A GIS-based methodology for creating 3D geological models in sedimentary environment: application to the subcrop of Brussels
-
In order to meet the requirements established by the European Directive (2006/118/EC) on the groundwater protection, the Geological Survey of Belgium (GSB) has started a new Geographic Information System (GIS) project called Hydrobrux. The aim is to create a thorough three-dimensional geological model of the subcrop of Brussels. The latter will be used to produce a hydrogeological model of the Brussels Formation aquifer composed of sands and covering 126 km2 in the eastern part of the Brussels-Capital Region and subsequent deeper aquifers (Palaeocene and Upper Cretaceous). The GIS 3D model is built by superposition of interpolated surfaces, which represent the top surface of each modelled geological layers. Eleven top surfaces are generated independently and are based on the interpolation of 5169 points. This high density of information is provided by 2426 boreholes, water wells, outcrops, cone penetration tests (CPT) and other sources of stratigraphic data that were collected and structured in a relational database under Microsoft Access. The data were exported to ArcGIS for the geostatistics (2D mapping) and validation parts and subsequently to ArcScene for the construction and the visualisation of the 3D model.

A global approach for natural history museum collections
-
Integration of the world’s natural history collections can provide a resource for decision-makers Over the past three centuries, people have collected objects and specimens and placed them in natural history museums throughout the world. Taken as a whole, this global collection is the physical basis for our understanding of the natural world and our place in it, an unparalleled source of information that is directly relevant to issues as diverse as wildlife conservation, climate change, pandemic preparedness, food security, invasive species, rare minerals, and the bioeconomy (1). Strategic coordination and use of the global collection has the potential to focus future collecting and guide decisions that are relevant to the future of humanity and biodiversity. To begin to map the aggregate holdings of the global collection, we describe here a simple and fast method to assess the contents of any natural history museum, and report results based on our assessment of 73 of the world’s largest natural history museums and herbaria from 28 countries.

A global database of ant species abundances
-
What forces structure ecological assemblages? A key limitation to general insights about assemblage structure is the availability of data that are collected at a small spatial grain (local assemblages) and a large spatial extent (global coverage). Here, we present published and unpublished data from 51,388 ant abundance and occurrence records of more than 2693 species and 7953 morphospecies from local assemblages collected at 4212 locations around the world. Ants were selected because they are diverse and abundant globally, comprise a large fraction of animal biomass in most terrestrial communities, and are key contributors to a range of ecosystem functions. Data were collected between 1949 and 2014, and include, for each geo-referenced sampling site, both the identity of the ants collected and details of sampling design, habitat type and degree of disturbance. The aim of compiling this dataset was to provide comprehensive species abundance data in order to test relationships between assemblage structure and environmental and biogeographic factors. Data were collected using a variety of standardised methods, such as pitfall and Winkler traps, and will be valuable for studies investigating large-scale forces structuring local assemblages. Understanding such relationships is particularly critical under current rates of global change. We encourage authors holding additional data on systematically collected ant assemblages, especially those in dry and cold, and remote areas, to contact us and contribute their data to this growing dataset.

A gymnodont fish jaw with remarkable molariform teeth from the early Eocene of Gujarat, India (Teleostei, Tetraodontiformes)
-
The lower jaw of a gymnodont fish collected from the lower Eocene Cambay Shale Formation in Gujarat Province, western India, has fused dentaries without a beak and a remarkable series of teeth that are unique among all known fossil and living Tetraodontiformes. The teeth are molariform, with raised spokes radiating inward from the emarginated peripheral edge of the crown. Tooth development is intraosseous, with new teeth developing in spongy bone before they erupt and attach to the dentary by pedicels. Although many of the 110 tooth loci in the fossil have lost their teeth, in life the teeth would have grown to fit tightly together to form a broad and continuous crushing surface. The estimated age of the Cambay Shale vertebrate fauna is ca. 54.5 Ma, making the jaw the second oldest confirmed gymnodont fossil. Preliminary comparisons with extant taxa of gymnodonts with fused dentaries (e.g., Diodon, Chilomycterus, and Mola) show detailed similarities in jaw structure, but further study of the dentition is needed to better understand the evolutionary position of the new fossil. We describe the new gymnodont as yAvitoplectus molaris, gen. et sp. nov., in yAvitoplectidae, fam. nov., and place the family as incertae sedis within Gymnodontes.

A high-resolution DEM for the Top-Palaeogene surface of the Belgian Continental Shelf
-
A 1:250,000 scale map of the surface of the Top-Palaeogene for the Belgian Continental Shelf was created based on extensive analyses of older and recent geological and geophysical datasets. The Top-Palaeogene surface is an important polygenetic unconformity that truncates older strata of the Palaeogene and to a smaller extent some of Neogene age from the overlying Quaternary deposits. As such it represents the base of the latter. The represented surface has been diachronously shaped and reworked through Late Quaternary times by different geological processes (e.g. fluvial, marine, estuarine, periglacial). Additionally, the offshore surface has been attached to the landward Top-Palaeogene surface and was transformed into a uniform 3D surface allowing new and better interpretations to be used in fundamental and applied research underpinning both scientific purposes (e.g. geology, archaeology, palaeogeography), and commercial applications (e.g. wind farms, aggregate extraction, dredging).
