Re: Relating Biotopes to species in R6

Hello,

Can someone tell me whether, using R6, there is a way of reporting the biotopes associated with specific species occurring at different sites. This facility was available in Recorder 3 and was useful to show species preferences. At a time when the realisation of the importance of recording the activities of species along with habitat details for those working in the fields of biodiversity and conservation it seems that R6 makes this objective more difficult to achieve or am I wrong?

Re: Relating Biotopes to species in R6

Hi Harold, yes it is possible to report on the biotopes you have recorded in Recorder 6. You can use the Report Wizard where you can report on either taxa or biotopes or both; or it is possible to create a custom report using XML Reports.

Re: Relating Biotopes to species in R6

Thanks Charles. I have now found the route to reporting both biotopes and taxa in the same report. However, the display of the results shows either the biotope term or the taxa but never both together on the same row under their respective columns. Another problem is that all species appear in the results although a filter for "taxon common name is equal to ...." was applied. For some reason when selecting "all information about a place" the complex filter does not always show the biotope terms under available fields. Has anyone encountered thes difficulties and found a solution?  Harold

Re: Relating Biotopes to species in R6

Hi Charles,

Can I add to Harold's query, as I've heard several instances now where there's confusion about this (including my own).  What Harold is trying to do is determine which taxa occur in specific biotopes.  When using the report wizard, it is possible to generate a report about biotopes, but the Taxon fields don't appear in this, which means, for instance, if you have a biotope of woodland, it appears to be impossible to generate a list of taxa that occur in woodland.  Similarly, the biotope fields don't appear when you're generating a taxon report.  It is possible in the wizard to list measurements and filter for specific features of the site, but this generally isn't associated with a specific taxon.  For instance, a particular woodlouse might be found in a wall in a woodland.  The wall and woodland might be topographical features listed on the site record, but there is apparently no way to state which of these features the taxon was located.

I've no doubt that, as this is such a fundamental analytical tool in zoology, it's possible to do, but I can't work out how to do it.  Hope you (or someone) can help.

Re: Relating Biotopes to species in R6

As far I know, you can't actually directly associate a biotope with a taxon occurrence. Furthermore you can't record a taxon occurrence within a biotope. What you can record are samples (i.e., a sample area) that contain both taxa and biotopes.

So I think what you're after is a way of returning the taxon occurrences of all samples that contain a specified biotope.

I don't think the report wizard is sophisticated enough to do this, although it does sound like a very useful query. Luckily it can quite easily be added to Recorder via XML Reports. Hopefully Sarah is reading this and she can add it to the list of XML Reports to be built into Recorder. Do you have any specific requirements that aren't mentioned in your post or Harold's?

Re: Relating Biotopes to species in R6

Actually, although it's not there at the moment, the Report Wizard could quite easily be persuaded to provide an "Associated Biotope" attribute for taxon reports. Sarah, another one to add to the list!

Re: Relating Biotopes to species in R6

Could the Report Wizard filter be persuaded to filter on a specified biotope and thus return all associated occurrences; i.e., occurrences that fall under the same sample as the biotope?

Re: Relating Biotopes to species in R6

I am pleased to know that I haven't missed anything that is already available in R6 to provide the information I need. Actually, the analysis which I most often need to perform is to find out the range and frequency of Biotopes recorded as being associated with a given taxa. I look forward to something becoming available soon. There is a posible problem. When several taxa are recorded from one localty, biotope information may have only been recorded for a single taxa and not necessarily to all the listed species for the locality. Harold

Re: Relating Biotopes to species in R6

So if I've read you correctly, you would like a report that returns all records for a specified location that contains a specified biotope?

Re: Relating Biotopes to species in R6

Sorry that I seem to be confusing the issue. To be specific I would like to know all the biotopes (BTO Habitat Codes) associated with records of Corn Bunting. The locations are not required for such an analysis.

The reason for mentioning locations is that when one opens a survey and selects an event location and field observations a list of species is shown followed by one or more biotopes. It is not clear which species is associated with which biotope. My concern was, could this influence the analysis of species and biotopes?

Re: Relating Biotopes to species in R6

When you say you'd like all biotopes associated with records of Corn Bunting, what do you mean, precisely, by "associated"?

Re: Relating Biotopes to species in R6

In an ideal world I would like every taxon record to be accompanied by (or associated with) a biotope record. The scientific application would be to obtain a histogram showing the numbers of each category of biotope associated with the records of a given species on the database in order to evaluate a species preferences. Although I may have expressed myself badly I hope that the purpose of my enquiry is now clear.

Re: Relating Biotopes to species in R6

For those interested in this topic I am pleased to say that Mike Weideli has provided an XML report which extracts the data to show the frequency of occurrence of the different biotopes associated with a given taxa.

Re: Relating Biotopes to species in R6

That's good news. There are also going to be many more XML Reports (also made by Mike) in the new version of Recorder. I'm currently testing them.

Re: Relating Biotopes to species in R6

It may be useful to be aware that there are two ways of recording biotope in Recorder.
Firstly, as in all the notes above, as biotope occurrences.
Secondly, they may be recorded as a Designation against a Location.
Each method has its merits in respect of survey vs desktop studies and extraction of statistical information. The latter method has proved of value in an LRC with a strong Site-based emphasis where Local Wildlife Site status and changes over time are closely related to BAP priority habitats and their changes over time.
Our surveyors have yet to be convinced that recording to BAP habitat in the field is a necessary part of their work (Tim Corner of BRERC has useful guides to this) so recording biotope occurrences is not an option for us as there is no named person recording these field observations.
