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 ...
Phylogeny, evolution and ecological speciation analyses of Imperata (Poaceae: Andropogoneae) in the Neotropics
(Cambridge University Press, 2021-03)
Imperata is a ubiquitous grass genus of the tribe Andropogoneae (Poaceae), distributed throughout the world. Previous systematic studies had established that the genus encompasses nine species although no phylogenetic ...
Ecological and Spatial Patterns Associated with Diversification of the Shrub Genus Tetraglochin along Southern-Central Andes (Rosaceae)
(Springer, 2019-02-26)
In addition to the degree of geographical isolation (sympatry, parapatry, allopatry and peripatry), ecology can be an important factor promoting diversification of lineages, both by niche divergence as well as niche ...
Intraspecific ecological niche divergence and reproductive shifts foster cytotype displacement and provide ecological opportunity to polyploids
(Oxford University Press, 2018-05)
Background and Aims Niche divergence between polyploids and their lower ploidy progenitors is one of the primary mechanisms fostering polyploid establishment and adaptive divergence. However, within-species chromosomal and ...
Changing Only Slowly: The Role of Phylogenetic Niche Conservatism in Caviidae (Rodentia) Speciation
(Springer, 2020-04)
The dynamics of species diversification have attracted significant scientific attention in recent decades. Many lineages tend tomaintain their niche characteristics over evolutionary time, a phenomenon known as phylogenetic ...
Niche divergence among closely related taxa provides insight on evolutionary patterns of ticks
(Wiley, 2021-09)
Aim: Understanding the degree to which closely related taxa diverge in their niche traits could provide insight on their evolutionary patterns, as well as shed some light on the mechanisms underpinning broad-scale biogeographic ...
Competition and resource breadth shape niche variation and overlap in multiple trophic dimensions
(2019-05-15)
Competition plays a central role in the maintenance of biodiversity. A backbone of classic niche theory is that local coexistence of competitors is favoured by the contraction or divergence of species' niches. However, ...
Change of niche in guanaco (Lama guanicoe): the effects of climate change on habitat suitability and lineage conservatism in Chile
(PEERJ, 2018)
Background: The main goal of this contribution was to define the ecological niche of the guanaco (Lama guanicoe), to describe potential distributional changes, and to assess the relative importance of niche conservatism ...
