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 ...

Major histocompatibility complex (MHC) genes can be used to study molecular evolution in wild vertebrate populations. Here, we used “genome walking” to develop primers for amplification of the second exon of a single expressed MHC class II locus in a glass frog, Espadarana prosoblepon. We tested the utility of the primers on two Panamian populations of

Abstract Social behaviors often are context dependent; behaviors at high density may change or disappear at lower population densities. We analyzed spatial dispersion patterns and habitat associations at high and low population densities of male Espadarana (Centrolene) prosoblepon that declined following the invasion of a pathogenic fungus ...

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 ...

A new species of Hyperolius is described from Nyungwe National Park in southern Rwanda. The new species differs fromits congeners by a unique combination of morphological characters, including a light green dorsum and a transparentventral skin resembling glass frogs of the Neotropical family Centrolenidae, blue-coloured bones, reduced toe webbing ...
