Determine a logical gbif records threshold #7

Closed SanderDevisscher closed 3 years ago

SanderDevisscher commented 3 years ago

In the current climate matching outputs (see future & present - data overlays) contain all species with at least 1 record in the belgian climate zones (Cfa, Cfb & Dfb). A single/low number of record(s) can be an error, fluke, etc.... and can best be excluded from the list.

But a what number do we place the threshold ?

timadriaens commented 3 years ago

OK, I played around a bit with those. My proposal for criterium:

This should leave the following number of species:

Astacopsis gouldi Cfb 713 99

I find it striking though that none of the species occur twice in both climate classifications for Belgium.

timadriaens commented 3 years ago

If we are a bit more severe on the criteria:

=150 records, 20% overlap

current: 14 future: 22 both: 13 species

=200 records, 20% overlap

current: 10 future: 15 both: 9 species

@adrienlatli can you take a look at the above list and tell us if that is workable? Do we want to land at around 30 spp to risk assess or do we go for less?

adrienlatli commented 3 years ago

Great Job Sander thx.

I think 30 spp to risk assess is realizable by Romain. This number could be improve if they find new species in shop but I'm think it's still feasible. I need to present these results to Romain and Etienne and I will come back soon.

@timadriaens : If you can add Romain to Github it's must be usefull :-) (WILLEPUT Romain Romain.Willeput@ulb.be)

timadriaens commented 3 years ago

ok! we need his github name for that

timadriaens commented 3 years ago

@adrienlatli OK, calculating back from those 30 species I propose the following cut-offs (it appears the total number of records on gbif is more limiting than the degree of KG overlap):

This leaves exactly 30 species.

species

@SanderDevisscher can you rerun using those selection criteria?

SanderDevisscher commented 3 years ago

ok! we need his github name for that

@adrienlatli can you provide his github username ?
