  5. 5. e-Infrastructures e-Infrastructures enable researchers in different locations across the world to collaborate in the context of their home institutions or in national or multinational scientific initiatives. They can work together by having shared access to unique or distributed scientific facilities (including data, instruments, computing and communications)*.” Examples: *Belief, OpenAire, i-Marine, EU-Brazil OpenBio,
  6. 6. e-Infrastructures • Data e-Infrastructure: an e-Infrastructure promoting data sharing and consumption. Addresses the needs of the research activity performed by a certain community. • Computational e-Infrastructure: an e-Infrastructures offering computational resources distributed in a network environment. Uses Cloud computing to execute calculations with a large number of connected computers. Offers collaboration facilities for scientists to share experimental results.
  7. 7. Virtual Research Environments Virtual Research Environments: virtual organizations of communities of researchers for helping them collaborating. • Define sub-communities inside an e-Infrastructure; • Allow temporary dedicated assignment of computational, storage, and data resources to a group of people; • Very important in fields where research is carried out in several teams which span institutions and countries. e-Infrastructure VRE VRE VRE

  9. 9. Outline i-Marine is both a Data and a Computational e-Infrastructure (Hybrid Data Infrastructure) • Used by several Projects: i-Marine, EUBrazil OpenBio, ENVRI, BlueBRIDGE; • Implements the notion of e-Infrastructure as-a-Service: it offers on demand access to data management services and computational facilities; • Hosts several VREs for Fisheries Managers, Biologists, Statisticians…and Students.

  16. 16. Biodiversity Data • Taxonomies • In biology, a taxon (plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. • Introduced by Linnaeus's system in Systema Naturae (10th edition, 1758). • A taxon is usually known by a particular name and given a particular ranking, especially if (and when) it is accepted or becomes established • An accepted taxon is given a formal scientific name, according to nomenclature codes, e.g. Gadus morhua (Linnaeus, 1758)* • A "good" or "useful" taxon is one that reflects evolutionary relationships * More on scientific names here:

  19. 19. Biodiversity Data Providers i-Marine hosts biodiversity datasets coming from several data providers: • Some are remotely accessed and are maintained by the respective owners; • Other ones are resident in the e-Infrastructure. Currently, the accessible datasets are: • Catalogue of Life (CoL), • Global Biodiversity Information Facility (GBIF), • Integrated Taxonomic Information System (ITIS), • Interim Register of Marine and Nonmarine Genera (IRMNG), • Ocean Biogeographic Information System (OBIS), • World Register of Marine Species (WoRMS), • World Register of Deep-Sea Species ( WoRDSS ). Some data providers are collectors of other data providers, but the alignment is not guaranteed! The datasets allow to retrieve: • Occurrence points (presence points or specimen) • Taxa names

  27. 27. OGC Standards Some standards: Web Maps Service (WMS): XML-based protocol that allows to display the datasets on an interactive map viewer Web Coverage Service (WCS): XML-based representation of space-time varying phenomena (especially used for raster maps) Web Features Service (WFS): XML-based representation for discrete geospatial features (especially used for polygonal maps) The Open Geospatial Consortium (OGC) is an international organization involving more than 400 organizations. Promotes the development and implementation of standards to describe geospatial data content and processing.

FAO stock assessment process has been imported on the D4Science e-Infrastructure with several benefits. Standard R environment • Sequential execution • For R experts only • Requires 30 days D4Science • Cloud computation • Web interface available for non experts • Requires 15h and 20 min • Produces the same output as the R process • 97.8% processing time reduction Output snippet

  48. 48. Why rare species? • Biological and evolutionary investigations • Fisheries management policies and conservation • Vulnerable Marine Ecosystems • Key role in affecting biodiversity richness • Indicators of degradation for aquatic ecosystems
  49. 49. Detecting rare species • How to build a reliable distribution from few observations? • How to account for absence locations? • Is there any approach for rare species?
  50. 50. Data quality For rare species, data quality is fundamental: • Reliable presence data • Reliable absence locations • High quality environmental features • Non-noisy environmental features
  51. 51. Tools From i-Marine: • Retrieve presence data • Generate absence data • Get environmental data • Model, adjust data and produce maps • Share results

  60. 60. Conclusions • Using data quality enhancement produces high performance distribution • A presence/absence ANN combines these data • Biological, observation and expert evidence confirm the prediction by the ANN
  61. 61. Summary: modelling rare species distributions 1. Retrieve high quality presence locations by relying on the metadata of the records, 2. Use expert knowledge or an expert system to detect absence locations. Select absence locations as widespread as possible, 3. Select a number of environmental characteristics correlated to the species presence, 4. Use MaxEnt to filter the environmental characteristics that are really important with respect to the presence points, 5. Train an Artificial Neural Network on presence and absence locations and select the best learning topology, 6. Project the ANN at global scale, using the a resolution equal to the maximum in the environmental features, 7. Train a MaxEnt model as comparison system.
  62. 62. Coelacanth (Latimeria chalumnae, Smith 1939) Coelacanths were thought to have gone extinct in the Late Cretaceous, but were rediscovered in 1938 off the coast of South Africa. Its current form is closely related to its form 400 million years ago. It is related to lungfishes and tetrapods.
