Floral visitors and pollinators of Silene migjornensis

This dataset contains data on the floral visitor surveys conducted on Silene migjornensis in the population of Sa Ràpita (Mallorca, western Mediterranean Basin) during the flowering season of 2024 as well as data on the taxonomic identification and pollen load of collected specimens (number of pollen grains of S. migjornensis and other pollen grains loaded)., Direct captures of floral visitors observed on S. migjornensis flowers and indirect captures using a light tramp for nocturnal pollinators (Robinson Mercury Moth Trap) were conducted in the natural population in Platja de sa Ràpita (29º 21’N 2º 57’S), once or twice a week during April 2024. Floral visitor surveys were conducted at 2-hour intervals from 18:00 to 4:00 solar time in four non-consecutive days along the flowering period. In each survey, the number of floral visitors on five groups of 100 flowers were recorded. Captured floral visitors were frozen for taxonomic identification and pollen load analyses.
Reagarding pollen load analyses, pollen was extracted from the body surface using cubes of fuchsine glycerogelatin. The gel cube was rubbed to the body surface, heated to melt, and mounted on a slide for pollen counting and identification under a stereomicroscope. To standardise the pollen counts, four fields of view were counted using a 4x magnification objective. Pollen identi..., , # Floral visitors and pollinators of *Silene migjornensis*

本数据集包含2024年开花季期间，在西地中海盆地马略卡岛萨拉皮塔（Sa Ràpita）种群的*Silene migjornensis*（麦瓶草）上开展的花访客（floral visitor）调查数据，以及采集标本的分类鉴定与花粉负载（pollen load）数据（含麦瓶草花粉粒及其他花粉粒的负载数量）。

研究在普拉亚德萨拉皮塔（Platja de sa Ràpita，坐标29°21′N，2°57′S）的自然种群中，分别通过直接捕捉法采集麦瓶草花上的访客，以及利用罗宾逊汞蛾诱捕器（Robinson Mercury Moth Trap）夜间捕捉传粉者（pollinator），采样频率为每周1-2次，时间跨度为2024年4月。

花访客调查在开花期内选取4个非连续日期，以太阳时18:00至次日4:00为时段，每2小时开展1次。每次调查中，记录5组各100朵花上的花访客数量。捕获的花访客经冷冻保存，用于后续分类鉴定与花粉负载分析。

关于花粉负载分析：研究人员使用品红甘油明胶（fuchsine glycerogelatin）方块从标本体表提取花粉——将凝胶方块擦拭标本体表后加热融化，封片后置于体视显微镜（stereomicroscope）下进行花粉计数与种类鉴定。为统一花粉计数标准，采用4倍物镜对4个视野进行计数。花粉鉴定……
