Factors Affecting Survival of Attwater's Prairie-Chicken Broods

چکیده
Abstract Annual population changes of most grouse, including the imperiled Attwater's prairie-chicken Tympanuchus cupido attwateri, are driven by annual reproductive success. Previous research identified poor survival chicks as a primary bottleneck for recovery this species. We evaluated relative importance 26 factors in 5 categories (weather and topography, habitat, plant phenology, time site, hen characteristics) on brood to 2 wk posthatch (the period when chick mortality is highest) number per at 6 (when capable independent survival). Factors with support predicting included invertebrate dry mass, ordinal date, an index maximum photosynthetic activity vegetation from multispectral imagery, proportion locations within areas treated suppress red imported fire ants Solenopsis invicta. Broods were likely survive if they hatched between early late May located 1) that ants, 2) where produced intermediate values index, 3) supported high biomass. The surviving was best predicted nonlinear relationship drought during first posthatch, it maximized average indicated moderately depleted soil moisture, but not severe drought. Our finding after hatch had more than did entire emphasizes prairie-chickens. This comprehensive analysis affecting provides valuable information guide management efforts
