Appendix A. Model selection for the probability of (Table A1) female survival and (Table A2) paturation, and for the probability of (Table A3) offspring survival over summer and (Table A4) winter.

TABLE A1. Model selection for the influence of female characteristics and environmental conditions on the probability of survival in adult female mountain goats, at Caw Ridge, Alberta (1990–2007). Best models are shown in bold and equivalent models (ΔQICu ≤ 2) in italic.

TableA1

Notes: NP = number of parameters. I = intercept. NPI = North Pacific Index the current year. NDVI = Normalized Difference Vegetation Index the current year. Age = female age the previous year in 3 categories: young (3 to 6 years), prime-aged (7 to 9 years), and old (10 years and older). Status = reproductive status the previous year in 2 categories: breeding and nonbreeding females. Density = total population density the previous year. Quality = index of female quality, with high values representing individuals with high body mass and social rank.


 

TABLE A2. Model selection for the influence of female characteristics and environmental conditions on the probability of parturition in adult female mountain goats, at Caw Ridge, Alberta (1990–2007). Best models are shown in bold and equivalent models (ΔQICu ≤ 2) in italic.

TableA2

Notes: NP = number of parameters. I = intercept. NPI = North Pacific Index the current year. NDVI = Normalized Difference Vegetation Index the current year. Age = female age the previous year in 3 categories: young (3 to 6 years), prime-aged (7 to 9 years), and old (10 years and older). Status = reproductive status the previous year in 2 categories: breeding and nonbreeding females. Density = total population density the previous year. Quality = index of female quality, with high values representing individuals with high body mass and social rank.


 

TABLE A3. Model selection for the influence of female characteristics and environmental conditions on the probability that the offspring of a female will survive over summer, in mountain goats, at Caw Ridge, Alberta (1990–2007). Best models are shown in bold and equivalent models (ΔQICu ≤ 2) in italic.
