[tdwg-content] What I learned at the TechnoBioBlitz

Tue Oct 12 04:41:00 CEST 2010

Your human-centered distinctions will likely prove to be useful in certain contexts (quarantine; invasive species watches), but think of birds or insects blown or carried into areas by meteorological events that survive and become established for a season or more, or as curiosities of observation (Ross's gull in Massachusetts).  Range extension is important in climate change research and may have nothing to do with direct human activities outlined below.

Cheers!

I would say that the terms should be established in consultation with those most likely to use them (e.g., as you suggest, distribution analysis, niche modellers, etc.)  For example, it might be useful to distinguish between an organism that was itself introduced, compared to the progeny (or a well-established population) of an intoduced organism. This information can be useful for separating things likely to become established in new localities, vs. things that do not seem to "take" in a novel environment.

The bottom line is really whether or not the location is one which should be used for distribution analysis, niche modelling and similar activities.  There will certainly be many grey areas, but it would be good if software could weed out captive occurrences.

We have examples ranging from animals in zoos, to escaped animals, to intentionally and unintentionally introduced populations, to naturalized populations -- and just about everything in-between.  Where on this spectrum would you draw the line for flagging something as "naturally occurring"?

One addition which we do need to resolve (and which has been suggested in recent months) is to have a flag to indicate whether a record should be considered to show a "natural" occurrence (in distinction from cultivation, botanic gardens, zoos, etc.). This is not so much an issue in a BioBlitz, but is certainly a factor with citizen science recording in general - see the number of zoo animals in the Flickr EOL group.

Robert Stevenson has volunteered to take the lead on preparing a technobioblitz lessons learned document, and though the scope of this document is not yet determined, I think the audience will include bioblitz organizers, software developers, and TDWG as a whole. I hope no one is shy about sharing lessons they think they learned, or suggestions that they have. We can use the bioblitz google group for this discussion, and copy in tdwg-content when our discussion is standards-specific.

To illustrate this need: one of the developers spoke of the design choice between "a simple csv file and a Darwin Core record". But a simple csv file is a legitimate representation of Darwin Core! To be fair to the developer, such a sentence might not have struck me as absurd a year ago, before Remsen said "let's use DwC for the bioblitz".

I  think the lessons learned document should include an on-line catalog of cut-and-pasteable examples covering a variety of use cases, together with a dead simple desciption of DwC, something like "Darwin Core is a collection of terms, together with definitions."

The geo namespace is a well used and supported standard, and records with geo coordinates are automatically mapped by several applications. Since everyone was using GPS  to retrieve their coordinates, we were able to assume WGS-84 as the datum.

If DwC:scientificName isn't self-explanatory enough, a user can look it up, and see that any scientific name is acceptable, at any taxonomic rank, or not having any rank. And once we have a scientific name, higher ranks can be inferred.

But when a transcriber felt it was necessary to include in order to capture data in a particular field sheet, she just added the column to the table. This flexibility of schema is important, and is in harmony with the semantic web.
