Response of chironomids to Neolithic land-use change in north-west Ireland:

摘要: This study provides the first decadally resolved chironomid and organic geochemistry record of Irish Neolithic from a small lake adjacent to Carrowkeel-Keshcorran complex in County Sligo, Ireland. Chironomid (non-biting midge fly) sub-fossils sediment (δ13C, δ15N C:N) Templevanny Lough core were used assess timing magnitude within-lake responses farming activity. When compared with pollen macroscopic charcoal records same core, limnological data show direct influence prehistoric on freshwater system through nutrient loading eutrophication. Elevated levels, suggesting more productive system, subsequent turnover community indicate period intensive activity c. 3790–3620 BC early Neolithic. was followed by decline short periods small-scale human activity, exemplified loa...
