Data for "Plant identity and traits determine pollinator, natural enemy, herbivore and decomposer abundances in flower plantings"

Data collection 1

• Mode of collection: Field observation
• Description of the mode of collection: Vacuum sampling (30s in a 1m by 1m quadrat, once a week for three consecutive weeks, while the target plant species in the plot was in bloom) for leaf-dwelling arthropods.
• Time period(s) for data collection: 2020-07-01 – 2021-09-03
• Data collector: Swedish University of Agricultural Sciences
• Instrument: Modified leaf vacuum - Modified leaf vacuum
• Instrument: Quadrat - 1m by 1m quadrat located at the center of each plot used to define the area in which to do the vacuum sampling.
• Sample: Leaf dwelling arthropods
  Arthropods obtained by vacuum sampling stored in 70% ethanol.
• Source of the data: Other
• Temporal resolution: 7 day
• Spatial resolution: 543 kilometres

Data collection 2

• Mode of collection: Field observation
• Description of the mode of collection: Visual observations (60 s, twice a week, while the target plant species in the plot was in bloom) for pollinators.
• Time period(s) for data collection: 2020-07-01 – 2021-09-03
• Data collector: Swedish University of Agricultural Sciences
• Instrument: Pollinator net - Pollinator net used to collect the unkown pollinators observed during the visual observations
• Sample: Pollinators
  Captured individuals from pollinator observations. Pinned, identified and stored
• Source of the data: Other
• Temporal resolution: 7 day
• Spatial resolution: 543 kilometres

Data collection 3

• Mode of collection: Field observation
• Description of the mode of collection: Floral area and plant cover were estimated using a 1m by 1m quadrat located at the center of ach plot. For floral area, in each plot, the number of floral units was counted and then multiplied by the average floral area. A floral unit was equal to an individual flower in most species, but for Asteraceae and clovers (Trifolium spp.) we counted each inflorescence as a floral unit. Average floral area was estimated in each plot by measuring the diameter (actinomorphic or composite flowers) or length and width (zygomorphic flowers) of five floral units of the target plant species. Plant cover was estimated as the percentage plant cover of the sown plant species.
• Time period(s) for data collection: 2020-07-01 – 2021-09-03
• Data collector: Swedish University of Agricultural Sciences
• Instrument: Caliper - To estimate the floral area. We measured the diameter (actinomorphic or composite flowers) or length and width (zygomorphic flowers) of five floral units of the target plant species in each plot. Surveys were performed weekly within 2 days of sampling pollinators and leaf-dwelling arthropods while the target species was in bloom
• Instrument: Quadrat - 1m by 1m quadrat located at the center of each plot used to define the area in which to do the vacuum sampling.
• Source of the data: Other
• Temporal resolution: 7 day
• Spatial resolution: 543 kilometres

Data collection 4

• Mode of collection: Field observation
• Description of the mode of collection: Soil samples consisting on a composite sample made of three samples per plot (at 1.5m, 2.5m and 3.5m distance along a central transect along the length of the plot; 2cm diameter, 15cm depth).
• Time period(s) for data collection: 2020-09-21 – 2021-10-03
• Data collector: Swedish University of Agricultural Sciences
• Instrument: Soil corer - 2 cm diameter
• Sample: Nematodes
  Nematodes obtained with the soil corers, exctracted with modified Baermann funnels (Viketoft et al. 2005), heat-killed and fixated in formalin.
