Методи обліку чисельності гризунів

Abstract

This is a republication of the methodological review originally published in 1957, which has been important for the organization of local and regional studies of the mammal fauna, particularly in the identification of species composition and estimates of the relative abundance of small (mouse-like) rodents. The present publication is accompanied by an editorial foreword and contains seven chapters. The first three are titled ‘Rodents as objects of census and monitoring,’ ‘Census of rodents and its components,’ and ‘Census of rodents in the field with attention to relative and absolute census.’ The section on relative census includes such topics as ‘Census by biological indicators,’ ‘Census by analysis of pellets and excrements of predators of mice,’ ‘Census by counting burrows (holes),’ and ‘Cenus on trap lines.’ The section on absolute census includes parts such as ‘Census by complete excavation of burrows and complete capture of their population’ and ‘Census of rodents in various kinds of haystack.’ The other sections are ‘Census of forest-dwelling rodents,’ ‘Census of rats and mice in human settlements’ (includes three parts: the method of dusty areas, the method of trial bait, and the method of almost complete capture), ‘Methods of combating certain species of harmful rodents’ (abridged), ‘Controlling methods of some species of harmful rodents’ (abridged), and ‘Collection and transfer to specialists of rodent materials for scientific purposes.’
