“…Fecundity was positively correlated with average female size across species (see Fig 6 ), a relationship that has also been observed at an intraspecific level in Eleutherodactylus atkinsi (Alfonso et al. 2017 ). Fecundity was also positively correlated, to a lesser extent, with the size of males.…”

“…Furthermore, femalebiased SSD could be exacerbated by sexual selection if males exhibit a preference based on female size, although as far as we know there are no data supporting this possibility.

“…In addition, we compiled information on the fecundity of 89 of the species from the literature: size of the clutches, number of eggs in the oviducts, or number of juveniles (Table S3). We chose to use the maximum value of those described in the literature, being cautious to avoid considering multiple clutches, of one or several females, as has been recorded to occur in Caribbean Eleutherodactylus (Henderson and Powell 2009;Ríos-López et al 2016;Alfonso et al 2017). Similarly, we also compiled literature information on parental care for 40 species, classifying care into five categories: maternal, paternal, biparental, uncertain (no caring sex specified), or absent (Table S3).…”

Influence of microhabitat, fecundity, and parental care on the evolution of sexual size dimorphism in Caribbean Eleutherodactylus frogs

et al. 2022

Rensch's rule suggests that sexual size dimorphism (SSD) increases with species size when males are the larger sex, whereas it decreases when females are the larger sex. However, the process responsible for this pattern remains obscure. SSD can result from sexual selection, such as intrasexual competition for access to mates, or from natural selection, due to resource partitioning or fecundity selection. We studied SSD in Caribbean Eleutherodactylus frogs using phylogenetic comparative methods to investigate the influence of microhabitat, fecundity, and parental care. Our results show that in Caribbean Eleutherodactylus females tend to be larger and, contrary to Rensch's rule, dimorphism increases with species size. SSD was not related to microhabitat use. However, SSD was positively correlated with fecundity, mediated by a greater increase in female size. SSD was also influenced by parental care, suggesting that male care promotes larger male size and reduces the female bias in SSD. As suggested for other anurans, female‐biased SSD in Caribbean Eleutherodactylus results from fecundity selection, although the magnitude is countered by increased male size in species with paternal care. Our results highlight the importance of considering various selective forces that may act in concert to influence the evolution of SSD.

“…Herein, we describe, for what we believe is the first time, three clutches at the same site. Communal oviposition has been suggested for three other Cuban species, the Cuban Giant Frog (E. zeus) (Alonso et al 2015), Cuban Groin-spotted Frog (E. atkinsi) (Alfonso et al 2017), and Cuban Flatheaded Frog (E. planirostris) (Iturriaga and Dugo-Cota 2018). These observations collectively suggest that multiple clutches deposited at the same breeding site may be more common in species of Eleutherodactylus than what has been documented (e.g., Townsend et al 1984;Burrowes 2000;Ríos-López et al 2016).…”

T he seven species of Cuban frogs in the Eleutherodactylus varians species-group, which spend most of their lives in bromeliads, are characterized by moderate size (28-40 mm SVL), large and rounded digital discs, and a tan, brown, or greenish-brown dorsum, some with mottling or bold patterns (Hedges et al. 2008). Ecologically classified as arboreal and bromeliad-dwelling species by Díaz and Cádiz (2008, p. 19 and their Fig. 6), these frogs take refuge in bromeliads and reproduce and lay eggs in them, often high above the ground, and males call from bromeliads and leaves in the canopy (Díaz and Cádiz 2008;Henderson and Powell 2009).The Oriente Bromeliad Frog (Eleutherodactylus ionthus) is endemic to southeastern Cuba (Díaz and Cádiz 2008), where it occurs in evergreen, pine, cloud, and rainforests (Díaz and Cádiz 2008) and in coastal semideciduous forests and xeromorphic scrub (Fong 2005). Males call throughout the night and occasionally during the day (Díaz et al. 2005; Díaz and Cádiz 2008). However, very little is known about reproduction in this frog (see the account in Henderson and Powell 2009).The Guantanamera Frog (Eleutherodactylus guantanamera; Fig. 1), with a range restricted to the Sierra del Cobre, Sierra de La Gran Piedra, and Sagua-Baracoa Mountains (Díaz and Cádiz 2008), inhabits both primary (rainforest, semideciduous forest, pine forest, gallery forest) and secondary forests (timber and coffee plantations, roadside vegetation) (Díaz and Cádiz 2008;Fong 2008). Males call at night from high (typically ≥ 3 m) in trees (Hedges et al. 1992;Díaz and Cádiz 2008). Information on reproduction is summarized in Díaz and Cádiz (2008) and Henderson and Powell (2009). Clutches of 5-9 eggs (inferred from the number of ova in two large females; Hedges et al. 1992) are laid in bromeliads and usually attended by males. However, Díaz and Cádiz (2008) included a photograph (plate 24G) of a male guarding a clutch of 12 eggs laid in the axil of a bromeliad. Note that the account of the Cuban Bromeliad Frog (E. varians) in Henderson and Powell (2009) included data published by Estrada (1990) on clutches found at La Melba and La Naza, two localities in the Sagua-Baracoa Range in Holguín Province (near our site in Arroyo Bueno; see below). At the time of Estrada's paper, E. guantanamera had not been described and all bromeliad frogs were assigned to E. varians. Because both of Estrada's study sites are in the range of E. guantanamera, as in Díaz and Cádiz (2008) and Rivalta et al. (2014), we consider Estrada's data applicable to E. guantanamera (see below).Herein, we provide the first data on clutches, neonates, and parental care in E. ionthus and we report additional information on clutches and egg-deposition sites, including communal oviposition, in E. guantanamera.
