Book Synopsis Evaluating Effects of Ecological Change on Important Sport Fishes in Oneida Lake, New York by : Brian James Irwin
Download or read book Evaluating Effects of Ecological Change on Important Sport Fishes in Oneida Lake, New York written by Brian James Irwin and published by . This book was released on 2006 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquatic ecosystems provide numerous resources to diverse user groups. As a result, these systems are often targets of planned management actions but are also sensitive to uncontrolled biological invasions. Oneida Lake has a rich history of ecological study across multiple trophic levels and has experienced notable perturbations to its food web during the past half-century. To evaluate large-scale ecological changes, I used multiple approaches to examine dynamics in several longterm data series. In Chapter 1, I quantified age-0 yellow perch density at four early life stages and calculated mortality and growth rates. At all stages, densities have declined over time. Mortality rates from egg to 18mm showed no time trend, increased for 18mm - 1 Aug., and decreased from 1 Aug. - 15 Oct. Depensatory mortality, prevalent in the 1960s to early 1970s, was not seen in recent years. Growth has increased, was density dependent, and was significantly correlated with increased Secchi depth. The combined effect has been a decline in abundance and an increase in individual size by the end of the first year. In Chapter 2, I combined three long-term data sets for walleye to simultaneously estimate mortality, catchability in gillnets and trawls, and density using a non-linear minimization routine. A multi-mortality model with two time periods suggested decreased fishing mortality but increased sub-adult mortality during recent years when more restrictive size limits were in place and double-crested cormorants were abundant. In Chapter 3, I used gillnet and bottom trawl catches to identify changes in fish abundance after zebra mussel colonization. Based on a priori expectations, I evaluated changes between pre- and post-zebra mussel periods and compared observed values with projections from 30-year population trajectories. Between periods, gillnet catches of Pelagic fishes declined while catches of Littoral and Benthic fishes increased. Population trajectories indicated declining percids; however, gillnet catches of smallmouth bass and pumpkinseed sunfish remained high throughout much of the zebra mussel period. Changing ecological conditions (increased water clarity, temperature, and macrophytes; altered nutrient pathways; and variable top predators) appear to favor a fish community shift away from percids and towards centrarchids.

Download or read book Wildlife and Recreationists written by Richard L. Knight and published by Island Press. This book was released on 2013-04-22 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wildlife and Recreationists defines and clarifies the issues surrounding the conflict between outdoor recreation and the health and well-being of wildlife and ecosystems.

More important, it addresses both research needs and management options to minimize conflicts.
Book Synopsis Thermal Imaging Techniques to Survey and Monitor Animals in the Wild by : Kirk J Havens
Download or read book Thermal Imaging Techniques to Survey and Monitor Animals in the Wild written by Kirk J Havens and published by Academic Press. This book was released on 2015-09-22 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermal Imaging Techniques to Survey and Monitor Animals in the Wild: A Methodology provides a manual for anyone interested in understanding thermal imaging and its usefulness in solving a wide range of problems regarding the observation of wildlife. In the last decade, the cost of thermal imaging technology has significantly decreased, making the equipment more widely available. This book offers an overview of thermal physics and the thermal imager, along with a methodology to optimize the window of opportunity so that wildlife can be observed and studied in their natural habitat. Users will find the knowledge and tools to formulate a sound survey design, with detailed sections on the theory and performance characteristics of thermal imaging cameras utilizing cooled quantum detectors as the sensitive element and additional information on the uncooled micro bolometric imagers which have been introduced into the camera market in past decades. The methodology presented is logical and simple, yet it presents a detailed understanding of the topic and how it applies to the critically interlinked disciplines of biology, physics, micrometeorology, and animal physiology. - Covers the technical aspects of thermal imaging allowing readers to design better experiments - Provides a clear description of the properties of thermal imaging - Includes approaches to consider before integrating thermal cameras into a field

Book Synopsis Habitat Suitability and Distribution Models by : Antoine Guisan
Download or read book Habitat Suitability and Distribution Models written by Antoine Guisan and published by Cambridge University Press. This book was released on 2017-09-14 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the key stages of niche-based habitat suitability model building, evaluation and prediction required for understanding and predicting future patterns of species and biodiversity. Beginning with the main theory behind ecological niches and species distributions, the book proceeds through all major steps of model building, from conceptualization and model training to model evaluation and spatio-temporal predictions. Extensive examples using R support graduate students and researchers in quantifying ecological niches and predicting species distributions with their own data, and help to address key environmental and conservation problems. Reflecting this highly active field of research, the book incorporates the latest developments from informatics and statistics, as well as using data from remote sources such as satellite imagery. A website at www.unil.ch/hsdm contains the codes and supporting material required to run the examples and teach courses.

Book Synopsis Wildlife Ecotoxicology by : John E. Elliott
Download or read book Wildlife Ecotoxicology written by John E. Elliott and published by Springer Science & Business Media. This book was released on 2011-08-27 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many books have now been published in the broad field of environmental toxicology. However, to date, none of have presented the often fascinating stories of the wildlife science, and the steps along the way from discovery of problems caused by environmental pollutants to the regulatory and non-regulatory efforts to address the problems. This book provides case by case examinations of how toxic chemical effects on wildlife have brought about policy and regulatory decisions, and positive changes in environmental conditions. Wild animal stories, whether they are about the disappearance of charismatic top predators, or of grossly deformed embryos or frogs, provide powerful symbols that can and have captured the public's imagination and have resulted in increased awareness by decision makers. It is the intent of this book to present factual and balanced overviews and summaries of the science and the subsequent regulatory processes that followed to effect change (or not). We cover a variety of chemicals and topics beginning with an update of the classic California coastal DDT story of eggshell thinning and avian reproduction to more recent cases, such as the veterinarian pharmaceutical that has brought three species of Asian vultures to the brink of extinction. Researchers, regulators, educators, NGOs and the general public will find valuable insights into the processes and mechanisms involved both in environmental scientific investigation and in efforts to effect positive change.
