Over the past two decades, developing countries have recognized the economic value of attractive marine resources and the need to actively protect these resources. Many of these conservation projects rely on limiting extractive activities to protect habitats, which restricts local livelihoods, and promoting marine resource-based tourism to provide financing for conservation. Using a political ecology framework, this dissertation investigates two connected aspects of tourism and conservation: tourists' seafood consumption and the Go Blue Central America, a geotourism project initiated by National Geographic. It also explains the value of considering the local environmental knowledge of a diverse group of resource users, with a specific focus on professional scuba divers. Given the importance of scuba diving as an activity and tourism attractor on Utila, professional scuba divers on the island are well-positioned to serve as a source of environmental knowledge data on Utila's dive sites, including on their condition, species sightings, and changes over time. This knowledge is not without its problems as it may lead to conceptions of local participation that fail to include those actually from the community of concern. Thus, this dissertation calls attention to the possibilities of using divers' environmental knowledge in conservation and environmental management while also remaining attuned to the potential complications that may arise from doing so. Ultimately, this dissertation calls for the development of additional tourism alternatives and more comprehensive tourism planning and management which includes the potential for damage done by nonextractive resource users. For Utila, this will entail altering existing business practices to increase local ownership, shifting away from backpacker and budget oriented tourism toward a more expensive product, and involving more of the local community in the decision-making processes which affect tourism and the environment.

The Oxford English Dictionary defines 'omnifarious' as 'comprising or relating to all sorts or varieties', which quite accurately captures the very nature of octocorals and this thesis. The research reported here, aims to describe undocumented communities of coral reef organisms - the octocorals - which are an emergent dominant component within their threatened ecosystem of the Caribbean. Within the last four decades, coral reefs worldwide have experienced a precipitous plunge in many ecosystem services they provide, and most notably in the Caribbean. The foundation to reef resilience is structured on the ecosystem's ability to repair and restructure itself in the face of environmental shifts. These intricately complex strategies of resilience depend on repair mechanisms provided by a source of biodiversity, much of which remains poorly understood. This work explores many facets of the functioning within this potential future coral reef ecosystem. These reports are one of the most significant contributions to documenting and describing octocoral biodiversity (e.g. species, genetic, and community diversity) of the wider ecoregion of the Mesoamerican Barrier Reef System within the last three decades.
