Red wood ants (Formica rufa group) are common in many European forests. Because of their wide occurrence wood ant social structure, geographical distribution, population dynamics, and biodiversity have been intensively studied. Wood ants build large above-ground nests (mounds) composed of litter (needles, twigs, resin) collected from the surrounding forest stand, and potentially have a large impact on soil carbon (C) and nutrient cycling in forest ecosystems. However, our knowledge on the impact of wood ants on forest C and nutrient cycling is very limited. While the dissertation of Anita Risch is investigating above and below-ground carbon and nitrogen pools in subalpine forests, this study should help to provide a better understanding of other potential C and nutrient sinks and sources in an ecosystem. Consequently, the objectives of our study are to: 1) quantify C and nutrient pools in wood ant mounds of subalpine conifer forests; and 2) assess annual CO2 emissions from ant mounds in forests of different ages. Our experimental approach will be to determine the number, size, and C/nutrient pools of wood ant mounds in representative subalpine conifer stands. Outputs (CO2 emissions, nutrient mineralization) will be measured and compared to the surrounding forest floor and mineral soil.
