This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Brook Trout is a socially, economically and ecologically important species throughout its native range in the eastern U.S. that is expected to be negatively affected by climate and land use change. In this dissertation, I use publicly available data to identify the potential effects of projected climate and land use change on river water temperature and Brook Trout populations in individual stream reaches throughout the eastern U.S. In Chapter 1, I quantitatively assessed the representativeness of stream flow and water temperature data from U. S. Geological Survey (USGS) gages throughout subregions of the conterminous United States, including the eastern U.S. In Chapter 2, I developed a model to predict river water temperatures under current conditions and future scenarios of climate and land use change. The final model included air temperature, landform attributes and forested land cover, and predicted mean daily water temperatures with good accuracy (root mean squared error ~ 1.9 °C) for training and validation datasets. In Chapter 3, I predicted Brook Trout occurrence probability based on water temperature predictions and selected landscape characteristics using a hierarchical logistic regression model that performed well at both training and validation datasets (area under the receiver operating curve ~ 0.78). In Chapter 4, I identified potential changes in thermal habitat and Brook Trout occurrence probability resulting from projected climate and land use change. The timing, magnitude and location of predicted changes in maximum 30 day mean river water temperature varied greatly among three downscaled climate models, with average increases ranging from 1.21 to 2.55 °C by 2087. As a result of warming, between 56,440 (42.7%) and 109,237 (82.6%) of potential Brook Trout habitat was predicted to be lost. Land use change was predicted to result in localized increases in river water temperature and losses of 4.5% of potential Brook Trout habitat. Given the magnitude of predicted losses, conservation actions will likely be more successful in the long term if the potential changes resulting from climate and land use change are incorporated into the planning process.

Book excerpt: The eastern brook trout is the only trout (charr) species native to the eastern U.S., which contains approximately 25% of the entire native range of the brook trout and 70% of the U.S. range. Stream temperature is a fundamental limiting factor in the distribution and production of brook trout and their range is bounded to the south by a mean July air temperature of 21Ã'ÂoC. Average air temperature in the U.S. has risen by 0.6Ã'ÂoC over the last century and may increase by another 6Ã'ÂoC over the next 100 years. Climate warming may threaten the long-term survival of the brook trout populations in the southern Appalachian Mountains. Using projected future climate scenarios and land use/land cover classes, we developed ordinal and binary logistic regression models to characterize current habitat suitability of brook trout, determine future suitable habitat and prioritize subwatersheds for brook trout conservation. Explanatory variables held in common in every model were the baseline variables (either forest or agriculture), the respective baseline variable with temperature as an interaction term and wetlands. This analysis further supports temperature as a major driver in the distribution of brook trout. Projected future suitable habitat was shown to be moving further north over time. This analysis resulted in map outputs illustrating areas of greatest brook trout population subwatershed status changes and indicates potential areas of concern for brook trout survival due to projected future climate scenarios. These results can aid in prioritizing subwatersheds for brook trout conservation and restoration.

Available in PDF, EPUB and Kindle. Book excerpt: The brook trout (Salvelinus fontinalis) is an iconic species among fly anglers and cold-water conservationists in eastern North America. This fish registers as a powerful symbol for its beauty and its imagery in art and literature. Its presence also tells us a great deal about the health of the larger environment. When an angler has a brook trout in hand, there is confidence that the water is close to pristine. Besides being an important indicator species, the brook trout, with its gold and reddish markings and its camouflaged green and black back, is one of the most beautiful freshwater fish in North America. And beyond the beauty of the fish itself, the environment in which it is found is also part of its past and present appeal. To fish for brook trout is often to fish in the last remote and rugged landscapes in the East, “fishscapes” that have not been polluted by stocking trucks that dump nonnative brown and rainbow trout in most of the East’s accessible cold waterways. Searching for Home Waters is part science, part environmental history, and part personal journey of the author, Michael K. Steinberg, and those he interviewed during his travels. The work takes a broad perspective that examines the status of brook trout in the eastern United States, employing a “landscape” approach. In other words, brook trout do not exist in a vacuum; they are impacted by logging, agriculture, fishing policies, suburban development, mining, air pollution, and climate change. Thus, while the book focuses specifically on the status and management of the brook trout—from Georgia to Labrador—it also tells the larger story of the status of the eastern environment. As a “pilgrimage,” this book is also a journey of the heart and contains Steinberg’s personal reflections on his relationship with the brook trout and its geography.

Download or read book Effects of Climate and Terrestrially Derived Organic Carbon on Brook Trout Growth in the Eastern Sierra written by Cindy Hang Tran and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anthropogenic climate change is expected to continue increasing temperatures globally as well as alter the nutrient composition of many ecosystems. Higher air temperatures have been causing lakes to warm, and dissolved organic carbon (DOC) concentrations are rising in many freshwater systems due to increased input of terrestrial organic matter, a phenomenon known as "browning." The combined effects of warming and browning on fish populations is unclear. I investigated the effects of warming and browning on brook trout (Salvelinus fontinalis), an ecologically and economically important species in California's Eastern Sierra. A previous study found antagonistic effects of temperature and DOC on fish growth rates, with higher temperatures increasing fish growth rates and higher DOC decreasing fish growth rates. This study aimed to investigate whether these relationships could be replicated and still applied years later as global temperatures have continued to increase. I found that fish growth rates and body condition were higher in lower elevations. Fish body condition also increased with chlorophyll-a concentration and decreased with DOC concentration and the [delta]13C signature of fish muscle. These patterns suggest that autochthonous production along with increased terrestrial insect consumption may promote increased body condition. Fish grew faster and had better body condition at warmer temperatures, likely contributing to the higher fish growth seen in lower elevations. My results suggest that two major symptoms of climate change, higher temperatures and greater allochthonous carbon concentrations, will have opposing effects on trout growth and productivity in mountain lakes.

Book excerpt: Brown Trout: Biology, Ecology and Management A comprehensive guide to the most current research, history, genetics and ecology of the brown trout including challenging environmental problems The brown trout is an iconic species across its natural European distribution and has been introduced throughout the World. Brown Trout offers a comprehensive review of the scientific information and current research on this major fish species. While the brown trout is the most sought species by anglers, its introduction to various waters around the world is causing serious environmental problems. At the same time, introduction of exogenous brown trout lineages threats conservation of native gene pools of populations in many regions. The authors summarize the important aspects of the brown trout’s life history and ecology and focus on the impact caused by the species. The text explores potential management strategies in order to maintain numerous damaged populations within its natural distributional range and to ameliorate its impacts in exotic environments. The authors include information on a wide-range of topics such as recent updates in population genetics, evolutionary history, reproductive traits and early ontogeny, life history plasticity in anadromous brown trout and life history of the adfluvial brown trout and much more. This vital resource: Contains the latest research on the biology and ecology of brown trout Includes information on phylogeography, genetics, population dynamics and stock management Spotlights the brown trout’s introduction to regions around the world and the serious environmental impacts Offers a comprehensive review of conservation and management techniques Written for salmonid scientists and researchers, fishery and environmental managers, and students of population genetics, ecology and population dynamics, Brown Trout explores the most recent findings on the history, ecology and sustainability of this much-researched species.

Download or read book Climate Change Impacts on Freshwater Ecosystems written by Martin Kernan and published by Wiley-Blackwell. This book was released on 2010-09-27 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text examines the impact of climate change on freshwater ecosystems, past, present and future. It especially considers the interactions between climate change and other drivers of change including hydromorphological modification, nutrient loading, acid deposition and contamination by toxic substances using evidence from palaeolimnology, time-series analysis, space-for-time substitution, laboratory and field experiments and process modelling. The book evaluates these processes in relation to extreme events, seasonal changes in ecosystems, trends over decadal-scale time periods, mitigation strategies and ecosystem recovery. The book is also concerned with how aspects of hydrophysical, hydrochemical and ecological change can be used as early indicators of climate change in aquatic ecosystems and it addresses the implications of future climate change for freshwater ecosystem management at the catchment scale. This is an ideal book for the scientific research community, but is also accessible to Masters and senior undergraduate students.
Download or read book Effects of Drought on Forests and Rangelands in the United States written by James M. Vose and published by . This book was released on 2016 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: This assessment provides input to the reauthorized National Integrated Drought Information System (NIDIS) and the National Climate Assessment (NCA), and it establishes the scientific foundation needed to manage for drought resilience and adaptation. Focal areas include drought characterization; drought impacts on forest processes and disturbances such as insect outbreaks and wildfire; and consequences for forest and rangeland values. Drought can be a severe natural disaster with substantial social and economic consequences. Drought becomes most obvious when large-scale changes are observed; however, even moderate drought can have long-lasting impacts on the structure and function of forests and rangelands without these obvious large-scale changes. Large, stand-level impacts of drought are already underway in the West, but all U.S. forests are vulnerable to drought. Drought-associated forest disturbances are expected to increase with climatic change. Management actions can either mitigate or exacerbate the effects of drought. A first principal for increasing resilience and adaptation is to avoid management actions that exacerbate the effects of current or future drought. Options to mitigate drought include altering structural or functional components of vegetation, minimizing drought-mediated disturbance such as wildfire or insect outbreaks, and managing for reliable flow of water.
