Importance of the Postcranial Skeleton in Eusuchian Phylogeny: Reassessing the Systematics of Allodaposuchid Crocodylians
RUC. Repositorio da Universidade da Coruña
- Blanco, Alejandro
[Abstract] Our current knowledge on the crocodyliform evolution is strongly biased towards the skull morphology, and the postcranial skeleton is usually neglected in many taxonomic descriptions. However, it is logical to expect that it can contribute with its own phylogenetic signal. In this paper, the changes in the tree topology caused by the addition of the postcranial information are analysed for the family Allodaposuchidae, the most representative eusuchians in the latest Cretaceous of Europe. At present, different phylogenetic hypotheses have been proposed for this group without reaching a consensus. The results of this paper evidence a shift in the phylogenetic position when the postcranium is included in the dataset, pointing to a relevant phylogenetic signal in the postcranial elements. Finally, the phylogenetic relationships of allodaposuchids within Eusuchia are reassessed; and the internal relationships within Allodaposuchidae are also reconsidered after an exhaustive revision of the morphological data. New and improved diagnoses for each species are here provided., This work was supported by postdoctoral grants funded by the program “Axudas á etapa postdoutoral da Xunta de Galicia 2017 – Modalidade A” (ED481B 2017/027) (https://www.xunta.gal/) and the program “Ayudas Juan de la Cierva – Formación 2019” (FJC2019-042583-I) (https://www.ciencia.gob.es/).

The taxonomic position of Annandale's rat, Rattus annandalei (Bonhote, 1903), has been uncertain given its mix of Rattus-like and Sundamys-like morphological features. Annandale's rat and all described species in Sundamys (the lowland S. muelleri, and the montane S. maxi and S. infraluteus) are endemic to Sundaland, a center of diversification and endemism for their tribe, the Rattini. Using mitochondrial genomes and 3 nuclear markers (rag1, rbp3, ghr), we provide the 1st phylogenetic framework for Sundamys. We find that R. annandalei is nested within Sundamys, and that the 4 species likely diverged during the Pleistocene. We move R. annandalei to Sundamys and provide an emended diagnosis for Sundamys. Using geometric morphometric analyses of skulls and mandibles, we identify morphological differences between lowland and highland species of Sundamys that may be associated with adaptations to distinct diets., We are indebted to S. Morand, M. Pagès, J. Claude, and J. Michaux as the coordinators of the CERoPath project (French ANR Biodiversity, grant ANR 07 BDIV 012) and the BiodivHealthSEA project (www.biodivhealthsea.org) (French ANR CP&ES, grant ANR 11 CPEL 002).

Assessments of sperm performance are valuable tools for the analysis of sperm fertilizing potential and to understand determinants of male fertility. Hamster species constitute important animal models because they produce sperm cells in high quantities and of high quality. Sexual selection over evolutionary time in these species seems to have resulted in the largest mammalian spermatozoa, and high swimming and bioenergetic performances. Earlier studies showed that golden hamster sperm requires motility factors such as D-penicillamine, hypotaurine and epinephrine (PHE) to sustain survival over time, but it is unknown how they affect swimming kinetics or ATP levels and if other hamster species also require them. The objective of the present study was to examine the effect of PHE on spermatozoa of five hamster species (Mesocricetus auratus, Cricetulus griseus, Phodopus campbelli, P. sungorus, P. roborovskii). In sperm incubated for up to 4 h without or with PHE, we assessed motility, viability, acrosome integrity, sperm velocity and trajectory, and ATP
content. The results showed differences in the effect of PHE among species. They had a significant positive effect on the maintenance of sperm quality in M. auratus and C. griseus, whereas there was no consistent effect on spermatozoa of the Phodopus species. Differences between species may be the result of varying underlying regulatory mechanisms of sperm performance and may be important to understand how they relate to successful fertilization., This work was supported by the Spanish Ministry of Science and Innovation (projects CGL2016-80577-P and PID2019-108649GB-I00).

This site displays the diversity of Quaternary and Recent bryozoans kept in the MNCN (Museo Nacional de Ciencias Naturales, National Museum of Natural Sciences of Madrid). It has been created thanks to Synthesys Virtual Access (VA) Call 2, 2021, for the international project Bryozoa Identification Tool (BIT) for Quaternary and Recent Mediterranean and North Atlantic Bryozoans. There are SEM images of the most represenative individuals and the dataset for Unix/Linus and Windows., Bryozoans are colonial animals that are widely distributed in marine benthic environments and play an important role in temperate and cold-water oceanic shelves as habitat providers. They are one of the most diverse components of intertidal and shelf environment communities. Morphologically and mineralogically diverse, bryozoans are important carbonate producers with an extensive fossil record, which makes them good indicators in environmental and paleoenvironmental research. They are helpful to address evolutionary questions, especially those dealing with the effects of climatic change on assemblages of benthic animals. Existing data, though insufficient, suggests that bryozoans can become a valuable tool in investigating present-day climate change. This project gives the opportunity to reinforce the (1) bryozoan proxy tool in climate research and it will be additionally (2) a basic resource for bryozoan identification through museum collections.
This Project aims to record, on a worldwide map with SEM photographs, all the Quaternary and Mediterranean and North Atlantic Recent bryozoan taxa kept in museums which are participants of the Synthesys Scheme in order to help with bryozoan taxonomic identification. For this, all the specimens are georeferenced and a type specimen or the best specimen of each species has been scanned under scanning electron microscope (SEM). This information is displayed through the own museums’ websites with links to their associated partners on this project (see below participants) and the GBIF Website as well. This project contributes with more than 50 bryozoan taxa not recorded on any Website. It is 3.4% of the current identified taxa from Quaternary and Mediterranean and North Atlantic recent bryozoan taxa.
Although there is already a website (https://www.bryozoa.net/) on recent bryozoan taxa, it includes SEM images of only few taxa and none are georeferenced. This is the first time that Quaternary and Recent bryozoan taxa are georeferenced on a world map and images of the different taxa are displayed. For this, some of the best world museum collections have been used., Institutions involved: NHM, Natural History Museum, London; MNHN, Museum National d'Histoire Naturelle, Paris; MNCN, Museo Nacional de Ciencias Naturales, Madrid; NHMW, Naturhistorisches Museum, Wien; Naturkunde: Museum fur Naturkunde, Berlin; NNHC-HUJI, The National Natural History Collections, The Hebrew University of Jerusalem.
It will be an important tool for species identification as the NHM-London keeps at least 215 type specimens (recent), the MNCN 219 type specimens, the MNHN 210 types, NHMW 3 recent syntype series and 3 fossil syntype lots types and Naturkunde fewer than 125 types. Most of them are not available on any other website or repository (only Naturkunde has some of them on GBIF Website, but without SEM images associated). All of the extant specimens are from Mediterranean and North Atlantic and the fossils are worldwide.
The MNCN keeps at least 5157 Quaternary and Recent bryozoan colonies to date. There are at least 395 species. Of these, 81 are holotypes and 211 paratypes belonging to 59 species. There are not less than 24% of the colonies published (1235) in 28 publications., Funded by Synthesys Virtual Access Call 2021, for the international project Bryozoa Identification Tool (BIT) for Quaternary and Recent Mediterranean and North Atlantic Bryozoans.https://creativecommons.org/licenses/by-nc-nd/4.0/, Peer reviewed

Fossil remains from the latest Messinian of Casino Basin (Tuscany, Italy) are known since the beginning of the
nineteenth century. Among the others, the mammal assemblage includes Mesopithecus pentelicus, Tapirus
arvernensis, Propotamochoerus provincialis and scarce and poorly preserved remains of a hippopotamid,
consisting of a mandibular symphysis fragment, an apical fragment of a lower canine, some isolated lower
incisors, a fragmented second upper premolar and a second lower molar. These specimens were initially
referred as Hippopotamus hipponensis and later ascribed to the new species Hippopotamus pantanellii
(recently reported as Hexaprotodon? pantanellii). However, this attribution has been disputed during the
past years. The hippopotamid remains from the Casino Basin are revised here in order to clarify their
systematic position and to infer paleobiogeographic and evolutionary patterns within the Mediterranean
fossil record of Hippopotamidae. The morphology of the remains collected from the Casino Basin more
closely resembles the African than the Asian hippopotamids’ lineage and therefore the Tuscan remains
should be more properly referred as Archaeopotamus pantanellii. The latter species probably dispersed into
Tuscany from the Iberian Peninsula where the presence of Archaeopotamus crusafonti is well documented., This work was supported by the Fundação para a Ciência e Tecnologia [2021.08458.BD] This research received support from the SYNTHESYS+ project http://www.synthesys.info/, which is financed by the European Community Research Infrastructure Action under the H2020 Integrating Activities Programme, Project number 823827 at the Museo Nacional de Ciencias Naturales (CSIC).
