The Study of Salinity Levels on Abundance of Species and Biodiversity 7

Thestudy investigates two major places which are White Sand Island (Ws)and Trikora Bintan (Tb). In both of these places there were manyuncertainties that lead to a thought why mangrove trees havedistinction on the basis of land and environmental conditions. Aresearch paper on Bruguieraand Kandelia species on mangroves concluded that inbreeding andgenetically exchange is one of the causes for uncertainties inmangroves (Islam,Lian, Kameyama, &amp Hogestu, 2012).Their condition which is based on the land, wave energy andenvironment these condition allow difficult species to grow in auncertain manner where one tree species could have healthy breedingand increasing, and same species having different land can have aless healthier outcome. To fulfill the objectives, author selectedthese two lands on the basis of plots and how these were growing. Theresearch selected species of mangroves to find the abundance on thesetree and what are the diverse factors that are in those species withrespect to land. The three species were Rhizoporastylosa,Bruguieriagymnohirza and Soneratia Alba these species were selectedon different plots. White Sand Island had six plots selected thatwere most suited for the research and on Trikora Bintan, there werefour plots with two mangrove species Rhizoporastylosa and SoneratiaAlba.

Adiversity index is the measurement of species community diversity. Itprovides community information about the species richness includingrelative abundance on species of different types(Beals, Gross, &amp Harrell, 2000).Keeping the diversity in consideration, theresearch concluded that White Sand Island had higher Shannondiversity as compare to Trikora Bintan. After applying the Shannondiversity and evenness, the mangroves trees on white sand plot hadvaried diversity on plot four to six leaving zero diverse andevenness factor on plot on one to three. On one to three plots thatwere selected at Trikora Bintan, they had zero diverse and evennessfactor. These factors lead the research to an outcome that White SandIsland had more diversity than Trikora Bintan. It was also notedthat both the land were segregated with less similarities.

Salinitywhich is the salt factor was among the consideration. By keeping thesalinity of the land in research, the outcome in this categorysuggested that there were various dissimilarity in different plots,but on similar land the salinity level was similar having mostsalinity at plot six on White Sand Island, and on Trikora Bintan, themost level of salinity was at plot four that made it easier todetermine the abundance of tree based on the salinity level.

Thereare different factors that affect the abundance of trees on differenttype of land. These factors vary with respect to the abundance,making richness of tree at one place and leaving the other land asdried. These factors are constantly researched by the scientificcommunity to understand the mangrove tree and their growing habits.Checking the outcome that indicated that White Sand Island have richRhizoporastylosaspecieswith rich diversity level as compared to the Trikora Bintan which hadlesser Rhizoporastylosa species but increased in Soneratia Albaspecies. This outcome suggests that salinity level plays an importantrole in the growth of trees of different species, and diversityfactor of those trees also to be considered for understanding thenature of these anomalies that happen on different sites.

Basedon the salinity level, the Rhizophorastylosa prefer both low and highsalinity level as compared to other species of mangrove,Bruguieriagynmnohirza which is more vulnerable compare to otherspecies preferred atmosphere where there is less exposure of wave andcurrent, and the Sonneratia alba prefer an atmosphere having sandy orrocky shores near coastlines. These Outcomes explain theindividuality of trees and their behavior on their supportedatmosphere.

Thegraph explains the salinity level of the White Sand Island which is30.31 with high tides, and at Trikora Bintan there were 29.25 withlower tides.

Theaverage P value for both the lands were 0.982 having individual levelof 0.999 to the White Sand Island and 0.836 on the TrikoraBintan.These specimens indicate that how these species are going ondifferent circumstance on different coastlines. One species havingresponsive towards salinity and tolerates it and on the other handsimilar species having needed softer environment with rockysurrounds. These analysis leads to an understanding that mangrovesfollow to increase their breading and survival rate. The data alsopoints towards response of those trees with respect to theirenvironment condition. Keeping the point in mind that one mangrovespecies is abundance on one land and on the other it’s not showshow these changes are related to their breeding mechanism, bydefining the relation between salinity, diversity and abundance.Therefore tree growth depends on the environmental conditions whichmake different species to spread their breeding this factor can alsobe reflected on different plots on same land.

Theresearch also evaluate that there is much to be done in the threeaspects of mangrove trees. The author can improve the level ofsampling to increase more percentage value by including more plotsand measuring their salinity level and at the same time notifying thePh level which plays important part in defining the tree growth oncertain land. These improvements can also be done in notification ofmagnitude of wave exposure of the mangrove species and how theseexposures are affecting different species on different locations.Wood debris measurement also plays significant role and improving theresearch by adding these measurements will help notify the behaviorof these trees so that further research can be carried out on thisparticular topic. The last research aspect that author want to add isthe girth size of the trees, by doing that more scientific data canbe collected to understand the nature of these trees and theirbreeding mechanism which makes them distinct among each other.

Thereare many other factors that include the environmental health andwater condition that defines the certain behavior of trees ofdifferent kinds and species. After studying the nature of these treesand their abundance on the basis of different anomalies, we can helpsave different species on places where the need of saving these treesis necessary. These factors that affect trees will also help inkeeping the species at bay and under consideration. In past there aremany examples available when many species are abundant or vanishedbecause of the lack of data available on them, and by understandthese factors saving trees and controlling their population ondifferent locations can be done. A research said that mangroves arethe most productive and diverse wetland on earth (Singh,Shrivastava, Gupta, Thakur, &amp Mukherjee, 2013),and understanding the nature of these trees will help save them infuture.
