Taking a Look at Mangroves

Mangroves are halophyte plants that are physiologically amended to survive in habitat containing high concentration of salt in the soil water even though salt is not a physical requirement for growth; hence they are facultative halophytes (Dictionary, 2015). Mangroves at Nudgee Beach have developed three special mechanisms to manage the excess salt levels in their environment due to the disability of enzymes function at high salt concentration. Each species of mangroves are able to either: exclude (prevent salt entering), extrude (take salt out) or accumulate large amounts sodium chloride, enabling them to survive in their ecosystem (University of Sydney, 2015). Some species of mangrove have more than one of the above characteristics. The process

Mangroves are woody trees and shrubs with a thick, exposed network of roots that grow down from the branches and into the water and sediment. All mangroves are found on the intertidal zones between ocean and the land. When the sediment accumulate little wave occurs, the saline depend on the frequency. Some of the indirect impacts are the sediment runoff and also including chemical runoff, global warming is one of main effects of the mangrove ecosystem. In Tannum there are various types of mangroves. Such as the river and grey mangroves located at south tree and wild cattle in both Tannum sands and Boyne Island along the Boyne River. Leaves are around 7cm long gland that secret salt, the

Mangrove Forest is another type of ecosystem in South Texas. Mangrove Forests are found along the coast in salty waters and the general abiotic conditions are high salinity flooded soils, low wave energy, high temperatures, and muddy soils. Black Mangrove and Buttonwood are the dominant plant species in South Texas Mangrove Forest ecosystem. Buttonwood is adapted to this ecosystem because it resides inland where there is less salty conditions. Black Mangrove is adapted to sandy salty clay soil and requires protection from wave action and they are sensitive to cold weather. Some common animal species that live in Mangrove Forests are many species of fish, crabs, mollusks, and birds. Mangrove forests provide a habitat, shelter, and nursery to these species that reside in this ecosystem. Mangrove forest serve as a coastal protection from severe storms and hurricanes also help remove pollutants and erosion. The economic importance of Mangrove forest is that they support fisheries, water purification, tourism, and coastal protection. Human activities pose a threat to Mangrove Forests because of the removal of some mangroves, boat waves, oil spills, dredging, draining, and diking.

Zonation is the distribution of animals and plants into specific zones according to abiotic factors and characterised by its dominant species [15]. Mangrove zonation is the distinguishable categorisation of a mangrove ecosystem that extends from shore to inland regions. Definitive spatial variation of mangrove species has been recognised amongst different ecosystems worldwide and is accredited as being influenced by abiotic and environmental factors [16]. In Eastern Australia, the majority of mangrove forests may be divided into landward, middle and seaward zones, based off of their placement in relation to tidal position. The following points represent the typical physiognomies characterised by mangroves in their corresponding zones:

Mangroves are trees and shrubs forming forests on the coastal wetlands, typically growing between saltmarsh and seagrass beds. Sydney Olympic park is the main habitat for the grey Mangrove and the planted river

The Tampa Bay Estuary is essentially the Tampa Bay Watershed. The energy flow and composition of the Tampa Bay Estuary is a complex system of biogeochemical process. Abiotic and Biotic factors regulate biogeochemical process in the estuary. “A food web is in essence a network model of an ecosystem that describes the trophic interactions between species” Liu, Chen, Jordán, Lin, & Wai-Jen Liu, 2010, p. 1 )The energy flow and community composition through trophic levels in the Tampa Bay Estuary bioregion is detailed in this writing assignment.

Floras and microbes are additional main biotic mechanisms of many oceanic ecosystems. Microbes act as decomposers for oceanic ecosystems, and they break defunct living matter and transforms it into vitality that is used by other existing organisms in the oceanic ecosystem. Detrivores, which are a type of animal, also eat deceased or putrefying plants and animal matter. Algae, which are autotrophs, appear as the head herbal vivacity and primary producers in oceanic ecosystems. The sunlight transforms the light into energy for nourishment for marine plants. Heat and light are focal abiotic factors discovered in essentially all oceanic ecosystems, consequently oceanic ecosystems has some broaden abiotic mechanisms, comprising viscosity and many more. The power that the bulk of an organism is called buoyancy. The durability of the drive of seawater is called viscosity. These abiotic factors source to the drive of all organisms in oceanic systems. Sunlight pierces the sea exterior only about 65 feet. As there is more salt in the Great Barrier Reef than in other oceanic ecosystems the marine holds less oxygen than the

There are many organisms living, thriving and surviving off of the mangrove forests. Mangroves are always being affected by natural and unnatural factors that create significant threats to this precious ecosystem (Mangrove Watch, 2016). The natural factors can occur seasonally, annually and periodically, with severe events including cyclones and anything else that affects all biotic (living) and abiotic (non-living)

The ocean is one of, if not, the largest biome on earth. There are more than one million species of marine life. Covering over 70 percent of the Earth’s surface, the ocean is our planet’s largest habitat, containing 99 percent of the living space on the planet. This area holds the life of nearly 50 percent of all species on Earth. Like lakes, oceans are subdivided into separate zones: intertidal, pelagic, abyssal, and benthic. All four zones have a great diversity of species. The intertidal zone is the region along the shoreline between average low tide and average high tide. In other words, this region goes through cycles of submergence and exposure to air. Animals in this zone must be able to survive the extended periods

Kelp forests are “a source of food and habitat for dozens of other coastal species” (qtd. in Soulé et al 1240). Therefore, to maintain the diversity and richness of the coastal marine ecology, kelp forests should be preserved.

The intertidal rocky shore of Caloundra Beach is inhabited by diverse range of biodiversity of animals and plants, many of which have developed high levels of adaptations throughout their existence. The very boundary of marine and terrestrial ecosystem, this environment is subjected to extremes of the physical environment such as temperature, desiccation, wave turbulence as well the ecological interactions that commonly occur in biotic communities (e.g. competition, predation). However Rocky intertidal shores are easily accessible by humans and provide an enjoyable opportunity for passive recreation and for science and environmental education as well.

The majority of untouched island is covered by jungle-like surroundings known as the mangrove, its inhabitants being deadly scorpions and snakes, roofed by the leaves under which poisonous skull-spiders shelter. The vast green mangrove covering the island surrounds a small quiet town where the few inhabitants of this unique part of the world will

Crossing the Mangrove by Maryse Condé first published in 1989, offers a fitting representation of French Caribbean history and culture. The novel stands out for its celebration of diversity and the concept of root identity throughout French Caribbean society. Condé’s novel reflects on the people living in Guadeloupe and the complex system that colonialism has created in the Caribbean. Also, it links the créolité movement from its counterpart Negritude and demonstrates how it shapes the identity of individuals living in the French Caribbean. The population of Rivière au Sel exemplifies the mixture of Guadeloupian people and how they interact with each other in a small community. Countless waves of immigrates to the Caribbean have brought African, East Indian, Europeans, Asians and other racial groups to live in close proximity to each other in Guadeloupe. In Praise of Creoleness, it explains the emergences of créolité and how it is a metaphor for a unique Caribbean identity completely separated from other movement in the Caribbean.

Seagrasses are essential primary producers that provide habitat and refuge to fauna. Anthropogenic influences have caused global loss of seagrasses and a major contributor is eutrophication, which increases phytoplankton and algal populations, reduces light availability, and causes daily hypoxic conditions. Eutrophication is commonly linked to declines in temperate conditions and is more difficult to link to tropical systems since decreases are typically related to physical damage and diminishing light conditions from runoff. Climate change, herbivore declines, disease and overfishing, along with anthropogenic impacts from coastal development, run-off, eutrophication, and aquaculture have caused declines in coral reefs and mangrove systems. These three systems are interconnected and when one system is impacted, secondary impacts are observed in the other systems; coastal ecosystems will be adversely effected and decline. Additional research, conservation, and ways to reduce anthropogenic impacts have been discussed. Restoration is used to reverse habitat loss, although success is varied. Coastal systems and the biological and ecosystem services they provide, may take decades to establish. Marine Protected Areas (MPAs) are instituted to protect systems from further degradation, restore communities and allow them to flourish naturally. However, local residents are affected by MPAs and may become displaced, have restriction placed on their livelihood, or elimination of their

On the 9th of March, I went to Siren’s Rocks to investigate the community pattern, also called zonation, within the bounds of Island Bay’s Wellington Ecological Marine Reserve. The ecosystem of Taputeranga Marine Reserve takes the full impact of the Southern ocean swells. This Reserve is influenced by three different oceanic currents. This is an abiotic factor. The currents impact helps shape the rocky shoreline into the ecological community of different species of shore life into a pattern of different zones (zonation).
