"This document provides a summary of what is currently known about the science of connectivity and the techniques and tools used for measuring connectivity for different types of organisms (e.g., corals, fish and lobster). It also highlights the gaps in our knowledge and offers suggestions and advice on how to use what connectivity information is available. A strong plea is made for scientists and managers to establish close working collaborations and use management activities in an adaptive management context to simultaneously advance the scientific understanding of connectivity, while also using the best available knowledge to guide current management decisions"--P. 6.

The purpose of this symposium was to share cross-cutting research and management approaches for understanding biological connectivity in the Caribbean Sea and Gulf of Mexico and to provide a forum for resource managers and the academic community to address questions on how to apply scientific information to better manage MPAs in the region. The primary goals of the symposium were to 1): provide a forum for information-sharing and feedback between scientists conducting research on marine connectivity and resource managers who are managing resources at a local or regional scale, 2) provide hands-on training opportunities in technologies and approaches for predicting connectivity in the Caribbean region, and 3) provide a synthesis of the information available and future research recommendations on Caribbean connectivity at local and regional spatial scales.

Marine connectivity is the transfer of larvae and/or individuals between distant marine habitats. Thanks to connectivity, distant marine population can face habitat pressure by relying on the transfer from distant populations of the same species. The transfer between distant populations in the ocean is made possible by the transport due to the currents. However, it is still not clear if the current field totally determines the persistence of the marine species or if the local demography plays a role. Crucially, in situ measurements of connectivity are extremely difficult. Therefore, our knowledge about connectivity is inferred from numerical dispersal simulations. The aim of this thesis is to clarify if we can deduce the persistence from the knowledge of the current field and to investigate the effect of numerical turbulence parameterizations in estimating connectivity. Firstly, I compare graph theory and metapopulation model to determine if currents have a predominant role. This allows to identify which graph theory measures reliably identifies reproductive sites important for persistence by relying on the knowledge of currents only. Secondly, I investigate the advantages and shortcomings of different turbulence closure models. This allows to clarify which TCS better reproduces turbulence activity in numerical models. Thirdly, I investigate generating mechanisms of bottom boundary turbulence. This allows to know the effective drag coefficient due to flow over rough topography and better estimate turbulent fluxes.

Mangrove forests, seagrass beds, and coral reefs are circumtropical ecosystems that are highly productive, and provide many important biological functions and economic services. These ecosystems cover large surface areas in the shallow tropical coastal seascape but have suffered from serious human degradation, especially in the last few decades. Part of their diversity, productivity, and functioning seems to be based on their juxtaposition. Especially in the last decade significant advances have been made on new insights into their ecological connectivity. This authoritative book provides a first-time comprehensive review of the major ecological interactions across tropical marine ecosystems that result from the mutual exchange of nutrients, organic matter, fish, and crustaceans. A group of leading authors from around the world reviews the patterns and underlying mechanisms of important biogeochemical and biological linkages among tropical coastal ecosystems in 15 chapters. Included are chapters that review cutting-edge tools to study and quantify these linkages, the importance of such linkages for fisheries, and how tropical ecosystems should be conserved and managed for sustainable use by future generations. The book uses examples from all over the world and provides an up-to-date review of the latest published literature. This book is a ‘must read’ for professionals working on the conservation, management, and ecology of mangrove, seagrass and coral reef ecosystems.

One of the biggest threats to the survival of many plant and animal species is the destruction or fragmentation of their natural habitats. The conservation of landscape connections, where animals, plants, and ecological processes can move freely from one habitat to another, is therefore an essential part of any new conservation or environmental protection plan. In practice, however, maintaining, creating, and protecting connectivity in our increasingly dissected world is a daunting challenge. This fascinating volume provides a synthesis on the current status and literature of connectivity conservation research and implementation. It shows the challenges involved in applying existing knowledge to real-world examples and highlights areas in need of further study. Containing contributions from leading scientists and practitioners, this topical and thought-provoking volume will be essential reading for graduate students, researchers, and practitioners working in conservation biology and natural resource management.

Large-scale connectivity conservation initiatives are increasing in prevalence as a variety of benefits are continually being demonstrated through these models, such as establishing and strengthening marine protected area (MPA) networks. The historical approach to solely establishing protected areas (PA) is no longer sufficient for achieving effective protection and often does not include comprehensive and holistic management plans involving multiple perspectives. This thesis presents findings from research in the Dominican Republic (DR) where numerous components of coastal and marine social-ecological systems are addressed, including: status of large scale connectivity initiatives; governance structure inclusion of local resource users; and explore alternative livelihood opportunities. Data was acquired by conducting 35 key informant interviews achieved via snowball sampling with multi-scalar and cross sectoral coastal and marine stakeholders, ranging from the community level to high levels of government in the DR. After conducting interviews and evaluation of current and future large-scale marine conservation initiatives in the DR, current limitations and future opportunities for natural resource management were identified. The trend of ineffective small scale initiatives indicate that the management of individual parks or conservation projects need to be functioning smoothly (i.e. using best practices) prior to establishing larger scale conservation initiatives. Furthermore, there is ample opportunity for multiple sectors to be involved to aid the transition from extractive livelihoods in the Dominican Republic, such as destructive fishing practices, towards low impact and environmentally responsible opportunities. Findings from this study contribute to further understanding complex coastal systems, while considering management implications on local communities and ecosystems in the Dominican Republic. Recommendations from the research support a diverse governance structure of stakeholders from across sectors and multiple scales within the DR coastal and marine sector, to ensure priorities from all types of resource users are included in conservation management initiatives. Implications of this study further support the shift to inclusive governance frameworks that may contribute to increased compliance in the case of protected area legislations, boundaries knowledge, understanding local environmental challenges, and stewardship for coastal and marine resources. All these aspects help provide the appropriate institutional framework to ensure social connectivity, and ultimately assist the integration of local communities into a more sustainable and healthy relationship with nature.
