temporal selectivity of evoked vocal responses of batrachyla antartandica (amphibia: leptodactylidae)	the advertisement call of the leptodactylid frog batrachyla antartandica from southern chile consists of a train of brief percussive tone pulses whose energy is centred at about 2 khz. to gain an understanding of the temporal features that are essential for call recognition, playback experiments were conducted with 11 males. subjects were presented with a synthetic imitation of this signal and variants for which different temporal call parameters were modified systematically. the number of pulse ...	1997	9344437
temporal selectivity by single neurons in the torus semicircularis of batrachyla antartandica (amphibia: leptodactylidae).	we investigated the response selectivities of single auditory neurons in the torus semicircularis of batrachyla antartandica (a leptodactylid from southern chile) to synthetic stimuli having diverse temporal structures. the advertisement call for this species is characterized by a long sequence of brief sound pulses having a dominant frequency of about 2000 hz. we constructed five different series of synthetic stimuli in which the following acoustic parameters were systematically modified, one a ...	2001	11866188
extended amplification of acoustic signals by amphibian burrows.	animals relying on acoustic signals for communication must cope with the constraints imposed by the environment for sound propagation. a resource to improve signal broadcast is the use of structures that favor the emission or the reception of sounds. we conducted playback experiments to assess the effect of the burrows occupied by the frogs eupsophus emiliopugini and e. calcaratus on the amplitude of outgoing vocalizations. in addition, we evaluated the influence of these cavities on the recepti ...	2016	27209276
genomic epidemiology of the emerging pathogen batrachochytrium dendrobatidis from native and invasive amphibian species in chile.	emerging fungal diseases represent a threat to food security, animal and human health worldwide. amphibian chytridiomycosis, caused by the fungus batrachochytrium dendrobatidis (bd), has been associated with catastrophic and well-documented amphibian population declines and extinctions. for the first time, bd was cultured from native and non-native wild amphibians in chile. phylogenomic analyses revealed that chilean isolates avs2, avs4 and avs7 group within the global panzootic lineage of bd (b ...	2017	29205924
