Winter browsing by moose ( <i>Alces alces</i> ) in a forested mountainous landscape of west–central Sweden Open
Browsing ecology involving ungulates and their food resource is complex as consumption may reflect responses to various factors, such as quantity and quality of browse species. This study investigated winter browsing by moose Alces alces i…

Climate change and deer in boreal and temperate regions: From physiology to population dynamics and species distributions Open
Climate change causes far‐reaching disruption in nature, where tolerance thresholds already have been exceeded for some plants and animals. In the short term, deer may respond to climate through individual physiological and behavioral resp…

Forest roads in Sweden – infrastructure with multiple uses and diverse impacts Open
Since the 1950s, more than 200 000 km of roads have been built in Sweden’s forests, making them easily accessible and open to multiple uses. The aim of this study was to review the impacts of forest roads in Sweden from a broad perspective…

From simple metrics to cervid forage: Improving predictions of ericaceous shrub biomass Open
Common understory vegetation species such as the ericaceous shrubs bilberry (Vaccinium myrtillus), cowberry (V. vitis-idaea) and heather (Calluna vulgaris), are key forage plant species for moose and other large herbivores, as well as fulf…

Wildfire and prescribed burning impact moose forage availability and browsing levels in the northern boreal forest Open
Fire regimes and herbivore densities have in parts of the boreal been heavily impacted by human activities with consequences for vegetation, forage supply and ungulate use. In this study, we evaluate the effects of natural wildfires and pr…

View article: Browsing Damage on Scots Pine: Direct and Indirect Effects of Landscape Characteristics, Moose and Deer Populations
Browsing Damage on Scots Pine: Direct and Indirect Effects of Landscape Characteristics, Moose and Deer Populations Open
Reducing browsing damages from cervids (Cervidae) on economically valuable tree species is a challenging task in many countries. Apart from cervid abundance, landscape characteristics, such as forest composition, land use, forage availabil…
View article: Forage availability, supplementary feed and ungulate density: Associations with ungulate damage in pine production forests
Forage availability, supplementary feed and ungulate density: Associations with ungulate damage in pine production forests Open
Populations of large herbivores, including members of the deer family Cervidae, are expanding across and within many regions of the northern hemisphere. Because their browsing on trees can result in economic losses to forestry and strongly…

Data for ALS analysis of moose on forest structure across a network of exclosures in boreal forests Open
This dataset includes (1) metadata for a network of moose exclosures across the boreal biome (2) a metadata template that describes the variables in the metadata. (3) LIDAR metrics calculated for each open plot and exclosure. Note that the…

View article: Does recolonization of wolves affect moose browsing damage on young Scots pine?
Does recolonization of wolves affect moose browsing damage on young Scots pine? Open
Ungulates frequently cause damage to human livelihoods, such as agriculture, livestock or forestry. In Sweden, forestry is the dominating land use and is a very important source of income. Moose (Alces alces) browsing commonly causes damag…

Can trackers count free-ranging wildlife as effectively and efficiently as conventional aerial survey and distance sampling? Implications for citizen science in the Kalahari, Botswana Open
Estimating wildlife abundance is central to conservation. We compared two widely practiced standards for counting animals - aerial strip surveys and ground line transects - with interpreted counts of animal tracks. At equal sampling intens…

The complexity of interacting nutritional drivers behind food selection, a review of northern cervids Open
The research literature on food selection by large herbivores is extensive. Still, we are generally lacking in our knowledge of the influence of potentially interacting chemical contents of the food. We made a qualitative review of a syste…

The changing contribution of top‐down and bottom‐up limitation of mesopredators during 220 years of land use and climate change Open
Summary Apex predators may buffer bottom‐up driven ecosystem change, as top‐down suppression may dampen herbivore and mesopredator responses to increased resource availability. However, theory suggests that for this buffering capacity to b…
