Morphometric Relationships, Growth and Condition Factors of Critically Endangered Chinese Pangolin (<i>Manis pentadactyla</i>)

Abstract

Morphometric relationships and condition factors are crucial to quickly understanding the fitness and well-being of animals. Total length (cm) and bodyweight (g) of 282 (male = 167 and female = 115) pangolins were accounted for in this study which was received and rehabilitated in Pingtung Rescued Center, Pingtung and Endemic Species Research Institute, Nantou, Taiwan. The allometric equation; W = aLb was used to estimate the length-weight relationships where R2 = 0.70, a = 0.61, and b = 1.98. The ratio of total body length and tail length was between 1.1 and 2.7. Pangolins exhibited negative allometric growth (b R) was 1.04, indicating a state of good health for rescued individuals. However, Fulton condition factor (KF) and KR fluctuated in different months but was significantly heavier during the wet seasons. This study recommended to release healthy animals with KF of 0.8 or higher back into the wild in order to increase their survival rate. The study, thus will be helpful to promote standardized guidelines for conducting physical measurements and understanding health status. Additionally, it will support the recovery of this threatened species by husbandry and diet management in ex-situ and in-situ conservation.
