Determining the Density of Seagrass at Different Substrates
INTRODUCTION
Background of the Study Seagrasses are the marine flowering plants. They are the only angiosperms that successfully grow in tidal and subtidal marine environment. Seagrasses belong to the families, Hydrocharitaceae and Potamogetonaceae and they are in no way related to the terrestrial grasses of Poaceae. There are 13 genera and 58 species available all over the world. Of these, six genera (Amphibolis, Heterozostera, Phyllospadix, Posidonia, Pseudalthenia and Zostera) are mostly restricted to temperate seas and the remaining seven genera (Cymodocea, Enhalus, Halodule, Halophila, Syringodium, Thalassia and Thalassodendron) are distributed in tropical seas (L. Kannan, T. Thangaradjou). They grow and reproduce sexually being continuously submerged under water. They do not require contact with air, and the reproductive cycle with flowering and pollination is completed under water. Seagrasses have a number of adaptations to the submerged life form (Borum et al, 2004). Thalassia hemprichii is common on mud-coral-sand or coarse coral-sand substrates, in sheltered habitats in the Philippines. The plant has been observed growing from the base and through fingers of corals at 6 m deep. T. hemprichii may be found mixed with Syringodium isoetifolium, Cymodocea serrulata, C. rotundata, Enhalus acoroides, Halophila ovalis, and Halodule uninervis (Calumpong et al, 1983).

Locale of the Study This was conducted at Brgy. San Pedro, Panabo City.

Delimination of the Study This study was concerned in determining the density of seagrass specifically Thalassia hemprichii at different substrate at Brgy. San Pedro, Panabo City.

Objectives In this study, the objective is to determine the present status of Thalassia hemprichii in coastal area at Brgy. San Pedro, Panabo City. This study specifically aims to: 1. Determine the population density of Thalassia hemprichii in the area; 2. Compare the density of Thalassia hemprichii among the three(3)

    Mangroves are essential to marine, freshwater and terrestrial biodiversity, because they stabilise coastlines against erosion, collect sediments and provide a nursery for coastal fish. However, mangroves are at threat; over 50% of the world’s original mangrove forests have been lost. This has been due to many factors such as, shrimp farming, climate change, over-harvesting etc. As a result, there are many players who are trying to halt the loss of mangroves to protect and restore them.…

    The invading Asian shore crab (Hemigrapsus sanguineus), has been a growing cause for concern for over a decade in Southeastern Massachusetts. It is suspected that the species was first introduced in the U.S. as adults or larvae present in ballast water discharged from incoming global trade ships. The first specimen in the U.S. was recorded in Townsend Inlet, Cape May County, NJ in 1988. The first appearance in Massachusetts was near Woods Hole on Cape Cod in 1992. By 1994, the Asian shore crab was identified in my hometown of Fairhaven, MA. As a precautionary measure, the ballast water of incoming international trade ships are monitored to prevent and eradicate new introductions of the species. Researchers are also conducting experiments to…

    In 1982, there were 178 different species of vascular plants identified from the Belize coast, 32 of which are non-native. Mangroves are dominant among many of the southern cayes, while shrubs and coconut trees also thrive in the subtropical temperatures. The barrier reef holds around 247 species of marine plant life. Most dominant are the seagrass beds, shoalgrass, and manatee grass which host living organisms and trap sediments and nutrients to the ocean floor.…

    Submerged aquatic vegetation (SAV) are plants that have adapted to live within aquatic environments (DNR 2011). SAV are able to float in the water and move with the currents because they contain specialized cells called aerenchyma that provide buoyancy and they lack the more rigid structures of most terrestrial plants (DNR 2011). Many different species of SAV are found throughout estuarine waters worldwide and there are seventeen species of SAV that are commonly found throughout the Chesapeake Bay and its tributaries (VIMS 2010). SAV is found throughout the Chesapeake Bay.…

    2009), thirteen species were studied of Spartina ranging high to low marsh and freshwater habitats. The scientists studying Spartina grasses used light and electron microscopes to measure and record the number of stomata on the adaxial side of the leaf. Thirteen species were collected and examined: Spartina alterniflora, Spartina anglica, Spartina argentineses, Spartina bakeri, Spartina densiflora, Spartina patens, Spartina spartinae, Spartina cynosuriodes, Spartina pectinata, and Spartina gracilis. The species were compared against herbarium specimens and Flora from the North American Keys; but the populations used in the study were grown under greenhouse conditions in Fort Hays State University and Washington State University. The scientists studying Spartina grasses used light and electron microscopes to measure and record the number of stomata on the abaxial and adaxial side of the leaf. Results showed that in freshwater species, there were more stomata on both sides; conversely, in saltwater species, there were more stomata on the adaxial side. Saltwater species were able to better adapt to their climate and water loss due to the number of stomata present (Maricle et al.…

    Dinoflagellates are common and abundant to the marine and estuarine system, it were characterized by the 2 flagella that are located on the girdle and sulcus. The girdle grooves divides the body into 2 parts, in which its orientation, size and shape can be used to indentify them in morphological taxonomy. Toxic dinoflagellates are known to cause diarhetic shellfish poisoning (DSP), paralytic shellfish poisoning (PSP), neurotoxic shellfish poisoning (NSP), and Ciguateria shellfish poisoning (CSP), hepatotoxicity, and toxicity to the marine fauna. Thus their bloom is harmfull to the ecosystem and to human health. Dinoflagellates can bloom by the natural means, but this occurance can be advance by the anthropogenic nutrient from the agriculture, aquaculture and animal farming industry, the change in the N: P ratio also encourages the dinoflagellates to overcompete the other algal species. Dinoflagellates distribution is limited to the biogeographical range of each species, there are 3 common distribution of dinoflagellates with the example of tropical and subtropical distribution of Pyrodinium bahamese, mid to high latitude distribution of Alexandrum catenella, that have a diverse distribution ranging from temperate to tropical water of Prorocentrum lima.…
