The Anglesey lakes, Wales, UK—A palaeolimnological study of the eutrophication and nature conservation status

A mid-20th century stratigraphical Anthropocene is recognisable in the birth-area of the industrial revolution

“…The increase in δ 15 N from the early 1800s CE to the late 1990s also supports the biological data, indicating an early phase of eutrophication driven by an increase in the use of fertiliser. Similar timescales of eutrophication, dating to the early to mid-19th century, have been reported for other lakes in the UK (Bennion et al, 2011; Haworth et al, 1996) and across Europe (Battarbee et al, 2011), particularly linked to agricultural intensification (O’Sullivan, 1992; Ulén et al, 2007). Hence, it could be argued that there is a regional stratigraphical signal, or indeed a global signal of eutrophication in lakes from approximately this time (Battarbee et al, 2011; Hampton et al, 2018; Jenny et al, 2020).…”

In vitro culture and conservation of microalgae: Applications for aquaculture, biotechnology and environmental research

“…Diatoms are particularly important, as the silicon components of these microalgae provide almost permanent markers of the changes that have occurred in diatom populations. By analyzing the remains of diatoms sampled from sedimentary cores of terrestrial and aquatic environments, it is possible to gain an understanding of the history associated with pollution events and climatic change (Haworth et al, 1996).…”

The past, present and future of Llangorse Lake—a shallow nutrient-rich lake in the Brecon Beacons National Park, Wales, UK

“…More recently, a number of studies have been developed which assess the current condition of lakes with respect to defined 'baseline states' (e.g. Bennion et al, 1996;Haworth et al, 1996;Moss et al, 1996a;Duigan et al, 1998).…”
