occurrence data availability by carrying out data archaeology and rescue activities. To this end, a workshop was organised in the Hellenic Center for Marine Research Crete (HCMR), Heraklion Cre...

The Aphia platform is an infrastructure designed to capture taxonomic and related data and information, and includes an online editing environment. The latter allows easy access to experts so they can update the content of the database in a timely fashion. Aphia is the core platform that underpins the World Register of Marine Species (WoRMS) and it...

This paper reviews the utility and availability of biological and ecological traits for marine species so as to prioritise the development of a world database on marine species traits. In addition, the 'status' of species for conservation, that is, whether they are introduced or invasive, of fishery or aquaculture interest, harmful, or used as an e...

Contextual data collected concurrently with molecular samples are critical to the use of metagenomics in the fields of marine biodiversity, bioinformatics and biotechnology. We present here Marine Microbial Biodiversity, Bioinformatics and Biotechnology (M2B3) standards for " Reporting " and " Serving " data. The M2B3 Reporting Standard (1) describ...

MolluscaBase, which will be a Global Species Database covering all marine, freshwater and terrestrial molluscs, recent and fossil, was launched on February 6-7, 2014 at the Flanders Marine Institute (VLIZ) at Ostende, host institute of the World Register of Marine Species (WoRMS). Currently, the WoRMS database contains more than 44,000 valid, verif...

Recently, calcareous cyst producing dinoflagellates, and especially the species Thoracosphaera heimii, have gained more interest in paleoenvironmental and paleoclimatic studies. This PhD thesis focuses on the stable oxygen isotope composition (d18O) and minor element to calcium ratios (Mg/Ca and Sr/Ca) of T. heimii shells from surface sediments in...
