DNA metabarcoding reveals changes in the contents of carnivorous plants along an elevation gradient

Littlefair, Joanne E. ; Zander, Axel ; Sena Costa, Clara de ; Clare, Elizabeth L.

In: Molecular Ecology, 2019, vol. 28, no. 2, p. 281–292

Resource variation along abiotic gradients influences subsequent trophic interactions and these effects can be transmitted through entire food webs. Interactions along abiotic gradients can provide clues as to how organisms will face changing environmental conditions, such as future range shifts. However, it is challenging to find replicated systems to study these effects. Phytotelmata, such...

Al confine di Chiasso : regards sur l'évolution du travail du Corps des gardes-frontière tessinois et son impact sur le contrôle migratoire

Lacarbonara, Nicole ; Piguet, Etienne (Dir.)

Mémoire de master : Université de Neuchâtel, 2019.

Ce mémoire de master analyse l’évolution du travail des gardes-frontière à la frontière de la zone de Mendrisio (Tessin) des années 1990 à ce jour. Plus particulièrement, il s’agit d’étudier l’évolution des tâches et leurs applications par l’examen du discours et des souvenirs des gardes-frontière qui ont partagé avec moi leur expérience de terrain. Après avoir...

Essays on the globalization of firm ownership

Zhang, Xiqian ; Salva, Carolina (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2017 ; 2671.

This dissertation is constituted of three distinct chapters. The first chapter seeks to resolve a recent debate on whether sovereign wealth funds(SWFs) have non-financial objectives and politically distort firm performance. I find that, once stake size is considered, previous belief that SWFs would affect firm performance should be reformulated. SWFs rarely seek an influential stake in listed...

Des abeilles, des ruches et des humains : les Centres apicoles : des acteurs de la réalisation de la filière apicole au Burkina Faso

Boila, Zeno ; Fresia, Marion (Dir.) ; Aebi, Alexandre (Codir.)

Mémoire de master : Université de Neuchâtel, 2018 ; NET 900/431.

La présente étude se focalise sur les processus de structuration de la filière apicole au Burkina Faso et sur le rôle joué par les Centres apicoles ; des structures nées en tant qu’unités de transformation des premiers projets de développement en apiculture élaborés par certaines ONG étrangères durant la fin des années 1990 et le début des années 2000. En partant du constat...

We are ready for faunistic surveys of bdelloid rotifers through DNA barcoding : the example of Sphagnum bogs of the Swiss Jura Mountains = Listos para revisiones faunísticas de rotíferos bdelloideos por DNA barcoding: el caso de las turberas de Sphagnum de las montañas del Jura suizo

Fontaneto, Diego ; Eckert, Ester M ; Anicic, Nikoleta ; Lara, Enrique ; Mitchell, Edward A. D

In: Limnetica, 2019, vol. 38, no. 1, p. 213-225

The identification of biological diversity through DNA barcoding and metabarcoding of the organisms living in the field has the potential to revolutionise the way biological surveys and monitoring are performed. Yet, we still do not know if the current representativeness of the reference database of DNA sequence data is sufficient to allow such approaches. Here, we show that, at least for...

19. Multilingualism in Switzerland

Grünert, Matthias

In: Manual of Romance Sociolinguistics, 2018, p. 526-548

This chapter deals with the two Romance languages which are officially recognized as minority languages of Switzerland, Romansh and Italian, and with Francoprovençal and French dialects spoken marginally in the francophone area of Switzerland. Romansh, the language that has gained new recognition in the process leading to the quadrilingual Swiss Confederation, is considered in most detail. The...

Isotope fractionation due to diffusion and sorption of chlorinated hydrocarbons and its implications for identifying reactive processes in aquifer - aquitard systems

Wanner, Philipp ; Hunkeler, Daniel (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2016.

Chlorinated hydrocarbons are anthropogenic contaminants, which are known to be possibly carcinogenic to humans. Although the peak production of chlorinated hydrocarbons in the 1970ties was followed by a dramatic decrease in the subsequent decades, chlorinated hydrocarbons are still frequently detected in aquifer systems demonstrating their long-term persistence. When chlorinated hydrocarbons are...

Cyclostratigraphy of shallow-marine carbonates – limitations and opportunities

Strasser, André

In: Stratigraphy & Timescales, 2018, vol. 3, p. 151–187

The sedimentary record of ancient shallow-marine carbonate platforms commonly displays a stacking of different facies, which reflects repetitive changes of depositional environments through time. These changes can be induced by external factors such as cyclical changes in climate and/or sea level, but also by internal factors such as lateral migration of sediment bodies and/or changes in the...

La Formation du Grand Essert (Jura franco-suisse; Valanginien supérieur p.p. à Hauterivien supérieur basal) = The Grand Essert Formation (French-Swiss Jura Mountains; late Valanginian p.p. to earliest late Hauterivian)

Strasser, André ; Clavel, Bernard ; Monteil, Eric ; Charollais, Jean ; Piuz, André ; Mastransgelo, Bruno

In: Archives des Sciences, 2018, vol. 70, p. 205-282

Le terme de Formation du Grand Essert a été proposé en 2016 pour remplacer ceux de « Marnes d’Hauterive » auct. et « Pierre jaune de Neuchâtel » auct. attribués à l’« Hauterivien » auct. dans le Jura franco-suisse. L’objet de cette note est, dans un premier temps, de décrire et d’interpréter la lithologie de la coupe-type représentative de cette nouvelle formation,...
