This study focuses on communities in conservation in central Philippines, with reference to marine protected areas. It analyzes communities as intersections of multiple actors with stratified interests and power, involving complex processes of place-making, ecological knowledge, tenure, governance, markets, and negotiation with domestic and international non-governmental organisations (NGOs). As rights to places are fundamentally at issue with protected areas, matters of tenure are central for the study. And because marine protected areas (MPAs) are community-based, questions of local empowerment have equal centrality. / The ownership of rights to marine resources by village members is a necessary if not sufficient condition for the political empowerment of communities in conservation. The issue of property rights in the Philippines is irrevocably linked to issues of equity, as social actors confront prevailing unequal relations of power. The development of community commitment to the reconfigured arrangements of marine protected area establishment depends on substantial economic gains for marginalized villagers, an equitable distribution of those gain, the ecologically sound management of resources over which rights are negotiated and gains generated, and a socially meaningful realignment of relations of power among nested sources of authority. / My analysis points to the advantages of a reinforced community property regime that would call for measures by the national government to enhance villagers' tenure over their settlements and community waters (katubigang barangay). Such a regime is no panacea for the manifold social and environmental challenges faced by communities, but it would enable them to engage more confidently and constructively with state, NGO and other interests in conservation, and to address the real or perceived threats of dislocation by externally proposed schemes. / Two villages with MPAs in the province of Bohol in central Philippines serve as case study sites to explore intertwined social, economic and political variables that influence issues of conservation, equity and empowerment.

Evidence for the decline of marine biodiversity is being noted worldwide (Pauly and Watson, 2003). Indigenous peoples around the world have a key role to play in marine conservation efforts. With the collapse of many fisheries stocks, including stocks in the Georgia Strait of British Columbia, Canada, the Canadian Federal Government is pursuing conservation strategies such as Marine Protected Areas (MPAs). Section 35 of Canada's Constitution Act protects indigenous peoples' rights, such as the right to harvest natural resources for food, social and ceremonial use. Conservation efforts that potentially infringe upon Aboriginal rights secure a duty to consult and accommodate First Nations' interests on the Government of Canada. Indigenous peoples on Canada's West Coast ofen oppose the creation of MPAs as these have the potential to impact their indigenous rights. This opposition has contributed to the delay in the development of MPAs on the Pacific Coast of Canada. This research contributes to understanding of indigenous use of marine resources and how effective government proposed MPAs are in meeting the conservation goals and perspectives of the Hul'qumi'num peoples. First Nations' marine conservation and management principles, goals and objectives are explored, through a case study of a Central Coast Salish indigenous group, the Hul'qumi'num. These approaches are compared to current government principles and strategies. Some similarities exist between the two, although there are fundamental differences that may be dificult to reconcile. The Hul'qumi'num worldview that everything is connected has some similarities to ecosystem-based management where humans are viewed as part of the ecosystem. However, in a Hul'qumi'num philosophy, humans are a fundamental component of the ecosystem, whereas ecosystem-based management recognizes humans as part of the ecosystem in order to better manage anthropogenic impacts. Simply integrating traditional ecological knowledge in current management efforts does not go far enough to address the goal of reconnecting Hul'qumi'num Mustimuhw (people) to the marine environment and resources. Attitudes towards permanent no-take zones are influenced by beliefs such as limiting aboriginal rights by closing areas to harvesting. Participant support for permanent no-take zones was significantly increased if the notake areas were proposed and managed by Hul'qumi'num. Community-based management, where First Nations have a legitimate role in managing may begin to address this gap. Further exploration of how to accommodate First Nations' principles, goals and objectives directly in marine conservation and management of marine resources will increase the success of marine conservation eforts on the Pacific Coast of Canada. This thesis provides the beginning of a foundation to bridge between current government conservation strategies and traditional management systems. The integration of social sciences and natural sciences in conservation eforts will increase the acceptance and success of conserving marine ecosystems.

The projects described in this dissertation are focused on compounds derived from the marine environment. Chapter 1 gives an introduction to the study of marine natural products to treat human ailments and a thorough review on compounds from lithistid sponges that have been isolated or synthesized since 2000. Chapter 2 describes the isolation and structure elucidation of two sesquiterpene substituted benzoquinone derivatives, petrosiquinones A and B, from a deep-water marine sponge from the Family Petrosiidae. Although initially purified following activity in a (Sb(B-catenin/Tcf4 assay they were later followed using tumor cell line cytotoxicity assays. Petrosiquinone A was the more active of the two compounds with moderate cytotoxicity in the DLD-1, PANC-1, and AsPC-1 cell lines. In Chapter 3, the isolation and structure elucidation of two new marine-derived macrolides, madeirolide A and B, isolated from a deep-water lithistid sponge of the genus Leiodermatium is described. / They were isolated using numerous chromatographic techniques and the structures were elucidated on the basis of 1D and 2D NMR spectra coupled with high resolution-mass spectrometry (HR-MS) data. Madeirolide A and B inhibited the growth of the fungal pathogen Candida albicans with minimum inhibitory concentrations (MIC) of 12.5 and 25 (So(Bg/mL, respectively, but were not cytotoxic in tumor cell assays under the conditions tested. Chapter 4 describes work performed to determine the molecular target of lasonolide A using affinity chromatography. The target of lasonolide A is of interest since lasonolide A is known to kill cancer cells in vitro through a unique mechanism. / This chapter highlights the research performed to create an affinity matrix with immobilized lasonolide. A target has not been confirmed but there are a number of interesting hits that are being pursued. In Chapter 5, a liquid chromatography-mass spectrometry (LC-MS) screening method was established in order to rapidly identify the metabolites from numerous collections of Lyngbya spp. obtained from Broward and Lee County, Florida sites that may help marine ecologists assess the effects of Lyngbya spp. blooms on the environment. A link between the metabolites produced and nutrients from both the algal tissue and water column was also explored. / by Priscilla L.

Current research in natural products has heavily focused on the identification of potent biologically active compounds, specifically for drug development. The project detailed in this thesis focuses on the extraction of compounds from marine invertebrates as well as defining the absolute configuration for a compound. Utilizing marine invertebrates, the sonications method developed in this thesis provides an alternative approach to rapidly extract compounds for primary screening. This method is viable compared to a traditional overnight extraction method, without suffering compound degredation... Previously, clathric acid was isolated from an unknown Clathria sp. This compound is a bibyblic C-21 terpenoid shown to have mild antimicrobial activity against gram positive bacteria. With only its relative configuration established, additional amounts of clathric acid were required to define the overall absolute configuration. Identifying the Clathria sp. to be Clathria compressa, through spicule analysis, additional sponge tissues were then collected off the coast of Boca Raton, Florida to isolate additional quatities of clathric acid. The absolulte configuration was determined through circular dichroism and the octant rule to establish a final configuration for clathric acid's four carbon stereocenters to be: (3S, 7S, 8R, and 12S). / by Rolando Rueda de Leâon. / Thesis (M.S.)--Florida Atlantic University, 2012. / Includes bibliography. / Mode of access: World Wide Web. / System requirements: Adobe Reader.

Populations of a marine invertebrate symbiont were found on the outer surface and internal spaces of a keratose sponge from a shallow bay in the Florida Keys in May 2014. A total of 24 specimens of the seagrass and reef-dwelling sponge were collected between May 2014 and August 2015 to provide material to identify both host and symbiont, and elucidate information on the nature of the association. Based on a morphological analysis via light microscopy, histology, and scanning electron microscopy (SEM), and 99% similarity in aligned partial sequences from 28S and 18S nuclear ribosomal genes (rDNA), the symbiont was identified as the solitary entoproct Loxosomella vivipara Nielsen, 1966 (Entoprocta: Loxosomatidae). A partial sequence from the Internal Transcribed Spacer Region 2 (ITS2) of L. vivipara was registered to GenBank for the first time. The identity of the host sponge, based on a morphological investigation, is resolved as “velvet sponge” Hippospongia cf. gossypina Duchassing and Michelotti, 1864 (Demospongiae: Spongiidae). This is the first report of an entoproct commensal from Hippospongia cf. gossypina, a sponge that formerly had great commercial value when it was abundant throughout the Bahamas, Florida Keys and Gulf of Mexico. Other common sponge species at the study site were collected to investigate the host specificity of L. vivipara. Evidence that L. vivipara favorably selects the sponges Hippospongia cf. gossypina and Chondrilla nucula over other potential host sponges at the study site is provided. Commensalism is the most plausible justification for this relationship: L. vivipara is dependent on sponges for protection and food particles, while the sponges are unaffected by its presence. Further evidence of host-specific inquilinism is provided for L. vivipara associated with Hippospongia cf. gossypina, but not for L. vivipara associated with C. nucula. An inquilinistic association between an entoproct and sponge is a rare discovery only mentioned in one previous study. Sponge aquiferous qualities such as aperture and canal size, canal and choanocyte chamber arrangement, seawater pumping rate, and food particle size selection are likely factors that inhibit or enable inquilinism in sponge-entoproct associations – a potential topic for future researc / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2016. / FAU Electronic Theses and Dissertations Collection

<p>The principle aim of this study was to gain insights into the perceptions of the people living in the Cape Agulhas Area of South Africa on the issues of small-scale fishing and the historical claims to fishing rights of the communities living in the fishing villages of Struisbaai and Waenhuiskrans. A further aim was to identify the gap between knowledge and the implementation of fishing rights policies by analysing existing policies on small-scale fishing and thereby identifying possible lessons and guidelines for policy formulation. Key focus areas were the historical recollections of people, their knowledge of past, current and proposed fishing legislation and their opinions, recommendations and guidelines regarding new and proposed policies. A qualitative framework was used for this study, using key informants and the taking of life histories. The two fishing communities served as case studies and life histories were documented using semi-structured interviews. The study drew on previous research in historical practices and indigenous knowledge systems and special attention was given to scientific and archaeological research. The policy processes from 1994 to the present were described and themes were identified in the literature and the life histories. The study found that many of the methods used in earlier years is still used today, passed over from generation to generation.</p>
