The record of Deinotheriidae from the Miocene of the Swiss Jura Mountains (Jura Canton, Switzerland)

Gagliardi, Fanny ; Maridet, Olivier ; Becker, Damien

In: bioRxiv, 2021, p. 244061

The Miocene sands of the Swiss Jura Mountains, long exploited in quarries for the construction industry, have yielded abundant fossil remains of large mammals. Among Deinotheriidae (Proboscidea), two species, Prodeinotherium bavaricum and Deinotherium giganteum, had previously been identified in the Delémont valley, but never described. A third species, Deinotherium levius, from the locality of...

French-speaking Swiss coffee consumer habits and coffee farmers’ living conditions

Dupont-Wuillemin, Fanny ; Shepherd, Mark (Dir.)

Mémoire de bachelor : Haute école de gestion de Genève, 2020 ; TDIBM 75.

The coffee industry and particularly coffee producers are facing difficult and challenging times. For years coffee prices have been falling and therefore producers have seen their revenue shrinking. This situation can be somewhat counterintuitive for French-speaking Swiss coffee consumers who have seen the selling price of their caffeine intake increase over time. However, the drop in coffee...

New material of “Eurysternidae” (Thalassochelydia, Pan-Cryptodira) from the Kimmeridgian of the Swiss Jura Mountains

Püntener, Christian ; Anquetin, Jérémy ; Billon-Bruyat, Jean-Paul

In: Palaeovertebrata, 2020, vol. 43, no. 1, p. e2

The region of Porrentruy (Swiss Jura Mountains) is known for its rich and diverse assemblage of Late Jurassic coastal marine turtles (Thalassochelydia). Dominated by the “Plesiochelyidae”, this assemblage also includes representatives of the two other thalassochelydian groups, the “Thalassemydidae” and “Eurysternidae.” In this study, we present new shell-based material from Porrentruy...

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...

Tectonics of the Neuchâtel Jura Mountains: insights from mapping and forward modelling

Rime, Valentin ; Sommaruga, Anna ; Schori, Marc ; Mosar, Jon

In: Swiss Journal of Geosciences, 2019, vol. 112, no. 2, p. 563–578

This study focuses on a geological section in the Jura Mountains across the villages of Travers, La Brévine in Switzerland, and Morteau in France. Field mapping was conducted to complement and densify existing data. A kinematically and geometrically consistent forward model has been developed to understand and interpret the observed surface structures. The proposed solution features a...

Integrated bio- and cyclostratigraphy of Middle Triassic (Anisian) ramp deposits, NW Bulgaria

Ajdanlijsky, George ; Strasser, André ; Götz, Annette E.

In: Geologica Carpathica, 2019, vol. 70, no. 4, p. 325–354

A cyclostratigraphic interpretation of peritidal to shallow-marine ramp deposits of the early Middle Triassic (Anisian) Opletnya Member exposed in outcrops along the Iskar River gorge, NW Bulgaria, is presented. Based on facies trends and bounding surfaces, depositional sequences of several orders can be identified. New biostratigraphic data provide a time frame of the studied succession with...

Mountain permafrost degradation documented through a network of permanent electrical resistivity tomography sites

Mollaret, Coline ; Hilbich, Christin ; Pellet, Cécile ; Flores-Orozco, Adrian ; Delaloye, Reynald ; Hauck, Christian

In: The Cryosphere, 2019, vol. 13, no. 10, p. 2557–2578

Mountain permafrost is sensitive to climate change and is expected to gradually degrade in response to the ongoing atmospheric warming trend. Long-term monitoring of the permafrost thermal state is a key task, but problematic where temperatures are close to 0 ∘C because the energy exchange is then dominantly related to latent heat effects associated with phase change (ice–water), rather...
