Sex- and age-biased mortality in wild Grey Partridge Perdix perdix populations

Popis výsledku v původním jazyce

Differing reproductive effort, individual qualities and local environmental conditions can lead to uneven mortality risk among individuals within populations, and may result in survival differences according to age and sex. Identification of factors contributing to unequal operational sex ratios has been important for understanding population dynamics and conservation management. In this study, sex- and age-specific mortality was estimated in three wild Grey Partridge populations year round from analysis of radio-tracking data from a total of 168 individuals. Survival days were counted in three periods defined individually for each animal: the pairing period (covey break-up to laying of the first egg); the nesting period (between clutch initiation dateand failure of the last nesting attempt, or the date when chicks were 14 days old); and the covey period (the end of the nesting period or joining a group until covey break-up). Predation was the main cause of mortality.
