GEASI : Geodesic-based earliest activation sites identification in cardiac models

Grandits, Thomas ; Effland, Alexander ; Pock, Thomas ; Krause, Rolf ; Plank, Gernot ; Pezzuto, Simone

In: International journal for numerical methods in biomedical engineering, 2021, vol. 37, no. 8, p. 30

The identification of the initial ventricular activation sequence is a critical step for the correct personalization of patient- specific cardiac models. In healthy conditions, the Purkinje network is the main source of the electrical activation, but under pathological conditions the so-called earliest activation sites (EASs) are possibly sparser and more localized. Yet, their number, location...

New species, revision, and phylogeny of Ronzotherium Aymard, 1854 (Perissodactyla, Rhinocerotidae)

Tissier, Jérémy ; Antoine, Pierre-Olivier ; Becker, Damien

In: European Journal of Taxonomy, 2021, vol. 753, p. 1-80

Ronzotherium is one of the earliest Rhinocerotidae in Europe, which first appeared just after the Eocene/Oligocene transition (Grande Coupure), and became extinct at the end of the Oligocene. It is a large-sized rhinocerotid, with a special position in the phylogeny of this group, as being one of the earliest-branching true Rhinocerotidae. However, its intra-generic systematics has never been...

A transdisciplinary analysis of COVID-19 in Italy : the most affected country in Europe

Ortenzi, Flaminia ; Albanese, Emiliano ; Fadda, Marta

In: International journal of environmental research and public health, 2020, vol. 17, no. 24, p. 12 p

As of 27 March 2020, 199 countries and territories and one international conveyance are affected by the COVID-19 pandemic. As of the same date, Italy represents the third country worldwide in total number of cases and the first one in total number of deaths. The purpose of this study is to analyse the Italian case and identify key problem questions and lessons learned from the Italian...

A new species of the large-headed coastal marine turtle Solnhofia (Testudinata, Thalassochelydia) from the Late Jurassic of NW Switzerland

Anquetin, Jérémy ; Püntener, Christian

In: PeerJ, 2020, vol. 8, p. e9931

Background: The large-headed turtle Solnhofia parsonsi is known by a handful of specimens from the Late Jurassic of Germany and Switzerland (maybe also France). Solnhofia parsonsi is traditionally regarded as a “eurysternid” Thalassochelydia, a group of small to medium sized, mostly lagoonal or marginal turtles found almost exclusively in the Late Jurassic of Europe. More recently,...

3D model related to the publication: A new species of the large-headed coastal marine turtle Solnhofia (Testudinata, Thalassochelydia) from the Late Jurassic of NW Switzerland

Anquetin, Jérémy ; Püntener, Christian

In: MorphoMuseuM, 2020, vol. 6, no. 4, p. e118

This contribution contains the 3D surface model of the holotype cranium of the Late Jurassic thalassochelydian turtle Solnhofia brachyrhyncha described and figured in the publication of Anquetin and Püntener (2020).

Assessing the risks of non-target feeding by the accidentally introduced ragweed leaf beetle, Ophraella communa, to native European plant species

Augustinus, Benno Andreas ; Gentili, Rodolfo ; Horvath, David ; Naderi, Ruhollah ; Sun, Yan ; Tournet, Anne-Marth Truce Eleonoor ; Schaffner, Urs ; Müller-Schärer, Heinz

In: Biological Control, 2020, vol. 150, p. 104356

In 2013, the North American oligophagous leaf beetle, Ophraella communa LeSage (Coleoptera: Chrysomelidae), was found in Europe for the first time. Recent studies in Northern Italy and Southern Switzerland record extensive defoliation by O. communa on its preferred host, common ragweed, Ambrosia artemisiifolia L. (Asteraceae, Tribe Heliantheae), and reductions in its flowering and seeding. In...

New material of Epiaceratherium and a new species of Mesaceratherium clear up the phylogeny of early Rhinocerotidae (Perissodactyla)

Tissier, Jérémy ; Antoine, Pierre-Olivier ; Becker, Damien

In: Royal Society Open Science, 2020, vol. 7, no. 7, p. 200633

Reduction of the anterior dentition (i.e. incisors and canines) is a major adaptative trait of the Rhinocerotidae among Perissodactyla. However, the corresponding evolutionary sequence was lacking a robust phylogenetic frame to support it thus far. Here, we describe a new Oligocene species of Rhinocerotinae, Mesaceratherium sp. nov. from the Swiss locality of Bumbach (MP25 reference level)....

Impossibility results on stability of phylogenetic consensus methods

Delucchi, Emanuele ; Hoessly, Linard ; Paolini, Giovanni

In: Systematic Biology, 2020, vol. 69, no. 3, p. 557–565

We answer two questions raised by Bryant, Francis, and Steel in their work on consensus methods in phylogenetics. Consensus methods apply to every practical instance where it is desired to aggregate a set of given phylogenetic trees (say, gene evolution trees) into a resulting, “consensus” tree (say, a species tree). Various stability criteria have been explored in this context, seeking...

The last surviving Thalassochelydia — A new turtle cranium from the Early Cretaceous of the Purbeck Group (Dorset, UK)

Anquetin, Jérémy ; André, Charlotte

In: PaleorXiv, 2020, p. 7pa5c

Background. The mostly Berriasian (Early Cretaceous) Purbeck Group of southern England has produced a rich turtle fauna dominated by the freshwater paracryptodires Pleurosternon bullockii and Dorsetochelys typocardium. Each of these species is known by numerous relatively complete shells and by a single cranium. The two other turtles found in the Purbeck Group (Hylaeochelys belli, a species of...
