摘要: Knowledge of population trends is key importance for sustainable management wildlife and finding reliable cost–effective monitoring methods therefore great interest. In two populations Alpine chamois Rupicapra rupicapra, we collected data on mortality from 12 424 individuals hunted or found dead size based ground counts over a period 28 years. Our study had three aims: 1) investigated if changes in obtained with simple deterministic reconstruction (DPR) approach using hunting natural covary estimates count data. 2) We the performance DPR affected by removal 3) assessed how many years are needed to obtain consistent DPR. results suggested that abundance significantly positively correlated counts. without performed similarly as compared full (hunting mortality). Consistent can be ≥10 data, however, this time span was influenced mean age at death, which turn local regime. suggest perform estimation temporal abundance. The consistence supports use these tools tracking time. However, reliability may vary between influence different regimes must considered correct interpretation results.
