“…As well as the retreat of the glaciers, the decline of snow and ice in the Andes [151][152][153]. Other authors have studied its forests and their diversity [154], freshwater ecosystems [155], as well as the discovery of new species [156][157][158][159][160][161][162][163]. Due to the importance of the Galapagos Islands, water security and water quality have been studied [164][165][166], the impact on fishery resources [167,168], damage caused by plastic waste [169], the effects on the soils of complex agrosystems [170] and air quality [171].…”

Ecuador has shown a growth in its scientific production since 2011, representing 85% of the total historical production. These investigations are reflected in scientific publications, which address world interest topics and serve as a link for the university, business, and society. This work aims to analyze the scientific production generated by Ecuador in the period of 1920–2020 using bibliometric methods to evaluate its intellectual structure and performance. The methodology applied in this study includes: (i) terms definition and search criteria; (ii) database selection, initial search, and document compilation; (iii) data extraction and software selection; and finally, (iv) analysis of results. The results show that scientific production has been consolidated in 30,205 documents, developed in 27 subject areas, in 13 languages under the contribution of 84 countries. This intellectual structure is in harmony with the global context when presenting research topics related to “Biology and regional climate change”, “Higher education and its various approaches”, “Technology and Computer Science”, “Medicine”, “Energy, food and water”, and ”Development and applications on the Web”. Topics framed in the Sustainable Development Goals (SDGs), sustainability, climate change, and others. This study contributes to the academic community, considering current re-search issues and global concerns, the collaboration between universities and countries that allow establishing future collaboration links.

“…Including the two new species described herein, the herpetological exploration of the Andes from northern Peru in the last three decades has resulted in the discovery of 35 species of lizards belonging to ten genera (i.e. two species of Ameiva Meyer, 1795, one Cercosaura Wagler, 1830, six Enyalioides , two Macropholidus Noble, 1921, two Petracola Doan & Castoe, 2005, one Pholidobolus Peters, 1863, one Polychrus Linnaeus, 1758, three Phyllodactylus Gray, 1828, one Phyllopezus Peters, 1877, and sixteen Stenocercus ) (Cadle 1991, 1998, 2001, Cadle & Chuna 1995, Torres-Carvajal 2005, Koch et al 2006, 2011, 2013, 2016, Venegas et al 2008, 2013a, b, 2014, 2016a, b, 2020, 2022, Echevarría & Venegas 2015, Echevarría et al 2015, 2021, Torres-Carvajal et al 2015, 2020, Rodríguez & Mamani 2020). Most of these species are known from a few localities restricted or adjacent to the Huacabamba Depression, which represents a complex orographic scenario where Andean mountain ranges are separated by deep valleys (Duellman & Pramuk 1999).…”

Based on morphological features, genetic distances, and phylogenetic relationships, we report the discovery of two new species of Enyalioides from the montane forest of Cordillera de Colán in northern Peru. The first new species can be distinguished from its congeners by the combination of the following characters: scales immediately posterior to superciliaries on lateral edge of skull conical, slightly higher than adjacent scales; gular scales heterogeneous in size; scales on neck mostly large and conical; dorsal scales between dorsolateral crests covered by large, keeled, mucronate scales; scales on flanks tiny, tuberculate or granular, with scattered enlarged conical or tuberculate scales; ventral scales keeled or feebly keeled; caudal scales heterogeneous, increasing in size posteriorly on each segment; and marked sexual dichromatism. Among other features, the second new species differs from other Enyalioides in having a distinctively low vertebral crest; scales immediately posterior to superciliaries on lateral edge of skull barely projected and similar in height to adjacent scales; 56-71 vertebral scales from occiput to base of tail; dorsal scales feebly keeled and heterogeneous in size; ventral scales keeled; and caudal scales heterogeneous, increasing in size posteriorly on each segment. In addition, we present an updated identification key for species of Hoplocercinae.

“…The Huancabamba Depression has long been considered a major biogeographic barrier to the north-south dispersal of some Andean organisms [43][44][45] and a migration corridor for others [46,47]. The Huancabamba Depression may have influenced the radiation of several Andean genera of lizards, such as Andinosaura, Macropholidus, Petracola, Pholidobolus, Riama, and Stenocercus [43,45,[48][49][50][51][52][53]. For amphibians, the Huancabamba Depression is the southernmost limit for the radiation of Lynchius [13] and may be the northernmost limit for Phrynopus (see Chávez et al [54]; Venegas et al [21]).…”

We describe two new species of terrestrial-breeding frogs from the Cordillera de Colán, in northeastern Peru. We used Parsimony and Maximum Likelihood approaches to infer a molecular phylogeny on a dataset composed of 75 terminals, including three terminals representing the new species, and 4202 bp of concatenated mtDNA and nuDNA fragments. Our phylogenetic analyses support the placement of the two new species in Lynchius and Oreobates, respectively. The new species of Lynchius occurs in two localities from 1,977 to 2,006 m a.s.l., and is characterized by having a dorsum covered by conical tubercles and a brown dorsal coloration lacking a pattern of blotches on the hidden surfaces of flanks and hindlimbs. The new species of Oreobates is only known from one location at 2608 m a.s.l. and is characterized by the absence of axillary and inguinal glands, and the presence of white or cream blotches on the dark brown hidden surfaces of the body.
