• Sommario/riassunto: The origin of biological diversity, via the formation of new species, can be inextricably linked to adaptation to the ecological environment. Specifically, ecological processes are central to the formation of new species when barriers to gene flow (reproductive isolation) evolve between populations as a result of ecologically-based divergent natural selection. This process of 'ecological speciation' has seen a large body of particularly focused research in the last 10-15 years, anda review and synthesis of the theoretical and empirical literature is now timely.The book begins by clarifying wha

• Sommario/riassunto: Die Wiedervereinigung veränderte Deutschland nicht nur im Inneren, sondern wirkte sich auch in hohem Maße auf die deutsche Stellung in Europa und in der Welt aus. Die neuen Rahmenbedingungen sowie der ; Generationswechsel in der Politik führten in den Folgejahren zu einer Veränderung der deutschen Selbstdarstellung. All dies blieb nicht ohne Folgen auf ihre Wahrnehmung im Ausland. Der promovierte Historiker Jean-Samuel Marx untersucht in diesem Band die Selbstdarstellung und die Rezeption des wiedervereinigten Deutschlands in Frankreich seit 1990. Dabei arbeitet er heraus, anhand welcher Faktoren diese Entwicklungen zu erklären sind und inwiefern die Selbstdarstellung der Bundesrepublik und ihre Rezeption miteinander korrelieren.
