Spartina Alterniflora is a type of saltwater bay grass. Generally, it is found near water, but it is located on the east and west coast of the United States. The growth of this bay grass depends on the amount of salt, or salinity. Chemicals, such as pesticides can get onto the water, in which clouds it. This is a result of bay grass not getting enough sunlight. Not only that, but the extra nutrients causes algey to grow, blocking the sunlight even more. Bay grasses are not only for decorations in the water, but it is for our environment and the animals that live in the water. For instance, they are good for nurseries for various types of fish, like men haden, herring, shud, crokers, white perch, and weak fish. It also serves food for Barnacles, sponges, sea slugs, sea squirts, and more. For our environment, it improves water clarity by helping sediment settle to the bottom. Not only that, but it adds oxygen into the water, reduces shoreline erosion, buries bottom dwelling species, and absorbs exass nutrients. Sadly though, the abundance of these helpful bay grasses has been decreasing. In 2006, grasses in the upper bay fell 20%, for a total of 15,510 acres. In the middle bay, grasses dropped 23%, dropping to 30,659 acres. Finally, lower bay grasses dropped 25%, dropping from 78,263 acres, to 59,090 acre. By 2007, people had noticed a lot what was going on than before and started planning. The government decided to do a plan in which to increase the number of bay grass. By 2008, people were really listening and participating in this plan. In this plan, as I said, people are putting up bay grass restoration. The government is setting a goal of 185,000 acres of bay grass by 2010. This goal is going well, mentioning that it is 42% complete. Also, what the government wanted is to plant 1000 bay grasses by 2008. What WE can do to prevent bay grasses from dieing is to use less chemicals and more natural stuff. For instance, instead of using pesticides to kill bugs, plant other plants that help make insects’ back off. One idea is to plant marigold, a type of flower; to make bugs that like to eat vegetables back off.

...the species that can be found here are, Spartina alterniflora, Littoraria irrorata, Juncus roemerianus, Spartina patens, Salicornia virginica, Melampus bidentatus, etc. Many of these species hold a key role within this habit such as being a foundation species, or an indicator for the marsh health. Littoraria irrorata (periwinkle snails) amongst other gastropods and Molluscs have...

Littorina Irrorate

...Littorina irrorate (common name marsh periwinkle snails) perform a vertical migration on Spartina alterniflora (salt marsh cordgrass) during high tides. This could be a result in trying to avoid predators such as Callinectes sapidus (common name blue crab). Field studies have shown that the result of climbing up vegetation provides protection from predators. The comparison that is to be made, is the Littorina irrorates response to the presence of the Callinectes sapidus pheromones by vertical migration. The alternate hypothesis is that there will be a difference in how the Littorina irrorate react with the Callinectes sapidus pheromones, by the vertical movement the snails make to avoid the crabs compared to being in a non-pheromone seawater....

Review

...A Review of Literature Related to Oil Spill Dispersants 1997-2008 for Prince William Sound Regional Citizens’ Advisory Council (PWSRCAC) Anchorage, Alaska by Merv Fingas Spill Science Edmonton, Alberta PWSRCAC Contract Number - 955.08.03 Disclaimer: The opinions expressed in this PWSRCAC-commissioned report are not necessarily those of PWSRCAC September, 2008 ii Abstract This report is a review of the literature on oil spill dispersants published from 1997 to August, 2008. The report identifies and focusses on recent advances in dispersant effectiveness, toxicity, and biodegradation. Other topics such as application, use, behaviour and fate are also covered. The prime motivation for using dispersants is to reduce the impact of oil on shorelines, thus the application must be successful and effectiveness high. As some oil would come ashore, discussion remains on what effectiveness is required to significantly reduce the shoreline impact. A major issue is the actual effectiveness during spills so that these values can be used in estimates for the future. The second motivation for using dispersants is to reduce the impact on birds and mammals on the water surface. The benefits of using dispersants to reduce impacts on wildlife still remain unknown. The third motivation for using dispersants is to promote the biodegradation of oil in the water column. The effect of dispersants on biodegradation is still a matter of dispute. Some papers state that dispersants inhibit...
