Evidence for ecological divergence across a mosaic of soil types in an Amazonian tropical tree: Protium subserratum (Burseraceae).
Soil heterogeneity is an important driver of divergent natural selection in plants. Neotropical forests have the highest tree diversity on earth, and frequently, soil specialist congeners are distributed parapatrically. While the role of edaphic heterogeneity in the origin and maintenance of tropical tree diversity is unknown, it has been posited that natural selection across the patchwork of s...
متن کاملEcological Divergence and Reproductive Isolation in an Amazonian Tropical Tree: Protium
Premise of the study: The first microsatellite primers were developed for Protium subserratum (Engl.) Engl., a widespread Amazonian tree, to investigate genetic differentiation between populations found on clay, brown-sand and white-sand soils. Methods and Results: Seventeen primer pairs were identified from two individuals of Protium subserratum, found on white-sand and brown-sand soil types. ...
متن کاملStrikingly variable divergence times inferred across an Amazonian butterfly 'suture zone'.
'Suture zones' are areas where hybrid and contact zones of multiple taxa are clustered. Such zones have been regarded as strong evidence for allopatric divergence by proponents of the Pleistocene forest refugia theory, a vicariance hypothesis frequently used to explain diversification in the Amazon basin. A central prediction of the refugia and other vicariance theories is that the taxa should ...

متن کاملVariable elements of metacommunity structure across an aquatic-terrestrial ecotone
The Elements of Metacommunity Structure (EMS) framework gives rise to important ecological insights through the distinction of metacommunities into several different idealised structures. We examined the EMS in assemblages occupying a low-mountain river system in central Germany, sampled over three consecutive years. We compared the idealised distributions of assemblages in both the riparian fl...
