Analyzing Interspecific Relations Between Species Found On The Rocky Shore

Limpets (Patella vulgate) live in algae rich environments on rocky shores. . It has been proposed that in more sheltered areas, limpet shells will grow to be flatter with a larger diameter, while in more exposed areas of coastline, they will grow a taller and narrower shell shape. To find out whether or not the shores of Aberdeen reflected this, samples were taken from two sites (Site A and Site B) along the Aberdeen coastline that varied in their exposure to wave action. The sites were chosen to provide two sample sites with a notable difference in their environment. In the more sheltered site A, limpets were not exposed to harsh waves, while at site B, there was significantly more wave action. Quadrats were used at both sites to provide an area of sampling for the limpets and they were placed around 5 meters from the waterline. The overall results from the study showed that there is a very strong relationship between diameter and height in Limpet shells and that there was an incredibly slight difference in the relationship between the two sites.

This study was conducted to deduce whether the height to width ratio of limpets altered across the three main zones on the shore: upper, middle and lower. It was carried out on Holbeck Beach, North Yorkshire, where limpets were measured in all three zones using random sampling. We found a significant difference in the height to width ratio between the upper and lower shore and upper and middle shore. This is due to many factors, including the threat of desiccation and strong waves.

This forty page, hardcover text includes short paragraphs on the left page and vibrant illustrations of coastal life by Roy Vickers on the right pages, except for a large picture covering pages 25 and 26. The story takes place in a Kitkatla, a small Tsimshian village community in northern B.C., near the town of Prince Rupert. The story brings to life a legend of the journey of

Although it supports a number of different organisms, Nudgee Beach lacks many of the fundamentals that make up a healthy and successful ecosystem. The first indicator of this is from the lack of birds present in the area. Although it has been noted for terrestrial bird species – such as kingfishers, pelicans, ibis, egrets, jabiru, stilts and heron – and wading bird species – such as golden plovers, curlews, tattlers and godwits – to have been spotted at Nudgee Beach and surrounding areas in the past; after a day’s worth of extensive observation and research, it was found that the birds observed were limited to magpie, ibis, great knot and eastern curlew species. To intensify this factor, at the time by which this lack of species was recorded, Nudgee Beach was expected to have started seeing tens of thousands of birds arrive for the migratory season [21]. This blatant lack of bird species diversity and quantity may have been due to the lack of small organisms within the ecosystem. The restricted number of small organisms at Nudgee Beach is detrimental to the entire ecosystem as these organisms make up the bottom levels of the food web and provide higher-level organisms with adequate amounts of food to consume. The smaller organisms expected to be observed – including; crustacean, shell, mollusc, lizard, frog, fish, worm, arachnid and insect species – was limited to the infrequent observation of crustacean, shell,

The aim of our excursion to Hastings Point, New South Wales was to study the biodiversity and ecology and to see how these organisms behave in their natural habitat and surroundings. There will also be information collected about a variety of different organisms as well as population counts and observe how they have adapted to the species surrounding environment. The excursion will also be an opportunity to gather information on

The sandy shores of beaches can be considered as a very harsh environment to live in (Ted Klenk, 1999). Survival in such a habitat requires an organism to withstand strong wave and current action, tidal rise and fall, unstable substrate, heavy predation and wide variations in salinity and temperature (The Otter Island Project). Any organism found in this type of harsh environment is specialized and highly adapted (The Otter Island Project).

Habitat: Commonly found in terrestrial. Forest light gaps, slips, margins, disturbed sites, open habitats, riverbeds, cliffs, inshore and offshore islands, fernland, herbfield,

The purpose of this research is to apply the knowledge learned about the ecology of the Hawaiian Coral Reef to a real-life situation. The coral reef stretches over 1,000 miles in the Pacific Ocean. In the Pacific Ocean, near the 124 islands of Hawaii, is the Hawaiian Coral Reef, which covers nearly 1,200 miles. Out of all the coral reefs in the world, the Hawaiian reef consists of 85% of all reefs. Coral Reefs are made of organisms, coral, and limestone skeletons. 25% of organisms are not existent anywhere else in the world. Abiotic factors are nonliving things, and abiotic factors of a coral reef are depth, light, wave motion, salinity, and temperature of the ocean. Biotic factors, living factors, is the whole coral reef,

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

Looking at the shape and size of the continental slope and continental shelf in the area, it seems that the animals observe the line by using these landmarks. It is possible to predict which types of species you will find on either side of the continental slope and the continental shelf.

The coral reef surveyors were instructed to find the best sites that they believed had the most living coral and were thought to be least affected by human activities. This would allow Hodgson to determine if human activities were having an appreciable effect on the supposed pristine coral reefs, which were distant from urban centers. The invertebrate survey was undertaken at two depth intervals of 3m and 10m. Four 0.5 m wide by 20 m long belts were placed on the coral reef. Over a period of 3-5 minutes the observers counted the number of invertebrates found on the belts. The coral survey was performed, by placing four 20 m long belts on the coral substrate. At 0.5 m intervals the substrate on which the belts were lying was examined and recorded.

The intertidal rocky shore of Caloundra Beach is inhabited by diverse range of biodiversity of animals and plants, many of which have developed high levels of adaptations throughout their existence. The very boundary of marine and terrestrial ecosystem, this environment is subjected to extremes of the physical environment such as temperature, desiccation, wave turbulence as well the ecological interactions that commonly occur in biotic communities (e.g. competition, predation). However Rocky intertidal shores are easily accessible by humans and provide an enjoyable opportunity for passive recreation and for science and environmental education as well.

The aim of this investigation is to look at the distribution of the ornate limpet, (Cellana Ornata) and the radiate limpet (Cellana Radians) on the rocky shore. We went to the rocky shore of Sirens rocks between Island Bay and Owhiro Bay, on Wellington’s South Coast. We are studying how our chosen organisms affect each other’s distribution patterns. We sampled in the low tide zone, mid tide zone, and high tide zone. The rocky shore we explored was 80 metre long, rocky terrain, bare rock platforms with rock gulley’s.

On the 9th of March, I went to Siren’s Rocks to investigate the community pattern, also called zonation, within the bounds of Island Bay’s Wellington Ecological Marine Reserve. The ecosystem of Taputeranga Marine Reserve takes the full impact of the Southern ocean swells. This Reserve is influenced by three different oceanic currents. This is an abiotic factor. The currents impact helps shape the rocky shoreline into the ecological community of different species of shore life into a pattern of different zones (zonation).
