Allume - Steep coast
The diagram shows the distribution of recorded ultrasonic calls during the night of 8 to 9 May 2023 in the Allumne. It shows the temporal distribution of call frequencies from the first to the last recorded call. Based on the frequency ranges, three main call groups can be identified:
- Nyctaloids (blue): Frequencies up to about 30 kHz, which can be assigned primarily to the species Nyctalus lasiopterus and Tadarida teniotis.
- Pipistrellus species and Hypsugo savii (red): Calls in the range up to approx. 52 kHz attributed to this species group.
- Lesser horseshoe bat (orange): Calls with frequencies around 100 kHz that can be clearly attributed to Rhinolophus hipposideros.
The diagram illustrates the different frequency and distribution of call activity throughout the night. The temporal distribution of the calls indicates continuous hunting activity throughout the night.
Conclusion
The Pipistrellus call group was detected in all habitats studied and showed the highest activity, with the most call recordings. Different species can probably be differentiated here, but it is certain that the white-edged bat(P. kuhlii) is present. The Allume cliff showed the highest species diversity, which is due to the diverse structures and transition areas between maquis, cliff and holm oak forest. These semi-open areas offer both ample hunting opportunities and suitable roosting sites. It was also found that small bodies of water also favour a high diversity of species.
