Data from: Is nocturnal pollination important for crop production? Experimental evidence from small fruit crops

This dataset accompanies the following article: “Blareau E., Requier, F. (in revision) Is nocturnal pollination important for crop production? Experimental evidence from small fruit crops. Journal of applied entomology”. Using pollinator exclusion methods to prevent either diurnal or nocturnal pollinator visits to flowers of raspberry (Rubus idaeus), red currant (Ribes rubrum), and black currant (Ribes nigrum), we assess the contributions of day-active and night-active pollinators to yield of these crops, measured via fruit set, fruit mass, fruit volume and seed set. We find that nocturnal pollination improves seed set of all three crops, as well as fruit volume of red currant, compared to exclusion of all insect visits. This confirms the existence of nocturnal pollination services for these crops.
Two datasets are available:
(1) Fruit_set : This dataset contains information on the number of flowers that successfully produced fruits for the different pollination treatments and for the different crops:
Metadata:
80 obs. of 5 variables
Plant_sp: Factor variable. Species of plant, with RB: Raspberry ; BC: Black currant ; RC: Red currant
Treatment: Factor variable. Pollination treatment, with Closed: Flowers never exposed to pollinators ; Night: flowers exposed to pollinators only during the night-time ; Day: flowers exposed to pollinators only during the daytime ; Day+Night: Flowers always exposed to pollinators.
Fruit_set_success: Numeric variable. Number of flowers per inflorescence that successfully produced a fruit.
Fruit_set_failure: Numeric variable: Number of flowers per inflorescence that failed to produce a fruit.
Year: Factor variable. Experimental year.

(2) Fruit_quality: This dataset contains information on qualitative measurements of individual fruits.
Metatdata:
223 obs. of 8 variables
Plant_sp: Factor variable. Species of plant, with RB: Raspberry ; BC: Black currant ; RC: Red currant
Treatment: Factor variable. Pollination treatment, with Closed: Flowers never exposed to pollinators ; Night: flowers exposed to pollinators only during the night-time ; Day: flowers exposed to pollinators only during the daytime ; Day+Night: Flowers always exposed to pollinators.
Mass.g: Numeric variable. Fruit mass, in g.
Height.mm: Numeric variable. Fruit height, in mm.
Width.mm: Numeric variable. Maximum fruit width, in mm.
Fruit_vol.mm: Numeric variable. Fruit volume, calculated from height and width measurements, in mm3.
Seed_set: Numeric variable. Number of seeds.
