study sheet with different critters, and then the groups were free to explore the tide pools. Among the many critters observed including sea cucumber, jellyfish, clam worms, etc. the most interest/fascinating for me was the nudibranch and the shield limpet. My sister, the scientists and I spotted this little critter called a nudibranch in a tide pool.The nudibranch was fairly small, one to two inches long. Its coloring was much like that of a tigers, orange tentacles with black stripes. Afterwards
difference in limpet frequency at three different microhabitats at the middle shore – Rock pools, Under Rocks and on Top of Rocks. At each microhabitat six sites were investigated and the abiotic factors (temperature, humidity, wind speed and light intensity) were measured. It was found that Under Rocks had the highest frequency of limpets and Rock Pools had the lowest, this was because the limpets where sheltered from direct contact with sunlight and wind, so desiccation was less for limpets found under
==================== Animals ------- There are several clear trends in my results, the clearest of these being the limpet (Patella vulgata). The majority of limpets were situated mainly in the mid-littoral zone and splash zone. They had a peak at station 12 of 31 limpets. Their number slowly built up to this peak from 1 limpet at station 4 to 33 limpets at station 12. The limpets also petered out in numbers after station 12, to go 13 to 6 to 0. This tells me that they do not want to be exposed
In the following study, rock pools from the upper and lower shore of Bracelet Bay, were examined and the organisms within noted. The contents of the two pools were compared. The abiotic variations of the pools were recorded and examined in an attempt to understand why the contents of the pools differed. A greater abundance and variety of organisms was present in the lower shore rock pool, this was due to the lower rock pool being a more benign environment than that of the upper shore. This was
Always replace rocks. If you want to look under a rock, put it back the way it was when you 're done. Leaving a rock "belly-up" is an almost sure way to kill any animals that were living underneath it. Plan ahead. Look at tide charts to tell you when the best time to visit tide pools, it will give you a longer time to explore and a safer exit. Watch where you step. Barnacles and other tide pool dwellers will thank you for stepping carefully while you explore. Stay on bare rocks where you won’t crush
people’s diet. There is also a theory that part of the people’s diet was fish even though fish tackle has not yet been found. It is the discovery of stone boxes, with water-proof linings that suggested they needed a tank for fish bait, such as limpets. “Limpets are effective fish bait but they need to be softened before fish find them tempting. Soaking achieves this” (Clarke and Maggiore, 2000) Works Cited Childe, V. (1931). Skara Brae: A Pictish Villiage in Orkney (p. 15). London. Clarke
Rocky Shore Study Aim The aim of this investigation is to find where the lower, middle and upper zones on the rocky shore start and end by looking at the species present and absent in each zone. Apparatus 0.5m2 frame quadrat 2 marking poles Tape measure Method This investigation will be conducted when the tide is low on the rocky shore at Scarborough. In order to record a sample of the species along the rocky shore, an interrupted belt transect will be used to ensure
Barbara Kingsolver once said, I wrote The Bean Trees because Steinbeck wrote Cannery Row.” The novel, Cannery Row, crowded with various anecdotes, chases the ambitions of Mack and his group of eccentric men. However, the story incorporates little plot, instead, John Steinbeck is more interested in the community as a group. The meager town of Monterey, California conserves its sentimental value of fellowship and team effort. Although, the Row is established as a sluggish town, in reality its commoners
Investigating the Effects of An Abiotic Factor on the Frequency and Distribution of a Freshwater Invertebrate (i) Planning ------------ Introduction ============ Before a complex biological study can be planned and formulated, the terminology in the title above must be clarified. The investigation requires a sound knowledge of ecology, which essentially is the study of organisms, whether they be animals or insects, and their relationship with the environment in which they live
An Experiment to Investigate Species Diversity at West Runton Beach Aim === For this investigation, I am aiming to investigate the species diversity at West Runton Beach. The aim is to research the distributions of substrates, plant life and other organisms, comparing them with each other and relating it to the tidal zonation. This will hopefully show us how each factor of the environment affects the others. The experiment will be a line transect using a quadrant down to parts of
Name: Patrick Wrenn Take home Exam Anthropology 104: Biological Anthropology Answer all of the questions to the fullest. 1. What are the three types of speciation? Explain each. Allopatric: A new species evolves due to a geographic barrier (squirrels of the Grand Canyon). Parapatric: There is no specific extrinsic barrier to gene flow. Mating is more likely to happen between geographical neighbors than with organisms in different parts of the population’s range. A new niche in an existing
Spencer Stein Sarah Beck Oceanography 101 14 May 2018 The octopus genome and the evolution of cephalopod neural and morphological novelties This Jornal conducted research on the two-spot octopus, or Octopus bimaculoides, by sequencing the genome of this species. They found that “Coleoid cephalopods (octopus, squid and cuttlefish) are active, resourceful predators with a rich behavioural repertoire. They have the largest nervous systems among the invertebrates and present other striking morphological
Tidal and Wave Power Tidal power operates by building a barrier across a river estuary. The tidal flow drives turbines to produce electricity. Europe's only tidal power station is at Rance in Northern France. Some sites in the U.K could be developed to provide tidal power but the drawback is that these schemes affect the habitat of wildlife such as birds and fish because they alter the tidal currents. Also, barrage will only provide power for about 10 hours per day. Power for the other
In many aspects of our lives, the use of faith as a basis for knowledge can be found. Whether it is faith in the advice of your teacher, faith in a God or faith in a scientific theory, it is present. But what is faith? A definition of faith in a theory of knowledge context is the confident belief or trust in a knowledge claim by a knower, without the knower having conclusive evidence. This is because if a knowledge claim is backed up by evidence, then we would use reason rather than faith as a basis
She is sitting on the beach, alone. Her legs are curled under her, and her hands are feeling the pebbles at her side. They are smooth, like ducks' eggs. They fit snugly into her palm. The kind of pebble David used to kill Goliath, she thinks. She looks out over the sea. It is pewter, it is lead. The waves are bloated and sullen. They clutch at the shore and rasp as they retreat, surly as a kicked cur. The wet shore shines with the slug trail residue of the waves. The cliffs, honey and butter in sunshine
An ecosystem is an intricate set of relationships between the living resources, habitats, and residents living in an area. It is the biological community of countless interacting organisms and their physical environment. This includes plants, animals, macro and microorganisms, sea life, water, birds and people. There are three main types of ecosystems on planet Earth. These are the freshwater ecosystems, terrestrial ecosystems and ocean ecosystems (Northern Research Station, 2014). The Rocky Shore
With the help of international crews and scientist as well as post war era naval technologies, we’re able to finally find out what lies beneath the great oceans. In 1977, under the direction of Bob Ballard, a navigation group from Woods Hole Oceanographic Institute, Scripps Institute of Oceanography and researchers from Oregon State joined together aboard the Knorr. Over the Galápagos Rift with Alvin the world’s first deep-sea manned submersible they had plans to find such venting systems. At latitude
According to Campbell and Reece (2007) biogeography is the study of the past and present distribution of species. Cristopherson (1994) states that it is the study of the distribution of plants, animals and related ecosystems and the geographical relationships with related environments over time. It involves a wide range of disciplines such as biology, geology, geography and ecology. It begs the question, why are there so many more species in tropical rainforests than in woodlands? What allows a species
