The implication of the new labor clauses in the USMCA on labor market and trade between the United States, Mexico and Canada

Stäuble, Mathieu ; Matile, Laurent (Dir.)

Mémoire de bachelor : Haute école de gestion de Genève, 2020 ; TDIBM 93.

The North American continent has implemented different free trade agreements throughout the years. From the Canadian-United States Free Trade Agreement (CUSFTA) reached in 1989, between Canada and the United States and quickly replaced by the North American Free Trade Agreement (NAFTA) in 1994 with the addition of Mexico to the agreement. After 26 years of existence and divergent opinions...

Cranial osteology of the early cretaceous turtle Pleurosternon bullockii (paracryptodira: pleurosternidae)

Evers, Serjoscha W. ; Rollot, Yann ; Joyce, Walter G.

In: PeerJ, 2020, vol. 8, p. e9454

Pleurosternon bullockii is a turtle from the Early Cretaceous of Europe known from numerous postcranial remains. Only one skull has so far been referred to the species. Pleurosternon bullockii belongs to a group of turtles called pleurosternids, which is thought to include several poorly known taxa from the Late Jurassic and Early Cretaceous of Europe and North America. Pleurosternids and...

An alternative interpretation of Peltochelys duchastelii as a paracryptodire

Joyce, Walter G. ; Rollot, Yann

In: Fossil Record, 2020, vol. 23, no. 1, p. 83–93

Peltochelys duchastelii is an enigmatic turtle from Early Cretaceous (middle Barremian–early Aptian) Sainte-Barbe Formation of Bernissart, Belgium. In more recent literature, there has been strong support for the trionychian affinities of this taxon, but this interpretation is less consistent with external data, in particular biogeography and temporal considerations. We provide a...

A new species of baenid turtle from the Early Cretaceous Lakota Formation of South Dakota

Joyce, Walter G. ; Rollot, Yann ; Cifelli, Richard L.

In: Fossil Record, 2020, vol. 23, no. 1, p. 1–13

Baenidae is a clade of paracryptodiran turtles known from the late Early Cretaceous to Eocene of North America. The proposed sister-group relationship of Baenidae to Pleurosternidae, a group of turtles known from sediments dated as early as the Late Jurassic, suggests a ghost lineage that crosses the early Early Cretaceous. We here document a new species of paracryptodiran turtle, Lakotemys...

Notes on the cheek region of the Late Jurassic theropod dinosaur Allosaurus

Evers, Serjoscha W. ; Foth, Christian ; Rauhut, Oliver W.M.

In: PeerJ, 2020, vol. 8, p. e8493

Allosaurus, from the Late Jurassic of North America and Europe, is a model taxon for Jurassic basal tetanuran theropod dinosaurs. It has achieved an almost iconic status due to its early discovery in the late, 19th century, and due to the abundance of material from the Morrison Formation of the western U.S.A., making Allosaurus one of the best-known theropod taxa. Despite this, various...

Global biogeographic synthesis and priority conservation regions of the relict tree family Juglandaceae

Song, Yi‐Gang ; Fragnière, Yann ; Meng, Hong‐Hu ; Li, Ying ; Bétrisey, Sébastien ; Corrales, Adriana ; Manchester, Steven ; Deng, Min ; Jasińska, Anna K. ; Văn Sâm, Hoàng ; Kozlowski, Gregor

In: Journal of Biogeography, 2020, vol. 47, no. 3, p. 643–657

Aim To establish a complete database of Juglandaceae at a spatiotemporal scale and develop a phylogeographic framework with which to elucidate the distributional patterns, diversity patterns, origins, evolution, and conservation priority regions of this family. Location Worldwide. Taxon Walnut family (Juglandaceae). Methods Data on the distribution of all the extant and fossil species of...

The last Palaeoproteus (Urodela: Batrachosauroididae) of Europe

Vasilyan, Davit ; Yanenko, Vadym

In: Scientific Reports, 2020, vol. 10, p. 2733

The Batrachosauroididae are an enigmatic group of salamanders known from the Cretaceous and Tertiary of North America and Europe. In Europe, the family is known only by two species of the genus Palaeoproteus. The genus has limited distribution in Western and Central Europe. In the present paper, we describe a new species, Palaeoproteus miocenicus, from the early late Miocene (11–9 Ma) of...

Sedimentary record of arc-continent collision along mesozoic SW north america (Siuna belt, Nicaragua)

Andjić, Goran ; Escuder‐Viruete, Javier ; Baumgartner‐Mora, Claudia ; Baumgartner, Peter O. ; Mitchell, Simon F. ; Caron, Michèle ; Caus, Esmeralda

In: Tectonics, 2019, vol. 38, no. 12, p. 4399–4425

The western margin of the Caribbean Plate is a typical example where oceanic and continental terranes have amalgamated by subduction, collision, and strike‐slip processes. The boundaries between these blocks, as well as their tectonostratigraphic records, are generally covered by younger deposits and dense tropical vegetation, which may hamper reconstructing the accretionary evolution of...
