Fig. 4 in Changes In The Structure Of Nest Complexes Of The Red Wood Ants Formica Rufa And F. Polyctena (Hymenoptera, Formicidae) In Urban Forests
Fig. 4. Degradation of the Formica rufa complex No. 1 (Feofaniya) in terms of average height (4, A) and diameter (4, B) under conditions of intensive construction and recreation; 4, С, D — diameter and height near the nest complex of F. polyctena No. 4 (surroundings of the Observatory), under conditions of felling of the shrub layer and processing of fallen trunks and branches into wood chips.
Figure 4 in Changes In The Structure Of Nest Complexes Of The Red Wood Ants Formica Rufa And F. Polyctena (Hymenoptera, Formicidae) In Urban Forests
Figure 4 shows the degradation trends for the nest complexes of F. rufa No. 1 (4, A, B), F. polyctena No. 4 (4, C, D). For F. rufa No. 1, there was a sharp decrease in the average diameter of anthills in 2014, and on the contrary, an increase since 2015 (fig. 4, A). In 2016, this indicator remained at approximately the same level, and in 2021 it decreased again. In 2022, this nest complex

Fig. 8 – a, Spatial distribution of mapped RWA nests in FBBSF based on the 1m DTM provided by the LDBV (2008/2009). Black square indicates a striking radial nest distribution pattern that can be explained by b, "onion-like" joints forming in the granite, as can be seen in the former quarry beneath the ruin Flossenbürg castle, approx. 14.5 km southeast of the FB Study area.
