Book Description :

Toxic chemicals can exert effects on all levels of the biological hierarchy, from cells to organs to organisms to populations to entire ecosystems. However, most risk assessment models express their results in terms of effects on individual organisms, without corresponding information on how populations, groups of species, or whole ecosystems may respond to chemical stressors. Ecological Modeling in Risk Assessment: Chemical Effects on Populations, Ecosystems, and Landscapes takes a new approach by compiling and evaluating models that can be used in assessing risk at the population, ecosystem, and landscape levels. The authors give an overview of the current process of ecological risk assessment for toxic chemicals and of how modeling of populations, ecosystems, and landscapes could improve the status quo. They present a classification of ecological models and explain the differences between population, ecosystem, landscape, and toxicity-extrapolation models. The authors describe the model evaluation process and define evaluation criteria. Finally, the results of the model evaluations are presented in a concise format with recommendations on modeling approaches to use now and develop further. The authors present and evaluate various models on the basis of their realism and complexity, prediction of relevant assessment endpoints, treatment of uncertainty, regulatory acceptance, resource efficiency, and other criteria. They provide models that will improve the ecological relevance of risk assessments and make data collection more cost-effective. Ecological Modeling in Risk Assessment serves as a reference for selecting and applying the best models when performing a risk assessment.

Book Description :

Understanding and being able to predict fluvial processes is one of the biggest challenges for hydraulics and environmental engineers, hydrologists and other scientists interested in preserving and restoring the diverse functions of rivers. The interactions among flow, turbulence, vegetation, macroinvertebrates and other organisms, as well as the transport and retention of particulate matter, have important consequences on the ecological health of rivers. Managing rivers in an ecologically friendly way is a major component of sustainable engineering design, maintenance and restoration of ecological habitats. To address these challenges, a major focus of River Flow 2016 was to highlight the latest advances in experimental, computational and theoretical approaches that can be used to deepen our understanding and capacity to predict flow and the associated fluid-driven ecological processes, anthropogenic influences, sediment transport and morphodynamic processes. River Flow 2016 was organized under the auspices of the Committee for Fluvial Hydraulics of the International Association for Hydro-Environment Engineering and Research (IAHR). Since its first edition in 2002, the River Flow conference series has become the main international event focusing on river hydrodynamics, sediment transport, river engineering and restoration. Some of the highlights of the 8th International Conference on Fluvial Hydraulics were to focus on inter-disciplinary research involving, among others, ecological and biological aspects relevant to river flows and processes and to emphasize broader themes dealing with river sustainability. River Flow 2016 (extended abstract book 854 pages + full paper CD-ROM 2436 pages) contains the contributions presented during the regular sessions covering the main conference themes and the special sessions focusing on specific hot topics of river flow research, and will be of interest to academics interested in hydraulics, hydrology and environmental engineering.

Book Description :

Clear Lake is the largest fresh water body in California. It has three arms: Upper Arm, Oaks Arm, and Lower Arm. Though each of them can be treated as an individual lake, the three arms still have similar phytoplankton bloom situations. Clear Lake keeps contributing to Lake County and surrounding region's economy as well as environmental and ecological locality. However, since the 1930's, cyanobacteria have been blooming at certain years. Since then, the government and the public have paid high attention on the reparation of water quality in Clear Lake. Notably, Clean Water Act (CWA) and Total Maximum Daily Loads (TMDLs) projects are vital water restoration proposals. Clear Lake watershed was selected as the one that should be paid attention to meet water quality standards. US Environmental Protection Agency (EPA) launched a collection of models called "TMDL Modeling Toolbox" for the purpose of developing TMDLs. Therefore, it is important to use efficient models to make Clear Lake realize water restoration target. AQUATOX is a comprehensive aquatic ecosystem model with good tested ecological risk methodology. Abundant model studies can be achieved due to the multiple functions in AQUATOX. However, the default Clear Lake study attached in AQUATOX package was roughly calibrated. The main purpose of this paper is to calibrate the AQUATOX Clear Lake model to maximally meet precision under the premise of achieving generality and realism. And then, through in depth study of Clear Lake water quality history and AQUATOX model, this paper proposes possible further studies about model application based on on-processing projects. Through analyses, this paper results as below: (1) Based on the attached study model of Clear Lake California in AQUATOX, this paper fixed values of site characteristic, boundary conditions and certain important state variables' parameters according to academic references and repeated model tests. The driving variables such as flow, temperature, light and nutrients are important to the precision of simulation. Sediment diagenesis sub model plays an important role on simulating nutrients peaks in the end of summer, especially for phosphate. Plus, cyanobacteria parameters are critical for the new model behavior since cyanobacteria biomass and nutrients are sensitive to that parameter changing. (2) After calibration, nitrate, phosphate and Blue-Green algae model outputs have great improvements. The modeled nitrate concentration has low values in summer about 0.2mg/l because of algae bloom, and then returns to peaks in winter around 0.6mg/l as the highest. Phosphate output falls close to zero in summer and hits peak at 0.3mg/l in the end of summer 1970, and then repeat similar trend each year. Blue-Green algae output starts to increase in May and keeps in a high concentration from 6 to 8 mg/l dry. The bloom period ends in October. Ammonia output stays at a low concentration under 0.1 mg/l. Bottom dissolved oxygen falls to zero in summer due to seasonal stratification. Both nutrients and algae model predication are in good agreement with observed data. (3) Multiple sensitivity and uncertainty analyses were run to achieve better parameter calibration results. Overlap test shows the relative bias (rB) value of phosphate and algae are both close to zero, but the one of nitrate hits 1 because of the relatively high nitrate concentration in summer. Nitrate, phosphate and algae all have F value close to 1. The test result with rB close to 0 and F close to 1 shows the modified model has good fitness to observed data. Also, the cumulative distribution test shows both nitrate and phosphate have D-stat value that is less than D-crit, which means these two model distributions are not significantly different with the observed data trend. Precise driving variables data are preferred if better accuracy was needed for the model running. Modeling lake stratification in summer and open the sediment digenesis sub model are essential to phosphorus simulation behavior.

Book Description :

Fish and other seafood have always been considered as an important part of human diet and have also long been recognized as a health-promoting food for human nutrition. However, managing aquatic food resources remains a challenge as the human population is expanding and overfishing poses a threat to fishing reserves in several areas. Aquaculture is the alternative solution for food production from the sea. According to the FAO, aquaculture is probably the fastest growing food-producing sector and can be a sustainable solution for fish production. In order to maximize marine food production and achieving sustainable management of the aquatic environment, knowledge about aspects of fisheries and aquatic animal health is very important. Trends in Fisheries and Aquatic Animal Health covers some basic and applied topics in fishery management and fish health with a focus on European regions. The textbook is a combination of reviews and research articles. Topics covered in the book include challenges in fishery management, environmental impacts on fisheries, fish health (pharmacology, histopathology, stress response), telemetry techniques in fisheries research, and specific case studies of regional marine species in localized fisheries. This textbook is a useful resource for graduates and professionals involved in advanced training courses for aquaculture and fishery management.
