This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The analysis of the nesting data showed that approximately six of the nourishment events experienced declines in the first year or two post-nourishment, supporting the hypothesis. The remaining seven beaches did not support the hypothesis. Five of the nourishment events that did not support the hypothesis showed no difference in nesting densities compared to the control beaches, and the remaining two nourishment events experienced increases in nesting when compared to the control beach. The analysis of these 13 nourishment events indicates that the nesting sea turtles' responses to nourishment vary based on site-specific conditions. When data are available, nourishment projects should evaluate nesting trends following past nourishments at their particular beach to assist in developing an appropriate strategy for preventing declines in nesting. Due to the potential declines in sea turtle densities that may occur following nourishment, coastal managers should consider methods such as retreat to avoid the need for shoreline stabilization projects.

This book was released on 1987 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: A large percentage of all sea turtle nests in the United States are located in beaches that have been nourished or renourished. Questions have been raised about how physical changes in the beaches will affect the nesting activities of these sea turtles that use nourished beaches for nesting. Delray Beach had a harder consistency from both previous nourishments and the 1984 renourishment. The cause of the harder consistency is unclear. However, finer grain size, layering of sand grains, the cohesion of silt-clay particles, equipment operation on the beach, and weight of the sand-water slurry from the hydraulic pumping are probable contributors to a harder consistency. Effects of nourishment on nesting loggerhead turtles include: (1) eggs and hatchlings were not affected negatively by the nourished sand; (2) nest depth and frequency of false digs may be affected by the harder consistency, but this effect was not evident in this study; (3) nest shape and nest digging time may be affected by sand consistency; (4) the number of nests per emergence appears to have declined following the nourishment; (5) aragonite sand may negatively affect piping hatchlings; and (6) a scrap formed at Delray Beach and will form at most beaches. The scrap may block some turtles from nesting, while some may scale the scarp, particularly if the scarp is sloped.

This book was released on 1988 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to examine nest establishment and hatching success of nests of sea turtles in a compacted, nourished beach which has been tilled to decrease sand compaction. This study demonstrates the effectiveness of tilling at a full scale commercial level and the response of nesting turtles to the tilled beach.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: However, when the rates were analyzed by nesting season, the average hatching and emergence success rates were always lower on nourished beaches than on natural beaches. A hotspot analysis on nests and false crawls revealed that turtles preferred natural beaches that border nourished areas for nesting while false crawls were more evenly distributed through the study area. Although this study documents the negative effects of beach nourishment on loggerhead sea turtle nesting, nourishment projects are likely to continue because of their benefits to human populations. Further examining of the impacts that humans have on nesting and developing loggerheads will ultimately aid policy formation as we continue to manage and protect the future of the species.

Book excerpt: High sand compaction restricts gas diffusion between clutch and atmosphere. This accumulates carbon dioxide in the clutch and prevents oxygen from reaching the eggs. This combination of gases is detrimental to sea turtle development and leads to lower hatching and emerging successes. In the second experiment I found that high concentrations of unbound sand calcium carbonate reduced clutch carbon dioxide concentrations during the second half of incubation. This buffering effect maintained incubation gases within safe physiological levels and reduced clutch mortality. However, hatchlings emerging from these nests had significantly smaller body depths, higher packed cell volumes, higher total protein levels, and higher triglycerides. This physiological data indicate these hatchlings were more dehydrated and metabolized more yolk than controls. Their physiological condition worsened after crawling 10 meters, intended to replicate traversing the beach to ocean. Data show that although clutch carbon dioxide levels can be reduced by unbound sand calcium carbonate, high sand compaction has a consistently negative impact on diffusion of oxygen and carbon dioxide molecules. Differences in atmospheric concentrations, diffusion rates, and solubility of oxygen and carbon dioxide molecules, intensify this effect for the latter. Regulation of specific sand characteristics is paramount for beach nourishment projects. Engineers and regulators should incorporate the information emanating from this dissertation into future beach restoration projects because it relates human needs to the consequences beach sand can have on the incubation of loggerhead sea turtles.
