- Can live in water 100 saltier than other plants’ tolerance.
Characteristics of Mangroves
- Cope with salt: Saltwater can kill plants, so mangroves must extract freshwater from the seawater that surrounds them. Many mangrove species survive by filtering out as much as 90 percent of the salt found in seawater as it enters their roots. Some species excrete salt through glands in their leaves. These leaves, which are covered with dried salt crystals, taste salty if you lick them. A third strategy used by some mangrove

- Some mangroves will reproduce through extending its root to for daughter plant from the parent plant.
Why are mangroves important?
Importance of Mangroves in Coastal System
- Always appear with seagrass beds and coral reefs.
- Trap sediments that would otherwise flow into the sea.
- Seagrass beds provide a further barrier to silts and muds that could smother the coral reefs.
- In return, coral reefs protect mangroves and seagrass beds from strong ocean waves.
- Whole ecosystem breaks down without the existence of Mangroves.
Nursery Grounds and Home for Many Species
- Provides ideal breeding grounds for most of the world’s fish, shrimps, crabs and shellfish.
- Many fish species, such as barracuda, tarpon, and snook, find shelter among the mangrove roots as juveniles, head out to forage in the seagrass beds as they grow, and move into the open ocean as adults.
- An estimated 75 percent of commercially caught fish spend some time in the mangroves or depend on food webs that can be traced back to these coastal forest.
- Provides habitats for thousands of
Hastings Point Lab Report
1610 Words | 7 PagesIntroduction For two days, on the 14th and 15th of April, a field excursion to Hastings Point, New South Wales was conducted. At Hastings Point, topography, abiotic factors and organism distribution were measured and recorded, with the aim of drawing links between the abiotic factors of two ecosystems (rocky shore and sand dunes), the organisms which live in them, and the adaptations they have developed to cope with these conditions. Within these two ecosystems, multiple zones were identified and recorded, and this report also aims to identify the factors and organisms associated with each zone. Lastly, using data and observations from the past, predictions for the future of the rock pool ecosystem were made.

Florida Keys Ecosystems
1315 Words | 6 PagesThese banks contain coral rubble, seagrass and macroalgae with other invertebrate taxa, which play a key part in the ecosystem. The bank systems contain essential fish habitats, which provide sheltering and foraging grounds. Past studies have indicated these fish assemblages showed a high diversity and biomass of coral reefs. Most of the biomass in the Florida Keys ecosystem is made up of species that stay in channels for most of the day. These signs show that the bank systems are important for the FKNMS for providing a structural support and high productivity for the biodiversity.

Artificial Reefs: A Rhetorical Analysis
1851 Words | 8 PagesOceans are peaceful, majestic, and filled with amazing and vibrant color. A lot of the prostown beauty in oceans can be credited to coral reefs. Lately though, natural coral reefs have been dying for various reasons, and some people believe that artificial reefs can help not only the natural reefs, but other surrounding ecosystems in their environment. Various articles use rhetorical techniques in hopes of enhancing their articles about whether or not artificial reefs are helping or harming the oceans. The first article, “Concern Lingers on Success of Artificial Reefs”, was written by Charles Q. Choi, and for Live Science, looks at both the pro and con side of artificial reefs.
Cray Fish Lab Report
1117 Words | 5 PagesCrayfish Response In this experiment the researchers were investigating the limited range of the crayfish species Orconectes saxatilis in the upper part of the Kiamichi River. The dispersal of the crayfish species O. saxatilis and two sympatric crayfish species throughout the upper part of the Kiamichi River were examined. The type of habitat that the crayfish favor for use was also examined along with their historical characteristics. Crayfish species with small habitats are in major need of conservation but little information is known about species-specific habitats.
Great Barrier Reef Negative Impacts
1251 Words | 6 PagesNegative Impacts Environmental Environmental impacts for example, Climate change, especially the rising ocean temperatures and Ocean Acidification is as of now influencing the Great Barrier Reefs Ecosystem. Coral bleaching coming about because of expanding ocean temperature and lower rates of calcification in skeleton-building life forms, for example, corals, because of sea acidification, are the impacts of most concern and are as of now obvious. Agricultural sources are adding to the waterfront and inshore territories of the Great Barrier Reef by expanded Nutrients, Sediments and different Pollutants in the catchment runoff.

A Marine biologist is a scientist who studies marine organisms and studies the bodies, behavior, and the history of marine organisms. They also study how marine organisms interact with each other and their environment. I have chosen to research about Marine biology because I would like to learn about sea life, the ocean, and its surrounding environment. To start off, a Marine biologist might study coral, crabs, fish, microscopic marine organisms, sea stars, seaweed, squid, or whales.
Commercial Fishing Impacts
1235 Words | 5 PagesCertain species have a huge impact to an ecosystem, but even the smallest fish could have the biggest impact. Overfishing occurs when more fish are caught than the population can replace through natural reproduction (overfishing). The results not only affect the balance of life in the oceans, but could also affect the coastal areas that depend on fish for their way of life. For centuries, our seas and oceans seem to be considered a limitless food supply. But that is not the case, increasing fishing efforts over the last fifty years as well as unjustifiable fishing practices are pushing many fish stocks to the point of extinction.
Consequences Of Overfishing
800 Words | 4 PagesTherefore, the impact of overfishing and illegal collecting of coral may destroyed the social and economic well-being of the coastal communities who depend on fish for their way of life. Beside, it is also direct overexploitation of fish, intertebrates, and algae for food and the aquarium trade, removal of a species or group of species impacting multiple trophic levels, bycatch and mortality of nontarget species, and change from coral to algal dominance due to reduction in herbivores (Reef Resilience Organisation,
