Ecology continues, we have been looking in some depth at the concept of an organisms niche. One of our main focusses for this part of our course it be able to explain and discuss why organisms live where they do and how they interact with the other organisms living in the same environment. One way ecologist's have sought to interpret this is the concept of an organisms realised niche compared to it's potential niche.
This link explains it quite simply.
We have also been back out with our quadrants to do some more sampling of plant communities this time on the front lawn. On this site there is an environmental gradient where the large trees shade the lawn close to the stone fence and as we move to the middle of the lawn it is in full sunlight. In the shady area we find a weed known as
Hydrocotyle but this is much less common in the middle of the lawn.
