The species concept is the cornerstone of biodiversity science, and any paradigm shift in the
delimitation of species affects many research fields. Many biologists now are embracing a …

Recently, the “mountain-geobiodiversity hypothesis”(MGH) was proposed as a key concept
for explaining the high levels of biodiversity found in mountain systems of the Tibeto …

Disentangling the biogeographic patterns of rare and abundant microbes is essential in
order to understand the generation and maintenance of microbial diversity with respect to …

Aim Many important patterns and processes vary across the phylogeny and depend on
phylogenetic scale. Nonetheless, phylogenetic scale has never been formally …

Aim A predictive understanding of the mechanisms underlying microbial biogeographical
patterns is of great interest, particularly with respect to phylogenetic distributions of their …

Polyploid speciation entails substantial and rapid postzygotic reproductive isolation of
nascent species that are initially sympatric with one or both parents. Despite strong …

The latitudinal diversity gradient (LDG), where the number of species increases from the
poles to the Equator, ranks among the broadest and most notable biodiversity patterns on …

Growing evidence for lineage diversification that occurs without strong ecological
divergence (ie, nonadaptive radiation) challenges assumptions about the buildup and …

Aim Whether the gradients of global diversity conform to equilibrium or non‐equilibrium
dynamics remains an unresolved question in ecology and evolution. Here, we evaluate four …

The geographic distribution of plant diversity matches the gradient of habitat heterogeneity
from lowlands to mountain regions. However, little is known about how much this …
