Book Description
Tropical geometry is a combinatorial shadow of algebraic geometry, offering new polyhedral tools to compute invariants of algebraic varieties. It is based on tropical algebra, where the sum of two numbers is their minimum and the product is their sum. This turns polynomials into piecewise-linear functions, and their zero sets into polyhedral complexes. These tropical varieties retain a surprising amount of information about their classical counterparts. Tropical geometry is a young subject that has undergone a rapid development since the beginning of the 21st century. While establishing itself as an area in its own right, deep connections have been made to many branches of pure and applied mathematics. This book offers a self-contained introduction to tropical geometry, suitable as a course text for beginning graduate students. Proofs are provided for the main results, such as the Fundamental Theorem and the Structure Theorem. Numerous examples and explicit computations illustrate the main concepts. Each of the six chapters concludes with problems that will help the readers to practice their tropical skills, and to gain access to the research literature. This wonderful book will appeal to students and researchers of all stripes: it begins at an undergraduate level and ends with deep connections to toric varieties, compactifications, and degenerations. In between, the authors provide the first complete proofs in book form of many fundamental results in the subject. The pages are sprinkled with illuminating examples, applications, and exercises, and the writing is lucid and meticulous throughout. It is that rare kind of book which will be used equally as an introductory text by students and as a reference for experts. —Matt Baker, Georgia Institute of Technology Tropical geometry is an exciting new field, which requires tools from various parts of mathematics and has connections with many areas. A short definition is given by Maclagan and Sturmfels: “Tropical geometry is a marriage between algebraic and polyhedral geometry”. This wonderful book is a pleasant and rewarding journey through different landscapes, inviting the readers from a day at a beach to the hills of modern algebraic geometry. The authors present building blocks, examples and exercises as well as recent results in tropical geometry, with ingredients from algebra, combinatorics, symbolic computation, polyhedral geometry and algebraic geometry. The volume will appeal both to beginning graduate students willing to enter the field and to researchers, including experts. —Alicia Dickenstein, University of Buenos Aires, Argentina

Book Description
Biodiversity has been a key concept in international conservation since the 1980s, yet historians have paid little attention to its origins. Uncovering its roots in tropical fieldwork and the southward expansion of U.S. empire at the turn of the twentieth century, Megan Raby details how ecologists took advantage of growing U.S. landholdings in the circum-Caribbean by establishing permanent field stations for long-term, basic tropical research. From these outposts of U.S. science, a growing community of American "tropical biologists" developed both the key scientific concepts and the values embedded in the modern discourse of biodiversity. Considering U.S. biological fieldwork from the era of the Spanish-American War through the anticolonial movements of the 1960s and 1970s, this study combines the history of science, environmental history, and the history of U.S.–Caribbean and Latin American relations. In doing so, Raby sheds new light on the origins of contemporary scientific and environmentalist thought and brings to the forefront a surprisingly neglected history of twentieth-century U.S. science and empire.

Book Description
An engaging portrait of a community of biologists, The Tapir's Morning Bathis a behind-the-scenes account of life at a tropical research station that"conveys the uncertainties, frustrations, and joys of [scientific] fieldwork" (Science). On Panama's Barro Colorado Island, Elizabeth Royte worksalongside the scientists -- counting seeds, sorting insects, collectingmonkey dung, radiotracking fruit bats -- as they struggle to parse theintricate workings of the tropical rain forest. While showing the humanside of the scientists at work, Royte explores the tensions between the slow pace of basic research and the reality of a world that may not have time to wait for answers.

Book Description
The goal of this book is to explain, at the graduate student level, connections between tropical geometry and optimization. Building bridges between these two subject areas is fruitful in two ways. Through tropical geometry optimization algorithms become applicable to questions in algebraic geometry. Conversely, looking at topics in optimization through the tropical geometry lens adds an additional layer of structure. The author covers contemporary research topics that are relevant for applications such as phylogenetics, neural networks, combinatorial auctions, game theory, and computational complexity. This self-contained book grew out of several courses given at Technische Universität Berlin and elsewhere, and the main prerequisite for the reader is a basic knowledge in polytope theory. It contains a good number of exercises, many examples, beautiful figures, as well as explicit tools for computations using $texttt{polymake}$.

Book Description
Quaint cottage meets tropical paradise in this delightful consideration of the homes, gardens, and interiors of "The Grove." Coconut Grove is a seaside hideaway filled with modest homes and charming cottages that have been nurtured, preserved, and artfully updated for today. Houses washed with white set amidst abundant gardens recall Eden. Irregular rooflines fitted with earthy red tile emerge playfully from an abundance of bright bougainvillea and graceful palms. Fountains splash playfully within cozy courtyards. Within these homes--small cracker cottages, stone bungalows, Mediterranean casitas, and Caribbean-styled ranches--light, bright colors and cool tile floors offer solace from the blazing afternoon rays of the sun. A haven for those drawn to eclectic architecture and a welcoming atmosphere, the cottages of Coconut Grove are both the realization of the tropical domestic dream and an expression of a lifestyle marked by quiet joys. Here, for the first time in brilliant new photography specifically commissioned for the book, are the finest and most intriguing cottages of this special place--an unprecedented tour and invitation given by architecture authority and Miami resident Beth Dunlop and Coconut Grove-based photographer Claudia Uribe.

Book Description
A deeply reported personal investigation by a Miami journalist examines the present and future effects of climate change in the Magic City -- a watery harbinger for coastal cities worldwide. Miami, Florida, is likely to be entirely underwater by the end of this century. Residents are already starting to see the effects of sea level rise today. From sunny day flooding caused by higher tides to a sewer system on the brink of total collapse, the city undeniably lives in a climate changed world. In Disposable City, Miami resident Mario Alejandro Ariza shows us not only what climate change looks like on the ground today, but also what Miami will look like 100 years from now, and how that future has been shaped by the city's racist past and present. As politicians continue to kick the can down the road and Miami becomes increasingly unlivable, real estate vultures and wealthy residents will be able to get out or move to higher ground, but the most vulnerable communities, disproportionately composed of people of color, will face flood damage, rising housing costs, dangerously higher temperatures, and stronger hurricanes that they can't afford to escape. Miami may be on the front lines of climate change, but the battle it's fighting today is coming for the rest of the U.S. -- and the rest of the world -- far sooner than we could have imagined even a decade ago. Disposable City is a thoughtful portrait of both a vibrant city with a unique culture and the social, economic, and psychic costs of climate change that call us to act before it's too late.

Book Description
Tropical Stream Ecology describes the main features of tropical streams and their ecology. It covers the major physico-chemical features, important processes such as primary production and organic-matter transformation, as well as the main groups of consumers: invertebrates, fishes and other vertebrates. Information on concepts and paradigms developed in north-temperate latitudes and how they do not match the reality of ecosystems further south is expertly addressed. The pressing matter of conservation of tropical streams and their biodiversity is included in almost every chapter, with a final chapter providing a synthesis on conservation issues. For the first time, Tropical Stream Ecology places an important emphasis on viewing research carried out in contributions from international literature. - First synthetic account of the ecology of all types of tropical streams - Covers all of the major tropical regions - Detailed consideration of possible fundamental differences between tropical and temperate stream ecosystems - Threats faced by tropical stream ecosystems and possible conservation actions - Descriptions and synstheses life-histories and breeding patterns of major aquatic consumers (fishes, invertebrates)
