The distribution situation of the rock ptarmigan can be assigned to allopatric speciation. Allopatric speciation occurs when a population is geographically isolated from others of its species, leading to reproductive isolation and the eventual evolution of distinct species. In the case of the rock ptarmigan, their distribution across different mountain ranges has likely led to isolation and the development of unique characteristics in each population, contributing to speciation. **

The distribution situation of the alpine ptarmigan can be assigned to allopatric speciation. This is because the alpine ptarmigan populations are isolated in different mountain ranges, leading to genetic divergence and the formation of distinct species. The geographic isolation of these populations prevents gene flow between them, leading to the evolution of unique traits and adaptations in each population. This process ultimately results in the formation of new species. **

However, it is important to check the specific entry and transit requirements of the country in question, as rules may vary. **

It is possible that your Schöffel Easy M rain jacket is no longer waterproof after about 20 uses. Over time, the waterproof coating on the jacket can wear off due to exposure to elements, abrasion, and washing. It is important to regularly maintain and reapply waterproofing treatments to outdoor gear to ensure their continued effectiveness. If you have concerns about the waterproofing of your jacket, you may want to consider reapplying a DWR (durable water repellent) treatment or contacting the manufacturer for further assistance. **
