High infection intensities, but negligible fitness costs, suggest tolerance of gastrointestinal nematodes in a tropical snake
(Journal article; Peer reviewed, 2015)
We investigated patterns of prevalence and intensity of gastrointestinal nematode infections in a tropical natricine snake, the keelback (Tropidonophis mairii). Ninety-eight per cent of keelbacks were infected with Tanqua ...
Predator-dependent functional response in wolves: from food limitation to surplus killing
(Journal article; Peer reviewed, 2014)
The functional response of a predator describes the change in per capita kill rate to changes in prey density. This response can be influenced by predator densities, giving a predator-dependent functional response. In ...
Sarcoptic mange in the Scandinavian wolf Canis lupus population
(Journal article; Peer reviewed, 2016)
Background: Sarcoptic mange, a parasitic disease caused by the mite Sarcoptes scabiei, is regularly reported on wolves Canis lupus in Scandinavia. We describe the distribution and transmission of this parasite ...

Activity patterns of predator and prey : a simultaneous study of GPS-collared wolves and moose
(Journal article; Peer reviewed, 2011)
We studied the simultaneous activity patterns of a breeding wolf, Canis lupus, pair and five adult moose, Alces alces, cows from April to November 2004 in a wolf territory in southeastern Norway. All study animals were GPS ...
Three approaches to estimate wolf Canis lupus predation rates on moose Alces alces populations
(Peer reviewed, 2008)
Abstract We employed three different methods to estimate predation rates on moose in a newly colonized wolf territory in Norway. In the first two methods, we estimated predation rates based on the difference in calf/cow ...
Building a mechanistic understanding of predation with GPS-based movement data
(Journal article; Peer reviewed, 2010)
Quantifying kill rates and sources of variation in kill rates remains an important challenge in linking predators to their prey. We address current approaches to using GPS-based movement data for quantifying key predation ...
A Migratory Northern Ungulate in the Pursuit of Spring: Jumping or Surfing the Green Wave?
(Journal article; Peer reviewed, 2012)
The forage-maturation hypothesis (FMH) states that herbivores migrate along a phenological gradient of plant development in order to maximize energy intake. Despite strong support for the FMH, the actual relationship ...
Decomposing risk: landscape structure and wolf behavior generate different predation patterns in two sympatric ungulates
(Journal article; Peer reviewed, 2013)
Recolonizing carnivores can have a large impact on the status of wild ungulates, which have often modified their behavior in the absence of predation. Therefore, understanding the dynamics of reestablished predator–prey ...
