Experimental Manipulation of Spacing Patterns in the Widely Foraging Lizard Cnemidophorus uniparens

I examined the effect of experimentally increased prey abundance on home range and core area size, overlap, and location, and on levels of aggregation in the widely foraging, unisexual lizard Cnemidophorus uniparens. Food supplementation had no effect on home range size but resulted in a significant... decrease in core area size. Supplemental feeding caused a repositioning of home ranges and core areas. Individuals visiting supplemental food sites (= fed) shifted both home range and core areas toward regions with supplemental food. Lizards not observed visiting the feeding areas (= unfed) tended to move home range and core area locations away from those regions. Overlap of core areas and levels of aggregation also increased for fed animals. Ausführliche Beschreibung Beschreibung ausblenden
