Book excerpt: Nils-Axel Marner &Wibjarn Karlen Organizers of the Stockholm Symposium in 1983 Stockholm University, Sweden This book is the Proceedings of the SECOND NORDIC SYMPOSIUM ON CLIMATIC CHANGES AND RELATED PROBLEMS held in Stockholm, Sweden, May 16-20, 1983 (Frydendahl et al., 1983; Marner, 1983). This was "an international interdisciplinary symposium with special refe rence to Nordic records and their relation to global climatic changes". The first NORDIC SYMPOSIUM ON CLIMATIC CHANGES AND RELATED PROBLEMS was held in Copenhagen in 1978 ( Frydendahl, 1978) and had a very broad scientific program. The SECOND NORDIC SYMPOSIUM was specifically directed to certain problems, time ranges and sources of information, as discussed below. Scandinavia is a classical area for the study of climatic fluctuations during the last 20,000 years . A major part of the basic data for the international theories and synthesis originate from Scandinavian data. This applies, for example, to: (1) The drastic climatic fluctuations in connection with the re cession of the land-ice giving rise to the alternation of inter stadials (warm periods with rapid ice recession) and stadials (cold periods with readvances or retardations in the ice recession). (2) The climatic changes during the Holocene with its well-known sub-division according to the Blytt-Sernander system (nowadays being used far outside the boreal region for which it was origi nally defined). (3) The Holocene climatic optimum and the subsequent climatic de terioration at around 2500 BP (well-established already at the beginning of this century).

Available in PDF, EPUB and Kindle. Book excerpt: "Through analysis of mitochondrial DNA (mtDNA) sequences, I examined phylogeographic relationships among moose (Alces alces) from Europe, Asia, and North America and inferred historic population trends explaining present-day structure of genetic variance. Diversity of mucleotide composition in cytochrome 'b' was low worldwide, with no variation detected among North American moose. The North American lineage was more closely related to European than to Asian lineages, indicating a recent colonization of North America and refuting the theory of eastern and western races of moose. An analysis of the control region provided greater resolution, which revealed similar yet more detailed patterns, including detectable variation within North America subspecies. Patterns of genetic variation among regional populations identified central Asia as the source of extant lineages of moose. Moreover, a recent coalescence was indicated, with the most recent common ancestor dating to the last ice age. Two historic expansions of moose populations were detected: an initial exansion in Eurasia coincident with an interstade of the last ice age, and a second expansion in eastern Asia and North America following the end of the last ice age. Data indicate a low effective population size in Eurasia during the peak of the last ice age followed by population and range exansion, likely facilitated by climate change. Haplotypes within North America formed a star phylogeny, indicative of recent expansion. Nucleotide and haplotype diversity were greatest in central North America and least in peripheral populations (Alaska, Colorado, and eastern North America). My data indicate a pattern of colonization consistent with a large central population providing founders for peripheral populations, perhaps resulting from leptokurtic dispersal. Low diversity in Alaska indicated a bottleneck susequent to colonization and recent population expansion. Establishment of regional populations through small numbers of founders combined with selection pressure for smaller body size likely led to morphological differentiation among regional populations and likely was adequate for rapid development of subspecies. Nucleotide and haplotype diversity were low in southeastern Alaska, but were high in neighboring areas of British Columbia; there little sharing of haplotypes occurred despite close proximity, indicating recent admixture of separate colonizing populations"l--Leaves iii-iv.

Download or read book Conservation of Exploited Species written by John D. Reynolds and published by Cambridge University Press. This book was released on 2001-10-18 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of wildlife for food and other human needs poses one of the greatest threats to the conservation of biodiversity. Wildlife exploitation is also critically important to many people from a variety of cultures for subsistence and commerce. This book brings together international experts to examine interactions between the biology of wildlife and the divergent goals of people involved in hunting, fishing, gathering and culling wildlife. Reviews of theory show how sustainable exploitation is tied to the study of population dynamics, with direct links to reproductive rates, life histories, behaviour and ecology. As such theory is rarely put into practice to achieve sustainable use and effective conservation, Conservation of Exploited Species explores the many reasons for this failure and considers remedies to tackle them, including scientific issues such as how to incorporate uncertainty into estimations, as well as social and political problems that stem from conflicting goals in exploitation.
