MORPHOLOGICAL INVESTIGATION OF TURKISH TREE FROGS, HYLA ARBOREA AND HYLA SAVIGNYI (ANURA: HYLIDAE)

Despite previous work on the phylogeny of Palearctic Hyla, several problems still exist regarding systematics of Hyla in Turkey. The systematics of tree frogs (Hyla orientalis and Hyla savignyi) in Turkey was studied using combined mitochondrial genes (12S ribosomal RNA and cytochrome b) and a nuclear gene (H3), and sampling a total of 102 individuals from 51 localities. We find that Hyla orientalis is represented by a single lineage, whereas Hyla savignyi was divided into two lineages by the mitochondrial genes, but not the nuclear gene. We also confirm that Hyla arborea schelkownikowi is a junior synonym of Hyla orientalis.

AbstractChorusing male anurans typically spend only a part of the breeding season calling although chorus tenure is often the best predictor of mating success. We determined the number of nights males attended a chorus (chorus tenure) and its influence on mating success in the European tree frog, Hyla arborea. The median chorus tenure was 7.5 nights out of a study season of 38 nights. Males that spent more than two nights in the chorus were present for an average of 47% of the nights between their first and last night in the chorus. Minimum daily temperature, ambient temperature at initiation of calling, and daily rainfall explained 37.8% of the variance in male attendance. Twenty-five males were calling on the night of peak activity, a fraction of the 44 males marked. This suggests that estimates of male population size based on peak activity, widely used by conservation biologists, are inaccurate. We suggest that, when mark-recapture methods cannot be used, male population size be calculated by using a regression model based on the peak number of calling males that can be further developed as more data accumulates.

Communication Modalities

The recent discovery of the use of visual cues for mate choice by nocturnal acoustic species raises the important, and to date unaddressed, question of how these signals affect the outcome of mate choice predicted by female preference for male calls. In order to address this question, we presented female Hyla arborea tree frogs with a series of choices between combinations of acoustic and visual cues of varying quality in nocturnal conditions. While females exhibited the expected preference for a combination of attractive values for visual and acoustic signals over combinations of unattractive values for both signals, when presented with conflicting acoustic and visual cues, they equally adopted one of two strategies, preferring either attractive calls or intense vocal sac coloration. This constitutes novel evidence that the outcome of mate choice, as predicted on the basis of male calling quality, can be drastically different when additional communication modalities—in this case vision—are taken into account. These results also highlight the possible existence of individual variation in female rules for cue prioritization. The implications of these results for the study of mate choice in nocturnal acoustic species are discussed.
