‘Costa Rica – a special relationship’

In this presentation I investigate a whole range of associations that exist between organisms in the rainforests of Costa Rica. From predator – prey relationships and parasitism  to mutualism and commensalism – and lots of other associations  which aren’t too easy to define! When you consider that army ants have been found to have over 550 organisms associated with them …………300 or so of which are totally dependent on their ant ‘friends’ you can understand just how complex this special relationship is !
