“…This hypothesis need to be tested, but some suggestive examples supporting it involve clutches infested by dipterans in anurans whose clutches have a thick jelly layer: Espadarana andina (Rivero, 1968) (Cabanzo-Olarte et al 2013), Agalychnis annae (Villa and Townsend 1983), A. callidryas (Hughey et al 2011), Hyalinobatrachium fleischmanni (Villa 1977, Hayes 1991, H. valerioi (Vockenhuber et al 2008), Hyperolius lateralis Laurent, 1940 (Vonesh 2000), and Centrolene peristicta (Lynch and Duellman, 1973) (Salgado and Guayasamín 2018). In addition, two species of glass frogs in the study area (Centrolene savagei, "Centrolene" quindianum Ruiz-Carranza and Lynch, 1995) have clutches without or with only a thin jelly layer, respectively, but during our sampling and previous studies, we did not record fly larvae in their clutches (Rios-Soto et al 2017, 2020. In spite of said potential cost associated with infestation by fly larvae, comparative analyses and experimental evidence demonstrate for glass frogs that an egg clutch with a thick jelly layer and reduced parental care by females (as in N. grandisonae) exhibit a similar overall survivorship to egg clutches with a reduced jelly layer and extended parental care by males (Delia et al 2020).…”

Phenology and mortality of embryos in a Colombian population of Nymphargus grandisonae (Anura: Centrolenidae). Studies of phenology and natural history of anurans provide information useful for its conservation. This is particularly important in current scenarios of emergent diseases, high rates of deforestation, and climate change. We recorded the timing of breeding of the Glass Frog Nymphargus grandisonae and its relationship to precipitation and environmental temperature for four years in a population located in the Central Andes of Colombia, South America. In addition, we recorded the causes of mortality in egg clutches of this species. We quantified infestation by fly larvae and its impact on the survival of embryos. We found that the reproductive activity of N. grandisonae (number of males calling) was seasonal and occurred in months with highest precipitation. The main cause of embryo mortality in clutches was associated with the infestation by a spittlebug fly of the genus c.f. Cladochaeta (Drosophilidae). The survival of embryos in infested clutches was significantly lower than in those clutches not infested by fly larvae. Our results provide baseline data for the monitoring of anuran population dynamics in the Andean region using the glass frog N. grandisonae as a model system.

“…Glass frogs have a well-established reproductive mode consisting of the adherence of egg clutches on substrates overhanging water [92, 93]. Detailed quantitative data for most of these traits are absent for most species [9, 17, 18, 94–99]. Likewise, centrolenid tadpoles are poorly known and to date they have been formally described for less than 40 species of the 158 species known diversity (e.g.…”

The poverty of adult morphology: Bioacoustics, genetics, and internal tadpole morphology reveal a new species of glassfrog (Anura: Centrolenidae: Ikakogi) from the Sierra Nevada de Santa Marta, Colombia

Ikakogi is a behaviorally and morphologically intriguing genus of glassfrog. Using tadpole morphology, vocalizations, and DNA, a new species is described from the Sierra Nevada de Santa Marta (SNSM), an isolated mountain range in northern Colombia. The new taxon is the second known species of the genus Ikakogi and is morphologically identical to I . tayrona (except for some larval characters) but differs by its genetic distance (14.8% in mitochondrial encoded cytochrome b MT-CYB ; ca. 371 bp) and by the dominant frequency of its advertisement call (2928–3273 Hz in contrast to 2650–2870 Hz in I . tayrona ). They also differ in the number of lateral buccal floor papillae, and the position of the buccal roof arena papillae. Additionally, the new species is differentiated from all other species of Centrolenidae by the following traits: tympanum visible, vomerine teeth absent, humeral spines present in adult males, bones in life white with pale green in epiphyses, minute punctuations present on green skin dorsum, and flanks with lateral row of small, enameled dots that extend from below eye to just posterior to arm insertion. We describe the external and internal larval morphology of the new species and we redescribe the larval morphology of Ikakogi tayrona on the basis of field collected specimens representing several stages of development from early to late metamorphosis. We discuss the relevance of larval morphology for the taxonomy and systematics of Ikakogi and other centrolenid genera. Finally, we document intraspecific larval variation in meristic characters and ontogenetic changes in eye size, coloration, and labial tooth-rows formulas, and compare tadpoles of related species. Ikakogi tayrona has been proposed as the sister taxon of all other Centrolenidae; our observations and new species description offers insights about the ancestral character-states of adults, egg clutches, and larval features in this lineage of frogs.

“…Previous natural history accounts for centrolenids have suggested that reproduction primarily occurs during the wet season (Savage 2002), and a recent study of Centrolene quindianum found calling activity and oviposition to be greatest during wetter and cooler months during the wet season in Colombia (Rios-Soto et al . 2017). We observed strong effects of temperature and precipitation on breeding activity of four centrolenid species at La Selva, where calling behaviour was greatest on cool and wet nights.…”

Abstract:The river zonation hypothesis predicts that abiotic and biotic conditions along riparian gradients drive variation in animal communities. Glass frogs are a diverse group of Neotropical anurans that use riparian habitats exclusively for oviposition and larval development, but little is known about how glass frog communities are distributed across riparian gradients. Here, we measured glass frog community assembly across a gradient of riparian habitats from first- to fifth-order streams at La Selva Biological Station, Costa Rica. We performed repeated nocturnal frog calling surveys and built occupancy andN-mixture abundance models to test for varying patterns of species occupancy, community assembly, species richness (α-diversity) and species turnover (ß-diversity). We observed significant differences in patterns of species occupancy and community assembly across a stream-order gradient: occupancy of two species increased with stream order (Teratohyla pulverata,Hyalinobatrachium fleischmanni), one species decreased (Teratohyla spinosa), and one species did not vary (Espadarana prosoblepon). We evaluated four a priori hypotheses describing how α- and ß-diversity of centrolenids are shaped across the riparian gradient; our data were most consistent with a pattern of nested assemblages and increasing species richness along the riparian gradient. Species-specific patterns of occupancy and abundance resulted in assemblage-level differences consistent with theoretical predictions for highly aquatic organisms along riparian gradients.
