She has done an outstanding job classifying near 1k specimens into 165 bee species from urban parks and semi-natural areas in Viladecans (a small town near Barcelona). That means about 15% of the total bee species richness described for the whole Iberian Peninsula!
Besides, she has analysed if urban parks are merely a subset of the assemblages of the surrounding natural areas. Spoiler: they are not! Nestednees contribution to beta diversity is minor compared to the pure turnover component.
