Mammals in the British Isles looks at the influences on their numbers and distribution, both now and in the past, examines aspects of their biology with emphasis on function and physiology, and concludes with an account of relationships with man.This book by Dr Harrison Matthews will be warmly welcomed by all those for whom his British Mammals, in this series, was a standard work for nearly 30 years. In recent years our understanding of the British species has expanded greatly. This volume offers a synthesis of modern knowledge derived from living animals studied in the field and covering all facets of mammalian life in the British Isles. It will be as important to a new generation of naturalists as the previous book was to an older one.The book is full of fascinating detail – of the shrews which scream in defence of territory to avoid fighting; of young rats that play to learn while adult otters play for fun; of vole 'plague' populations which crash as a result of stress; of monogamy and parental care of the dog fox – but it also paints a broader picture of interdependence, conservation and the part played by man.As much a part of nature as any other member of the fauna, it is man who has created the character of the environment – by clearing, draining, building and developing agriculture – and made available the wide variety of habitats occupied by indigenous, introduced and feral populations.Dr Harrison Matthews gives a general account of British mammals and the things influencing their numbers and distribution both now and in the past, examines aspects of their biology with emphasis on function and physiology, and concludes with an account of relationships with man and the measures he has taken for their control and conservation.

At about the end of the Devensian glaciation the upper palaeolithic culture that man had evolved through many grades during the middle Pleistocene, was succeeded by the mesolithic culture characterised by the small flint artifacts called ‘microliths’. Of the several known mesolithic occupational sites, that at Starr Carr near Scarborough in Yorkshire has been meticulously excavated by Professor J. Clark and his colleagues, who have been able to draw a picture of the life of the inhabitants, and of the fauna and flora. 35The site was occupied about 9,500 years ago as a winter hunting camp by three or four families of nomadic people; the settlement lay at the edge of a lake in the Vale of Pickering, with closed birch forest on the hill rising behind and willows along the reedy shore. The people lived on a platform of birch brushwood and were occupied not only in hunting and gathering roots of reeds and bog-bean, but also in knapping flint to make tools, some of which were used for making barbed spearheads from slivers cut from the antlers of red deer. The bones and antlers they left on the site show that they lived mostly on the flesh of red deer, but that they also killed roe deer, elk, aurochs and wild boar in lesser numbers. They had no domestic animals, and did not cultivate any crops. The remains of other mammals show that the fauna included the pine marten, fox, wolf, badger, hedgehog, hare and beaver.

This late Pre-boreal fauna shows that forest animals, the deer and aurochs, had replaced the tundra-living mammals such as the reindeer, bison and wild horse while the birch forest increased with the rise in temperature. Until the rise in sea level at the end of the Preboreal phase, although Ireland had long been separated from Great Britain, the site of the southern part of the North Sea was dry land with the coast line extending from Flamborough Head to Jutland with a northern loop including the Dogger Bank. At the same time the English Channel extended no further east than Beachy Head.

The mesolithic people remained in occupation for over five thousand years, during which the sea level rose and cut off the British Isles from the continent. About 4,500 years ago the neolithic people arrived, migrating across the sea from the east, and soon completely replaced the mesolithic culture with their own. Throughout the many hundreds of thousands of years of the preceding part of the Pleistocene the palaeolithic and later the mesolithic people were no more than part of the fauna, and produced no appreciable alteration in the environment. They were plant gatherers and hunters and, though they may have contributed towards the extinction of some of the large mammals such as the mammoth, their influence on the composition of the fauna was in general negligible. They probably had to work hard to earn their living in the British Isles, but further south on the continent, where the climate was milder and food abundant, they appear to have satisfied their wants more easily so that they had enough leisure to make paintings on the walls of caves, to make sculptures and carvings, and to engrave stones and bone artifacts with abstract and representational designs.
