  • This dataset contains in situ CO2 efflux, root production and fungal hyphae production from plots distributed across a subarctic landscape in Northern Sweden. 6 paired plots were established in mountain birch forest and 5 paired plots were established in tall shrub tundra where one of each pair was 'girdled' and one acted as a non girdled 'control'. Efflux measurements were made during six sampling campaigns over 2017 and 2018 at an approximate frequency of once per week during each campaign, constituting a time series of measurements. Production measurements integrated root or hyphae production over the whole growing season (June-September) and therefore there is one datapoint per plot per year.

  • This dataset constains information on population counts in experimental populations of Plodia interpunctella (Pyralidae; Hübner) and the parasitoid wasp Venturia canescens (Ichneumonidae; Gravenhorst). The data was collected from a multi-generation microcosm experiment carried out to characterise the combined effects of daily stochastic temperature fluctuations and resource degradation on population responses in the Plodia-Venturia host-parasitoid trophic interaction. The population count data include the weekly total numbers of dead adult hosts and parasitoids and the numbers of live early (L1-L3) and late (L4-L5) host instars and of host and parasitoid pupae in half sections of diet removed weekly and replaced by fresh diet (half sections are a 12th of experimental population boxes). The temperature time series data include the date and daily temperature in the fluctuating temperatures treatment.

  • This dataset contains information on life history traits of the host Plodia interpunctella (Pyralidae; Hübner) and the parasitoid wasp Venturia canescens (Ichneumonidae; Gravenhorst). The data was collected from a single generation life history experiment investigating the combined effects of daily stochastic temperature fluctuations and resource degradation on individual life history in the Plodia-Venturia host-parasitoid trophic interaction. The Plodia interpunctella data include egg viability, egg status, hatching date, adult emergence date, date of death, sex, egg length in mm, and adult leg (mid-femur) length in mm. The Venturia canescens data include adult emergence date, adult emergence outcome (i.e., the species that emerged from parasitized host larvae), date of death and adult leg (hind-tibia) length in mm. The temperature time series data include the date and daily temperature in the fluctuating temperatures treatment.

  • [This nonGeographicDataset is embargoed until July 17, 2021]. This dataset contains information on life history variation and population dynamics in response to coloured environmental variation in the laboratory model system comprised of the moth Plodia interpunctella (Pyralidae; Hübner) and the parasitoid wasp Venturia canescens (Ichneumonidae; Gravenhorst). Data were collected from two complementary experiments investigating the effects of daily coloured temperature fluctuations on individual life history variation (single-generation life history experiment) and population dynamics (multi-generation microcosm experiment) in both species. In both experiments, the effects of three types of coloured noise were investigated and compared to constant temperature conditions: blue noise (characterized by rapid (negatively autocorrelated) fluctuations), red noise (characterized by slow (positively autocorrelated) fluctuations) and white noise (characterized by random fluctuations). The life history experiment lasted 56 days and the microcosm experiment lasted 310 days.
