Book Description
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.

American Jaguar

American Jaguar PDF Author: Elizabeth Webb
Publisher: Twenty-First Century Books ™
ISBN: 1541572203
Category : Young Adult Nonfiction
Languages : en
Pages : 121

Book Description
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.

Status of Pollinators in North America

Status of Pollinators in North America PDF Author: National Research Council
Publisher: National Academies Press
ISBN: 0309102898
Category : Technology & Engineering
Languages : en
Pages : 327

Book Description
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.

ISBN: 0816547300
Category : Nature
Languages : en
Pages : 337

Book Description
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.

No Species Is an Island

No Species Is an Island PDF Author: Theodore H. Fleming
Publisher: University of Arizona Press
ISBN: 0816537550
Category : Nature
Languages : en
Pages : 81

Book Description
In the darkness of the star-studded desert, bats and moths feed on the nectar of night-blooming cactus flowers. By day, birds and bees do the same, taking to blooms for their sweet sustenance. In return these special creatures pollinate the equally intriguing plants in an ecological circle of sustainability. The Sonoran Desert is the most biologically diverse desert in the world. Four species of columnar cacti, including the iconic saguaro and organ pipe, are among its most conspicuous plants. No Species Is an Island describes Theodore H. Fleming’s eleven-year study of the pollination biology of these species at a site he named Tortilla Flats in Sonora, Mexico, near Kino Bay. Now Fleming shares the surprising results of his intriguing work. Among the novel findings are one of the world’s rarest plant-breeding systems in a giant cactus; the ability of the organ pipe cactus to produce fruit with another species’ pollen; the highly specialized moth-cactus pollination system of the senita cactus; and the amazing lifestyle of the lesser long-nosed bat, the major nocturnal pollinator of three of these species. These discoveries serve as a primer on how to conduct ecological research, and they offer important conservation lessons for us all. Fleming highlights the preciousness of the ecological web of our planet—Tortilla Flats is a place where cacti and migratory bats and birds connect such far-flung habitats as Mexico’s tropical dry forest, the Sonoran Desert, and the temperate rain forests of southeastern Alaska. Fleming offers an insightful look at how field ecologists work and at the often big surprises that come from looking carefully at a natural world where no species stands alone.

The Ornaments of Life

ISBN: 022602332X
Category : Science
Languages : en
Pages : 615

Book Description
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.
