Here we review how evolving species concepts have been applied to understand yeast
diversity. Initially, a phenotypic species concept was utilized taking into consideration …

Genomic regions determining sexual compatibility often display recombination suppression,
as occurs in sex chromosomes, plant self‐incompatibility loci and fungal mating‐type loci …

Speciation is the process by which barriers to gene flow evolve between populations.
Although we now know that speciation is largely driven by natural selection, knowledge of …

Organisms exhibit extensive variation in ecological niche breadth, from very narrow
(specialists) to very broad (generalists). Two general paradigms have been proposed to …

Testing among competing demographic models of divergence has become an important
component of evolutionary research in model and non-model organisms. However, the …

The endpoint of speciation has been viewed as complete isolation and the absence of gene
flow between species. If the influx of genes from another species is maladaptive because …

In the absence of recombination, the number of transposable elements (TEs) increases due
to less efficient selection, but the dynamics of such TE accumulations are not well …

In this article, Matute et al. report an experiment in which they generated eight interspecific
admixed populations using two species pairs of Drosophila. They found that in both species …

Deletions, duplications, insertions, inversions and translocations are commonly referred to
as structural variants (SVs). Fungal plant pathogens have compact genomes, facilitating the …

Anthropocene marks the era when human activity is making a significant impact on earth, its
ecological and biogeographical systems. The domestication and intensification of …
