The dispersal of woody plant seeds by livestock has been implicated as one of the causes of woody plant encroachment in semiarid ecosystems worldwide. In the southern Great Plains, United States, cattle are suspected to have increased encroachment of

Management of rangelands has changed substantially over the past few decades; today there is greater emphasis on wildlife management and increased interest in using natural disturbances such as fire to manage rangeland plant and animal communities. T

Eddy covariance measurements were begun in late April 2004 to quantify CO 2 exchange in a perennial C 3 /C 4 grassland on the Edwards Plateau near San Marcos, TX. Objectives were to document how net ecosystem exchange of CO 2 (NEE) and its components

The effects of shrub clearing on surface and subsurface water movement in the Edwards Aquifer region were investigated using two large-scale rainfall simulation plots. Multiple replications of a large (168 mm) rainfall event were applied at an ashe j

We investigate the risk that supplemental feeding of white-tailed deer (Odocoileus virginianus) to improve trophy quality may degrade rangeland through overutilization of forage plants near the feeders. We divided a South Texas ranch into 6 areas (ea

We examined regrowth architecture of 4 species of savanna shrubs following 4 levels of defoliation. Defoliation had little effect on the regrowth architecture of honey mesquite (Prosopis glandulosa), which is rarely browsed by mammalian herbivores. T

Photosynthesis, transpiration, and leaf area distribution were sampled in mature Quercus virginiana and Juniperus ashei trees to determine the impact of leaf position on canopy-level gas exchange, and how gas exchange patterns may affect the successf

Seed longevity of the leguminous shrubs Acacia berlandieri and Leucaenapulverulenta was evaluated under field conditions at the soil surface and at 3–5 cm depth. Abiotic influences on seed longevity and dormancy were investigated by comparing seeds

Preweaning growth data were obtained during 4 yr on 349 Braford-sired calves from Brahman-Hereford F1 first-calf females. These females were allotted to either semiarid rangeland (Uvalde) or humid improved pasture (Overton) as weanlings and to one of

Increased Angora and Spanish goat populations in the Tamaulipan Province of southern Texas and northeast Mexico and the economic importance of white-tailed deer lease hunting in the region has heightened concern as to negative interactions between th
