In diesem Buch erfahren Sie, welchen Beitrag die Biowissenschaften bei der Untersuchung und Aufklärung von Straftaten leisten. Für diese zweite Auflage durchgängig überarbeitet und aktualisiert, erfasst der Band in ausgewogener Mischung alle Organismen, die in der Forensik eine Rolle spielen: Wirbellose, Wirbeltiere, Pflanzen und Mikroben.
In der Neuauflage finden Sie mehr Informationen über molekulare Methoden, außerdem wurde das Material über Bioterrorismus und Forensik in der freien Natur ausgebaut. Neben der Erläuterung neuer Identifikationsmethoden mit DNA und RNA wird auch über ethische Fragen des Unterhalts von DNA-Datenbanken diskutiert.
