Genetically distinct ecomorphs emerge in a mosaic, forming local centers of biodiversity. The mechanisms behind this process are of particular interest, as they facilitate the study of speciation. Here we examine the patterns of evolution in the endemic charrs (genus\n                    <jats:italic>Salvelinus<\/jats:italic>\n                    ) that populate the Kronotskoe\u2010Uzon drainage system. This is one of the most phenotypically diverse and complicated assemblages of salmonids on Earth. By analyzing SNPs in SLAF sequences of 107 specimens covering all local diversity and 55 specimens from nine populations of the potential ancestor, we investigated the phylogenetic relationships, the timeline of diversification, genetic structure, and historical gene flow within the population system. Our findings suggest that the endemic assemblage diverged from the widespread anadromous\n                    <jats:styled-content style=\"fixed-case\">\n                      <jats:italic>Salvelinus malma<\/jats:italic>\n                    <\/jats:styled-content>\n                    of eastern Kamchatka, which probably invaded the basin in several waves. Ten of the 14 genetically distinct ecomorphs diversified in Lake Kronotskoe at the center of the drainage system. The assemblage formed in the post\u2010LGM\u2014Holocene time as a result of inter\u2010lake multistep adaptive radiation and specialization of hybridogenic populations, as well as the secondary expansion of endemic charrs into peripheral waterbodies. The steps of ecomorph divergence coincide well with the main geological and paleoclimatic events in the area. Although the diversity of Kronotskoe\u2010Uzon charrs is unique, faunal radiation has proceeded through several archetypal ecological modes implemented by freshwater fishes in dozens of reservoirs across the Holarctic. The reason for this increased diversity is the active habitat restructuring and enhanced ecological opportunities provided by the large lake\u2013river system in the moderate climate.\n                  <\/jats:p>","DOI":"10.1002\/ece3.74339","type":"journal-article","created":{"date-parts":[[2026,9,23]],"date-time":"2026-09-23T10:48:33Z","timestamp":1790160513000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Patterns of Evolutionary Diversification in a World\u2010Significant Hotspot of Salmonid Diversity: A Study of Landlocked\n                    <i>Salvelinus<\/i>\n                    Fish of the Kronotskoe\u2010Uzon Area, Kamchatka"],"prefix":"10.1002","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1200-6464","authenticated-orcid":false,"given":"Evgeny V.","family":"Esin","sequence":"first","affiliation":[{"name":"Vitus Bering Kamchatka State University  Petropavlovsk\u2010Kamchatsky Russia"},{"name":"A.N.
