Annotated Iconography of the fossil Chondrichthyan Fishes in the collection of the Royal Belgian Institute of Natural Sciences, Brussels
- This book is an extensive iconography of all types of material of Elasmobranchii (mostly teeth) of which the type specimens were found in the collections of the RBINS, in total there are 119 species. Unfortunately, 11 type series were incomplete and 17 were no longer found in the collection at all. The latter are listed in the book, but of course not depicted. It is often about Holocephali from the Paleozoic, but also about some species from the Cenozoic (e.g. Mustelus vanderhoeft, the type of which was never deposited by the author in the RBINS). All species are listed in systematic order, according to the original name, followed by the collection number. The authors have searched the original literature to the type locality and the type stratum as they were specified at the time. Since many species were defined in the19th and early20th centuries, much of that data was outdated, but they were completely revised and adapted to modern nomenclature, a titanic work. Furthermore, the original publication is given species by species and the modern systematic status is given in the notes. The photographs are of high quality and often with more views per copy so that more details are now visible than was possible in older publications. Usually one page per species is provided. It contains an extensive bibliography and the index (with both the old and modern species names) makes searching easier. Thanks to the excellent iconography, the book can also be used as a determination work, but of course only for the types in the RBINS collection.

One to host them all: genomics of the diverse bacterial endosymbionts of the spider Oedothorax gibbosus
- Bacterial endosymbionts of the groups Wolbachia , Cardinium and Rickettsiaceae are well known for their diverse effects on their arthropod hosts, ranging from mutualistic relationships to reproductive phenotypes. Here, we analysed a unique system in which the dwarf spider Oedothorax gibbosus is co-infected with up to five different endosymbionts affiliated with Wolbachia , ‘Candidatus Tisiphia’ (formerly Torix group Rickettsia ), Cardinium and Rhabdochlamydia . Using short-read genome sequencing data, we show that the endosymbionts are heterogeneously distributed among O. gibbosus populations and are frequently found co-infecting spider individuals. To study this intricate host–endosymbiont system on a genome-resolved level, we used long-read sequencing to reconstruct closed genomes of the Wolbachia , ‘Ca. Tisiphia’ and Cardinium endosymbionts. We provide insights into the ecology and evolution of the endosymbionts and shed light on the interactions with their spider host. We detected high quantities of transposable elements in all endosymbiont genomes and provide evidence that ancestors of the Cardinium , ‘Ca. Tisiphia’ and Wolbachia endosymbionts have co-infected the same hosts in the past. Our findings contribute to broadening our knowledge about endosymbionts infecting one of the largest animal phyla on Earth and show the usefulness of transposable elements as an evolutionary ‘contact-tracing’ tool.
