Lake Ladoga is the largest lake in Europe and, with its surface of 17,891 km2 and volume of 837 km3, it ranks among the top fifteen of the world's freshwater bodies. The ecological condition of Lake Ladoga is of concern to several million people living in its surroundings. There is evidence of water quality degradation and gradual eutrophication of the lake during the past decades; on the other hand, pollution control measures have improved the situation in many of the most polluted sites near industrial effluent sources. The first international Lake Ladoga Symposium was held in St. Petersburg on 22-26 November, 1993. The symposium was attended by 160 scientists, and about half of the papers presented at the symposium have been edited for this book. The contributions are grouped under the following headings: Present state of Lake Ladoga; Hydrodynamics of Lake Ladoga and other large water bodies; Water quality and pollution; Ecological studies of Lake Ladoga biota; History of Lake Ladoga and rates of change in its environment; Research methods for large lakes. Besides providing up-to-date information on the state of the lake, the papers deal with studies of many other large lakes of the cold-temperature zone and the general problems and methods of large lake research. Furthermore, the book is a valuable source of reference to the voluminous Russian limnological literature.

Our knowledge of Ukrainian bark and ambrosia beetles (Coleoptera: Curculionidae: Scolytinae and Platypodinae) is summarized as a baseline for future studies of the fauna, with a checklist including information on distribution, host trees, biology and taxonomy. One hundred twenty-two species are recorded from Ukraine, of which seven are recorded for the first time. One species is recorded for the first time from Europe. Previous records of 24 species are considered dubious and requiring confirmation. In contrast to the Palaearctic Catalogue (Knížek 2011b), we consider Anisandrus maiche to be first described by Kurentsov (1941) rather than by Eggers (1942); A. maiche (Eggers, 1942) is a junior synonym of A. maiche(Kurentsov, 1941).

Linear differential equations with periodic coefficients constitute a well developed part of the theory of ordinary differential equations [17, 94, 156, 177, 178, 272, 389]. They arise in many physical and technical applications [177, 178, 272]. A new wave of interest in this subject has been stimulated during the last two decades by the development of the inverse scattering method for integration of nonlinear differential equations. This has led to significant progress in this traditional area [27, 71, 72, 111 119, 250, 276, 277, 284, 286, 287, 312, 313, 337, 349, 354, 392, 393, 403, 404]. At the same time, many theoretical and applied problems lead to periodic partial differential equations. We can mention, for instance, quantum mechanics [14, 18, 40, 54, 60, 91, 92, 107, 123, 157-160, 192, 193, 204, 315, 367, 412, 414, 415, 417], hydrodynamics [179, 180], elasticity theory [395], the theory of guided waves [87-89, 208, 300], homogenization theory [29, 41, 348], direct and inverse scattering [175, 206, 216, 314, 388, 406-408], parametric resonance theory [122, 178], and spectral theory and spectral geometry [103 105, 381, 382, 389]. There is a sjgnificant distinction between the cases of ordinary and partial differential periodic equations. The main tool of the theory of periodic ordinary differential equations is the so-called Floquet theory [17, 94, 120, 156, 177, 267, 272, 389]. Its central result is the following theorem (sometimes called Floquet-Lyapunov theorem) [120, 267].

The Aral Sea Basin, which is located in the central Asian part of the former Soviet Union, is undergoing dramatically rapid and intense environmental change. Pervasive human misuse and overuse of its water, land, and other critical natural resources have led to severe degradation of key ecological systems. This book analyses the environmental, human and economic problems that have arisen and presents recommendations for future research needs. Primary focus is on the drying of the Aral Sea, but related issues of diminished river flow, land and water pollution, and degradation, ecosystem deterioration, and adverse effects on humans are also examined.

A renewed interest in chronological problems has surfaced in recent years. In this volume deriving from the first international Conference of the Danish National Research Foundation's Centre for Black Sea Studies, thirteen contributions by scholars from Russia, Ukraine, Romania, USA, Canada, Belgium and Denmark review and discuss the elements upon which the chronology used in Black Sea archaeology and history in the period c. 400-100 BC is built. The subjects include: amphora and amphora stamp chronologies (Mark Lawall; Sergej Ju. Monachov; Niculae Conovici; Vladimir Stolba), coin chronology (Francois de Callatay, Athenian pottery (Susan I. Rotroff), epigraphic evidence (Jakob Munk Hojte), and a number of case studies presenting the material on which is based the dating of a series of Greek and barbarian/non-Greek sites and burial monuments on the northern shores of the Black Sea (Valentina V. Krapivina; Valeria Bylkova; Lise Hannestad, Miron I. Zolotarev, Ju. P. Zaytsev, Valentina I. Mordvinceva). VLADIMIR STOLBA is Senior Researcher at The Institute of the History of Material Culture, Russian Academy of Science, St Petersburg, and presently at the Centre for Black Sea Studies, Aarhus. LISE HANNESTAD is Senior Associate Professor at the Department for Classical Archaeology, University of Aarhus.
