Book excerpt: Oyster reef restoration may enhance the production of ecologically or economically important fish species, an ecosystem service, by providing refuge and foraging habitat. Predicting the effects of oyster habitat restoration on fisheries production in Chesapeake Bay requires a better understanding of fish habitat use, trophic dynamics, and the processes leading to production on a habitat-scale. The objective of this thesis was to evaluate the influence of restored subtidal oyster reefs on the abundance and foraging patterns of mobile estuarine fishes. Specifically, I compared the 1) abundance, 2) stomach fullness, 3) diet composition, and 4) daily consumption rate of fishes collected from restored oyster reef habitat and from unstructured (control) habitat in the Lynnhaven River System (LRS), Virginia, a tributary of Chesapeake Bay. I sampled fishes from April – October 2016 to assess seasonal abundance and diet trends using multi-panel gill nets, and conducted 24-hour sampling events in July and September 2016 to assess daily foraging patterns and estimate habitat-specific consumption rates. The most abundant non-filter feeding fishes collected all came from the Sciaenid (drum) family: spot (Leiostomus xanthurus), silver perch (Bairdiella chrysoura), and Atlantic croaker (Micropogonias undulatus). Overall catch in oyster reef habitat was reduced relative to unstructured bottom, but species-level responses to habitat type varied. Stomach fullness trends varied by species but were associated with habitat type. Benthic prey dominated the diet of all three species, and evidence of habitat-related shifts in diet composition were apparent. Reef-affiliated prey contributed most prominently to silver perch, comprising nearly 30 – 50 % by weight. The daily consumption rate and total daily caloric intake of silver perch foraging in oyster reef habitat were nearly double the estimates from control habitat. The results suggest restored oyster reefs influence habitat use and foraging behavior in species-specific manners, likely a result of differences in functional morphology and prey preference. Restored oyster reefs in the LRS likely act as valuable forage habitat for silver perch, an important trophic link in coastal and estuarine systems. Developing realistic estimates of fisheries production on a habitat-scale requires studying species-specific trophic dynamics. Empirical estimates of the processes contributing to production are necessary to better understand the functional role of restored oyster reefs in shallow estuarine and coastal systems, and the ecosystem services these reefs may provide.

This book was released on 2004-03-09 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonnative Oysters in the Chesapeake Bay discusses the proposed plan to offset the dramatic decline in the bay's native oysters by introducing disease-resistant reproductive Suminoe oysters from Asia. It suggests this move should be delayed until more is known about the environmental risks, even though carefully regulated cultivation of sterile Asian oysters in contained areas could help the local industry and researchers. It is also noted that even though these oysters eat the excess algae caused by pollution, it could take decades before there are enough of them to improve water quality.

This book was released on 2020-06-16 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume examines the applicability of nature-based solutions in ecological restoration practice and in contemporary landscape architecture by bringing together ecology and architecture in the built environment. Green infrastructure is used to address urban challenges such as climate change adaptation, disaster risk reduction, and stormwater management. In addition, thermal comfort nature-based solutions reintroduce critical connections between natural and urban systems. In light of ongoing developments in sustainable urban development, the goal is a paradigm shift towards a landscape that restores and rehabilitates urban ecosystems. The ten contributions to this book examine a wide range of successful cases of designing healthier, greener and more resilient landscapes in different geographical contexts, from the United States of America and Brazil, through various European regions, to Singapore and China. While some chapters attempt to conceptualize the interconnections between cities and nature, others clearly have an empirical focus. Therefore, this volume provides a rich body of work and acts as a starting point for further studies on restoration of ecosystems and integrative policies such as the United Nations Sustainable Development Goals.

Book excerpt: Coasts and Estuaries: The Future provides valuable information on how we can protect and maintain natural ecological structures while also allowing estuaries to deliver services that produce societal goods and benefits. These issues are addressed through chapters detailing case studies from estuaries and coastal waters worldwide, presenting a full range of natural variability and human pressures. Following this, a series of chapters written by scientific leaders worldwide synthesizes the problems and offers solutions for specific issues graded within the framework of the socio-economic-environmental mosaic. These include fisheries, climate change, coastal megacities, evolving human-nature interactions, remediation measures, and integrated coastal management. The problems faced by half of the world living near coasts are truly a worldwide challenge as well as an opportunity for scientists to study commonalities and differences and provide solutions. This book is centered around the proposed DAPSI(W)R(M) framework, where drivers of basic human needs requires activities that each produce pressures. The pressures are mechanisms of state change on the natural system and Impacts on societal welfare (including well-being). These problems then require responses, which are the solutions relating to governance, socio-economic and cultural measures (Scharin et al 2016). - Covers estuaries and coastal seas worldwide, integrating their commonality, differences and solutions for sustainability - Includes global case studies from leading worldwide contributors, with accompanying boxes highlighting a synopsis about a particular estuary and coastal sea, making all information easy to find - Presents full color images to aid the reader in a better understanding of details of each case study - Provides a multi-disciplinary approach, linking biology, physics, climate and social sciences

Available in PDF, EPUB and Kindle. Book excerpt: In addition to its value as a fisheries resource, the eastern oyster Crassostrea virginica, is a reef building, cornerstone species that provides ecosystem services to the environment. Oysters provide habitat for associated resident and transient species. With widespread declines in oyster populations, restoration efforts have focused on improving oyster stocks and enhancing the ecosystem services they provide. Community-based oyster restoration programs engage the public and local community in planning, construction and/or monitoring of restoration projects. Since 2007, a K-12 student centered community-based restoration venture, Project PORTS, Promoting Oyster Restoration Through Schools, has been working to educate students, promote stewardship values, and enhance oyster habitat in the Delaware Bay. The overarching goals of the present study were to (1) assess fish and macroinvertebrate utilization on the Project PORTS community-created, subtidal, low-relief oyster restoration area in the Delaware Bay, and (2) convert the data collected into a STEM (Science, Technology, Engineering and Mathematics) activity that can be implemented in the classroom. I examined six subtidal natural oyster reefs of varying oyster densities and one community-based restoration reef as habitat for fishes and invertebrates. Sampling methods on these low-relief reefs consisted of otter trawl tows and benthic habitat tray collections. Results revealed that the enhancement area supported a diverse faunal community consistent with nearby, natural oyster habitats. Data collected during the field study were then transformed into an educational lesson plan, "One Fish, Two Fish- Assessing Habitat Value of Restored Oyster Reefs", that fulfilled national and state (NJ) curriculum standards. The lesson was piloted in a middle school classroom and student learning was evaluated through summative assessments pre and post-participation in the activity. Results of the assessments indicated that students made strong gains in knowledge of oyster ecology and improved analytical skills by graphing data. This dual interest study demonstrated that a novel education program with a local, real-world connection positively enhanced crucial estuarine habitat while expanding STEM knowledge and skills of participating students.

Available in PDF, EPUB and Kindle. Book excerpt: We evaluated the progress of several oyster restoration efforts of varying ages in three tidal tributaries of Chesapeake Bay, the Rappahannock, the Piankatank and Great Wicomoco rivers. In 2003 and 2004, we determined the density, biomass and size frequency distribution of oyster populations on the reefs during spring, summer and fall. Recruitment of oysters to the reefs was quantified using standardized substrates deployed and retrieved from the reef surfaces on a weekly or bi-weekly schedule from May through November. The prevalence and intensity of the oyster pathogens Perkinsus marinus and Haplosporidium nelsoni in oysters on the reefs was determined from samples taken in October 2004 and compared with values taken from another study on the reefs in October 2003. Additionally, the composition and abundance of other epifaunal community constituents associated each of the reefs were enumerated. We characterized the condition of reef base material by measuring the prevalence of present or past damage by boring sponge (Cliona spp.) and by measuring individual particle sizes. Finally, large-scale reef attributes such as slope and water depth were quantified. Oyster population data were then related to epifaunal community metrics and substrate condition with correlation analyses.
