How much can bulk stores help reduce carbon footprint by limiting plastic food packaging ?

Jarel Rodriguez, Anaïs ; Milet, Emmanuel (Dir.)

Mémoire de bachelor : Haute école de gestion de Genève, 2020 ; TDIBM 67.

This report focuses on the quantity of food packaging waste consumed by an average single individual, residing in Switzerland. It is based on the household budget survey published by the Federal Statistical Office (FSO). This budget survey mentions the food quantities monthly consumed by a single individual and thus, the packaging waste could be computed accordingly. The objective is to compare...

Tissue-specific transcription footprinting using RNA PoI DamID (RAPID) in Caenorhabditis elegans

Gómez-Saldivar, Georgina ; Osuna-Luque, Jaime ; Semple, Jennifer I. ; Glauser, Dominique A. ; Jarriault, Sophie ; Meister, Peter

In: Genetics, 2020, vol. 216, no. 4, p. 931–945

Differential gene expression across cell types underlies development and cell physiology in multicellular organisms. Caenorhabditis elegans is a powerful, extensively used model to address these biological questions. A remaining bottleneck relates to the difficulty to obtain comprehensive tissue-specific gene transcription data, since available methods are still challenging to execute and/or...

First fossil frog from Antarctica: implications for Eocene high latitude climate conditions and Gondwanan cosmopolitanism of Australobatrachia

Mörs, Thomas ; Reguero, Marcelo ; Vasilyan, Davit

In: Scientific Reports, 2020, vol. 10, p. 5051

Cenozoic ectothermic continental tetrapods (amphibians and reptiles) have not been documented previously from Antarctica, in contrast to all other continents. Here we report a fossil ilium and an ornamented skull bone that can be attributed to the Recent, South American, anuran family Calyptocephalellidae or helmeted frogs, representing the first modern amphibian found in Antarctica. The two bone...

The north-subducting Rheic Ocean during the Devonian: consequences for the Rhenohercynian ore sites

Raumer, Jürgen F. von ; Nesbor, Heinz-Dieter ; Stampfli, Gérard M.

In: International Journal of Earth Sciences, 2017, vol. 106, no. 7, p. 2279–2296

Base metal mining in the Rhenohercynian Zone has a long history. Middle-Upper Devonian to Lower Carboniferous sediment-hosted massive sulfide deposits (SHMS), volcanic-hosted massive sulfide deposits (VHMS) and Lahn-Dill-type iron, and base metal ores occur at several sites in the Rhenohercynian Zone that stretches from the South Portuguese Zone, through the Lizard area, the Rhenish Massif...

A review of the fossil record of turtles of the clade Thalassochelydia

Anquetin, Jérémy ; Püntener, Christian ; Joyce, Walter G.

In: Bulletin of the Peabody Museum of Natural History, 2017, vol. 58, no. 2, p. 317–369

The Late Jurassic (Oxfordian to Tithonian) fossil record of Europe and South America has yielded a particularly rich assemblage of aquatic pan-cryptodiran turtles that are herein tentatively hypothesized to form a monophyletic group named Thalassochelydia. Thalassochelydians were traditionally referred to three families, Eurysternidae, Plesiochelyidae, and Thalassemydidae, but the current...

A review of the fossil record of old world turtles of the clade pan-trionychidae

Georgalis, Georgios L. ; Joyce, Walter G.

In: Bulletin of the Peabody Museum of Natural History, 2017, vol. 58, no. 1, p. 115–208

Turtles of the clade Pan-Trionychidae have a rich fossil record in the Old World, ranging from the Early Cretaceous (Hauterivian) to the Holocene. The clade most probably originated in Asia during the Early Cretaceous but spread from there to the Americas and Europe by the Late Cretaceous, to India and Australia by the Eocene, and to Afro-Arabia by the Neogene. The presence of a single...

A review of the fossil record of basal mesozoic turtles

Joyce, Walter G.

In: Bulletin of the Peabody Museum of Natural History, 2017, vol. 58, no. 1, p. 65–113

Turtles (Testudinata) are the clade of amniotes characterized by a complete turtle shell. New insights into the phylogeny of the group have revealed that a diverse assemblage of fossil turtles populate the stem lineage that lead to the turtle crown (Testudines). To aid communication, the terms Mesochelydia and Perichelydia are herein defined for two internested clades more inclusive than...
