Note Fc: Average characteristic frequency (kHz) - the body of the call
is the portion of the call consisting of the flattest slope where the
characteristic frequency is typically the frequency at the latest part
of the call body; Sc: Average characteristic slope (Octaves per Second),
This is the slope of the body of the call, Positive values correspond to
decreasing frequency while negative values correspond to increasing
frequency; Dur: Duration of the call; Fmax: Maximum frequency detected
in the call (kHz); Fmin: Minimum frequency detected in the call (kHz);
Fk: Frequency at the beginning of the call body(kHz); Qual: Average
call quality (%), A measure of the smoothness of the call where smaller
values indicate a smoother call.
The distribution of bats varied among the regions studied. BLK had the
lowest number of species with only 18, while YZQ and YW had the highest
number with 24 species each (Table 2). In terms of horizontal
distribution, BLK had the highest latitude, followed by YW, and YZQ had
the lowest latitude. Regarding vertical distribution, the average
elevation of BLK and YW was similar, while YZQ had a lower average
elevation. The altitude distribution of various bat species varied. With
the exception of M. capaccinii and M. dasycneme , the other
five species of Myotis had an altitude range exceeding 1000 m,
indicating a broad altitude distribution. Among the species studied,Barbastella barbastellus , Hypsugo savii , andVespertilio murinus had the largest altitude distribution range.
With the exception of P. pipistrellus and P. pygmaeus , the
other two bat species were widely dispersed; Eptesicus andNyctalus bats had a limited altitude distribution. Tadarida
teniotis and Miniopterus schreibersii have comparable elevation
distributions but not much of a range; Within the genus Plecotus ,Plecotus bats have a very different distribution of altitude.
While P. auritus has a smaller altitude distribution, P.
austriacus has an altitude range of more than 1000 m.
