A new paper, included in Duarte Viana's PhD Thesis, is now in early view:
Viana, D., Santamaría, L., Schwenk, K., Manca, M., Hobaek, A., Mjelde, M., Preston, C.D., Gornall, R.J., Croft, J., King, R., Green, A.J., Figuerola, J.(2014) Environment and biogeography drive aquatic plant and cladoceran species richness across Europe. Freshwater Biology.
The paper builds on a survey carried out during EU-project LAKES to show that environmental filters and biogeography, but not dispersal, are the two major drivers of species richness in two major inland-water taxa (waterfleas and aquatic plants) across Europe.
