Temporal rarity is a better predictor of local extinction risk than spatial rarity Open
Spatial rarity is often used to predict extinction risk, but rarity can also occur temporally. Perhaps more relevant in the context of global change is whether a species is core to a community (persistent) or transient (intermittently pres…

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…

Late‐season snowfall is associated with decreased offspring survival in two migratory arctic‐breeding songbird species Open
While the effect of weather on reproduction has been studied for many years in avian taxa, the rapid pace of climate change in arctic regions has added urgency to this question by changing the weather conditions species experience during b…

ARTHROPOD FOOD WEBS IN ARCTIC TUNDRA: TROPHIC INTERACTIONS AND RESPONSES TO GLOBAL CHANGE Open
Arctic ecosystems are undergoing rapid change. Terrestrial arctic arthropods (insects, spiders and others) are not only appreciably diverse, but also sensitive to their environment. As such, tundra arthropod communities and food webs could…

Nestling growth rates in relation to food abundance and weather in the Arctic Open
Raising nestlings to fledging is energetically demanding for songbirds, requiring parents to balance several major tradeoffs. Nestling growth rates are highly susceptible to variation in environmental conditions and parental investment, an…
