Ancient lakes are exceptional freshwater environments that have continued to exist for hundreds of thousands of years. They have long been recognized as centres of biodiversity and hotspots of evolution. During recent decades, speciation in ancient lakes has emerged as an important and exciting topic in evolutionary biology.The contributions in this volume deal with patterns and processes of biological diversification in three prominent ancient lake systems. Of these, the famous East African Great Lakes already have a strong tradition of evolutionary studies, but the two other systems have so far received much less attention. The exceptional biodiversity of the European sister lakes Ohrid and Prespa of the Balkans has long been known, but has largely been neglected in the international literature until recently. The rich biota and problems of its evolution in the two central lake systems on the Indonesian island of Sulawesi, in turn, have only lately started to draw scientific attention.This volume aims at deepening the awareness of the unusual biological diversity in ancient lakes in general, and of the role of these lakes as natural laboratories for the study of speciation and diversification in particular. It should stimulate further research that will lead to a better understanding of key evolutionary processes in these lakes, and to knowledge that might help in mitigating the deterioration of their diversity in the future.

Zu diesem Zweck bietet das vorliegende Buch eine Vielzahl von Aufgaben mit Lösungen zu den für die Wirtschaftswissenschaften wichtigen mathematischen Themen. Die konkrete inhaltliche Ausgestaltung der Aufgaben und Lösungen macht das Buch aber auch unabhängig vom Lehrwerk zu einem nützlichen Studienbegleiter.

Der moderne Wirtschaftswissenschaftler hat profunde Kenntnisse der Mathematik. Mit Hilfe mathematischer Methoden werden heute etwa Optionsscheine an der Börse bewertet oder Auktionen entworfen. Zudem bildet die Mathematik die Basis für empirisches Arbeiten mit Hilfe statistischer Methoden. In allen Arbeitsfeldern des Ökonomen ist somit eine gute ökonomische Intuition gepaart mit mathematischem Sachverstand unerlässlich geworden. Im Unterschied zu vielen anderen Lehrbüchern beschränkt sich dieses Buch nicht auf die Besprechung der verschiedenen Methoden und auf ein reines Aufreihen der verschiedenen Regeln und Theoreme. Vielmehr beweisen die Autoren die wichtigsten Aussagen, um dem Leser ein Verständnis für die Richtigkeit mathematischer Aussagen und Beweistechniken zu vermitteln. Des Weiteren werden alle mathematischen Methoden auch an Hand von ökonomischen Beispielen verdeutlicht.

Real world investors differ in their tastes and attitudes and they do not have, in general, perfect information about the future prospects of the economy. Most theoretical models, however, assume to the contrary that investors are homogeneous and perfectly informed about the market. In this book, an attempt is made to overcome these shortcomings. In three different case studies, the effect of heterogeneous time preferences, heterogeneous beliefs and imperfect information about the economy's growth on the term structure of interest rates are studied. The initial chapter gives an introduction to the theory of financial markets in continuous time under imperfect information and establishes the existence of an equilibrium with complete markets.
