The most comprehensive reference on Mexico's diverse mammalian fauna. Mammals of Mexico is the first reference book in English on the more than 500 types of mammal species found in the diverse Mexican habitats, which range from the Sonoran Desert to the Chiapas cloud forests. The authoritative species accounts are written by a Who’s Who of experts compiled by famed mammalogist and conservationist Gerardo Ceballos. Ten years in the making, Mammals of Mexico covers everything from obscure rodents to whales, bats, primates, and wolves. It is thoroughly illustrated with color photographs and meticulous artistic renderings, as well as range maps for each species. Introductory chapters discuss biogeography, conservation, and evolution. The final section of the book illustrates the skulls, jaws, and tracks of Mexico’s mammals. This unparalleled collection of scientific information on, and photographs of, Mexican wildlife belongs on the shelf of every mammalogist, in public and academic libraries, and in the hands of anyone curious about Mexico and its wildlife.
On the outskirts of the Milky Way, floating slowly through space, there hangs a planet unlike any other. It has oceans, deserts, jungles and mountains. It has life that swims, life that soars and life that swings through the trees. It is a place of dazzling variety and infinite wonder - and it's the only world we've got. Climate change is happening, now. But it's not too late to change the story. Meet the humans, from around the world, who are fighting to save our planet. This is your call to arms. Featuring 25 hopeful stories including Greta Thunberg, David Attenborough, Jane Goodall, Wangari Maathai - as well as lesser-known heroes, such as turtle-protector Len Peters, the guardians of the...

While the Spanish conquistadors have been stereotyped as rapacious treasure seekers, many firstcomers to the New World realized that its greatest wealth lay in the native populations whose labor could be harnessed to build a new Spain. Hence, the early arrivals in Mexico sought encomiendas—"a grant of the Indians of a prescribed indigenous polity, who were to provide the grantee (the encomendero) tribute in the form of commoditiesand service in return for protection and religious instruction." This study profiles the 506 known encomenderos in New Spain (present-day Mexico) during the years 1521-1555, using their life histories to chart the rise, florescence, and decline of the encomienda system. The first part draws general conclusions about the actual workings of the encomienda system. The second part provides concise biographies of the encomenderos themselves.
The tropics and subtropics are home to about 75% of the global human population. Cultural, economic, and political circumstances vary enormously across this vast geography of some 170 countries and territories. The regions not only harbor the world's poorest countries but their human populations are growing disproportionally faster than in temperate zones. Some countries are developing rapidly -- Brazil, China, India, and Mexico being obvious examples, while others still remain in the poverty trap. This region contains an astonishing proportion of global biodiversity; some 90% of plant and animal species by some measures. Its contribution to human well-being is astounding. It was the birthpl...
With more than 1,400 species, bats are an incredibly diverse and successful group of mammals that can serve as model systems for many unique evolutionary adaptations. Flight has allowed them to master the sky, while echolocation enables them to navigate in the dark. Being small, secretive, nocturnal creatures has made bats a challenge to study, but over the past 50 years, innovative research has made it possible to dispel some of the mystery and myth surrounding them to give us a better understanding of the role these animals play in the ecosystem. The structure of the book is based on several broad themes across the biological sciences, including the evolution of bats, their ecology and behavior, and conservation of biodiversity. Within these themes are more specific topics on important aspects of bat research, such as morphology, molecular biology, echolocation, taxonomy, systematics, threats to bats, social structure, reproduction, movements, and feeding strategies. Given its scope, the book will appeal to the wider scientific community, environmental organizations, and government policymakers who are interested in the interdisciplinary aspects of biology and nature.
