Relationships among recent Alpine Cladocera remains and their environment: implications for climate-change studies [PDF]

open access: yes, 2018
Our objective was to assess the potential of Cladocera from mountain lakes for climate reconstruction. We related Cladocera from surface sediments of Alpine lakes (1,502-2,309masl) to 29 abiotic environmental variables using statistical methods.
