Moose effects on soil temperatures, tree canopies, and understory vegetation: a path analysis
Kolstad, Anders Lorentzen; Austrheim, Gunnar; Graae, Bente Jessen; Solberg, Erling Johan; Strimbeck, Richard; Speed, James David Mervyn (Journal article; Peer reviewed, 2018)Large vertebrate herbivores are ubiquitous and increasingly numerous in boreal forests where they are known to influence ecosystems in many ways. However, separating the direct effects of herbivores from their indirect ... -
Moose in our neighborhood: Does perceived hunting risk have cascading effects on tree performance in vicinity of roads and houses?
Mehlhoop, Anne Catriona; Van Moorter, Bram; Rolandsen, Christer Moe; Hagen, Dagmar; Granhus, Aksel; Eriksen, Rune; Ringsby, Thor Harald; Solberg, Erling Johan (Peer reviewed; Journal article, 2022)Like large carnivores, hunters both kill and scare ungulates, and thus might indirectly affect plant performance through trophic cascades. In this study, we hypothesized that intensive hunting and enduring fear of humans ... -
NINAs elgmerkingsprosjekt i gren-seområdet Akershus, Hedmark og Østfold i 2006. Årsrapport
Solberg, Erling Johan; Heim, Morten; Sæther, Bernt-Erik (NINA rapport;, Research report, 2007)Elgmerkingsprosjektet i grenseområdet Akershus, Hedmark og Østfold ble etablert som et del-prosjekt av forskningsprosjektet Optimal høsting i 2002. Hovedmålet var å studere dødelighet og rekrutteringen i en elgbestand som ... -

On fitness and partial migration in a large herbivore – migratory moose have higher reproductive performance than residents
Rolandsen, Christer Moe; Solberg, Erling Johan; Sæther, Bernt-Erik; Van Moorter, Bram; Herfindal, Ivar; Bjørneraas, Kari (Journal article; Peer reviewed, 2016)Partially migratory populations comprise both resident and migratory individuals. Th ese tactics may coexist if their demographic contribution to future generations (i.e. fitness) are equal or vary temporally with environmental ... -
Opposing fitness consequences of habitat use in a harvested moose population
Ofstad, Endre Grüner; Markussen, Stine Svalheim; Sæther, Bernt-Erik; Solberg, Erling Johan; Heim, Morten; Haanes, Hallvard; Røed, Knut; Herfindal, Ivar (Peer reviewed; Journal article, 2020)1. Landscape changes are happening at an unprecedented pace, and together with high levels of wildlife harvesting humans have a large effect on wildlife populations. A thorough knowledge of their combined influence on ... -
Pervasive moose browsing in boreal forests alters successional trajectories by severely suppressing keystone species
Kolstad, Anders Lorentzen; Austrheim, Gunnar; Solberg, Erling Johan; De Vriendt, Laurent; Speed, James David Mervyn (Journal article; Peer reviewed, 2018)Large herbivores can shape young forest stands and determine the successional trajectory of forested ecosystems by selectively browsing palatable species at the sapling stage. Moose (Alces alces) is the dominant vertebrate ... -
Rogn, osp og selje-Har de en framtid i norsk natur?
Solberg, Erling Johan; Myking, Tor; Austrheim, Gunnar; Bøhler, Fredrik; Eriksen, Rune; Speed, James David Mervyn; Astrup, Rasmus Andreas (NINA rapport;806, Research report, 2012)Rogn, osp og selje finnes i alle deler av landet, men med varierende tettheter. Ospa er mest vanlig i kystnære områder i sørøst-Norge, mens rogn og selje er mere jevnt fordelt over hele landet. Artene er særmerket av kort ... -
Spatial and Temporal Variation in Moose- (Alces alces) Road Crossings
Fliflet, Henrik Rasmussen (Master thesis, 2012)This study examined what separates a crossing site from an available crossing site and investigate when and where roads are more likely to be crossed by moose (Alces alces). Five seasonal models for two sexes were selected ... -
Spatio-temporal variation in large herbivore pressure in Norway during 1949-1999: has decreased grazing by livestock been countered by increased browsing by cervids?
Austrheim, Gunnar; Solberg, Erling Johan; Mysterud, Atle (Journal article; Peer reviewed, 2011)During recent decades, rough livestock grazing has decreased markedly on unimproved land (i.e. natural and seminatural habitats) across most of Europe, whilst the number of wild cervids has increased. However, we still ... -
Use, selection, and home range properties: complex patterns of individual habitat utilization
Ofstad, Endre Grüner; Herfindal, Ivar; Solberg, Erling Johan; Heim, Morten; Rolandsen, Christer Moe; Sæther, Bernt-Erik (Journal article; Peer reviewed, 2019)Individual patterns of habitat use emerge from behavioral decisions driven by interactions between landscape characteristics and individual traits. Individual traits, such as age and sex, influence the net gain of using ... -
Weather affects temporal niche partitioning between moose and livestock
Herfindal, Ivar; Lande, Unni Støbet; Solberg, Erling Johan; Rolandsen, Christer Moe; Roer, Ole; Wam, Hilde Karine (Journal article; Peer reviewed, 2017)Co-existing species at the same trophic level often segregate with respect to diet, habitat use, or spatial distribution, reducing their direct competition for resources. However, temporal patterns in species-specific ... -
Årsrapport fra NINAs Elgmerkingsprosjekt i grenseområdet Akershus, Hedmark og Østfold i 2004
Heim, Morten; Solberg, Erling Johan; Sæther, Bernt-Erik (NINA rapport;12, Research report, 2005)Prosjektet ser på hvilke faktorer som påvirker bestandssvingningene i norske elgbestander. I denne regionen er prosjektet spesielt fokusert på hvordan en stedlig ulvebestand påvirker re-krutteringen til elgbestanden. Denne ... -
