To investigate the types of producers and animals in the tidal rock-shelf ecosystem and the adaptations of organisms in that environment.
Also, to measure biotic and biotic components and the distribution and abundance of organisms to the tidal rock- shelf ecosystem. Introduction: Long Reef Marine Reserve was established in the sass’s to protect the extremely diverse marine life that makes the most of this environment. The Marine reserve covers the large rocky peninsula and the neighboring rock platforms betweenLong Reef and Collar beaches on Kidney’s North Shores. The date of the field trip to investigate Long reef marine reserve was the 4th of April. Materials Used to Collect Data: – Transect Marker String Thermometer – Refractors – Quadrate – Universal Indicator – Four Sample Bottles Method: During the Field Trip, a range of sampling techniques were used to collect various biotic and biotic data. This included Transects, Quadrate, Salinity and pH Levels, and The Temperature of various areas.
– A Transect line was used to take a random sample of organisms that occur on the loping rock on the edge of the rock platform.Organisms generally occupy and dominate specific zones. This sampling technique was carried out by constructing a line transect to examine the rock platform from an area of extreme low tide to an area of extreme high tide. Starting at the mm mark the dominant organisms were identified at each meter. This information was graphed on a diagram. – A Quadrate was used to measure the distribution and abundance of the Tidal Rock- shelf Animals.
The mm squared Quadrate was randomly placed at three different actions that were being investigated, these locations included Above the High Tide Mark, Tidal Rock Pool and Below Low Tide.The various species of Organisms Within the Quadrate were identified and their number recorded. This information provided an estimation of the distribution and abundance of various species in a particular area. – The Salinity levels of both the ocean and the Tidal Rock pools were recorded by collecting samples of water in both areas in marked containers. Using a refractors, the salinity of both samples of water were recorded and the amount of alt per liter of water were read in grams.The salinity levels of the rock pools and the ocean can determine which organism are able to survive in this environment, it also determines a range of other factors.
– The pH levels to boot the ocean and rock pools were recorded by collecting samples of both types of water in separate containers. A Universal Indicator was used to determine the pH of both the Rock Pools and the Ocean. – The most basic sampling technique used was the recording of The temperature of the ocean, the rock pools and the air.
A thermometer was used to record this information.The temperature of these areas determine a range of factors about the rock pools and the organisms that have to live in these areas and adapt to various changes. Estimation Of the Populations Nobly winks in the Supra Littoral Zone – Nobly Winks = 68/ meter squared – Supra- Littoral Zone = 1200 meters Squared Therefore, estimation of Nobly winks in the supra- littoral zone is 81,600 nobly winks. Barnacles in the sub -Littoral Zone – Barnacles = 96/ meter squared – sub littoral Zone = 800 meters squared Therefore, the estimation of Barnacles in the sub littoral zone is 76, 800 barnacles.
