The Evolution of Pollution Evidenced by Lake Sediment Pseudofossils

Eutrophication of Freshwaters

“…Suitable remains are the siliceous frustules (shells) of diatoms and certain other algal groups (Livingstone, 1984), 'pseudofossils' of invertebrate animals such as cladocera (carapace remains) and chironomids (head capsule remains) (Deevey, 1942;Murray, 1979) (Fig. 1.10) and fish scales.…”

The use of Members of the Family Chydoridae (Anomopoda, Branchiopoda) as an Indicator of Lake Ecological Quality in Ireland

“…Pseudofossils of cladocerans, and chydorids in particular, have been widely used to reconstruct changing trophic or acid status (Frey 1960;Harmsworth and Whiteside 1968;Whiteside 1970;Boucherle and Züllig 1983;Hofmann 1987;Hann et al 1994;Jeppensen et al 1996;Brodersen et al 1998) and to infer changes in macrophyte and fish communities (Leavitt et al 1989;Stansfield et al 1989;Miskimmin et al 1995). Some Irish lakes have already been the focus of palaeolimnological studies in which cladocerans were used to recon-struct lake history (Murray 1979;Douglas and Murray 1987;Wood et al 1990Wood et al , 1996.…”
