Description
This dataset was produced as part of a research project investigating the influence of urbanization on the chemical diversity of Thyme populations and on the associated pollinator communities.
The dataset includes only pollinator data: occurrences and abundances of flower-visiting insects recorded on 11 Thyme populations located within the municipality of Montpellier (France).
Temperature measurements and analyses of Thyme chemical variability were conducted during the study, but these data are not included in the present dataset.

Sampling Methods
Pollinator communities were surveyed through standardized visual observations conducted on flowering Thymus vulgaris populations. At each site, observers recorded all flower-visiting insects and estimated their abundance during sampling sessions. Surveys focused on key pollinator groups, including bees, hoverflies, beetles, and other floral visitors. The protocol allowed the characterization of species occurrences, relative abundances, and community composition associated with each Thyme population. Environmental and plant chemical data were collected as part of the broader research project but are not included in this published dataset.
| Study Extent | The study was conducted in the municipality of Montpellier, southern France, within a Mediterranean urban landscape characterized by a mosaic of built areas, urban green spaces, and sclerophyllous habitats such as garrigue and shrublands. Sampling sites correspond to 11 populations of Thymus vulgaris distributed along an urbanization gradient, ranging from highly urbanized environments (parks, road verges, residential green areas) to more natural peri-urban habitats. This spatial design aimed to capture variability in environmental conditions and plant chemical diversity across contrasting urban contexts. |

Method step description:
- Field data were collected through direct visual surveys of insect visitors on flowering Thyme patches. Observers identified pollinators to the lowest possible taxonomic level and recorded abundance values for each taxon. Following field collection, data were digitized, standardized, and formatted for integration into biodiversity information systems. Taxonomic names were harmonized using the TAXREF reference taxonomy. Geographic coordinates and sampling dates were validated and formatted according to Darwin Core standards. Quality control procedures were applied to ensure data consistency prior to publication.
