Texas Plants

Prototype TAMU-BWG projects represent collaborative research that generate WWW-based solutions to various informatics problems, both botanical and computional. A TAMU-BWG Windows 95-based data acquisition system is now in use to take specimen data from local collections, the  S. M. Tracy Herbarium and Biology Department Herbarium, to electronic files. Texas A&M is a national center for biodiversity data on the Grass Family (Poaceae/Gramineae) and our research tends to center on this taxon. Grass-related projects include descriptive and photographic image acquisition, and collaborative distribution/diversity mapping systems for adjacent states (Louisiana, Arkansas, and New Mexico) as well as BONAP Checklist data.

The Herbarium Specimen Browser is designed to allow examination of a database of specimens of Texas plants. It can present a high-level taxonomic overview, detailed specimen lists, and maps showing the distributions of specimens and species by county. The system acts on indexed output files exported from the Tracy Herbarium Management System.  It also has the capability of filtering all displayed information by county, herbarium, and other criteria, allowing examiners to view subsets of of information.  More detail on this system can be found in a paper describing the initial prototype of this system (WWW tools for accessing botanical collections - winner of an AACE student award) presented at the 1997 WebNet World Conference by developer Erich Schneider and a more recent overview  from the proceedings of the Third ACM Conference on Digital Libraries (DL '98).
Data developed for an electronic version of A Checklist of the Vascular Plants of Texas, has been processed to allow keyword search for any text string the might be present in the file and also, using presence or absence codes for different vegetation regions, mapped distributions. Links to access this information on the Texas flora has been inserted into several projects, including WWW treatments of the Chenopodiaceae, the Cactaceae, and the California flora (see "Texas Distribution" links for Texas taxa).
Collaborative work with the Flora of Texas Consortium has produced a prototype WWW-based system to express and develop information on a subset of the Texas flora, taxa with distributions limited to the state. This 'Texas Endemics' system features distribution mapping, diversity mapping, and on-line data modification to create a 'dynamic' data set with options to 'register' those qualified (herbarium personnel) to confirm, refute, or add data.
Another project connected to our membership in the Flora of Texas Consortium involves 'demonstration' prototypes for WWW herbarium data expression via merger of specimen records from collaborating institutions. These projects, focused on taxa representing Texas Sunflowers (Helianthus - Asteraceae) and selected Texas Grama Grass species (Bouteloua - Poaceae), use color codes to tag source collection.

Texas Arthropods

The Texas A&M University Insect Collection (TAMUIC) Species Browser is designed to provide access to a database of insect species contained in the TAMUIC. Modeled after the TAMU Herbarium Specimen Browser, the species browser can display overviews of higher classification, detailed species lists, and generalized holdings information for approximately 30,000 arthropod species (mostly insects) representing about 95% of the identified species held in the Texas A&M University Insect Collection

Libellula vibrans - male
The dragonflies and damselflies of Texas is a collaborative project of Texas entomologists designed to provide access to distribution data on the Texas species of the insect order Odonata. All damselfly species known to occur in Texas are listed and links are provided to county-level distribution maps. The system also provides mapped visualization of species diversity for a given family or genus and county-level listings (click on the county) from diversity maps. A similar system is available for a selected number of the most common species of Texas dragonflies. 
Texas Vertebrates
Digital checklists of the amphibians and reptiles of each county in Texas were prepared by James R. Dixon and R. Kathryn Vaughan, based upon information from Amphibians and Reptiles of Texas, by J. R. Dixon (1987, Texas A&M University Press), and from new, documented records that have been reported since the book was published.
