Up-to-date field guide to the birds of Colombia, all 1,934 species and counting. To facilitate rapid identification, this portable field guide includes accurate illustrations of species and subspecies on 212 plates, shown next to practical information about distribution, behaviour, endemism, and global/national threat levels.

From basic algebraic structures to cryptography, arithmetic with elliptic curves, and automata - this textbook contains a modern introduction to discrete algebraic methods as required by mathematicians and computer scientists in the age of the internet. It lays foundations for theoretical computer science and is suitable for master students with a basic background in mathematics.

The idea behind this book is to provide the mathematical foundations for assessing modern developments in the Information Age. It deepens and complements the basic concepts, but it also considers instructive and more advanced topics. The treatise starts with a general chapter on algebraic structures; this part provides all the necessary knowledge for the rest of the book. The next chapter gives a concise overview of cryptography. Chapter 3 on number theoretic algorithms is important for developping cryptosystems, Chapter 4 presents the deterministic primality test of Agrawal, Kayal, and Saxena. The account to elliptic curves again focuses on cryptographic applications and algorithms. With combinatorics on words and automata theory, the reader is introduced to two areas of theoretical computer science where semigroups play a fundamental role.The last chapter is devoted to combinatorial group theory and its connections to automata. Contents: Algebraic structures Cryptography Number theoretic algorithms Polynomial time primality test Elliptic curves Combinatorics on words Automata Discrete infinite groups.

Thunder rolled across the prairie - and then there was silence...It was probably more than 30 million American bison roaming the plains of the Midwest. Nothing was more powerful in the prairie, neither physically nor spiritually. With the arrival of the European settlers massive slaughter began. The (hi)story of the bison is a parable about globalisation and the interplay of technological progress, capitalism, and a lack of understanding of ecological contexts. The prairie vanished with the bison. Now the bison returns. And this is not nostalgia. The bison is a real existing and socio-cultural phenomenon. It is a current political issue in the dispute between cattle breeders and the bison lobby. The photographers travelled through the centre of the bison country, from North and South Dakota, Wyoming, Colorado, to Montana. The magical black-and-white photographs of the bison translate the vision into reality. Buffalo Ballad is an homage to the American soul, with captivating images that are like the bison itself: unique, powerful and magical.

This volume comprises a carefully selected collection of articles emerging from and pertinent to the 2010 CFL-80 conference in Rio de Janeiro, celebrating the 80th anniversary of the Courant-Friedrichs-Lewy (CFL) condition. A major result in the field of numerical analysis, the CFL condition has influenced the research of many important mathematicians over the past eight decades, and this work is meant to take stock of its most important and current applications. The Courant-Friedrichs-Lewy (CFL) Condition: 80 Years After its Discovery will be of interest to practicing mathematicians, engineers, physicists, and graduate students who work with numerical methods.
