Estimation of lifetime reproductive success when reproductive status cannot always be assessed

摘要: The Lifetime Reproductive Success (LRS) of an individual i.e. the number young raised during its lifespan is indicator contribution to future generations and thus a measure fitness. Nevertheless, LRS hard estimate because difficulty keep track outcome each breeding attempt (successful or failed and, if successful, raised). We propose two new methods estimating that takes into account uncertainty about reproductive status when individuals are not detected cannot be assessed. illustrate these using roe deer histories discuss their advantages disadvantages.
