Progressively excluding mammals of different body size affects community and trait structure of ground beetles

Wang, Xiaowei ; Steiner, Magdalena ; Schütz, Martin ; Vandegehuchte, Martijn L. ; Risch, Anita C.

In: Oikos, 2018, vol. 127, no. 10, p. 1515–1525

Mammalian grazing induces changes in vegetation properties in grasslands, which can affect a wide variety of other animals including many arthropods. However, the impacts may depend on the type and body size of these mammals. Furthermore, how mammals influence functional trait syndromes of arthropod communities is not well known. We progressively excluded large (e.g. red deer, chamois),...

An emerging system to study photosymbiosis, brain regeneration, chronobiology, and behavior: the marine acoel symsagittifera roscoffensis

Arboleda, Enrique ; Hartenstein, Volker ; Martinez, Pedro ; Reichert, Heinrich ; Sen, Sonia ; Sprecher, Simon ; Bailly, Xavier

In: BioEssays, 2018, vol. 40, no. 10, p. 1800107

The acoel worm Symsagittifera roscoffensis, an early offshoot of the Bilateria and the only well-studied marine acoel that lives in a photosymbiotic relationship, exhibits a centralized nervous system, brain regeneration, and a wide repertoire of complex behaviors such as circatidal rhythmicity, photo/geotaxis, and social interactions. While this animal can be collected by the thousands and...

Mobilité étudiante internationale : raisons d’étudier en Suisse, stratégies, expériences et projets d’avenir

Renggli, Christina ; Riaño, Yvonne

In: Géo-Regards, revue neuchâteloise de géographie (Les étudiants internationaux), 2017, vol. 10, p. 71-91

Cet article analyse les raisons, stratégies, expériences et projets d’avenir des étudiantes et étudiants internationaux qui viennent en Suisse dans le cadre de leur formation tertiaire. L’Université de Berne sert d’étude de cas. Un sondage en ligne a été envoyé à toutes les personnes scolarisées à l’étranger et immatri-culées dans cette université durant l’année...

Does a good argument make a good answer? Argumentative reconstruction of children's justifications in a second order false belief task

Lombardi, Elisabetta ; Greco, Sara ; Massaro, Davide ; Schär, Rebecca ; Manzi, Federico ; Iannaccone, Antonio ; Perret-Clermont, Anne-Nelly ; Marchetti, Antonella

In: Learning, Culture and Social Interaction, 2018, vol. 18, p. 13-27

This paper proposes a novel approach to interpret the results of a classical second-order false belief task (the ice cream man task) administered to children in order to investigate their Theory of Mind. We adopted a dialogical perspective to study the adult-child discussion in this research setting. In particular, we see the adult-child conversation as an argumentative discussion in which...

Linear response approach to active Brownian particles in time-varying activity fields

Merlitz, Holger ; Vuijk, Hidde D. ; Brader, Joseph M. ; Sharma, Abhinav ; Sommer, Jens-Uwe

In: The Journal of Chemical Physics, 2018, vol. 148, no. 19, p. 194116

In a theoretical and simulation study, active Brownian particles (ABPs) in three- dimensional bulk systems are exposed to time-varying sinusoidal activity waves that are running through the system. A linear response (Green-Kubo) formalism is applied to derive fully analytical expressions for the torque-free polarization profiles of non- interacting particles. The activity waves induce fluxes...

Biochronological and palaeobiogeographical significance of the earliest Miocene mammal fauna from Northern Vietnam

Antoine, Pierre-Olivier ; Made, Jan van der ; Métais, Grégoire ; Phuc, Laq The ; Quan, Quý Tr??ng ; Schneider, Simon ; Tran, Dang Ngoc ; Vasilyan, Davit ; Viet, Luong The ; Böhme, Madelaine

In: Palaeobiodiversity and Palaeoenvironments, 2018, vol. 98, no. 2, p. 287–313

Current scientific knowledge of Tertiary fossils from south of the Ailao Shan-Red River shear zone is extremely poor, in sharp contrast with the situation nowadays, as the area of Laos and Vietnam is regarded as a global hotspot of biodiversity. In this context, the few localities that yielded fossil assemblages are of first importance for the understanding of Cenozoic palaeobiogeography and...

Making borders from below: the emergence of the Turkish–Iraqi Frontier, 1918–1925

Tejel Gorgas, Jordi

In: Middle Eastern Studies, 2018, vol. 54, no. 5, p. 811-826

This article proposes to re-examine the Turkish–Iraqi Frontier dispute by observing the strategies and attitudes of local populations, in particular in the border areas, between 1918 and 1925, a time when the region became a battleground of British and Turkish agents seeking to secure the loyalties of the local community leaders. The latter played a relevant role in two fundamental and...

Developing a framework of minimum standards for the risk assessment of alien species

Roy, Helen E. ; Rabitsch, Wolfgang ; Scalera, Riccardo ; Stewart, Alan ; Gallardo, Belinda ; Genovesi, Piero ; Essl, Franz ; Adriaens, Tim ; Bacher, Sven ; Booy, Olaf ; Branquart, Etienne ; Brunel, Sarah ; Copp, Gordon Howard ; Dean, Hannah ; D?hondt, Bram ; Josefsson, Melanie ; Kenis, Marc ; Kettunen, Marianne ; Linnamagi, Merike ; Lucy, Frances ; Martinou, Angeliki ; Moore, Niall ; Nentwig, Wolfgang ; Nieto, Ana ; Pergl, Jan ; Peyton, Jodey ; Roques, Alain ; Schindler, Stefan ; Schönrogge, Karsten ; Solarz, Wojciech ; Stebbing, Paul D. ; Trichkova, Teodora ; Vanderhoeven, Sonia ; Valkenburg, Johan van ; Zenetos, Argyro

In: Journal of Applied Ecology, 2018, vol. 55, no. 2, p. 526–538

Biological invasions are a threat to biodiversity, society and the economy. There is an urgent need to provide evidence-based assessments of the risks posed by invasive alien species (IAS) to prioritize action. Risk assessments underpin IAS policies in many ways: informing legislation; providing justification of restrictions in trade or consumer activities; prioritizing surveillance and rapid...

Application of carbon-chlorine isotopic analysis to determine the origin and fate of chlorinated ethenes in groundwater

Badin, Alice ; Hunkeler, Daniel (Dir.) ; Schirmer, Mario (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2015.

Chlorinated ethenes are ubiquitous groundwater contaminants posing a threat to one of our main drinking water sources. Despite their spill history dating back to more than 40 years ago, these contaminants are still found in groundwater in numerous industrially developed countries due to their persistence, difficult characterisation in the subsurface and resulting challenging remediation. When...
