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.

This book was released on 2012 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Artificial beach nourishment, the most common method to mitigate coastal erosion in the United States, is also considered the most ecologically friendly alternative for shoreline stabilization. However, this habitat alteration has the potential to impact nesting marine turtles and developing hatchlings. The first objective of this study was to determine how nourishing beaches with two different design templates affects loggerhead (Caretta caretta) and green turtle (Chelonia mydas) nesting success, the ratio of nests to the total number of nests and non-nesting emergences, and reproductive success, the ratio of hatched and emerged hatchlings to the total number of eggs deposited. Two types of restoration designs exist along the southern Brevard County, FL coastline, which supports some of the highest density loggerhead and green turtle nesting worldwide. Since 2005, approximately 35 kilometers of beach have undergone 1) full-scale restoration (typically called nourishment), where sand was added above and below the mean high tide line (2005, 2010) or 2) dune restoration, where sand was placed on the dune (2005, 2006, 2008, 2009). To quantify the effects of these restoration types, we used a Before-After-Control-Impact-Paired Series (BACIPS) model, which tests for significance between the difference in nesting success rates at the impact (engineered) and control sites (natural beach) before and after restoration ([delta]). For loggerheads, there was a significant difference in [delta] after dune restoration during the years of construction (2005, 2006, 2008, and 2009; p[less than]0.001) and one year post-construction (2007; p[less than]0.05 and 2010; p[less than]0.001). After full-scale restoration, there was a significant difference in [delta] during the years of construction (2005 and 2010; p [less than]0.001) and one year post-construction (2006; p[less than]0.001). For green turtles, there was a significant difference in[delta] after dune restoration during two of the four years of construction (2006; p[less than]0.05 and 2008; p[less than]0.01) and one of the two one-year post-construction years (2010; p[less than]0.05). After full-scale restoration, the significant difference in [delta] lasted every season (2005-2010; p[less than]0.001). There were no significant differences in [delta] for loggerhead or green turtle reproductive success rates after either type of restoration. The second objective was to use the different restoration designs to study what beach characteristics function as loggerhead nesting cues to explain why altering the beach decreases nesting success rates. We examined beach elevation and slope, sand moisture content, sand grain size, beach width, and distance traveled. Logistic regression model selection found all variables were important (R2=0.75). Further examination of trends, with each crawl divided into quarters, found beach slope served as a nesting cue. In all study sites except one, when turtles false crawled, the beach flattened out in the final quarter of the crawl. Conversely, in nesting emergences, the final quarter rose at a steeper slope than the previous quarter. Additionally, model selection found variables important in nest site selection were also important in hatching (R2=0.44) and emergence (R2=0.45) success. These results offer new insight into how and why marine turtle nesting patterns change after artificial nourishment, providing information necessary to nourish beaches in a more "turtle-friendly" manner.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Loggerhead sea turtles (Caretta caretta) are currently listed as "vulnerable" on the IUCN Red List and are experiencing population declines across many parts of their range. These declines are caused by environmental and anthropogenic stressors which impact sea turtle ecology and behavior, including nesting behavior. One nesting behavior sea turtles exhibit is known as "false crawling," which is when a female sea turtle ascends the beach in an attempt to nest and either abandons the attempt altogether or while in the middle of digging an egg chamber. False crawling, a largely understudied sea turtle behavior, can not only be detrimental to the reproductive output of an individual female but could negatively impact an entire population's reproductive success if the behavior is widespread. To investigate the different environmental and anthropogenic factors that may affect false crawling behavior in loggerheads we used historical survey data to determine the impact of a large anthropogenic structure (revetment) on a loggerhead nesting beach on Jekyll Island, GA. We then conducted surveys of the same beach for two years to assess the effects of lighting pollution, sand surface temperature, sand subsurface temperature, human presence, anthropogenic obstructions, and marine debris. For the 2008 - 2019 nesting seasons, we found that loggerhead false crawling rates were significantly higher near the revetment than on other parts of the beach, and that loggerheads mostly avoided trying to nest near the revetment at all. For the 2020 and 2021 nesting seasons, we found that sand subsurface temperature, human presence, and location relative to the revetment each significantly affected loggerhead false crawl rates, though sometimes in surprising ways. Overall, these results suggest that on Jekyll Island false crawling by loggerheads has been primarily caused by the presence of a large anthropogenic obstruction, but that other factors can also affect false crawling in context-specific ways.
