Nest Structure and Hibernation Adaptations of Formica forsslundi (Hymenoptera, Formicidae) Ants on Peat Bogs
Аннотация
The ant species Formica forsslundi is stenotopic, being known for its disjunct distribution and association with oligotrophic habitats such as peat bogs. There is also evidence of nest complexes and nest-building of F. forsslundi in sandy soil conditions. Our study presents a different interior nest structure and morphology related to peat bog characteristics. We describe four types of anthill based on their shape, seasonal exploitation, location and tunnel system. Two of these types are major nests containing ants all over the year, whereas the other two are auxiliary, used only in the summer. According to this and foraging activity data, we suggest that F. forsslundi ants meet the criteria of obligate social polycaly, unlike an earlier viewpoint proposing diffusive or closed polycaly. Moreover, we located the hibernation places, either turf cavities or specific chambers in the middle of the nest.
