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>

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.

Women In Development

<p>This dissertation documents research conducted with the 'Asociacion de Mujeres de Acosta'  (AMA), in a mountainous rural region of Costa Rica, in Central America. AMA was originally set up to counter some negative effects of Costa Rican society, such as 'machismo'  and the rural depopulation of women to the capital San Jose. The association implemented a Women In Development (WID) approach, which enabled women to gather and generate an income. The aim of my research is to examine the evolution of AMA since its inception, and to assess its current status in light of international shifts in development policy from WID to Gender And Development (GAD). It provides a rare opportunity to assess an organisation's evolution and its impact on women over a 30-year period. It also enables me to build on Kindon and Odell's earlier research with the organisation in 1990. The research uses qualitative data collected through semi-structured interviews, participant observation, a focus group, a questionnaire and field notes, from five months of fieldwork in the community with members of AMA. The key findings show that AMA membership has decreased since its inception in 1980. Compared with results from previous research with AMA in 1990, my findings reveal that AMA has been slow to embrace international policy agendas and continues to adopt a WID approach. AMA does not yet reflect international and national development trends associated with gender and development, particularly in light of some similar organisations in Central and South America. While benefits have accrued to some of AMA members, they do not yet earn a decent wage to satisfy their needs. There are major intergenerational and interscalar issues, which are similar to those identified in 1990. These concerns are associated with power imbalances inside and outside of the association, traditional attitudes towards women due to the culture of 'machismo', and lack of appropriate information and funding sources. These issues appear to be stifling change and raise serious questions about the future sustainability of the association, as well as the relevance of international development policy changes for rural women in associations like AMA. Women of AMA are now looking for new projects and beginning to think about including men in the association. These slow changes, if enacted, may enable the organisation to survive another 30 years.</p>

The Bishnumati River is one of the major sources of water in Kathmandu city for domestic and agricultural uses. But the quality of the river environment has been degraded seriously since the last few years. This paper is an attempt to explore environmental condition along the Bishnumati River with specific focus on human activities, perception and institutional efforts in dealing with the river environment. Based on field observation, household survey, and key informant survey in eight segments along the river stretch from the city periphery to down town, the information acquired indicate that human activities related to environmentally sensitive phenomena were very much dominant in degrading the river environment. The local inhabitants were aware of the river environmental conservation. The local public agencies were however not seriousness in implementing the waste management activities, but instead they practiced environmentally sensitive activities at the riverbanks. Efforts at both local community and public agencies levels are most warranted to protect the Bishnumati river environment from further degradation. The Geographical Journal of Nepal, Vol. 7, 2009: 53-60

AbstractThe Brazilian Sea Turtle Conservation Programme (TAMAR) was established in 1980 to protect sea turtles in Brazil and to re-establish their natural life cycle, which had been disrupted by humans. The programme is based on grassroots involvement by the coastal communities, and provides jobs and generates alternative sources of income. Within this framework, the mini-guides programme was created. It consists of a summer training course in which local children between 8 and 13 years old learn basic information about marine ecosystems and sea turtles, strategies to promote their conservation, and skills to interact effectively with tourists. After the course, children are given onsite experience by working as interns at the TAMAR visitor centre at Praia do Forte, on schedules designed to avoid conflicts with their studies at school. The children work closely with tourists, informing them about sea turtles and TAMAR's work; they also help the biologists in field activities. In this way, they enhance their own awareness, and by extension their families' and the community's concern about environmental conservation. Their involvement provides them not only with valuable skills, but also an extra source of income, thereby providing economic benefits to their families. The success of this programme is indicated by the excellent approval ratings given by the tourists visiting the area.

Nesting Sites

For endangered sea turtle populations, microbial pathogens of developing embryos are of concern at nesting sites around the globe. For olive ridley turtles, hatching success is markedly lower at mass-nesting sites than at solitary nesting beaches, a case presumably resulting from the abundance of decomposing eggs generated by nesting turtles destroying adjacent eggs. This organic input drives microbial activity, affecting the nest environment (i.e. pO2 and temperature), and reducing embryo survivorship and hatching success. However, the composition of microbial communities in nest sand has not been studied in detail and the presence of potential pathogens can, therefore, not be discounted. As a part of a larger study that investigated microbial abundance in nests, we employed high-throughput DNA sequencing to compare fungal and bacterial composition in nest sand from areas of disparate embryo survivorship. While we found no differences in alpha-diversity (mean operational taxonomic unit diversity within each site) among nesting areas, the microbial community composition of each area was distinct, and differences in community structure corresponded with variable hatching success. Some sequences of potential sea turtle egg pathogens were obtained (e.g. Fusarium solani species complex), but were in low relative abundance, and their presence was not associated with low hatching success. Our results from the arribada beach at Ostional, Costa Rica, provide further evidence that the physical characteristics of the nest (including those that determine microbial composition and activity) are likely more relevant to hatching success than the presence of potential pathogens or microbial community structure alone.
