A robust phylogeny showed four strongly supported genus-level clades corresponding to &lt;i&gt;Physella&lt;/i&gt;, &lt;i&gt;Physa&lt;/i&gt;, &lt;i&gt;Stenophysa&lt;/i&gt; and &lt;i&gt;Aplexa&lt;/i&gt;. &lt;i&gt;Physella acuta&lt;/i&gt; thrives in continental African countries and Indian Ocean islands. The African continent was colonised at least six times independently.&lt;/p&gt;\u0000 \u0000 &lt;p&gt;For &lt;i&gt;Stenophysa&lt;/i&gt;, the phylogeny suggests two independent transoceanic dispersal events into Africa and the Indian Ocean islands. &lt;i&gt;Physella acuta&lt;/i&gt; occurs not only in artificial or highly disturbed habitats but also in large natural lakes. &lt;i&gt;S&lt;/i&gt;&lt;i&gt;tenophysa&lt;/i&gt; &lt;i&gt;marmorata&lt;/i&gt; is ecologically flexible. The SDM for &lt;i&gt;S. marmorata&lt;/i&gt; based on the selected climate variables predicted high probabilities of future occurrence in equatorial Africa and regions in the Indo-Malayan Archipelago, New Guinea and eastern Australia.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Main Conclusions&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Physidae contains examples of both intraspecific cryptic and interspecific cryptic invasions, with an intraspecific invasion of &lt;i&gt;Physella acuta&lt;/i&gt; and a prime example of an interspecific cryptic invasion of &lt;i&gt;Stenophysa&lt;/i&gt; spp. This study highlights the importance of cryptic invasions in freshwaters and also calls for their management. &lt;i&gt;Stenophysa&lt;/i&gt; is likely to become pan-tropical in the future.

Given the conservation challenges faced by these species, it is crucial to understand their phylogenetic relationships and suitable habitats in order to implement effective conservation strategies. In this study, we integrated phylogeny and Ecological Niche Modelling (ENM) techniques to investigate the conservation biogeography of mountain vipers.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Location</h3>\u0000 \u0000 <p>Irano-Anatolian, Caucasus and Levant.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>We first reconstructed phylogenetic tree of the species, and then, by using a set of occurrence records of the identified clades and environmental variables we modelled ecological niche of the species using the MaxEnt model and PCA-env analysis.
