Book The Effects of Salinity Depth and Turbidity on Submerged Aquatic Vegetation SAV Abundance in Eastern North Carolina

Download or read book The Effects of Salinity Depth and Turbidity on Submerged Aquatic Vegetation SAV Abundance in Eastern North Carolina written by Noah Scott Gwynn and published by . This book was released on 2021 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: The state of North Carolina is concerned about the loss of submerged aquatic vegetation (SAV), which is critical fish and wildlife habitat in low-salinity estuaries. Sentinel sites have been established by the East Carolina University/Albemarle Pamlico National Estuarine Partnership (APNEP) SAV monitoring team at locations where SAV has been observed in historical surveys. Using monitoring data collected from low-salinity sentinel site locations in the Neuse River Estuary (NRE), Pamlico River Estuary (PRE), and Albemarle Sound (AS) from 2015 to 2019, I evaluated the effects of turbidity (measured by Secchi depth), salinity and water depth on SAV abundance (odds of occurrence, percent cover, percent frequency, and dry biomass). The maximum colonization depth of SAV was also analyzed. My goal was to understand what physical factors impact low-salinity SAV survival and growth in North Carolina estuaries by focusing on the three dominant species found (Ruppia maritima, Vallisneria americana, and Zannichellia palustris). Data came from inshore quadrat diver surveys that measured percent cover using 1 m2 quadrats at depths of 0.25, 0.5, 0.75, and 1 m. Dry biomass abundance was determined by taking core samples along sampling transects. An ensemble data set from North Carolina Department of Environmental Quality (NCDEQ), Modmon, and North Carolina Department of Marine Fisheries (NCDMF) data bases) was used to create inverse distance weighted prediction models of Secchi depth and salinity for use in analysis of maximum colonization depth of SAV. SONAR methods included the use of Lowrance single beam 200khz echosounder to measure maximum colonization depth of SAV along 40 transects per sentinel site. Some sentinel sites were omitted from the analyses because they contained no SAV during the monitoring period. I observed that water transparency also called turbidity in this thesis (measured by Secchi depth), salinity, and water depth had significant effects on dominant SAV species with the direction of the association being species dependent. Ruppia maritima odds of occurrence increased with salinity, water depth, and turbidity. Vallisneria americana odds of occurrence showed a negative association with turbidity and salinity but a positive correlation with water depth out to 1 m. Zannichellia palustris odds of occurrence showed no significant effect with turbidity and salinity but was significantly associated with increased water depth. Differences in SAV species salinity and water transparency responses suggest these two factors contribute significantly to the distribution of dominant SAV species. Maximum colonization depth of SAV is greater in sentinel sites with higher Secchi depths, especially when a long-term average Secchi depth is used (ensemble data set). Ruppia maritima has been predicted by my logistic regression model and field observations to be favored in the competition among North Carolina SAV species.

Book Biogeographic Characterization of Fishes from Intertidal Sandflats in Pamlico River North Carolina

Download or read book Biogeographic Characterization of Fishes from Intertidal Sandflats in Pamlico River North Carolina written by M. Wayne Mabe and published by . This book was released on 2012 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: The spatial and temporal changes in fish community structure in Pamlico River, North Carolina were analyzed. Salinity and temperature are important water quality parameters influencing fish community structure in estuaries. Fish were collected with an 18 m long bag seine from sandy habitats in Pamlico River, North Carolina. Each station was sampled bi-monthly (August to November) in 2009-2010. The North Carolina Division of Marine Fisheries (NCDMF) Program 123 has been collecting fish from two stations in Pamlico River since 1987. There are two main differences between this study and Program 123. First, Program 123 has a much narrower geographic sampling area than this study. I sampled 18 fixed locations from Washington, North Carolina to the mouth of Pamlico Sound; whereas, NCDMF sampled only two stations near Bath, North Carolina. Second, sampling frequency was higher in this study than in Program 123. I sampled bi-weekly in October and November, 2009 and August to November, 2010; whereas, Program 123 sampled monthly from September to November, 2009 and 2010. Analysis of similarity (ANOSIM), non-metric multidimensional scaling (MDS), and canonical correspondence analysis (CCA) were used to test for differences in fish community structure both spatially and temporally, in Pamlico River, and to test for the correlation of water quality to fish community structure. Analysis of variance (ANOVA) was used to test for significance in water quality among the various sections. Five species (Anchoa mitchilli, Menidia beryllina, Brevoortia tyrannus, Leiostomus xanthurus, and Lagodon rhomboides) accounted for 97.4% of the total abundance in Pamlico River. Temporal and spatial changes in fish community structure were important in Pamlico River. Temperature was the most important environmental factor correlating with temporal fish community structure in Pamlico River. Salinity was the most important factor in spatial fish community structure. Program 123 captured greater catch per unit effort (CPUE) than this study because Program 123 only sampled the Central section, where greatest fish abundance occurred. However, greater species diversity was captured in this study than in Program 123.
