Complex relationship between soil fungi and conservation value assessments in boreal forests Open
Large‐scale industrial forestry is a threat to biodiversity and imposes long‐lasting changes to many forested biomes. Preserving forests as reserves is an important component of the strategy for safeguarding forest biodiversity. Yet, the s…

Large-scale wall-to-wall mapping of bark beetle damage and forest practices using the distance red swir index and operational harvester data Open
Satellite-based inventories of bark beetle attacks are increasingly used for detecting and monitoring infested forest at the landscape scale. The Normalized Distance Red & SWIR index is one of few indices that have shown higher accuracies …

Climate change-induced shifts in survival and size of the worlds’ northernmost oviparous snake: A 68-year study Open
Because of their dependence on ambient temperature ectothermic animals can serve as sentinels of conservation problems related to global warming. Reptiles in temperate areas are especially well suited to study such effects, as their annual…

Different triggers, different stories: Bark-beetle infestation patterns after storm and drought-induced outbreaks Open
In the recent decades, Norway spruce forests (Picea abies Karst.) in Europe have been subject to large-scale tree mortality caused by the spruce bark beetle (Ips typographus L.). The outbreaks were induced by storm-felling events and perio…

Habitat heterogeneity is a good predictor of boreal forest biodiversity Open
Reliable assessment measures are crucial for tracking changes in biodiversity and for evaluating the state of biodiversity. Two of the main drivers of biodiversity are habitat heterogeneity and resource amount. These drivers are used as pr…

Beetle diversity in dead wood is lower in non‐native than native tree species, especially those more distantly related to native species Open
Non‐native tree species are widely used in forest plantations. This may have negative consequences for biodiversity. Hitherto, most studies have compared species diversity between native and non‐native forest stands, which makes it difficu…

Multi-taxon conservation in northern forest hot-spots: the role of forest characteristics and spatial scales Open
Context Biodiversity is highly affected by industrial forestry, which leads to the loss and fragmentation of natural habitats. To date, most conservation studies have evaluated associations among a single species group, forest type, or spa…

Occurrence of Batrachochytrium dendrobatidis in Sweden: higher infection prevalence in southern species Open
The chytrid fungus Batrachochytrium dendrobatidis ( Bd ) has caused worldwide declines in amphibian populations. While Bd is widespread in southern and central Europe, its occurrence and distribution in northernmost Europe is mostly unknow…

Chytrid fungus dynamics and infections associated with movement distances in a red‐listed amphibian Open
Amphibians are among the most threatened vertebrate taxa due to anthropogenic habitat change and emerging pathogens. The fungus Batrachochytrium dendrobatidis ( Bd ) may cause trade‐offs between the immune responses and other important fun…

Urban environment and reservoir host species are associated with Batrachochytrium dendrobatidis infection prevalence in the common toad Open
Human-induced changes of the environment, including landscape alteration and habitat loss, may affect wildlife disease dynamics and have important ramifications for wildlife conservation. Amphibians are among the vertebrate taxa most threa…

Effects of host species and environmental factors on the prevalence of Batrachochytrium dendrobatidis in northern Europe Open
The fungal pathogen Batrachochytrium dendrobatidis (Bd) poses a major threat to amphibian populations. To assist efforts to address such threats, we examined differences in Bd host infection prevalence among amphibian species and its relat…

Effects of host species and environmental factors on the prevalence of <i>Batrachochytrium dendrobatidis</i> in northern Europe Open
The fungal pathogen Batrachochytrium dendrobatidis ( Bd ) is a major threat to amphibian populations. Here we asked if the prevalence of Bd differs between amphibian species and whether it is related to local environmental factors in breed…

Forest restoration as a double‐edged sword: the conflict between biodiversity conservation and pest control Open
Summary Forestry has markedly changed a large proportion of the world's boreal forests, often with negative effects on biodiversity. As a result, forest restoration is increasingly implemented to counteract the negative effects. However, r…
