Global climate change threatens to substantially rearrange species interactions, yet we lack clear predictions on how these changes will cascade through communities. Many perturbations associated with climate change, such as droughts, will change resource levels, with consequences for species interactions and thus ecological network structure. Diet theory predicts foraging niche expansion when preferred...
Insects are particularly vulnerable to rapid environmental changes, which are disproportionally affecting high latitudes. Increased temperature could influence insect species differentially and reshape assemblages over time. We quantified temporal assemblage turnover of Arctic Diptera (flies) in the Muscidae, one of the most diverse and abundant families of Arctic insects, using time series data from...
Higher Diptera (Schizophora) are taxonomically and ecologically diverse, and include bog specialist and bog-associated species known to respond to peatland disturbance. We examined the effects of three factors (habitat size, vegetation cover and surrounding land use measured in concentric circles of 500, 1000, 1500, and 2000 m radii from the sampling location) on Schizophora species richness, diversity,...
