FIGURE 18 in The use of bioacoustics in anuran taxonomy: theory, terminology, methods and recommendations for best practice
FIGURE 18. Interpretation of advertisement call differences: (A) Spectrograms and oscillograms of calls of two allopatric frog species without any significant differences (evidence for species-level divergence by molecular genetics and tadpole morphology; Vences et al. 2010a). (B) Moderate structural call differences of two allopatric populations currently assigned to the same species. The calls of Blommersia wittei from Sambava and Andrakata are composed of clicking notes of a metallic sound, whereas at Nosy Be, Benavony, and Montagne d'Ambre, notes contain pulses and calls exhibit less distinct inter-note intervals. Spectrograms produced with CoolEdit Pro at Hanning window function, 256 bands resolution.
FIGURE 16 in The use of bioacoustics in anuran taxonomy: theory, terminology, methods and recommendations for best practice
FIGURE 16. Spectrograms illustrating qualitative call differences between closely related species (all mantellid frogs from Madagascar). All spectrograms show only a section of a longer series of notes. Gephyromantis eiselti and G. thelenae form a clade together with a third species (Kaffenberger et al. 2011). While G. eiselti emits series of tonal notes, G. thelenae emits much slower series of much longer pulsed notes at similar temperatures. Boophis majori and B. narinsi are sister species (Wollenberg et al. 2011) and differ extremely in note duration and note repetition rate (short clicks vs. long pulsatile sounds). In both cases, the species in each pair occur in syntopy and are extremely similar to each other in adult morphology. Despite distinct qualitative call differences, genetic divergences between each of the two species pairs are remarkably low (p-distances 2.2–3.3% in a fragment of the mitochondrial 16S rRNA gene; Wollenberg & Harvey 2010; Vences et al. 2012a). In such extreme cases of bioacoustical divergence, and if the presence of different call types or recording artifacts can be excluded, bioacoustical data provide conclusive evidence for species level divergence. Recordings from Vences et al. (2006, 2012a); spectrograms made with the R package Seewave (Sueur et al. 2008a) at Hanning windowing function, 512 bands resolution.
FIGURE 9 in The use of bioacoustics in anuran taxonomy: theory, terminology, methods and recommendations for best practice
FIGURE 9. Example illustrating the need to consider homology aspects in terminoloy of anuran vocalizations. The calls shown are from four related species of mantellid frogs in the nominal subgenus of the genus Gephyromantis. The four species emit vocalizations consisting of a series of sound units (each corresponding to one expiration), with a defined number of units per series. All spectrograms are to scale; for G. boulengeri, an entire series is shown whereas the remaining spectrograms show parts of a series. In a note-centered terminology, one entire series would be a call, and each sound unit a note. In a call-centered terminology, in G. boulengeri, a series might be defined as one call (because no intervals of full silence occur between sound units), while in G. enki, each sound unit would be a call (separated by wide intervals of silence from the next call) and the series would be a call series. Either definition might be appropriate when looking at a single species, but in a comparative taxonomic study, it is of utmost importance to compare homologous bioacoustical entities and to apply the same name to them; hence, in a call centered approach, also the vocalization of G. boulengeri would need to be dubbed a call series. Spectrograms made with the R package Seewave (Sueur et al. 2008a) at Hanning windowing function, 512 bands resolution. Note that we here refer to homology from the perspective of sound production (one unit corresponding to one expiration) and not from the perspective of signal content of the respective sound unit.
FIGURE 12 in The use of bioacoustics in anuran taxonomy: theory, terminology, methods and recommendations for best practice
FIGURE 12. Nightly variation of dominant frequency (A) and call duration (B) in one individual of Leptodactylus syphax. One nocturnal activity phase of ca. 2 hrs of calling (n = 8,106 calls; 29.9 to 31.8 °C). Recording was obtained on 17 November 2014 at the Research Station 'Chiquitos', Bolivia, with a Song Meter SM2 (Wildlife Acoustics; sampling frequency 22,050 Hz; 16- bit resolution), and afterwards analyzed with software Raven Pro, version 1.4 (Bioacoustics Research Program 2011) using implemented amplitude detectors; statistics were done with R; only calls with high amplitude were considered (i.e., less intense 'introductory calls' of a series were excluded). Red lines show smoothed data (Local Polynomial Regression Fitting with span=0.05; M. Jansen & A. Masurowa, unpubl. data).
FIGURE 23 in The use of bioacoustics in anuran taxonomy: theory, terminology, methods and recommendations for best practice
FIGURE 23. Spectrograms and oscillograms of calls of the same individual of Bombina bombina recorded at different saturations of the recording levels and different recording distances (Tascam DR-05 digital recorder and a Sennheiser K6/ ME66 microphone; water temperature 22.1 °C; 24 May 2015 at Schorfheide-Chorin Reserve, Germany). Calls were successively recorded from the same individual within a short time period of ca. 30 minutes and each spectrogram thus shows a different call. The upper left spectrogram is from a recording with recording levels in the field deliberately set on oversaturation. The other three spectrograms were analyzed with equalized levels. Note that the number of harmonics is highest in the oversaturated recording, but also depends on recording distance, with the highest-frequency harmonics disappearing with increasing distance. Sounds of birds and insects are visible on the recordings that were not filtered to allow objective comparison. All spectrograms made with the R package Seewave (Sueur et al. 2008a), with settings: Hanning window function, 1024 bands resolution, overlap = 90%.
FIGURE 14 in The use of bioacoustics in anuran taxonomy: theory, terminology, methods and recommendations for best practice
FIGURE 14. Variation of two call traits within the Madagascar-Comoroan anuran family Mantellidae. (A) Correlation of dominant frequency and maximum male snout-vent length in 155 mantellid species. (B) Variation of note duration (mean, minimum and maximum values) among 171 species of mantellids, ordered by mean note duration (5–20 measurements per species). On Y-axis values are arranged along a logarithmic scale for graphical reasons (but scale shows original values in milliseconds, not log-transformed values). Notes defined following a note-centered scheme (cf. Fig. 7).

Data from: The effect of neighborhood size on effective population size in theory and in practice
The distinction between the effective size of a population (Ne) and the effective size of its neighborhoods (Nn) has sometimes become blurred. Ne reflects the effect of random sampling on the genetic composition of a population of size N, whereas Nn is a measure of within-population spatial genetic structure and depends strongly on the dispersal characteristics of a species. Although Nn is independent of Ne, the reverse is not true. Using simulations of a population of annual plants, it was found that the effect of Nn on Ne was well approximated by Ne=N/(1−FIS), where FIS (determined by Nn) was evaluated population wide. Nn only had a notable influence of increasing Ne as it became smaller (less than or equal to16). In contrast, the effect of Nn on genetic estimates of Ne was substantial. Using the temporal method (a standard two-sample approach) based on 1000 single-nucleotide polymorphisms (SNPs), and varying sampling method, sample size (2–25% of N) and interval between samples (T=1–32 generations), estimates of Ne ranged from infinity to <0.1% of the true value (defined as Ne based on 100% sampling). Estimates were never accurate unless Nn and T were large. Three sampling techniques were tested: same-site resampling, different-site resampling and random sampling. Random sampling was the least biased method. Extremely low estimates often resulted when different-site resampling was used, especially when the population was large and the sample fraction was small, raising the possibility that this estimation bias could be a factor determining some very low Ne/N that have been published.
