The relative roles of vicariance versus elevational gradients in the genetic differentiation of the high Andean tree frog, Dendropsophus labialis.

- Molecular phylogenetics and evolution
- 2009
There are two main competing hypotheses (vicariance and vertical ecotones) that attempt to explain the tremendous diversity of the tropical Andes. We test these hypotheses at the intraspecific level… Expand
DNA Barcoding Survey of Anurans across the Eastern Cordillera of Colombia and the Impact of the Andes on Cryptic Diversity

Colombia hosts the second highest amphibian species diversity on Earth, yet its fauna remains poorly studied, especially using molecular genetic techniques. We present the results of the first… Expand
Congruence Between Acoustic Traits and Genealogical History Reveals a New Species of Dendropsophus (Anura: Hylidae) in the High Andes of Colombia

Abstract: The High-Andean Frog (Dendropsophus labialis) is distributed along the Eastern Andes of Colombia between 1900 and 3600 m. We analyzed multiple traits to determine if acoustics and… Expand
GEOGRAPHIC VARIATION IN ADVERTISEMENT CALL AND GENETIC STRUCTURE OF COLOSTETHUS PALMATUS (ANURA, DENDROBATIDAE) FROM THE COLOMBIAN ANDES
- Ximena E. Bernal, Carlos E. Guarnizo, H. Lüddecke
- Biology
- 1 December 2005
Among frogs endemic to the Colombian Andes, the dendrobatid Colostethus palmatus has an exceptionally wide geographic distribution. We examined the patterns of variation in calls and genetic… Expand
Of peaks and valleys: testing the roles of orogeny and habitat heterogeneity in driving allopatry in mid-elevation frogs (Aromobatidae: Rheobates) of the northern Andes

Aim
The frog genus Rheobates (Anura: Aromobatidae) is endemic to mid-elevations in the Colombian Andes. Our aim was to evaluate the role of the northern Andean high peaks and the low Magdalena… Expand
Cryptic lineages and diversification of an endemic anole lizard (Squamata, Dactyloidae) of the Cerrado hotspot.
- Carlos E. Guarnizo, F. P. Werneck, +10 authors G. Colli
- Biology, Medicine
- Molecular phylogenetics and evolution
- 2016
The Cerrado is a wide Neotropical savanna with tremendously high endemic diversity. Yet, it is not clear what the prevalent processes leading to such diversification are. We used the Cerrado-endemic… Expand
Genetic divergence within frog species is greater in topographically more complex regions
- Carlos E. Guarnizo, D. Cannatella
- Biology
- 1 November 2013
Most global hotspots of biodiversity and endemism are in montane regions. One explanation is that montane regions have intrinsically higher speciation rates than lowland regions because complex… Expand
Comparing evolutionary rates between trees, clades and traits
- L. Revell, Laura E. González‐Valenzuela, Alejandro Alfonso, Luisa A. Castellanos‐García, Carlos E. Guarnizo, A. J. Crawford
- Biology
- 1 April 2018
At least since Simpson (1944), if not before, evolutionary biologists have been fascinated by the tempo or rate of evolutionary change through time. Studies of changes in evolutionary rate have grown… Expand
Geographic determinants of gene flow in two sister species of tropical Andean frogs.

- Biology, Medicine
- The Journal of heredity
- 1 March 2014
Complex interactions between topographic heterogeneity, climatic and environmental gradients, and thermal niche conservatism are commonly assumed to indicate the degree of biotic diversification in… Expand
Environmental ranges estimated from species distribution models are not good predictors of lizard and frog physiological tolerances
- A. Paz, Carlos E. Guarnizo
- Biology
- Evolutionary Ecology
- 27 November 2019
Using species ranges, in particular those derived from species distribution models (SDM), to obtain characteristics of the species’ niche such as temperature tolerances is tempting. Over the past… Expand
