Far too often, phenotypic divergence has been misinterpreted as genetic divergence, and based on phenotypic divergence, genetic divergence has been indicated. We have attempted to disprove this statement and call for the ...

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 ...

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 ...

Parallel phenotypic divergence is the independent differentiation between phenotypes of the same lineage or species occupying ecologically similar environments in different populations. We tested in the Antarctic limpet ...

In island-like habitats, geographic isolation facilitates population and speciesdivergence by constraining gene flow, while environmental isolation can enhancedivergence. We tested the relative contribution of geographic ...

Mimulus luteus (Scrophulariaceae) is a perennial herb occurring in the South American Andes that shows a wide variation in the size and shape of a red spot on the lower lobe of the yellow flower. We describe the preference ...

In this article we study the phenotypic structure, biological relationships and evolutionary factors that acted on the biological diversity observed in the prehistoric groups that inhabited Northwest Argentina (NWA). The ...

Dispersers are not a random subset of the source population, and there is considerable evidence that they differ from non-dispersers in a number of phenotypic traits. However, it is not clear whether the magnitude and ...
