Article Reference AN ANNOTATED CHECKLIST OF THE OLIGO-MIOCENE CEPHALOPODS OF THE MALTESE ISLANDS
A systematic checklist of cephalopod fossils (Phylum Mollusca: Class Cephalopoda) recorded from the Oligo-Miocene sedimentary sequence of the Maltese archipelago is given. It consists of species of the nautilid genera Aturia and Eutrephoceras, next to calcified parts of the nautilid animal’s upper jaw placed under the parataxon Rhyncolites, and of sepiid and spirulid coleoid genera Sepia (Sepiida) and Spirulirostra (Spirulirostrida). Cephalopod fossils from the Maltese archipelago, in particular abundant limonitic or phosphoritic specimens of Aturia and Sepia, have been recorded in scientific literature since the middle part of the 19th Century. The identification of several species of Sepia is hampered by lost type material and taphonomic distortion or loss of diagnostic traits.

Article Reference An endemic species flock of Candonidae Kaufmann, 1900 (Crustacea, Ostracoda) from wells in Benin (West Africa), with the description of a new subfamily, a new genus and five new species
Between 2015 and 2022, over 200 wells were sampled in four catchment areas of Benin, using both Cvetkov plankton nets (funnel 200 μm mesh size, 150 μm below valve) and baited traps. As artificial wells serve as ecotones (interfaces between surface and groundwater ecosystems), the ostracod fauna is mostly represented by two families; Cyprididae (mainly epigeic) and Candonidae (hypogeic). Here, we describe a new subfamily of Candonidae from the wells in Benin, the Benincandoninae subfam. nov. Hotèkpo & Martens, represented by one genus, Benincandona gen. nov. Hotèkpo & Martens. we found 35 species belonging to this evolutionary radiation, of which we describe five new species: Benincandona martini gen. et spec. nov. Hotèkpo & Martens, B. ibikounlei gen. et spec. nov. Hotèkpo & Martens, B. sakitii gen. et spec. nov. Hotèkpo & Martens, B. cebios gen. et spec. nov. Hotèkpo & Martens and B. trapezoides gen. et spec. nov. Hotèkpo & Martens. The new subfamily and genus are characterised by a unique combination of characters, such as a seven-segmented antennula and a caudal ramus with a fully developed ramus, a single apical (anterior) claw and three short setae. Species within the genus can be distinguished by their carapace and hemipenis morphology, together with some limb characteristics. whereas extensive subterranean candonid radiations have previously been reported from Europe, North and Central America and Northwest Australia (Pilbara), this is the first time such a vast radiation of subterranean candonids is reported from (west) Africa.

Article Reference An ichthyological borderland: The fishfauna of Nyungwe National Park and surroundings (Rwanda, East Africa)
Nyungwe National Park (NP) is a mountainous region situated in the southwestern part of Rwanda on Congo-Nile watershed. In spite of the high biodiversity in pri- mates, birds and plants, no fish were reported to occur in the park, probably because of the cold temperatures of the rivers. An expedition in 2022 examined the fish diver- sity within the Nyungwe NP and its buffer zones. Additional sampling was performed in the main river draining the park into Lake Kivu: the Kamiranzovu. Three hundred and twenty specimens belonging to 13 species were collected. Specimens were col- lected only in the western part of the park, draining towards the Congo basin. The diversity within the park proper was limited to two putative species within the com- plex of Amphilius cf. kivuensis, which were caught on either side of the Kivu–Rusizi watershed. In contrast, a higher fish diversity, including one clariid species and two species of Enteromius, was observed in the rivers at a lower altitude of the buffer zone. However, the highest species diversity was found near the mouth of Kamiran- zovu River, including 11 species, of which 4 were non-native: the guppy Poecilia reti- culata, Astatotilapia burtoni, the blue-spotted tilapia Oreochromis leucosticus and the Egyptian mouth-brooder Pseudocrenilabrus multicolor.

Article Reference chemical/x-mdl-sdfile An integrated high-resolution bathymetric model for the Danube Delta system
Acting as a buffer between the Danube and the Black Sea, the Danube Delta plays an important role in regulating the hydro-biochemical flows of this land-sea continuum. Despite its importance, very few studies have focused on the impact of the Danube Delta on the different fluxes between the Danube and the Black Sea. One of the first step to characterize this land-sea continuum is to describe the bathymetry of the Delta. However, there is no complete, easily accessible bathymetric data on all three branches of the Delta to support hydrodynamic, biogeochemical or ecological studies. In this study, we aim to fill this gap by combining 4 different datasets, three in the river and one for the riverbanks, each varying in density and spatial distribution, to create a high-resolution bathymetry dataset. The bathymetric data was interpolated on a hybrid curvilinear-unstructured mesh with an anisotropic Inverse Distance Weighting (IDW) interpolation method. The resulting product offers resolutions ranging from 2 m in a connection zone to 100 m in one of the straight unidirectional channel. Cross validation of the dataset underlined the importance of the data source spatial pattern, with average Root Mean Square Error (RRMSE) of 0.55 %, 6.3 % and 27.6%, for river segments covered by the densest to the coarsest dataset. These error rates are comparable to those observed in bathymetry interpolation in rivers with similar source datasets. The bathymetry presented in this study is the first unique, high-resolution, comprehensive and easily accessible bathymetric model covering all three branches of the Danube Delta. The dataset is available at https://doi.org/10.5281/zenodo.14055741.
