This book was released on 2015 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historical meteorological and hydrological data were assembled to review the influence of changes in these environmental factors on patterns of adult Sockeye migration in the Babine River, British Columbia. Regional air temperature data collected from Environment Canada meteorological stations were statistically related to intermittent water temperature time-series (2003-2014) recorded at the Babine fish fence to hind-cast daily water temperature in Babine River for 1910-2014. Flow data from two hydrometric stations in the Babine watershed were statistically-related to construct a continuous daily discharge time-series for 1945-2014. A stratified categorical frequency analysis of daily migration rates versus water temperature and flow conditions, lagged 0-7 days earlier, was used to discern the most likely combination of threshold values for temperature, discharge and associated time lags contributing to daily fence count variation.

This book was released on 2017 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Historical meteorological, water discharge and water temperature data were assembled to review the influence of changes in these environmental factors on daily migration patterns of adult Sockeye en route to their Chilko River spawning grounds (1975-2012), a major tributary to the Chilcotin River, British Columbia. Air temperature data, adjusted and homogenized for climate analyses, were obtained for a regional meteorological station (at Williams Lake), and statistically related to intermittent water temperature time-series (spanning 1996-2012) in the Chilko and Chilcotin rivers to hind-cast daily mean water temperature for 1940-2012 at key sites along the migration route. Flow data from two hydrometric stations in the watershed were statistically-related to construct continuous daily discharge time-series for 1927-2012 at the same sites. A stratified categorical frequency analysis of daily water temperature and flow levels versus standardized daily migration lagged 0-20 days earlier was used to discern the most likely combination of threshold values for temperature, discharge, and time lag contributing to daily migration rate variation. The resulting critical thresholds were applied in exceedance analyses to review trends in flow & temperature events pertinent to Chilko Sockeye migration"--Abstract, p. v.

This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Pacific salmon carry out long distance spawning migrations from ocean feeding grounds to natal freshwater streams. Because many salmon rivers are dammed, fishways are required to enable individuals to pass through dams and reach upstream spawning areas. However, many fishways are ineffective, preventing or delaying upstream passage, suggesting a need to monitor and evaluate these facilities. I conducted a literature review of studies evaluating the effectiveness of fishways to assess what taxa and life-stages have been studied, the questions asked during evaluation, and how these varied by time or geographic location. The majority of studies focused on adult fishes (68%) and the order Salmoniformes (58%). Many studies evaluated exogenous mechanisms of passage failure, such as environmental or structural factors (69%). Few studies examined endogenous (i.e. physiological) factors or post-passage consequences, information that is necessary to understand passage failure and inform mitigation strategies. A field study was carried out to evaluate the impact of a dam and fishway on the spawning migrations of sockeye salmon in the Seton-Anderson watershed in British Columbia. I used acoustic telemetry, non-lethal biopsies, and an experimental approach, releasing fish either up- or down-stream of the dam and comparing behaviour and mortality between the two groups. Fishway passage efficiency was 80% and most failure was associated with failing to locate the entrance. Attraction to the fishway entrance varied with water discharge volume from the dam, with the longest delays and highest failure rate at the highest discharge. Fish released downstream of the dam suffered higher mortality in lakes upstream of the fishway (27%) compared to fish released downstream of the dam (7%), suggesting post-passage consequences that reduce survival. Sockeye migrating through two thermally stratified lakes upstream of the dam were used as models to investigate the hypothesis that temperatures.

Book Synopsis Water, Cultural Diversity, and Global Environmental Change by : Barbara Rose Johnston
Download or read book Water, Cultural Diversity, and Global Environmental Change written by Barbara Rose Johnston and published by Springer Science & Business Media. This book was released on 2011-12-07 with total page 594 pages. Available in PDF, EPUB and Kindle. Book excerpt: Co-published with UNESCO A product of the UNESCO-IHP project on Water and Cultural Diversity, this book represents an effort to examine the complex role water plays as a force in sustaining, maintaining, and threatening the viability of culturally diverse peoples. It is argued that water is a fundamental human need, a human right, and a core sustaining element in biodiversity and cultural diversity. The core concepts utilized in this book draw upon a larger trend in sustainability science, a recognition of the synergism and analytical potential in utilizing a coupled biological and social systems analysis, as the functioning viability of nature is both sustained and threatened by humans.
Book Synopsis Mediterranean Coastal Lagoons by : S. Cataudella
Download or read book Mediterranean Coastal Lagoons written by S. Cataudella and published by Food & Agriculture Organization of the UN (FAO). This book was released on 2015 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Mediterranean region hosts around 400 coastal lagoons, covering a surface of over 641 000 ha differing in both their typology and use. Fisheries and various forms of aquaculture have been traditionally carried out in Mediterranean coastal lagoons since ancient times and are part of the cultural heritage of the region. Traditional lagoon management linked to extensive aquaculture and fish harvesting has certainly contributed, over time, to preserve these peculiar ecosystems, although much of the coastal lagoon areas have progressively disappeared due to land reclamation and other uses. Recently, coastal lagoons have become a relevant environmental concern: land claiming, pollution and the lack of management, among other factors, have strongly modified both the structure and functioning of these sensitive coastal ecosystems. In particular, the management of traditional aquaculture and capture fisheries activities has been identified as the main instrument to maintain lagoons' ecological features and to prevent the degradation of their sensitive habitats, both from an environmental and socioeconomic point of view. To guarantee the sustainability of aquaculture and capture fisheries in lagoons, proper management plans should be established so as to ensure the preservation of both biodiversity and local knowledge. This should also be considered as a fundamental pillar for any programme aiming at the preservation and restoration of lagoons' environment."--Publisher's description.

Book Synopsis Lagoa Santa Karst: Brazil's Iconic Karst Region by : Augusto S. Auler
Download or read book Lagoa Santa Karst: Brazil's Iconic Karst Region written by Augusto S. Auler and published by Springer Nature. This book was released on 2020-01-22 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the Lagoa Santa Karst, which has been internationally known since the pioneering studies of the Danish naturalist Peter Lund in the early 1800s. It covers the speleogenesis, geology, vegetation, fauna, hydrogeology, geomorphology, and anthropogenic use of the Lagoa Santa Karst and is the first English-language book on this major karst area. The area, which has been at the heart of the debate on the origin and age of human colonization in the Americas, is characterized by a classical and scenic karst landscape with limestone cliffs, karst lakes and karst plains, in addition to numerous solution dolines. More than 1,000 caves have been documented in the area, many with significant archeological and paleontological value. Despite its great importance, the Lagoa Santa Karst faces severe environmental threats due to limestone mining and the expansion of the metropolis of Belo Horizonte and its surrounding towns. The growing recognition of the area’s remarkable significance has led to increasing concern, and a number of protected areas have now been established, improving the conservation status of this landmark karst area.
