'Ecology' : The study of the relationships between living things and their environments.
This is a collection of images with the world of nature on Arran as a subject matter, from plants to birds and sea life to sea weed.
Found this frog in the undergrowth and straight away he went so still, pretending to be one of the leaves. They have adaptive camouflage and his colour changed to the red brown of the dead leaf litter. I sat for a couple of minutes to see if he would move but this wee guy was definetly out to convince me he was a leaf!
