The number of species on Earth is one of the most fundamental numbers in science, but one
that remains highly uncertain. Clearly, more species exist than the present number of …

As part of the German Barcode of Life campaign, over 3500 arachnid specimens have been
collected and analyzed: ca. 3300 Araneae and 200 Opiliones, belonging to almost 600 …

One major challenge to delimiting species with genetic data is successfully differentiating
population structure from species-level divergence, an issue exacerbated in taxa inhabiting …

A short history of the Opiliones volume in 'Die Tierwelt Deutschlands' published by Martens
is presented. The area under consideration comprises Central Europe expanded by large …

Roughly 18,000 species are described annually as new to science, while estimated
extinction rates are comparable to or even exceeding these new discoveries. Considering …

DNA barcoding is particularly useful for identification and species delimitation in taxa with
conserved morphology. Pseudoscorpions are arachnids with high prevalence of …

Seed harvesting ants are ecosystem engineers that shape vegetation, nutrient cycles, and
microclimate. Progress in ecological research is, however, slowed down by poor species …

Although resolving phylogenetic relationships and establishing species limits are primary
goals of systematics, these tasks remain challenging at both conceptual and analytical …

This study presents a comprehensive survey of the extant diversity of harvestmen
(Arachnida: Opiliones), a pivotal taxon for biogeography and conservation studies, across …

Accurate species delimitation is fundamental to biology. Traditionally, species were
delimited based on morphological characters, sometimes leading to taxonomic uncertainty …
