A Local Ecosystem Field Trip Report

Ecosystem Studied
The ecosystem studied on this field trip was a tidal rock-shelf in Long Reef.

Animal Distribution and Abundance across Three Different Locations.
Although all three animals represented in my graph above are found in the tidal rock-shelf ecosystem, their distribution is concentrated in certain areas in the ecosystem that they are more comfortable in.

The Little Blue Periwinkle is found in abundance in Location 1 and found slightly in Location 2, but not at all in Location 3. This shows that this organism will more likely be found in Location 1 although it can be found in Location 2.

The Mulberry Whelk was found in abundance in Location 3 and found slightly in Location 2, but not at all in Location 1. This shows that this organism will more likely be found in Location 3 although it can be found in Location 2.

The Waratah Anemone was found in abundance in location 2 and found slightly in Location 3, but not at all in Location 1. This shows that this organism will more likely be found in Location 2 although it can be found in Location 3.

Different Features of Each Location and its Affect on the Distribution and Abundance of the Organisms.
The three different locations used in my research were an area above high tide level, an area at the low tide level, and a tidal rook pool area.

The area above high tide level stays mostly dry for the majority of the day. During high tide however, this area may be sprayed with salt water depending how close it is to the high tide level. Because this area does not have much moisture, animals such as the Little Blue Periwinkle clump together in clusters to help prevent the loss of moisture.

The tidal rock pool area is a constantly changing environment. The water temperature, salinity, and oxygen content fluctuating with the tide. Because this area has a lot of...
