Taxonomic Databases

Specialized digital repositories that organize and store biological classification data, enabling the systematic documentation and retrieval of species information and their evolutionary relationships.

Overview

Taxonomic databases serve as crucial digital infrastructures for organizing and maintaining biological classification systems. These specialized repositories form the backbone of modern biological classification efforts, providing structured storage and access to information about species, their relationships, and their hierarchical organization in the tree of life.

Core Components

A taxonomic database typically contains:

  • Scientific names and nomenclature
  • Hierarchical classification data
  • phylogenetic relationships
  • Species descriptions and characteristics
  • Geographic distribution information
  • taxonomic keys and identification tools

Major Systems

Global Systems

Several major taxonomic databases serve the international scientific community:

  1. Catalogue of Life (CoL)

    • Comprehensive global index of species
    • Integration of multiple taxonomic databases
    • Standard reference for biodiversity research
  2. Integrated Taxonomic Information System (ITIS)

    • Partnership of federal agencies and international organizations
    • Focus on North American species
    • Reliable taxonomic information source

Specialized Databases

Domain-specific databases focus on particular groups:

  • GenBank - Genetic sequence database
  • WoRMS - World Register of Marine Species
  • GBIF - Global Biodiversity Information Facility

Technical Implementation

Data Structure

Taxonomic databases employ sophisticated data models to represent:

Interoperability

Modern taxonomic databases emphasize:

  • Standard data formats (Darwin Core)
  • API access
  • data integration capabilities
  • Cross-reference mechanisms
