“…Characteristics of advertisement calls for species of Cycloramphus with formally described calls. Modified from Lima et al (2010) and including C. bandeirensis. The call type follows Heyer (1983a).…”

“…The presence and development of the iris meniscus, the skin flap, spiracle, and reduced caudal fin are most obvious in tadpoles of Stages 33-38. Unfortunately, there is little information on the ontogeny and phenotypic variation in descriptions of tadpoles of Cycloramphus (e.g., Lima et al 2010, Nunesde-Almeida et al 2016.…”

“…The advertisement calls of seven species of Cycloramphus were described after 1983; those of C. bolitoglossus (Lingnau et al 2008), C. eleutherodactylus, C. faustoi (Brasileiro et al 2007), C. juimirim (Haddad and Sazima 1989), and C. valae (Heyer 1983b) are long, Type-B calls. Although the advertisement call of C. lutzorum was described as Type B (Lima et al 2010), it actually is Type A; the authors used a scale of milliseconds, giving the impression of a long note, but the note length is 0.05-0.06 s, as observed in C. boraceiensis, for example (Table 3). There is no clear association of types of advertisement calls with taxonomy, habitat, or phenotypic characters; thus far, stream-dwelling species of Cycloramphus have simple long, short, or complex calls, whereas all the forestlitter Cycloramphus have long simple calls.…”

Rediscovering Cycloramphus bandeirensis (Anura: Cycloramphidae): natural history and breeding biology of a vulnerable species with a variant reproductive mode. We present here data on the breeding biology of Cycloramphus bandeirensis, including descriptions of the advertisement call and tadpole. Males call from beneath rocks in open grasslands above approximately 2,450 m a.s.l. at the Parque Nacional do Caparaó, southeastern Brazil. Breeding occurs from late October–December, when mist and clouds frequently cover the area. The advertisement call consists of a frst note, followed by two or three shorter ones. The spawn is hidden under rocks from which the males call, and the tadpoles are exotrophic and semiterrestrial. This report of a semiterrestrial tadpole that develops in seclusion in a terrestrial habitat is a variant of Reproductive Mode 19. We compared the ontogeny of the semiterrestrial tadpole of C. bandeirensis to that of generalized tadpoles, and a new function is ascribed to the skin fap that is present in larvae of Cycloramphus. It is suggested that C. bandeirensis be transferred to Vulnerable category (VU, d2) of IUCN; the species has a small geographic range (< 20 km2 ), specialized environmental requirements, is vulnerable, has phylogenetic affnities to species that consistently have undergone local population crashes in southeastern Brazil, and is subject to plausible potential threats in its range (e.g., fres and climate change).

“…Saxicolous environments are not only more exposed but offer limited suitable egg‐laying sites in splash zones in the vicinity of waterfalls (Haddad and Sazima ; Giaretta and Cardoso ; Lima et al. ; Silva and Ouvernay ). This resource limitation leads to intense competition for egg‐laying sites and presumably favors larger males that have an advantage in antagonistic interactions.…”

“…Saxicolous Cycloramphus have eggs, larvae, and mating behaviors that are exposed to conspecific male competitors (Giaretta and Cardoso 1995;Giaretta and Facure 2003;Verdade 2005;Maia-Carneiro et al 2012), a condition that was likely shared by their common ancestor. Saxicolous environments are not only more exposed but offer limited suitable egg-laying sites in splash zones in the vicinity of waterfalls (Haddad and Sazima 1989;Giaretta and Cardoso 1995;Lima et al 2010;Silva and Ouvernay 2012).

Terrestrial breeding is a derived condition in frogs, with multiple transitions from an aquatic ancestor. Shifts in reproductive mode often involve changes in habitat use, and these are typically associated with diversification in body plans, with repeated transitions imposing similar selective pressures. We examine the diversification of reproductive modes, male and female body sizes, and sexual size dimorphism (SSD) in the Neotropical frog genera Cycloramphus and Zachaenus, both endemic to the Atlantic rainforest of Brazil. Species in this clade either breed in rocky streams (saxicolous) or in terrestrial environments, allowing us to investigate reproductive habitat shifts. We constructed a multilocus molecular phylogeny and inferred evolutionary histories of reproductive habitats, body sizes, and SSD. The common ancestor was small, saxicolous, and had low SSD. Terrestrial breeding evolved independently three times and we found a significant association between reproductive habitat and SSD, with shifts to terrestrial breeding evolving in correlation with decreases in male body size, but not female body size. Terrestrial breeding increases the availability of breeding sites and results in concealment of amplexus, egg‐laying, and parental care, therefore reducing male‐male competition at all stages of reproduction. We conclude that correlated evolution of terrestrial reproduction and small males is due to release from intense male‐male competition that is typical of exposed saxicolous breeding.
