摘      要：Animals constantly need to evaluate available external and internal information to make appropriate ***,assessing,and acting on relevant cues in contexts such as mate choice,intra-sexual competition,and parental care is particularly important for optimizing individual reproductive *** factors can infuence decision-making,such as external environmental cues and the animal’s own internal state,yet,we have limited knowledge on how animals integrate available ***,we used an entire island population(57 males,53 females,and 1,109 tadpoles)of the neotropical brilliant-thighed poison frog Allobates femoralis to investigate how 2 factors(olfactory cues and personality traits)infuence the ability of males to fnd and use new resources for tadpole *** experimentally manipulated the location of tadpole deposition sites and their associated olfactory cues,and repeatedly measured exploration and boldness in adult *** further reconstructed tadpole deposition choices via inferred parent–offspring relationships of adult frogs and tadpoles deposited in our experimental pools using molecular parentage *** found that the discovery and use of new rearing sites were heavily infuenced by olfactory cues;however,we did not fnd an effect of the measured behavioral traits on resource discovery and *** conclude that in highly dynamic environments such as tropical rainforests,reliable external cues likely take priority over personality traits,helping individuals to discover and make use of reproductive resources.
