Inferring possible population divergence in Espeletia pycnophylla (Asteraceae) through morphometric and paleogeographic approaches
(Universidad de Costa Rica, 2010)
Genetic divergence in tropical anurans: deeper phylogeographic structure in forest specialists and in topographically complex regions
(Springer, 2015-09-01)
Many tropical organisms show large genetic differences among populations, yet the prevalent drivers of the underlying divergence processes are incompletely understood. We explored the effect of several habitat and natural ...
Leaf morphological and genetic divergence in populations of Drimys (Winteraceae) in Chile
(Elsevier, 2012)
The genus Drimys is distributed in Chile from semi-arid zones to sub-Antarctic forests; there are three species of this tree, D. andina, D. confertifolia and D. winteri, the latter with varieties chilensis and winteri. ...
Allozymatic divergence between border populations of two cryptic species of the Drosophila buzzatii cluster species (Diptera: Drosophilidae)
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
Drosophila antonietae and Drosophila gouveai are allopatric, cactophilic, cryptic and endemic of South America species, which aedeagus morphology is considered the main diagnostic character. In this work, single close ...
Functional morphology of the tetra fish Astyanax lacustris differs between divergent habitats in the Pantanal wetlands
(Wiley-Blackwell, 2016-08-01)
This study investigated whether the body morphology of the tetra fish Astyanax lacustris ( previously Astyanax asuncionensis) varied between populations inhabiting one lagoon ( a lentic, shallow environment, with great ...
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 ...
Patterns of Z chromosome divergence among Heliconius species highlight the importance of historical demography
(2018)
Sex chromosomes are disproportionately involved in reproductive isolation and adaptation. In support of such a “large-X” effect, genome scans between recently diverged populations and species pairs often identify distinct ...
