SABRINA HAISYA. A Study of Reproductive Period of Tigers (Panthera tigris)
Ex Situ. Supervised by LIGAYA ITA TUMBELAKA.
Tigers (Panthera
tigris) are the largest cat in the world. However, the number of tigers in
the wild started declining since the earlier of twentieth century. Therefore,
the world conservation agencies declared the tiger status as endangered species.
Some of the tigers status are even declared as critically endangered and extinct
in the wild. Many local conservation institutions have been active to increase
the tiger numbers. Nevertheless, there were not sufficient studies in tiger reproduction
to optimize the conservation efforts. This study aims to analyze the reproductive
period of tigress (female tiger) and its correlation with geography, life span,
frequency of giving birth and age at the first reproduction activity. Sixty nine
(69) Amur, 60 Sumatran, 30 Bengal, and 12 South China tigers were selected as
samples. Samples were statistically analyzed using Spearman, Kruskal Wallis, oneway
ANOVA, and descriptive test. The result showed that the reproductive period has
not showed siginficant differences within subspecieses and geography. Although,
there were significant correlation (p<0 .01="" a="" activity.="" age="" aims="" an="" analysis="" and="" are="" at="" be="" between="" birth.="" birth="" breeding="" by="" captive="" conservation="" earlier="" every="" experience="" factor="" first="" for="" frequency="" gave="" given="" giving="" global="" greater="" has="" important="" improvement="" in="" institution.="" institution="" is="" knowledge="" lead="" life="" longer.="" longer="" management="" needed="" noted="" o:p="" of="" opportunity="" period="" population="" possibility="" raising="" reach="" reproduction="" reproductive="" should="" showed="" span="" that="" the="" those="" thus="" tiger="" tigress="" to="" world.="" would="">
