Title

The seed set of Eschscholzia californica plants introduced into habitats comprising different floral cover

Abstract

This dataset contains seed counts of Eschscholzia californica plants introduced to form experimental arrays within habitats comprising different floral cover. Data was collected in June 2015 at the Hillesden estate, Buckinghamshire, UK. Experimental arrays comprised of three E.californica plants separated by 1m and arranged in a triangular formation. A total of sixteen arrays were introduced across four 100 hectare replicate blocks, each separated by >500m. At the centre of each block, four experimental arrays were placed at 50m intervals along a 150m transect laid symmetrically across the boundary between an established wildflower patch and bare, fallow ground or grazed grassland (two arrays within the florally rich habitat and two arrays within the florally poor habitat). On each plant, the seed set was measured for flowers which were exposed and excluded from pollinators to determine the effects of habitat context on plant reproduction. The dataset was part of a larger experiment looking at the effect of floral resources on the pollination services to isolated plants.

Lineage

The same experimental protocol was followed for all Eschscholzia californica plants. All open flowers were removed from the plants prior to their placement in pre-marked locations across the landscape. One bud on each plant was covered in a fine muslin to represent a 'pollinator excluded' flower. Plants remained in the field for 16 days to ensure full anthesis of new flowers and to allow for multiple pollination events. After this period, all fruit were tagged to ensure that only fruit development arising from the period of the field experiment were included in analyses. Plants were then collected and stored under controlled glasshouse conditions until fruit maturation. Upon maturation, tagged fruit were collected and the number of filled seeds per fruit were counted to quantify seed set per fruit. Data are provided as collected.
