บทคัดย่อ :
The arboreal frog, Chiromantis hansenae (Family: Rhacophoridae), is one of
only a handful of South-East Asian amphibian species reported with
parental care. We present the first systematic observational and experi-
mental study confirming offspring benefits as a result of this care, which
has a number of unusual life-history characteristics. Eggs are unusually
small, breeding takes place in large pools, and females attend the eggs.
Field observations and an adult removal experiment demonstrated a criti-
cal contribution of egg attendance to offspring survivorship. Harsh envi-
ronmental conditions for offspring appeared to be the prime mover of
parental care in this species, with desiccation as the main source of mor-
tality when attending adults are absent. Results confirm females to be the
caregivers, making C. hansenae a rare case of maternal egg attendance in a
non-directly developing anuran.
