Introduction
I'm leading the arachnid lab at the Leibnitz Institute for the Analysis of Biodiversity Change in Hamburg and provide research avenues for young arachnophiles and senior researchers. I also curate the arachnid and myriapod collections at the Zoological Museum in Hamburg. I have a broad interest in arachnid and myriapod biodiversity, systematics, taxonomy and conservation. I'm also interested in collection management and promoting museum science in the broader community.

Gut content metabarcoding has provided important insights into the food web ecology of spiders, the most dominant terrestrial arthropod predators. In small invertebrates, like spiders, gut content analysis is often performed on whole body DNA extracts of individual predators, from which prey sequences are selectively enriched and sequenced. Since m...

Global arthropod decline demands effective biodiversity monitoring strategies. However, most current monitoring approaches do not provide an exhaustive picture of arthropod community structure. In particular, biotic interactions and temporal patterns of biodiversity change are still poorly understood due to a lack of suitable monitoring approaches....

During the Paleogene, the Holarctic experienced drastic climatic oscillations, including periods of extensive glaciation. These changes had a severe impact on both the !ora and fauna causing widespread extinction and range shifts with some taxa retreating to refugia in the Mediterranean Basin. Here we provide evidence for this hypothesis using foss...

The location of Israel at the junction of three continents leads to a unique fauna of both Palearctic and Afrotropical zoogeographic origins. Following systematic revisions over the past sixty years and the discovery of new species, the only available key to the pseudoscorpions of Israel has become outdated. We provide here an up-to-date checklist...
Article
Pseudoscorpions have a sparse fossil record although they are among the oldest terrestrial lineages with origins extending to the Devonian (ca. 390 Ma). Amongst the 25 extant families of pseudoscorpions, only 14 are known from fossils, most of which are preserved in European ambers from the Eocene. Fossil pseudoscorpions from the Cretaceous of Euro...
Article
Despite the recent advent of molecular data to assess the phylogeny of many invertebrate groups, the systematics of the pseudoscorpion family Chernetidae is unresolved, even though it comprises a quarter of the world’s generic pseudoscorpion diversity. We derive a preliminary molecular phylogeny of chernetids to assess subfamilial and generic monop...
Article
Full-text available
Advanced sequencing technologies have expedited resolving higher-level arthropod relationships. Yet, dark branches persist, principally among groups occurring in cryptic habitats. Among chelicerates, Solifugae (“camel spiders”) is the last order lacking a higher-level phylogeny and thus, historically characterized as “neglected [arachnid] cousins”....

South Korea is a country with more than 1000 caves that support a high diversity of invertebrate species. Here we review the pseudoscorpion genus Spelaeochthonius Morikawa, 1954 (family Pseudotyrannochthoniidae) that is exclusive to caves in Japan and South Korea and reinstated here as a valid taxon. Based on recent field collections, three species...
Article
The pseudotyrannochthoniid genus Centrochthonius Beier, 1931 is one of the rarest and most poorly understood pseudoscorpion genera in the world. Only a handful of specimens are presently known, all from high-altitude habitats in China, Kyrgyzstan and Nepal. The inaccessibility of specimens has resulted in major taxonomic difficulties such as a poor...
Article
The tropical forests of the Western Ghats (WG) of India are considered ‘refugia’ harbouring highly diverse and endemic taxa but these refugia are under immense anthropogenic pressure. Most phylogenetic studies have explained diversity patterns across the WG using vertebrates, however, the processes impacting the highly endemic invertebrate fauna ar...
Article
Full-text available
Pseudoscorpions are an ancient and globally distributed lineage of arachnids with more than 4000 species. Despite being present in virtually all terrestrial habitats, their morphology and anatomy has rarely been studied to date, which hampers homology statements both within and between other arachnid orders. All pseudoscorpions share a morphologica...
