Timing of fledging and post-fledging survival probability in barn owls (Tyto alba)
, 2023 Der Moment des Ausfliegens und die frühe Zeit nach dem Ausfliegen sind entscheidende Phasen im Leben eines Jungvogels, die durch eine hohe Sterblichkeitsrate gekennzeichnet sind, welche erhebliche Auswirkungen auf die Populationsdynamik haben kann.

Separating the Costs and Benefits of Employee Turnover: A Theory‐Driven Method and Applications
Industrial Relations: A Journal of Economy and Society, EarlyView.ABSTRACT Employee turnover is costly, but it may also benefit performance through improving job‐worker match quality. Existing studies estimate only the net turnover‐performance relationship, ignoring benefits and biasing cost estimates. We develop a theory‐driven method that separately identifies operational costs and match‐quality benefits of ...

Arthropod Effect on Post-fledging Survival of the Dickcissel (Spiza americana)
, 2016 The post-fledging period, the time period after leaving the nest to parental independence, is an important yet understudied portion of grassland bird lifecycles which may help determine how bird populations respond to habitat management.

Post-fledging behaviour and dispersal in American dippers
, 2006 The post-fledging period is a critical stage in the avian life cycle since foraging skill development and dispersal decisions are known to influence survival and reproductive success. I studied parental care, begging patterns and natal dispersal decisions in fledgling American dippers (Cinclus mexicanus). In contrast to studies of nestlings, begging by
