Diversity, biogeography, and reproductive evolution in the genus Pipa (Amphibia: Anura: Pipidae).

The genus Pipa is a species-poor clade of Neotropical frogs and one of the most bizarre-looking due to many highly derived anatomical traits related to their fully aquatic lifestyle. With their African relatives, they form the Pipidae family, which has attracted much attention, especially regarding its anatomy, reproductive biology, paleontology and biogeography. However, the actual diversity and phylogenetic relationships within Pipa remain poorly understood, and thus so do their historical biogeography and the evolution of striking features, such as the absence of teeth and endotrophy in some species.

Distribution, habitat suitability, conservation state and natural history of endangered salamander .

Background: Pandi's mushroom-tongue salamander () is one of the threatened amphibians in South America, as well as a flagship species for the Colombian conservation agenda. This species is endemic to the Andean cloud forests of the western slope of the Cordillera Oriental of Colombia, occurring only in the department of Cundinamarca within a narrow elevational range. At night, can be seen perching on the upper side of leaves at heights ranging from ground level to 2.

A new Terrarana frog of genus from an unexplored cloud forest from the eastern Andes, Colombia.

A new species of (Craugastoridae, subgenus Pristimantis) is described from a relict and unexplored cloud forest in the western slope from Cordillera Oriental of the Colombian Andes. The specific name was chosen by consensus expert scientists and local people. is easily distinguished from congeneric species by having a gray iris with black reticulations in life, subconical tubercles on the upper eyelid, the chin edged with irregular, dark-brown blotches, and conical heel tubercles.

Thermal tolerance and the importance of microhabitats for Andean frogs in the context of land use and climate change.

Global warming is having impacts across the Tree of Life. Understanding species' physiological sensitivity to temperature change and how they relate to local temperature variation in their habitats is crucial to determining vulnerability to global warming. We ask how species' vulnerability varies across habitats and elevations, and how climatically buffered microhabitats can contribute to reduce their vulnerability.

Description of a new diminutive Hyloxalus (Anura: Dendrobatidae: Hyloxalinae) from the Magdalena Valley of Colombia.

Using different sources of evidence (i.e., integrative taxonomy), we describe a new species of Hyloxalus, Hyloxalus arliensis sp.

A new species of (Gymnophiona, Caeciliidae) from the Magdalena valley region of Colombia.

A new species of the genus (Caeciliidae) from the western foothills of the Serranía de los Yariguíes in Colombia is described. is similar to and but differs from these species in having fewer primary annular grooves and a shorter body length. With this new species, the currently recognized species in the genus are increased to 35.

A morphological database for Colombian anuran species from conservation-priority ecosystems.

Species traits provide a strong link between an organism's fitness and processes at community and ecosystem levels. However, such data remain scarce for amphibians in the Neotropics. Colombia is the country with the highest number of threatened amphibians and the second greatest number of amphibian species worldwide.

Molecular insights into the phylogenetic placement of the poorly known genus Niceforonia Goin Cochran, 1963 (Anura: Brachycephaloidea).

Among New World direct-developing frogs belonging to the clade Brachycephaloidea (= Terraranae), there are several genera with uncertain phylogenetic placements. One notable example is the genus Niceforonia Goin Cochran 1963, which includes three species that are endemic to Colombia. Three specimens of the species Niceforonia nana were collected and for the first time the genus is included in a molecular phylogenetic analysis of mitochondrial (mtDNA; 12S and 16S) and nuclear (nucDNA; TYR and RAG1) markers.

Garman, 1888 in Colombia: its distribution and identification.

is reported for the first time for Colombia, corresponding to the tenth species of the species group occurring in the country. In collections, all specimens were identified as . Morphological, coloration, and ecological characters are provided to differentiate the two species in Colombia.
