Book Synopsis Stressors in the Marine Environment by : Martin Solan
Download or read book Stressors in the Marine Environment written by Martin Solan and published by Oxford University Press. This book was released on 2016-03-10 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: A multitude of direct and indirect human influences have significantly altered the environmental conditions, composition, and diversity of marine communities. However, understanding and predicting the combined impacts of single and multiple stressors is particularly challenging because observed ecological feedbacks are underpinned by a number of physiological and behavioural responses that reflect stressor type, severity, and timing. Furthermore, integration between the traditional domains of physiology and ecology tends to be fragmented and focused towards the effects of a specific stressor or set of circumstances. This novel volume summarises the latest research in the physiological and ecological responses of marine species to a comprehensive range of marine stressors, including chemical and noise pollution, ocean acidification, hypoxia, UV radiation, thermal and salinity stress before providing a perspective on future outcomes for some of the most pressing environmental issues facing society today. Stressors in the Marine Environment synthesises the combined expertise of a range of international researchers, providing a truly interdisciplinary and accessible summary of the field. It is essential reading for graduate students as well as professional researchers in environmental physiology, ecology, marine biology, conservation biology, and marine resource management. It will also be of particular relevance and use to the regulatory agencies and authorities tasked with managing the marine environment, including social scientists and environmental economists.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although salt marshes cover only a small area of the Earth, their contribution to long term carbon (C) burial is comparable to C sinks in many more dominant terrestrial ecosystem types. Continuous nitrogen (N) loading alters plant growth and subsequently has the potential to impact soil organic carbon (SOC) accumulation in salt marshes. However, there is presently little information concerning the input and allocation of photosynthesized C in plant-soil-microbial systems. This knowledge gap hampers the quantification of C fluxes and the clarification of the mechanisms controlling the C budget under N loading in salt marsh ecosystems. To address this, we conducted an N fertilization field observation combined with a five hour 13C-pulse labeling experiment in a salt marsh dominated by Suaeda. salsa (S. salsa) in the Yellow River Delta, China. N fertilization increased net 13C assimilation of S. Salsa by 177.37%, which was primarily allocated to aboveground biomass and SOC. However, N fertilization had little effect on 13C allocation to belowground biomass. Correlation analysis showed that 13C incorporation in soil was significantly and linearly correlated with 13C incorporation in shoots rather than in roots both in a 0N (0 g N m-2 yr-1) and +N (20 g N m-2 yr-1) group. The results suggest that SOC increase under N fertilization was mainly due to an increased C assimilation rate and more efficient downward transfer of photosynthesized C instead of root lysate and detritus. In addition, N fertilization strongly improved the 13C amounts in the chloroform-labile SOC component by 315%. However, the absolute increment of newly fix 13C mainly existed in the form of residual SOC, which had more tendency for burial in the soil. Thus, N fertilization enhanced SOC accumulation although C loss increased via belowground respiration. These results have important implications for predicting the carbon budget under further human-induced N loading.

This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Replanting of intertidal salt marshes with native plant species has been used as an oil spill restoration tactic. These replanting restoration projects attempt to re-establish marsh function and inhibit erosion. Nutrient enrichment may be an option when restoring salt marsh ecosystems but there is conflicting evidence amendment provides an increase in belowground biomass to help stabilize the marsh and prevent erosion. The purpose of this study to determine the level at which marine fuel oil will have an adverse effect on Spartina alterniflora and Spartina patens and to measure the stem growth and root production of S. alterniflora in response to fertilizer treatment. Spartina sp. plugs were treated with five different oil slick thicknesses ranging from 0μm to 3000μm in a greenhouse. After 28-d, the plant stem height, stem density, and aboveground and below ground biomass were recorded. Overall, there was no significant effect of oil on plant performance for both grass species. There was no significant difference in stem density and stem height 140 d after removing the standing oiled stem. S. alterniflora seedlings were treated with OsmocoteTM smart-release fertilizer (“high” and “low” treatments) along with a control. Endpoints included stem density, stem height, aboveground and belowground biomass, root and rhizome length, and root and rhizome diameter. The “high” fertilizer treatment was determined to increase stem density and stem height. There was no significant effect of fertilizer on root or rhizome production. This study focused on plant growth and physiology however, the implications of oil on salt marsh ecosystems at a community and ecosystem level still warrant additional monitoring and research to better understand these interactions.

Book Synopsis Aspects of Carbon and Nitrogen Cycling in a Spartina Dominated Salt Marsh on the Northumberland Strait, Nova Scotia : and the Effects of Impoundment by : Hatcher, Annamarie Irene
Download or read book Aspects of Carbon and Nitrogen Cycling in a Spartina Dominated Salt Marsh on the Northumberland Strait, Nova Scotia : and the Effects of Impoundment written by Hatcher, Annamarie Irene and published by 1977 [c1978]. This book was released on 1977 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annual pure stand above ground production of the three dominant macrophytes in a salt marsh on the Northumberland Strait, Nova Scotia was 317. gms. c/m2 for Spartina alterniflora, and 152. gms. c/m2 for Spartina patens, measured at peak biomass; and 56.3 gms. c/m2 for Zostera marina, measured in December, before winter ice cover. Total organic carbon loss, monitored in the tides, combined with estimates of winter carbon losses through decomposition and ice scour of S.alterniflora and S. patens yielded an annual export figure of 80. gmc.c/m2/yr., approximately 50% of the area weighted mean macrophyte production. Nitrogen input to the study area through nitrogen fixation on the soil surface and within the rhizospheres of S. alterniflora and S. patens is of similar magnitude to nitrogen imported by tidal waters in the forms of ammonia, nitrate and nitrite. The enclosure of 34 ha. of the Wallace Bay salt marsh with a constant flooding regime was completed in September, 1974 to encourage.
