Oviposition Site Selection in Three Glass Frog Species
Copeia, 2020Oviposition site selection is critical for the reproductive success of oviparous organisms. We investigated oviposition site selection in three species of glass frogs—Espadarana prosoblepon, Hyalinobatrachium valerioi, and Teratohyla spinosa—in northeastern Costa Rica.

Abstract Centrolenidae is a monophyletic group of Neotropical tree frogs. Centrolenid tadpoles usually lack pigmentation on their bodies, presenting reddish coloration in life, and are fossorial. Several phenotypic characters have been associated with fossoriality, but data on larval morphology is scarce.

A NEW SPECIES OF GLASS FROG (ANURA: CENTROLENIDAE) FROM THE VENEZUELAN GUAYANA
Herpetologica, 2003A new species of Centrolene is named from the La Escalera Region in Estado Bo- livar, Venezuela. The three species known from the Guianan Region of northeastern South America represent a single clade characterized by a white bib-like parietal peritoneum; this clade is referred to as the Centrolene gorzulai species group.

AbstractThe morphology and organization of chromatophores in the neotropical glass‐frog, Centrolenella fleischmanni (family Centrolenidae), were studied with both light and electron microscopes. Four types of pigment cells are described in the dorsal skin.

A NEW SPECIES OF GLASS FROG (CENTROLENIDAE: COCHRANELLA OCELLATA GROUP) FROM CENTRAL PERU
Herpetologica, 2006We describe a new species of Cochranella from the Cordillera de Carpish, Departamento Huanuco, Peru. The new species is placed in the Cochranella ocellata group and can be distinguished from all other species of Cochranella by having: (1) small white and dark purple spots on the dorsum; (2) a snout slightly protruding to truncate in lateral aspect; (3)

Males of the glass frog Hyalinobatrachium valerioi engage in diurnal and nocturnal attendance of egg clutches. To study the effect of parental care on embryonic survivorship, we conducted a male removal experiment and measured embryonic survival rates on day 4, 8, and 12 after oviposition in attended and unattended clutches.

A Remarkable New Glass Frog (Centrolenidae:Vitreorana) from the Northeast Atlantic Forest, Brazil
Herpetologica, 2014Abstract: We describe a new species of glass frog (Vitreorana) from Fazenda Novo Pau Brasil, in the Atlantic Forest habitat of northeastern Brazil. Previous to this work, Vitreorana baliomma sp. nov. was misidentified as V. eurygnatha, from which it can be distinguished by the iris pattern flecked with star-shape melanophores; rudimentary nuptial ...

Bolivian glass frogs (Anura: Centrolenidae) with a description of a new species from Amazonia
Proceedings of the Biological Society of Washington, 2005ABSTRACT We describe a new species of Cochranella from the Serrania de Huanchaca, Bolivia. The new species possesses a suite of unusual characteristics, most notably dermal glands along its fingers and toes. Cochranella spiculata is reported from Bolivia and we describe the females of that species. New material of C. bejaranoi from Chuquisaca collected

Embryonic development is often a dangerous period of the life cycle for many organisms and embryos are often viewed as helpless. Parental care can help reduce mortality in early life stages but embryonic behavior itself can also be important. To assess the ability of frog embryos to actively hatch in response to environmental cues, we conducted an ...
