Pillars of Evolution provides a fresh and provocative perspective on adaptive evolution. Readers new to the study of evolution will find a refreshing new insight that establishes evolutionary biology as a rigorous and predictive science, whilst practicing biologists will discover a provocative book that challenges traditional approaches.The book begins by leading readers through the mechanics of heredity, reproduction, movement, survival, and development. With that framework in place, it then explores the numerous ways that traits emerge from the interactions between genetics, development, and the environment. The key message is that adaptive changes in traits (and their underlying allelic frequencies) evolve through the traits'' functions and their connection with fitness. The complex mappingsfrom genes-to-traits-to-fitness are characterized in the structure of evolution. A single "structure matrix" describes why individuals vary in the values of adaptive traits, their ability to perform the function of those traits, and in the fitness they accrue. Fitness depends on how organisms interact with and perceive theirenvironment in time and space. These relationships are made explicit in spatial, temporal, and organizational scale that also sets the stage for the crucially important role that ecology always plays in evolution. The ecological hallmarks of density- and frequency-dependent interactions allow the authors to explore new and exciting insights into evolution''s dynamics. The theories and principles are then brought together in a final synthesis onadaptation.The book''s unique approach unites genetic, development, and environmental influences into a single comprehensive treatment of the eco-evolutionary process.

The theme of the book is the distribution and abundance of organisms in space and time. The core of the book lies in how local births and deaths are tied to emigration and immigration processes, and how environmental variability at different scales affects population dynamics with stochastic processes and spatial structure and shows how elementary analytical tools can be used to understand population fluctuations, synchrony, processes underlying range distributions and community structure and species coexistence. The book also shows how spatial population dynamics models can be used to understand life history evolution and aspects of evolutionary game theory. Although primarily based on analytical and numerical analyses of spatial population processes, data from several study systems are also dealt with.

A book blending evolution and trophic dynamics, taking into account recent advances in both behavioral and population ecology, is long overdue. A central objective of this book is to consider whether adaptive behavioral decisions on the individual organism level might tend to stabilize trophic interactions. A second major goal of the book is to explore the implications of presumably adaptive behaviors on trophic dynamics and the implications of trophic dynamics for the evolution of adaptive behaviors. All evolutionary biologists, ecologists, and behavioral ecologists should find this exciting volume essential reading.

The nemerteans are a fascinating, common and often locally abundant group of invertebrates, yet for long have attracted the attention of only a handful of scientists. In recent years, however, increasing numbers of people have developed diverse research interests in the group with the result that our knowledge of these worms has rapidly advanced. Clearly there is a need for a regular series of international meetings where individuals working on these animals can meet to exchange ideas, review developments concerning nemertean biology and freely discuss future proposals. The first such meeting was held in Philadelphia during December 1983. Twenty-seven scientists from eight countries participated in the Second International Meeting on Nemertean Biology, held at the Tjarno Marine Biological Laboratory, Sweden, 11-15 August 1986. The meeting was divid­ ed into five sessions: two dealt with ecological studies, two with nemertean taxonomy, and the final session covered aspects of general biology. A total of 26 papers was presented; four, by N. Anadem, G. Berg, 1. Bierne, and 1.M. TurbeviIIe, were for different reasons not submitted for inclusion in this volume. Three additional presentations were made on behalf of B. Kulikova, E. N. WiIImer, and Z. Yin, all of whom were unable to participate in the meeting.

Samtiden tycks besatt av det ögonblickliga: I kultur, politik och samhällsdebatt överdrivs individuella prestationer och snabba, omvälvande händelser. Detta trots att samhällsvetenskapen sedan länge har understrukit betydelsen av historiska utvecklingslinjer, och gång på gång visat att beslut idag är starkt präglade av tidigare händelser. Med andra ord: att samhällsutvecklingen är spårbunden.I denna bok samlas essäer av forskare, i allt från statsvetenskap och sociologi till språkvetenskap och stadsbyggnad, som alla undersöker spårbundenhet inom sina respektive discipliner . Boken ger begreppet spårbundenhet en välbehövlig renässans i en tid av kortsiktighet och synbar historielöshet.Olof Hallonsten är docent i sociologi och universitetslektor vid Ekonomihögskolan vid Lunds universitet. Hans forskning rör främst teoretiska och historiska perspektiv på samhällsutveckling.Anna Persson är docent i statsvetenskap och verksam som forskare och universitetslektor vid Statsvetenskapliga institutionen, Göteborgs universitet. Hennes forskning är inriktad mot jämförande politik och politisk ekonomi med särskilt fokus på hur formella och informella institutioner påverkar och samspelar med staters kapacitet inom centrala utvecklingsområden så som korruption, beskattning och välfärd.

In any scientific discipline, meetings with presented papers and discussions are the most effective stimulus to the advancement of knowledge. Nemerteans have long been largely neglected because their taxonomy is difficult: the need for histological study of serial sections has proved inhibiting to most zoologists. During the last twenty years, however, this intriguing phylum has attracted the attention both of increasing numbers of taxonomists as well as of workers interested in many aspects of, for example, their ecology, evolution, physiology and fine structure. The enthusiam stemming from the First International Meeting held in Philadelphia during December 1983 made it abudantly clear that regular meetings of this type should be continued. The Second, at the Tjärnö Marine Biological Laboratory in Sweden (August 1986), emphasized the importance of such international gatherings. The Third Meeting was held in Britain, at Y Coleg Normal, Bangor, North Wales, August 10--15, 1991, with 24 participants from six countries. This volume records most of the papers given at the conference.
