(Texas A&M University, 2004-11-15)Dysfunctional rangelands lose nutrients and material faster than they capture or create them. The objective of this study was to determine the effectiveness of contour furrows, drill seeding, and aeration treatments in ...
-
Application of NIRS fecal profiling and geostatistics to predict diet quality of African livestock (Texas A&M University, 2005-02-17)Near infrared reflectance spectroscopy (NIRS) and geostatistical techniques were used to predict diet quality of sub-Saharan African (SSA) livestock, and to create cokriged estimated diet quality maps for cattle across a ...
-
(2010-01-16)RENR 405 GIS Environmental Problem Solving is a course offered at Texas A
-
(2010-01-14)Spiranthes parksii Correll is an endemic terrestrial orchid to the Post Oak Savannah of East Texas and is currently listed as federally endangered. The construction of Twin Oaks landfill, approximately 20 km east of College ...
-
(Texas A&M University, 2006-10-30)Ashe Juniper encroachment onto privately owned rangelands in Central Texas has resulted in significant degradation of the ecological condition of these lands, and a subsequent public concern for the hydrologic function, ...
-
(2009-05-15)Increasing interest among restoration ecologists exists in developing strategies that stimulate biotic interactions and promote self-regulation in restored systems. These approaches should target above- and belowground ...
-
(2009-06-02)Loss of wetland habitats across the nation is staggering and continues, especially in urbanizing areas. Thus, wetland restoration has become a priority. However, questions remain regarding system function and biotic ...
-
(Texas A&M University, 2005-02-17)The two most common varieties of the grass Bouteloua curtipendula (Michx.)Torr. in North America use different strategies of clonal growth and have contrasting continental distributions. Variety caespitosa (phalanx form) ...
-
(2009-05-15)Ashe Juniper (Juniperus ashei) is native to the Edwards Plateau in central Texas. In the past 150 years, however, this species has rapidly increased in abundance within its range. Reduced fire frequency and increased ...
-
(Texas A&M University, 2005-08-29)A new zone was added to the existing Livestock Early Warning System (LEWS), which is a subproject of the USAID Global Livestock Collaborative Research Support Program. LEWS uses the PHYGROW model and satellite imagery of ...
-
(Texas A&M University, 2007-09-17)During the growing seasons of 1999 and 2000 five experiments were performed to test growth of the seagrass Halodule beaudettei (shoal-grass) in nursery pond conditions. Sediment oxidation state, sediment source, container ...
-
(Texas A&M University, 2006-08-16)The objective of these studies was to develop near-infrared reflectance spectroscopy calibration equations from diet-fecal pair datasets to predict the diet quality and intake of donkeys. One hundred-forty diet-fecal pair ...
-
(Texas A&M University, 2004-09-30)Grasslands are characterized by recurring disturbances such as fire and grazing occurring against a background of topoedaphic heterogeneity and climatic variability. The result is a complex, multi-scaled disturbance regime, ...
-
(Texas A&M University, 2006-08-16)Vascular plant collections and field data compiled during a one and a half year period for the upper Frio River, Texas, produced a flora that comprises 78 families, 223 genera and 319 species. Vascular plants were collected ...
-
(Texas A&M University, 2008-10-10)The purpose of this study was to identify and quantify estuarine and marine wetland and shore changes circa Galveston Bay Estuary (GBE) from 1995 to 2002 by using aerial photography and GIS mapping techniques. Aerial ...
-
(Texas A&M University, 2006-10-30)Rio Grande wild turkey (RGWT) abundance in portions of the Edwards Plateau has declined steadily since the late 1970s as compared to other areas of the Edwards Plateau where populations have exhibited no trend. The reasons ...
-
(Texas A&M University, 2006-08-16)Plant production and soil microbial biomass (SMB) in grassland ecosystems are linked by flows of carbon (C) and nitrogen (N) between the two groups of organisms. In native mixed grasslands of the southern Great Plains, ...
-
(Texas A&M University, 2005-11-01)This study investigated the use of high resolution satellite imagery in research involving habitat selection, and movement patterns of white-tailed deer and cattle in a semi-arid landscape. Vegetation classification was ...
