Microbial Classification System01:24

Microbial Classification System

163
Classification is the process of organizing organisms into hierarchically inclusive groups based on their phenotypic similarities or evolutionary relationships. A species comprises one or more strains, and closely related species are grouped into genera. Genera are further classified into families, families into orders, orders into classes, and so forth, up to the domain level, which is the broadest taxonomic rank derived from a combination of phenotypic and genotypic data.The nomenclature of...

Area of Science:

  • Marine Biology
  • Biodiversity Informatics
  • Data Science

Background:

  • Marine biota data are fragmented across various sources (literature, repositories, unpublished materials).
  • Data heterogeneity hinders scientific reuse, accessibility, and long-term preservation.
  • Challenges exist in combining and analyzing diverse marine biodiversity datasets.

Purpose of the Study:

  • To introduce CRITTERBASE, a unified data warehouse and portal for marine biota.
  • To address the difficulties in accessing and integrating marine biodiversity information.
  • To facilitate scientific analysis and support marine conservation efforts.

Main Methods:

  • Collation of quality-controlled and taxonomically standardized data (presence/absence, abundance, biomass).
  • Integration of data from diverse sources including literature, online repositories, and unpublished research.
  • Development of an interactive portal with comprehensive metadata and links to primary sources.

Main Results:

  • CRITTERBASE hosts data for 18,644 samples and 3,664 benthic taxa (2,824 species).
  • Data covers Arctic, North Sea, and Antarctic regions, spanning from 1800 to 2014.
  • Includes metadata and links to primary data sources for transparency and traceability.

Conclusions:

  • CRITTERBASE provides a valuable, expanding resource for marine biodiversity research.
  • The portal supports studies on spatio-temporal biodiversity patterns and climate change impacts.
  • Enables evidence-based design of marine protection policies.
