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

• Carlos E. Guarnizo, Adolfo Amézquita, Eldredge P Bermingham
• 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… (More)

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

• Álvarez, Carlos E. Guarnizo, Andrew J. Crawford
• 2015

Results The phylogeny of Rheobates is largely predicted by geography, with one population from the eastern flank of the Eastern Cordillera sharing a most recent common ancestor with all other… (More)

Geographic Variation in Advertisement Call and Genetic Structure of Colostethus Palmatus ( Anura , Dendrobatidae ) from the Colombian Andes

• Ximena E Bernal, Carlos E. Guarnizo, Horst Lüddecke
• 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… (More)

DNA Barcoding Survey of Anurans across the Eastern Cordillera of Colombia and the Impact of the Andes on Cryptic Diversity

• Carlos E. Guarnizo, Andréa Maria Rolim da Paz, +4 authors Jésus E. Maldonado
• PloS one
• 2015

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… (More)

Cryptic lineages and diversification of an endemic anole lizard (Squamata, Dactyloidae) of the Cerrado hotspot.

• Carlos E. Guarnizo, Fernanda P Werneck, +10 authors Guarino R Colli
• 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… (More)

Geographic determinants of gene flow in two sister species of tropical Andean frogs.

• Carlos E. Guarnizo, David C Cannatella
• The Journal of heredity
• 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… (More)

Comparing evolutionary rates between trees , clades and traits Liam

• James Revell, E. González-Valenzuela, Luisa A. Castellanos-García, Carlos E. Guarnizo, Andrew J. Crawford
• 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… (More)
