Barboza & Bohs, , a new species from the tropical wet forests of the eastern Andean slopes (Colombia, Ecuador, and Peru) is described and illustrated. This new species belongs to the Andean clade (all species 2n = 26) of and is similar to Barboza & S.Leiva in its glabrescence, calyx morphology, and corolla and seed color but differs in its membranous and elliptic leaves, fleshy calyces, deeper stellate corollas, longer filaments, longer and purple fruiting pedicels, purple berries, and larger seeds. Its chromosome number was counted (2n = 26), a preliminary assessment of conservation status is given and discussed, and an updated identification key to the species of the Andean clade is provided.

Dendropsophusis one of the most species-rich genera of hylid treefrogs. Recent studies integrating Sanger-generated mitochondrial and nuclear loci with phenomic characters (SP) have advanced understanding of this clade, but questions about its internal relationships and biogeographic history persist. To address these questions, we used anchored hybrid enrichment (AHE) to combine 432 nuclear loci for 78 taxa (72 % of species) with published data.

The tropical Andes are known as a biodiversity hotspot with the highest percentage of endemic plants and vertebrates in the world. The Andean genera Leptopeltus Bernhauer and Leptopeltoides Chani-Posse & Asenjo contain six and four species respectively, most of which occur in the Andean highlands near 3000 m. Here, we describe two new species of the subtribe Philonthina, recently discovered in the northern Peruvian Andes: Leptopeltus dieguezi sp.

The new species is closely related to H. tapichalaca and is part of the southern clade of the H.

The spatial and environmental features of regions where clades are evolving are expected to impact biogeographic processes such as speciation, extinction, and dispersal. Any number of regional features (such as elevation, distance, area, etc.) may be directly or indirectly related to these processes.

Chytridiomycosis is a fungal disease responsible for massive amphibian die-offs worldwide, caused by the fungus (Bd). Potential symbiotic relationships between frogs and the bacteria residing on their skin-referred to as skin-bacteria-may inhibit Bd growth, aiding in resistance to this lethal disease. This research had three main objectives: (1) to detect the presence of Bd in native populations of , and in the central Andes and coastal southern regions of Ecuador; (2) to identify the culturable skin-bacteria; and (3) to analyze differences among the bacterial communities in the three species studied.
