Keller and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Aerial survey data (December-March, 1991-1998) including survey tracklines and right whale locations were entered into a Geographic Information Systems (GIS) for comparing whale use of SST to availability based on search effort. Using Monte Carlo techniques, mean and standard deviation for SSTs and latitudes of whale-sightings were compared to sampling distributions derived from available SSTs and latitudes. From these data, it was concluded that the North Atlantic right whale uses SSTs and latitudes non-randomly. Broad-scale habitat selection for gopher tortoises was evaluated from the 2003 Land Cover/Land Use map (Florida Fish and Wildlife Conservation Commission). Based on land cover and ancillary data, potential gopher tortoise habitat was developed for northeast Florida.

Available in PDF, EPUB and Kindle. Book excerpt: Geographic Information Systems (GIS) provide a powerful tool for the investigation of species-habitat relationships and the development of wildlife management and conservation programs. However, the relative ease of data manipulation and analysis using GIS, associated landscape metrics packages, and sophisticated statistical tests may sometimes cause investigators to overlook important species-habitat functional relationships. Additionally, underlying assumptions of the study design or technology may have unrecognized consequences. This volume examines how initial researcher choices of image resolution, scale(s) of analysis, response and explanatory variables, and location and area of samples can influence analysis results, interpretation, predictive capability, and study-derived management prescriptions. Overall, most studies in this realm employ relatively low resolution imagery that allows neither identification nor accurate classification of habitat components. Additionally, the landscape metrics typically employed do not adequately quantify component spatial arrangement associated with species occupation. To address this latter issue, the authors introduce two novel landscape metrics that measure the functional size and location in the landscape of taxon-specific ‘solid’ and ‘edge’ habitat types. Keller and Smith conclude that investigators conducting GIS-based analyses of species-habitat relationships should more carefully 1) match the resolution of remotely sensed imagery to the scale of habitat functional relationships of the focal taxon, 2) identify attributes (explanatory variables) of habitat architecture, size, configuration, quality, and context that reflect the way the focal taxon uses the subset of the landscape it occupies, and 3) match the location and scale of habitat samples, whether GIS- or ground-based, to corresponding species’ detection locations and scales of habitat use.

This book was released on 2014-04-11 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inhaltsangabe:Introduction: Over 10% (1186 species) of the bird species in the world are threatened with extinction in the near future, almost all of them due to habitat change or loss by man. Likewise, 1130 mammals, 296 reptiles, 146 amphibians and 5611 plants have been identified as endangered species. The destruction of natural habitat is the major factor contributing to the global species extinction event. The increasing loss of biodiversity has centred on conducting inventories and monitoring species and habitats, especially in identifying areas of high species richness, threatened species and species of restricted or local distribution. In 1992 the UNCED-Conference in Rio de Janeiro pointed out the need for monitoring the environment, leading to the Convention on Biological Diversity and the Agenda 21. Article 7 of the Convention on Biological Diversity deals with identification and monitoring, which are to be undertaken with sampling and other techniques. New methodologies with a view to undertaking systematic sampling and evaluation of the components of biological diversity are to be developed. While the number of identified threatened species has increased dramatically, a huge gap in knowledge of ecosystems and their fauna and flora remains. Distribution, status and ecology of species are mostly unknown in many countries, as is the degree they are endangered. In view of the immense unknown ecosystems in the world, a great number of which are located in developing countries, conventional survey and mapping methods cannot deliver the necessary information in a timely and cost-effective fashion. Nature conservation will require large volumes of Remote Sensing (RS) data if the quality of planning is to improve. With RS technology, we may be able to make real progress in understanding why more species occur in some places than in others and in identifying the most critical places that must be protected to preserve the maximum number of species into the 22nd century and beyond. As current air photos are often not available, satellite images are the sole source of data for many regions of the world. Fortunately, computer technology has improved enormously in the last years, mainly processing time, storage requirements as well as programme features and possibilities. Concurrent declining costs of computer hardware have favoured the design of new techniques for special data processing and combining remotely sensed information with other extensive [...]
Download or read book Resource Selection by Animals written by B.F. Manly and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have written this book as a guide to the design and analysis of field studies of resource selection, concentrating primarily on statistical aspects of the comparison of the use and availability of resources of different types. Our intended audience is field ecologists in general and, in particular, wildlife and fisheries biologists who are attempting to measure the extent to which real animal populations are selective in their choice of food and habitat. As such, we have made no attempt to address those aspects of theoretical ecology that are concerned with how animals might choose their resources if they acted in an optimal manner. The book is based on the concept of a resource selection function (RSF), where this is a function of characteristics measured on resourceunits such that its value for a unit is proportional to the probability of that unit being used. We argue that this concept leads to a unified theory for the analysis and interpretation of data on resource selection and can replace many ad hoc statistical methods that have been used in the past.
Download or read book Spatial Analysis in Field Primatology written by Francine L. Dolins and published by Cambridge University Press. This book was released on 2021-02-18 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: From foraging patterns in a single tree to social interactions across a home range, how primates use space is a key question in the field of primate behavioral ecology. Drawing on the latest advances in spatial analysis tools, this book offers practical guidance on applying geographic information systems (GIS) to central questions in primatology. An initial methodological section discusses niche modelling, home range analysis and agent-based modelling, with a focus on remote data collection. Research-based chapters demonstrate how ecologists apply this technology to a suite of topics including: calculating the intensity of use of both range and travel routes, assessing the impacts of logging, mining and hunting, and informing conservation strategies.

This book was released on 2011-11 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Relatively little attention is currently given to the issue of biodiversity loss in savannah ecosystems and only a limited range of methods have been developed for the assessment and management of this issue. The aim of this study was to contribute to a better understanding of dry land woody species biodiversity and to test if woody species biodiversity assessment can be performed using remote sensing and geostatistics. The research was undertaken on an experimental site in the Serowe area, Botswana. A total of 169 sample plots were collected and analyzed. An importance value index (IVI), which is the summation of relative frequency, relative density and relative basal area, was used to select the dominant species of the area. The applicability of IKONOS imagery data and geostatistical techniques for savannah woody species biodiversity assessment were tested. A total of 33 woody species, which belong to 25 genera and 18 families, were identified. Two vegetation types were identified: dense savannah (SAD) and open savannah (SAO). The tree stems density was significantly higher (t-test, t=-4.39, d.f=167, p>0.001) in SAD than in SAO. According to the IVI criteria, the dominant species.

Available in PDF, EPUB and Kindle. Book excerpt: "This book covers selected topics on research methods in modern ecology, through the lens of 8 chapters, focusing on animal ecology, landcover assessment and habitat change, human perspectives and management, and research techniques, with examples taken from the Indian subcontinent. This area has emerged as one of the pivotal zones where cutting edge applications may be tested. Topics examined include the development and management of computer software techniques and the syntheses of these into pre-existing research methods, chemical analyses, including studies of animal dietary and foraging patterns, landcover, habitat and plant ecological change and even human/animal relations, and genetic studies. Remote sensing and geographical information systems are considered as cutting-edge research methods, at small, medium and large-scale levels, including more accurate positioning systems, more sensitive tracking systems, the removal of obstacles to clearer observation and species identification, such as darkness and poor lighting, dense vegetation and coarse image resolution and more comparative studies across different local contexts and global ecosystems. The topics cover geoinformatics applications to forest management in India, the paradigm shifts in this area, and the promotion and integration of sustainable forest management (SFM) and geoinformatics within the National Working Plan Code. Another case study is of Geoinformatics, Climate Change, Habitat Dynamics and a Case of Vultures in Central India, focusing on vulture ecology and related climatic variables, assessed with geoinformatics, Species Distribution Models (SDMs) and Global Circulation Models (GCMs). Other topics concern the use of tracking technologies including drones, the use of thermal and infrared drones in the study of large mammalian carnivores, the role of remote sensing and GIS in the assessment of natural resource development, clustering around the central concept of change detection, and the monitoring of agricultural development using socio-cultural parameters. This book presents these issues as some factors among the vast number of current ecological issues"--
Download or read book Using Remote Sensing and Geographic Information Systems to Define Conservation Priorities written by Clinton N. Jenkins and published by . This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation discusses several techniques of combining ecology and technology, specifically satellite images and geographic information systems, to define conservation priorities and answer conservation questions. They include single species approaches (chapters 2 and 3), global approaches (chapter 4), and regional approaches (chapters 5 and 6). Chapters 2 and 3 concern the Cape Sable Seaside Sparrow (Ammodramus mirabilis maritimus). This sparrow, and its habitat, is legally protected under the United States Endangered Species Act. Chapter 2 quantitatively demonstrates that poor water management is threatening the habitat of this sparrow and by consequence its survival. Chapter 3 describes formal testing of the habitat maps from chapter 2 and the ecological lessons learned from the test results. Chapter 4 is an analysis of the global 'weed patch', the area of the world that is favorable for invasive species. The results from this chapter should help define priority areas for combating invasive species. Chapters 5 and 6 discuss bird conservation in the Atlantic Forests of Brazil, specifically in the state of Rio de Janeiro. Chapter 5 approaches this from the forest level, focusing on forest fragment size and connectivity. Chapter 6 analyzes existing priority-setting methods in the Atlantic Forest, finds them deficient, and describes a new methodology to define bird conservation priorities.
Download or read book Spatial Database for GPS Wildlife Tracking Data written by Ferdinando Urbano and published by Springer Science & Business Media. This book was released on 2014-03-12 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book guides animal ecologists, biologists and wildlife and data managers through a step-by-step procedure to build their own advanced software platforms to manage and process wildlife tracking data. This unique, problem-solving-oriented guide focuses on how to extract the most from GPS animal tracking data, while preventing error propagation and optimizing analysis performance. Based on the open source PostgreSQL/PostGIS spatial database, the software platform will allow researchers and managers to integrate and harmonize GPS tracking data together with animal characteristics, environmental data sets, including remote sensing image time series, and other bio-logged data, such as acceleration data. Moreover, the book shows how the powerful R statistical environment can be integrated into the software platform, either connecting the database with R, or embedding the same tools in the database through the PostgreSQL extension Pl/R. The client/server architecture allows users to remotely connect a number of software applications that can be used as a database front end, including GIS software and WebGIS. Each chapter offers a real-world data management and processing problem that is discussed in its biological context; solutions are proposed and exemplified through ad hoc SQL code, progressively exploring the potential of spatial database functions applied to the respective wildlife tracking case. Finally, wildlife tracking management issues are discussed in the increasingly widespread framework of collaborative science and data sharing. GPS animal telemetry data from a real study, freely available online, are used to demonstrate the proposed examples. This book is also suitable for undergraduate and graduate students, if accompanied by the basics of databases.
