The short versionLifeGate's visual map of all described species will become an open, connected knowledge system with trait-based faceted search built from AI-assisted literature extraction.

Overview

What this was about

Martin (Freiberg) presented LifeGate's PhyloMap, a zoomable visual map of all ~2.6 million described species with ~5 million synonyms and published phylogenies since about 2000. Overlays expose gaps, for example GBIF coverage missing large parts of Coleoptera, algae and mosses, and IUCN assessments almost absent for arthropods. The goal is to attach traits so users can run a faceted search that narrows to one or two species. Birgitta König-Ries then described a new DFG-funded project in which biologists define identification traits, computer scientists use AI to extract them from the literature using manually annotated ground truth, and experts quality-check the results. It also plans to turn LifeGate from a standalone application into a connected part of the knowledge ecosystem through APIs, shared ontologies and knowledge graphs, and integration with Catalogue of Life and ChecklistBank.

Why it matters. Visualising all known species against aggregator coverage or Red List status makes data gaps obvious. A trait-based identification system built with other infrastructures could serve researchers, collections and the public.

Key ideas

In the room

  • The PhyloMap covers all ~2.6 million described species, ~5 million synonyms and all published phylogenies since about 2000 (mostly molecular).
  • Users can zoom from phylum to species and see phylogeny sources, synonyms, species counts and images.
  • A GBIF overlay shows large gaps (e.g. Coleoptera, algae, mosses), and an IUCN Red List overlay shows arthropods essentially unassessed.
  • Goal: attach traits for faceted search (e.g. leaves ≥15 cm, hairy, yellow corolla, in Australia) that narrows to one or two species.
  • New DFG project: biologists define relevant traits from descriptions and existing trait ontologies; computer scientists with AI support extract them from literature using manually annotated ground truth; experts quality-control; newly detected species feed back in.
  • Existing assets: website, code base, ~25 million photos from ~500,000 species, phylogenies and divergence times.
  • Key gap: LifeGate is largely standalone. Plans are APIs, shared ontologies and knowledge graphs, reuse of others' extraction pipelines, integration with ChecklistBank and Catalogue of Life, and offering its visualisation to other projects such as collections.

Programme abstract

LifeGate: Extending a Global Visual PhyloMap into a Structured Biodiversity Knowledge System

Martin Freiberg, Birgitta König-Ries

LifeGate (https://lifegate.idiv.de/) is a biodiversity information platform centered on the “PhyloMap”, a visual representation of biodiversity that enables exploration of taxa across multiple hierarchical levels of the Tree of Life. Unlike conventional biodiversity portals based mainly on text search, the PhyloMap provides a navigable overview of phylogenetic relationships from kingdoms to species. The platform integrates taxonomy, images, phylogenetic information, and links to biodiversity literature.

A new project aims to transform LifeGate into a structured and interoperable biodiversity knowledge system by converting descriptive taxonomic knowledge into machine-interpretable biodiversity data. We combine ontology-based modeling, biodiversity knowledge graphs, and AI-assisted information extraction workflows. Domain-specific templates and OWL ontologies are being developed to represent morphological, ecological, and taxonomic characteristics and to support semantic integration with infrastructures such as GBIF.

The workflow integrates expert curation with semi-automated extraction from taxonomic literature using natural language processing and large language models. Extracted entities and relationships are validated through ontology constraints before integration into the LifeGate knowledge graph. A major long-term objective is the development of structured, visually supported identification and faceted search workflows derived from taxonomic descriptions and trait information.

This contribution presents the existing PhyloMap and its extension toward structured biodiversity knowledge integrating visualization, semantic interoperability, and AI-assisted curation.
