Article Reference Recent Belgian records of the hornet rove-beetle Quedius (Velleius) dilatatus (Fabricius, 1787) (Coleoptera: Staphylinidae)
We report recent records of the rove beetle Quedius dilatatus (Fabricius, 1787) in Belgium. This beetle lives in nests of the European hornet Vespa crabro L., 1758 (Hymenoptera: Vespidae) and possibly profits of the recent expansion of its host. However, it seems its recent distribution is also linked to the use of recently more often used trap types, baited with an ethanol, water, glycerol and acetic acid mixture, or baited with red wine with ethanol or even white or red wine vinegar, mimicking the smell of freshly decaying wood. These methods of trapping are discussed in this paper.

Article Reference The extraordinary diversity of ants (Hymenoptera: Formicidae) of leaf litter in the Yangambi Biosphere Reserve, Tshopo, Democratic Republic of the Congo
The Democratic Republic of the Congo has the highest diversity of ant species in the Afrotropical region, even though it remains largely understudied in the modern era. The aim of this study is to report on an inventory of the litter ants from the Yangambi Biosphere Reserve in the Tshopo Province, north of the Congo River. Three habitats (fallow, secondary forest and primary forest) were sampled at six localities. A total of 190 ant species belonging to 50 genera and 8 subfamilies, have been recorded in the Yangambi biosphere region. Besides, 96 species were added to Tshopo Province, bringing the total to 306, a 44% increase; and we added 55 species to the already diverse Democratic Republic of the Congo, raising the total record to 791 species, a 7% increase. At least 10% of the collected species are new to science.

Article Reference Hydrodynamic alterations induced by floating solar structures co-located with an offshore wind farm
Floating photovoltaic installations (FPV) are among the promising emerging marine renewable energy systems contributing to future global energy transition strategies. FPVs can be integrated within existing offshore wind farms, contributing to more efficient use of marine space. This complementarity has gained increasing attention as a sustainable approach to enhance green energy production while reducing offshore grid infrastructure costs, particularly in the North Sea. This study presents a first assessment to quantify the mid- and far-field hydrodynamic effects of FPVs (elevated design) deployed within an existing offshore wind farm (OWF) in the Belgian part of the North Sea. A subgrid-scale parameterization was adopted into the 3D hydrodynamic model COHERENS to assess impacts on four key hydrodynamic metrics: surface irradiance reduction due to shading, changes in current velocity fields, turbulent kinetic energy production, and variations in current-induced bottom shear stress. Four scenarios were compared: a baseline without structures, a scenario with only offshore wind turbines and two combined wind and photovoltaic configurations (sparse and dense). At farm scale, simulations showed small effects of FPV shading on sea surface temperature (< 0.1°C), but significant reductions in current speed, increased turbulent kinetic energy mainly beneath the floaters, and a noticeable impact on bottom shear stress. This hydrodynamic modeling study constitutes a first step toward a comprehensive environmental impact assessment of FPVs, particularly in relation to their biogeochemical effects on the water column and benthic habitats. The findings provide valuable insights to support sustainable marine spatial planning, environmental assessments, and industrial design strategies in the North Sea and beyond.

Article Reference A new bird-like dinosaur from the Upper Cretaceous of Mongolia with extremely robust hands supports niche partitioning among velociraptorines
Dromaeosauridae is a clade of bird-like theropod dinosaurs including, among others, the genera Deinonychus and Velociraptor, and characterised by a specialised second toe bearing an enlarged and falciform ungual. Here, we describe an exquisitely-preserved velociraptorine dromaeosaurid from the Upper Cretaceous Djadokhta Formation of Mongolia, and refer it to the new species Shri rapax. This dromaeosaurid is diagnosed by a peculiar combination of vertebral and pelvic features and by an exceptionally robust hand with a very stout pollex bearing the ungual proportionally larger than in any other dromaeosaurid. Combined with cranial adaptations which could support a bite more powerful than in other velociraptorines, the enlarged unguals in both Shri species suggest ecological partitioning in prey preference among the sympatric Djadokhtan dromaeosaurids.

Article Reference The record of cricetid rodents across the Eocene–Oligocene transition in Transylvania, Romania: implications for the “Grande Coupure” at European scale
A number of localities in Transylvania (Romania) have yielded vertebrate microfossil remains. Two localities have been stratigraphically and biochronologically dated to the late Eocene: i.e., Treznea and Bociu. The remaining three localities are dated to the early Oligocene: Mera, Cetățuie, and Suceag. The study of cricetid rodents corroborates the presence of this family in Eastern Europe during the late Eocene, as evidenced by the species Witenia sp., Bustrania cf. B. dissimile , and Eocricetodon cf. Eo. meridionalis. The cricetids identified in the sites of the early Oligocene age show a complete turnover and a notable increase in species richness following the Eocene/Oligocene boundary, with: Eucricetodon aff. Eu. huerzeleri, Tenuicricetodon arcemis gen. et sp. nov., Pseudocricetodon cf. Ps. montalbanensis, Paracricetodon cf. Pa. walgeri, Paracricetodon kavakderensis, Paracricetodon aff. Pa. stojonovici, and Paracricetodon wentgesi. In the context of the wider biogeographic history of Europe, these new discoveries indicate that Cricetidae arrived in Europe during at least two successive migrations from Asia in the late Eocene and earliest Oligocene. These migrations may have occurred via two different migration pathways through the north and south of Europe. In a second phase, Cricetidae arriving by the northern passway spread throughout Europe, whereas Cricetidae that arrived by the southern passway remained restricted to the central and southeastern Europe. The observations made on the Cricetidae allow for the proposal of a new, more general, scenario for the Eocene–Oligocene transition on a European scale, which is more complex than the “Grande Coupure” sensu stricto as initially proposed by Stehlin in 1909.
