Download or read book Monarchs in a Changing World written by Karen S. Oberhauser and published by Cornell University Press. This book was released on 2015-11-16 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: Monarch butterflies are among the most popular insect species in the world and are an icon for conservation groups and environmental education programs. Monarch caterpillars and adults are easily recognizable as welcome visitors to gardens in North America and beyond, and their spectacular migration in eastern North America (from breeding locations in Canada and the United States to overwintering sites in Mexico) has captured the imagination of the public. Monarch migration, behavior, and chemical ecology have been studied for decades. Yet many aspects of monarch biology have come to light in only the past few years. These aspects include questions regarding large-scale trends in monarch population sizes, monarch interactions with pathogens and insect predators, and monarch molecular genetics and large-scale evolution. A growing number of current research findings build on the observations of citizen scientists, who monitor monarch migration, reproduction, survival, and disease. Monarchs face new threats from humans as they navigate a changing landscape marked by deforestation, pesticides, genetically modified crops, and a changing climate, all of which place the future of monarchs and their amazing migration in peril. To meet the demand for a timely synthesis of monarch biology, conservation and outreach, Monarchs in a Changing World summarizes recent developments in scientific research, highlights challenges and responses to threats to monarch conservation, and showcases the many ways that monarchs are used in citizen science programs, outreach, and education. It examines issues pertaining to the eastern and western North American migratory populations, as well as to monarchs in South America, the Pacific and Caribbean Islands, and Europe. The target audience includes entomologists, population biologists, conservation policymakers, and K–12 teachers.

Download or read book The Ecological Basis of Conservation written by Steward Pickett and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 477 pages. Available in PDF, EPUB and Kindle. Book excerpt: From its inception, the U.S. Department of the Interior has been charged with a conflicting mission. One set of statutes demands that the department must develop America's lands, that it get our trees, water, oil, and minerals out into the marketplace. Yet an opposing set of laws orders us to conserve these same resources, to preserve them for the long term and to consider the noncommodity values of our public landscape. That dichotomy, between rapid exploitation and long-term protection, demands what I see as the most significant policy departure of my tenure in office: the use of science-interdisciplinary science-as the primary basis for land management decisions. For more than a century, that has not been the case. Instead, we have managed this dichotomy by compartmentalizing the American landscape. Congress and my predecessors handled resource conflicts by drawing enclosures: "We'll create a national park here," they said, "and we'll put a wildlife refuge over there." Simple enough, as far as protection goes. And outside those protected areas, the message was equally simplistic: "Y'all come and get it. Have at it." The nature and the pace of the resource extraction was not at issue; if you could find it, it was yours.

Download or read book Fingerprints of Climate Change written by G.-R. Walther and published by Springer Science & Business Media. This book was released on 2012-11-09 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years an increasing number of studies have been published reporting observations of adapted behaviour and shifting species ranges of plant and animal species due to recent climate warming. Are these `fingerprints' of climate change? An international conference was organised to bring together scientists from different continents with different expertise but sharing the same issue of climate change impact studies. Ecologists, zoologists, and botanists exchanged and discussed the findings from their individual field of research. The present book is an international collection of biological signs of recent climate warming, neither based only on computer models nor on prediction for the future, but mainly on actually occurring changes in the biosphere such as adapted behaviour or shifts in the ranges of species. `Fingerprints' of Climate Change presents ecological evidence that organisms are responding to recent global warming. The observed changes may foreshadow the types of impacts likely to become more frequent and widespread with continued warming.
Download or read book Conserving Migratory Pollinators and Nectar Corridors in Western North America written by Gary Paul Nabhan and published by University of Arizona Press. This book was released on 2023-03-07 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
