Article Reference Introduced or established? Convergent evidence indicates imported pine wood nematode vectors occupy gaps in native distribution
Monitoring regulated quarantine plant pathogens and, when relevant, their vectors is compulsory in the European Union. Local Monochamus species (Coleoptera, Cerambycidae) vector the pine wood nematode, Bursaphelenchus xylophilus, a non-native pest already established in most of Portugal. Only 29 M. galloprovincialis individuals were trapped in Belgium in ten years (2013–2022), despite a dense coverage of pheromone-baited traps, suggesting absence or a very rare local occurrence in the country. In the northern neighbouring countries, only one single established population is known in The Netherlands and one in Denmark. A species distribution model based on pheromone-trap catches (negative and positive) of M. galloprovincialis from 4,914 traps in 29 European countries between 2008 and 2019 was developed, using the overall climate conditions and the distribution of seven pine tree species as explanatory variables. The effect of spatial scale was tested with a multi-scale approach. With a 225*225 km spatial grain, the major explanatory variables were the mean diurnal temperature range and, to a lesser extent, the presence of Pinus spp. The model predicted a low probability of presence in Belgium, the Netherlands, Great Britain and north-western Germany compared to southern Europe. Genotyping allowed to conclude that at least some of the beetles caught in Belgium originated from foreign locations. All catches were located close to entry points, suggesting introduction with imported material. The small size of most of the Belgian pine stands may also explain the absence or apparently transient status, or rareness of Monochamus spp. This study thus suggests that surveys in Belgium should privilege entry points rather than local forest stands.

Article Reference Marine Chersodromia Walker (Diptera: Hybotidae) from the Mediterranean coastline of Morocco: description of three new species with new records, supported by COI barcoding/strong
Three new species for science of Chersodromia Walker are described from the Moroccan Mediterranean coastline (C. kessabae sp. nov., C. moroccensis sp. nov. and C. estuaria sp. nov.), with the first record of Chersodromia oraria Collin, 1966 in Morocco and new distributional data are provided for Chersodromia pseudohirta Chvála, 1970. This study is based on intensive field surveys conducted by the third author along the Mediterranean coastline of Morocco between 2022 and 2024, targeting especially a variety of coastal habitats. Illustrations of the new species are given, along with COI barcodes of all species recorded. A key to the Moroccan Mediterranean species of Chersodromia is also provided.

Article Reference Brain size reduction in dogs was already established at least by the Late Neolithic of Western Europe, 5000 years ago
The timing and causes of brain size reduction in domestic dogs remain uncertain. Using endocast volume as a proxy for brain size, this study provides a first insight into long-term brain size evolution in the wolf-dog lineage. We compared endocranial volumes of 185 modern and 22 prehistoric wolves and dogs ranging from Western Europe to Australia, and spanning the Pleniglacial (35 000 yr BP) to the Late Neolithic (5000 yr BP). Our results reveal that Pleistocene so-called ‘protodogs’ show no brain size reduction compared with coeval Pleistocene wolves. Instead, we observed a slightly larger relative endocranial volume in the 35 000-year-old 'protodog' from Goyet, which could suggest increased behavioural flexibility in the presence of humans. In contrast, Late Neolithic dogs show a drastic brain size reduction (46\%) with endocranial volumes comparable to modern small terrier and toy breeds. We speculate that the anxious and wary temperaments of these Late Neolithic dogs, induced by the brain tissue reorganization associated with such a size reduction, could have served an alerting purpose, among the many other potential roles dogs could have played within these Late Neolithic socio-ecosystems.

Article Reference The thermal properties of the Mercia Mudstone Group
The Mercia Mudstone Group (MMG) crops out extensively across England and Wales and its thermal properties are required for the design of infrastructure such as ground source heating and cooling schemes and electrical cable conduits. Data from the literature and new data from a borehole core have been compiled to generate an updated range of thermal conductivities related to rock type and the lithostratigraphy. These indicate a total range in saturated vertical thermal conductivity of 1.67– 3.24 W m−1 K−1, comprising 1.67–2.81 W m−1 K−1 for mudstones, 2.12–2.41 W m−1 K−1 for siltstones and 2.3–3.24 W m−1 K−1 for sandstones. These data are all from measurements on samples and there will be uncertainty when considering the thermal properties of the rock mass owing to micro- and macrostructural features. Geometric mean modelling of thermal conductivity based on mineralogy has overestimated the thermal conductivity. Correction factors for the modelled thermal conductivities have been calculated to allow a first estimate of MMG thermal conductivities when only mineralogical data are available. Measured thermal diffusivities from the borehole core were in the range of 0.63–3.07 × 10−6 m2 s−1 and are the first measured thermal diffusivities to be reported for the MMG.

Article Reference Morphological evidence for early dog domestication in the European Pleistocene: New evidence from a randomization approach to group differences
The antiquity of the wolf/dog domestication has been recently pushed back in time from the Late Upper Paleolithic (~14,000 years ago) to the Early Upper Paleolithic (EUP; ~36,000 years ago). Some authors questioned this early dog domestication claiming that the putative (EUP) Paleolithic dogs fall within the morphological range of recent wolves. In this study, we reanalyzed a data set of large canid skulls using unbalanced‐ and balanced‐randomized discriminant analyses to assess whether the putative Paleolithic dogs are morphologically unique or whether they represent a subsample of the wolf morpho‐population. We evaluated morphological differences between 96 specimens of the 4 a priori reference groups (8 putative Paleolithic dogs, 41 recent northern dogs, 7 Pleistocene wolves, and 40 recent northern wolves) using discriminant analysis based on 5 ln‐transformed raw and allometrically size‐adjusted cranial measurements. Putative Paleolithic dogs are classified with high accuracies (87.5 and 100.0%, cross‐validated) and randomization experiment suggests that these classification rates cannot be exclusively explained by the small and uneven sample sizes of reference groups. It indicates that putative Upper Paleolithic dogs may represent a discrete canid group with morphological signs of domestication (a relatively shorter skull and wider palate and braincase) that distinguish them from sympatric Pleistocene wolves. The present results add evidence to the view that these specimens could represent incipient Paleolithic dogs that were involved in daily activities of European Upper Paleolithic forager groups.
