This is the opening paper in the special issue of Fungal Diversity, which collates the data on
defining species. Defining and recognizing species has long been a controversial issue …

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 …

Delimiting and naming biodiversity is a vital step toward wildlife conservation and research.
However, species delimitation must be consistent across biota so that the limited resources …

True fungi (Fungi) and fungus-like organisms (eg Mycetozoa, Oomycota) constitute the
second largest group of organisms based on global richness estimates, with around 3 …

The multispecies coalescent model underlies many approaches used for species
delimitation. In previous work assessing the performance of species delimitation under this …

Thousands of small populations are at increased risk of extinction because genetics and
evolutionary biology are not well‐integrated into conservation planning–a major lost …

The objective of this review is to update our previously published checklist of Recent
freshwater mussel species and genera (Graf & Cummings, 2007, J. Molluscan Stud.: 291 …

Palaeontologists characterize mass extinctions as times when the Earth loses more than
three-quarters of its species in a geologically short interval, as has happened only five times …

The species problem has triggered the publication of an almost infinite number of theoretical
and practical studies, including quite a number of books. I should, therefore, perhaps briefly …

Alternaria alternata is a common species of fungus frequently isolated from plants as both an
endophyte and a pathogen. Although the current definition of A. alternata rests on a …
