It breeds year-round, with an average litter size of 3.5.[1] Individuals may be diurnal or nocturnal and solitary or social depending on season, habitat and hunting pressure.[1] This species is reported to be common in Panama but rare in Venezuela.[1] It is threatened by subsistence hunting, the destruction of gallery forests and swamp drainage, specifically the swamp drainage of the Magdalena River.[1] Its karyotype has 2n = 64 and FN = 104.[3][4] References1. ^1 2 3 4 {{cite journal | authors = Delgado, C.; Emmons, L. | title = Hydrochoerus isthmus | journal = IUCN Red List of Threatened Species | volume= 2016 | page = e.T136277A22189896 | publisher = IUCN | year = 2016 | url = https://www.iucnredlist.org/species/136277/22189896 | doi = 10.2305/IUCN.UK.2016-2.RLTS.T136277A22189896.en | accessdate = 20 October 2018}}[https://web.archive.org/web/20180602134856/http://www.iucnredlist.org/details/136277/0 (previous version)] {{Caviidae nav}}{{Taxonbar|from=Q1040804}}{{rodent-stub}}2. ^Hydrochoerus isthmius (lesser capybara).
