how miserable: iNat seems to have abandoned the option to add a new area. Nor sure how I will add new areas above 2000m now. Need to generate a polyline and then KML file, but haven't been successful so far. If anyone could help, I'd be grateful. In the meantime, I will keep a checklist for items to be added. See below:
Needs to be added:
(1) Grindelwald - First (or entire area above 2000m which can be accessed by cablecars / trains)
This is a short study of the number of moth species (IDs on iNaturalist as of July 8, 2024) obtained by using LepiLED moth lights in 3 different places within the same ecological zone in Gadmental, BE, Switzerland, on July 5, 2024. The lights were placed in front of a wall or a rock, starting before dusk and visitied at around 3-4 a.m. to take pictures of all the moths. Lights could not be seen from each other and were placed on a stretch of 50-60m.
(1) "W" Tälli-Hütte, directly at W side of the house, South exposed, elevation 1700m
(2) "E" 20m East of Tälli-Hütte
(3) "EE" 50m East of Tälli-Hütte
The graph shows, that only 14 species were found in all three places! The species found in only one of the three places was reduced, compared to the investigation below. Conclusion: even if the light source, the weather and the ecozone seems identical, there is a significant difference between species caught. This is probably due to the statistics of "small numbers". If you'd observe over a long period of time, it would probably average out.
