INTRODUCTION
The GBIF Secretariat, Denmark
The Global Biodiversity Information Facility
This lecture is presented by Juan C. Bello, Senior Programme Officer for NODES at the GBIF Secretariat in Copenhagen, Denmark.
This is an extensive introduction to biodiversity, biodiversity information and biodiversity informatics. It describes what is considered biodiversity information and its different levels of organization and sources. The challenges identified when dealing with biodiversity data are shown, together with the solutions in place up to the moment.
Some other relevant topics regarding the management of biodiversity information are also tackled, such as data quality or intellectual property rights.

BIODIVERSITY
Biodiversity and Biodiversity Informatics
Biodiversity levels, a caveat
• Genetic variability: refers to the genetic differences that occur within a particular species that can be passed along to offspring.
• Species diversity: refers to the variety of species that occur within a particular area. Collectively, all of the individuals of a particular species in a particular area form a population.
• Community diversity: refers to the associations of species within an area. These associations, also called biological communities, are the living components of ecosystems.
• Landscape/regional diversity: refers to the variety of ecosystems and communities that can be found within the landscape.
Species diversity: refers to the variety of species that occur within a particular area. Collectively, all of the individuals of a particular species in a particular area form a population.
From: After Noss & Cooperrider (1994), Decker et al. (1991) and Riley & Mohr (1994)

Biodiversity and Biodiversity Informatics
Accessibility of biodiversity information
Biodiversity information was/is not easily accessible:
• It is not in digital form
• It is scattered
This is a problem, not just for scientists, but for society

INFORMATION ACCESIBILITY
Biodiversity and Biodiversity Informatics
Biodiversity Information
Where is the information?
In a myriad of places Access hampered Limited used (outside the scientific community) Substitutes sought
Picture of the past?

Biodiversity and Biodiversity Informatics
INFORMATION ACCESIBILITY
Access to scattered sources: a workable solution
It is difficult to integrate data: the GBIF Experience
huge variation in ScientificName, Classification, Country
over 150 million occurrence records integrated
4 versions of Darwin Core and 4 of ABCD
4 standard data provider packages
range of alternatives for content item, e.g. date, makes
integration very hard
![Page 15: II Course on GBIF Node Management Arusha, Tanzania 31 st October and 1 st November 2008 Biodiversity and Biodiversity Informatics Juan C.BELLO Senior Programme.](https://reader035.fdocuments.us/reader035/viewer/2022081519/56649ce15503460f949abc4b/html5/thumbnails/15.jpg)
Biodiversity and Biodiversity Informatics
Unified access, distributed information: common profile + standards (1/3)
A. Common profile:
Each particular database structure is translated into a “profile”, a table with common field list that can be accessed in a uniform manner
B. Standards:Biodiversity Information Standards
www.tdwg.org
PROFILES & STANDARDS
![Page 16: II Course on GBIF Node Management Arusha, Tanzania 31 st October and 1 st November 2008 Biodiversity and Biodiversity Informatics Juan C.BELLO Senior Programme.](https://reader035.fdocuments.us/reader035/viewer/2022081519/56649ce15503460f949abc4b/html5/thumbnails/16.jpg)
Biodiversity and Biodiversity Informatics
Unified access, distributed information: common profile + standards (2/3)
http://www.tdwg.org/standards.html
PROFILES & STANDARDS
• To enable interoperability;
• To avoid the Tower of Babel effect (building isolated, non-communicating data silos);
• Without standards, sharing data between any two databases would require mapping their schemas (many to many);
• A federation schema requires mapping just once (many to one).

Biodiversity and Biodiversity Informatics
PROFILES & STANDARDS
“a standard designed to facilitate the exchange of information about the geographic occurrence of species and the existence of specimens
in collections”
http://wiki.tdwg.org/DarwinCore/
Darwin Core (DwC)
• Provides a flat set of 46 elements grouped in 7 element sets (record-level, taxonomic, identification, locality, collecting event, biological, reference).
• Provides an extension mechanism to allow further, more specialised element sets to be included (geospatial, curatorial, palaeontological, interaction).
• Best used with simple data that fits into a flat spreadsheet.

Biodiversity and Biodiversity Informatics
PROFILES & STANDARDS
“ABCD Schema is a common data specification for biological collection units, including living and preserved specimens, along with
field observations that did not produce voucher specimens. It is intended to support the exchange and integration of detailed primary
collection and observation data. ”
ABCD
• Originally developed under EU BioCASE project (The Biological Collections Access Service for Europe);
• More complex and comprehensive than DwC;• Nearly 1200 concepts in hierarchical structure supporting repeating
elements and complex types;• DwC and ABCD strive for compatibility: it is possible to map ABCD
elements to their DwC equivalents;• Best used for detailed records with, e.g., multiple identifications or
linked images.

Biodiversity and Biodiversity Informatics
NAMES & TAXONOMIC CONCEPTS
Data integration & interoperability: taxonomic concepts
Access to information: one collection /source Access to information: multiple collections
Biodiversity information users must confront an impediment: one species may be addressed under different names; a name may refer to different species or concepts of a species.
Primary data
Names
Concepts
Information, as it is currently presented only make sense to the specialist

Biodiversity and Biodiversity Informatics
Accessibility of biodiversity information: names, taxonomic views
• Taxonomic views of names provide names arranged according to a specific taxonomic treatment:
Species 2000: http://www.sp2000.org
ITIS: http://www.itis.usda.gov
UBIO: http:/www.ubio.org
• Many others at regional level, e.g.:Index Synonymique de la Flore de France: http://www.dijon.inra.fr/flore-france/
Anthos (flora of Spain): http://www.programanthos.org/

LITERATURE
LiteratureAs a way to enable access the scientific knowledge.“digital libraries” are becoming a common thing:
One of the firs and biggest:Bibliothèque numérique dela Bibliothèque nationale de France:http://gallica.bnf.fr/
Developments in the area:project to join current initiatives by big institutions: The “Biodiversity Heritage Library” projecthttp://www.bhl.org/
The challenge is open access and, again integration

Biodiversity and Biodiversity Informatics
CHALLENGES
• To cross the digital divide
From paper to digital formMoving our science into e-taxonomy(Maybe from digital to paper too!)
•To integrate resources
within and between areas (names-specimens-species-literature)
• To cross the science - society divide
make science knowledge accessible to society and used to make sound political decisions
![Page 30: II Course on GBIF Node Management Arusha, Tanzania 31 st October and 1 st November 2008 Biodiversity and Biodiversity Informatics Juan C.BELLO Senior Programme.](https://reader035.fdocuments.us/reader035/viewer/2022081519/56649ce15503460f949abc4b/html5/thumbnails/30.jpg)
CONCLUSIONS
Biodiversity and Biodiversity Informatics
• Any collection (resource) is an important piece to
understand biodiversity on Earth ant multiple levels
• The way ahead is to provide that “understanding of
biodiversity” to the society
• Data providers (collection managers, database scientific
administrators, project data managers,…)are in the best
situation to make the best use of data.
