Article Reference Ancient DNA suggests modern wolves trace their origin to a Late Pleistocene expansion from Beringia
Grey wolves (Canis lupus) are one of the few large terrestrial carnivores that have maintained a wide geographical distribution across the Northern Hemisphere throughout the Pleistocene and Holocene. Recent genetic studies have suggested that, despite this continuous presence, major demographic changes occurred in wolf populations between the Late Pleistocene and early Holocene, and that extant wolves trace their ancestry to a single Late Pleistocene population. Both the geographical origin of this ancestral population and how it became widespread remain unknown. Here, we used a spatially and temporally explicit modelling framework to analyse a data set of 90 modern and 45 ancient mitochondrial wolf genomes from across the Northern Hemisphere, spanning the last 50,000 years. Our results suggest that contemporary wolf populations trace their ancestry to an expansion from Beringia at the end of the Last Glacial Maximum, and that this process was most likely driven by Late Pleistocene ecological fluctuations that occurred across the Northern Hemisphere. This study provides direct ancient genetic evidence that long‐range migration has played an important role in the population history of a large carnivore, and provides insight into how wolves survived the wave of megafaunal extinctions at the end of the last glaciation. Moreover, because Late Pleistocene grey wolves were the likely source from which all modern dogs trace their origins, the demographic history described in this study has fundamental implications for understanding the geographical origin of the dog.

Article Reference Ancient West African foragers in the context of African population history
Our knowledge of ancient human population structure in sub-Saharan Africa, particularly prior to the advent of food production, remains limited. Here we report genome-wide DNA data from four children—two of whom were buried approximately 8,000 years ago and two 3,000 years ago—from Shum Laka (Cameroon), one of the earliest known archaeological sites within the probable homeland of the Bantu language group1–11. One individual carried the deeply divergent Y chromosome haplogroup A00, which today is found almost exclusively in the same region12,13. However, the genome-wide ancestry profiles of all four individuals are most similar to those of present-day hunter-gatherers from western Central Africa, which implies that populations in western Cameroon today—as well as speakers of Bantu languages from across the continent—are not descended substantially from the population represented by these four people. We infer an Africa-wide phylogeny that features widespread admixture and three prominent radiations, including one that gave rise to at least four major lineages deep in the history of modern humans.

Book Reference 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.

Article Reference Octet Stream Ant biodiversity conservation in Belgian calcareous grasslands: Active management is vital
A list of ant species collected in eight calcareous grasslands in the Viroin valley (Viroinval, Belgium) is presented. Thirty species were identified, including Temnothorax albipennis, for the first time recorded in Belgium. Ant community composition and chorology of some ant species are discussed. Recommendations on how to use ant community composition and nest densities of several ant species to evaluate management in calcareous grasslands are given. It appears that in locations with encroachment of tall grasses (especially Brachypodium pinnatum) and spontaneous afforestation, due to a complete lack of or to inadequate management, most of the often rare xerophilic ant species are replaced by mesophilic, rather common species.

Article Reference Ant communities in recently restored dune grassland ecosystems in Belgium (Hymenoptera: Formicidae)
In the period 2000-2001 nature restoration projects drastically reshaped the Nature Reserve in Lombardsijde near the Ijzer Estuary in Flanders, Belgium. Dikes were constructed and new dune grasslands were installed. Seven years after the restoration the ant fauna of these newly created sites was compared with reference sites from foredunes, dune grasslands and grey dunes. Ants were collected with pitfall traps in 10 sample sites during 4 years. Our results showed that after 7 even 10 years of nature restoration, the ant fauna in the newly created sites still differs substantially from those of the reference sites. However, typical dune grassland ant species like Myrmica specioides, Myrmica sabuleti and Lasius psammophilus were already present at the newly created sites. Our data also suggests that it takes a longer period for characteristic dune grassland ants species to colonize and settle in these new environments than for other invertebrate groups like spiders and carabid beetles that were also collected and studied during the same project and reported before.
