Book excerpt: The objectives of this study were to determine the influence of land-use and other local and landscape factors on wetland invertebrate diversity, biomass, and taxa composition within depressional wetlands of Oklahoma. Fifty-eight wetlands in north central Oklahoma were sampled for invertebrates during 2009 and 2010. All wetlands were closed depressional, palustrine wetlands. Wetlands were located within annually tilled cropland, improved pastureland, or native rangeland. To determine the influence of land-use on the invertebrate community means were compared for invertebrate diversity, biomass of taxa and functional feeding groups among the land-use practices. Differences in taxa composition between land-use practices were also assessed. To determine the influence of local and landscape factors, linear regression and ordination was used to determine the variables explaining the most variation in invertebrate diversity, the biomass of the most common taxa, and taxa composition. Local factors included vegetation complexity and water quality, while landscape factors included land-use practices and wetland area within 1 and 2 km of study wetlands. Land-use influenced nine invertebrate taxa, three functional feeding groups, as well as invertebrate taxa composition. The majority of the taxa did not significantly respond to land-use practices. However, differences in plant cover, vegetation complexity, and water quality among the land-use practices suggest some degradation of wetlands caused by land-use. High variability among sites may have prevented finding more significant results. Numerous local and landscape factors did significantly explain variation in invertebrate taxa biomass as well as taxa composition. Overall, 24 taxa had the most variation explained with local factors, while seven taxa had the most variation explained by landscape factors. The most variation in taxa composition was explained by local factors. Dominant local factors were vegetation complexity, plant cover, and water depth, while wetland density, hydroperiod diversity, and land-use practices were important landscape factors. The results indicate that management and conservation efforts should consider habitat quality within the wetland, but also wetland habitat availability within the landscape.

Available in PDF, EPUB and Kindle. Book excerpt: Wetlands are among the world’s most valuable and most threatened habitats, and in these crucially important ecosystems, the invertebrate fauna holds a focal position. Most of the biological diversity in wetlands is found within resident invertebrate assemblages, and those invertebrates are the primary trophic link between lower plants and higher vertebrates (e.g. amphibians, fish, and birds). As such, most scientists, managers, consultants, and students who work in the world’s wetlands should become better informed about the invertebrate components in their habitats of interest. Our book serves to fill this need by assembling the world’s most prominent ecologists working on freshwater wetland invertebrates, and having them provide authoritative perspectives on each the world’s most important freshwater wetland types. The initial chapter of the book provides a primer on freshwater wetland invertebrates, including how they are uniquely adapted for life in wetland environments and how they contribute to important ecological functions in wetland ecosystems. The next 15 chapters deal with invertebrates in the major wetlands across the globe (rock pools, alpine ponds, temperate temporary ponds, Mediterranean temporary ponds, turloughs, peatlands, permanent marshes, Great Lakes marshes, Everglades, springs, beaver ponds, temperate floodplains, neotropical floodplains, created wetlands, waterfowl marshes), each chapter written by groups of prominent scientists intimately knowledgeable about the individual wetland types. Each chapter reviews the relevant literature, provides a synthesis of the most important ecological controls on the resident invertebrate fauna, and highlights important conservation concerns. The final chapter synthesizes the 15 habitat-based chapters, providing a macroscopic perspective on natural variation of invertebrate assemblage structure across the world’s wetlands and a paradigm for understanding how global variation and environmental factors shape wetland invertebrate communities.

Available in PDF, EPUB and Kindle. Book excerpt: Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

This book was released on 2012 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vernal pools are temporary wetlands and local-scale biodiversity hot spots for a variety of amphibians, macroinvertebrates, and plants because their seasonal drying prevents the establishment of predatory fish populations. Vernal pools are often of conservation concern because of the amphibian populations; however, the emphasis on these organisms often eclipses the macroinvertebrates, which are important predators, prey, and nutrient cyclers in wetlands and the surrounding habitat. Hydroperiod and water chemistry are thought to be the primary regulators of vernal pool macroinvertebrates, but the surrounding habitat also affects these organisms. Specifically, canopy cover and forest composition can alter the autochthonous and allochthonous carbon sources for wetland food webs. My research objectives were to understand how variations in these factors affect macroinvertebrate diversity and community composition. In 2009, I conducted a field survey of fifteen vernal pools that varied in area, depth, hydroperiod, canopy and surrounding land use. I measured several habitat conditions, assessed the biotic communities of these wetlands, and found that canopy cover influenced bottom-up productivity and macroinvertebrate diversity. I used the results of this study to determine how known macroinvertebrate communities respond to variation in canopy cover in mesocosm wetlands. The low canopy treatments sustained the highest macroinvertebrate abundance, family richness, and Shannon diversity, as greater algal productivity increased resources available to support the macroinvertebrate communities. I conducted a second mesocosm experiment to explore how variation in canopy cover (low or high) and litter species (oak, maple, or a mixture of the two litters) affect vernal pool macroinvertebrates. Macroinvertebrate abundance and family richness were greater under low canopy and with oak litter, but the effects of canopy often depended on litter species. Canopy limits the amount of light that reaches a wetland, but litter and its impact on dissolved organic carbon (DOC) limit light transmittance and producer communities. Because forest composition and structure are changing from anthropogenic activities, these results suggest they will also alter the food webs of vernal pools. However, as some organisms utilize pools considered to be low quality for macroinvertebrates, vernal pools should be protected in a variety of habitat contexts to preserve regional species diversity.

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquatic invertebrates play a key ecological role in riverine biogeochemical cycles, transferring nutrients incorporated from diverse food sources (e.g. algae or terrestrial detritus) to resident and migratory predators within aquatic and riparian ecosystems. Agricultural land use affects stream aquatic invertebrate communities, generally reducing their diversity and the prevalence of sensitive taxa as a result of the introduction of agro-chemicals (nutrients and pesticides) and other environmental stressors (fine sediments and flow). This thesis aims to understand how agricultural land use affects aquatic invertebrate communities and the role these communities play in the storage and transfer of nutrients within stream food webs. To accomplish this, streams in northwestern New Brunswick were sampled over a three-year period (2010 –2012) for water nutrient concentrations, site characteristics, and aquatic invertebrate biomass and nutrient content. The first study established associations between agricultural land use and stream water nutrient concentrations (positive), aquatic invertebrate community diversity and sensitivity (negative), and total community biomass (negative).The second study determined that the nitrogen and phosphorus content within aquatic invertebrate communities decreased and increased, respectively, as aquatic invertebrate communities lost diversity and sensitive taxa. Using data from a subset of these sites and additional ones sampled in 2012, the final study validated the results of the previous studies and showed similar effects of agricultural land use on aqueous nutrient concentrations, aquatic invertebrate communities, and community nutrient content. Further, this study showed that the quantity of nitrogen stored within the aquatic invertebrate community decreased with increasing agricultural land use while the quantity of phosphorus was unaffected. Together these results demonstrate that as aquatic invertebrate communities change their composition in response to increasing agricultural land cover in the catchment, the amount of nutrients stored by the community decreases. This reduction in nutrient storage capacity likely results from shifts in life history strategies in the aquatic invertebrate community. More broadly, these findings suggest that agriculture affects how aquatic invertebrates cycle nutrients in riverine food webs, which may in turn impact aquatic and terrestrial predators that rely on these communities.

Book excerpt: This long-anticipated reference and sourcebook for CaliforniaÕs remarkable ecological abundance provides an integrated assessment of each major ecosystem typeÑits distribution, structure, function, and management. A comprehensive synthesis of our knowledge about this biologically diverse state, Ecosystems of California covers the state from oceans to mountaintops using multiple lenses: past and present, flora and fauna, aquatic and terrestrial, natural and managed. Each chapter evaluates natural processes for a specific ecosystem, describes drivers of change, and discusses how that ecosystem may be altered in the future. This book also explores the drivers of CaliforniaÕs ecological patterns and the history of the stateÕs various ecosystems, outlining how the challenges of climate change and invasive species and opportunities for regulation and stewardship could potentially affect the stateÕs ecosystems. The text explicitly incorporates both human impacts and conservation and restoration efforts and shows how ecosystems support human well-being. Edited by two esteemed ecosystem ecologists and with overviews by leading experts on each ecosystem, this definitive work will be indispensable for natural resource management and conservation professionals as well as for undergraduate or graduate students of CaliforniaÕs environment and curious naturalists.

Book excerpt: The Environmental Monitoring and Assessment Program was created by EPA to develop the capability for tracking the changing conditions of our natural resources and to give environmental policy the advantages ofa sound scientific understanding of trends. Former EPA Administrators recognized early that contemporary monitoring programs could not even quantify simple unknowns like the number of lakes suffering from acid rain, let along determine if national control policies were benefiting these lakes. Today, adding to acidification impacts are truly complex problems such as determining the effects of climate change, of increases in ultraviolet light, toxic chemicals, eutrophication and critical habitat loss. Also today, the Government Performance and Results Act seeks to have agencies develop performance standards based on results rather than simply on levels of programmatic activities. The charge to EMAP of ecosystems is, therefore, the same today as it was a with respect to measuring the condition decade ago. We welcome the increasing urgency for sound scientific monitoring methods and data by efforts to protect and improve the environment. Systematic nationwide monitoring of natural resources is more than anyone program can accomplish, however. In an era of declining budgets, it is crucial that monitoring programs at all levels of government coordinate and share environmental data. EMAP resources are dwarfed by the more than $500 million spent on federal monitoring activities each year.

Available in PDF, EPUB and Kindle. Book excerpt: The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.
