Littorina spp, or more commonly know as the periwinkle snail, is a small robust species that inhabits the intertidal zone and are commonly used in the preparation of many dishes in countries such as England and China. Littorina spp commonly ranges from sizes of 0.5-1.5 inches long with dark and even banded shells which help it to withstand strong waves. There is no definite life span of the periwinkle snail however, the amount of food and environmental factors can play a role in how long they can live for. Unlike most snails during breeding, Littorina spp often can spend more time out of the water as the embroys are contained within a brood sac and are unaffected by the external changes in the environment. Even thought periwinkle snails are a robust species a change in an …show more content…

In this experiment the research objective is to determine how far Littorina spp will travel within a given time frame in two different water salinities of 10 ppt and 30 ppt. From the range of tolerances and information collected from other similar experiments the prediction for this experiment is that in the 30 ppt salinity water the periwinkle snail will travel further and in the 10 ppt salinity water the periwinkle …show more content…

As stated above changes in salinity can affect the mobility and activity of marine organisms. The tolerance range of Littorina spp ranges from 10ppt to 40 ppt salinity water. Hylleberg

Isopods typically eat, fruits,weeds, fungi, and animals, both dead and alive. However, when there is a drought the crustacean becomes a scavenger, willing to eat whatever it encounters. Opposingly to these conditions is their behavior when their environment is entrenched by too much water, when this happens Isopods endure a great deal of stress. The perfect medium for them is a damp and cool environment, such as burrows in logs and underneath soil (Brown, 1999). For this experiment we used syrup and water as our independent variables.

This adaptation is to retain moisture using a special structure – the operculum – which can be sealed when the snail is not eating to retain moisture within the shell. This is used especially between the high tides, as water only reaches this high zone at these times. Another factor associated with the supralittoral zone is harsh wind conditions, which was observed at Hastings Point where the temperature indicated a 12% increase in average temperature between the littoral and supralittoral zones. The black nerites adapted behaviourally to survive these conditions. To do this,

Once acclimated, the isopods walked around the arena for five minutes and go to the sponges that they preferred. The experiments should be repeated 3 times with the same design layout for accurate results. 20 isopods were released in the center of the arena. After five minutes, the number of isopods behind every sponge was

Coast Miwok first inhabited the island about 2,000 years ago. In 1863 during the Civil War, the U.S. Army built a base on Angel Island. They established Camp Reynolds for soldiers to live in. The army built batteries, which are gunning sites, around the island to protect San Fransisco. In the 1950’s, the army also built a project nike missile site, which is an anti-aircraft weapon (named after nike

The experiment consisted of two sub-experiments that when synthesized together, successfully answered our main question. The first of the two sub-experiments focused on collecting data for the creation of a life table in which Daphnia magna were not in the presence of a predator such as Lepomis macrochirus, known in laymen’s terms as bluegill fish. The second of the two sub-experiments focused on collecting data for the creation of a life table as well, but this time the daphnia were subjected to an environment where bluegill fish were present. The collection of the data for the creation of the first lifetable without predation consisted of fourteen replicates or daphnia starting at age 3 and ending at varying ages depending on the mortality of each replicate group.

If the wind is blowing either East or West the plankton are more likely to be distributed because the lake runs North to South. The air temperature on September 17th, 2015 was 27 degrees Celsius with a cloudless sky and winds blowing from the West at 10 mph. To test the temperature profile of the water column we used the water sampler to collect water starting from the surface and taking it a half-meter down each time. After performing this at multiple depths you record the temperature after 2 minutes from each sample and any relative information about that water. We counted for a hundred protists at each depth (2, 3, and 4 m), 5 rotifer cells at each depth (2, 3, and 4 m), and 5 arthropod cells at each depth (2, 3, and 4 m).

Daphnia magna is a transparent water flea species found in rocky pools along the Atlantic Ocean. The Daphnia’s body is encased in a clear structure called carapace (Elenbaas, 2013). The exoskeleton, carapace, provides protection for the Daphnia magna, “The portion of the hard exoskeleton, or shell, that covers all or part of the body of many crustaceans…” (“Definition, n.d.). The heart can be easily seen under a light microscope due to the transparency of the skin (Handy, 2012).

2. Methods and Materials 2.1 Study Area Apalachicola Bay is a wide estuarine system located in the Florida panhandle and covers an area about 539 km2 (Figure 1). The bay is relatively shallow with an average depth of 3.0 m. It is one of the most productive natural systems in North America, and highly recognized by the state, federal and international organizations for its pristine water quality and unaffected estuarine habitats (ANERR, 2008). Apalachicola Bay was formed by the deltaic processes of the Apalachicola River, which is a relatively unpolluted alluvial system.

Salinity Changes With Sheepshead Minnows Sheepshead minnows are one of the few fish that can survive in a big change in salinity and temperature. I would like to observe how long they can survive in a certain amount of salinity with small changes in salinity over time. I will slowly over five day period, take away salt from the sheepshead minnows tank. I will have twenty sheepshead minnows in all, ten in the tank having the salt removed and another ten in a tank with the same salinity as the water I found them in. This is important because we can learn how some animals adapt over time to live in different environments.

THE GREAT LAKES The great lakes are comprised of 5 different fresh water lakes, Superior, Huron, Michigan, Ontario, and Erie. The lakes are situated along the US-Canadian border, touching Ontario in Canada and Michigan, Minnesota, Wisconsin, Illinois, Ohio Pennsylvania, Indiana and New York in the United States. Roughly 34 million people in Canada and the United States live in the great lakes basin, and also 35 000 plants and animals, over 170 of those being fish, inhabit the great lakes (Zimmermann). This significantly large water body holds an estimate of 6 quadrillion gallons of water.

These turtles are often found in large groups basking in the sun on a partially submerged log or rock. Basking is needed for survival for these turtles because they are cold-blooded and basking allows them to regulate body temperature. Also while basking the sun helps get rid of parasitic leeches. During the night these turtle rest at the bottom of a pond usually because they are diurnal meaning: active during day. Painted turtle’s also

Great choices, I read a couple of previously discussion and I believe most of us have different answers, but they all relate. Therefore, your choices of overkill, habitat destructions, introduction of animals and disease it’s a little different. Mostly, I was curious with your choice of introduction of animal and how that came to be one of your choices. In general, I agree after reading your example of the tree snails of Tahiti and Moorea on how the government introduced the giant African snail as a food animal.

Same as usual, since the conditions seem to not differ as much. The biome is just, worse, the snails are dead. They seem to be giving off their body parts like corn flakes in a cereal bowl, mixed with milk. The shells are flipped, with one shell floating, but dispersing off its flaky body parts. The aquatic biome is still crashed, just like last time.

Sea Sponges are animals that live in the ocean floor. They are the simplest animals and can produce asexually and sexually. They are favored over synthetic sponges because of their softness and their ability to stop mold, mildew, and bacteria. Sponges are harvested by divers who cut sponges off of their bases with hooks. AFter the divers cut the animal off of its base the sponge will grow back on the same base in a few years.

If I was told to choose the best animal for a pet between the tortoise and the fish, I would choose the easiest to care for. The pet should be fun not a hassle. Since I only have a little time, my consideration is efficiency. Let's compare the turtles and the fish! Turtles are animals that can live in 2 realms, water and land.
