- Abstract
Selective poaching of males for ivory has led to female-biased adult sex ratios in Asian elephants. Therefore, sex ratio monitoring is common, but is undertaken without examining short-term variability. We examined monthly adult sex ratios during the dry season in Nagarahole and Bandipur National Parks, southern India, using visual capture-recapture and counts of identified males and females. We found monthly differences in sex ratios because males and females used the area differently. Using sightings irrespective of identity gave less female-biased sex ratios during peak summer when censuses are usually carried out. We discuss the implications of our results for management.
