This book was released on 2020 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Eelgrass (Zostera marina) supports diverse and productive ecosystems in the coastal zone, and is at threat from a variety of human activities. Warming seawater temperatures, changing storm patterns, and altered dynamics of freshwater and nutrient run-off associated with climate change have already impacted eelgrass communities worldwide, and are expected to continue to do so into the future. In this report we characterize the physical environment at 10 eelgrass sites along the Atlantic Coast of Nova Scotia to provide a documentation of the range of environmental conditions under which eelgrass occurs in this region, and set the stage for the development of empirical relationships between physical conditions and eelgrass ecosystem status"--Abstract, page iv.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Nearshore marine construction activities often involve projects conducted directly in or adjacent to eelgrass beds and can have detrimental effects on eelgrass health, through physical destruction of beds, smothering of plants by sediment, and light reduction from turbidity. A liquefied natural gas (LNG) marine terminal is proposed to be constructed near Goldboro in Isaacs Harbour on the Eastern shore of Nova Scotia in an area where sediments are contaminated with heavy metals from historical goldmining operations. We conducted a pre-impact assessment of the eelgrass beds in Isaacs Harbour and in adjacent contaminated and non-contaminated harbours. We used underwater video to precisely map the eelgrass bed in the direct construction footprint in Isaacs Harbour and to identify eelgrass presence or absence in the nearby region. The overall condition of eelgrass plants in the surveyed area fell within the range of healthy plant characteristics (morphometrics and carbohydrates reserves) seen elsewhere along the Atlantic coast. However, a few stations displayed high arsenic and mercury contamination in sediments, which translated in some cases to high contamination in eelgrass rhizomes and leaves. There would be significant risk of impact on benthic habitat and contamination of marine biota from resuspension of sediments during a construction and operation of a ship terminal in Isaacs Harbour. This pre-impact assessment will allow DFO to assess the LNG terminal construction proposal and develop appropriate mitigation and monitoring procedures. Collected data will also be used for habitat-forming species distribution modeling to inform marine spatial and conservation planning"--Abstract, page iv.

Download or read book Environmental Risk Assessment and Management from a Landscape Perspective written by Lawrence A. Kapustka and published by John Wiley & Sons. This book was released on 2010-07-15 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: An important guide to assessing and managing the environment from a landscape perspective Ecological relationships are nested within the landscape. Identifying the relevant spatial and temporal scales is critical for an effective understanding of ecological functions that human societies depend upon. Moreover, human encroachment into natural areas, or changes in climate, can alter spatial relationships, which in turn can negatively affect vital plant and wildlife patterns—and weaken economic structures needed to sustain human societies. This book is the first to combine multiple disciplines into one cohesive strategy to study these crucial connections, and looks toward building a social paradigm that embraces the dynamics of ecological systems. This book: Integrates landscape ecology, environmental risk assessment, valuation of ecological goods and services, and environmental management decision processes into one single source Includes chapters on quantitative measures, Bayesian modeling,¿economic analysis, and sustainable landscapes Covers marine, forest, agricultural, and pharmaceutical risk assessment Has a chapter on predicting climate change risk to ecosystems Has a companion ftp site with color graphics, animations, and risk assessment tools With material that is accessible across all knowledge levels, Environmental Risk Assessment and Management from a Landscape Perspective moves beyond looking solely at chemical contaminants to diagnose environmental threats, and aims to accomplish practical risk assessment in a manner that supports long-term sustainable management.

Download or read book Seedling Ecology and Evolution written by Mary Allessio Leck and published by Cambridge University Press. This book was released on 2008-09-18 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seedlings are highly sensitive to their environment. After seeds, they typically suffer the highest mortality of any life history stage. This book provides a comprehensive exploration of the seedling stage of the plant life cycle. It considers the importance of seedlings in plant communities; environmental factors with special impact on seedlings; the morphological and physiological diversity of seedlings including mycorrhizae; the relationship of the seedling with other life stages; seedling evolution; and seedlings in human altered ecosystems, including deserts, tropical rainforests, and habitat restoration projects. The diversity of seedlings is portrayed by including specialised groups like orchids, bromeliads, and parasitic and carnivorous plants. Discussions of physiology, morphology, evolution and ecology are brought together to focus on how and why seedlings are successful. This important text sets the stage for future research and is valuable to graduate students and researchers in plant ecology, botany, agriculture and conservation.

Download or read book Relationships Between Juvenile Fish Assemblages and the Physical Features of Bays Along the Atlantic Coast of Mainland Nova Scotia with Implications for Coastal Marine Protected Areas written by Shannon Elizabeth O'Connor and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine Protected Area (MPA) sites are traditionally selected to protect individual species, or areas with scenic views. Selecting sites in an ecologically defensible manner reduces the arbitrariness in these decisions, and allows representative and distinctive areas to be identified and included in MPA networks. To further coastal conservation planning, this study examined coastal fish assemblages and the physical features of nearshore ecosystems to determine relationships between geophysical characteristics and biotic communities. Twenty bays were sampled for juvenile fish along the coast of mainland Nova Scotia, from Chedabucto Bay to the Bay of Fundy. Using a beach seine, 19,505 individual fish, representing 35 unique species, were caught during two field seasons (June - October 2005, June - September 2006). Based on physiographic features and environmental variables, bays sorted into well-defined bay types. Results indicated that the fish assemblages did not relate to these bay types, nor to geographic location. There were significant correlations between fish species and substrate type, in particular sediment particle size. Species-accumulation relationships discovered that a set of small bays, equal in shoreline length to a large bay, contained more fish species (26-35) than the larger bays (14-17 species). A minimum shoreline length of 3.37 km is required within a small bay to encompass all 35 species caught in this study. This study lays the foundation for the environmentally justifiable selection of representative coastal zone MPAs along the Atlantic coast of Nova Scotia.
