For almost 30 years, there have been active discussions about the taxonomic impediment
and the challenge this represents to address the current human-induced biodiversity crisis …

The science of taxonomy, albeit being fundamental for all organismic research, has been
underfunded and undervalued for about two generations. We analyze how this could …

Wild and managed bees are key pollinators, ensuring or enhancing the reproduction of a
large fraction of the world's wild flowering plants and the yield of∼ 85% of all cultivated …

The species of classical taxonomy are examined with a view to their future role in integrative
taxonomy. Taxonomic species are presented as the products of a cyclic workflow between …

Discovery of cryptic species using molecular tools has become common in many animal
groups but it is rarely accompanied by morphological revision, creating ongoing problems in …

Since nomenclature is intended to reflect the evolutionary history of organisms, advances in
our understanding of historical relationships may lead to changes in classification, and thus …

(Received 14 June 2019; accepted 23 September 2020) We examine notions of taxonomic
'impediment','gap','inflation'and 'anarchy', all of which are increasingly prevalent in …

In zoological nomenclature, to be potentially valid, nomenclatural novelties (ie, new nomina
and nomenclatural acts) need first to be made available, that is, published in works …

Bees (Hymenoptera: Apoidea, Apiformes) are taxonomically and ecologically diverse, with a
wide range of social complexity, nesting preferences, floral associations, and biogeographic …

Unravelling the evolutionary history of taxa requires solid delimitation of the traits
characterising these. This can be challenging especially in groups with a highly complex …
