This book investigates the mathematical analysis of biological invasions. Unlike purely qualitative treatments of ecology, it draws on mathematical theory and methods, equipping the reader with sharp tools and rigorous methodology. Subjects include invasion dynamics, species interactions, population spread, long-distance dispersal, stochastic effects, risk analysis, and optimal responses to invaders. While based on the theory of dynamical systems, including partial differential equations and integrodifference equations, the book also draws on information theory, machine learning, Monte Carlo methods, optimal control, statistics, and stochastic processes. Applications to real biological invasions are included throughout. Ultimately, the book imparts a powerful principle: that by bringing ecology and mathematics together, researchers can uncover new understanding of, and effective response strategies to, biological invasions. It is suitable for graduate students and established researchers in mathematical ecology.
Religious Architecture in Latium and Etruria, c. 900-500 BC presents the first comprehensive treatment of cult buildings in western central Italy from the Iron Age to the Archaic Period. By analysing the archaeological evidence for the form of early religious buildings and their role in ancient communities, it reconstructs a detailed history of early Latial and Etruscan religious architecture that brings together the buildings and the people who used them. The first part of the study examines the processes by which religious buildings changed from huts and shrines to monumental temples, and explores apparent differences between these processes in Latium and Etruria. The second part analyses the broader architectural, religious, and topographical contexts of the first Etrusco-Italic temples alongside possible rationales for their introduction. The result is a new and extensive account of when, where, and why monumental cult buildings became features of early central Italic society.
