“…Collections of PAM time‐series can also be considered as historical records of ecosystem acoustic dynamics worldwide, holding a special value for areas undergoing intense changes in land use and/or climate (Krause and Farina ; Dena et al. ; Sugai and Llusia ). Still, these datasets require detailed recording protocols to promote repeatable surveys and research synthesis (Cassey and Blackburn ; Gibb et al.…”

Passive acoustic monitoring (PAM) is increasingly popular in ecological research and conservation programs, with high-volume and long-term data collection provided by automatized acoustic sensors offering unprecedented opportunities for faunal and ecosystem surveys. Practitioners and newcomers interested in PAM can easily find technical specifications for acoustic sensors and microphones, but guidelines on how to plan survey designs are largely scattered over the literature. Here, we (i) review spatial and temporal sampling designs used in passive acoustic monitoring, (ii) provide a synthesis of the crucial aspects of PAM survey design and (iii) propose a workflow to optimize recording autonomy and recording schedules. From 1992 to 2018, most of the 460 studies applying PAM in terrestrial environments have used a single recorder per site, covered broad spatial scales and rotated recorders between sites to optimize sampling effort. Continuous recording of specific diel periods was the main recording procedure used. When recording schedules were applied, a larger number of recordings per hour was generally associated with a smaller recording length. For PAM survey design, we proposed to (i) estimate memory/battery autonomy and associated costs, (ii) assess signal detectability to optimize recording schedules in order to recover maximum biological information and (iii) evaluate cost-benefit scenarios between sampling effort and budget to address potential biases from a given PAM survey design. Establishing standards for PAM data collection will improve the quality of inferences over the broad scope of PAM research and promote essential standardization for cross-scale research to understand long-term biodiversity trends in a changing world.

Evolution of treefrogs' calls in tropical islands might be under directional selection

Animals that present migration restrictions are especially interesting to study isolation effects in the context of island biogeography theory. Among these effects, behavioral traits are one of the least studied subjects. The treefrog Boana albomarginata presents gigantism in some Atlantic islands and, therefore, examining its advertisement calls may be an opportunity to test the Island Rule with a behavioral trait. Hence, we compared calls, body and tympanum sizes of populations of this species in Brazilian islands and mainland sites. We tested if call frequencies of island individuals differed from mainland ones, also considering the influence of body size and its relationship with tympanum diameter. One of the island population had larger body size and lower call frequencies than any other populations. We suggest that to be a result of directional selection. We also observed lack of correlation between body size and advertisement call frequencies in some populations, implying that males and females cannot use calls as a proxy of the calling male's size, which may indicate a rare case of relaxed selection. Therefore, this is the first evidence of relaxed selection in animal communication, as a consequence of recent insularity.

“…Los anfibios tienen una alta sensibilidad a los cambios antropogénicos (Vallan, 2002;Blaustein et al, 2011), esta cualidad los hace buenos indicadores de cambios ambientales como deforestación, fragmentación del hábitat y enfermedades emergentes, entre otros (Priambodo et al, 2019). El registro, almacenamiento y curación de sonidos de anfibios es esencial, pues dichas grabaciones pueden ser útiles para estudios futuros de comunicación, comportamiento, historia natural, monitoreos de poblaciones, taxonomía, evolución y conservación de especies (Dena et al, 2019), entre otros (Tabla 1). Dependiendo del tipo de grabación que se realice (directa/ambiental) se obtiene información diferente.…”

“…Por ejemplo, si es directa puede aislarse el canto de un solo el individuo, y si es ambiental se graban todos los cantos y sonidos ambientales que alcance a detectar la grabadora. Por este motivo, las grabaciones ambientales también pueden contener información sobre la población y las condiciones ambientales de ese momento ya que muchas veces se obtienen durante coros o bien se puede percibir el ruido de fondo (Dena et al, 2019).…”

La Colección de Sonidos de anuros del Museo de Zoología “Alfonso L. Herrera” de la Facultad de Ciencias cuenta con 15,500 grabaciones donde se han identificado 27 especies, 18 géneros y 10 familias. La mayoría pertenecientes al estado de Chiapas. Las familias con mayor representación en la biblioteca son Hylidae (10 especies) y Craugastoridae (tres especies). La colección resguarda los cantos de anuncio de cinco especies en alguna categoría de riesgo según la Norma Oficial Mexicana-059. La localidad mejor representada hasta ahora es Nahá, Chiapas, sin embargo, se espera que el número de grabaciones y zonas muestreadas aumente con la contribución de la comunidad científica y público en general. Destacamos la importancia de esta colección científica por ser la primera en su tipo en México.
