- Fig. 1. Sonogram of a signal by a russet ground squirrel warning of danger and its frequency
- Fig.2. Studied populations (markers) and population groups (metapopulations, ellipses) of russet ground squirrels in the right-bank Volga region and adjacent territories.
- Fig. 3. Results of step-by-step discrimination analysis of bioacoustics indicators samples of screams warning of dangers which characterize population groups (metapopulations) of russet ground squirrels of the Middle Volga region and adjacent territories.
- Table. 1. Bioacoustic indicators of russet ground squirrels’ populations in the right-bank Volga region and adjacent territories
- Table. 2. End of table 1
- Table. 3. Bioacoustic indicators of russet ground squirrels’ population groups (metapopulations) in the right-bank Volga region and adjacent territories. Maximum values of indicators are highlighted with dark grey, minimal with light grey. Labelling is as in Table 1
- Table. 4. Results of comparing the samples characterizing spatial population groups (metapopulations) of russet ground squirrel in the right-bank Volga region and adjacent territories. The left lower part of the table presents trades-off (1 – Fнач, 2 – Fмакс, 3 – Fмин, 4 – Hмод, 5 – D 1 , 6 – D 2 , 7 – D 3 , 8 – D общ) on the results of Bonferroni’s test whereas the right uppers part – on the results of LSD test. Labelling of spatial population groups and bioacoustics indicators is the same as in Table 1
