Autor: Greg Levandoski, Duane B. Pool, Arvind O. Panjabi, Alberto Macías-Duarte, Irene Ruvalcaba-Ortega

Publikováno v: Journal of Arid Environments. 156:41-49

Local winter abundance of grassland passerines is highly variable throughout the Chihuahuan Desert among years. The objective of this study is to determine if plant biomass in grasslands and precipitation are predictors of bird abundance in space and

Rapid expansion of croplands in Chihuahua, Mexico threatens declining North American grassland bird species

Autor: Alberto Macías-Duarte, Duane B. Pool, Deanna M. Solhjem, Arvind O. Panjabi

Publikováno v: Biological Conservation. 170:274-281

Grasslands are one of the most imperiled ecosystems worldwide. Conversion to cropland and desertification, including shrub encroachment, are primary factors behind the loss of temperate grasslands across the globe. Governments and conservation organi

Publikováno v: The Wilson Journal of Ornithology. 131:72

We determined the effect of the seasonal distribution of summer rainfall and associated seasonal changes in vegetation on the timing of reproduction and reproductive success of the Rufous-winged Sparrow (Peucaea carpalis) in the plains of central Son

Prediction of senescent rangeland canopy structural attributes with airborne hyperspectral imagery

Autor: Duane B. Pool, Rebecca L. Phillips, Mark West, Brad Rundquist, Nicanor Z. Saliendra

Publikováno v: GIScience & Remote Sensing. 50:133-153

Canopy structural and chemical data are needed for senescent, mixed-grass prairie landscapes in autumn; yet data-driven models are lacking for rangelands dominated by non-photosynthetically active vegetation (NPV). We report how field data and aerial
