Hi Jeff,

3.6 is looking good. I am looking forward to using new features.

On my world life list in 3.5 it showed 946 species. It would treat a subspecies as a species where the nominate form had not been seen.

On 3.6 it shows 935 species and 12 sub species. Can I amend this?

regards

Hi Mark,

Please give a screen capture of exactly how you are seeing this? How you came about this?

I am assuming you used a Life List Report or some report tab. Let me know all of your settings.

In thinking about this, I did change the reports so that it would count these things separately. I hope I didn't miss this total count.

Let me know please,
Jeff

Hi Jeff,

I have attached header to life list. It shows 935/12.

I have seen 946, this shows correctly on tool bar at bottom of screen.

I have also attached what I think is the problem. I have seen Trunpeter finch. What is Trumpeter finch amantum?

I am using Clements it does not show this as a subspecies in the taxonomy view.

Regards

Mark

Hi Jeff,

I have included a screen capture of my clements taxonomy. It seems that in Clements 2004 Trumpeter finch was assigned to the genus Bucanetes and Rhodopechys.

Rhodopechys had sub species, Bucanetes does not.

I have entered a sub species under Rhodopechys and the nominate form under Bucanetes.

Once corrected this will show a 935/11 species, subspecies split which would be correct.

Could I return to my original question about subspecies not being shown as species where the nominate form has not been seen?

Hi Mark,

Now I am lost as to what problem/question we are trying to solve/answer. Please restate.

Thanks,
Jeff

Hi,

Now the taxanomic issues are resolved the question is this:

Why does the new version seperate species from subspecies in life list counts? If a subspecies is the only form of a species we have seen it should show as a species as shown by the life list counts.

The way it appears,  to get an idea of the total species seen, you have to add the species and subspecies together.

To illustrate I have seen 450 species on my N American list, four of those were subspecies and not the nominate form. The list shows 446 species and four subspecies. Surely on life list counts this should show as 450 species.

Regards

Mark

Thanks for clarifying Mark. Things are a little crazy here right now with the release of 3.6.

Life List Counts are still calculated correctly. However, the Life List report does separate species and subspecies in the title bar count as you have seen. The correct count is still the sum of the two. It indicates how many subspecies you have seen in the selected tax list for the given area (and date range and observer) that you have not seen the species for. However, it correctly counts such sightings towards your life count.

As you can see in the counts at the bottom of your main BD window, the sum of the report numbers equals those at the bottom.

Should it? I really don't remember how I came to this, but it seemed that some folks wanted to know the split and were ok with doing the math.

What do you think?

Mark,

See the discussion in this thread for fixing this issue:

Hi Jeff

I've encountered the same species/subspecies "bug" as Mark in trip (& location) reports.  Any species recorded trinomially (e.g. Red-billed Toucan cuvieri) is counted as a subspecies only, even in cases where it is the only form of the parent species recorded.  For example, the totals (Clements 2005 tax list) on the trip (or location) report for a visit to Ecuador I made a few years ago are 166 species/2 subspecies instead of the correct 168 species/2 subspecies. 

 

I've read the "Total number of entries" thread & take the various points you make there.  However, the species/subspecies situation  gets weirder.  As an experiment, I changed one of the miscounted subspecies (Red-billed Toucan cuvieri) back to the parent form (Red-billed Toucan) & then ran the trip report.  The totals now read 167 species/2 subspecies with the RB Toucan appearing twice, once as Red-billed Toucan & once as Red-billed Toucan cuvieri.  As another experiment, I created a dummy sighting so that my Ecuador trip list now contained 2 RB Toucan subspecies: cuvieri (as before) & inca.  The trip totals now become 166 species/3 subspecies.  In cases such as these, simply adding species to subspecies will not give the correct "species" figure nor is there any other way of obtaining it short of going through the list & looking at the individual entries.

Hi Fred, Yes - I agree. The proposed solution in the other thread would solve this issue.

 I've read the "Total number of entries" thread & take the various points you make there.  However, the species/subspecies situation  gets weirder.  As an experiment, I changed one of the miscounted subspecies (Red-billed Toucan cuvieri) back to the parent form (Red-billed Toucan) & then ran the trip report.  The totals now read 167 species/2 subspecies with the RB Toucan appearing twice, once as Red-billed Toucan & once as Red-billed Toucan cuvieri.  As another experiment, I created a dummy sighting so that my Ecuador trip list now contained 2 RB Toucan subspecies: cuvieri (as before) & inca.  The trip totals now become 166 species/3 subspecies.  In cases such as these, simply adding species to subspecies will not give the correct "species" figure nor is there any other way of obtaining it short of going through the list & looking at the individual entries.

If I read this right, Fred, the solution in the other forum also fixes this. It will give the correct numbers as per my suggestion. If I am missing the point, please attempt to reproduce this by creating a dummy observer and assigning it just a couple test sightings and then explain it to me in those terms.

Thanks,
Jeff

Jeff,

I think we are going in the right direction.

Any trip,life or year list should feature clearly the number of species seen.

I am not sure subspecies are important in this feature. Of course I do remember when we did not have clements and the howls of protest then.

Also remember that the nominate is a taxa too, if we show only other taxa as a subspecies, then that will be inaccurate.

So I think we need on all lists the number of species whatever subspecies they are.

In addition the number of sightings could be useful but not highlighted in the top right hand corner. Perhaps at the end.

Regards

Mark

PS. Keep up the good work.

Hi Jeff

Sorry to have muddied the waters with my comments.  I certainly didn't mean to imply that the proposed solution in the other thread wouldn't solve the problems mentioned, but was merely calling attention to what struck me as interesting peculiarities in the way things worked now. 

 

Re your proposed solution, I would expand it slightly as follows:

1. Number of full species.  (= in Linnean terms the number of separate binomials whether part of a trinomial or not)

2. Number of subspecies (= number of  separate trinomials)

3. Number of "forms"  (= full species + those subspecies not already accounted for in the full species list)

4. Number of sightings

 

Anyway, that's my 2 cents.

 

Regards, Fred

Hi Mark,

Not sure I understand this statement. Please expound.

Thanks,

Hi Fred,

No problem. This is a complex topic and one that I want to get right.

I agree with 1, 2 and 4 above.

Not sure what you mean by #3 or why it is important on any given report. Please explain.

Thanks,
Jeff

Jeff,

I mean that on all life,year or trip lists that no matter how many sub species we have seen they should all point to one species. Hope that clears it up.

Yep - that is what I thought Mark. Just wanted to be sure.
