Grateloupia turuturu an Invasive Seaweed in Eastern Long Island Sound investigation into slowing its spread
Introduction
Long Island Sound is a complex and unique environment because of its glacial history and properties as an estuary. It has the capability to be a powerhouse for primary production, unfortunately, the sound has fallen victim to invasive species. Grateloupia turuturu is one such species, tormenting the natural flow of life in the coastal waters of Rhode Island, Connecticut, and New York (Balcom and Yarish, 2006). This red alga grows year round and is well suited for warm waters (Mathieson, A., et al, 2008). Their ability to grow year round gives the seaweed an advantage amongst other competitors that tend to sprout in warmer

turuturu in a controlled lab environment evaluating methods to combat continued growth of this Asian Pacific species. This species is difficult eradicate because it is well suited for the non-turbulent and low salinity waters in LIS (Heinonen 2006). The purpose behind our design is to test the replant ability of the seaweed in a lab environment and testing the viability of the plant in very cold waters. G. turuturu is a high risk invader in LIS that has the potential to devastate local ecosystems (Heinonen 2006).
We hypothesize that if this seaweed is capable of replant then it can survive moderate turbulence and steady boating traffic, which is common in the sound. If also G. turuturu can survive the low temperatures of LIS in winter months when recreated in a lab environment, then other methods need to be explored, because extraction is impossible with the growth and spore abilities of this weed. G. turuturu can generate up to 300 blades in one month (Heinonen

We want to test the lower limits of this spectrum, holding our subjects at a range of 2°C, 4°C, and 6°C conditions to see how well the plant survives and grows.
Our prediction is that G. turuturu will be viable even at extreme temperatures like 2c, but will not maintain the healthy growth and color of the same plant in warmer water. For this experiment we will need to have been successful in transplanting G. turuturu to a lab setting and will need access to a cooler with day/night light exposure simulation capabilites which can be found at Avery Point facilities.
Broader Impact:
This experiment can provide the information necessary to isolate the conditions necessary to combat further growth of Grateloupia turuturu in LIS. The idea behind our experiment is to understand the properties of the rhodophyta species to prevent having to resort to round-up style chemicals to prevent

    The GBR’s coral rarely grow lower than 40 meters below sea level since sunlight passes through shallow and clear waters. It has no real soil, being a marine coral ecosystem, but loose carbonate mud covers 135,000 square miles of land. Its biotic factors are animals & plants. It is highly diverse, with 1,500 fish species, hundreds of types of corals, 500 algae species, and many sharks, rays, marine mammals, crustaceans, and echinoderms. Animals like the dugong, butterfly fish, jellyfish, green sea turtle, tiger shark, blue-ringed octopus, krill, cuttlefish, and Crown of Thorns starfish, although of different species, sizes, and niches, all adapt for one of two common goals: to eat or to keep from being eaten.…

    Biology Essay Ecology is a biological subdivision that focuses on the relationships between organisms and their physical surroundings [1]. An ecosystem is a particular branch of ecology, comprised of biotic communities and the abiotic factors by which they interact with [2]. An example of an ecosystem with different biotic and abiotic factors is a mangrove forest. Mangrove forests are extremely fertile and make up some of the most densely-populated and widespread coastal ecosystems in the world [3]. The majority of mangrove ecosystems are accompanied by regions of coastal land called mudflats.…

    Introduction: Australia’s Great Barrier Reef (GBR), one of the world’s most precious marine ecosystems, has been deteriorating due to poor water quality (Kroon et al., 2016). One of the main reasons for this substantial decline in water quality over recent decades is agricultural runoff of nitrogen, pesticides/ herbicides and sediment (Figure 1). In fact, the water quality is most affected in the inshore areas in the southern and central regions near the most intensive agriculture. The impacts are biophysical in their effects on the marine animal and plants of the Reef. For example, coral cover declined about 50 percent from 1985-2013 (Brodie et al., 2013, p.2).…

    When algal blooms are prevalent in bodies of water, specifically bays, they can cause the nitrogen levels in the water to increase. When the nitrogen levels in the water are increased, this can lead to a number of detrimental health effects when consumed. In order to determine whether or not the salinity of the water in Barnegat Bay had an effect on the rate of the nitrogen levels increasing during an algal bloom, ten sample of water were collected and tested by adding the microalgae Nannochloropsis and recording the nitrate and nitrite levels every week. The sample of water varied in salinity, and two samples did not contain the algae to act as a control. The samples were exposed to a temperature of 22°C and were tested over the course of…

    My endangered species is called the Bog Turtle. The Latin name for the bog turtle is the Glyptemys Muhlenberg. The bog turtle is the smallest turtle species in North America, growing to only 3 to 4 inches and weighing less than 4 ounces. They are mostly found in the northeast U.S region. My species is going to go extinct because bog turtles are not needed much in the food chain and the animals that do consume it, the turtle isn’t their primary source of food intake, there aren’t many left…

    If Phragmites find their way into an agricultural crop, it will cause economic loss (Ontario Ministry of Natural Resources, 2011). Property values will drop in areas where monocultures are found (Ontario Ministry of Natural Resources, 2011). Phragmites have already impacted the recreational value of the beaches in the Georgian Bay area (Crowe et al., 2011). Charismatic native species, such as the 6 freshwater turtle species in Long Point, will see drastic population declines which impacts the communities surrounding Long Point personally (Bolton & Brooks, 2010). This is why the Invasive Alien Species Strategy for Canada was approved and why Acts, such as the Plant Protection Act, prevent movement of invasive pests between provinces (Government of Canada, 1990).…

    We have been able to observe marine organism in the clade Littorinimorpha in the three tides zones high, mid, and low each have their own ecological niche for marine organisms. But there is some marine life that are able to live in patchiness within zones and thrive in more than one. The high intertidal zones are home to marine life that are more tolerant to air, like barnacles (Ricketts et al. 1968). The mid zone includes higher low water and lower low water, which can be indicated by limpets (Ricketts et al. 1968). Last the low zone includes those that are normally uncovered during minus tides (Ricketts et al. 1968).…

    Kelp, our one and only source of nutrition, is nearly gone. With the remaining resources we have, we’d only last a few more weeks. Along with our weak source of kelp, it has contracted an extreme disease that seems to be spreading rapidly. There are scientists that are working on a solution for the contracted virus, however, there seems to be no sign of a solution, nor no signs of obtaining an idea for the solution either. On top of this, it seems our water source has been rapidly decreasing, as the scientist have been using it as a main ingredient in their solution to the kelp epidemic.…

    The value of the invasive Water hyacinth classifies as both detrimental and beneficial. The authors of The Jepson Manual, Vascular Plants of California describe the invasive plant as “Perhaps the world’s most troublesome aquatic weed.” The despised notions come from the fact that the aquatic weed increases its capacity to spread in water; peculiarly when the plant distances from its natural enemies in South America. The Water hyacinth growth appears as an island in freshwater bodies, or as a mat floating freely on the top of riverbanks. The Water hyacinth grows quicker in polluted ponds and lakes along with other nutrient-rich waters, and in the time span of 4-7 days the mats these plants form can nearly double.…

    n the Carboniferous Period, specifically in the Pennsylvanian subsystem, between 323 and 299 million years ago, a substantial change occurred around the planet: the climate increased strongly so that oceans growed up more than two hundred meters above the level existed immediately before this period. The increase of the level of water allowed the developing and diversification of the first vascular plants, i.e., plants that alternate generations between the sexual gamete production (gametophyte) and the sexual stage (sporophyte). Through this period would have arisen three types of flora beyond red, green, brown algae, and ditoms: these are ferns, lycopods and sphenopsids (flora 1), the gymnospears, or vascular plants able for producing naked…

    According to our results, we accept our alternative hypothesis, that the specific respiration rate of Triticum aestivum germinating seedlings that were incubated at 37°C was lower than that of the germinating seedlings kept at 25°C. Therefore, we reject our null hypothesis. Thus, we concluded that temperature has an effect on germinating wheat seedlings, in that the higher the temperature the lower the rate of respiration will be. Likewise, the colder the temperature the higher the rate of respiration will be.…

    All fronds are potentially fertile; there is no morphological distinction between infertile and fertile fronds. Spores are minute. They are borne in sporangia which congregate in a continuous line along the undersurface margins of the pinnae (Parsons, 1961; Krochmal, 1973). There is an indefinite or rudimentary inner indusium which is further covered by the false indusium. The false indusium is the leaf margin rolled back over the marginal sori.…
