Resource Selection by African Buffalo (Syncerus caffer) in the Caprivi Strip, Namibia
Figure 5. The Caprivi Strip, with home range shown for collar ID 77265, residing in Mudumu area. The home range is represented by a grey outline, with buffalo GPS locations shown inside as fine black points. Blue circles represent pans (ephemereal water sources), and red lines are barriers (either fences, rivers, or roads).
Figure 6. Logistic regression results displayed as a probability surface for occurrence of buffalo, collar ID 77265. Note that the surface can only be considered valid within the home range (grey outline). Red indicates high probability of occurrence, yellow indicates low. White is missing data. The EVI tile used is for January 1-16, 2011, so this represents probability of occurrence during wet season. Resolution is 250 m.
Figure 7. Layers used (coefficients) in probability surface for 77265, January 1-16, 2011. Home range is grey outline, pans are blue circles. Black specks indicate GPS locations. Red lines are barriers, and green is vegetation type and EVI. Resolution = 250 m.
Figure 8. Logistic regression results displayed as a probability surface for occurrence of buffalo, collar ID 77265. Note that the surface can only be considered valid within the home range (grey outline). Red indicates high probability of occurrence, yellow indicates low. White is missing data. The EVI tile used is for June 20 - July 4, 2011, so this represents probability of occurrence during dry season.
Figure 9. Layers used (coefficients) in probability surface for 77265, June 20 - July 4, 2011. Home range is grey outline, pans are blue circles. Black specks indicate GPS locations. Red lines are barriers, and green is vegetation type and EVI. Resolution = 250 m. Note EVI in background is much lighter than January.
