Mangroves, fisheries and community livelihoods
Mangroves are thought to provide vital ecosystem services to coastal fishing communities through the enhancement of fisheries production. Ongoing loss of mangrove extent globally is therefore of societal concern given that communities living near mangroves rely on mangrove-fishing for income and …

L’élevage de la crevette : une menace pour les mangroves?
… biens et de ses services. Malheureusement, les mangroves subissent une dégradation continuelle provenant de diverses sources anthropiques et naturelles. Plus précisément, une menace inquiétante s’est matérialisée vers la fin des années 60, soit l’élevage de la crevette, qui est actuellement la …

Mangroves, fisheries and coastal communities’ perception of environmental change
… and communities at risk. In this thesis, mangroves are used as an ecosystem of reference (described in Chapter 2) to examine the relationship between coastal communities and their surrounding environment, emphasising their vulnerable dependence on fragile ecosystems. Fieldwork from two …

Development of a Mangrove Quality Index in Tampa Bay, Florida
Mangroves are an important resource. They provide a breeding ground for commercially and recreationally important fish, protect shorelines from erosion and improve coastal water quality. Historically, mangroves were undervalued, leading to a loss of 35% of mangroves worldwide and 44% in Tampa Bay …

The evolution of tidal coastal landscapes and the controls on pathways to equilibrium
… observation of an estuarine shoal covered with mangroves, and a calibrated and validated model with field data in order to explore how different components of tidal environments influence the short and long-term dynamics of tidal lagoons. The idealised modelling specifically focused on the roles …

Understanding changes in mangrove forests and the implications to community livelihood and resource management in Kenya
… disregards local people's needs. Degraded mangroves are more vulnerable to environmental changes and may be less able to provide the ecosystem services and goods that are crucial to the livelihood of local people. The key outcome of sustainable resource management is to identify ways to …

Is The Exotic Brazilian Pepper, Schinus Terebinthifolius, A Threat To Mangrove Ecosystems In Florida?
… Lagoon alongside three native species of mangroves, Rhizophora mangle, Avicennia germinans and Laguncularia racemosa. The purpose of my study was to evaluate competition between the invasive S. terebinthifolius and these three native species of mangroves in the coastal estuarine system …

The physical and ecological impacts of mangrove expansion and mangrove removal: Tauranga Harbour, New Zealand
… field measurements of plant physiognomy of the mangroves within Welcome Bay, Waikareao Estuary and Waikaraka Estuary identified a limited vertical growth of < 10 cm per year, resulting in mean plant heights < 1.5 m. The climatic conditions limiting plant growth appeared to also limit the …

Projections of Mangrove, Saltmarsh, and Oyster Reef Viability in the US East Coast and their Role in Coastal Defense
… utility in the whole region. In general, mangroves’ ranges extend polewards as temperatures increase while saltmarsh and oyster reef ranges remain unchanged. Additionally, mangroves and saltmarshes suffer from coastal squeeze as sea levels rise. Next, I used a similar methodology to the …

The Mangrove Mosaic: An Ecological Landscape Design Strategy for Everglades City's Climate Adaptation and Phased Transition Amidst Sea-level Rise
… ways to enhance the unique capabilities of mangroves, an action plan was implemented in Everglades City, Florida, chosen as a focused site. Located at the intersection of major ecological reserves and facing serious threats from significantly higher sea level rise, Everglades City presents …

Functional connectivity of coral reef fishes in a tropical seascape assessed by compound-specific stable isotope analyses
… integrity of tropical habitats, including mangroves, seagrass beds and coral reefs, is coming under increasing pressure from human activities. Many coral reef fish species are thought to use mangroves and seagrass beds as juvenile nurseries before migrating to coral reefs as adults. …

Carbon Sequestration in Tidal Salt Marshes and Mangrove Ecosystems
… from 0.4 to 8.9 Pg C. Tidal salt marshes and mangroves store a large amount of carbon in their soils, which was estimated in the range of 0.02 to 4.9 Pg C. Moreover, the estimates of carbon storage in mangrove biomass ranged between 1.22 to 4.98 Pg C, and from 0.007 to 0.02 Pg C in tidal marsh …

A Comparative Analysis of Plastic Pollution Distribution in Costa del Este in Panama and Central American countries: Belize, Colombia, Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua
Mangroves are essential for coastal communities' economies and ecological services, including shoreline protection, preventing erosion, and water filtration. However, pollution poses a significant threat. My study investigated the impacts of marine plastics, mangrove conservation practices, and …
