Book excerpt: Southern Green Bay, Lake Michigan is one of the most productive ecosystems in the Great Lakes and has historically been subjected to a wide range of stressors, yet little is known about the current macroinvertebrate community structure. The most recent comprehensive assessment of benthic fauna was by Markert (1982) in 1978. The objectives of this project were to describe the current macroinvertebrate community, examine changes since 1978, and identify major environmental drivers of benthic community compositions. In total, 258 stations were surveyed, including 97 that were also sampled in 1978, 100 that were added to increase spatial resolution, and 61 that were subjected to periodic hypoxia. I collected 95 macroinvertebrate taxa in southern Green Bay with the community dominated by the eurytopic midge Chironomus and immature tubificid worms. Nonmetric multidimensional scaling (NMDS) ordination and indicator analyses distinguished contemporary and historical communities and revealed shifts in benthic macroinvertebrate structure; although oligochaete worms and chironomids remained dominant over time, Chironomus abundance increased and characterized the contemporary community, whereas the benthos were historically more diverse. The magnitude of temporal change varied regionally with larger differences concentrated in southern middle bay and the inner bay remaining comparable to 1978. Contemporary assemblages are driven primarily by productivity, substrate type, and hypoxia, according to NMDS ordinations. Regular benthic monitoring should continue to evaluate biological responses to environmental stressors and assess management actions.

Book excerpt: Experimentation is a dominant approach in contemporary ecological research, pervading studies at all levels of biological organization and across diverse taxa and habitats. Experimental Ecology assembles an eminent group of ecologists who synthesize insights from these varied sources into a cogent statement about experimentalism as an analytical paradigm, placing experimentation within the larger framework of ecological investigation. The book discusses diverse experimental approaches ranging from laboratory microcosms to manipulation of entire ecosystem, illustrating the myriad ways experiments strengthen ecological inference. Experimental ecologists critique their science to move the field forward on all fronts: from better designs, to better links between experiments and theory, to more realism in experiments targeted at specific systems and questions.
Download or read book Food Webs written by Gary A. Polis and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reflecting the recent surge of activity in food web research fueled by new empirical data, this authoritative volume successfully spans and integrates the areas of theory, basic empirical research, applications, and resource problems. Written by recognized leaders from various branches of ecological research, this work provides an in-depth treatment of the most recent advances in the field and examines the complexity and variability of food webs through reviews, new research, and syntheses of the major issues in food web research. Food Webs features material on the role of nutrients, detritus and microbes in food webs, indirect effects in food webs, the interaction of productivity and consumption, linking cause and effect in food webs, temporal and spatial scales of food web dynamics, applications of food webs to pest management, fisheries, and ecosystem stress. Three comprehensive chapters synthesize important information on the role of indirect effects, productivity and consumer regulation, and temporal, spatial and life history influences on food webs. In addition, numerous tables, figures, and mathematical equations found nowhere else in related literature are presented in this outstanding work. Food Webs offers researchers and graduate students in various branches of ecology an extensive examination of the subject. Ecologists interested in food webs or community ecology will also find this book an invaluable tool for understanding the current state of knowledge of food web research.
Download or read book Quagga and Zebra Mussels written by Thomas F. Nalepa and published by CRC Press. This book was released on 2013-10-25 with total page 820 pages. Available in PDF, EPUB and Kindle. Book excerpt: The introduction and rapid spread of two Eurasian mussel species, Dreissena polymorpha (zebra mussel) and Dreissena rostriformis bugensis (quagga mussel), in waters of North America has caused great concern among industrial and recreational water users. These invasive species can create substantial problems for raw water users such as water treatment facilities and power plants, and they can have other negative impacts by altering aquatic environments. In the 20 years since the first edition of this book was published, zebra mussels have continued to spread, and quagga mussels have become the greater threat in the Great Lakes, in deep regions of large lakes, and in the southwestern Unites States. Quagga mussels have also expanded greatly in eastern and western Europe since the first book edition was published. Quagga and Zebra Mussels: Biology, Impacts, and Control, Second Edition provides a broad view of the zebra/quagga mussel issue, offering a historic perspective and up-to-date information on mussel research. Comprising 48 chapters, this second edition includes reviews of mussel morphology, physiology, and behavior. It details mussel distribution and spread in Europe and across North America, and examines policy and regulatory responses, management strategies, and mitigation efforts. In addition, this book provides extensive coverage of the impact of invasive mussel species on freshwater ecosystems, including effects on water clarity, phytoplankton, water quality, food web changes, and consequences to other aquatic fauna. It also reviews and offers new insights on how zebra and quagga mussels respond and adapt to varying environmental conditions. This new edition includes seven video clips that complement chapter text and, through visual documentation, provide a greater understanding of mussel behavior and distribution.
