(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)
Partial migration is common among northern ungulates, typically involving an altitudinal movement for seasonally migratory individuals. The main driving force behind migration is the benefit of an extended period of access ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)
Most cervid populations in Europe and North America are managed through selective harvesting, often with age- and sex-specific quotas, with a large influence on the population growth rate. Less well understood is how ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
Background
Many wingless ectoparasites have a limited capacity for active movement and are therefore primarily dependent on hitchhiking on their hosts for transportation. The distribution of the tick Ixodes ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)
Background: Ticks and tick-borne diseases are increasing in many areas of Europe and North America due to climate change, while land use and the increased abundances of large hosts play a more controversial role. The pattern ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)
Background. The Lévy flight foraging hypothesis predicts a transition from scale-free Lévy walk (LW) to scale-specific Brownian motion (BM) as an animal moves from resource-poor towards resource-rich environment. However, ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
Background
The deer ked (Lipoptena cervi) is an ectoparasite on cervids that has invaded large parts of Norway, Sweden and Finland during recent decades. During their host-seeking flight activity, the adult ...

Background. Understanding the variation in prevalence of Borrelia burgdorferi sensu lato (Lyme Borreliosis Spirochaetes, LBS) and Anaplasma phagocytophilum (causing tick-borne fever in ruminants and human granulocytic ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
Background
Understanding aggregation of ticks on hosts and attachment of life stages to different host species, are central components for understanding tick-borne disease epidemiology. The generalist tick, ...

Background: Climate change can affect the activity and distribution of species, including pathogens and parasites. The densities and distribution range of the sheep tick (Ixodes ricinus) and it’s transmitted pathogens ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
Large herbivore consumption of forage is known to affect vegetation composition and thereby ecosystem functions. It is thus important to understand how diet composition arises as a mixture of individual variation in ...
