Cities can host significant biological diversity. Yet, urbanisation leads to the loss of habitats, species, and functional groups. Understanding how multiple taxa respond globally is essential promote conserve biodiversity in cities. Using a dataset encompassing six terrestrial faunal (amphibians, bats, bees, birds, carabid beetles reptiles) across 379 cities on 6 continents, we show that produces taxon-specific changes trait composition, with traits related reproductive strategy showing...
We describe two new species of the genus Pristimantis from western margin Eastern Cordillera Colombia. The have a sympatric distribution and are found in humid tropical forests lower part Tamá National Natural Park (PNN Tamá) its buffer zone. were described morphological comparisons phylogenetic reconstruction sequencing three mitochondrial nuclear genes. With these species, number known department Norte de Santander has increased to 10. In addition, we included sequences for P. anolirex,...
Tachiramantis is a recently proposed genus that includes seven species, four considered threatened with declining trend, while three lack sufficient data for conservation assessment. The Guacharaquita frog lentiginosus one of these substantial information gaps regarding its natural history, threats, and population density changes, particularly in isolated populations such as studied here. In San Antonio, the only location Colombia where T. found, we evaluated changes vegetation cover over 10...

Colombia is the country with highest bird diversity in world. Despite active research ornithology, compelling morphological information of most species still sparse. However, baseline to understand how respond environmental variation and ecosystems loss. As part a national initiative, Instituto Alexander von Humboldt collaboration 12 Colombian institutions seven biological collections, measured up 15 traits 9,892 individuals corresponding 606 species: 3,492 from captured field 6,400 museum...
Knowledge of Andean anurans is constantly increasing; for this reason, it needs an update. We reviewed scientific literature and museum records to determine the species richness in northern Andes their conservation status based on IUCN categories. The harbor 740 anurans, belonging 13 families 63 genera. family with highest number was Craugastoridae (334 spp.), followed by Bufonidae (92 Centrolenidae (81 spp.). Cordillera Central Colombia harbors (199 while de la Costa Oriental Venezuela...
El Loro orejiamarillo (Ognorhynchus icterotis) es una especie casi endémica que tenía distribución histórica a lo largo de los Andes colombianos y ecuatorianos. Sin embargo, para finales la década 90’s sus poblaciones declinaron drásticamente, debido fragmentación pérdida del hábitat, dando lugar su extinción en Ecuador reducción considerable ámbito Colombia. Se cree población ha aumentado últimos años el país, gracias procesos conservación, hallazgo nuevas localidades, fue fundamental bajar...
Presentamos una estimación de la riqueza potencial y las implicaciones para conservación especies altoandinas anuros mariposas diurnas, distribuidas en los departamentos Norte Santander Santander. Durante junio 2012 mayo 2016 se realizaron muestreos campo unidades biogeográficas Almorzadero, Santurbán Tamá, registrar datos presencia siete anfibios del orden Anura 29 superfamilia Papilionoidea. Realizamos modelamientos distribución cada especie, convertimos modelo binario, suma únicas por...
We provide the first record of Visored bat Sphaeronycteris toxophyllum for department Boyacá, Colombia, in Eastern Cordillera. This is based on a female collected secondary forest at an altitude 1,100 m. External and skull measurements obtained this specimen generally agree with those reported literature other Colombian specimens. With present record, poorly known fauna Boyacá can be recognized as including least 34 species.
Dendropsophus meridensis is a medium-sized treefrog endemic to the Cordillera de Mérida in Venezuelan Andes. The geographic distribution of this species poorly known, and only 10 localities known literature. Most these do not have associated coordinates altitude. In note we provide eight new locality records map D. meridensis, based on field work, revision museum collections, modeling. Three were found after performing Additionally, some comments natural history color variation are included.
Cities can host significant biological diversity. Yet, urbanisation leads to the loss of habitats and, potentially, local extinctions. Understanding how multiple taxa respond globally is essential promote and conserve biodiversity in cities surrounding landscapes. Using a dataset with site-level occurrence trait data 5302 species from six terrestrial fauna taxonomic groups across 379 on 6 continents, we show that produces taxon-specific changes composition, traits related reproductive...
The Neotropical genus Allobates Zimmerman & (1988) is a large monophyletic clade composed of 54 described species distributed between Central America and South (Frost, 2019; Grant et al., 2017). Twelve have been recorded in Colombia, mostly the eastern flank Eastern Cordillera Amazonian Region, although some reach Magdalena Valley Western (Acosta-Galvis,
Introducción: no hace mucho en Colombia se inició la tarea de identificar y crear soluciones que garanticen protección fauna o seres sintientes; es por ello tanto profesionales como investigadores, han abordado un alto estudio doctrinal medio del cual logre estructurar una nueva categoría hacia los animales, pero sin desconocer las bases fundamentales estado social derecho. Objetivo: planteó objetivo, asentar visión teórica silvestre. Materiales Métodos: el arte metodología investigación...
