1. Cycles of voles, predators, and alternative prey in boreal Sweden
Sammanfattning : Bank voles, grey-sided voles, and field voles had synchronous 3-4 year density cycles with variable amplitudes which averaged about 200-fold in each species. Cycles of vole predators (red fox and Tengmalm's owl), and their (foxes') alternative prey (mountain hare and forest grouse) lagged behind the vole cycles. LÄS MER
2. Aspects of locomotor evolution in the Carnivora (Mammalia)
Sammanfattning : In this thesis, the shape of the distal humerus trochlea is analysed using landmark-based morphometrics and multivariate methods, with the aim of exploring locomotor evolution in carnivorans. Elbow joint morphology is used together with body size and craniodental morphology to characterize past and present carnivorans. LÄS MER
3. Habitat selection and breeding ecology of golden eagles in Sweden
Sammanfattning : The red-listed Golden Eagle (Aquila chrysaetos) population is estimated between 1200-1400 reproductive individuals in Sweden. This population is unusual as eagles predominantly nest in trees unlike most others that prefer cliffs. LÄS MER
