Available in PDF, EPUB and Kindle. Book excerpt: A deterministic, one dimensional, unsteady lake water temperature model was modified and validated to simulate the seasonal (spring to fall) temperature statification structure over a wide range of lake morphometries, trophic and meteorological conditions. Model coefficients related to hypolimnetic eddy diffusivity, light attenuation, wind sheltering, ad convective heat transfer were generalized using theoretical and empirical extensions. Propagation of uncertainty in the lake temperature model was studied using a vector state-space method. The output uncertainty was defined as the result of deviations of meteorological variables from their mean values. Surface water temperatures were affected by uncertain meteorological forcing. Air temperture and dew point temperature fluctuations had significant effects on lake temperature uncertainty. The method presents a useful alternative for studying long-term averages and variability of the water temperature structure in lakes due to variable meteorological forcing. The lake water temperature model was linked to a daily meteorological data base to simulate daily water temperature in several specific lakes as well as 27 lake classes characteristic for the north central US. Case studies of lake water temperature and stratification response to variable climate were made in a particulary warm year (1988) and a more normal one (1971). A regional analysis was conducted for 27 lake classes over a period of twenty-five years (1955-1979). Output from a global climate model (GISS) was used to modify te meteorological data base to account for a doubling of atmospheric CO2. The simulations predict that after climate change: 1) epilimnetic water temperatures will be higher but will increase less than air temperature, 2) hypolimnetic temperatures in seasonally stratified dimictic lakes will be largely unchanged and in some cases lower than at present, 3) evaporative water loss will be increased by as much as 300 mm for the open water season, 4) onset of stratification will occur earlier and overturn will occur later in the season, and 5) overall lake stability will become greater in spring and sumer.

Available in PDF, EPUB and Kindle. Book excerpt: Lake littoral zones play an integral role in production, community assembly, and the coupling of ecosystem components. These areas are critical habitat for many species due to its structural complexity in the form of abundant habitat. Because these areas are essential components of lakes, I explore several drivers in littoral zones. I have taken cross-system comparisons, long-term observations, and detailed within lake observations and combined them with modeling to ask the following questions about littoral zone habitat and communities: what are strong drivers of littoral zone habitat quality, and what is the role of this habitat? In Chapter 1, I quantify lake water level changes during a multiyear drought. These lakes experienced nearly identical weather and climate but had divergent responses in terms of water level loss. This variability was explained by lake and landscape characteristics that served as proxies for a lakes' hydrologic budget, which ultimately mediate the response to climate. I found that seepage lakes responded the most dramatically, and the water level changes translated to more substantial losses of coarse woody habitat (CWH). Thus, droughts and the associated impacts on habitat may be a regional driver of change. In Chapter 2, I characterized fish community and habitat change across a lakeshore residential development (LRD) gradient. I quantified the typical habitat changes associated with increasing LRD, including decreased CWH and riparian forest density and alterations in littoral substrates. Additionally, I identified winners and losers in the fish community across an LRD gradient. I found that fish with similar responses to LRD had vastly different habitat associations, suggesting that other drivers associated with LRD are likely also affecting communities. In Chapter 3, I examine the spatiotemporal dynamics of an invasive rusty crayfish (Faxonius rusticus) and native virile crayfish (F. virilis) population in the context of a whole-lake experiment. Eight years of rusty crayfish removals successfully suppressed a high abundance population, which allowed macrophytes, macroinvertebrates, Lepomis sunfishes, and virile crayfish to recover. In examining the within lake spatiotemporal dynamics of both species, I learn that the virile crayfish recovery was highly localized, and influenced by littoral habitat and the abundance of rusty crayfish.

Available in PDF, EPUB and Kindle. Book excerpt: This book is an outgrowth of research contributions and teaching experiences by all the authors in applying modern fluid mechanics to problems of pollutant transport and mixing in the water environment. It should be suitable for use in first year graduate level courses for engineering and science students, although more material is contained than can reasonably be taught in a one-year course, and most instructors will probably wish to cover only selected potions. The book should also be useful as a reference for practicing hydraulic and environmental engineers, as well as anyone involved in engineering studies for disposal of wastes into the environment. The practicing consulting or design engineer will find a thorough explanation of the fundamental processes, as well as many references to the current technical literature, the student should gain a deep enough understanding of basics to be able to read with understanding the future technical literature evolving in this evolving field.

Book excerpt: This book is a product of the joint JGOFS (Joint Global Ocean Flux Study)/LOICZ (Land–Ocean Interactions in the Coastal Zone) Continental Margins Task Team which was established to facilitate continental margins research in the two projects. It contains signi cant information on the physical, biogeochemical, and ecosystems of continental margins nationally and regionally and provides a very valuable synthesis of this information and the physical, biogeochemical and ecosystem processes which occur on continental margins. The publication of this book is timely as it provides a very strong foundation for the development of the joint IMBER (Integrated Marine Biogeochemistry and Ecosystems Research)/LOICZ Science Plan and Implemen- tion Strategy for biogeochemical and ecosystems research in the continental margins and the impacts of global change on these systems. This initiative will move forward integrated biogeochemical and ecosystems research in the continental margins. We thank all the contributors to this volume and especially Kon-Kee Liu who has dedicated a great deal of time to ensuring a high-quality book is published. IMBER Scienti c Steering Committee Julie Hall LOICZ Scienti c Steering Committee Jozef Pacyna v 1 Preface In general, interfaces between the Earth’s larger material reservoirs (i. e. , the land, atmosphere, ocean, and sediments) are important in the control of the biogeoche- cal dynamics and cycling of the major bio-essential elements, including carbon (C), nitrogen (N), phosphorus (P), sulfur (S), and silicon (Si), found in organic matter and the inorganic skeletons, shells, and tests of benthic and marine organisms.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents the first unified conceptual and statistical framework for understanding the evolution of reproductive strategies. Using the concept of the opportunity for sexual selection, the authors illustrate how and why sexual selection, though restricted to one sex and opposed in the other, is one of the strongest and fastest of all evolutionary forces. They offer a statistical framework for studying mating system evolution and apply it to patterns of alternative mating strategies. In doing so, they provide a method for quantifying how the strength of sexual selection is affected by the ecological and life history processes that influence females' spatial and temporal clustering and reproductive schedules. Directly challenging verbal evolutionary models that attempt to explain reproductive behavior without quantitative reference to evolutionary genetics, this book establishes a more solid theoretical foundation for the field. Among the weaknesses the authors find in the existing data is the apparent ubiquity of condition-dependent mating tactics. They identify factors likely to contribute to the evolution of alternative mating strategies--which they argue are more common than generally believed--and illustrate how to measure the strength of selection acting on them. Lastly, they offer predictions on the covariation of mating systems and strategies, consider the underlying developmental biology behind male polyphenism, and propose directions for future research. Informed by genetics, this is a comprehensive and rigorous new approach to explaining mating systems and strategies that will influence a wide swath of evolutionary biology.
