11. Genetic and environmental factors influencing growth and survival in willow tits, Parus montanus
Sammanfattning : This thesis concerns with the relationship between genetic and environmental attributes and their influence on offspring growth and survival in willow tits (Parus montanus). It also investigates the occurrence of directional or stabilising selection on body size during different life stages or times of the year. LÄS MER
12. A new perspective on avian phylogeny - a study based on mitochondrial genomes
Sammanfattning : The Class Aves (birds) is generally divided into two main groups - the Palaeognathae and the Neognathae. Paleognathous birds are the flightless ratites and the tinamous, while Neognathae include all other extant birds (more than 9,000 species). LÄS MER
13. Avian Malaria and Related Blood Parasites: Molecular Diversity, Ecology and Evolution
Sammanfattning : Malaria-like parasites consist of a large group of species that infects primates, rodents, bats, lizard and birds. I have focused on parasites from the genera Haemoproteus, Plasmodium and Leucocytozoon that are infecting birds. LÄS MER
14. Feathers by day, membranes by night - Aerodynamic performance in bird and bat flight
Sammanfattning : The efficiency and performance of a flying animal is directly related to the aerodynamics around its body and flapping wings. Here, I have developed methods for quantifying the wake dynamics around a flying animal. The results are used to estimate the aerodynamic performance of flapping flight. LÄS MER
15. Birds in the Flow: Flight Mechanics, Wake Dynamics and Flight Performance
Sammanfattning : I share my fascination of bird flight with many others, and here I summarise my thesis on the subject. This thesis emphasises the mechanics of bird flight by focusing on flight mechanics, wake dynamics and flight performance. LÄS MER
