Morphological, hydrological, biogeochemical and ecological changes and challenges in river restoration : the Thur River case study

Schirmer, M ; Luster, J ; Linde, N ; Perona, P ; Mitchell, E.A.D ; Barry, D.A ; Hollender, J ; Cirpka, O.A ; Schneider, P ; Vogt, T ; Radny, D ; Durisch-Kaiser, E

In: Hydrology and Earth System Sciences, 2014, vol. 18, no. 6, p. 2449-2462

River restoration can enhance river dynamics, environmental heterogeneity and biodiversity, but the underlying processes governing the dynamic changes need to be understood to ensure that restoration projects meet their goals, and adverse effects are prevented. In particular, we need to comprehend how hydromorphological variability quantitatively relates to ecosystem functioning and services,...

Long time behavior of stochastic population models

Marmet, Bastien ; Benaïm, Michel (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2014.

The object of this thesis is the study of the asymptotic behavior of two classes of stochastic population models that both can be viewed as small random perturbations of a deterministic population dynamic. The first of these models is a discrete time Markov chain modeling the evolution of a population game with N players and d types. The second model is a constrained diffusion process modeling...

Stage 0 sporulation gene A as a molecular marker to study diversity of endospore-forming Firmicutes

Wunderlin, Tina ; Junier, Thomas ; Roussel-Delif, Ludovic ; Jeanneret, Nicole ; Junier, Pilar

In: Environmental Microbiology Reports, 2013, vol. 5, no. 6, p. 911-924

In this study, we developed and validated a cultureindependent method for diversity surveys to specifically detect endospore-forming Firmicutes. The global transcription regulator of sporulation (spo0A) was identified as a gene marker for endosporeforming Firmicutes. To enable phylogenetic classification, we designed a set of primers amplifying a 602 bp fragment of spo0A that we...

Candidatus Renichlamydia lutjani, a Gram-negative bacterium in internal organs of blue-striped snapper Lutjanus kasmira from Hawaii

Corsaro, Daniele ; Work, Thierry M

In: Diseases of Aquatic Organisms, 2014, vol. 98, no. 3, p. 249-254

The blue-striped snapper Lutjanus kasmira (Perciformes, Lutjanidae) are cosmopolitan in the Indo-Pacific but were introduced into Oahu, Hawaii, USA, in the 1950s and have since colonized most of the archipelago. Studies of microparasites in blue-striped snappers from Hawaii revealed chlamydia-like organisms (CLO) infecting the spleen and kidney, characterized by intracellular basophilic...

Formalized modeling of qualitative case studies

Han, Dong ; Stoffel, Kilian (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2013 ; 2399.

This thesis aims to solve the problems of data modelization and processing emerging in qualitative case studies. Established on grounded theory, a comprehensive method is proposed, initially elaborated in the form of a workflow solution. A suit of ontologies are proposed serving for knowledge representation, integration, and extraction. Based on this knowledge, topic analysis is conducted to...

Towards bridging the gap between reprensentation and formalism in the context of systems life cycle management processes

Simon, Eric ; Stoffel, Kilian (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2013 ; 2400.

In the context of systems development life cycles (SDLC), a gap exists between the representations of the involved methodologies as process on the one hand, for example using business process model and notation (BPMN), and the formalisms that would provide the level of analysability necessary to validate the corresponding processes on the other hand beyond mere execution, for instance Petri nets....

Transposable element and genome evolution following hybridization in wild wheats

Senerchia, Natacha ; Parisod, Christian (Dir.) ; Kessler, Félix (Codir.) ; Felber, François (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2014.

Genome dynamics is an essential process of eukaryote genome evolution. Hybridization and inter-species gene flow result in new interactions among divergent genomes and may reveal genetic incompatibilities having accumulated after the origin of species. Being highly mutagenic and repressed by various epigenetic mechanisms, transposable elements (TEs) are postulated to play a central role in...

Habitat partitioning of denitrifying bacterial communities carrying nirS or nirK genes in the stratified water column of Lake Kinneret, Israel

Junier, Pilar ; Kim, Ok-Sun ; Witzel, Karl-Paul ; Imhoff, Johannes F ; Hadas, Ora

In: Aquatic Microbial Ecology, 2008, vol. 51, p. 129-140

The community composition of denitrifying bacteria was studied in the stratified water column of Lake Kinneret. The nitrite reductase genes nirS and nirK were amplified by PCR from water samples taken at 1, 14, 19 and 22 m depth, which represent the epi-, meta- and hypolimnion of the lake. The PCR products were analyzed with terminal restriction fragment length polymorphism (T-RFLP)...
