The genus Gastrotheca Fitzinger, 1843 currently harbors 75 species (Frost 2020). These marsupial frogs have a broad latitudinal distribution range in Central and South America, from Costa Rica southward to Argentina (Duellman 2015). The advertisement call features as the pulse structure, call duration, and repetition pulse rate are used by researchers to recognize the species of Gastrotheca (Duellman 2015). The availability of call descriptions is also crucial for recognizing these species with secretive life habits and implementing long-term passive acoustic monitoring programs (Vaira et al. 2011; Akmentins et al. 2014).

The advertisement call of two species of the Rhinella granulosa group (Anura: Bufonidae). The group of Rhinella granulosa presently harbors 14 species distributed in Central and South America. The advertisement calls of 12 species have been described. Herein, we provide data on the calls of R. granulosa and R. merianae recorded in populations far from locations of previous call descriptions, and we discuss possible causes of differences found. We used recordings of R. granulosa from the interior of Bahia State and recordings of R. merianae from Roraima. For both, calls consist of a long-lasting trill of four-pulsed notes. Rhinella granulosa calls last 3.7–9.6 s, have 121–283 notes, each lasting 19–25 ms released at a rate of 29.2–34.7/s, and with dominant frequency peaking between 2472–2809 Hz. Rhinella merianae calls last 4.0–7.1, have 153–217 notes, each lasting 17–20 ms, released at a rate of 37.7–39.5/s, and with dominant frequency peaking between 2959–3189 Hz. Both species are distinguished from most other species of the R. granulosa species group by the combination of pulse number and dominant frequency. Our data on R. granulosa differed (p < 0.05) in call duration and/or in dominant frequency from specimens from Natal (Rio Grande do Norte state) and Cabaceiras (Paraíba state). Our data on R. merianae appear to differ in dominant frequency from the only call (a single male) known from the Amazon River bank. The differences we found between our data and published call data suggest that further study of calls of additional populations of these species is warranted.

Passive Acoustic

Cook Inlet, Alaska, is home to an endangered and declining population of 279 belugas (Delphinapterus leucas). Recovery efforts highlight a paucity of basic ecological knowledge, impeding the correct assessment of threats and the development of recovery actions. In particular, information on diet and foraging habitat is very limited for this population. Passive acoustic monitoring has proven to be an efficient approach to monitor beluga distribution and seasonal occurrence. Identifying acoustic foraging behavior could help address the current gap in information on diet and foraging habitat. To address this conservation challenge, eight belugas from a comparative, healthy population in Bristol Bay, Alaska, were instrumented with a multi-sensor tag (DTAG), a satellite tag, and a stomach temperature transmitter in August 2014 and May 2016. DTAG deployments provided 129.6 hours of data including foraging and social behavioral states. A total of 68 echolocation click trains ending in terminal buzzes were identified during successful prey chasing and capture, as well as during social interactions. Of these, 37 click trains were successfully processed to measure inter-click intervals (ICI) and ICI trend in their buzzing section. Terminal buzzes with short ICI (minimum ICI <8.98 ms) and consistently decreasing ICI trend (ICI increment range <1.49 ms) were exclusively associated with feeding behavior. This dual metric was applied to acoustic data from one acoustic mooring within the Cook Inlet beluga critical habitat as an example of the application of detecting feeding in long-term passive acoustic monitoring data. This approach allowed description of the relationship between beluga presence, feeding occurrence, and the timing of spawning runs by different species of anadromous fish. Results reflected a clear preference for the Susitna River delta during eulachon (Thaleichthys pacificus), Chinook (Oncorhynchus tshawytscha), pink (Oncorhynchus gorbuscha), and coho (Oncorhynchus kisutch) salmon spawning run periods, with increased feeding occurrence at the peak of the Chinook and pink salmon runs.
