Eduquer à la condition terrestre

Pellaud, Francine ; Eastes, Richard-Emmanuel

In: Education relative à l'environnement, 2020, p. 1-19

Although sustainable development has succeeded in penetrating the economy, and most school curricula incorporate education on the subject, almost 30 years later, it is clear that mass extinction, pollution, social disparities, ecological disasters and overexploitation are our daily fare. Can this counterproductive and alarming result possibly be attributed to a concept that has appeased our...

Genetic structure of the endemic Papaver occidentale indicates survival and immigration in the Western Prealps

Pittet, Loïc ; Fragnière, Yann ; Grünig, Sandra ; Bétrisey, Sébastien ; Clément, Benoît ; Gerber, Emanuel ; Ronikier, Michał ; Kozlowski, Gregor ; Parisod, Christian

In: Alpine Botany, 2020, p. -

Climatic oscillations of the Quaternary rapidly compelled plant species to shift their geographical range. How alpine plant species responded to climate change, however, remains elusive and remnants of the cold-adapted flora that currently strive in restricted ranges as small, isolated populations have been particularly overlooked. To address the evolutionary history of such a ‘glacial...

Ecological immunity of "Anopheles gambiae" mosquitoes

Barreaux, Antoine ; Koella, Jacob (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2016.

Malaria is a vector borne disease caused by protozoan parasites and transmitted to humans by mosquitoes. It is one of the most deadly infectious diseases in the world, with more than one million deaths each year. Malaria is even more worrying in the context of climate change, as global warming is predicted to increase the transmission to humans and to influence vector-parasite interactions. To...

Disentangling the effects of external perturbations on coexistence and priority effects

Song, Chuliang ; Rohr, Rudolf P. ; Vasseur, David ; Saavedra, Serguei

In: Journal of Ecology, 2020, p. 1365-2745.13349

A major challenge in ecological research is to identify the tolerance of ecological communities to external perturbations. Modern coexistence theory (MCT) has been widely adopted as a framework to investigate the tolerance to perturbations in relative reductions of per capita growth rates, often using metrics that explicitly eliminate the independent role of intrinsic growth rates. More...

The foraging ecology of two neighbouring chimpanzee communities from Budongo Forest

Villioth, Jakob ; Newton-Fisher, Nicholas E. (Dir.) ; Zuberbühler, Klaus (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2019.

Chimpanzees (Pan troglodytes) often serve as a model species to test socio-ecological theories of foraging behaviour. Due to a high degree of fission-fusion dynamics, essential foraging variables, such as group size, patch size and travel distance, are expected to be more closely linked in chimpanzees than in animals that forage in cohesive groups. While it has been clearly established...

Impacts of urban gardening on soil quality, soil fauna and soil multifunctionality

Tresch, Simon ; Le Bayon, Claire (Dir.) ; Fliessbach, Andreas (Codir.) ; Moretti, Marco (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2019.

Urban gardens are important and at the same time popular greenspaces. As urban areas are expanding globally, urban gardens play an increasingly important role in contributing to essential ecosystem services, well-being of citizens, and biodiversity in a city. Gardening activities determine above- and belowground diversity of plants and insects. However, the effect of gardening activities on soil...

Reconquérir la ville après un épisode psychotique : pratiques, espaces et temporalités

Codeluppi, Zoé ; Söderström, Ola (Dir.) ; Conus, Philippe (Codir.) ; Matthey, Laurent (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2019.

The aim of this research is to investigate the role of the urban environment in the recovery process of psychosis. I look at the practices, spaces and temporalities of reconquering the city. I focus particularly on young people having recently experienced a first psychotic episode in the city of Lausanne, Switzerland. This analysis examines recovery from an ecological perspective that considers...

Evolution of the "Castanea sativa" - "Dryocosmus kuriphilus" - "Torymus sinensis" - system in southern Switzerland

Gehring, Eric ; Aebi, Alexandre (Dir.) ; Conedera, Marco (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2019.

The arrival of new organisms that may potentially become harmful for people and ecosystems has become a world-wide daily concern to the point that in Switzerland about 800 established alien species exist, of which at least 107 are considered invasive. A possible way to control such pests is by importing and releasing natural enemies from their countries of origin, letting them to act as so-called...

VAPYRIN Marks an endosomal trafficking compartment involved in arbuscular mycorrhizal symbiosis

Bapaume, Laure ; Laukamm, Sabine ; Darbon, Geoffrey ; Monney, Corinne ; Meyenhofer, Felix ; Feddermann, Nadja ; Chen, Min ; Reinhardt, Didier

In: Frontiers in Plant Science, 2019, vol. 10, p. -

Arbuscular mycorrhiza (AM) is a symbiosis between plants and AM fungi that requires the intracellular accommodation of the fungal partner in the host. For reciprocal nutrient exchange, AM fungi form intracellular arbuscules that are surrounded by the peri-arbuscular membrane. This membrane, together with the fungal plasma membrane, and the space in between, constitute the symbiotic interface,...
