We evaluated 59 microsatellite loci previously described for other primates, including humans, of which 16 were polymorphic. A total of 81 individuals were genotyped, comprising 33 tissue samples from rescue centers, 3 from capture for radiocollar placement, and 45 non\u2010invasive fecal samples from two wild populations: Yacutinga Reserve (Fragmented Forest, FF) and the Urugua\u2010\u00ed\u2010Forester Biological Corridor (Continuous Forest, CF). Structure analysis identified an optimal value K\u2009=\u20093, revealing three major genetic ancestry components with varying degrees of admixture across populations rather than discrete lineages. These components correspond to: (1) a distinctive Continuous Forest (CF) component, (2) a distinctive Yacutinga Fragmented Forest (FF) component, and (3) a widespread background component occurring throughout Misiones Province, which represents the entire distribution range of the species in Argentina. Notably, the CF population exhibited the highest genetic variability, whereas FF showed the lowest. Isolation\u2010by\u2010distance analysis via the Mantel test revealed no significant relationship between genetic and geographic distances (R\u2009=\u20090.0336;\n p<\/jats:italic>\n \u2009=\u20090.299), suggesting that genetic differentiation may be driven by habitat fragmentation and landscape characteristics rather than geographic distance alone, though historical demographic dynamics may also contribute to these patterns. These results emphasize that forest fragmentation negatively impacts the genetic health of\n S. n. cucullatus<\/jats:italic>\n and underscore the urgent need to maintain and restore biological corridors to ensure long\u2010term genetic viability in the fragmented landscape of Misiones.\n <\/jats:p>","DOI":"10.1002\/ajp.70213","type":"journal-article","created":{"date-parts":[[2026,10,5]],"date-time":"2026-10-05T11:27:42Z","timestamp":1791199662000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Genetic Diversity and Population Structure of the Southern Black\u2010Horned Capuchin (\n Sapajus nigritus cucullatus<\/i>\n ) in Argentina"],"prefix":"10.1002","volume":"88","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1751-6313","authenticated-orcid":false,"given":"Luciana I.","family":"Oklander","sequence":"first","affiliation":[{"name":"Grupo de Investigaci\u00f3n en Gen\u00e9tica Aplicada (IBS\u2010UNaM) \u2013 Consejo Nacional de Investigaciones Cient\u00edficas y T\u00e9cnicas (CONICET) Posadas Argentina"},{"name":"Neotropical Primate Conservation Argentina Puerto Iguaz\u00fa Misiones Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-4143-9851","authenticated-orcid":false,"given":"Victoria Martinez De","family":"Zorzi","sequence":"additional","affiliation":[{"name":"Grupo de Investigaci\u00f3n en Gen\u00e9tica Aplicada (IBS\u2010UNaM) \u2013 Consejo Nacional de Investigaciones Cient\u00edficas y T\u00e9cnicas (CONICET) Posadas Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3118-4071","authenticated-orcid":false,"given":"Mariela","family":"Caputo","sequence":"additional","affiliation":[{"name":"Universidad de Buenos Aires, Facultad de Farmacia y Bioqu\u00edmica, Centro de Referencia en Identificaci\u00f3n Humana \u2010 Servicio de Huellas Digitales Gen\u00e9ticas, Consejo Nacional de Investigaciones Cient\u00edficas y T\u00e9cnicas (CONICET) Buenos Aires Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0633-3482","authenticated-orcid":false,"given":"Dante L.","family":"Di Nucci","sequence":"additional","affiliation":[{"name":"Neotropical Primate Conservation Argentina Puerto Iguaz\u00fa Misiones Argentina"},{"name":"Fundaci\u00f3n de Historia Natural F\u00e9lix de Azara Centro de Rescate y Conservaci\u00f3n de Fauna Silvestre G\u00fcir\u00e1 Oga Puerto Iguaz\u00fa Misiones Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9283-2071","authenticated-orcid":false,"given":"Gimena","family":"Illia","sequence":"additional","affiliation":[{"name":"Neotropical Primate Conservation Argentina Puerto Iguaz\u00fa Misiones Argentina"},{"name":"Estaci\u00f3n Biol\u00f3gica Corrientes (EBCo), Centro de Ecolog\u00eda Aplicada del Litoral (UNNE) Consejo Nacional de Investigaciones Cient\u00edficas y T\u00e9cnicas (CONICET) San Cayetano Corrientes Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0064-467X","authenticated-orcid":false,"given":"Sandro L.","family":"Bonatto","sequence":"additional","affiliation":[{"name":"PUCRS \u2010 Pontif\u00edcia Universidade Cat\u00f3lica Porto Alegre Rio Grande do Sul Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Corach","sequence":"additional","affiliation":[{"name":"Universidad de Buenos Aires, Facultad de Farmacia y Bioqu\u00edmica, Centro de Referencia en Identificaci\u00f3n Humana \u2010 Servicio de Huellas Digitales Gen\u00e9ticas, Consejo Nacional de Investigaciones Cient\u00edficas y T\u00e9cnicas (CONICET) Buenos Aires Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,10,5]]},"reference":[{"issue":"1","key":"e_1_2_9_2_1","doi-asserted-by":"crossref","first-page":"28","DOI":"10.1111\/j.1755-0998.2008.02387.x","article-title":"Two\u2010Step Multiplex Polymerase Chain Reaction Improves the Speed and Accuracy of Genotyping Using DNA From Noninvasive and Museum Samples","volume":"9","author":"Arandjelovic M.","year":"2009","journal-title":"Molecular Ecology Resources"},{"key":"e_1_2_9_3_1","doi-asserted-by":"crossref","unstructured":"Di Bitetti M.
