1. Predation and shorebirds: predation management, habitat effects and public opinions
Abstract : Many shorebird populations are rapidly declining and a high nest predation rate is one of the threats facing these populations. Thus, factors that affect predation and how to manage it in an effective way are receiving increased attention. READ MORE

2. Behaviour and life-history responses to chick provisioning under risk of nest predation
Abstract : This thesis examines risk management in breeding Siberian jays (Perisoreus infaustus), which is indigenous to the northern taiga. Parent behaviour and the nest are cryptic. A new nest is built each year. It is placed on spruce or pine branches close to the trunk and well insulated with lichens, feathers and reindeer hair. READ MORE

3. Habitat selection, nest predation and conservation biology in a Black-tailed Godwit (Limosa limosa) population
Abstract : This thesis focuses on a black-tailed godwit (Limosa limosa) population, consisting of 35-40 pairs, that breeds on a grazed shore meadow on SE Gotland, Sweden. The small size of the population makes it more prone to extinction due to chance events, than a larger population.The godwits showed microhabitat preferences when choosing nest sites. READ MORE

5. Population ecology and management of waders breeding on coastal meadows
Abstract : Many wader (Charadrii) populations are declining throughout in Europe, but the underlying causes are often poorly known and diverse. To fully grasp the reasons behind declines in vulnerable wader populations, it is crucial to understand the demography. READ MORE
