Influence de la température de l'air et des précipitations sur les tableaux de chassedes tétraoninés
- Effects of air temperature and precipitation on the annual bag of grouse (Tetraoninae)
p. 109-128
Abstract
The present paper deals with the effects of the weather on the annual bag of capercaillie, black grouse, hazel hen and ptarmigan in the canton of Grison (Switzerland). The investigation covers the period 1919-1979, comprising 41, 44 or 59 annual bags, depending on the game species concerned. An assessment was made of air temperature and total precipitation, both being included in the analysis as average values of periods ranging from one to twelve years.
The results showed that under the given general climate the grouse bag was influenced by climatic factors to a remarkably high degree. The effects of the weather during early rearing and the long-term living conditions in winter, in particular, proved to be important key factors in shaping the pattern of abundance dynamics in this central alpine region. The bird species involved showed different sensitivity with respect to the individual climatic factors.
