Arctic ecosystems have long been thought to be minimal sources of volatile organic
compounds (VOCs) to the atmosphere because of their low plant biomass and cold …

Arctic terrestrial herbivores influence tundra carbon and nutrient dynamics through their
consumption of resources, waste production, and habitat‐modifying behaviors. The strength …

Plant damage by invertebrate herbivores and pathogens influences the dynamics of
grassland ecosystems, but anthropogenic changes in nitrogen and phosphorus availability …

Species interactions are known to structure ecological communities. Still, the influence of
climate change on biodiversity has primarily been evaluated by correlating individual …

Highlights•The Arctic is ideally suited for studying arthropod responses to climate
change.•Arctic arthropods are responding rapidly and in diverse ways to climate …

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 …

Aim Attempts over the past 30 years to explain geographical variation in the strength of
herbivore pressure have given rise to ecological hypotheses like the latitudinal herbivory …

The latitudinal herbivory hypothesis (LHH) predicts that plant losses to herbivores decrease
from low to high latitudes. Although the LHH is a community‐level hypothesis, it has been …

The latitudinal biotic interaction hypothesis (LBIH) predicts that the strength of various biotic
interactions decreases from low to high latitudes. Inconsistency between studies testing this …

Lichens play important roles in habitat formation and community succession in polar and
alpine ecosystems. Despite their significance, the ecological effects of lichen traits remain …
