Reintroduction of captive-bred Chinese giant salamanders is a primary approach for restoring wild populations.Despite previous studies have investigated the habitat preferences of reintroduced Chinese giant salamanders,the intraspecific variation in their habitat selection has been neglected.In the present study,30 captive-bred Chinese giant salamanders belonging to 3 groups(i.e.,10 males,10 females,and 10 juveniles)were released into a montane stream to explore whether intraspecific variation in habitat selection occurred in this species using radiotelemetry.Our results indicated that linear home range and daily movement of males were significantly higher than those of females and juveniles.Male sedentariness was significantly lower than that of females and juveniles.No significant differences were detected between females and juveniles in these measures.Importantly,we found that males preferred microhabitats with low water conductivity and deep water depth.Females preferred microhabitats with high water conductivity,low dissolved oxygen and ammonium-nitrogen,and slow current velocity,while juveniles occupied microhabitats with low ammonium-nitrogen.In addition,males and juveniles exhibited higher niche breadth than females.Niche overlap was high between adults and juveniles but low between males and females.Our study revealed the presence of spatial segregation in reintroduced Chinese giant salamanders.Males,females,and juveniles exhibited variation in microhabitat selection.These results provide important information for use when planning strategies for conservation of Chinese giant salamanders.
