▼ ABSTRACT NATAL ORIGIN OF JUVENILE LOGGERHEAD TURTLES FROM FORAGING GROUND IN NICARAGUA AND PANAMA ESTIMATED USING MITOCHONDRIA DNA by ?? Akiko Masuda 2010 Master of Science in Biology California State University, Chico Summer 2010 The loggerhead turtle, Caretta caretta, is a long-lived, slowly maturing marine species, and is currently classified as globally endangered species by the International Union for Conservation of Nature and Natural Resources (IUCN2010). As with all seven marine turtle species, loggerheads have a complex life history including migrations spanning entire ocean basins. Shallow (neritic) waters close to the Caribbean coast of Nicaragua are used as foraging habitat by juvenile and adult loggerhead sea turtles (Caretta caretta), but the natal origin of these foraging turtles have not been yet determined. Loggerheads in Nicaragua are affected by intense artisanal and commercial fisheries requiring urgent conservation efforts. Our study is an estimation of the rookery origins of turtles in the loggerhead foraging aggregation in coastal waters of Nicaragua, and migratory connection among other foraging grounds throughout the Atlantic and Mediterranean. I obtained mtDNA D-loop sequences from 72 of 78 juvenile loggerhead turtle samples collected. I detected 18 haplotypes from the full 835 base-pair sequence and six haplotypes from 380 base-pair region used previous studies. Genetic diversity indicated that the Nicaragua foraging is a diverse mixed stock (h=0.61 n=0.0021). I applied a Bayesian hierarchal method of many-to-many multiple mixed stock analysis to estimate the origins and destinations of individuals in all available published nesting and foraging areas including our new foraging data. I also discuss that the possible influence of turtle body size, ocean circulation system, and oceanographic distance between nesting and foraging grounds, on loggerhead migration and recruitment patterns.

The purpose of this study was to determine the at-sea behavior of loggerhead turtles (Caretta caretta) in the Mediterranean Sea in order to gain a better understanding of the various environmental factors that play a role in their survival. By determining the environmental conditions that have a controlling force over foraging and nesting success, more accurate projections can be made on the future of this declining subpopulation of loggerheads. I deployed 20 satellite transmitters on postnesting adult loggerhead turtles from Rethymno, Crete, Greece, with 19 functioning through migration. Using a changepoint analysis model, I determined that loggerheads in the Mediterranean exhibited 5 behavior modes. Within these modes were migration, foraging and overwintering, along with newly discovered transition modes between each established sea turtle behavior. Overall, the turtles exhibited 3 unique postnesting strategies, 9 migrated to the North African coast, 6 migrated into the Aegean Sea and 4 remained within the waters of Crete. These three strategies corresponded to fitness differences between the turtles. The northern turtles were larger and had larger clutch sizes than those foraging near Crete and Africa. This corresponded to the abundance of prey from each region. The benthic environment of the Aegean had the largest prey abundance compared to the other sites. Around Crete there is very limited benthic environment to support loggerhead foraging, and in the Gulf of Gabes the prey abundances are reduced due to a high influx of industrial runoff. The Gulf of Gabes is home to ~40% of loggerheads nesting in Greece, and as global warming continues, the rising temperature is expected to exacerbate the deterioration of the benthic environment. Furthermore, there is already a strong female bias in sex ratio for Mediterranean loggerheads, which is expected to continue to get stronger as beach temperatures rise and precipitation declines. Loggerheads may be able to compensate for these changes, and I found that their nesting phenology is expected to shift earlier by as much as 52 - 74 days by 2100; however the factors threatening the survival of this species may be too strong to overcome.

▼ Historically, heavy metal research on sea turtles has been focused on deceased specimens, limiting the ability to determine if the concentrations of heavy metals affected the health of the individuals. More recently, the collection and analysis of blood samples from live turtles has enabled the researcher to investigate the potential health implications of observed metal concentrations. In this thesis, I present two original studies on the blood concentrations of essential and non-essential heavy metals and their potential physiological correlates on the endangered loggerhead sea turtle (Caretta caretta). This work reflects analysis of archived samples collected in 2008 off the southeastern coast of the United States by the South Carolina Department of Natural Resources (SCDNR). Research was funded in part by the Office of Protected Resources and NOAA Fisheries. Samples were obtained through the generous support of Rusty D. Day, MSc. The first study examined the relationships between body size, sex, geographic location, water depth, and blood concentration of 17 essential and non-essential heavy metals and metalloids. Statistical analysis of these parameters indicated that measures of body size were correlated with several of the metals, whereas sex had no significant relationship with any of the metals examined. Several metal concentrations also varied with geographic location and depth of water in which the turtles were captured. The second study examined the potential health effects of these pollutants in C. caretta. Regression analyses were used to compare physiological (blood) parameters to metal concentrations. The significant associations between several physiological parameters and several nonessential toxic metals suggest that heavy metal pollution may influence the physiology and, potentially, the health of sea turtles. However, this study is limited in that it can only identify associations and cannot discern causal relationships. Therefore, further research is needed to clarify the effects heavy metal pollution may have on sea turtle health. A better understanding of the effects of heavy metal pollution on health in this endangered species will facilitate more effective monitoring and protection in the future, enabling us to more effectively conserve these fascinating creatures.

▼ Nest counts from the largest subpopulation of the loggerhead sea turtle (Caretta caretta) in the Atlantic, peninsular Florida, have been declining since 1998. Analyzing trends of nests and adult females is insufficient to determine the overall status of a sea turtle population, due to variation in nesting frequency and a 25 – 35 year time lag between hatching and maturation. While nest numbers of this threatened species have declined by 50% since 1998, catches of juvenile turtles in many areas have increased. Better assessment of population status and diagnosis of the causes of population trends are possible if we examine existing data on changes in abundance and size distribution from in–water surveys of juvenile and subadult turtles as well as adults. I have plotted the length frequency data and catch rates of neritic turtles (juvenile, subadult and adult turtles that inhabit nearshore waters) collected from 1980 – 2007 at 4 in–water sites ranging from North Carolina to Florida (N=10,486). I also examined the length distributions recorded from strandings of dead turtles found on beaches in the Gulf of Mexico (N=4,308) and along the U.S. east coast (N=10,918) from 1990 – 2005. I found a similar pattern in length distribution shifts over time, which provides compelling evidence that the data are revealing true population change. The data suggest an increase in the overall abundance of juvenile turtles in the southeast U.S. since the late 1990s and an increase in the median size of neritic juveniles (40 – 90 cm) since 1990. There has also been a reduction in the number and proportion of small (<55 cm) juveniles since 2000 in some areas; these are considered “recruits” to the neritic feeding areas on the continental shelf. The shift in median size of juveniles coupled with the increased abundance in North Carolina and Florida indicate that there may be a large cohort or group of similar sized turtles that should reach maturity in the next decade. Changes in length frequency through time could indicate changes in recruitment, survival rates, or behavior, and translating length to age requires a good estimate of variance in growth rates. I developed an individual–based growth model using variance estimated through a new technique that measures growth using increments measured in cross sections of the humerus bone of stranded turtles. The technique permits a reconstruction of the growth history of individual turtles. While the growth patterns are clearly not a smooth, asymptotic function over length and time, there is some consistency among individuals. My re–sampling analysis of growth from 92 turtles provided an estimate of 30.74 years (95% CI = 23.82 – 37.66) required for a U.S. loggerhead turtle to grow from 20 cm (age 1 or 2) to 90 cm. This analysis will improve our estimates of the mean and variance in the length of time loggerheads are spending in various habitats and life stages, and improve future demographic models to determine population status. My analyses incorporate multiple data sets and techniques to… Advisors/Committee Members: Heppell, Selina S. (advisor), Sampson, David (committee member).

Sea turtle hatchlings emerge from their nest and quickly crawl to the surf. During the crawl, hatchlings may encounter threats, biotic and abiotic, which can affect their ability to successfully reach the surf. The impact of these threats on hatchling survival during that crawl is largely undocumented. Current methods used to estimate cohort recruitment rely heavily on nest inventory data. This method, however, does not account for post-emergent hatchling mortality that occurs during the crawl. During the 2017-2018 nesting seasons, I quantified the fates of 1,379 loggerhead (Caretta caretta) hatchlings from 26 nest emergences during their crawl from the nest to the surf on the east and west coasts of Florida. I documented hatchling fates at 5 Florida nesting beaches: Wabasso, Boca Raton, Keewaydin Island, Naples, and Anna Maria Island. Overall, 6.5% of all emergent hatchlings died during the crawl from the nests to the surf. Ghost crabs, night herons, foxes, and coyotes killed hatchlings and photopollution and barriers on the beach (both abiotic threats) caused hatchling mortality. Anthropogenic (abiotic) threats accounted for more mortality than did predators. In order to assess how beach urbanization impacts hatchling mortality, I categorized each study site as urban (Wabasso and Naples), intermediate (Anna Maria Island and Boca Raton), or natural (Keewaydin Island) based on the relative levels of shoreline development and human activity at each beach. Sites with intermediate levels of urbanization accounted for greater levels of hatchling mortality than at other beaches due to the absolutely larger numbers of hatchlings lost to a disorientation event and to a beach barrier. Given the small numbers of emergences, at all sites, only a small proportion of the hatchlings mortalities (e.g., between 3 and 12 percent), site type could not be rigorously used as a discriminator. My results provide a better understanding of how specific environmental threats contribute to hatchling mortality. While nest-to-surf mortality is relatively low, its cumulative costs add up to several hundreds of thousands of hatchlings. Armed with this information, nesting beach managers can assess risks and focus their efforts to implement the most effective management practices to minimize losses of this imperiled species.

▼ This dissertation examines the movement and foraging of 4 species of sea turtles using satellite telemetry, remote sensing of environmental variables, and distribution of Marine Protected Areas (MPAs). I use a switching space-state model (SSSM) to determine changes in behavior of leatherback turtles and 3 Cheloniidae species to identify foraging areas, migration pathways, spatial overlap among the 4 species, and the use of MPAs by the tracked turtles. Foraging in the marine environment is challenging due to the patchiness of food, often a result of oceanic features. By connecting oceanic features and animal movements, it is possible to identify foraging areas, migration pathways, and the associated environmental factors of these areas in the seascape. Remote sensing imagery was used to compare 7 environmental variables associated with the different behaviors of satellite tracked sea turtles. Leatherback turtles conduct long distance, wandering migrations between nesting beaches and foraging grounds making it difficult to determine changes between migration and foraging behavior. A SSSM was used to differentiate behavior modes and identify important foraging areas of satellite tracked leatherback turtles (Chapter 2). In contrast, Cheloniidae generally conduct shorter migrations to the same foraging areas allowing clear changes in behavior to be identified using a SSSM. Based on the SSSM behavioral states, critically important foraging areas for 3 Cheloniidae species were identified and characterized (Chapter 3). Satellite telemetry data were used for all 4 species to evaluate spatial overlap among the 4 species and the use of MPAs by tracked sea turtles (Chapter 4). The results suggest that leatherback and loggerhead turtles have regional or multiple foraging strategies and that protection efforts focused on North Atlantic leatherback turtles could also protect other species of sea turtles. The identification of sea turtle foraging and migration areas could be used to strengthen protections in current MPAs; justify the creation of new MPAs; and support development, or strengthening, of international agreements to protect sea turtles.

The eggs of all sea turtle species develop in underground nests on oceanic nesting beaches. Eggs are unattended and their incubation conditions are subject to effects of the environment. Nest temperature influences various aspects of hatchling biology, including sex determination. Past studies identified that sea turtle embryos have a warm female cool male response pattern and rainfall has been thought to cool nest temperature. The effects of rainfall or periods of drought were often inferred but not verified. Using laboratory and field studies, I examined how changes in environmental factors during incubation, particularly sand moisture, can affect nest conditions and hatchling biology. I derived temperature-sex ratio response curves for eggs incubated at different moisture levels to determine the effect of moisture on how embryos respond to temperature. I also studied how increasing moisture levels in relocated nests through daily watering influence nest conditions and discuss if this method is an effective mitigation strategy for the detrimental effects of increasing temperatures on embryo survival and sex ratios. I investigated how environmental factors, nest conditions, and hatchling biology can differ among sites on a nesting beach. Extreme moisture conditions, both low and high, result in a narrower transition between one sex ratio bias to another. I demonstrated that watering nests decreases nest temperatures and increases hatching success but watering has a minimal impact on sex ratios. Ambient beach conditions vary slightly in air temperature, rainfall, solar radiation, and humidity, depending on beach location. Nest conditions such as nest temperature and moisture also differ, but hatching success and sex ratios do not vary among different sites on the same nesting beach in Boca Raton, Florida. Ultimately, these studies together help identify and demonstrate how these environmental factors and drivers can affect the nest environment during incubation. Further developing our understanding of environmental factors, particularly nest moisture, and their variability will provide better predictions of future climate change effects and perhaps create more effective mitigation strategies.

▼ Bycatch, or the incidental capture of non-target species, has been implicated as one of the main factors leading to population declines of many large marine vertebrates, including sea turtles. To effectively manage and conserve these long-lived species, their marine distribution, high use areas, foraging habitats, and regions of highest likelihood of interaction with fisheries must be understood. I analyzed the movements and habitat use of satellite tracked juvenile loggerhead sea turtles (Caretta caretta) in the Southwestern Atlantic Ocean, a poorly studied region with high turtle-fisheries interactions. Between July 2006 and March 2010, 27 satellite transmitters were deployed at sea on juvenile loggerheads captured as bycatch in the Uruguayan and Brazilian pelagic longline fishing vessels. I characterized the broad-scale behavioral patterns, inter-seasonal variability, and general high use areas for 26 juvenile turtles, which were tracked for 259±159 days between latitudes of 25-45°S and longitudes 35-54°W. The high use areas for the tracked turtles were over the continental shelf and slope within the Uruguayan and Brazilian Economic Exclusive Zones, and in oceanic international waters between the Rio Grande Rise and the continental slope off of southern Brazil. Diving information was available for 5 of the tagged turtles; the maximum dive depth recorded varied between 100-300m depths, and two turtles demonstrated potential bottom-feeding behaviors by diving to depths that corresponded with the bathymetry at their location. The mean sea surface temperature encountered by turtles was 19.8±2.3°C (10.21°C-28.4°C) and turtles showed an affinity for mesotrophic waters (0.458±1.012 mg/m³ chlorophyll-a). Overall, broad scale latitudinal movements of juvenile loggerheads varied by season and sea surface temperature. Because recent studies on marine megafauna movements have highlighted that ocean currents can have an important effect on movement paths, I decoupled active foraging behavior from likely passive movement of tracked juvenile loggerheads in ocean currents. Using First Passage Time analysis; a method to measure changes in movement patterns along a pathway through the environment, and generalized additive mixed models, I quantified similarities in the movement patterns and habitat "affinities" of the turtles and surface drifters in the ocean. Turtles and drifters both exhibited movement patterns that could be classified as likely "foraging behavior" at a spatial scale of 80km. This corresponds to the identified scale of eddies in the Southwestern Atlantic Ocean, which may suggest that passive movement of turtles in ocean currents largely drives their scale of search. Current velocity and sea floor depth were the most important variables correlated with both turtle and drifter movement patterns at that scale. Both turtles and drifters generally showed a negative relationship between first passage time and current velocities. Some differences between turtle and drifter behavior were evident, particularly on the… Advisors/Committee Members: Heppell, Selina S. (advisor), Suryan, Robert M. (committee member).

▼ Loggerhead (Caretta caretta) and leatherback (Dermochelys coriacea) sea turtles as well as their eggs and hatchlings have been protected on their nesting beach in South Africa (SA) since 1963. Both nesting populations were expected to show similar trends in recovery following the application of identical protection and conservation measures. The loggerhead nesting population has responded favourably to these protection efforts. In contrast, the leatherback nesting population showed an initial increase but is currently stable. The reason for this difference in response is thought to be due to differential offshore mortality of these two species. This prompted an investigation into the different sources of sea turtle mortality in the South Western Indian Ocean (SWIO). Specific aims were to identify and quantify sources of loggerhead and leatherback mortality on nesting beaches as well as in the oceans. Reasonable survivorship at all age classes is important to ensure recruitment of new nesting individuals into sea turtle populations. Mortality of nests, eggs per nest and hatchlings were quantified over two seasons for the loggerheads and leatherbacks nesting in SA. The beach was patrolled on foot to encounter and record females emerging from the ocean and later, hatchlings from their nests. The nests were then monitored during the incubation period and excavated once hatched. The fates of 925 nests were determined during these two nesting seasons (2009/2010 and 2010/2011). The main source of loggerhead and leatherback nest destruction was predation (8.6 percent and 15.7 percent respectively) followed by nest erosion (2.2 percent and 6.3 percent respectively). Overall nest success was high but higher for loggerheads (89 percent) than for leatherbacks (78 percent). The main cause of egg mortality for both species was early developmental arrest, followed by predation by ants and ghost crabs. Hatchlings en route to the sea were almost exclusively predated by ghost crabs (4.2 percent of emerged loggerhead hatchlings and 3.2 percent of emerged leatherback hatchlings). It appears that both species benefit from the coastal conservation efforts. When sea turtles leave the nesting beach, either as hatchlings or adults, conservation and monitoring becomes more difficult and sea turtles are exposed to a multitude of threats, including anthropogenic threats. Age classes tend to be spatially separated due to different habitat and dietary requirements. The type of threat sea turtles are exposed to thus depends on the current age class. Offshore sources of mortality in the SWIO were identified and where possible loggerhead and leatherback mortality was quantified and mapped spatially. Loggerheads were mostly exposed to and had the highest mortality in the artisanal fisheries in the SWIO (> 1000 per annum), inshore trawling (ca. 41 per annum), shark nets (protective gill nets) (21.6 ± 6.7 per annum) and the pelagic longline fishery (5.0 ± 4.4 per annum). In contrast, leatherbacks with a pelagic lifestyle, were mostly exposed to pelagic… Advisors/Committee Members: Nel, R Dr.

The purpose of this interdisciplinary study was to provide information useful for the development of management policies for Rethymno, Crete which hosts an important loggerhead turtle rookery for the Mediterranean region and is included in the EU’s NATURA 2000 network. I used satellite telemetry, data loggers and ultrasonography to study the behavior of sea turtles during the interesting interval. By satellite tracking 21 turtles I identified internesting habitat utilized by loggerheads, which extended along the northern coast of Crete. Twenty-five percent of turtles exhibited low site fidelity, likely depositing at least one clutch in areas up to 150 km away. MCP and Kernel Density analyses revealed high intensity use areas indicating that existing boundaries of the NATURA 2000 site were insufficient to protect this population. Some females (n = 4) overwintered in neritic habitats around Crete. I studied the diving behavior of 33 loggerhead turtles and found that diving behaviors were consistent with energy conservation strategies. Dives occurred at depths shallower than 10 m (data loggers: 89.2%, n = 8,241; transmitters: 90.1%, n = 30,804), indicating selection for habitats providing protection. Using x2 goodness of fit tests and ANOVA analyses, I found variation in diving behavior among individual turtles and at different times of day. More active behavioral patterns indicated selection for warmer waters or foraging. Females spent > 95% of their time in the top 5 m of the water column between 11:00 and 19:00. I visited 18 ports around Crete, conducting 101 semi-structured, questionnaire based interviews with small-scale fishermen. There was a link between observed decreases in catch (reported by 96.0% of respondents), increased fishing effort and an increase in intensity of interactions with sea turtles. Fishers discussed damages resulting from these interactions, but sea turtles were thought to pose limited (52.5%) or no threat (21.2%). Interactions with large marine vertebrates were included in the ‘top three challenges’ faced by 66% of respondents, who indicated that the government should provide compensations, suggesting that it was indispensable to prevent intentional killings of animals seen as threats. Respondents also discussed establishing MPAs as favorable interventions for regenerating fish stocks. They also suggested that closures would be acceptable, especially if temporary and combined with compensation for curtailed fishing access.

▼ Mitochondrial DNA polymorphisms have been widely utilized to assess demographic connectivity of marine turtle rookeries, including those of the southeastern United States of America (USA). This region hosts the largest nesting aggregation of loggerhead turtles in the Atlantic and one of two globally significant nesting assemblages for the species. Determining the stock structure of the nesting aggregation is important for defining demographically independent nesting populations (management units) and providing appropriate baseline data for mixed stock analyses of foraging aggregations and stranded turtles. Previous studies based on a 390 base pair fragment of the mitochondrial control region partitioned the southeastern USA loggerhead turtle nesting aggregation into four management units. I reassessed the population structure of the nesting aggregation using 834 novel samples collected from North Carolina through the Florida panhandle as well as published haplotype frequency data. Pairwise FST comparisons, exact tests of population differentiation, and analysis of molecular variance (AMOVA) supported the presence of six management units corresponding to beaches from 1) North Carolina through northeastern Florida, 2) central eastern Florida, 3) southern Florida (southeastern and southwestern), 4) Dry Tortugas, Florida, 5) central western Florida (Sarasota County), and 6) northwest Florida. Despite the increased resolution gained from expanded sampling and larger sample sizes, the relationship of southernmost rookeries on the Gulf and Atlantic coasts of Florida remained unresolved. To address this question and assess the utility of an expanded control region fragment (817 bp) to refine stock structure, I analyzed 2,260 samples representing twelve rookeries of the southeastern USA aggregation as well as the Cay Sal, Bahamas rookery. This analysis supported the six management units suggested by the earlier study and additionally differentiated southeastern and southwestern Florida as distinct management units. The Cay Sal and Dry Tortugas rookeries were not genetically differentiated and were grouped as a single management unit, although it is probable that these distant rookeries are demographically isolated. As previously demonstrated by a published study, use of the larger control region fragment significantly increased population structure detected between western and eastern Atlantic loggerhead turtle rookeries. However, expanded sequences did not significantly improve resolution of structure among rookeries comprising the southeastern USA nesting aggregation in most comparisons, which were dominated by two common control region haplotypes. The single exception was southeastern Florida rookeries compared to all others because of the high percentage of CC-A1.3 relative to the common CC-A1.1. Given the ability of marine turtles to colonize sites far from their natal regions and the slow evolutionary rate of the mitochondrial genome relative to many other vertebrates, haplotype sharing is a common phenomenon among…

▼ The beaches of Broward County, Florida are a prevalent nesting site for loggerhead (Caretta caretta) sea turtles, however extensive beach erosion is threatening critical nesting habitat. Beach renourishment, the process of transporting offshore or upland sediment onshore, is a widely used method of replenishing lost sand. However, renourishment can negatively affect sea turtle nesting habitat by increasing beach compaction; the resistance to applied pressure in pounds per square inch (psi). Increased sand compaction impedes the digging of the female which affects nesting success. The influence of beach compaction on sea turtle nesting patterns has never been previously examined over the course of a nesting season on Hillsboro and Deerfield Beach. Therefore, this study was designed to examine beach compaction data for Hillsboro, a mostly natural beach, and Deerfield, a completely renourished beach, during the 2010 nesting season and analyze the compaction data against 2010 nest and false crawl (FC, non-nesting emergence) data. Compaction readings were collected during every other week March-October using a soil compaction meter at every other street address along three beach positions, the dune base, mid-beach, and average high tide line (HTL); and at three depths, 15 cm, 30 cm, and 45 cm. Values were not statistically different throughout the season for each beach, so seasonal mean compaction values were used for each beach position and depth. Hillsboro compaction values were rarely over 500 psi (35 kg/cm2), even at 45 cm depth. Deerfield compaction values exceeded the 600 psi (42kg/cm2) measurement limit of the meter in approximately 60% of the compaction values at 30 cm or 45 cm depth. Sand compaction data was analyzed for any trends between beaches as well as within each beach. Historical data shows higher loggerhead nesting success, the number of nests/total number of crawls (including FC) x 100, on Hillsboro Beach than on Deerfield Beach. The average beach compaction values were compared to nesting success and to nest and FC density within each station area. There was a significant inverse relationship (p<0.05) between beach compaction and nesting success at each of the beach positions and depths, when both Hillsboro and Deerfield Beaches were analyzed together, except at the Mid 30 cm and Dune 45 cm depth. The strongest relationship for the combined beaches was at the HTL 15 cm depth (R2=0.3821, p<0.001). When Hillsboro was analyzed alone, beach compaction and nesting success was only significantly inversely related (R2=0.0875, p<0.02) at the HTL 15 cm depth. This demonstrates that while increased beach compaction may partially influence nesting success, there are likely other beach characteristics that contribute to nest site selection of loggerheads in Northern Broward County. The inverse relationship between Hillsboro mean beach compaction and nest density (nests per meter) was significant only at the HTL 15cm depth (p<0.002) and the inverse relationship between mean beach compaction and false crawl density…

O objetivo deste trabalho foi analisar a ecologia alimentar da tartaruga-cabeçuda Caretta caretta no litoral do Paraná e verificar se há diferença na alimentação de indivíduos juvenis e adultos, por meio da análise de isótopos estáveis de carbono e de nitrogênio. Foram coletados organismos da base da cadeia trófica (seston), 19 espécies de presas (n=94 espécimes) que compreenderam moluscos, crustáceos e peixes teleósteos, e 20 espécimes de tartarugas da espécie C. caretta encontradas encalhadas mortas nas praias do litoral do estado (12 juvenis e 8 adultos). Foram analisadas as razões isotópicas em alíquotas do tecido muscular das tartarugas e de suas presas. Para a razão de isótopos de carbono, os moluscos apresentaram valores entre -16,9 e -13,7, os peixes entre -27 e -15, os crustáceos entre -18,8 e -15,5 e C. caretta valores entre -19,5 e -16,0. Já para a razão de nitrogênio, os moluscos apresentaram valores entre 10,3 e 13,9, os peixes entre 8,9 e 14,8, os crustáceos entre 9,5 e 14,3 e as tartarugas entre 9,9 e 18,3. Separando-se as tartarugas por classe de tamanho, os juvenis apresentaram valores médios de -18,4 e 12,9 e os adultos de -16,8 e 16,2, para as razões dos isótopos de carbono e de nitrogênio, respectivamente. As espécies de moluscos apresentaram valores para a razão isotópica de carbono mais altos que as tartarugas, indicando que poderiam não ser presas diretas da espécie, sendo assim, levantou-se a hipótese de que foram predados crustáceos ermitões no momento que utilizavam as conchas vazias. Os resultados das razões de isótopos de carbono e de nitrogênio apontam os peixes teleósteos como presas importantes, corroborando com o observado em outros estudos. Com relação as classes de maturidade, os valores para as duas razões isotópicas tenderam a aumentar com o aumento do comprimento curvilíneo de carapaça. Foi significativa a diferença nos valores entre juvenis e adultos, para ambas as razões isotópicas, mostrando que se alimentam de presas diferentes (Teste T de Student, p-valor < 0,05). Desta forma, levantou-se a hipótese de os juvenis estarem passando por uma fase de transição, quando se alimentam em diferentes ambientes, ou terem se fixado na zona nerítica há pouco tempo. Já os adultos estão se alimentando de presas de níveis tróficos mais altos que os juvenis, por isso a diferença nas razões dos isótopos. Conclui-se assim, que adultos e juvenis de C. caretta se alimentam de forma distinta no litoral do Paraná e ocupam diferentes níveis tróficos.
