Palaeoecological techniques

Raised peatbogs, such as the ones employed in the PATAGON project are constantly evolving systems – the plants and animals that live and grow on their surfaces changes in response to the environmental conditions.

As bogs accumulate over time, fragments of plant material and microscopic organisms called testate amoebae are preserved in the acidic conditions. Examining how these plants and animals have changed over time gives us an insight into how the climate may have varied in the past.
