The small tree-living mangrove ant Camponotus anderseni is remarkably adapted for surviving tidal inundation. By blocking the nest entrance with a soldier's head, water intrusion into the nest cavity can be effectively prevented, but lack of gas-exchange caused extremely high concentrations of CO(2)(>30%) and very low O(2) concentrations (<1%). The O(2) uptake in experiments with CO(2) absorption showed a linear decrease until about 4%, whereas the O(2) uptake in chambers without absorbent… CONTINUE READING
