All eggs were incubated at 90% humidity and 29 \u00b0C for the first 45 days. Thereafter, the incubation temperature was either maintained at 29 \u00b0C and embryos were treated with 4-aminopyridine (4-AP) on days 46, 47, 48, and 49 (Group I, 29 \u00b0C 4-AP, n = 15); maintained at 29 \u00b0C (n = 14; Group II); or at 33 \u00b0C (n = 14, Group III). Embryonic movement was measured using an Egg Buddy\u00ae digital monitor on days 30, 35, 42, 49, 56, and 60, at which point embryos were euthanized and samples were collected for analysis. No differences were observed between groups with varying incubation temperatures. In contrast, embryonic motility was greater in embryos treated with 4-AP (P &lt; 0.001) on day 49, and this was associated with higher proportions of snout-vent and hand lengths. This study demonstrates for the first time that pharmacologically induced increases in embryo motility result in phenotypic changes to the proportion of elements during prenatal ontogeny, thereby effectively altering the adaptation of the species to specific environments.<\/jats:p>","DOI":"10.1590\/1519-6984.252845","type":"journal-article","created":{"date-parts":[[2021,12,20]],"date-time":"2021-12-20T12:40:33Z","timestamp":1640004033000},"source":"Crossref","is-referenced-by-count":1,"title":["Influence of incubation temperature and embryonic motility on the growth of members of Caiman yacare (Daudin, 1802)"],"prefix":"10.1590","volume":"84","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0909-2426","authenticated-orcid":false,"given":"L.
