Annotation:
Traditional techniques for studying green turtle foraging ecology, such as the analysis of food availability and ingested dietary material, have concluded that green turtles are primarily herbivorous but selective foragers. However, green turtles that forage during Lyngbya majuscula blooms are exposed to toxins produced by the cyanobacterium overgrowing the seagrass. We used the Crittercam, an animal-borne imaging device, to observe green turtle foraging behavior in Moreton Bay, Australia, and to evaluate the system for assessing the impacts of Lyngbya blooms on green turtles. Eight large green turtles were captured while foraging on seagrass flats and each was fitted with a Crittercam. The deployments yielded over 28 hours of video and associated time-depth records. Turtles swam almost continuously and rarely stopped to feed on seagrass. Six turtles were observed feeding and all six consumed gelatinous animals from the water column. This prey source was previously undocumented in the Moreton Bay green turtle population but described in other green turtle populations using the Crittercam. Only one turtle was observed foraging on seagrass. The results of this study indicate that Crittercam technology can provide insight into turtle diet selection and that it will be a useful tool in identifying the impacts of Lyngbya blooms on green turtle feeding ecology. This study has also demonstrated that turtles in Moreton Bay may have a more flexible diet than previously described, indicating they could potentially supplement their diet with alternate prey items when seagrass quality or quantity is compromised. Longer deployment times, with an initial acclimation phase, are required to more fully understand questions pertaining to feeding ecology.

First reports of green turtles Chelonia mydas with fibropapillomas, in Yucatán, México Fibropapillomas are cutaneous tumors that affect the health of marine turtles worldwide. In July 11th of 1998, a juvenile green turtle (Chelonia mydas) with tumors was captured by fishermen in the Sea Turtles Sanctuary of Rio Lagartos, Yucatán. The straight carapace length of this turtle was 44.6 cm, and we found 30 tumors with a size from 1 cm - 10 cm on the back flippers, neck, front flippers and in both eyes. On July 10th, 1999, another juvenile green turtle with fibropapillomatosis was captured by fishermen in the same area. This turtle was smaller (S.C.L. = 40.8 cm) with 5 small tumors (1 cm - 4 cm) on the back flippers and tail. The prevalence of fibro papillomatosis in Yucatan is low (2.4%). Considering the migratory route of this species and the high prevalence of green turtles with fibropapillomas in Florida, USA, we suggest an initial contagion between the populations of these peninsulas. Those are the first documented reports of green turtles with fibropapillomas in Yucatán, México.

Annotation:
Green turtles Chelonia mydas occur sporadically in tropical and subtropical latitudes, but effective conservation efforts are leading to increasing abundances at higher latitudes. One consequence of increased green turtle abundance in some locations has been the overgrazing of seagrasses, their preferred food item. Recent, large increases in juvenile green turtle abundance in the warm temperate northern Gulf of Mexico, especially in the clear waters of St Joseph Bay, FL, make this a prime location to study effects of their feeding activities on the extensive turtlegrass Thalassia testudinum-dominated meadows. Using caging and simulated grazing to quantify green turtle effects, we found that excluding green turtles led to increased Thalassia shoot density, and that simulating turtle grazing resulted in narrowed leaves and decreased turtlegrass productivity. Naturally grazed areas protected from further turtle grazing did not recover after 14 wk of protection. Two years following relaxation of simulated grazing, turtlegrass continued to show residual stress symptoms, with narrower and fewer leaves per shoot than control areas. The future success of sea turtle conservation efforts is critically linked, and dependent on, the protection and sustainability of globally decreasing sea turtle feeding grounds. Thus, continued study of how increasing green turtle populations affect warm temperate turtlegrass meadows will provide important information on how best to manage both turtle and seagrass resources.

Annotation:
The sex of the turtles is determined by the incubation temperature of the eggs during the mid-trimester of development. In green sea turtles (Chelonia mydas), recent studies show that sex ratios are changing, producing a female-biased sex ratio within the population. We developed a novel continuous model to analyze the dynamics of the green sea turtle population long-term. We determine the safe operating space for the proportion of eggs that become male at which the population of green sea turtle can exist without going to extinction. When the proportion of male eggs leaves this range the overall turtles’ population collapses. Additionally, we examined how temperature changes affect the sex ratios of the green sea turtle population.

Annotation:
Of the six species of marine turtle in Papua New Guinea, the green turtle Chelonia mydas and the hawksbill turtle Eretmochelys imbricata are the most common and the most utilized in the Port Moresby region. This paper describes a study carried out in 1989, which monitored the trade in green turtles in the country's main market and the sale of tortoiseshell in a major shopping centre. The price of turtle meat was higher than that of some common reef fish, but cost less when fish was abundant. The commercial trade in tortoiseshell appeared to be negligible. As the urban population increases it is likely that demand for turtle meat will also increase. If this food resource is to be managed sustainably the size of the turtle population needs to be determined. The University of Papua New Guinea is supporting marine turtle field studies and a sea turtle education programme, but more needs to be done to ensure the survival of PNG's marine turtles.

Annotation:
A total of 209 strandings of sea turtles (152 loggerhead turtles Caretta caretta, 42 green turtles Chelonia mydas, 15 unidentified) were recorded during the period 1984–2011 along the coasts of Rhodes (Aegean Sea, Greece). The proportion of dead to live individuals was different in the two species. Stranded Caretta caretta were larger than Chelonia mydas. The size range of stranded green turtles, usually juveniles, appeared to increase since 2000, including the largest specimens ever observed in Greek waters. For both species, a tendency to strand more frequently on the west coast of the island, along fishing ground areas, was noted. The higher incidence of loggerhead turtle strandings was observed in summer, while more green turtle strandings were documented in winter. Factors involved in the increased trend of stranding records of both species, along with the acceleration of this phenomenon in the last decade, are discussed. Data from Rhodes provide evidence that human activities detrimentally affect mainly larger-sized loggerhead turtles living in shallow waters.

AbstractGlobal marine turtle population assessments highlight the importance of the south-west Indian Ocean region, despite data gaps for the Chagos Archipelago. The archipelago hosts nesting hawksbill Eretmochelys imbricata and green turtles Chelonia mydas, both heavily exploited for 2 centuries until protection in 1968–1970. We assessed available nesting habitat and spatial distribution of nesting activity during rapid surveys of 90% of the archipelago's coastline in 1996, 1999, 2006 and 2016. We quantified seasonality and mean annual egg clutch production from monthly track counts during 2006–2018 along a 2.8 km index beach on Diego Garcia island. An estimated 56% (132 km) of coastline provided suitable nesting habitat. Diego Garcia and Peros Banhos atolls accounted for 90.4% of hawksbill and 70.4% of green turtle nesting. Hawksbill turtles showed distinct nesting peaks during October–February, and green turtles nested year-round with elevated activity during June–October. Estimates of 6,300 hawksbill and 20,500 green turtle clutches laid annually during 2011–2018 indicate that nesting on the Chagos Archipelago has increased 2–5 times for hawksbill turtles and 4–9 times for green turtles since 1996. Regional estimates indicate green turtles produce 10 times more egg clutches than hawksbill turtles, and the Chagos Archipelago accounts for 39–51% of an estimated 12,500–16,000 hawksbill and 14–20% of an estimated 104,000–143,500 green turtle clutches laid in the south-west Indian Ocean. The improved status may reflect > 40 years without significant exploitation. Long-term monitoring is needed to captureinterannual variation in nesting numbers and minimize uncertainty in population estimates.

AbstractThe status of marine turtles in Angola, West Africa, is poorly known, and therefore during 2000–2006 a combination of both dedicated and opportunistic beach and at-sea turtle surveys were carried out, and interviews conducted with fishing communities and at markets. Green Chelonia mydas, olive ridley Lepidochelys olivacea, leatherback Dermochelys coriacea and loggerhead turtles Caretta caretta were recorded, and nesting of the first three species confirmed during September–March (peaking November–December). Green turtles nested mainly in the south, leatherback turtles in north and central Angola, and olive ridley turtle nesting was widespread. Olive ridley turtle nest density at Palmeirinhas averaged 32 nests km−1. At-sea surveys produced 298 turtle records, with peak occurrence during August. Significant anthropogenic-related mortality (including exploitation of meat and eggs and fishing bycatch) was recorded, in addition to natural predation and other threats. Maintenance of the long-term sustainability of these turtle populations should focus on the involvement of fishing communities and increasing awareness throughout Angola.

Five species of sea turtles are known from Madagascar's coastal waters. Fishermen on the western and south-western coasts take green turtle Chelonia mydas, loggerhead turtle Caretta caretta and olive ridley Lepidochelys olivacea for their meat. The hawksbill turtle Eretmochelys imbricata is taken mainly for its shell and for making stuffed specimens while the leatherback Dermochelys coriacea is seldom caught. Anecdotal evidence of fishermen and dealers in turtle products, measurement of captured animals and personal observations of the authors all point to declines in numbers and average size for green and hawksbill turtles, coupled with marked declines in nesting rates for these and the olive ridley.

Annotation:
Resource subsidies are flows of nutrients from one ecosystem to another. Sandy beach ecosystems are at the interface between land and sea and thus receive nutrients from both land/seascapes. The seasonal nesting of sea turtles introduces large inputs of eggs, and so nutrients, onto sandy beach ecosystems, but little is known about the effects of these spatially and temporally variable nutrient input pulses on the dynamics of consumers in the recipient system. In this study, I examined the ecological role of sea turtles as vectors of nutrients that introduce large amounts of nutrients (in the form of eggs) from distant foraging grounds into nutrient-poor beach ecosystems. Although some of the nutrients return to the sea in the form of hatchlings, nutrients from unhatched and depredated eggs, dead and predated hatchlings, as well as chorioallantoic fluid and egg shells remain on the beach and presumably enter sandy beach food webs. I hypothesized that turtle nutrients significantly increase the availability of nutrients to sandy beach ecosystems and that those nutrients are incorporated by both terrestrial and marine food webs. These hypotheses were tested by comparing isotopic signatures of 13C and 15N of consumers on beaches with high and low turtle nest densities. The response of meiofauna to the decomposition of turtle eggs was also investigated. I predicted that meiofaunal abundance is positively affected by turtle nutrients and that higher meiofaunal abundances will be obtained in decomposing, depredated nests. I tested this hypothesis by comparing meiofaunal abundance in naturally predated nests to densities away from turtle nests (as a control). An in situ experiment that mimics conditions of naturally predated sea turtle nest, was set up to test meiofaunal community responses to turtle nutrients over time. The study indicates that sea turtle eggs represent a short pulsed resource subsidy that increases the nutrient and energy budget of sandy beach ecosystems. The results show that of the five potential nutrient pathways tested, ghost crabs appear to consume egg nutrients in measurable quantities, altering their diet and feeding behaviour according to food availability. The study also showed that there was a strong, but short-lived positive response of meiofauna to the introduction of nutrients, with increased abundance of all taxa in predated nests and experimental treatments. This response was particularly strong for nematodes which peaked in abundance after seven days. I conclude that turtle-derived nutrients represent a pulsed resource subsidy that makes significant contribution to the energy budget of sandy beach/dune ecosystems.

In oviparous animals, maternal traits such as the investment of resources in eggs and oviposition site selection are often important determinants of offspring phenotypic quality, and may have an adaptive role in tailoring offspring phenotypes to local environmental conditions. This thesis examines the adaptive significance of two specific maternal traits in the green turtle (Chelonia mydas); namely the deposition of fat-soluble antioxidants in egg yolk, and the selection of nest sites via natal homing.

Annotation:
The hierarchical levels at which resource selection occurs can have important consequences for individual and population energy budgets and structure the impacts of a forager on its ecosystem. Assessing factors affecting resource selection of large marine herbivores across scales is important because of their potentially large impacts on seagrass community dynamics and historical and current changes in their population sizes and those of their potential predators. I explored the factors (predation risk, resource abundance, quality and identity) affecting resource use of large marine herbivores (green turtles, Chelonia mydas) from the scale of habitat patches to forage species within patches. I used a combination of in-water surveys, aerial drone video transects, baited camera surveys, and seagrass community and nutrient content analyses to provide insights into resource use by turtles in multiple ecological contexts. In Abaco, The Bahamas I found relatively intact shark populations, including apex predators, relative to other parts of the Caribbean. In the context of healthy predator populations in Abaco, I tested a priori predictions rooted in Ideal Free Distribution (IFD) theory. Green turtles off Abaco deviated from predictions of an IFD determined by the standing stocks of seagrass. Instead, distributions are consistent with predictions of the foraging arena hypothesis with turtles largely restricted to safe habitat patches and selecting locations within these where seagrass N content is relatively high. Marine invasive species can have detrimental effects on coastal ecosystems and economies. Therefore, understanding the effects of, and factors influencing the rate of spread of the invasive seagrass Halophila stipulacea in the Caribbean is important. In the French West Indies (Guadeloupe, Martinique and St. Martin), I investigated foraging preferences for native versus invasive seagrass species and whether green turtles might facilitate or attenuate the invasion through their choice of habitats and feeding patterns. Green turtle distributions were correlated with native seagrass distributions. Also, despite similar nutrient contents, turtles preferred feeding on native seagrasses irrespective of their relative abundance within a patch. These results suggest that, as predicted by the Enemy Release Hypothesis, green turtles likely facilitate the invasion and spread of the invasive seagrass that may reduce energy flow into turtle populations.

The design of effective species management and recovery plans for sea turtle populations requires targets that are informed by an understanding of knowledge gained at the level of individuals/populations in the context of the wider goal of protecting an ecosystem's structural and functional attributes. In this thesis I present the first detailed investigation of the multiple levels at which sea turtles, particularly green turtles (Chelonia mydas), interact with ecosystems. I begin by developing a framework for an age-structured population-level assessment of food consumption for hawksbill (Eretmochelys imbricata), loggerhead (Caretta caretta), and green turtles. This entailed construction of species-specific growth models for the western Atlantic, and subsequent integration of results with morphometric, survival, abundance, and food conversion efficiency to derive consumption estimates. At the ecosystem level, I developed models for the Caribbean and Hawai’í, where green turtles are present at very low abundances and reaching carrying capacity, respectively. In the Caribbean, results showed that green turtle grazing of seagrass substantially altered habitat complexity, reducing the refuge role of seagrass to reef fish and invertebrates, and leading to potentially dramatic changes in species biomass and composition. In Hawai‘i, by feeding on algae, green turtles were found to contribute to the resilience of reefs in the face of disturbance, a functional role that needs to be explicitly included in future studies of reef dynamics. Taken together, these findings highlight the need to consider trophic and indirect interactions in the evaluation of sea turtles’ role within ecosystems. Accurate and reliable estimates of foraging habitat extent are essential to inform realistic and sustainable turtle recovery targets, particularly given the current degraded state of coastal ecosystems. Using Landsat satellite imagery, I present a novel mapping approach for seagrass habitats at large scales. Such regional initiatives are also urgently needed if the international community is to meet aims to conserve 10 – 30 % of specific habitats. A comparison between reef extent, determined using remote sensing and existing data, showed that discrepancies ranged from + 1,316 % to - 64 %, underlining our limited ability to ascertain progress towards adopted global marine conservation targets based on current data.

Annotation:
Behavioral studies in the green turtle (Chelonia mydas) have indicated that promiscuous mating is commonplace. Though it has been shown that there is much variation in the rate of polyandry (females mating with multiple males), the drivers behind polyandry in this species are unknown. It has been speculated, but never demonstrated, that indirect benefits (fitness benefits resulting from offspring genetic diversity) play a role. However, previous tests of this hypothesis have limited scope of inference due to lack of environmental control. In this thesis, I attempted to study the indirect benefits of polyandry in Archie Carr National Wildlife Refuge (ACNWR) green turtles, limiting environmental variation by selecting nests over two week periods in a small subset of the ACNWR. Through the use of highly polymorphic microsatellite markers, I show that 85.7% of ACNWR green turtle females mate with multiple males, the highest rate yet reported for green turtles. I was successful in limiting environmental variation; however, I was unable to make comparisons among nests with one or multiple fathers because of a limited sample size of single father nests. Regardless, my thesis provides preliminary evidence (number of males per nest) that the density of males off Florida's beaches may be relatively high, which is expected to be a driver behind the evolution of polyandry and likely plays a large role both in this population and the prevalence of multiple paternity in green turtles as a whole.

Annotation:
Green turtle fibropapilloma (GTFP) is a debilitating and frequently fatal disease of green sea turtles. The etiological agent that causes this disease is unknown, however, recent evidence suggests that a novel green turtle herpesvirus (GTHV) is closely associated with GTFP. Because this virus has not been isolated or propagated in vitro cell culture to date, it is necessary to obtain more genomic information of GTHV in order to establish its pathogenic role in relation to GTFP. Using a modified genomic walking technique, based on inverse polymerase chain reaction (IPCR), a total of 9,032 base pair DNA sequences of the newfound GTHV was sequenced from tumor tissues of green turtles with fibropapillomas. This newly identified DNA fragment contains three potential pathogenic genes from the unique long (UL) region of GTHV: UL29 (DNA binding protein gene), UL28 (assembly protein gene) and UL27 (glycoprotein B gene). The UL29 gene was sequenced through 4 consecutive genomic walks in which a total viral fragment of 4,054 bp of sequence data was obtained. This viral DNA fragment contains the entire open reading frame of the UL29 gene (ORF), which is oriented in the 3' to 5' direction, and encodes the full-length genomic sequence of the DNA binding protein (DBP) gene (3,585 bp) corresponding to a protein of 1,195 amino acid residues. The viral fragment also encodes a partial sequence of the UL28 gene, which is oriented in the 3' to 5' direction as well. Through 2 subsequent genomic walks, the remainder of the UL28 was sequenced in its entirety, as well as a partial ORF of the UL27 gene. The UL28 gene has an ORF of 2,250 bp with a putative amino acid translation of 750 amino acids. Through 1 subsequent genomic walk the entire ORF of the UL27 gene was sequenced. This ORF is 2,551 bp long and overlaps the UL28 genome by 1 bp. The UL27 gene is oriented in the 3' to 5' direction and encodes the putative glycoprotein B (gB) transmembrane peptide, which is 851 amino acids in length. Phylogenetic analysis of GTHV DBP, UL28, and gB genes substantiated that this novel Chelonian herpesvirus is closely related to the Alphaherpesvirinae subfamily. Examination of the translated amino acid sequence further supports this categorization since GTHV DBP comprises a highly conserved zinc finger motif (CXLCX4RX2C) and a putative DNA binding domain, and exhibits high sequence homology to other alphaherpesviruses. The gB peptide also showed high homology to alphaherpesviruses in the extraviral, transmembrane and Cterminal tail regions of the peptide. Cloning and sequencing the genome of this putative herpesvirus will facilitate current understanding of its role in causing GTFP and the development of molecular- and immuno-based methods for the diagnosis and prevention of this devastating disease of green sea turtles.

Annotation:
<p>Modern civil engineering mega-projects dealing with buildings, bridges, and infrastructures take sustainable engineering into consideration for the development and execution of their proj-ects. Since sustainable development and sustainable engineering are rather broadly covered as global issues, each individual needs to take personal responsibility for environmental, social, and economic questions whose performance outcomes may impact the life cycle of the struc-ture. An integration concept on sustainable engineering will deal with emerging criteria and concept for a strategic approach to the planning, execution, operation, and maintenance phase of the building process. It can be shown that approaches to and strategies for these issues result from individual consciousness, national policies, and global actions. Current research has been conducted on the sustainability perspective of areas such as global climate changes, CO2 levels, life-cycle assessment (LCA), green design rating, emerging trends in sustainable engineering, and sustainability monitoring and evaluation criteria. However, there may still be more areas requiring further research to apply an integrated concept to emerging strategies for building a process to achieve the goals. Then the methods and procedures appropriate for each community or society can be explored. However, a quantifying performance method also needs to be used as a measure to guarantee satisfactory findings.</p>

Annotation:
This chapter draws on an array of sources including twentieth century scientific studies to offer insight into the habits and migratory patterns of sea turtles. As a result, the chapter discusses basic sea turtle biology differentiating the distinctive features of green and hawksbill turtles. It then explains how the two turtle varieties became global commodities for niche luxury markets. The chapter explains how indigenous and early New World newcomers—both European and non-European—came to adapt and learn how to hunt turtles in the Caribbean. It also traces the development of turtle hunting in the Cayman Islands. The chapter argues that turtles played a pivotal role in shaping these small islands and coastal societies as much as sugar or banana commodities did in other parts of the Caribbean.

Chapter one describes the parent groups of the Turtle Mountain Band – the Plains Ojibwe and the Métis – and the often cooperative, sometimes contentious nature of their relationship. Beginning in the early nineteenth century through mid-century, the chapter demonstrates the evolution of the Plains Ojibwe and Métis, their leadership and governance structures, and their overlap. While both groups had much in common and were often cooperative, there was tension and conflict as well. Both the Plains Ojibwe and Métis made claims to the land that would eventually come under dispute with the federal government.
