Local community perceptions of sea turtle egg use in Tortuguero, Costa Rica

AbstractOstional in Costa Rica is the second largest nesting site of the olive ridley sea turtle Lepidochelys olivacea, which is categorized as Vulnerable on the IUCN Red List. In Ostional the local community helps maintain the nesting site and collects olive ridley eggs for consumption and trade within Costa Rica. Since its inception in 1987 the egg harvesting project has integrated sea turtle conservation with community development. We assessed the current status of this project in terms of community awareness, dependency, involvement and perceptions, using a household survey and semi-structured interviews with key informants. We also compared some of our findings with those of previous studies at the site, finding that the project has fewer dependents, primary livelihood activities have shifted towards tourism and hospitality, and respondents are more aware about environmental conservation and stewardship. We map outcomes of the project with the Sustainable Livelihoods Framework, and suggest that further capacity building for research and tourism could contribute towards sustaining the turtle population, local livelihoods, and the community-based conservation institution.

<p>In the face of the current global sustainability challenge, seeking out and strengthening sustainable alternative methods for community development has become an urgent task for development professionals and academics. In order to explore one of such alternatives, in this thesis I draw on research conducted with the Associación de Desarollo Integral de Ostional (ADIO). Located on Costa Rica’s rural Pacific coast, ADIO was initiated by the local community of Ostional and resulted in the Project of Sustainable Use, Conservation and Management of the Olive Ridley Sea Turtle in 1987. Co-managed by the University of Costa Rica (UCR) and the Ministry of Natural Resources (MINAE), ADIO practices conservation and scientifically monitors the management of the Olive Ridley sea turtle species. Surplus eggs from the turtle arribadas (the mass nesting’s of sea turtles) at the optional beach are being legally harvested and marketed by ADIO. This project has successfully contributed to the protection of the Olive Ridley turtle population whilst returning socio-economic benefits into the community. The aim of this research is to gain a better understanding of ADIO’s work and the significance of ADIO to the local community. My research draws on the experiences of community members to identify their perception of the benefits of ADIO to their own community, and unpack areas in need of improvement. Qualitative data were collected from community members through: semi structured interviews, participant observation, a reflective workshop, a questionnaire and field notes. The findings of this research identify key elements for the success of ADIO, and demonstrate the benefit of this Project toward the sustainability of the local community. This research demonstrates that socio-economic benefits can be gained through appropriate community participation in sustainable conservation projects, which can further enhance the desire of the local community to be better stewards of natural resources. This thesis seeks to contribute in some small way to an existing body of knowledge on the topics of sustainability, community-run conservation, and development.</p>

Long Time

Marine mammals such as whales and dolphins have been known for a long time to host a very specific epizoic community on their skin. Less known however is the presence of a similar community on the carapaces of sea turtles. The present study is the first describing new taxa inhabiting sea turtle carapaces. Samples, collected from nesting olive ridley sea turtles (Lepidochelys olivacea) on Ostional Beach (Costa Rica), were studied using light and scanning electron microscopy. Two unknown small-celled gomphonemoid taxa were analysed in more detail and are described as two new genera, closely related to other gomphonemoid genera with septate girdle bands, such as Tripterion, Cuneolus and Gomphoseptatum. Chelonicola Majewska, De Stefano & Van de Vijver gen. nov. has a flat valve face, uniseriate striae composed of more than three areolae, simple external raphe endings, internally a siliceous flap over the proximal raphe endings and lives on mucilaginous stalks. Poulinea Majewska, De Stefano & Van de Vijver gen. nov. has at least one concave valve, uniseriate striae composed of only two elongated areolae, external distal raphe endings covered by thickened siliceous flaps and lives attached to the substrate by a mucilaginous pad. Chelonicola costaricensis Majewska, De Stefano & Van de Vijver sp. nov. and Poulinea lepidochelicola Majewska, De Stefano & Van de Vijver sp. nov. can be separated based on stria structure, girdle structure composed of more than 10 copulae, raphe structure and general valve outline. A cladistics analysis of putative members of the Rhoicospheniaceae indicates that the family is polyphyletic. Chelonicola and Poulinea are sister taxa, and form a monophyletic group with Cuneolus and Tripterion, but are not closely related to Rhoicosphenia, or other genera previously assigned to this family. Features used to help diagnose the family such as symmetry and presence of septa and pseudosepta are homoplastic across the raphid diatom tree of life.
