Locomotor performance of closely related Tropidurus species: relationships with physiological parameters and ecological divergence
(Company of Biologists Ltd, 2004-03-01)
Tropidurid lizards have colonized a variety of Brazilian open environments without remarkable morphological variation, despite ecological and structural differences among habitats used. This study focuses on two Tropidurus ...
Ecological divergence and synchronous Pleistocene diversification in the widespread South American butter frog complex
(2022-04-01)
Phylogeographic studies primarily focus on the major role of landscape topography in driving lineage diversification. However, populational phylogeographic breaks may also occur as a result of either niche conservatism or ...
Body size and genetic variation in the White-tipped Plantcutter (Phytotoma rutila: Cotingidae) suggest ecological divergence across the Chaco–Andes dry forest belt
(Springer, 2019-09)
Dry forests characterize many of the biomes of southern South America and the Andes, such as the Chaco and the inter-Andean valley forests, which form a continuous belt (Chaco–Andes dry forest belt). Some of the taxa that ...
Morphological and genetic divergence of a small stream fish species along a watershed
(Biochemical Systematics and Ecology, 2018)
Testing Wallace's intuition: water type, reproductive isolation and divergence in an Amazonian fish
(Wiley-Blackwell, 2018-06-01)
Alfred Russel Wallace proposed classifying Amazon rivers based on their colour and clarity: white, black and clear water. Wallace also proposed that black waters could mediate diversification and yield distinct fish species. ...
Testing the divergence-with-gene flow model of ecological speciation in two species of andean hummingbirds
(UniandesMaestría en Ciencias BiológicasFacultad de CienciasDepartamento de Biología, 2010)
The divergence-with-gene-flow model of ecological speciation proposes speciation can proceed despite genetic interchange in populations distributed along environment al gradients, where variable selective regimes act on ...

Divergence in coloration and ecological speciation in the Anolis marmoratus species complex
Adaptive divergence in coloration is expected to produce reproductive isolation in species that use colourful signals in mate choice and species recognition. Indeed, many adaptive radiations are characterized by differentiation ...
