2Major challenges in Biodiversity Science
- How to access Global Biodiversity?
- To see and aggregate data from all round the
world - To synthesise a global view
- To move from description to real analysis
- Ultimately to bring the totality onto the
Internet at a level of abstraction above that
achieved by individual travel and fieldwork - What GBIF calls Digital Biodiversity Science
3Major challenges in Biodiversity Science
- First steps towards a Systems Biology for the
behaviour of global biodiversity - To access an aggregated and synthesised view of
the factual base - To build hypotheses with a sound basis
- To model outcomes based on the hypotheses
- To test the modelled outcomes
4Major challenges in Biodiversity Science
- To a large extent these challenges are convergent
with the goals of the UKe-Science Initiative - indeed, it has been said that analysing global
biodiversity is one of the clearest application
areas - e-Science is about global collaboration in key
areas of science, and the next generation of
infrastructure that will enable it (John Taylor,
02) - We certainly qualify as e-Science
- We certainly need distributed computing, possibly
combining needs for the GRID and for the
Semantic Web.
5Our Vision for the BDWorld GRID
- a distributed problem-solving environment
- giving access to a wide array of the worlds data
sources and analytical tools - providing an integrated and flexible environment
for analysis of global scale patterns in
biodiversity
6Our Vision for the BDWorld GRID
- And suitable for addressing some difficult
Biodiversity questions - - where might a species be expected to occur,
under past, present, or predicted climatic
conditions? - - where should conservation efforts be
concentrated? - - to what extent is biogeography reflected in
phylogeny?
7What are the technical goals of BDWorld?
- Extensible problem solving environment for global
biodiversity analysis - Employ GRID technology because
- (i) Distributed computing
- (ii) Distributed resources
- (iii) Semantic mediation
- Resource location
- Workflow design validation

10Bioclimatic Modelling
- Predicting species distributions under past,
present and future climate scenarios. - Models
- GARP (Genetic Algorithms for Rule-set Production)
- CSM (Climate Space Models)
- Bioclim
11Case Study - Leucaena leucocephala
- Leucaena leucocephala (Lam.) De Wit
- Native of Central America
- Widely introduced around the tropics
- Widely utilised around the globe for
- - Wood
- - Forage
- - Soil enrichment and erosion control
- Regarded as an invasive weed in some areas
12Distribution Data
- Area data from ILDIS
- Point data from private databases and herbaria
Point data of Leucaena leucocephala from Hughes
(1998)
13Example of Modelling
Model of Leucaena leucocephala - for
exploring- in which countries may further
introductions be made? - has the species become
invasive by adapting to new niches?- how will
the distribution change under global warming
scenarios?
14Leucaena leucocephala future predictions
- Hadley Circulation Model - HadCM3 IS92a
ScenarioPopulation rises to 11.3 billion by
2100 and economic growth averages 2.3 per annum
between 1990 and 2100 with a mix of conventional
and renewable energy sources being used. Global
view
15Workflow Design
16Biodiversity Richness Conservation Evaluation
- Which areas represent an optimal conservation
area network? - What compromises can be made in such a selection
process?
17(No Transcript)
18- Phylogenetic Analysis Biogeography
- Does a combined analysis of climate and character
data enhance the robustness of a phylogenetic
analysis?
19A strict consensus of 1024 most parsimonious
trees for Pelargonium
20Some relevant resource types
- Data sources
- Taxonomic Verification and Synonymic Indexing
Species 2000 ITIS Catalogue of Life - Species Information Sources (SISs)
- Species geography Species bank databases
- Descriptive data Species bank databases
- Specimen distribution (BioCASE, AVH,
SpeciesAnalyst, RDG, MBG...DIGIR,ABCD etc) - Geographical
- Boundaries of geographical political units
- Climate surfaces (Hadley, Paul Valdes'
Palaeoclimate Data) - Modelled Climate progressions past and future
- Genetic sequences (EMBL/GenBank, local data)
- Analytic tools
- Biodiversity richness assessment (WorldMap)
- Bioclimatic modelling (Garp, CSM, Bioclim)
- Phylogenetic analysis (Paup, clustalw, etc)
21What does this mean for data management - data
sets?
- Functionality and integrity
- Accurate access by taxonomy
- Synonymic indexing in taxonomic verification
systems - Accurate identification and names in other data
sets - Accurate access by geographical distribution
- Accurate geospatial data for specimen and
observational datasets - Also a role for political units in synthetic
datasets - Accurate access via metadata and semantic
mediation - Semantic inference using metadata and ontology
22What does this mean for data management - systems?
- Global Connectivity
- Need for physical connectivity
- WWW, GRID, Semantic Web..
- Need for Semantic Standards
- TDWG (IUBS Taxonomic Databases Working Group)
- GBIF
- Need for generic solutions to resource location,
metadata and packaging of biodiversity objects.
