Abstract Chelonia mydas in temperate areas exhibits behavioral changes for adapting to sea temperature fluctuations; however, prolonged exposure to cold temperatures can lead to hypothermia and thus hypothermic stunning events. Here we report an unusual stranding event of 90 green turtles recorded in a 12-d period in July 2012 in southeastern Uruguay, analyzing the event in an oceanographic and meteorological context. Monitoring such events provides a unique opportunity to understand the impact of hypothermic stunning on juvenile green turtle stocks that spend the entire year in this temperate region of the southwestern Atlantic Ocean.

Abstract Nest-site selection by most turtles affects the survival of females and their offspring. Although bog turtles (Glyptemys muhlenbergii) do not typically leave their wetlands for nesting, nest-site selection can impact hatching success and hatchling survival. Between 1974 and 2012, we monitored the fates of 258 bog turtle eggs incubated in the field and 91 eggs incubated under laboratory conditions from 11 different bogs, fens, or wetland complexes in New Jersey and Pennsylvania. Laboratory-incubated eggs exhibited the greatest hatching success (81%), but we did not detect a significant difference in hatching success between nests protected with predator excluder cages (43%) and unprotected nests (33%). However, we found significantly lower predation rates in protected nests, suggesting that while predator excluder cages successfully reduced predation, other environmental factors persisted to reduce egg survival in the field. Natural hatching success was potentially reduced by poor weather conditions, which may have resulted in embryo developmental problems, dehydration, or embryos drowning in the egg. Our results suggest that egg depredation, coupled with embryo developmental problems and infertility, are limiting factors to hatching success in our study populations. Using predator excluder cages to protect bog turtle eggs in the field, or incubating eggs in the laboratory and releasing hatchlings at original nesting areas, may be an effective conservation tool for recovering populations of this federally threatened species.

Abstract Sea turtles are globally endangered and face anthropogenic threats, such as direct harvest, bycatch, and habitat degradation. Genetic studies help identify connectivity between nesting and foraging grounds for conservation and management. However, information on genetic stock composition of green turtles (Chelonia mydas) in the South China Region (including Hong Kong, Guangdong Province, and Taiwan) is severely limited. In this study, mixed stock analysis based on the 760-bp mitochondrial DNA (mtDNA) control region of green turtles (n = 110) revealed that the primary source rookeries in the Pacific contributing to foraging green turtle aggregations in the South China Region were Peninsular Malaysia, Yap in the Federated States of Micronesia, Aru of Indonesia, Sulu Sea, northeastern Borneo, Republic of Marshall Islands, Wan-an of Taiwan, and the central Ryukyu and Yaeyama of Japan. This study is the first to investigate and report the source nesting populations of a relatively large number of foraging green turtles in the region. The genetic results also indicate possible use of coastal Guangdong, the Taiwan Strait, and the East China Sea as habitat by pelagic-phase green turtles hatched from nesting beaches in Taiwan and mainland China. As a precautionary approach for effective sea turtle conservation, conservation and management of each distinct green turtle source rookery as well as foraging aggregations sourced from multiple natal origins in the South China Region is needed to preserve genetic diversity for the species. Anthropogenic threats to nesting and foraging habitats and migratory pathways, such as direct take for trade and fishery impacts, should be thoroughly assessed and effectively mitigated by regional collaboration to sustain these populations.

Abstract Here we describe the effects of beach morphological features on loggerhead (Caretta caretta) nesting behavior on the barrier islands of the north-central Gulf of Mexico. Our results show that loggerhead crawl length decreases as beach slope increases, and our data comparing nest crawls (resulting in egg laying) versus false crawls (emergence onto the beach without laying eggs) suggest that beach slope and crawl length differ between the crawl types but elevation does not. We infer that loggerheads cue in to beach slope to reach a perceived elevation with reduced risk of inundation, crawling longer distances on flatter slopes compared with shorter distances on steep slopes, but that after this elevation is reached, other environmental variables may ultimately factor into the decision to lay eggs.

Abstract Knowledge of species-specific patterns of energy use is important for understanding the evolution of life histories as well as for determining how species might respond to alterations in environmental conditions. We measured standard metabolic rates (SMRs) in 59 Eastern Box Turtles (mass range = 106−510 g) and determined how differences in body mass and body temperature (20°C vs. 30°C) influenced SMRs. Rates of standard metabolism were significantly influenced by body mass at body temperatures of 20°C and 30°C and SMR was significantly higher at 30°C (Q10 = 3.04). There was significant among-individual variation in SMR and individuals with higher metabolism at 20°C also tended to have higher metabolism at 30°C.

Abstract After a control program for feral foxes was instigated, the monitor lizard Varanus panoptes has become the most common predator of loggerhead turtle nests at the Wreck Rock beach nesting aggregation adjacent to Deepwater National Park in southeastern Queensland. We empirically tested the efficacy of aluminum mesh cages, plastic mesh sheets, red flags, and hot chili powder in protecting loggerhead turtle nests from monitor lizard predation across 2 nesting seasons (2014–2015 and 2015–2016). Our study indicated that plastic mesh, when applied correctly, is a relatively inexpensive and effective way to prevent monitor lizard nest predation at sea turtle nesting beaches.

Abstract We studied the sexual dimorphism in body size and shape of Beal's eyed turtle, Sacalia bealei, by measuring 15 morphological characteristics of 68 adult individuals (40 females, 28 males) collected from Fujian Province, China. Females were slightly larger than males in carapace length with a sexual dimorphism index of 0.09. This translated into greater absolute values of females for all the traits we measured except for tail length, preanal tail length, and analia to supracaudal junction length. Comparisons between the sexes of size-corrected morphological traits indicated that females exhibited a longer plastron and higher carapace relative to carapace length, thereby providing a larger internal volume. Females also exhibited relatively wider heads. In males, the plastron was smaller and more indented than in females and the openings between the plastron and the carapace were also more developed. Overall, females were larger in size and displayed a more voluminous shell than did males while males had longer tails and larger spaces available to move the legs, head, and tail.

Abstract The giant South American river turtle (Podocnemis expansa) is the largest extant member of the suborder Pleurodira and the largest freshwater chelonian in South America. Owing to its size, its meat is sought for consumption and trade in the Amazon region. The aim of the present study was to investigate the reproductive behavior of 2 different populations of P. expansa. Allelic frequency variation was studied in 6 DNA microsatellite loci of recently hatched offspring from 8 nests on a beach in the municipality of Oriximiná in the state of Pará, Brazil. Multiple paternity was identified in all nests studied. Between 5 and 10 fathers contributed to each nest. Compared with previous studies, a greater frequency of multiple paternity and a greater number of fathers contributing to each nest were found in the present investigation. The results suggest that populations from different locations may exhibit different paternity patterns due to ecological or biological differences. By comparison with previous studies, we suggest that the differences in the number of nests, proportion of offspring per nest, and number of loci analyzed in each study may influence the frequency of multiple paternity detected.

Abstract The present study is the first to report the diet of 2 sympatric turtle species, Cuora mouhotii and Cuora galbinifrons. In Diaoluoshan Natural Reserve in Hainan Province, China, both species were observed to have an omnivorous diet; however, the composition of the diets was different between the species. The diet of C. mouhotii consisted of fungi, plants, earthworms, land snails, and insects, whereas the diet of C. galbinifrons included fungi, plants, earthworms, and lepidopterous larvae.
