► Limpet size reductions over the last 8200 years show no correlation to environmental changes; human population growth and increasing predation pressure appear to be primarily responsible.► Native Americans impacted Channel Island shellfish stocks over millennia; for fisheries manager's archaeological data can help solve the “shifting baselines” problem.

Following the partition of Ireland and the independence of the Irish Free State in 1922, which left Northern Ireland as the only part of the island of Ireland within the United Kingdom, the name "United Kingdom of Great Britain and Northern Ireland" was adopted.
Although the United Kingdom, as a sovereign state, is a country, England, Scotland, Wales and, to a lesser degree, Northern Ireland, are also regarded as countries, though they are not sovereign states.
With an area of 242,500 square kilometres (93,600 sq mi), the UK is the 78th-largest sovereign state in the world.
It is also the 21st-most populous country, with an estimated 65.5 million inhabitants in 2016.
Fluctuations in limpet size show no clear correlation with changes in sea surface temperature and marine productivity, suggesting that increased predation by growing human populations was primarily responsible for the reduction in size over time.
Our results provide further evidence that prehistoric peoples significantly influenced nearshore fisheries long before the development of the commercial and industrialized fisheries of historic times.► Size changes in the owl limpet (Lottia gigantea) through 10,000 years are examined.Five-sixths of Ireland seceded from the UK in 1922, leaving the present formulation of the United Kingdom of Great Britain and Northern Ireland.the remnants of the British Empire which, at its height in the 1920s, encompassed almost a quarter of the world's land mass and was the largest empire in history.It has a high-income economy and has a "very high" Human Development Index, ranking 16th in the world.It was the first industrialised country and the world's foremost power during the 19th and early 20th centuries.The UK is also a member of the Commonwealth of Nations, the Council of Europe, the G7 finance ministers, the G7 forum, the G20, NATO, the Organisation for Economic Co-operation and Development (OECD), and the World Trade Organization (WTO).
