Download or read book Response of Desert Mule Deer to Habitat Alterations in the Lower Sonoran Desert written by and published by . This book was released on 2005 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: About 1,600,000 ha of desert mule deer range in Mexico are currently altered with vegetation clear-cutting and establishment of buffelgrass pastures. Consequently, the availability of resources as cover and forage from scrub vegetation has been reduced for mule deer. No previous research has been conducted to investigate how desert mule deer respond to those alterations. Therefore, the purpose of this research was to examine movements of mule deer, evaluate their home range sizes and determine habitat use, and analyze their diets in areas of central and western Sonora, Mexico. The approach involved the use of radiotelemetry techniques and GIS programs to calculate home range sizes, examine selection of vegetation associations, and identify the specific components of habitat that distinguished the characteristics of selected sites by desert mule deer. I used the microhistological technique to determine botanical components of desert mule deer diets, and compare diets of desert mule deer and cattle in habitat with buffelgrass pastures. Diet analyses included spatial and temporal comparisons of diversity and similarity indices. Sizes of home ranges were larger in the more arid environments of western Sonora (27.3 km2) than in central Sonora (14.5 km2). Desert mule deer used altered habitat differently than use areas without buffelgrass, however, there was no difference in the size of home ranges of mule deer from inside buffelgrass areas and the size of home ranges of deer in native scrub vegetation. Thermal cover, ground cover, and percent of gravel in the ground were the variables that distinguished locations selected by desert mule deer. Desert mule deer selected xeroriparian vegetation and sites closer to water sources. Water sources may have influenced mule deer to stay in buffelgrass areas despite the lack of cover and forage from shrubs and trees. For diets of mule deer, I identified 96 plant species, 69 of which have not previously been reported as forage for this herbivore. Desert mule deer and cattle shared 45 forage species from central Sonora. However, biological overlap of diets occurred only for spring. Results from these studies provide information to understand ecological relationships of desert mule deer on altered habitats.

This book was released on 1996-01-01 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Science and Ecosystem Management in the National Parks presents twelve case studies of long-term research conducted in and around national parks that address major natural resource issues. These cases demonstrate how the use of longer time scales strongly influences our understanding of ecosystems and how interpretations of short-term patterns in nature often change when viewed in the context of long-term data sets. Most important, they show conclusively that scientific research significantly reduces uncertainty and improves resource management decisions. Chosen by scientists and senior park managers, the cases offer a broad range of topics, including air quality at the Grand Canyon; interaction between moose and wolf populations on Isle Royale; control of exotic species in Hawaiian parks; simulation of natural fire in the parks of the Sierra Nevada; and the impact of urban expansion on Saguaro National Monument. Because national parks are increasingly beset with conflicting views of their management, the need for knowledge of park ecosystems becomes even more critical - not only for the parks themselves, but for what they can tell us about survival in the rest of our world. This book demonstrates to policymakers and managers that decisions based on knowledge of ecosystems are more enduring and cost effective than decisions derived from uninformed consensus. It also provides scientists with models for designing research to meet threats to our most precious natural resources. "If we can learn to save the parks", observe Halvorson and Davis, "perhaps we can learn to save the world".

Download or read book And Then There Were None written by Paul R. Krausman and published by University of New Mexico Press. This book was released on 2017-04-01 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Once plentiful in the mountains of southern Arizona, by the 1990s desert bighorn sheep were wiped out in the Pusch Ridge Wilderness of the Santa Catalina Mountains as a result of habitat loss and alteration. This book uses their history and population decline as a case study in human alteration of wildlife habitat. When human encroachment had driven the herd to extinction, wildlife managers launched a major and controversial effort to reestablish this population. For more than forty years Paul R. Krausman directed studies of the Pusch Wilderness population of these iconic animals, located in the mountainous outskirts of Tucson. The story he tells here reveals the complex relationships between politics and biology in wildlife conservation. His account of the evolution of wildlife conservation practices includes discussions of techniques and of human attitudes toward predators, fire, and their management.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: I studied the behaviors, movement dynamics, habitat relationships, and population characteristics of Rocky Mountain mule deer (Odocoileus hemionus) using urban and rural winter ranges in Cache Valley, Utah , from January 1994 to February 1998. There were 2 goals to my research endeavors. The first was to assess how and why the behaviors and demographic characteristics of urban deer differed from those of rural deer. The second was to assess the scale-dependent responses to habitat and the scale-dependent patterns of habitat use by deer living in each area. To accomplish the first goal, I compared the prevalence of migration, the spatial and temporal patterns of migration, and the spatial patterns of home range use between urban and rural deer. I also compared deer reproduction and population density in each area. I then explain how behavioral and demographic dissimilarities between urban and rural deer may have corresponded to differences in their net energetic gains (NEG) on seasonal ranges. These explanations, when combined graphically, generated a time-specific hypothesis of lower NEG by urban deer on a year-round basis. To accomplish the second goal, I developed new methodologies for analyzing animal movement pathways (which represent signatures of how animals respond to habitat), and animal patterns of habitat use . These methodologies explicitly incorporated the effects of spatial scale by employing fractal geometry and information theory. The results of these analyses showed that urban and rural deer responded to their habitats in similar ways at coarse resolutions of analysis (100-600 m), but differently at fine resolutions of analysis ( 4-60 m). I argue that similarities in habitat response at coarse resolutions reflected a common movement process that allowed deer maximize use of their home ranges while minimizing energetic expenditures. With respect to patterns of habitat use, urban deer concentrated in areas with concealment vegetation , which was highly fragmented across all resolutions of analysis. Rural deer, on the other hand, dispersed throughout areas containing shrubby vegetation at fine resolutions, and south-facing slopes at coarse resolutions. Interpretation of these results is discussed in detail.

Available in PDF, EPUB and Kindle. Book excerpt: “Wetland Habitats of North America is essential reading for everyone who studies, manages, or visits North American wetlands. It fills an important void in the wetland literature, providing accessible and succinct descriptions of all of the continent’s major wetland types.” Arnold van der Valk, Iowa State University “Batzer and Baldwin have compiled the most comprehensive compendium of North American wetland habitats and their ecology that is presently available—a must for wetland scientists and managers.” Irving A. Mendelssohn, Louisiana State University "If you want to gain a broad understanding of the ecology of North America’s diverse wetlands, Wetland Habitats of North America is the book for you. Darold Batzer and Andrew Baldwin have assembled an impressive group of regional wetland scientists who have produced a virtual encyclopedia to the continent’s wetlands. Reading the book is like a road trip across the Americas with guided tours of major wetland types by local experts. Your first stop will be to coastal wetlands with eight chapters covering tidal wetlands along the Atlantic, Gulf, and Pacific coasts. Then you’ll travel inland where you can visit any or all of 18 types ranging from bottomland swamps of the Southeast to pothole marshes of the Northern Prairies to montane wetlands of the Rockies to tropical swamps of Central America and desert springs wetlands. All in one book—I’m impressed! Every wetlander should add this book to her or his swampland library. Ralph Tiner, University of Massachusetts–Amherst
