“…To explore this possibility, we broadcast and recorded calls that represent the most extreme range of variation (sympatric calls from Liberty Co., FL = site 3 and allopatric calls from Macon Co., AL = site 9) into four diverse habitat types: (1) pine savannah, (2) herbaceous wetland, (3) mixed pine forested wetland/bottomland, and (4) hardwood swamp. All four habitats are naturally inhabited by P. feriarum (Carr ; Neill ; Wright and Wright ; Smith and Smith ; Hudson ; Schwartz ; Gosner ; Fouquette ; E. Moriarty Lemmon, unpubl. data).…”

“…Although pulse number and pulse rate of P. feriarum vary between sympatry and allopatry, habitat preferences of the frogs also vary to some extent between geographic regions. Sympatric frogs tend to favor more specific habitats (cypress‐gum hardwood swamps along river floodplain corridors), particularly in deep sympatry, whereas allopatric frogs use a broader spectrum of habitats (Carr ; Neill ; Wright and Wright ; Smith and Smith ; Hudson ; Schwartz ; Gosner ; Fouquette ). The different habitats used by Pseudacris suggest that variation in advertisement calls could be due to selection for optimal transmission within habitats, which in turn could influence interactions between species in areas of sympatry, leading to the observed pattern of reproductive character displacement.…”

“…At the end of this embrace, the female strongly and repeatedly arches her back followed by the male immediately dismounting ( Fig. 1D ; Video S5 ), a behaviour known from other species too ( Gosner & Rossman, 1959 ). The female deposits eggs in a single bout immediately after the male dismounts ( Figs.…”

Anurans show the highest diversity in reproductive modes of all vertebrate taxa, with a variety of associated breeding behaviours. One striking feature of anuran reproduction is amplexus. During this process, in which the male clasps the female, both individuals’ cloacae are juxtaposed to ensure successful external fertilization. Several types of amplexus have evolved with the diversification of anurans, and secondary loss of amplexus has been reported in a few distantly related taxa. Within Nyctibatrachus, a genus endemic to the Western Ghats of India, normal axillary amplexus, a complete loss of amplexus, and intermediate forms of amplexus have all been suggested to occur, but many species remain unstudied. Here, we describe the reproductive behaviour of N. humayuni, including a new type of amplexus. The dorsal straddle, here defined as a loose form of contact in which the male sits on the dorsum of the female prior to oviposition but without clasping her, is previously unreported for anurans. When compared to known amplexus types, it most closely resembles the form of amplexus observed in Mantellinae. Furthermore, we prove that, opposed to the situation in most anurans, male semen release happens before egg deposition. We hypothesize that the male ejaculates on the female’s dorsum and that sperm subsequently runs from her back and hind legs before fertilizing the eggs. A second feature characterizing anuran breeding is the advertisement call, mostly produced solely by males. Despite recent descriptions of several new Nyctibatrachus species, few studies have explored their vocal repertoire. We describe both the male advertisement call and a female call for N. humayuni. The presence of a female call has not been reported within Nyctibatrachidae, and has been reported in less than 0.5% of anuran species. Altogether, our results highlight a striking diversity and several unique aspects of Nyctibatrachus breeding behaviour.

“…Males that attempt to mount an unreceptive female are quickly dissuaded by the female moving away, although this avoidance behaviour is not always successful [ 111 , 142 ]. Amplexus usually only occurs at night, but P. kalmi have been observed in amplexus during the day [ 103 ]. Observations of P. crucifer [ 82 ] and P. triseriata [ 103 ] suggests that ovulation precedes amplexus.…”

Life history traits and reproductive ecology of North American chorus frogs of the genus Pseudacris (Hylidae)

Amphibian biodiversity is declining globally, with over 40% of species being considered threatened to become extinct. Crucial to the success of conservation initiatives are a comprehensive understanding of life history and reproductive ecology of target species. Here we provide an overview of the Pseudacris genus, including breeding behaviour, reproduction, development, survival and longevity. We present an updated distribution map of the 18 species found throughout North America. We also summarize the conservation status at the national and subnational (state, provincial, and territorial) levels, in Canada, USA, and Mexico, to evaluate the relationship between life history traits and extinction risk. Results show a high degree of consistency in the life history traits of Pseudacris species considering their relative diversity and wide distribution in North America. However, data are lacking for several species, particularly in the Fat Frog and West Coast clades, causing some uncertainties and discrepancies in the literature. We also found that the most threatened populations of chorus frog were located in the east coast of the USA, potentially as a result of increased levels of anthropogenic disturbance. We suggest that the similarities in life history traits among chorus frog species provides an opportunity for collaboration and united efforts for the conservation of the genus.
