Androgens play a permissive role in the activation of calling activity, which is often positively correlated to androgen plasma levels and testes mass.

Additionally, calling effort is also correlated to corticosterone plasma levels hereinafter referred to as CORT , which is associated with the mobilization of energy substrates to sustain the high energy flux associated with this activity.

However, high CORT also has many immunosuppressive effects and might interfere with reproduction. Consequently, CORT might mediate a compromise between reproductive effort and immunocompetence in anurans. In the present study, we investigated the relationship between calling rate, immunocompetence, and CORT in Hypsiboas albopunctatus, a midsize anuran occurring in South America.

To understand these relationships, we conducted focal observations of calling behavior, followed by blood collection for CORT measurements and evaluation of some immune parameters. Our results showed that individuals with larger testes had higher calling rates, and those with higher calling rates showed lower cell-mediated immune response swelling response to phytohaemagglutinin , although these relationships were not mediated by CORT.

We conclude that calling activity shows a cost in terms of cellular immune response in H. Smart citations by scite.

B Chromosomes in the Tree Frog Hypsiboas albopunctatus (Anura: Hylidae)

Reverse hybridisation was also carried out in the investigation. The B probe exclusively painted the supernumerary, not hybridising any other chromosomes in H. This result might be an indication that differences exist between the repetitive sequences of A and B chromosomes of H. Although our results could suggest an interespecific origin of the B at first sight, further analysis on its repetitive sequences is still necessary. Nevertheless, the accumulation of repetitive sequences, detected in another species, even though closely related, remains an intriguing question. B chromosomes are extra elements present in the genome of diverse groups of plants and animals Jones and Rees ; Green ; Jones and Houben ; Camacho , ; Schmid et al.
