L'impact anthropique sur les écosystèmes coralliens est aujourd'hui largement documenté, que ce soit sur la biodiversité qu'ils hébergent, leur diversité fonctionnelle, les services écosystémiques qu'ils procurent ou leur capacité de résilience. Parmi les groupes trophiques, les prédateurs apicaux en général et les requins en particulier, sont particulièrement sensibles aux perturbations d’origine humaine du fait de leurs traits d'histoire de vie conservateurs (e.g. croissance lente, maturité sexuelle tardive, faible fécondité). D'après certaines estimations, les populations de requins ont décliné de plus de 90% à l'échelle globale. Afin d'assurer le maintien de leurs populations et de leur rôle fonctionnel dans la communauté, il est nécessaire de mettre en place des mesures de gestion adaptées. Les objectifs de cette thèse sont de 1) faire le bilan des populations de requins de Nouvelle-Calédonie ; 2) déterminer l'efficacité des vidéos stéréoscopiques appâtées (S-BRUVS) pour recenser les requins en les comparant aux comptages en plongées (UVC) et évaluer leur possible amélioration ; 3) évaluer l'impact de la proximité humaine sur la diversité, l'abondance et le comportement des requins récifaux et 4) déterminer l'efficacité des mesures de gestion en place pour protéger ces espèces emblématiques. Les résultats des deux méthodes de recensement montrent un important déclin d'environ 90% des abondances de requins récifaux le long d'un gradient anthropique complet en Nouvelle-Calédonie alors que la pêche des requins est historiquement absente dans cet archipel. Une importante altération comportementale du requin gris de récif (Carcharhinus amblyrhynchos) face à la nouveauté d'un appât a été mise en évidence. Les individus se tiennent plus éloigné du dispositif, interagissent moins avec l'appât et mettent plus de temps pour le mordre avec l'augmentation de la proximité humaine. Cette dernière est le principal moteur de ce déclin d’abondance (46 à 71%) et de l'altération comportementale vers des individus plus craintifs (50 à 80%). Globalement, les aires marines protégées de Nouvelle-Calédonie ne sont pas efficaces pour la protection des requins. Néanmoins, la réserve intégrale Merlet héberge des populations de requins proche du niveau de récifs isolés de l’archipel et protège une partie du comportement. Les résultats de ce travail révèlent 1) l'importance et le caractère unique des récifs coralliens isolés ; 2) qu'en absence de pêche la proximité humaine conditionne l'abondance et le comportement des requins de récifs avec des conséquences écologiques potentielles sur l'ensemble du réseau trophique ; 3) que l'efficacité des AMPs réside dans leur capacité à exclure la présence humaine sur une surface suffisamment grande. / Anthropogenic impacts on coral reefs are largely documented through changes in functional diversity, ecosystem services or resilience. Among trophic groups, apex predators in general and sharks in particular are the most sensitive to disturbance due to conservative life history traits (e.g. slow growth, late sexual maturity, low fecundity). By some estimates, shark populations have declined by >90% worldwide. To ensure the sustainability of their populations and their functional role in the reef community, appropriate management measures must be implemented. The aims of this thesis are 1) to assess reef shark populations in New Caledonia; 2) to evaluate the efficiency of stereo baited remote underwater video systems (S-BRUVS) in surveying shark distribution comparing them to underwater visual censuses (UVC) and to evaluate their potential improvements ; 3) to evaluate the impact of human proximity on diversity, abundance and behaviour of reef sharks and 4) to determine the efficiency of management measures currently in place in New Caledonia to protect reef shark populations. The results of S-BRUVS and UVC were congruent and revealed a dramatic decline of shark abundance of ~90% along the anthropogenic gradient in a country where shark fishing is historically absent. An important behavioural alteration of the grey reef shark (Carcharhinus amblyrhynchos) towards bait was highlighted. Individuals remained farther from the device, exhibited more cautious approaches, interacted less with the bait and took longer to bite it as human proximity increased. Human proximity was the main driver of the abundance decline (46 to 71%) and the behavioural alteration towards shier individuals (50 to 80%). Globally, MPAs in New Caledonia are not effective in protecting reef sharks. However, the oldest and most restrictive MPA (Merlet) hosts shark abundance close to that of some remote reefs of the archipelago and partially protect the behaviour of individuals. These results 1) emphasize the unique role of remote coral reefs as the last refuges for sharks ; 2) reveal that in absence of shark fishing, human proximity condition shark abundance and behaviour with potential ecological consequences and 3) indicate that the MPAs efficiency to ensure the protection of reef sharks is effected by their ability to exclude human presence over a sufficiently large area.

Por isso, é necessária a busca por alternativas de baixo custo que possam auxiliar nessas questões. A abordagem por biótopos associada à ciência cidadã mostra-se adequada para o monitoramento de comunidades marinhas bentônicas por possibilitar extensa amostragem em curto período de tempo e com baixo custo, além de integrar cidadãos ativamente em produções de conhecimento. Essa pode ser uma ferramenta interessante para o monitoramento de UCs marinhas; porém, é importante que a elaboração do protocolo de monitoramento e sua validação sejam realizadas considerando-se as recomendações da literatura. Nesse sentido, este trabalho se propôs a (1) avaliar o status dos protocolos de ciência cidadã para bentos marinho e costeiro no mundo e (2) a propor, aplicar e validar o uso da ciência cidadã associada à abordagem por biótopos como uma ferramenta para o monitoramento de comunidades bentônicas em UCs marinhas. Para isso, realizamos o levantamento e comparação da estrutura de protocolos de ciência cidadã para bentos costeiro e marinho, incluindo o protocolo proposto no presente estudo. Apesar da maioria dos projetos encontrados apresentarem várias das características recomendadas pela literatura, seus principais interesses são a coleta de dados e os resultados oriundos destes, ficando a educação dos CCs, sua inclusão no processo de desenvolvimento do protocolo e sua avaliação em segundo plano. Sugerimos que os protocolos considerem a educação científica e ambiental dos CCs como um objetivo a ser atingido, e nosso protocolo leva tais ideias em consideração. Para embasar a elaboração do nosso protocolo, realizamos um levantamento prévio dos biótopos de um trecho do infralitoral consolidado da Ilha das Palmas (Estação Ecológica Tupinambás, Ubatuba/SP). Nesse levantamento, foram identificados 20 biótopos e três animais vágeis associados em apenas um mergulho. Também foram detectados organismos invasores e a dominância de tapetes na área de estudo. Isso é um demonstrativo de que a caracterização de comunidades marinhas bentônicas utilizando o método visual por biótopos pode agilizar a identificação de possíveis impactos negativos e a realização de planos de prevenção ou mitigação dos mesmos. Cientistas cidadãos (CCs) voluntários foram capacitados no uso do protocolo, que foi dividido em duas etapas: (1) a coleta de dados, que consistiu de registros fotográficos padronizados do costão rochoso; e (2) o processamento das fotografias, que consistiu da identificação (ID) dos biótopos nas fotos em um curso presencial. As fotos obtidas durante a Etapa 1 estão disponíveis na plataforma Zooniverse, através do projeto Monitore Tupinambás (https://www.zooniverse.org/projects/larissakawabe/monitore-tupinambas), no qual qualquer voluntário pode contribuir com as análises, seguindo o tutorial disponível. A avaliação educacional da pesquisa, realizada através de questionários pré e pós-atividade, mostrou principalmente que houve mudanças de percepção dos CCs em relação ao ambiente estudado. Para a validação dos dados da Etapa 2, comparamos as IDs dos biótopos realizadas pelas pesquisadoras (grupo controle) e CCs (grupo experimental), analisando a precisão e acurácia das respostas. Apesar das limitações inerentes do método utilizado (ID por foto) e das necessidades de modificação do protocolo identificadas por CCs e pesquisadoras; os resultados de acurácia e precisão foram comparáveis aos de outros trabalhos similares, demonstrando que esse protocolo, o primeiro a ser desenvolvido com foco em bentos marinho no Brasil, é uma ferramenta promissora para o monitoramento participativo e de longo prazo das UCs marinhas do país, auxiliando na gestão dessas áreas e na educação ambiental e científica dos cidadãos participantes. / Despite the importance of monitoring the marine protected areas (MPAs), logistical and budgetary problems make it difficult to carry out and, consequently, affect the effective management of these areas. Therefore, it is necessary to search for low-cost alternatives that could help with these issues. The biotope approach associated with citizen science could be interesting for the monitoring of marine benthic communities because it allows extensive sampling in a relatively short period of time and at low cost. At the same time, citizens are integrated as active contributors in the knowledge production. This can be an interesting tool for the MPA monitoring; however, it is important that the elaboration of the monitoring protocol and its validation consider the literature recommendations. In this sense, this work aimed to (1) evaluate the status of citizen science protocols for marine and coastal benthos in the world and (2) to propose, apply and validate the use of citizen science associated with the biotope approach as a tool for monitoring benthic communities in MPAs. For this, we conducted a survey and comparison of the structure of citizen science protocols for coastal and marine benthos, including the protocol proposed in the present study. Although most of the projects found present several of the characteristics recommended by the literature, their main interests are the data collection and their results, being the education of citizen scientists, their inclusion in the protocol development process and their evaluation in the background. We suggest that the protocols consider the scientific and environmental education of citizen scientists as a goal to be achieved, and our protocol takes such ideas into account. To support the elaboration of our protocol, we carried out a preliminary biotopes survey of a consolidated subtidal section of the Ilha das Palmas (Tupinambás Ecological Station, Ubatuba/SP). In this survey, 20 biotopes and three associated animals were identified in only one dive. Invasive organisms and carpet dominance were also detected in the study area. This is a demonstration that the benthic marine communities characterization using the biotope visual method can speed up the identification of possible negative impacts and the implementation of prevention or mitigation plans. Volunteer citizen scientists were trained in the use of the protocol, which was divided into two steps: (1) data collection, which consisted of standardized photographic records of the rocky reef; and (2) the processing of the photographs, which consisted of identification (ID) of the biotopes in the photos in a classroom course. The photos obtained during Stage 1 are available on the Zooniverse platform through the Monitore Tupinambás project (https://www.zooniverse.org/projects/larissakawabe/monitore-tupinambas), in which any volunteer can contribute to the analyzes, following the tutorial available. The educational evaluation of the research, performed through pre and post-activity questionnaires, showed mainly that there were changes in perception of citizen scientists in relation to the studied environment. For the data validation of Stage 2, we compared the biotope IDs performed by the researchers (control group) and citizen scientists (experimental group), analyzing their accuracy and precision. Despite the inherent limitations of the method used (ID per photo) and the identification by citizen scientists and researchers of protocol modification needs; the results of accuracy and precision were comparable to those of other similar studies, demonstrating that this protocol, the first developed with a focus on marine benthos in Brazil, is a promising tool for the participatory and long-term monitoring of the country's MPA, assisting in the management of these areas and in the environmental and scientific education of the citizens scientists.

Thesis (MScConEcol)--UnStellenbosch University, 2011. / ENGLISH ABSTRACT: The privilege of utilising resources from the globe's marine ecosystems is threatened. Adequate regional and global conservation efforts are vital. Understanding species' distributions and the environmental variables influencing community structures are important for instigating optimum conservation plans. A major threat facing marine ecosystems is the introduction and proliferation of alien invasive species. The distribution and geographical expansion of marine alien invasive species, along with environmental variables driving their increase is also critical for drawing up conservation plans. In response to this point, this study addresses gaps in our knowledge regarding intertidal marine invertebrate species distributions particularly that of marine alien species in the Kogelberg Biosphere Reserve (KBR) and adjacent Betty's Bay Marine Protected Area (MPA) in the Western Cape of South Africa, a prime area for south-coast marine conservation. Species identifications were done in September 2010. Two marine alien invertebrate species were identified along the coastline. These were the invasive mytilid Mediterranean mussel Mytilus galloprovincialis and the bryozoan Watersipora subtorquata. A quantitative systematic survey of the intertidal region, consisting of seven rocky shore sites was then undertaken from October 2010 to December 2010. The abundance of all focal marine invertebrate species, within six selected habitat types was assessed. Environmental variables were also recorded. Statistical tests were done to investigate for significant interaction in mean abundance and mean species richness among intertidal zones and protection status (MPA and non-MPA), and among intertidal sampling units (SU‟s) and protection status. There was also investigated for significant difference in mean abundance and mean species richness across intertidal zones and habitat types where protection status was not taken into account, and to test for significant differences in mean abundance and mean species richness between the intertidal zones and habitat types. Correspondence analyses were used to illustrate relationships between species composition and the defined environmental variables. Tests were done to investigate for significant differences in mean abundance of the identified marine alien species between the MPA and non-MPA, study sites, SU's, and wave exposures. These results indicated that vertical and horizontal stress gradients along the shore mainly influence abundance and species richness. The significantly higher abundance of M. galloprovincialis outside the MPA is due to its preference for wave-exposed areas. The reason for the difference in the total abundance of W. subtorquata in the different habitats is not clear, although it appears that the higher abundance of this species in the MPA is because the sheltered nature of the MPA. M. galloprovincilais displaces indigenous species. W. subtorquata does not cause any significant harm along the coast of South Africa. This study indicates that the abundance of M. galloprovincialis and W. subtorquata in the MPA is relatively low. The MPA is therefore in good condition with regards to intertidal alien species. It is important that the MPA and adjacent KBR's coastline maintain its current pristine status. / AFRIKAANSE OPSOMMING: Die voorreg om mariene hulpbronne te benut, word bedreig. Voldoende nasionale en globale mariene bewaring is krities. 'n Deeglike kennis van spesies verspreiding en omgewingsveranderlikes wat gemeenskapstrukture beïnvloed is noodsaaklik vir optimale bewaringspogings. Mariene indringerspesies en verspreiding van indringerspesies bedreig mariene ekosisteme. Dit is belangrik om basiese kennis in te win oor die geografiese verspreiding van indringerspesies saam met die omgewingsveranderlikes wat hierdie verspreiding beïnvloed. Hierdie studie fokus dus daarop om die kennis met betrekking tot intergety ongewerwelde spesiesverspreiding, veral dié wat uitheems is langs die kus van die Kogelberg Biosfeer Reservaat (KBR) en aangrensende Bettys Baai Mariene Beskermde Gebied (MBG) in die Wes-Kaap in Suid-Afrika uit te brei. Hierdie streek word beskou as gesog vir mariene bewaring in Suid-Afrika. Identifikasie van spesies is in September 2010 gedoen. Twee intergety uitheemse ongewerwelde spesies is langs die kus geïdentifiseer; die indringer 'mytilid' Mediterreense mossel - Mytilus galloprovincialis en die 'bryozoa' Watersipora subtorquata. 'n Kwantitatiewe sistematiese oorsig van die intergety rotsagtige streek, bestaande uit sewe lokaliteite, is gedoen. Steekproefneming is vanaf Oktober 2010 tot Desember 2010 uitgevoer. Alle fokale intergety ongewerwelde spesies, in ses geselekteerde habitattipes is getel. Omgewingsveranderlikes is aangeteken. Daar is statisties getoets vir verskille in die talrykheid en spesiesrykheid tussen die intergety zones en beskermingsstatus (MBG en nie-MBG), en tussen die intergety habitattipes en beskermingsstatus. Daar is ook getoets vir verskille in talrykheid en spesiesrykheid tussen die intergety zones en habitattipes waar beskermingsstatus nie in ag geneem is nie. Ooreenstemmende analises is gedoen om die verhoudings tussen die spesiesamestelling en die gedefinieerde omgewingsveranderlikes te illustreer. Daar is statisties getoets vir verskille in die talrykheid van die geïdentifiseerde uitheemse spesies tussen die MBG en nie-MBG, die verskillende lokaliteite, die verskillende habitattipes en tussen die verskillende golf blootstellings. Hierdie studie dui aan dat vertikale en horisontale stresgradiënte die hoofoorsaak is wat talrykheid en spesiesrykheid beïnvloed. Die aansienlik hoër talrykheid van M. galloprovincialis buite die MBG is van die gebied se hoër golfblootstelling. Die beduidende verskil in talrykheid van W. subtorquata is onduidelik. Dit kan egter afgelei word dat die beskutte aard van die MBG 'n rol speel by die aansienlik hoër talrykheid van hierdie spesie binne die MBG. M. galloprovicialis verplaas inheemse spesies. Geen beskikbare bewys dui daarop dat W. subtorquata enige beduidende skade langs die kus van Suid-Afrika aanrig nie. Die lae talrykheid van beide hierdie spesies binne die MBG dui daarop dat hierdie unieke area steeds in goeie toestand ten opsigte van intergety uitheemse spesies is. Dit is noodsaaklik dat die huidige status van die MBG en aangrensende kuslyn gehandhaaf word.

This PhD thesis in environmental science aims to contribute to the theoretical and empirical understanding of the relation between participation and legitimacy in multi-level environmental governance. It is widely assumed that actor involvement has great potential to improve the legitimacy of nature conservation through long-term acceptance and target achievement. However, local resource conflicts problematize the way a relation between participation and legitimacy is depicted on other administrative levels. Studies exploring the effect that participation has on legitimacy are relatively rare, especially in multi-level arrangements of coastal conservation. In this thesis the relation between participation and legitimacy on the local level is examined, as well as how this relation is conditioned by multi-level governance and power. The relation is empirical studied with two local implementation processes of the Helsinki Convention’s network of marine protected areas (HELCOM MPAs). The cases are located in Sweden. Sweden and the Baltic Sea region are in the forefront of participation in nature conservation, and therefore act as a strong case for the exploration of institutional participation. However, despite apparent political will and international support, the efficiency of actor involvement for nature conservation has been questioned, also for the HELCOM MPA and especially on the local level. Based on the results of this study, I question the assumption that weak legitimacy predominantly is an issue of insufficient information sharing. The findings show that involving actors to legitimize the adoption of strict adherence to a pre-established model of conservation likely fails to create long term support for conservation. Instead, relocation of power to the affected actors seems essential in order to make participation establish legitimacy. It appears important to create room for local influence in the design, management and implementation of a particular conservation area in the particular place/context. In both examined cases, there are elements of participation that support legitimacy, for example the development of a shared vision. There are also elements that hamper legitimacy, such as, for example, the high expectations different actors have on participation to reach consensus on protective values. These unmet expectations seem to fuel conflicts of interests among actors on different levels. / Världens hav är i kris. Med ett stort internationellt tryck för att skydda dem har den svenska regeringen satt ambitiösa mål för etablering av marina reservat. Beslutsfattare och forskare har höga förväntningar på att lokalt deltagande underlättar etableringen. Men utan verkliga möjligheter för lokalt deltagande att påverka besluten så verkar förväntningarna orealistiska, med allvarliga konsekvenser för legitimitet av miljöskydd. Avhandlingen undersöker relationen mellan deltagande och legitimitet i svensk östersjöförvaltning genom att studera samrådsprocesserna för Gräsö marina naturreservat och St Anna-Missjö marina skyddsområde. Studien visar på både positiva och negativa samband mellan deltagande och legitimitet, beroende på kvalitén av deltagande. Olika lokala aktörer är djupt engagerade i resursfrågor och vill ha möjlighet att diskutera dessa med staten. Lokala aktörer uttrycker besvikelse och frustration om samråden har en begränsad inverkan på faktiska beslut. Besvikelsen kan underminera stödet för naturskydd och försämra relationen mellan stat och lokala aktörer i längden. I ett av de undersökta fallen var de lokala aktörerna engagerade i att formulera en gemensam vision för området tillsammans med myndigheterna, något som annars är ovanligt. Det visade sig ha en mycket positiv effekt på samrådsprocessen och legitimiteten av naturskyddet.

Cette recherche a porté sur quelques enjeux importants liés à la gestion des aires marines protégées (AMP) en Indonésie en examinant comment celles-ci sont en mesure d'adapter leurs politiques afin de mieux répondre à l'évolution des conditions socioéconomiques et écologiques, quels ont été les impacts socioéconomiques de ces aires, et quelles sont les préoccupations environnementales des acteurs locaux dont les moyens de subsistance dépendent des ressources règlementées. Le «livelihoods framework » a servi de guide pour notre analyse des changements socioéconomiques dans la région, tandis que la notion d’« environmentality » d’Agrawal a fourni les bases théoriques pour l'examen de la formation de sujets environnementaux au parc national de Karimunjawa. Cette étude a montré que les changements de politique apportés au plan de la gestion du parc sont un pas dans la bonne direction, mais que les objectifs importants liés sa cogestion n'ont jamais été entièrement réalisés dans la pratique. Les résultats montrent également que d'importants changements socioéconomiques surviennent dans le parc, de nombreux pêcheurs se tournent vers des moyens de subsistance alternatifs, afin de compenser la baisse des prises de poissons. Enfin, cette étude a révélé que d'importants changements positifs dans les préoccupations environnementales sont survenus depuis la modification du zonage du parc, mais que ceux-ci ne se sont pas entièrement traduits en conformité avec les règles et règlements de l'AMP. / This research examined a few important issues related to marine protected area (MPA) management in Indonesia by looking at how MPAs are able to adapt their policies in order to better suit evolving socioeconomic and ecological conditions, what socioeconomic impacts have been felt as a result of MPA implementation, and what are the environmental subjectivities of local actors whose livelihoods are dependent on the resources that are being regulated. The livelihoods framework served as a guide when examining local socioeconomic changes in the region, while Agrawal’s concept of environmentality provided the theoretical underpinnings when examining the formation of environmental subjects in Karimunjawa National Park. This study found that the policy changes brought about in KNP’s reworked management plan are a step in the right direction, but that important goals related to park co-management were never fully realized in practice. The results also show that significant socioeconomic changes are occurring within the park, with many fishermen turning to alternative livelihoods in order to offset declining fish catches. Lastly, this study uncovered that significant positive shifts in environmental subjectivities have occurred since the re-zoning of the park, but that these have not fully translated into compliance towards the rules and regulations of the MPA.

<p>Effective conservation strategies for sea turtles require knowledge of animal movements and protection of biologically important habitats and life history stages. For breeding adult sea turtles, understanding both their inshore and pelagic spatial patterns is imperative to the successful protection of the species and the accurate identification of their vulnerabilities. This study provides insight into the inter-nesting, post-nesting, and foraging movements of green sea turtles (<i>Chelonia mydas</i>) that nest on Bioko Island, Equatorial Guinea, by using satellite telemetry to track green turtles (n=12) during two nesting seasons (2017-18, 2018-19), and as they migrated to foraging grounds after the nesting season. These tracks were fit with a switching state space model to characterize movements, and then analyzed in relation to environmental and anthropogenic factors. Dive depth data was also used to determine utilization patterns within the water column. The 12 tagged turtles migrated for an average of 1064 km to two distinct foraging grounds, with 10 migrating west for an average of 1115 km to the coastal waters of Ghana, and 2 migrating south for an average of 1563 km to the coastal waters of Angola. Migrating turtles used both direct, pelagic migration strategies, and biphasal, coastal strategies, which included intermittent foraging throughout migrations. Dive depths varied depending on behavior, with an average of 19.3 m during inter-nesting, 12.6 m during migration and 8.5 m during foraging. Knowledge of inter-nesting habitat use, migration patterns, and foraging ground locations will be critical for the development of marine conservation management plans in the Gulf of Guinea and aide in sea turtle conservation efforts throughout the area. Additionally, spatial and dive depth data can inform zonal fishing regulators and provide information needed for modifications to fishing practices and gear that is most likely to reduce sea turtle bycatch. These data will provide a more complete understanding of marine areas critical to sea turtle conservation and aide in sustainable economic development in the Gulf of Guinea.</p><br>

Species distribution maps can provide important information to focus conservation efforts and enable spatial management of human activities. Two sympatric marine predators, grey seals (Halichoerus grypus) and harbour seals (Phoca vitulina), have overlapping ranges but contrasting population dynamics around the UK; whilst grey seals have generally increased, harbour seals have shown significant regional declines. A robust analytical methodology was developed to produce maps of grey and harbour seal usage estimates with corresponding uncertainty, and scales of spatial partitioning between the species were found. Throughout their range, both grey and harbour seals spend the majority of their time within 50 km of the coast. The scalability of the analytical approach was enhanced and environmental information to enable spatial predictions was included. The resultant maps have been applied to inform consent and licensing of marine renewable developments of wind farms and tidal turbines. For harbour seals around Orkney, northern Scotland, distance from haul out, proportion of sand in seabed sediment, and annual mean power were important predictors of space-use. Utilising seal usage maps, a framework was produced to allow shipping noise, an important marine anthropogenic stressor, to be explicitly incorporated into spatial planning. Potentially sensitive areas were identified through quantifying risk of exposure of shipping traffic to marine species. Individual noise exposure was predicted with associated uncertainty in an area with varying rates of co-occurrence. Across the UK, spatial overlap was highest within 50 km of the coast, close to seal haul outs. Areas identified with high risk of exposure included 11 Special Areas of Conservation (from a possible 25). Risk to harbour seal populations was highest, affecting half of all SACs associated with the species. For 20 of 28 animals in the acoustic exposure study, 95% CI for M-weighted cumulative Sound Exposure Levels had upper bounds above levels known to induce Temporary Threshold Shift. Predictions of broadband received sound pressure levels were underestimated on average by 0.7 dB re 1μPa (± 3.3). An analytical methodology was derived to allow ecological maps to be quantitatively compared. The Structural Similarity (SSIM) index was enhanced to incorporate uncertainty from underlying spatial models, and a software algorithm was developed to correct for internal edge effects so that loss of spatial information from the map comparison was limited. The application of the approach was demonstrated using a case study of sperm whales (Physeter macrocephalus, Linneaus 1758) in the Mediterranean Sea to identify areas where local-scale differences in space-use between groups and singleton whales occurred. SSIM is applicable to a broad range of spatial ecological data, providing a novel tool for map comparison.

As competing uses of our coastlines increase, natural resource agencies are employing marine spatial planning (MSP) to designate areas for different uses or activities in order to reduce conflicts while achieving ecological, economic and social objectives. A central challenge of implementing MSP is development of a rigorous approach for analyzing tradeoffs across the provision of ecosystem services (i.e., the benefits humans receive from nature). This study develops an operational approach to this problem that is founded on community-based methods, ecological production theory, and multi-criteria decision analysis (MCDA). The approach merges ecological models with surveys to identify marine ecosystem services for use in tradeoff analysis. The approach allows for a single set of marine ecosystem services to at once be valued by local stakeholders and measured by biologists, thus connecting social and biological monitoring efforts. To develop the approach in a real-world context, I examined ecosystem services associated with nearshore marine ecosystems in Oregon, where marine reserves are being introduced for biodiversity conservation. I worked with stakeholder focus groups in three Oregon communities to identify 24 marine ecosystem services. I then linked the ecosystem services with ecological indicators, which I then consolidated to derive 11 items for use in a survey-based tradeoff analysis exercise. I administered the survey to a nonrandom sample of stakeholders in Oregon (n=31), from which their relative preferences and preference weights for ecosystem services were derived. The weights and preference measures may then be used in MSP decision-making. Furthermore, I grouped the stakeholder survey data in three ways: by location of residence (coastal vs. non-coastal), by eight categories of affiliation (e.g., business owners, conservationists, commercial and recreational fishers, etc.), and by resource use patterns. I then analyzed the various groupings of stakeholders for within- and between-group homogeneity of preferences. Results of the analyses showed that there are statistically significant variations in preferences within and between most groupings. Capturing the variations in stakeholder preferences is important when developing policies that affect different stakeholder groups. Thus, when implementing the survey instrument, I suggest random sampling of stakeholders stratified by location, affiliation, and resource use. This study provides one of the first examples of a systems-based approach to ecosystem service valuation operationalized to inform MSP, and novel features of the approach have a number of implications for advancing marine research and management. First, by using stakeholders to identify ecosystem services, the approach allows for a tailored implementation of ecosystem-based management at the community level. Second, by integrating ecological and economic information on the provision and value of ecosystem services, the approach provides relevant data for MSP decision-making during the siting, evaluation, and monitoring stages. And third, by applying both stated-preference and MCDA methods, the approach may capture the array of values represented by diverse stakeholder groups. / Graduation date: 2013
