On Wednesday the 18th February the year 12 biology class went to Siren 's Rock between Island bay and Owhiro bay to study community patterns. The community pattern we were studying was zonation on the rocky shore. Zonation is when an environmental factor changes, the distribution of species changes which results in the species being present in zones or bands. In this report I am going to talk about the Cellana denticulata limpet, the Cellana radian and the relationship between the two species. Species 1: Description: The Cellana denticulata is a limpet which belongs in the true limpet family. A true limpet is a small marine gastropod mollusc. The C denticulata is a mollusc due to it having a soft body with a hard shell. The shell of the C denticulata is a lot more elevated and bigger than other species of limpets with 20-30 strong ribs granulose and scaly. The colour of the shell can vary from a grey to brown colour. On the inside of the shell the C denticulata is a bluish whitey colour with darker streaks where the undersides of the ribs are. The C denticulata has a strong muscular foot on the underside of their body which allows it to suction itself onto the rock to prevent slipping or falling from the rock. This limits the movements of where the C denticulata can travel as they cannot move in large distances. This means when it comes to feeding the C denticulata doesn 't travel very far. They are algae grazers, which graze when the tide is in by scraping the algae off
Habitat: Commonly found in terrestrial. Forest light gaps, slips, margins, disturbed sites, open habitats, riverbeds, cliffs, inshore and offshore islands, fernland, herbfield,
The species randomly settle throughout the rock. Both species are settled at the bottom and top. They settle on same parts of the rocks as the other species did. There is more of an abundance of the Chthamalus than the Semibalanus.
Zonation is the distribution of animals and plants into specific zones according to abiotic factors and characterised by its dominant species [15]. Mangrove zonation is the distinguishable categorisation of a mangrove ecosystem that extends from shore to inland regions. Definitive spatial variation of mangrove species has been recognised amongst different ecosystems worldwide and is accredited as being influenced by abiotic and environmental factors [16]. In Eastern Australia, the majority of mangrove forests may be divided into landward, middle and seaward zones, based off of their placement in relation to tidal position. The following points represent the typical physiognomies characterised by mangroves in their corresponding zones:
“More repairs to the lighthouse were in the works when the American Revolution intervened. In July 1775, Boston Harbor and the lighthouse were under the control of the British. On July 20, American troops under Major Joseph Vose landed at the lighthouse and took lamps, oil, and some gunpowder, and burned the wooden parts of the tower. After leaving the island they had to outrun an armed British schooner, and two Americans were wounded. An eyewitness described “the flames of the lighthouse ascending up to Heaven, like grateful incense, and the ships wasting their powder.”
The scientific name of this organism is Fisherola Nuttalli. The Columbia River Limpet is a small lunged (pulmonate) snail. According to an article by Celeste Mazzacano at the Xerces Society for Invertebrate Conservation (http://www.xerces.org/giant-columbia-river-limpet/), “It has a limpet-like appearance, with an uncoiled conical shell that has a wide base and a smooth, eccentric (off-center) apex. The shells may reach up to 8 mm long, 6.25 mm wide, and 3 mm high; they are rich brown in color and appear striped due to fine concentric growth rings (Neitzel & Frest 1992).” This organism is known as an invertebrate due to the lack of a backbone. Invertebrates lack a vertebral column, which is made up of bones called vertebrae. The scientific name for animals lacking a backbone is Invertebrata. On the other hand, animals with a backbone are known as vertebrates, the scientific name being Vertebrata. There are over 1
First, this mainly due to the fact that O’ahu tree snails have unique colorful shells, and as a result, many people are removing these snails and using them for scientific studies or cases (Kay and Hadfield, 1972). In other words, the snails are being taken away from their natural habitat and kept in laboratories for scientific studies. However, most humans are not aware that they are disturbing their environment and having a negative impact on the overall population of Achatinella mustelina. Moreover, many shell collectors and nature enthusiast in the late 1800s and early 1900s collected these Achatinella mustelina because of their colorful, flamboyant and patterned shells which in return negatively impacted the number of these specimen (Hadfield 1986, Hadfield et al. 1993). For this, shell collectors and nature fanatics have to be aware and appreciative of the impact and effect that wildlife animals have on the environment as well as the ecosystem as a whole. In other words, when human forces disturb a species habitat or environment, they are negatively impacting the ecosystem thus increasing the extinction rate of endangered
The Naracoorte caves provides plenty of information about the history during the Pleistocene era. In terms of a scientific understanding, Palaeontologists have excavated and dated many of the fossils in Naracoorte Caves and have reconstructed the skeletons of a number of the megafauna that inhabited the area so many years ago. This gives them a better understanding of the evidence supporting Australia’s changing environment, climate and fauna and how each of these contributing factors have played a major role in the extinction of these megafauna's. With the reasons provided, the protection of the Naracoorte caves is essential as the caves holds many scientific evidence and fascinating values as well as Australia's record of
Under the Wave off Kanagawa is part of a series of prints titled Thirty-six views of Mount Fuji, which Hokusai made between 1830 and 1833. It is a polychrome (multi-colored) woodblock print, made of ink and color on paper that is approximately 10 x 14 inches. All of the images in the series feature a glimpse of the mountain, but as you can see from this example, Mount Fuji does not always dominate the frame. Instead, here, the foreground is filled with a massive cresting wave. The threatening wave is pictured just moments before crashing down on to three fishing boats below. Under the Wave off Kanagawa is full of visual play. The mountain, made tiny by the use of perspective, appears as if it too will be swallowed up by the wave. Hokusai’s
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.
“Rosette was born the same day that Gambo disappeared. That is how it was. Rosette helped me through the worry that they would take him alive and with the emptiness he left in my heart. I was absorbed in my daughter. That Gambo was running through the jungle pursued by Cambray 's dogs occupied only a part of my thoughts” (Allende, 134) Those words are said by Zarité, the main character of the book Island Beneath the Sea by the Chilean Isabel Allende, translated and published in the United States on 2009. It starts on the Island of Saint-Domingue (actual Haiti) from 1770 to 1793 and the second part, take place on Louisiana, USA, from 1793 to 1810. About the main character, Allende said: "Of all the characters I created, that of Zarité for me that I have more the feeling that existed". While Island beneath the Sea, I have been clarifying, predicting and finally, evaluating.
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).
Limpets (Patella vulgate) live in algae rich environments on rocky shores. They feed on the algae and try to defend areas where algae grow against other limpets and other species that are competing for the food source (e.g barnacles and mussels). Limpet shells

Would you read a book about adventure, survival and brotherhood? What if it was about humanity and nature? Now, what if it involved bunnies? Watership Down is an award winning book by Richard Adams. Described as ‘redefining anthropomorphic fiction’ by critics, the book won both the Carnegie medal and the Guardian children’s prize. Tackling big ideas, the author weaves an adult tale of human struggle disguised as a book about bunnies. Besides granting the powers of speech and intellect, he has gifted his rabbits with trembling fears, clownish wit, a folklore of proverbs and poetry, and a language called Lapine, complete with a glossary!
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.
