Overall statistics page

[wardappeltans]

It would be helpful to have a single page with an overview of all sorts of statistics (generated dynamically). React to this issue, by proposing the items that you would like to see on such a webpage.

Number of records -by year -up to species level -by higher classification (ideally by EOV in the future) Number of datasets Number of marine species Number of data providers Number of nodes ...

[JohnNichollsTCD]

A useful statistic would be for a "From" and "To" for the eventDate, showing the period of activity.

percent of WoRMS marine taxa that have OBIS occurrence records - perhaps by major groups as there is a certain bias to 'big' creatures

Currency of data ie the top 1% are so many years older than today - a measure of data suitable for any rapid changes or management purposes. Hopefully over time this becomes a smaller number

Coverage by depth range - a metric of deep data and how that is improving - something that is not obvious otherwise.

All stats downloadable as a data matrix csv for people to remap, graph, use in teaching etc.

ES50 per cell [if possible with an indication of SE or 95%CL]

Percent (or number) of species unique to the cell (singletons) [an index or rarity]

The ratio of species to sum of the number of Phyla+Classes+Orders [an index of phylogenetic diversity]

Number of threatened species (IUCN have 3 categories +extinct) present.

Number of species known to be human-introduced present

Number of food species present (as listed by FAO statistics?)

Number of records for higher taxon: Pisces, Crustacea, Mollusca, Echinodermata, Annelida, Cnidaria, Porifera, Other [or see more detailed list below]

Number of species per higher taxon: Mammals (cetaceans, others), Birds, Reptiles (snakes, turtles), Pisces (boney, cartilaginous, other), Tunicata, Crustacea (peracarids, decapods, copepods, other), Mollusca (gastropods, bivalves, cephalopods, other), Echinodermata, Annelida, Cnidaria (hydroids, corals, other), Porifera, Algae (macro, micro), Bactera+Archaea, Protozoa (forams, other), Fungi, Other.

The clever Tony Rees invited a userfriendly classification of all life, cross-mapped to the (awful) formal taxonomic classification. It would be worth looking at this because it was very easy to follow.

Consider publishing your first outputs as a paper to demonstrate its presence, comment on findings and data gaps, and invite suggestions for more stats.

sorry I get carried away !
