Ocean Cores Lab Report

This experiment was a success. The experimental procedure from the lab manual was followed. The right materials needed for this experiment was also used. Each group recorded the data of the name of species and percent cover for species in the three transects. After, the class data was assembled, pie-charts and bar graph were drawn from the data using excel.

Explain how the ecosystem was affected by the missing species for each round of the demonstration.

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

5. According to your data, which two species that you identified diverged the longest time ago? Staph Aureus and Strep mutans

Read "Lab 3: Biodiversity." This lab will allow you to investigate how various organisms alter their environments. Additionally, it will allow you to assess the health of ecosystems based upon their biodiversity. Then, you will utilize this information and your eScience lab kit to complete Demonstration 1 and Experiment 1 on the Week Three Lab Reporting Form. Make sure to complete all of the following items before submission:

I examine how rising or falling tide can affect the water level of Corte Madera Salt Marsh in this report. The data is from Wednesday (June 19th) and Thursday (June 20th). My hypothesis is that tide and water level have positive relationship. From the result, I learn that the water level and tide have positive relationship. However, when tide changes its direction, the water level is likely to stay or little change.

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

Introduction: Almost every place on Earth, from the surface of your skin to the bottom of the ocean, is teeming with living things. To keep track of the vast diversity of life, biologists historically named and classified organisms according to their appearance. The system of categorizing organisms is

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

For the convenience of the students, a packet for recording the stream’s content and results was provided. On the first and second page, tables for seeing the taxa types of aquatic macroinvertebrates found were laid out, and students were to check the boxes with the names of the taxa they found in this area. Students entered the stream with a large water strain, and put dirt from the stream and carried it out of the stream to be examined. After observing several catches from the stream, the group one taxa findings included Stonefly nymph, Mayfly nymph, and Dobson fly nymph.

Which two organisms (species) from your sample had the lowest relative abundance? On what do these two

The nine specimens were placed into a watch-glass container and checked to ensure that they were of relatively equal sizes to one another. The pipette was then utilized to collect one Daphnia magna and placed onto a depression slide to create a wet mount. It is noted that a coverslip was not to be placed on the top of the slide.

The purpose of this study is to identify four unknown organisms. The unknown organisms have been assigned randomly to six-research groups by Professor Hoffman. Each research group was provided two eukaryotes and two prokaryotes. The unknown organisms will fall into the following classifications: bacteria, algae, fungi, or protozoans. All living organisms are organized into one of three domains of life, Bacteria, Archaea, and Eukarya.

Subclass Stichotrichia (Small & Lynn, 1985) Size, small to large; shape, often elongate, sometimes very drawn out posteriorly, in cross section round to dorsoventrally compressed; freeswimming with a few loricate forms; perilemma in some groups; pellicular alveoli weakly developed; somatic ventral ciliature as ventral cirri ranging from small and quite inconspicuous, occasionally as few as 2–3 cilia per cirrus, arranged in longitudinal, sometimes spiraled, files to a few, larger cirri in scattered groups, with in the latter case marginal files of cirri differentiated ; transverse cirri, may or may not be present; caudal cirri, may or may not be present; dorsal somatic ciliature as one to many kineties – typically three – of dikinetids without
