Effects of Supraseasonal Drought on Karst Aquatic Communities of the Edwards Plateau
Supraseasonal droughts refer to an unpredictable period of below average precipitation occurring over multiple seasons and are predicted to become more frequent in central Texas under future climate scenarios. The purpose of this study was to opportunistically assess the effects of a supraseasonal …

Microhabitat Temperature Variations and the Post-Burn Response of Vegetation in the Edwards Plateau of Texas
With the increased use of prescribed fires in the Edwards Plateau comes a need for a greater understanding of factors affecting fire temperatures and post-burn vegetational response. In the winter of 1980, a joint study was initiated on the Kerr Wildlife Management Area, near Kerrville, Texas, to …

Life History and Case Building Behaviors of Phylloicus ornatus (Banks) (Trichoptera: Calamoceratidae) In Two Spring Fed Tributaries in the Central Edwards Plateau Bioregion of Texas
… from two springfed first order streams in the Edwards Plateau Bioregion of Texas were studied from January 1998 to November 1999. Field larval, pupal and adult samples and laboratory rearings indicated a multivoltine cycle. First instars differ from late instars in number of labral setae and in …

How Distance from Groundwater Affects the Water Status of Trees at San Marcos Springs
… I monitored several tree species common to the Edwards Plateau of Central Texas (U.S.A.) during the unusually dry summer of 2022. This included measuring predawn and midday water potentials, as well as the stable isotope ratios of hydrogen and oxygen in plant xylem-, soil-, and lake water in …

A Quantitative Analysis of the Geomorphic Agency of the Mud-Nesting Swallows in Central Texas
… straddles the Balcones Escarpment separating the Edwards Plateau from the Blackland Prairies. Swallows were investigated for their geomorphic role on the landscape, specifically, how much sediment is existing at the colonies positioned under fifteen bridges and one parking garage, what is the …

Ecosystem Transformation Across a Changing Social Landscape: Landowner Perceptions and Responses to Woody Plant Encroachment
… a mail survey to private landowners in the Edwards Plateau of Texas, Central Great Plains of Oklahoma, and Flint Hills of Kansas to investigate landowner perceptions and management responses to WPE. First, I assessed landowners’ acceptance of WPE as a function of how they relate to their …

Effects of Prior Defoliation on the Timing of Life Cycle Events and Susceptibility to Natural Enemies of a Host Specific Gall-Former
… on Quercus fusiformis, a live oak endemic to the Edwards Plateau region of central Texas. Comparisons of these patterns document an apparent shift in the timing of B. treatae emergence (Past: Oct.-Dec., Recent: Dec.-Mar.) and survivorship (Past: 0-50%, Recent: 0-13%) in the presence of natural …

Rapid Quantitative Assessment to Assist in Identification of Imperiled Fishes
… compiled for 50 species of fishes within the Edwards Plateau, Chihuahuan Desert, and South Texas Plains ecoregions of Texas. The 50 species represented 12 families of fishes and consisted of narrowly distributed fishes (i.e., occurring in one drainage) and widely-distributed fishes (i.e., …

Composition of the woody plant understory of plateau live oak (Quercus virginiana var fusiformis) clusters in a central Texas savanna
Plateau live oak is thought to act as a nurse plant to other woody species on the Edwards Plateau of central Texas; however, little is known of the nature, extent and duration of this facilitation. In this study, a comprehensive assessment of the composition and abundance of understory woody plants …

Physical and geochemical response in cave drip waters to recent drought, central Texas, USA : implications for drought reconstruction using speleothems
… sites in Inner Space Cavern (IS), a cave on the Edwards Plateau in central Texas, was undertaken to assess the physical and geochemical response of cave drip waters to extreme drought. Drip rate, calcite growth rate, and dripwater geochemistry were monitored before, during, and after the peak of …
