Natural history collections are essential to a wide variety of studies in biology because they maintain large collections of specimens and associated data, including genetic material (e.g., tissues) for DNA sequence data, yet they are currently under-funded and collection staff have high workloads. With the advent of aggregate databases and advances in sequencing technologies, there is an increased demand on collection staff for access to tissue samples and associated data. Scientists are rapidly developing large DNA barcode libraries, DNA sequences of specific genes for species across the tree of life, in order to document and conserve biodiversity. In doing so, mistakes are made. For instance, inconsistent taxonomic information is commonly taken from different lending institutions and deposited in data repositories, such as the Barcode of Life Database (BOLD) and GenBank, despite explicit disclaimers regarding the need for taxonomic verification by the lending institutions. Such e...

A new arboreal species of the Chaunus veraguensis group is described for the humid montane forest of Madidi National Park, in northern Bolivia. The new species differs from other species in the group by the combination small size, long and slender extremities, webbed hands, conspicuous tympanic membrane, well developed parotoid glands, absence of large glands on dorsum and extremities, nuptial excrescences of males composed of pungent spines on dorsal surface of thumb, greenish-brown coloration on dorsum with red warts in life, and green iris. It is only known from two nearby localities in the Serranía Eslabón, Department La Paz. An operational key for species in the C. veraguensis group is provided.

A new species of the genus Pristimantis is described from Churi tepui, in the Chimanta massif, Estado Bolívar, Venezuela. The new species was discovered during the Muchimuk Expedition 2009, an ongoing speleological exploration of the Charles Brewer cave system, the largest sandstone cave on Earth. The species is known from only one female, collected near the mouth of the Muchimuk cave, in “non-gramineous tubiform meadows”. The new species can be distinguished from other Pristimantis on the highlands of the Guiana Shield by its unique coloration, indistinct tympanum, dorsal and ventral skin smooth, well-developed lateral fringes on the fingers and toes, and basal webbing on Toes III–V.

Ecuador has the biggest number of amphibian species per unit of area in the world (425 species in 276,840 km2). In the last decade, conservative estimates indicate that at least 26 species of Ecuadorian amphibians have declined or gone extinct. The reasons for this crisis are not clear but have been related to habitat destruction, climate change, and/or fungal disease such as the chytridiomycosis. The Río Palenque Science Center (RPSC) was among the last remnants of tropical rainforest in the western lowlands of Ecuador. Twenty years ago, investigations done by R. McDiarmid and others lead to the discovery of an amazing herpetofauna, including several undescribed species. However, the expansion of the agricultural frontier and transformation of the forest remnants into oil palm and banana plantations destroyed this site. Among the species identified from RPSC were five species of glass frogs (Family Centrolenidae): Centrolene prosoblepon, Cochranella spinosai, Hyalinobatrachium flei...

The Glassfrogs (Centrolenidae) are an apparently monophyletic group of Neotropical anurans that includes 136 described species. The phylogenetic relationships of the family with other clades are still poorly understood and at the moment the family can be defined only by shared apomorphies. The current generic concepts that recognize Centrolene, Cochranella and Hyalinobatrachium do not seem to reflect the true evolutive relationships of the family. Study of ca. 500 specimens from different localities across Central and South America shows the existence of new undescribed species, taxonomic and nomenclatural confusions, and the need to review and reconsider the intra and intergeneric and specific relationships of the Centrolenidae. We restrict the name Hyalinobatrachium petersi for a taxon from the lowlands of the Ecuadorian Choco and report the first records of Centrolene lemniscatum and Hyalinobatrachum ruedai from Ecuador. The discovery of a new species of the group of Centrolene g...

The dispersal ecology of Stemmadenia donnell-smithii was studied in the tropical dry forest zone of northwestern Costa Rica. Fruit was most abundant late in the dry season and was eaten by 22 species of birds, many of which are primar- ily insectivorous. Stomach-content analyses substantiated our observations. Total crop size per tree and rate of fruit opening were greatest in
