| Summary: | In a warming world, changes in climate may result in species-level responses as well as changes in community structure through knock-on effects on ecological interactions such as predation and herbivory. Yet, the links between these responses at different levels are still inadequately understood. Assessing how microclimatic conditions affect each of them at local scales provides information essential for understanding the consequences of macroclimatic changes projected in the future. Focusing on the rapidly changing High Arctic, we examine how a community based on a common resource species (avens, Dryas spp.), a specialist insect herbivore (Sympistis zetterstedtii), and natural enemies of lepidopteran herbivores (parasitoids) varies along a multidimensional microclimatic gradient. We ask (1) how parasitoid community composition varies with local abiotic conditions, (2) how the community-level response of parasitoids is linked to species-specific traits (koino- or idiobiont life cycle strategy and phenology) ... : This dataset comprises of parasitoids caught during summers 2015 and 2015 at 20 sampling sites distributed at different elevations and snowmelt charasteristics near the Zackenberg research stations in North-East Greenland. All sites were of Dryas heath habitat, characterised by Dryas octopetalaXintegrifolia dominated vegetation. Trapping of parasitoids was done using 10 open sticky traps (5cm by 4.5cm white sticky traps cut out from sticky board: Barrettine Environmental, UK [product no longer available]) and 5 emergence traps (with a half a square metre footprint) placed on Dryas tussocks. The traps were emptied every six days 4 sites a time in a rolling schedule. The parasitoids were subsequently picked of off the sticky traps, their whole DNA was extracted and half of their Cytochrome Oxidase I barcode region was amplified using Primers B-F and HCO. See the supplementary information of the publication for more details. The dual tag indexed library of parasitoid samples was sequenced at the FIMM Technology ... |
