Ecological niche dynamics have profound implications for speciation and species distributions, yet remain underexplored in freshwater organisms. Here, we investigated ecological niche variation among clades of\n                    <jats:italic>Aegla<\/jats:italic>\n                    (Aeglidae), a diverse freshwater crustacean genus endemic to southern South America, to uncover links between niche differentiation and lineage diversification. Using MaxEnt to build niche models with climatic and elevation variables, we assessed niche overlap and similarity in environmental space via PCA\u2010env, Hellinger's\n                    <jats:italic>I<\/jats:italic>\n                    , and Schoener's\n                    <jats:italic>D<\/jats:italic>\n                    metrics, complemented by equivalence and similarity tests. We found pronounced niche divergence among\n                    <jats:italic>Aegla<\/jats:italic>\n                    clades, characterized by distinct climatic preferences and low\u2010to\u2010moderate pairwise overlap. Niche equivalence tests rejected conservatism in all comparisons. This divergence is consistent with the combined effects of geographical isolation among drainage basins and regional climatic heterogeneity, which may have restricted dispersal and promoted the independent occupation of contrasting environmental conditions. These patterns suggest that ecological differentiation, together with historical geographic isolation, is closely associated with diversification within the group. Our results demonstrate that ecological adaptation has likely contributed to diversification in\n                    <jats:italic>Aegla,<\/jats:italic>\n                    highlighting niche divergence as an important component of freshwater biodiversity. These insights emphasize the sensitivity of such taxa to ongoing environmental changes and advance our understanding of ecological processes in shaping evolutionary patterns in South American aquatic systems.\n                  <\/jats:p>","DOI":"10.1002\/ece3.74344","type":"journal-article","created":{"date-parts":[[2026,9,11]],"date-time":"2026-09-11T13:33:11Z","timestamp":1789133591000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Niche Divergence in the South American Freshwater Crustacean\n                    <i>Aegla<\/i>\n                    Provides Insights Into Its Diversification"],"prefix":"10.1002","volume":"16","author":[{"given":"Gislaine","family":"Puli","sequence":"first","affiliation":[{"name":"Programa de P\u00f3s\u2010gradua\u00e7\u00e3o em Biodiversidade Animal, Centro de Ci\u00eancias Naturais e Exatas, Universidade Federal de Santa Maria  Santa Maria Rio\u00a0Grande do Sul Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u00c1lvaro Augusto","family":"Mainardi","sequence":"additional","affiliation":[{"name":"Programa de P\u00f3s\u2010gradua\u00e7\u00e3o em Biodiversidade Animal, Centro de Ci\u00eancias Naturais e Exatas, Universidade Federal de Santa Maria  Santa Maria Rio\u00a0Grande do Sul Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H\u00e9llen","family":"Sbruzzi","sequence":"additional","affiliation":[{"name":"Programa de P\u00f3s\u2010gradua\u00e7\u00e3o em Biodiversidade Animal, Centro de Ci\u00eancias Naturais e Exatas, Universidade Federal de Santa Maria  Santa Maria Rio\u00a0Grande do Sul Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sandro","family":"Santos","sequence":"additional","affiliation":[{"name":"Programa de P\u00f3s\u2010gradua\u00e7\u00e3o em Biodiversidade Animal, Centro de Ci\u00eancias Naturais e Exatas, Universidade Federal de Santa Maria  Santa Maria Rio\u00a0Grande do Sul Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4837-8219","authenticated-orcid":false,"given":"Marlise Ladvocat","family":"Bartholomei\u2010Santos","sequence":"additional","affiliation":[{"name":"Programa de P\u00f3s\u2010gradua\u00e7\u00e3o em Biodiversidade Animal, Centro de Ci\u00eancias Naturais e Exatas, Universidade Federal de Santa Maria  Santa Maria Rio\u00a0Grande do Sul Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,9,11]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcz.2025.07.005"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.11646\/zootaxa.5418.4.5"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.es.18.110187.002421"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0037105"},{"key":"e_1_2_10_6_1","first-page":"1","volume-title":"Aeglidae: Life History and Conservation Status of Unique Freshwater Anomuran Decapods","author":"Bartholomei\u2010Santos M.
