Biodiversity Data

Expectations from an ‘Ideal’ Biodiversity Information System
• Integration of data on different systematic groups
• Integration of heterogeneous databases
• Integration of data on different kinds of objects (species, specimens, geographical localities…)
• Efficient tools for data analysis, modelling and visualization
• Accessibility through the Internet
• User-friendly interface
The Diversity of Biodiversity Data(Examples from the VI ICSEB conference on
“Biodiversity in the information age”)
Ecosystems
Conservation
Morphometrics
Biogeography
Collections
Life history strategies
Genes
Genetics
Global change
Butterflies
Morphology
PhylogenyEcology
Taxonomy
Species
Objects of Biodiversity Data
• Taxonomic objects (species, genera..)
• ‘Unit-level’ objects (specimens, observations)
• Geographical objects (sites, regions, grid cells..)
(for plant species: life form, flower color, conservation status..)
(collector name, collection date, stage, sex, age, length..)
(rainfall, temperature, elevation, soil, land-use, nature reserves..)
Taxonomical links (species names)Geographical links (geographic coordinates)
