ABSTRACTIn this paper, the characteristics of the community of large mammals in the Province of Burgos (Old Castile, Spain) are evaluated by means of a method of census based on the battues carried out by two parties of hunters specializing in big game. The exhaustive character of the battues guarantees reliable results (Table 1). The historic evolution of these populations is also studied (Fig. 1).On the other hand, considering predator‐prey relations, the community in question is clearly favourable to the survival of the wol

摘要:

ABSTRACTGame bag records are used to examine temporal and geographical changes in numbers of Brown hares. Records are taken from a survey made by the Oxford Bureau of Animal Population in 1938, which covered over 400 estates, and from the Game Conservancy's National Game Census, which has been monitoring shooting records of between 400 and 500 estates since 1961. Eastern regions of Britain had higher bags of hares than western regions in the three periods; 1891–1910, 1917–1936, 1961–1978. Hare game bags were generally high in counties with large proportions of tilled land. There was no consistent temporal trend in bags from different areas before 1938, but all areas show a considerable reduction in bags since 1961. This reduction is statistically significant. Time‐series analysis of one extended set of data did not show evidence of cyclic fluct

ABSTRACTThe discovery of the Bank voleClethrionomys glareolusin Ireland and the published information on its spread are reviewed, and the results of a complete resurvey of its distribution, in 1982, presented. The rate of spread is extremely variable and somewhat unpredictable. Over suitable habitat—agricultural land with hedges and other cover (and sometimes mountain valleys)—spread may average 2–4.5 kmyr‐1but can sometimes be very much slower. This might be influenced by the type and extent of hedges and of permanent pasture. High ground and moorland usually prevent spread but there have been dramatic exceptions. In 1982 Bank voles occupied probably the whole of Co. Limerick; most of Co. Kerry, with the exception of substantial parts of the mountainous peninsulas in the southwest and contiguous interior; a large part of Co. Cork, though not the south‐east and again excepting portions of the mountainous south‐west, together with a substantial strip of east Co. Tipperary, and the south‐east quarter

摘要:

ABSTRACTFor any frustrated field‐mammalogists seeking observational data on their elusive study animals, dung may represent the most readily‐available and easily‐collected source of information upon which they may fall back in despair. Yet it is surprising how much ecological information may be deduced from an analysis of faecal depositions. This present article reviews some of the current methods available to the mammalogist for ecological detection from dung and some of the ecological areas in which it may offer inform
