地理涵蓋範圍

This dataset covers 32 sites of the Semois Valley National Park in Belgium (28,903 hectares). The wild bees have been collected in three main habitats: mesic grasslands (EUNIS E2), seasonally wet and wet grasslands (E3) and Tall-herb communities of humid meadows (E5.42). Some of these habitats have also been sampled: Valley mires, poor fens and transition mires (D2), riverine and fen scrubs (F9), dry grasslands (E1), Dry heaths (F4.2) and quarries.

分類群涵蓋範圍

All the individuals samples belong to the clade of Anthophila (i.e. wild bees).

取樣方法

To ensure data consistency, a standardised sampling protocol was followed. Each sampling session involved 40 minutes of effective net collection time, which refers to the time spent actively searching for individuals within the plot. When a bee was captured, the stopwatch was paused to place the individual in a vial and to record the relevant collection information as outlined below. The effective collection time resumed once the bee was secured in the vial. Bees were exclusively captured using nets. The captures were carried out along a variable transect, where the collector moved freely across the site, primarily guided by the presence of flowers or nesting sites, rather than following a linear transect, where the collector remained on a straight line across the site. The variable transect approach enhances the capture of bee diversity by allowing the collector to focus on key plants and areas with abundant flowering. Collected individuals were placed in vials containing ethyl acetate-soaked paper for euthanisation. During collection, data such as altitude, longitude, latitude, site reference, bee behaviour (whether in flight, on the ground, or on flowers), and, when applicable, the plant species visited were recorded. The sampling protocol also required specific weather conditions. Thus, all captures were conducted between 9 AM and 5 PM, with temperatures above 15°C, no wind or rain, and low cloud cover.

方法步驟描述:

1. All bees were identified to species level using identification keys under a binocular microscope, and each identification was subsequently validated by a taxonomist expert of the group. Specifically, Apidae identifications were confirmed by Frédéric Carion, Guillaume Ghisbain and Achik Dorchin, Megachilidae by Clément Tourbez, Halictidae by Thomas Brau and Simone Flaminio, Andrenidae by Thomas Wood, Colletidae by Romain Le Divelec, and Melittidae by Maxence Gérard.
