A comparative study of the mating call ofPelophylax ridibundusandPelophylax kurtmuelleri(Anura: Ranidae) from syntopic and allotopic populations

Alien fish, amphibian and reptile species in Romania and their invasive status: a review with new data

“…P. kurtmuelleri and P. ridibundus widely overlap in morphological and morphometric characteristics (Papežík et al 2021). The calls of P. kurtmuelleri are distinct, especially when in sympatry, from those of P. ridibundus -but whatever the song differences, even valid species do not segregate by song type and hybridize despite differences in calls (Lukanov et al 2015). Therefore, P. kurtmuelleri, even if often treated as part of P. ridibundus (Speybroeck et al 2016;Speybroeck et al 2020) is most probably a valid species, but its Romanian records may represent either misidentified (due to low marker specificity) P. ridibundus, or naturally occurring recombinants.…”

“…Common name(s): English: Balkan Water Frog (e.g., Kolenda et al 2017). This taxon is considered native to most of Greece, Albania, Northern Macedonia, Montenegro, southern Serbia, south-western Bulgaria (Lukanov et al 2015;Kolenda et al 2017;Vucić et al 2018), but widely introduced across Europe, probably mainly together with fish stocks (see, e.g., Kolenda et al 2017;Bisconti et al 2019). In Romania, a few specimens were determined through molecular protocols to pertain to Pelophylax kurtmuelleri (as opposed to the widespread Pelophylax ridibundus) (Marosi et al 2014;Vucić et al 2018).…”

First bioacoustic and morphological data for the presence of Pelophylax bedriagae in Bulgaria

“…Bioacoustic studies on frog populations from Greece, Bulgaria and Armenia have demonstrated the advertisement calls to be consistent with those from the type locality of the species -Atyrau, Kazakhstan [6], [14], [15], [1], [16], [17]. In Bulgaria, P. ridibundus is ubiquitous across the country, living in syntopy with Pelophylax kurtmuelleri (Gayda, 1940) to the South-West [18] and both the Pelophylax kl. esculentus (L., 1758) and Pelophylax lessonae (Camerano, 1882) along the Danube River [19].…”

Posição taxonômica de populações de Phyllomedusa do grupo de Phyllomedusa hypochondrialis Daudin (Anura, Hylidae, Phylomedusinae) com o reconhecimento de uma espécie nova

“…A comunicação através da emissão de sinais acústicos (vocalizações) é amplamente difundida entre os vertebrados, como por exemplo, os anuros, aves, morcegos, primatas, cetáceos (Duellman & Trueb, 1986). Os anuros são vocalmente ativos e a vocalização é um componente importante de seu comportamento reprodutivo (Lukanov et al, 2015). A diversidade do repertório vocal de Anura é muita extensa, e, baseando-se em seu contexto social, foi organizado em três categorias: reprodutivo, agressivo e defesa (Toledo et al, 2015).…”
