The current version of this project and its data should be cited as:

Hendrickson, Dean A., and Adam E. Cohen. 2022. Fishes of Texas Project Database (Version 3.0). http://doi.org/10.17603/C3WC70. Accessed (insert date).

Note that you can capture the current citation using your bibliographic data management program (e.g. for Zotero, click the icon for its browser extension, or use the similar metadata capture tool provided by most other major bibliographic management apps).

Details about our versions and citations for all are included below.

Our database is in constant evolution as we continue normalizing, georeferencing, verifying identifications and generally managing the data. We update the website as possible following completion of major tasks and in the table below provide basic tracking of those changes via a versioning system as follows, in reverse chronological order.

Our version naming conventions reflect changes we are continually making to the database structure, website and the data. Major revisions of our data schema, website/database interactions, or additions of other major new features are denoted by a whole number change (ex. 1.00 to 2.00). Addition of data tracks are denoted by single decimal version increments (ex. 1.00 to 1.10). Minor tweaking of the website and minor data edits are indicated by increments at the second decimal level (ex. 1.20 to 1.21). 

We keep archived copies of all old versions of the site and its database. Users wishing to see the most recently retired version of the site and database can go here (coming soon). Users should be aware that this is an exact copy of what was originally on our public (www) site and thus some links may be broken or direct users to what is now the current public version. For older versions of the website and database contact us.

For a quick snapshot of our project's status, users should look at this table, as well as Institutions Contributing Data, and Data Tracks.

NOTES:  This is a major revision of the database and website that introduces the track 3 dataset, which is our largest addition to the database so far (1,592,008 records). 1,554,638 coming from new types of data that are not specimen-based, including citizen science, angler catches, audio records, literature-mined data, molecular data, and researcher, federal and state agency databases. There are 37,370 new specimen-vouchered records as well. All these records are from a now larger geographic scope that includes those parts of Texas’ drainages that are also in neighboring states including Mexico. Many of these new records are provided with geographical coordinates mostly from our data donors directly (see here) so they can be queried on geographic parameters and mapped. In order to display these data and integrate Mexican records into the website we had to also integrate hydrologic units for the Rio Grande in Mexico, which we acquired from Mexico’s National Institute of Statistics and Geography (INEGI), into our map and checklists. Adding so many new records over a larger area caused us to add many new species to our taxonomy and we made taxonomic changes based on recent literature as well (see here). With all of the new records and an updated understanding about species distributions from examination of specimens from earlier data tracks, it was clear we needed to reassess our flagging of records (e.g. suspect and need to examine), that are the basis for our color coding (see here). In a series of expert consensus meetings we examined maps of our data, species by species, to re-determined the color coding of all records in the database. We also re-determinedd native ranges for all species in the database that have at least one georeferenced record in our study area and in the process expanded native ranges beyond our state boundaries into our new larger study area (see here).

Other minor improvements include the following: We identified records from captive populations and added a captive flag and filter. We updated some verbatim data (specimen counts and field numbers) that had inadvertently not been carried over in a previous update. We improved and added new dashboards under the Stats & Conservation tab. We added 5,952 specimen images. Due to the large number of new records with variously constructed unique identifiers and sometimes no unique identifier we changed the way that we construct record identifiers (see here).

NOTES: This version introduces track 2 data to the database, which has now been quality controlled and georeferenced. The update includes many new specimen determinations by FoTX staff based on specimen examinations to both track 1 and 2 datasets. Identified additional suspicious records and identified others that are no longer suspect. We've increased the number of taxa we are recognizing including several subspecies and species that are not formally described and justified those decisions in our documentation. The data have been restructured into collecting events by using an algorithm based on our georeferenced localities and edited dates. Now users can search for all specimen records tied to a single collection event. Event level attachments (locality images, fieldnotes) are now possible. Improved user feedback for user submissions. Fixed several bugs related to mapping tab. Uploaded numerous specimen images and fieldnotes from museum archives. Provide character matrices useful for specimen identification in our "sandbox" experimental area. Edited documentation.

NOTES: It was unofficially available to select users for some months prior to this date. Track 1 data are still not finalized, and lack extensive results from our re-determinations of many species identifications, as well as many locality corrections and additional refinements of georeferencing for many records yet to be incorporated into the online database. Only data records from our own Texas Natural History Collection (TNHC) are available to the general public as data release permissions are pending from all other data donors.
