Article Reference 33 million year old Myotis (Chiroptera, Vespertilionidae) and the rapid global radiation of modern bats
The bat genus Myotis is represented by 120+ living species and 40+ extinct species and is found on every continent except Antarctica. The time of divergence of Myotis has been contentious as has the time and place of origin of its encompassing group the Vespertilionidae, the most diverse (450+ species) and widely distributed extant bat family. Fossil Myotis species are common, especially in Europe, beginning in the Miocene but earlier records are poor. Recent study of new specimens from the Belgian early Oligocene locality of Boutersem reveals the presence of a relatively large vespertilionid. Morphological comparison and phylogenetic analysis confirms that the new, large form can be confidently assigned to the genus Myotis, making this record the earliest known for that taxon and extending the temporal range of this extant genus to over 33 million years. This suggests that previously published molecular divergence dates for crown myotines (Myotis) are too young by at least 7 million years. Additionally, examination of first fossil appearance data of 1,011 extant placental mammal genera indicates that only 13 first occurred in the middle to late Paleogene (48 to 33 million years ago) and of these, six represent bats, including Myotis. Paleogene members of both major suborders of Chiroptera (Yangochiroptera and Yinpterochiroptera) include extant genera indicating early establishment of successful and long-term adaptive strategies as bats underwent an explosive radiation near the beginning of the Early Eocene Climatic Optimum in the Old World. A second bat adaptive radiation in the New World began coincident with the Mid-Miocene Climatic Optimum.

Article Reference A (very) brief vademecum on biological nomenclature
This editorial is aimed at explaining why the editors of Hydrobiologia are so concerned with biological nomenclature and why we ask our authors the utmost precision when referring to species in their papers. In particular, the Instructions for Authors of the journal specify that “When a species name is used for the first time in an article, it should be stated in full, and the name of its describer should also be given” (https://www.springer.com/journal/10750/submission-guidelines?IFA#Instructions%20for%20Authors_Scientific%20style). In the next lines, we want to show that this is not just an old fashion formalism, but a necessity to correctly and univocally identify the biological subjects that are the basis of the research published in this journal. Moreover, Hydrobiologia is a generalist journal giving voice to research embedded in a wide ecological and evolutionary context, carried out in any kind of aquatic ecosystem, and considering all their biological entities from small viruses onwards to large whales! Thus, the work of a, for example, fish biologist, should be readable for a botanist and vice versa. This achievement can be reached by avoiding as much as possible the jargon typical of each discipline (as the so called “common names” can be considered) and allowing the unequivocal identification of the targeted biological entities.

Article Reference application/x-troff-ms A 3D numerical baroclinic application of the COHERENS model in the Gulf of Guinea, West Africa
In this study, we have developed a three-dimensional (3D) numerical model based on COHERENS modelling system to describe the tidal, wind-driven and thermohaline induced hydrodynamic regime in the coastal water of the Gulf of Guinea. The model is validated with respect to water levels, sea currents, temperature and salinity during 2017. Validation for astronomical tides showed that the model is able to simulate observed tidal elevation and phases for both diurnal and semi-diurnal principal constituents with a consistent level of agreement at measurement station. A statistical analysis of the results showed that the correlation coefficient and skill index between the modelled and observed tidal elevations are both above 0.96 with an average RMSE of 9 cm. The atmospheric contribution to water levels was also validated. In this case, we observe a good agreement between modelled and measured water levels with a correlation coefficient of 0.75 and an average RMSE of 1.23 cm. The validation of spatial distribution and vertical evolution of zonal current, salinity and temperature also indicated a high model accuracy for these variables. Overall, we show that our model of the Gulf of Guinea leads to highly accurate simulations, providing a basis for further fundamental and applied research studies in the area.

Article Reference A 365-Million-Year-Old Freshwater Community Reveals Morphological and Ecological Stasis in Branchiopod Crustaceans
Branchiopod crustaceans are represented by fairy, tadpole, and clam shrimps (Anostraca, Notostraca, Laevicaudata, Spinicaudata), which typically inhabit temporary freshwater bodies, and water fleas (Cladoceromorpha), which live in all kinds of freshwater and occasionally marine environments. The earliest branchiopods occur in the Cambrian, where they are represented by complete body fossils from Sweden such as Rehbachiella kinnekullensis and isolated mandibles preserved as small carbonaceous fossils from Canada. The earliest known continental branchiopods are associated with hot spring environments represented by the Early Devonian Rhynie Chert of Scotland (410 million years ago) and include possible stem-group or crown-group Anostraca, Notostraca, and clam shrimps or Cladoceromorpha, which differ morphologically from their modern counterparts. Here we report the discovery of an ephemeral pool branchiopod community from the 365-million-year-old Strud locality of Belgium. It is characterized by new anostracans and spinicaudatans, closely resembling extant species, and the earliest notostracan, Strudops goldenbergi. These branchiopods released resting eggs into the sediment in a manner similar to their modern representatives. We infer that this reproductive strategy was critical to overcoming environmental constraints such as seasonal desiccation imposed by living on land. The pioneer colonization of ephemeral freshwater pools by branchiopods in the Devonian was followed by remarkable ecological and morphological stasis that persists to the present day.
