Landscape fragmentation constrains bumblebee nutritional ecology and foraging dynamics

The dataset regards DNA metabarcoding data of ITS2 marker of pollen carried by bumblebees. Data are obtained from different urban parks contrasting in terms of local features and surrounding urban matrix, we aimed to clarify how fragmentation and local flower availability shape bumblebee foraging dynamics by characterizing several components: the nutritional content and plant composition of collected pollen pellets, the trip length and the plant-nutrition association along a fragmentation gradient.
