When migrating birds and other creatures move along a path of plant communities in bloom, they follow what has come to be known as a nectar trail. Should any of these plants be eliminated from the sequence—whether through habitat destruction, pests, or even aberrant weather—the movement of these pollinators may be interrupted and their very survival threatened. In recent efforts by ecologists and activists to envision a continental-scale network of protected areas connected by wildlife corridors, the peculiar roles of migratory pollinators which travel the entire length of this network cannot be underestimated in shaping the ultimate conservation design. This book, a unique work of comparative zoogeography and conservation biology, is the first to bring together studies of these important migratory pollinators and of what we must do to conserve them. It considers the similarities and differences among the behavior and habitat requirements of several species of migratory pollinators and seed dispersers in the West—primarily rufous hummingbirds, white-winged doves, lesser long-nosed bats, and monarch butterflies. It examines the population dynamics of these four species in flyways that extend from the Pacific Ocean to the continental backbone of the Sierra Madre Oriental and Rocky Mountains, and it investigates their foraging and roosting behaviors as they journey from the Tropic of Cancer in western Mexico into the deserts, grasslands, and thornscrub of the U.S.-Mexico borderlands. The four pollinators whose journeys are traced here differ dramatically from one another in foraging strategies and stopover fidelities, but all challenge many of the truisms that have emerged regarding the status of migratory species in general. The rufous hummingbird makes the longest known avian migration in relation to body size and is a key to identifying nectar corridors running through northwestern Mexico to the United States. And there is new evidence to challenge the long-supposed separation of eastern and western monarch butterfly populations by the Rocky Mountains as these insects migrate. Conserving Migratory Pollinators and Nectar Corridors in Western North America demonstrates new efforts to understand migratory species and to determine whether their densities, survival rates, and health are changing in response to changes in the distribution and abundance of nectar plants found within their ranges. Representing collaborative efforts that bridge field ecology and conservation biology in both theory and practice, it is dedicated to safeguarding dynamic interactions among plants and pollinators that are only now being identified.

Pollinators-insects, birds, bats, and other animals that carry pollen from the male to the female parts of flowers for plant reproduction-are an essential part of natural and agricultural ecosystems throughout North America. For example, most fruit, vegetable, and seed crops and some crops that provide fiber, drugs, and fuel depend on animals for pollination. This report provides evidence for the decline of some pollinator species in North America, including America's most important managed pollinator, the honey bee, as well as some butterflies, bats, and hummingbirds. For most managed and wild pollinator species, however, population trends have not been assessed because populations have not been monitored over time. In addition, for wild species with demonstrated declines, it is often difficult to determine the causes or consequences of their decline. This report outlines priorities for research and monitoring that are needed to improve information on the status of pollinators and establishes a framework for conservation and restoration of pollinator species and communities.

In the borderlands between the United States and Mexico, America's largest cat—the jaguar—is fighting to regain its kingdom. Added to the endangered species list in 1997, the jaguar has declined in population mainly due to habitat fragmentation created by roads, farms, mines, and most controversially, the border wall. Such human-made barriers prevent free movement of many wild animals for predation and mating, thereby threatening their reproduction, DNA transfer, and overall survival. Author and wildlife biologist Elizabeth Webb examines the jaguar's predicament and highlights the work of field scientists who are searching for solutions. "Conservation Connection" features throughout the book underscore the importance of protecting this keystone species of the Americas.

Lizards dashing rapidly between plants. Songbirds and woodpeckers flying to and from their nests. Hawks perched on saguaros. What kinds of journeys have these and many other animals and plants and their ancestors taken in space and time to arrive in the Sonoran Desert? How long have these species been living together here? In Sonoran Desert Journeys ecologist Theodore H. Fleming discusses two remarkable journeys. First, Fleming offers a brief history of our intellectual and technical journey over the past three centuries to understand the evolution of life on Earth. Next, he applies those techniques on a journey of discovery about the evolution and natural history of some of the Sonoran Desert’s most iconic animals and plants. Fleming details the daily lives of a variety of reptiles, birds, mammals, and plants, describing their basic natural and evolutionary histories and addressing intriguing issues associated with their lifestyles and how they cope with a changing climate. Finally, Fleming discusses the complexity of Sonoran Desert conservation. This book explores the evolution and natural history of iconic animals and plants of the northern Sonoran Desert through the eyes of a curious naturalist and provides a model of how we can coexist with the unique species that call this area home.

Recent advances in the study of bats have changed the way we understand this illusive group of mammals. This volume consist of 25 chapters and 57 authors from around the globe all writing on the most recent finding on the evolution, ecology and conservation of bats. The chapters in this book are not intended to be exhaustive literature reviews, but instead extended manuscripts that bring new and fresh perspectives. Many chapters consist of previously unpublished data and are repetitive of new insights and understanding in bat evolution, ecology and conservation. All chapters were peer-reviewed and revised by the authors. Many of the chapters are multi-authored to provide comprehensive and authoritative coverage of the topics.

The average kilometer of tropical rainforest is teeming with life; it contains thousands of species of plants and animals. As The Ornaments of Life reveals, many of the most colorful and eye-catching rainforest inhabitants—toucans, monkeys, leaf-nosed bats, and hummingbirds to name a few—are an important component of the infrastructure that supports life in the forest. These fruit-and-nectar eating birds and mammals pollinate the flowers and disperse the seeds of hundreds of tropical plants, and unlike temperate communities, much of this greenery relies exclusively on animals for reproduction. Synthesizing recent research by ecologists and evolutionary biologists, Theodore H. Fleming and W. John Kress demonstrate the tremendous functional and evolutionary importance of these tropical pollinators and frugivores. They shed light on how these mutually symbiotic relationships evolved and lay out the current conservation status of these essential species. In order to illustrate the striking beauty of these “ornaments” of the rainforest, the authors have included a series of breathtaking color plates and full-color graphs and diagrams.

This book is a state-of-the-art compilation of the latest information on ecosystem services of agroforestry. The last two decades have seen a surge in literature on the ecosystem services of sustainable agriculture practices, including that of agroforestry; however, compilation and synthesis of such information from agroforestry have been limited. This book fills that void by bringing in a number of experts from around the world. In addition to presenting the multiple dimensions of ecosystem services provided by major agroforestry practices, the book also offers case studies from both tropical and temperate regions of the world. Information from this book can be used to design land management practices for climate change mitigation, ecosystem benefits, agricultural productivity and sustainability, and for survival and profitability of family farms and to conserve biodiversity. While synthesizing information of the biophysical aspects of ecosystem services, the book also outlines the socioeconomic and policy dimensions, including appropriate incentive models to enhance adoption of agroforestry so that society at large can enjoy these important benefits
