“…Faster call rates are potentially indicative of male condition [34,35] and his ability to confer fitness benefits to females or their offspring. Indeed, allopatric females obtain goodcondition mates that provide both enhanced fertilization success and better-quality offspring, whereas sympatric females do not [23,24].…”

Reproductive character displacement is the adaptive evolution of traits that minimize deleterious reproductive interactions between species. When arising from selection to avoid hybridization, this process is referred to as reinforcement. Reproductive character displacement generates divergence not only between interacting species, but also between conspecific populations that are sympatric with heterospecifics versus those that are allopatric. Consequently, such conspecific populations can become reproductively isolated. We compared female mate preferences in, and evaluated gene flow between, neighbouring populations of spadefoot toads that did and did not occur with heterospecifics (mixed-and pure-species populations, respectively). We found that in mixed-species populations females significantly preferred conspecifics. Such females also tended to prefer a conspecific call character that was dissimilar from heterospecifics. By contrast, females from pure-species populations did not discriminate conspecific from heterospecific calls. They also preferred a more exaggerated conspecific call character that resembles heterospecific males. Moreover, gene flow was significantly reduced between mixed-and pure-species population types. Thus, character displacement (and, more specifically, reinforcement) may initiate reproductive isolation between conspecific populations that differ in interactions with heterospecifics.

“…Similarly, males of Dendropsophus phlebodes (Stejneger, 1906) and Dendropsophus microcephalus (Cope, 1886) also increased the We observed that 10 and six males of H. goianus emitted advertisement and aggressive calls during all treatment periods of the Sequence A playback experiment, respectively (Table rate of their aggressive call in response to conspecific calls (WELLS 1988). According to TAIGEN & WELLS (1985), the calling activity of anurans is one of their most energetically expensive activities; several studies have demonstrated that males emitting more calls per minute are more attractive to females (e.g., BOSCH & MÁRQUEZ 2005, POOLE & MURPHY 2007. In this context, males that are able to maintain high call rates have higher energetic costs and therefore are in better physical shape (POOLE & MURPHY 2007) to obtain the female's preference.…”

“…It is also necessary to take into consideration that exposure to environmental and social stressors can suppress immune function and increase susceptibility to disease (Klein, 2000b). Several studies in Amphibia illustrate that courtship displays are costly from the metabolism point of view, being able to increase male susceptibility to infection (Taigen & Wells, 1985;Pfennig & Tinsley, 2002). This factor could have contributed to increase the parasitic load of R. perezi males.…”

Summary :The helminth communities of two populations of green frogs from both shores of the Alborán Sea (Western Mediterranean) were studied. Of the 79 frogs examined for helminths, 39 individuals of the species Rana saharica were collected from Bab-Taza (Morocco), and 40 of the species Rana perezi were collected from the Natural Park of the Sierra de Grazalema (Spain). Although the species richness of helminths was identical in the two sampled areas, the differences observed in the structure of the helminth infracommunities were quite important. Statistically, significant differences were found between the species richness and the diversity of the infracommunities of R. perezi female population and the other three studied statistical populations. The helminth component communities of these two green frogs can be considered as depauperate, although their infracommunities present interactive features.
