“…The current results are in accordance with those reported by Anzanza-Ricardo et al ( 2015), who noted that in sea turtle conservation programs, resource management is crucial to achieve an adequate cost-benefit balance, and Hart et al (2018), who stated that an increase in and consolidation of conservation and monitoring activities will result in an increase in the number of nests. However, monitoring and conservation program evaluation continue to be a challenge due to complications that can occur during data collection and difficulty in obtaining financial incentives to promote community participation that promote positive attitudes towards conservation and consistency in the collection of information (Godley et al, 2020).…”

Introduction: Although olive ridley sea turtles (Lepidochelys olivacea) are the most abundant sea turtles in the world, quantitative information is scarce and unevenly distributed among regions. There are many management and conservation programs for this species, and assessments are necessary to identify nesting trends and effectively manage current conservation programs. PROTORMAR-UAS is a Research and Conservation program for the olive ridley turtle created by the Autonomous University of Sinaloa, Mexico. The program utilizes two biological stations: Santuario Playa Ceuta (SPC) and Playa Caimanero (PC). Objective: To evaluate the nesting trend of olive ridley turtles on two beaches in Northwestern Mexico and to predict prospective nesting trends for the next 30 years. Methods: Using annual nesting data collected over 40 years at SPC (1976-2016) and 30 years at PC (1986-2016), we evaluated nesting trends, hatching success, predation and poaching of olive ridley turtles on the two beaches in Northwestern Mexico. Then, prospective nesting estimates for the next 30 years were calculated predictive time series model. Results: A positive and significant correlation was identified between the number of annual nests and time for both beaches (rho = 0.850, P ≤ 0.01 for SPC; rho = 0.677, P ≤ 0.01 for PC); the average hatching success rates were 65.09 at SPC and 60.72 % at PC. The predictive time-series model indicated that the numbers of nests will continue to increase through 2045, increasing three-fold at SPC and six-fold at PC with respect to the last year of monitoring. Conclusions: There was a clear positive trend in the number of olive ridley sea turtle nests at both sites, which is consistent with trends found in other recent studies from the region. Therefore, we suggest that PC be designated a legally protected nesting area since it is located within the latitudinal limits of olive ridley nesting and given the need for resources for camp operation considering increased nesting and current problems with predation and poaching. Because in Mexico operating a nesting beach without any protection status implies not having a budget for its management.

“…Human exploitation of sea turtles has occurred at unsustainable rates (Garland and Carthy 2010), leading to significant population declines and six of the seven species "threatened with extinction" (IUCN 2020). In many parts of the world, sustained conservation efforts, fishery management, and regulatory measures have recently resulted in the gradual stabilization and increase in sea turtle subpopulations (Godley et al 2020). However, some subpopulations show large declines (Mazaris et al 2017).…”

“…With increased demand from the wildlife trade industry, traditional harvesting of turtle eggs for subsistence has largely evolved into income-driven commercial exploitation in many parts of the world (Mancini and Koch 2009, Garland and Carthy 2010, Mohd Jani et al 2020. More recently, sea turtles are recognized for their non-consumptive values as flagship species for conservation and symbols for commercial purposes such as tourism (Waylen et al 2009, Godley et al 2020. Studies from Australia (Tisdell and Wilson 2002), Indonesia (Putra and Bailey 2007), Brazil (Pêgas 2009), Costa Rica (Campbell 2007, Mejías-Balsalobre et al 2021), and Nicaragua (Madrigal-Ballestero and Jurado 2017 show that tourism as a local economic alternative has helped reduce the commercialization and consumption of turtle eggs.…”

Sea turtles have been exploited at unsustainable rates globally. In Malaysia, their populations have faced serious declines because of diverse anthropogenic stressors including turtle egg consumption. Redang Island, off the northeast coast of Peninsular Malaysia, is an important rookery for green sea turtles (Chelonia mydas) in Southeast Asia. The local community has depended on turtle eggs as a food and livelihood source for decades. Owing to the precipitous decline in sea turtles, the main nesting beaches became legally protected in 2007. Some turtle egg consumption continues despite the protection measures and long-term awareness raising. In our study, we assess the prevalence, motivations, demographic factors, and perceptions influencing turtle egg consumption and conservation. Through semi-structured interviews, we surveyed 73 respondents in Redang village. The interviews show that turtle egg consumption has decreased since the initiation of protection measures, making the eggs expensive and difficult to access. Using binary logistic regression, we found that the respondents' education level and occupation were significant predictors. Education level was negatively correlated with age. People with higher levels of education (younger people) were less likely to eat turtle eggs, possibly on account of changing cultural beliefs and taste preferences, as well as increasing awareness. Those working in the tourism industry were less likely to consume eggs. The growth in tourism has served as an alternative to livelihoods that were dependent on the consumptive use of natural resources such as fishing and turtle egg collection. Further, tourism has catalyzed a shift from consumptive to nonconsumptive uses of sea turtles. Many locals perceived the protection of beaches as important, without which they claimed that turtle populations would go extinct. This research shows that addressing sea turtle conservation requires a multi-targeted approach of regulating sea turtle egg collection, providing economic alternatives such as tourism and long-term awareness raising.

“…Sin embargo, a pesar de estar protegida por leyes y tratados nacionales e internacionales, es la tortuga marina con mayor presión antrópica (Meylan y Donelly 1999;Mortimer y Donelly, 2008;Barrientos-Muñoz et al, 2015). Además del consumo de su carne y huevos, el tráfico ilegal de su caparazón para la elaboración de artesanías, utensilios de cocina y espuelas para peleas de gallos, es la principal razón de su estado crítico a nivel mundial y local (Meylan, 1999;Reuter y Allan, 2006;Barrientos-Muñoz et al, 2015, 2020Ramírez-Gallego y Barrientos-Muñoz, 2020, 2021.…”

Se describen los procesos de conservación y ecología de anidación de la tortuga carey (Eretmochelys imbricata), producto del monitoreo sistemático entre 2018 y 2019 en el corregimiento de Rincón del Mar, San Onofre, Sucre. Se registraron seis nidadas de tortuga carey, todos fueron dejadas in situ y un nido fue saqueado por humanos. Las hembras desovaron un total de 761 huevos en cinco nidadas (promedio ± DE: 152,2 ± 15,5 huevos por nidada). El éxito de eclosión fue en promedio 78,2 ± 12,4 % y el éxito de emergencia fue en promedio 74,7 ± 14,1 % (n = 5). El periodo de incubación fue en promedio de 54 ± 7,8 días (n = 4). Fueron liberadas 591 crías al mar, de las cuales 22 (3,72 %), fueron rescatadas y liberadas con la comunidad. Además, se realizaron mediciones físicas de los nidos (ancho, profundidad, distancia a la playa), medidas morfométricas de los neonatos (ARC, LRC y peso) y se identificaron amenazas en el sector. Nuestros resultados contribuyen al conocimiento del estado actual de la tortuga carey, así como lo indispensable de la participación comunitaria para su conservación en Rincón del Mar.
