Solitary Bees and Bumblebees in a Danish Agricultural Landscape - data from PhD-study

Latest version published by Natural History Museum of Denmark on Aug 29, 2017 Natural History Museum of Denmark

This dataset contains the recordings of bees from the PhD-study by Isabel Calabuig on: "Solitary Bees and Bumblebees in a Danish agricultural landscape 1997-2000". In a survey April through November 1997, a total of 72 solitary bee species and 19 bumblebee species were recorded in the semi-natural habitats of a conventional agricultural landscape. The study contains a total of 1091 sampling events from a total of 64 window traps in yellow pan-traps, yielding a total of 13.700 individual bee specimens.

Data Records

The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 1,092 records. 1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

Project Data

The PhD-study constituted a part of the project: "Novel strategies in weed control providing for environment, economy, and landscape resources". The project was a cooperation between four departments of former institutes "Danish Institute of Agricultural Sciences (D.I.A.S)" and "Danish Forest and Landscape Research Institute", and the University of Copenhagen. The project as a whole was part of the research programme: "Land use - farmers as landscape managers (1997-2001)". Supervisor on the PhD-study was Associate Professor Mikael Münster-Swendsen (deceased). The study was carried out at the then Department of Population Ecology, University of Copenhagen, January 1997 through June 2000. The aim of the PhD-study was to clarify several aspects of the ecology and biology of solitary bees and bumblebees occurring in the fragmented semi-natural habitats of a Danish agricultural landscape: · Seasonal activity and succession of bee species · Species richness and relative abundance · Estimation of the actual number of species occurring in the agricultural landscape · Foraging- and nesting conditions in hedgerows, dry-stone walls, forest edges, fieldborders and other linear and areal habitats · Maintenance and founding of bee habitats for foraging and nesting

Title Solitary Bees and Bumblebees in a Danish Agricultural Landscape
Funding Project financed by the then called Ministry of Environment & Energy and the Ministry of Food, Agriculture & Fisheries.
Study Area Description Study area in mid-Zealand (Denmark) was chosen based on having suitable areas of arable land that contained a reasonable continuum of different semi-natural habitats.
Design Description Window-traps/flight interceptors in yellow pan-traps filled with water and detergent to reduce surface tension. Placed 100 meters apart along different kinds of seminatural habitats (forest edge, hedgerow etc.) in the overall agricultural landscape. Emptied roughly once a week. All traps and transects were mapped with a GPS. Link to Google map with traps indicated: https://drive.google.com/open?id=1BcoGsRV1GlBlQAM_K58CjLvPkvA&usp=sharing.

Sampling Methods

Traps were normally emptied once a week. Trap yields were rinsed and stored in 70% ethanol.

Study Extent In the agricultural landscape, three transects were selected, each two kilometres long, along varying types of semi-natural habitats. Small window-traps standing in yellow pan-traps with liquid was used to attract and trap the bees. The traps were placed along the habitats with a constant distance of 100 metres, coming to a total of 64 traps.
Quality Control The material was sorted and all bee specimens counted and identified to species. Colourimetric properties of the yellow pan-traps were measured, and the traps' efficiency of attracting bees was evaluated. Representatives of all species recorded are kept as dry pinned specimens at Natural History Museum of Denmark, currently in personal collection of Isabel Calabuig at the museum.
