1. Behavioural aspects of conservation breeding : Red junglefowl (Gallus gallus) as a case study
Sammanfattning : Ett stort antal utrotningshotade djurarter ingår idag i bevarandeprogram världen över. Små populationer hålls då i skyddade miljöer, exempelvis i djurparker, och i många fall är målet att återintroducera djur till naturen. LÄS MER
2. Habitat composition and restocking for conservation of the white-backed woodpecker in Sweden
Sammanfattning : In Sweden, intense human land use, especially forestry, has led to profound changes in the landscape over time, especially within the forest ecosystems. A consequence of this is that several specialist species have become endangered. One group of specialists is the woodpeckers. LÄS MER
3. Conservation, personality and ecology of the European mink (Mustela lutreola)
Sammanfattning : Loss of biodiversity is a growing problem and hence conservation of species is becoming increasingly important. In this dissertation conservation issues related to the critically endangered European mink (Mustela lutreola) are examined in situ (in the wild) and ex situ (in captivity) on both an individual and community level.

4. Social below ground : Life-history and gut microbiome of Damaraland mole-rats
Sammanfattning : Studying the consequences of variation in individual life-histories is vital for our understanding of the evolution of animal societies. In this thesis, I study the ecology and consequences of group living on growth, survival, reproduction, and the gut microbiome of the Damaraland mole-rat (Fukomys damarensis), a subterranean cooperatively breeding mammal.

5. Dynamics of inbreeding and genetic rescue in a small population
Sammanfattning : Isolation at small population size can reduce individual fitness and impede population growth caused by inbreeding and genetic drift (i.e. inbreeding depression). Inbreeding depression can however be circumvented by gene flow from unrelated individuals through masking of recessive deleterious alleles and contribute to population persistence (i. LÄS MER
