(2013-01-18)Africanized honey bees (AHB) are a hybrid between African and European honey bees (EHB). Compared to the EHB, AHB exhibit more intense, defensive behaviors but nevertheless provide the same important ecosystem service--p ...
-
(2017-12-11)Full waveform (FW) and photon counting LiDAR (PCL) data have garnered greater attention due to increasing data availability, a wealth of information they contain and promising prospects for large scale vegetation mapping. ...
-
(2020-03-30)An essential, natural process of a stream is the movement of sediment. However, the natural balance of sediment transport in a stream is seldom observed as a result of anthropogenic implications. An urbanizing stream can ...
-
(2012-02-14)Although cottonseed is an important source of oil and fiber, the development of cotton embryos has not been investigated as well as development of cotton fiber. The development of cotton embryos in late heart-stage and ...
-
(2015-01-23)This dissertation work explored the application of remote sensing technology for the assessment of forest carbon storage in Mt. Apo Natural Park. Biomass estimation is traditionally conducted using destructive sampling ...
-
(2012-07-16)The majority of biofuels are produced from corn and grain. The drawback to these sources of biofuels is the vast amount of cultivated land needed to produce substantial amounts of biofuel, potentially increasing the price ...
-
(2014-09-29)Perpetual conservation easements have become one the primary tools used for long-term land protection and are credited with helping protect endangered species, preventing habitat fragmentation, maintaining ecosystem functions ...
-
(2017-10-17)The Soil and Water Assessment Tool (SWAT) has been successfully used to predict alterations in streamflow, evapotranspiration and soil water. Previous research suggests that while the hydrologic balance in each watershed ...
-
(2019-09-10)With the removal of fire and increased grazing pressures in savanna ecosystems worldwide, graminoid abundances have decreased while invasive woody shrubs densities have increased. This has contributed to numerous deleterious ...
-
(2014-11-05)Increasing concentrations of greenhouse gases are projected to elevate global surface air temperatures by 1.5 to 4.5 °C by the end of the century, and magnify the intensity and variability of seasonal precipitation ...
-
(2014-01-29)Plantation forestry is central to supplying the global demand for forest products and sustainable production will rely on information regarding the effects of disturbance on soil biogeochemistry. The extent of ecosystem ...
-
(2012-07-16)Woody plant encroachment is a globally-prevalent vegetation change phenomenon that has shifted grass-dominated ecosystems to mixed grass and woody plant matrices over the last century. In the Rio Grande Plains of Texas, ...
-
(2010-07-14)Ranching communities in Texas have long recognized fee hunting as a natural resource with the potential of directly affecting agricultural incomes. Hunting as an industry today, appears to be developing into an economic ...
-
(2010-07-14)To maintain optimal cytosolic Ca2+ concentrations, cells employ three distinct strategies: 1) tightly regulated influx of Ca2+; 2) efficient efflux of Ca2+ from the cell; 3) sequestration of Ca2+ in organelles. Ca2+efflux ...
-
(2013-09-28)With a vast amount of people living in semi-arid to arid environments around the globe, the resource of water is valued very highly. The Carrizo-Wilcox aquifer in SW Texas is a semi-arid zone and was chosen as the site for ...
-
(2016-07-29)Big Bend National Park has some of the most diverse ecosystems and landscapes in the country. Tourists are drawn to the park’s unique biological diversity provided by the park’s natural resources each year. The potential ...
-
(2013-04-29)Junipers and pines exhibit contrasting patterns of growth decline and mortality with climate change-type warming and drought; yet, the underlying physiological mechanisms are not fully understood. Does warming exacerbate ...
-
(2010-07-29)Four major Southern pines, Pinus echinata Mill., P. elliottii Engelm., P. palustris Mill. and P. taeda L. are evolutionarily young and closely related. They have not been intensely researched except P. taeda. In this study ...
-
(2015-08-10)One land condition shown to affect storm runoff/discharge and sediment exports is bare ground. High sediment exports in runoff indicate erosion is taking place within a watershed. Precipitation drives runoff and sediment ...
-
(2011-02-22)This study examined what effects, if any, cultural factors have on conceptual knowledge of evolutionary theory through natural selection. In particular, the study determines if Latino and non-Latino students differ in ...
