The Effect Of Algae Growth On Mud Snails

Ocean acidification is an emerging global problem. In some parts of the Pacific, the ocean’s PH levels are so low, that its dissolving sea snails’ shells. Try saying that three times quickly. According to PMEL Carbon Program, the shells will go from completely normal, to nothing in just about 45 days at the moment. As the Oceans acidity increases, the

The data suggests Habitat A (close to shore) had a greater species richness in comparison to Habitat B (one meter from shore), whereby the mean scores are 5 ± 1.67 and 4.5 ±1.52 respectively (see Table 1.0). Figure 1.0 compares the distribution of data for both datasets and graphically illustrates the five number summary. Habitat A’s graph has a greater range than Habitat B, whereby 50% of the data from Habitat A obtained a species richness value from 5 to 8. Conversely, 50% of Habitat B’s dataset lies within 4 and 6.

Present all relevant data in a data table below. Include an observations section for any observations you made during the lab. Make sure you note the data needs to be converted before graphing.

You may also draw it neatly by hand and scan your drawing. If you choose this option, you must insert the scanned jpg image here.

In this research paper I will talk about how a large decrease in the algae population in the Chesapeake Bay will cause problems for not just fish and other species but the people who fish and make a living off of it. A large decrease in algae population will have a domino effect on the food chain. Having a major decrease in algae will hurt how others species live and protect themselves.

Silvershell Beach is the home to many different aquatic species and other forms of wildlife. Last lab block the class and I went into the ocean at Silvershell beach and took seven different seine net samples. With each sample we took, we noticed a variety of different organisms. As we moved around different areas of the ocean, we would come out with changing species and number of species that we did not find in other areas of the water. Species we found included sea robin, hermit crabs, moon jellies, minnows, shrimp, eels, and more. Sample one and two were taken from around the same area in the water and there was a reappearance of three of the species. In sample one we found hermit crabs, minnows, moon jellies, and a sea robin. In sample two

With a decrease in algae population, the grasses of the bay will be fed on by zooplankton, oysters, and fish. Without the algae, there would be a huge decrease in Bay grasses. This happens because Zooplankton, oysters, and fish will no longer eat the algae, they would resort to the Bay grasses. The effects then go onto the plants and animals living here. (Science Daily)

The removal method of Ringed Crayfish data collection was over a sample site area of 50m2 at Pearson Creek, a stream, containing a density of 5.18 crayfish/m2. The sample site was collected in 5m in width by 10m in height with wet, rocky, and grassy conditions. The data collection incorporated five different samples of the number of crayfish removed from the stream each time (Figure 1). Sample one caught 53 Ringed Crayfish with 0 crayfish caught prior. Sample two caught 37 Ringed Crayfish with 53 crayfish caught prior. Sample three caught 42 Ringed Crayfish with 90 crayfish caught prior. Sample four caught 26 Ringed Crayfish with 132 crayfish caught prior. Sample five caught 18 Ringed Crayfish with 158 crayfish caught prior. What was caught in the previous sample was added into the total amount of crayfish caught prior. A negative linear relationship is displayed by data collected in Figure

Different aquatic invertebrates live in different micro habitats (smaller habitats) at Lake Tonetta. Some live on the surface of the water. Others live in the bottom of the lake, or deep within the sediments at the bottom of the lake. The water pH is important because they only can live in a specific pH 6.5-7.5.When we visit the lake our group checked the biodiversity (The variety of plants and animal species in an environment)of Lake Tonetta by counting the aquatic invertebrates in a sample obtained using dip nets and bottom scrapers. During our trip, we found beetles, snails, worms ,

Daphnia Magna will be used to measure how quickly dead zones are forming by eutrophication. We will use three different endpoints to measure the Daphnia Magna: Heartbeat, Mobility, and Mortality. We will have three fertilizers mixed with pond water in three separate test tubes per fertilizer with Daphnia Magna and one without ferilizer as the control. There will be three different sets each set will contain four test tubes: Three test tubes each with different fertilizers and one without as the control. We will then measure the three endpoints of the Daphnia Magna after thirty minutes which will be repeated for each set thus the whole experiment will last 90 minutes. The equipment needed for the experiment is the following:

Freshwater invertebrates make up a vast amount of Alabama’s Biodiversity. Biodiversity is the variability among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems. Mollusca which are also known as snails are one the most commonly encountered in Alabama. They spend the majority of their life in an aquatic ecosystem. As a matter of fact, Their are 180 different species of Mollusca in Alabama.There are unique species associated with every type of aquatic habitat from the Canadian Arctic to the Everglades of Florida. Mollusca are highly valued because they are either a food source or biological indicators for a healthy habitat.They prove immensely beneficial both economically and medicinally. Alabama

Along the coasts of rocky beaches, an intricate ecological community inhabits the ‘rocky intertidal’ areas. The variety of rocks is home to an array of slimy, squishy, and colorful organisms. This intertidal community is comprised of nine species: three different algae, three stationary filter-feeders, and three mobile consumers. The three algae, Nori Seaweed, Black Pine, and Coral Weed, are the community’s producers and inhabit the bottom of the food chain. The next three species are stationary consumers. They are Mussel, Goose Neck Barnacle, and Acorn Barnacle. Because of their consumer status, they are more competitively dominant than algae. The last three components are the mobile consumers: Whelk, Chiton, and Starfish. They

The ecosystem with which the simulation is being done is an aquatic ecosystem. This specific ecosystem is home to producers such as: black pine, coral weed, and nori seaweed. Stationary consumers like acorn barnacles, gooseneck barnacles, and mussels are also present. Mobile consumers such as chitin, starfish, and whelk. The invasive mobile consumer is the green crab. Animals such as starfish compete with others like green crabs for mussels. Starfish and whelk prey on and also compete for the gooseneck barnacle. Whelk and green crab also compete for the acorn barnacles. The competition between starfish and green crab over mussels is what led me to my hypothesis as the mussel is one of the largest secondary consumers in terms

Two cobble samples from three sets of riffles and pools across each study reach were used to determine algal biomass. Each cobble was scraped and the
