В статье представлены результаты исследования периодичности и длительности линек у гребенчатого тритона (Triturus cristatus (Laurenti, 1768)) в искусственных условиях. Наблюдения проводились в течение 259 суток (с 11 февраля по 30 сентября 2022 г.) на 11 парах взрослых особей, содержавшихся в лабораторных условиях после искусственной зимовки. Установлено, что наибольшая интенсивность линек наблюдается в период размножения (апрель-май), причем самки линяют статистически значимо чаще и дольше, чем самцы. Вне репродуктивного сезона частота и продолжительность линек снижаются. Полученные данные позволяют предположить, что изменения в ритме линьки связаны с физиологической необходимостью поддержания эффективности кожного дыхания в водной фазе жизни, а также с гормональными и энергетическими затратами, связанными с репродукцией. Результаты исследований расширяют представления о физиологии кожных покровов хвостатых амфибий и их адаптации к сезонным изменениям жизненного цикла.

This article presents the results of a study on the periodicity and duration of molting in the crested newt (Triturus cristatus (Laurenti, 1768)) under artificial conditions. Observations were conducted over 259 days (from February 11 to September 30, 2022) on 11 pairs of adult individuals maintained under laboratory conditions following artificial wintering. It was established that the highest molting intensity occurs during the breeding season (April–May), with females molting statistically significantly more frequently and for longer periods than males. Outside the reproductive season, both molting frequency and duration decrease. The obtained data suggest that changes in the molting rhythm are associated with the physiological necessity of maintaining efficient cutaneous respiration during the aquatic phase of life, as well as with hormonal and energetic expenditures related to reproduction. These results expand our understanding of the skin physiology of caudate amphibians and their adaptation to seasonal changes in their life cycle
