1. Paleolimnological reconstructions of fish population changes in acidified lakes
Sammanfattning : This thesis deals with the potential of using subfossil Chaoborus spp. and Daphnia spp. remains preserved in lake sediments to reveal past fish community alterations related to progressive acidification. LÄS MER
2. Fingerprints of planktivory : paleolimnological evidence of past fish community structure and dynamics
Sammanfattning : Planktivorous fish affect the species composition, size and morphology of their zooplankton prey by size selective predation. Remains of cladocerans are deposited in the lake sediments and this microfossil community hence reflects the historical changes in the planktivore fish community. LÄS MER
