The order Rodentia, the largest among mammals, includes 9 families, and the family Cricetidae is the most diverse of the Brazilian rodents. In Brazil, 12 of the 16 genera of\n                    <jats:italic>Oecomys<\/jats:italic>\n                    are found.\n                    <jats:italic>Oecomys bicolor<\/jats:italic>\n                    is known in Brazil as the \u2018arboreal rat\u2019 and is, found in dry, deciduous and tropical forests. The mean body weight of\n                    <jats:italic>Oecomys bicolor<\/jats:italic>\n                    was 35.8\u2009g and the gonadal, tubular and epithelial somatic indexes were, 0.53%, 0.47% and 0.37%, respectively. Seminiferous tubules volume density was 89.72% and the mitotic and meiotic indexes corresponded to 8.59 and 2.45 cells, respectively, and the yield of spermatogenesis was 23.83 cells. The intertubular compartment represented 10.28% of the testis parenchyma and around 5% of the interstitial space was occupied by Leydig cells, whose number per gram of testis was 11.10\u2009\u00d7\u200910\n                    <jats:sup>7<\/jats:sup>\n                    cells. By evaluating the biometric and histomorphometric characteristics of the testis, there is evidence that this species has a high investment in reproduction. Due to the high contribution of the seminiferous epithelium and the intertubular compartment in this species, compared to the others of the same family, it is possible to infer that the species\n                    <jats:italic>Oecomys bicolor<\/jats:italic>\n                    has a promiscuous reproductive behaviour.\n                  <\/jats:p>","DOI":"10.1111\/ahe.13062","type":"journal-article","created":{"date-parts":[[2024,6,4]],"date-time":"2024-06-04T17:26:57Z","timestamp":1717522017000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Testicular histomorphometric patterns and spermatogenesis dynamics of\n                    <i>Oecomys bicolor<\/i>\n                    tomes, 1860 (Rodentia: Cricetidae)"],"prefix":"10.1111","volume":"53","author":[{"given":"Ana Luiza Pereira","family":"Martins","sequence":"first","affiliation":[{"name":"Department of General Biology Federal University of Vi\u00e7osa  Vi\u00e7osa Minas Gerais Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6530-4684","authenticated-orcid":false,"given":"Fernanda Carolina Ribeiro","family":"Dias","sequence":"additional","affiliation":[{"name":"Department of Veterinary Federal Rural University of Pernambuco  Recife Pernambuco Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elizabeth Lopes","family":"Oliveira","sequence":"additional","affiliation":[{"name":"Department of General Biology Federal University of Vi\u00e7osa  Vi\u00e7osa Minas Gerais Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Grasielle Avelar Vieira","family":"Rodrigues","sequence":"additional","affiliation":[{"name":"Department of General Biology Federal University of Vi\u00e7osa  Vi\u00e7osa Minas Gerais Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gleide Fernandes","family":"de Avelar","sequence":"additional","affiliation":[{"name":"Departament of Morphology Federal University of Minas Gerais  Belo Horizonte Minas Gerais Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fabiana Cristina Silveira Alves","family":"de Melo","sequence":"additional","affiliation":[{"name":"Department of Animal Biology Federal University of Vi\u00e7osa  Vi\u00e7osa Minas Gerais Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kyvia Lugate Cardoso","family":"Costa","sequence":"additional","affiliation":[{"name":"State University of Minas Gerais  Carangola Minas Gerais Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S\u00e9rgio Luis Pinto","family":"da Matta","sequence":"additional","affiliation":[{"name":"Department of General Biology Federal University of Vi\u00e7osa  Vi\u00e7osa Minas Gerais Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,6,4]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/aja.1001100107"},{"key":"e_1_2_10_3_1","volume-title":"Avalia\u00e7\u00e3o morfofuncional do test\u00edculo e do processo espermatog\u00eanico dos roedores silvestres Akodon cursor e Oligoryzomys nigripes (RODENTIA: Cricetidae)","author":"Balarini M.
