“…Foam nests in anurans are produced by the whipping of oviductal secretions by one or both parents. Although some progress in the biochemical characterization of these secretions (Cooper et al., 2005; McMahon et al., 2006; Hissa et al., 2008; Fleming et al., 2009; Mackenzie et al., 2009) and in the anatomy and histochemistry of the secreting section of the oviduct (Coe, 1974; Kabisch et al., 1998; Alcaide et al., 2009; Furness et al., 2010) is slowly starting to take place, most studies have focused on the mechanics of foam production by the amplectic couple (Tyler and Davies, 1979; Hödl, 1986, 1990, 1992; Schlüter, 1990; Williams and Tyler, 1994; Altig and McDiarmid, 2007; Bastos et al., 2010; Dalgetty and Kennedy, 2010).…”

“…The mechanics of inguinal amplexus seem incompatible with foam beating by the male, whose rear limbs lay quite distant from the cloaca of the female. In fact, in limnodynastids where both foam‐nesting and inguinal amplexus occur, the foam is beaten by the female with the help of expanded flanges on her fingers (Martin, 1967; Tyler and Davies, 1979). Our results suggest that in Pleurodema the inguinal amplexus evolved from axilary amplexus after the transformations leading to spawns without foam nests (Fig.…”

A phylogenetic analysis of Pleurodema (Anura: Leptodactylidae: Leiuperinae) based on mitochondrial and nuclear gene sequences, with comments on the evolution of anuran foam nests

Species of the genus Pleurodema are relatively small, plump frogs that mostly occur in strong‐seasonal and dry environments. The genus currently comprises 14 species distributed from Panama to southern Patagonia. Here we present a phylogenetic analysis of Pleurodema, including all described species and several outgroups. Our goals include testing its monophyly and the monophyly of the species groups that were historically proposed, and studying the evolution of some character systems, particularly macroglands and egg‐clutch structure; this last point also provided the chance for a discussion of foam nest evolution in anurans. Our dataset includes portions of the mitochondrial genes cytochromeb, 12S, 16S, and the intervening tRNAVal; the nuclear gene sequences include portions of rhodopsin exon 1 and seven in absentia homolog I. Our results support a clade composed of Pleurodema and including the monotypic SomuncuriaLynch, 1978 nested within it. The latter genus is therefore considered a junior synonym of Pleurodema and its sole species is added to this genus. Furthermore, our results indicate the non‐monophyly of several species groups proposed previously. We recognize four clades in Pleurodema: the P. bibroni clade (P. bibroni, P. cordobae and P. kriegi), the P. thaul clade (P. bufoninum, P. marmoratum, P. somuncurensis and P. thaul), the P. brachyops clade (P. alium, P. borellii, P. brachyops, P. cinereum, P. diplolister and P. tucumanum) and the P. nebulosum clade (P. guayapae and P. nebulosum). Our results further indicate the need for a taxonomic reassessment of P. borellii and P. cinereum (as did previous studies), P. guayapae and P. nebulosum, and the three species in the P. bibroni clade. Pleurodema shows a striking pattern of variation in presence/absence of lumbar glands. Our results indicate multiple losses or independent gains of this character associated with defensive displays. The reproductive modes of Pleurodema include four different egg‐clutch structures. The optimization of these indicates that there are at least two independent transformations from the plesiomorphic mode of foam nests to egg‐clutch structures involving gelatinous masses of different sorts (ovoid plates, masses, or strings). We hypothesize that these independent transformations could involve changes at the behavioural (the loss of foam beating behaviour by the parent) and/or structural level (transformations involving the pars convoluta dilata, the section of the oviduct where the foam‐making substance is secreted). Finally, our study of foam nest evolution in Pleurodema is extended to the other groups of anurans where foam‐nesting occurs, on the basis of available data and recent phylogenetic hypotheses. In the different hyloid groups where it occurs, foam‐nesting evolved from clutches laid in water. However, in all ranoids in which foam‐nesting occurs, it evolved from terrestrial clutches, with eggs laid hanging in vegetation, or, if the clutches are laid on a restricted volume of water, involving endotrophic develop...

“…Such nests are produced by certain hylids (Haddad et al, 1990), hyperoliids (Amiet, 1974), leptodactylids (e.g., Hö dl, 1990;Schlü ter, 1990;Shepard and Caldwell, 2005), limnodynastids (e.g., Littlejohn, 1963;Tyler and Davies, 1979), microhylids (e.g., Glaw and Vences, 1992;Haddad and Hö dl, 1997), and rhacophorids (e.g., Coe, 1974;Fukuyama, 1991;Liu, 1950); and see Duellman and Trueb (1986). Suggested functions for froth nests include: escape from the aquatic environment (Heyer, 1969), protection of eggs and embryos from desiccation and thermal damage (Gorzula, 1977;Heyer, 1969;Hö dl, 1986), floatation for aquatic eggs (Haddad and Hö dl, 1997), protection from aquatic predators and cannibals (Hö dl, 1990; but see Altig, 1996 andMenin andGiaretta, 2003), and enhanced oxygenation of the eggs and embryos either from being held near the meniscus (Haddad and Hö dl, 1997) or from the air trapped in the bubbles per se.…”

“…The bubbles are formed in two different ways. Some female limnodynastids (Tyler and Davies, 1979;Williams and Tyler, 1994), with flanges on some fingers, place their hands successively above the water and then paddle down and back to propel bubbles along their bellies; the bubbles float upwards under the surface film of oviposited eggs (Fig. 5A).…”

The first part of this synthesis summarizes the morphology of the jelly layers surrounding an amphibian ovum. We propose a standard terminology and discuss the evolution of jelly layers. The second part reviews the morphological diversity and arrangement of deposited eggs-the ovipositional mode; we recognize 5 morphological classes including 14 modes. We discuss some of the oviductal, ovipositional, and postovipositional events that contribute to these morphologies. We have incorporated data from taxa from throughout the world but recognize that other types will be discovered that may modify understanding of these modes. Finally, we discuss the evolutionary context of the diversity of clutch structure and present a first estimate of its evolution.

“…I). The foam (TYLER & DAVIES 1979). The more complex foam nests are those built by Hyperolidae, Leiuperidae, Leptodactylidae, and Rhacophoridae whose eggs are surrounded by many small air bubbles, being deposited on the water surface (HEYER 1969, HÖDL 1992 or on leafs/litter (JENNIONS et al 1992, KADADEVARU & KANAMADI 2000.…”
