This book was released on 2009 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Central Sierra Nevada great gray owls are facultative, elevational, winter migrants. Access to winter habitat is important to their ecology. Winter observations and remotely sensed habitat variables informed a predictive model of the environmental requirements and geographic distribution of this owl population. Using the modeled distribution map we analyzed habitat variables, ownership, development footprint, and projected development across 20% probability classes. The high probability class (80-100%) was only 0.2% of the total study area. High-probability areas were characterized by Sierran Yellow Pine forest surrounding relatively small, flat areas of grassland, wet meadow, and riparian habitats, within the mid-elevation range. Winter great gray owls preferred undeveloped, wildland areas. The major landowners of the high probability class were United States Forest Service (23%), National Park Service (43%), private landowners (32%), and miscellaneous agencies (2%). Less than 1% of preferred habitat on agency-owned lands was developed, while 38% of preferred habitat on private lands was developed past a rural density. Similarly, projected development involved only private lands, with 44% and 60% of high- and medium-to-high (40-100%) suitability areas respectively developed beyond rural by the year 2040. Our findings indicate that there is a strong overlap in winter areas preferred by great gray owls in the central Sierra Nevada and areas that are currently and projected to be developed in the near future. To ensure population viability of the central Sierra Nevada great gray owl, conservation efforts should prioritize habitat preservation in areas of private ownership that overlap with preferred great gray owl winter habitat.

Book Synopsis Variation in Habitat Selection, Seasonal Movements, and Reproductive Output of a Facultative Migrant, the Great Gray Owl by : Katherine Blair Gura
Download or read book Variation in Habitat Selection, Seasonal Movements, and Reproductive Output of a Facultative Migrant, the Great Gray Owl written by Katherine Blair Gura and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Identifying key habitat, responses to environmental change, and determinants of fitness are primary goals in ecology. I investigated mechanisms underlying variation in resource selection, movement behavior, and reproductive performance of Great Gray Owls in the Greater Yellowstone Ecosystem in Wyoming and Idaho, USA. In Chapter 1, I quantified resource selection of adult owls (n = 42) and observed different patterns of selection depending on spatiotemporal scale, including between the breeding versus winter seasons. In Chapter 2, I evaluated whether breeding-season resource selection by adult male owls (n = 19) varied across diurnal periods, to improve understanding of foraging and nocturnal habitat. Owls avoided herbaceous wetlands during daytime but strongly selected them at dawn, dusk, and night. They also chose nighttime microhabitat that enabled foraging, such as presence of primary prey and open understories. In Chapter 3, I evaluated whether snow conditions influenced proximate habitat choices and/or migratory movements by Great Gray Owls. Owls proximately avoided deeper snow and more severe wind crusts, whereas probability of migration increased with more severe and persistent ice crusts. Owls appeared to be behaviorally plastic, adopting different strategies depending on the spatial scale and duration of limiting conditions. In Chapter 4, I investigated whether breeding-season prey abundance or prior winter snow conditions influenced reproductive output. Snow conditions during the preceding winter carried over to determine subsequent breeding. Such detailed assessments of factors across scales and contexts contribute to a more thorough understanding of resource requirements, susceptibility to environmental change, and population dynamics.
Book Synopsis Ecological Identity by : Mitchell Thomashow
Download or read book Ecological Identity written by Mitchell Thomashow and published by MIT Press. This book was released on 1996-07-25 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Through theoretical discussion as well as hands-on participatory learning approaches, Thomashow provides concerned citizens, teachers, and students with the tools needed to become reflective environmentalists. Mitchell Thomashow, a preeminent educator, shows how environmental studies can be taught from different perspective, one that is deeply informed by personal reflection. Through theoretical discussion as well as hands-on participatory learning approaches, Thomashow provides concerned citizens, teachers, and students with the tools needed to become reflective environmentalists. What do I know about the place where I live? Where do things come from? How do I connect to the earth? What is my purpose as a human being? These are the questions that Thomashow identifies as being at the heart of environmental education. Developing a profound sense of oneself in relationship to natural and social ecosystems is necessary grounding for the difficult work of environmental advocacy. In this book he provides a clear and accessible guide to the learning experiences that accompany the construction of an "ecological identity": using the direct experience of nature as a framework for personal decisions, professional choices, political action, and spiritual inquiry. Ecological Identity covers the different types of environmental thought and activism (using John Muir, Henry David Thoreau, and Rachel Carson as environmental archetypes, but branching out into ecofeminism and bioregionalism), issues of personal property and consumption, political identity and citizenship, and integrating ecological identity work into environmental studies programs. Each chapter has accompanying learning activities such as the Sense of Place Map, a Community Network Map, and the Political Genogram, most of which can be carried out on an individual basis. Although people from diverse backgrounds become environmental activists and enroll in environmental studies programs, they are rarely encouraged to examine their own history, motivations, and aspirations. Thomashow's approach is to reveal the depth of personal experience that underlies contemporary environmentalism and to explore, interpret, and nurture the learning spaces made possible when people are moved to contemplate their experience of nature.
Book Synopsis The End of Nature by : Bill McKibben
Download or read book The End of Nature written by Bill McKibben and published by Random House. This book was released on 2014-09-03 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reissued on the tenth anniversary of its publication, this classic work on our environmental crisis features a new introduction by the author, reviewing both the progress and ground lost in the fight to save the earth. This impassioned plea for radical and life-renewing change is today still considered a groundbreaking work in environmental studies. McKibben's argument that the survival of the globe is dependent on a fundamental, philosophical shift in the way we relate to nature is more relevant than ever. McKibben writes of our earth's environmental cataclysm, addressing such core issues as the greenhouse effect, acid rain, and the depletion of the ozone layer. His new introduction addresses some of the latest environmental issues that have risen during the 1990s. The book also includes an invaluable new appendix of facts and figures that surveys the progress of the environmental movement. More than simply a handbook for survival or a doomsday catalog of scientific prediction, this classic, soulful lament on Nature is required reading for nature enthusiasts, activists, and concerned citizens alike.

Download or read book The Biology of Camel-Spiders written by Fred Punzo and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: My initial interest in the Solifugae (camel-spiders) stems from an incident that occurred in the summer of 1986. I was studying the behavioral ecology of spider wasps of the genus Pepsis and their interactions with their large theraphosid (tarantula) spider hosts, in the Chihuahuan Desert near Big Bend National Park, Texas. I was monitoring a particular tarantula burrow one night when I noticed the resident female crawl up into the burrow entrance. Hoping to take some photographs of prey capture, I placed a cricket near the entrance and waited for the spider to pounce. Suddenly, out of the comer of my eye appeared a large, rapidly moving yellowish form which siezed the cricket and quickly ran off with it until it disappeared beneath a nearby mesquite bush. So suddenly and quickly had the sequence of events occurred, that I found myself momentarily startled. With the aid of a headlamp I soon located the intruder, a solifuge, who was already busy at work macerating the insect with its large chelicerae (jaws). When I attempted to nudge it with the edge of my forceps, it quickly moved to another location beneath the bush. When I repeated this maneuver, the solifuge dropped the cricket and lunged at the forceps, gripping them tightly in its jaws, refusing to release them until they were forcefully pulled away.
Book Synopsis Mammals and Birds as Bioindicators of Trace Element Contaminations in Terrestrial Environments by : Elżbieta Kalisińska
Download or read book Mammals and Birds as Bioindicators of Trace Element Contaminations in Terrestrial Environments written by Elżbieta Kalisińska and published by Springer. This book was released on 2019-03-01 with total page 708 pages. Available in PDF, EPUB and Kindle. Book excerpt: The population explosion that began in the 1960s has been accompanied by a decrease in the quality of the natural environment, e.g. pollution of the air, water and soil with essential and toxic trace elements. Numerous poisonings of people and animals with highly toxic anthropogenic Hg and Cd in the 20th century prompted the creation of the abiotic environment, mainly in developed countries. However, the system is insufficient for long-term exposure to low concentrations of various substances that are mainly ingested through food and water. This problem could be addressed by the monitoring of sentinels – organisms that accumulate trace elements and as such reflect the rate and degree of environmental pollution. Usually these are long-lived vertebrates – herbivorous, omnivorous and carnivorous birds and mammals, especially game species. This book describes the responses of the sentinels most commonly used in ecotoxicological studies to 17 trace elements.
