“…Continuing the comparison with T. s. elegans , S. bealei produces smaller clutches (average 2.2 eggs) of larger eggs, while T. s. elegans produces larger clutches (average 12.5 eggs) of smaller eggs. Consequently, the RCM of S. bealei (5.14–12.21%) was similar to other freshwater turtle species: C. mouhotii (6.9–14.6%, Wang et al, 2011), C. flavomarginata (2.3–9.2%, Chen & Lue, 1999) and T. s. scripta (3–17%, Ernst & Lovich, 2009). Therefore, the total volume for eggs is relatively similar, but different species take different approaches to eggs—many small or few big.…”

“…Developing and undeveloping eggs were distinguished by the presence of a white spot on the eggshell. Relative egg mass (REM) (mean egg weight/body weight before oviposition) and relative clutch mass (RCM) (clutch weight/body weight before oviposition = REM × clutch size) were calculated for each gravid female as estimates of reproductive effort (Wang et al, 2011). To monitor the temperature and humidity of the nest during incubation, we buried a data logger (HOBO U23-001, Onset Computer Inc., Bourne, MA, USA) at 10 cm distance to the nest and at the same depth.…”

The Beal’s-eyed turtle (Sacalia bealei) is endemic to southeastern China and endangered due to poaching and habitat loss. Knowledge of S. bealei ecology is lacking and this study provides baseline information of its reproduction in a natural environment. We studied the reproductive ecology of S. bealei using X-ray, spool-and-line tracking, and direct observation. Six nesting females were successfully tracked and their nesting behaviors are documented in detail. Females produced a mean clutch size of 2.2 eggs (range 1–3). The hard-shelled eggs were ellipsoidal with a mean length of 45.50 mm, a mean width of 23.20 mm, and mean weight of 14.8 g. The relative clutch mass was 9.47%, while the relative egg mass was 4.60%. The mean incubation period was 94.7 days with a mean nest temperature of 25.08 °C. Hatchlings had a mean weight of 9.7 g, carapace length of 40.1 mm, carapace width of 33.3 mm, carapace height of 17.4 mm, plastron length of 31.6 mm, and plastron width of 25.4 mm. The results of this study provide important information to inform conservation plans and ex-situ breeding for this endangered species.

In China, Hainan Island is a priority area for turtle conservation because of its biodiversity. Over the years, errors in turtle taxonomy and distribution have been made in the scientific literature, perpetuating into relevant laws and government documents and affecting conservation and management. In the present article, we describe the species of nonmarine turtles on Hainan Island, China, based on literature, museum specimens, and field surveys during the past 27 yrs. Historically, 23 nonmarine turtle species were recorded on Hainan Island. Among them, 9 species should be removed due to errors: 5 species are not naturally distributed on Hainan Island (Manouria impressa, Sacalia bealei, Cuora flavomarginata, Mauremys nigricans, and Mauremys reevesii), 3 are invalid hybrids (Ocadia philippeni, Sacalia pseudocellata, and Cuora serrata), and 1 is a synonym of another species (Mauremys megalocephala is a synonym of M. reevesii). In addition, of the 3 new species recorded from Hainan Island (Sacalia insulensis, Pelodiscus variegatus, and Pelodiscus parviformis), S. insulensis replaces Sacalia quadriocellata, P. variegatus is valid, and P. parviformis is likely an error. Therefore, there should be 12 nonmarine turtle species naturally found on Hainan Island: Platysternon megacephalum, Cuora galbinifrons, Cuora mouhotii, Cuora trifasciata, Geoemyda spengleri, Mauremys mutica, Mauremys sinensis, S. insulensis, Palea steindachneri, Pelochelys cantorii, Pelodiscus sinensis, and P. variegatus. Clarifying the presence and distribution of nonmarine turtle species will provide a reference for future research and practical guidance for conservation management on this turtle-rich island.

“…Therefore, we recommend that a thick layer of leaves is provided to both aid in reducing stress and simulate a natural environment. Furthermore, these species, and a few others within the genus, differ from most in that they show a preference for nesting within the leaf-litter layer (Wang, Gong et al, 2011;L. Augustine & N. Haislip, pers.…”

Despite their historic commonality in the pet trade, there is still relatively little information published on the care and reproduction of the Cuora galbinifrons complex. Now recognized as three distinct species – Indochinese box turtle Cuora galbinifrons, Bourret's box turtle Cuora bourreti and Southern Vietnam box turtle Cuora picturata – this complex contains some of the world's most Critically Endangered chelonians. The following is a husbandry report for these species. Information was collected from North American studbook participants for the Association of Zoos and Aquariums Species Survival Plan, unpublished reports, websites and the available published literature. Various husbandry methods have proven successful; however, there have been few instances of consistent reproductive success. This paper aims to illuminate some husbandry practices in place at the time of writing and promote the sharing of information for future programmes.
