Adaptive Strategies and Population Ecology of Northern Grouse was first published in 1988. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions. This book is at once a major reference to the species of grouse that inhabit North America and the Holarctic and a synthesis of all the available data on their ecology, sociobiology, population dynamics, and management. The book undertakes to answer two long-standing questions in population ecology: what actually regulates the numbers within a population, and what are the breeding and survival strategies evolved in this northern environment? For Volume I, editors Arthur T. Bergerud and Michael W. Gratson have drawn together their own work and that of colleagues in North America, Iceland, and Norway—in all, eleven research studies, averaging six years' duration, on eight species of grouse. These studies deal with the blue and ruffed grouse of the forest habitat; the sharp-tailed grouse, prairie chicken, and sage grouse of the prairie or steppe; and the white-tailed, rick, and willow ptarmigan found in alpine and arctic tundras. The authors describe the rich repertoire of behavior patterns developed by the hen and the cock to achieve their two primary objectives—first, to stay alive, and then to breed. Volume II, primarily the work of Bergerud, synthesizes the evidence in Volume I and in the grouse research literature from a theoretical perspective. Several potentially controversial sociobiological hypotheses are advanced to account for flocking behavior, migration, dispersal, roosting and feeding behavior, mate choice and mating systems. The demographic analysis provides new insights into cycles of abundance, the limitation of numbers, and the demographic factors that determine densities. The contributors, besides Bergerud and Gratson: R.C. Davies, A. Gardarson, J.E. Hartzler, R.A. Huempfner, D.A. Jenni, D.H. Mossop, S. Myrberget, R.E. Page, R.K. Schmidt, W.D. Svedarsky, and J.R. Tester.
Migrations and population dynamics are considered very problematic topics in the fields of ancient studies. Recent scholarship in (pre)historical population has generated new impulses by using scientific approaches using radiogenic and stable isotopes, and palaeogenetics, as well as computer simulation. As a result, the state of migration research has undergone rapid change. Several research groups presented papers at aconference held in Berlin in 2010, addressing specific historical aspects of population dynamics and migration, with no chronological or geographical restrictions, in the light of cutting-edge bio-archaeological research. This volume, divided into three larger thematic sections (isotope analysis, population genetics, and modelling and computer simulation), presents experiences and insights about methodological approaches, research results and prospects for future research in this area in a varied collection of papers. Scholars from widely diverse scientific disciplines present their approaches, findings and interpretations to an audience far broader than the circles of the individual disciplines.
