Insect Herbivory Releases More Nutrients in Warmer and Drier Forests Open
Climate, forest successional stage, and soil substrate age can alter herbivore communities and their effects on biogeochemical cycling, but the size and spatial variability of these effects are poorly quantified. To address this knowledge …

Predation on Live and Artificial Insect Prey Shows Different Global Latitudinal Patterns Open
Aim Long‐standing theory predicts that the intensity of biotic interactions increases from high to low latitudes. Studies addressing geographic variation in predation on insect prey have often relied on prey models, which lack many charact…

The impact of insect herbivory on biogeochemical cycling in broadleaved forests varies with temperature Open
Herbivorous insects alter biogeochemical cycling within forests, but the magnitude of these impacts, their global variation, and drivers of this variation remain poorly understood. To address this knowledge gap and help improve biogeochemi…

Change in the life history trait? – an alternative overwintering strategy of the Macaria fusca (Thunberg, 1792) (Lepidoptera, Geometridae, Ennominae) Open
Macaria fusca (Thunberg, 1792) is a small geometer moth species that inhabits mountain heathland just above the timberline and occasionally warm forest openings in the mountains. Existing literature describes the species overwintering as a…

Large‐scale long‐term passive‐acoustic monitoring reveals spatio‐temporal activity patterns of boreal bats Open
The distribution ranges and spatio‐temporal patterns in the occurrence and activity of boreal bats are yet largely unknown due to their cryptic lifestyle and lack of suitable and efficient study methods. We approached the issue by establis…

A curated DNA barcode reference library for parasitoids of northern European cyclically outbreaking geometrid moths Open
Large areas of forests are annually damaged or destroyed by outbreaking insect pests. Understanding the factors that trigger and terminate such population eruptions has become crucially important, as plants, plant‐feeding insects, and thei…

Parasitoids indicate major climate‐induced shifts in arctic communities Open
Climatic impacts are especially pronounced in the Arctic, which as a region is warming twice as fast as the rest of the globe. Here, we investigate how mean climatic conditions and rates of climatic change impact parasitoid insect communit…

Phytochemical Shift from Condensed Tannins to Flavonoids in Transgenic Betula pendula Decreases Consumption and Growth but Improves Growth Efficiency of Epirrita autumnata Larvae Open
Despite active research, antiherbivore activity of specific plant phenolics remains largely unresolved. We constructed silver birch ( Betula pendula ) lines with modified phenolic metabolism to study the effects of foliar flavonoids and co…

Hiding in the background: community-level patterns in invertebrate herbivory across the tundra biome Open
Invertebrate herbivores depend on external temperature for growth and metabolism. Continued warming in tundra ecosystems is proposed to result in increased invertebrate herbivory. However, empirical data about how current levels of inverte…

Flower‐visitor communities of an arcto‐alpine plant—Global patterns in species richness, phylogenetic diversity and ecological functioning Open
Pollination is an ecosystem function of global importance. Yet, who visits the flower of specific plants, how the composition of these visitors varies in space and time and how such variation translates into pollination services are hard t…
