This book was released on 2020 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Habitat fragmentation, including damming rivers, is a major threat to species conservation in urban areas causing reduced dispersal and biodiversity. Dam removal is typically beneficial to many species because dams restrict the movement of many organisms. However, the dam removal may negatively impact some species. The purpose of our study was to assess the potential effects that the removal of the Peninsular Paper Dam (Huron River, Ypsilanti) may have on painted turtles (Chrysemys picta) by monitoring their habitat use prior to dam removal. Chrysemys picta is a native species abundant in lentic systems (ponds and lakes) with muddy substrates, conditions found in the currently impounded area. Following dam removal, much of this habitat is likely to change dramatically to a rocky, fast-flowing river system that is less conducive to supporting Chrysemys picta. We tracked eight female turtles daily over the summer of 2019 using radio-telemetry. Using GPS location data and predicted river flow following dam removal, we found most of aquatic habitat currently used by C. picta, including overwintering sites, will disappear. Our results suggest that the future river may not be optimal C. picta habitat following the dam removal, and therefore this species should be actively managed throughout the dam removal process.
Book Synopsis Movement, Habitat Selection, and Resource Use by Western Painted Turtles (Chrysemys Picta Bellii) in an Urban Environment Near Their Northern Range Limit by : Kelsey Allison Marchand
Download or read book Movement, Habitat Selection, and Resource Use by Western Painted Turtles (Chrysemys Picta Bellii) in an Urban Environment Near Their Northern Range Limit written by Kelsey Allison Marchand and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding resource use is necessary to properly manage and conserve habitats for long-lived species, especially for populations residing urban settings. I studied habitat selection, space use, and isotopic resource use of an urban population of western painted turtles (Chrysemys picta bellii) residing in Wascana Creek in Regina, Saskatchewan from May 2015 to April 2017. Using radio-telemetry to track movements, I determined habitat selection at multiple spatial (Johnson's second and third order habitat selection) and temporal scales (active season; encompassing emergence, nesting, and post-nesting) using compositional analysis. I found that turtles selected for shoreline habitat over urban/parkland and open water (second order). The characteristics of the selected shoreline (third order) varied between habitat areas; however, they did not substantially differ across the active season. Within creek habitat, turtles chose shoreline habitat randomly. Within marsh habitat, turtles selected for particular shoreline features, preferring treed shoreline across all three periods of the active season. Across the active season, both male and female turtles moved significantly more during emergence than during nesting and post-nesting periods and movements were larger in marsh habitat than creek habitat. Suitable overwintering locations were limited within the study area, and were warmer and deeper than those randomly available, likely ensuring that their overwintering locations did not freeze. There was no significant difference in the dissolved oxygen level between used and available overwintering sites. I measured stable isotopes of carbon and nitrogen from nail samples to examine isotopic resource use within and among the populations in two habitats (marsh and creek). Isotopic niche size varied across the population as a result of variation in body size, sex, and location. Isotopic niches overlapped between 26-77%, with the least overlap between males and females. This indicates that although western painted turtles are generalist omnivores, there is indication of distinct isotopic resource use by subgroups. By comparing the isotopic values found in the turtles to those found in prey, I found that all turtles consumed low proportions of a wide variety of potential prey items, but there were differences among subgroups. Female and sub-adult turtles in the marsh consumed a higher proportion of crayfish and males consume a higher proportion of amphipods, whereas turtles in the creek consumed a higher proportion of chironomid larvae in comparison to the other available prey items. Turtles in this urban environment require aquatic systems with high productivity and diversity, vegetated shorelines to provide buffers from disturbance as well as provide suitable basking areas (i.e. banks with overhanging trees), and protected overwintering habitat that is at least 2 m deep. My findings indicate that turtles take advantage of a wide range of resources; however, there are particular requirements that are necessary to ensure their survival and long-term persistence in this environment.

Book Synopsis Wetland Techniques by : James T. Anderson
Download or read book Wetland Techniques written by James T. Anderson and published by Springer Science & Business Media. This book was released on 2013-10-10 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wetlands serve many important functions and provide numerous ecological services such as clean water, wildlife habitat, nutrient reduction, and flood control. Wetland science is a relatively young discipline but is a rapidly growing field due to an enhanced understanding of the importance of wetlands and the numerous laws and policies that have been developed to protect these areas. This growth is demonstrated by the creation and growth of the Society of Wetland Scientists which was formed in 1980 and now has a membership of 3,500 people. It is also illustrated by the existence of 2 journals (Wetlands and Wetlands Ecology and Management) devoted entirely to wetlands. To date there has been no practical, comprehensive techniques book centered on wetlands, and written for wetland researchers, students, and managers. This techniques book aims to fill that gap. It is designed to provide an overview of the various methods that have been used or developed by researchers and practitioners to study, monitor, manage, or create wetlands. Including many methods usually found only in the peer-reviewed or gray literature, this 3-volume set fills a major niche for all professionals dealing with wetlands.
Book Synopsis The Estimation of Animal Abundance and Related Parameters by : George Arthur Frederick Seber
Download or read book The Estimation of Animal Abundance and Related Parameters written by George Arthur Frederick Seber and published by . This book was released on 2002 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1982, this reprint of the second edition of The Estimation of Animal Abundance and Related Parameters has been described as the "bible" of the field. Censuses of living populations are required for many purposes in wildlife management, fisheries and pest control and they are essential in policy making for the protection of the environment. In this book Professor Seber, one of the leading experts in the field, explains in detail the methods that have been developed by ecologists for estimating animal numbers and related parameters such as mortality and birth rates. He insists on the importance of experimental design and describes a great variety of statistical techniques that are required in analyzing the data obtained. These designs and techniques are classified for easy reference according to the particular types of problems encountered by the field worker and the kind of information that is available. The assumptions underlying practical methods in current use are fully examined, together with procedures for testing their validity. Each method is demonstrated by at least one worked example; in all there are over 90 such examples, mostly using data obtained from natural or free-ranging populations around the world. Ecologists will find this book - the first full-length treatment of its subject - a sound statistical assessment of methods which in the past were frequently developed on an intuitive basis; while applied mathematicians will benefit no less from a study of the interaction between mathematics and biology in this important branch of statistics. Field workers will be stimulated and helped by the real-life examples and the practical nature of the work. "George Seber's book became an instant classic following its publication in 1973. It dealt comprehensively with previously published research on methods for estimating abundance and demographic parameters of animal populations. Professor Seber provided detailed reviews of methods that were originally published with adequate statistical development, and he provided derivations and development for intuitive estimators that had been initially presented by ecologists. The second edition of the book was published in 1982 and included substantive additional coverage of "new" developments that had occurred since 1973. The 1982 book has become a citation classic and can be found on the bookshelf of every serious animal population ecologist and every biostatistician dealing with animal population data. For the 20 years since its publication, it has remained the only book of its kind. Many important methodological developments have occurred in animal estimation problems since 1982, but virtually all such methods represent extensions of the initial methods described by Seber (1982). Several excellent monographs and books have been written over the last 2 decades that deal in detail with particular subsets of the material in Seber (1982). What is remarkable is that these recent contributions have not superseded Seber's book, but are best viewed as supplements to his original comprehensive treatment. Thus, Seber's (1982) book can still be found on the bookshelf of every serious animal population ecologist and biostatistician. Now, in 2002, it is surrounded on the bookshelf by a handful of related books and monographs, but it has not lost its relevance or importance and remains the most detailed, comprehensive treatment of methods to estimate animal abundance and related parameters." Jim Nichols, Patuxent Wildlife Research Center, U.S. Geological Survey, Laurel, MD Professor Seber, Professor Emeritus at the University of Auckland, is regarded as the world's foremost authority on statistical methods for estimating the size of animal populations. His early work on capture-recapture methods was groundbreaking and the Jolly-Seber method still forms the basis of most modern work, more than 30 years after his first paper on the method in 1962.
Book Synopsis Beavers: Boreal Ecosystem Engineers by : Carol A. Johnston
Download or read book Beavers: Boreal Ecosystem Engineers written by Carol A. Johnston and published by Springer. This book was released on 2017-08-28 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bridging the fields of ecosystem science and landscape ecology, this book integrates Dr. Carol Johnston's research on beaver ecosystem alteration at Voyageurs National Park. The findings about the vegetation, soils, and chemistry of beaver impoundments synthesized in the text provide a cohesive reference useful to wetland scientists, ecosystems and landscape ecologysts, wildlife managers, and students. The beaver, Castor canadensis, is an ecosystem engineer unequaled in its capacity to alter landscapes through browsing and dam building, whose population recovery has re-established environmental conditions that probably existed for millenia prior to its near extirpation by trapping in the 1800s and 1900s. Beavers continue to regain much of their natural range throughout North America, changing stream and forest ecosystems in ways that may be lauded or vilified. Interest in beavers by ecologists remains keen as new evidence emerges about the ecological, hydrological, and biogeochemical effects of beaver browsing and construction. There is a critical need for ecologists and land managers to understand the potential magnitude, persistence, and ecosystem services of beaver landscape transformation. The 88-year record of beaver landscape occupation and alteration documented by Dr. Carol Johnston and colleagues from aerial photography and field work provides a unique resource toward understanding the ecosystem effects and sustainability of beaver activity.

Book Synopsis Southwestern Desert Resources by : William L. Halvorson
Download or read book Southwestern Desert Resources written by William L. Halvorson and published by University of Arizona Press. This book was released on 2023-01-17 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: The southwestern deserts stretch from southeastern California to west Texas and then south to central Mexico. The landscape of this region is known as basin and range topography featuring to “sky islands” of forest rising from the desert lowlands which creates a uniquely diverse ecology. The region is further complicated by an international border, where governments have caused difficulties for many animal populations. This book puts a spotlight on individual research projects which are specific examples of work being done in the area and when they are all brought together, to shed a general light of understanding the biological and cultural resources of this vast region so that those same resources can be managed as effectively and efficiently as possible. The intent is to show that collaborative efforts among federal, state agency, university, and private sector researchers working with land managers, provides better science and better management than when scientists and land managers work independently.

Book Synopsis Health and Welfare of Captive Reptiles by : Clifford Warwick
Download or read book Health and Welfare of Captive Reptiles written by Clifford Warwick and published by Springer Nature. This book was released on 2023-01-24 with total page 637 pages. Available in PDF, EPUB and Kindle. Book excerpt: This extensively revised and expanded new edition offers concepts, principles and applied information that relates to the wellbeing of reptiles. As a manual on health and welfare in a similar vein to volumes addressing the sciences of anatomy, behaviour or psychology, this book thoroughly examines the biology of reptile welfare and is about meeting biological needs. The editors, acknowledged experts in their own right, have once again drawn together an extremely impressive international group of contributors. Positive and negative implications of general husbandry and research programs are discussed. In addition to greatly revised original content are nine new chapters offering readers novel insight into: • sensory systems • social behaviour • brain and cognition • controlled deprivation and enrichment • effects of captivity-imposed noise and light disturbance on welfare • spatial and thermal factors• evidential thresholds for species suitability in captivity • record keeping as an aid to captive care • arbitrary husbandry practices and misconceptions The authors have adopted a user-friendly writing style to accommodate a broad readership. Although primarily aimed at academic professionals, this comprehensive volume is fundamentally a biology book that will also inform all involved in captive reptile husbandry. Among others, zoo personnel, herpetologists, veterinarians, lab animal scientists, and expert readers in animal welfare and behavioural studies will benefit from this updated work.

Book Synopsis Recovering Australian Threatened Species by : Stephen Garnett
Download or read book Recovering Australian Threatened Species written by Stephen Garnett and published by CSIRO PUBLISHING. This book was released on 2018-03 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: Australia’s nature is exceptional, wonderful and important. But much has been lost, and the ongoing existence of many species now hangs by a thread. Against a relentless tide of threats to our biodiversity, many Australians, and government and non-government agencies, have devoted themselves to the challenge of conserving and recovering plant and animal species that now need our help to survive. This dedication has been rewarded with some outstanding and inspiring successes: of extinctions averted, of populations increasing, of communities actively involved in recovery efforts. Recovering Australian Threatened Species showcases successful conservation stories and identifies approaches and implementation methods that have been most effective in recovering threatened species. These diverse accounts – dealing with threatened plants, invertebrates, fish, reptiles, birds and mammals – show that the conservation of threatened species is achievable: that it can be done and should be done. They collectively serve to inform, guide and inspire other conservation efforts. This is a book of hope and inspiration. It shows that with dedication, knowledge and support, we can retain and restore our marvellous natural heritage, and gift to our descendants a world that is as diverse, healthy and beautiful as that which we have inherited.
