The influence of ant-attendance on aphid behaviour investigated with the electrical penetration graph technique

Rauch, Gisep ; Simon, Jean-Christophe ; Chaubet, Bernard ; Haack, Lucie ; Flatt, Thomas ; Weisser, Wolfgang W.

In: Entomologia Experimentalis et Applicata, 2002, no. 102, p. 13-20

For themutualistic interaction between the aphidMetopeurum fuscoviride Stroyan (Homoptera:Aphididae) and the ant Lasius niger L. (Hymenoptera: Formicidae) it has been shown that ant-tended aphids develop faster, reproduce at a higher rate, and live longer than aphids not tended by ants. We used electrical penetration graphs (EPG) to investigate if behavioural patterns differ between ant-tended...

Gestion des risques : diversification, couverture et assurance

Schipperijn, Antonin ; Cho, Thomas (Dir.)

Mémoire de bachelor : Haute école de gestion de Genève, 2018 ; TDEE 363.

Depuis une décennie, les termes de risque et de gestion des risques occupent le devant de la scène du monde financier. Certes, ces termes ne sont pas nouveaux, mais c’est notamment à cause de (grâce à) la crise financière de 2008 que l’intérêt pour ces notions a été ravivé. La demande dans le monde financier en termes de gestion des risques ne cesse de croître bien évidemment....

Towards a Holarctic synthesis of peatland testate amoeba ecology : Development of a new continental-scale palaeohydrological transfer function for North America and comparison to European data

Amesbury, Matthew J ; Booth, Robert K ; Roland, Thomas P ; Bunbury, Joan ; Clifford, Michael J ; Charman, Dan J ; Elliot, Suzanne ; Finkelstein, Sarah ; Garneau, Michelle ; Hughes, Paul D.M ; Lamarre, Alexandre ; Loisel, Julie ; Mackay, Helen ; Magnan, Gabriel ; Markel, Erin R ; Mitchell, Edward A.D ; Payne, Richard J ; Pelletier, Nicolas ; Roe, Helen ; Sullivan, Maura E ; Swindles, Graeme T ; Talbot, Julie ; van Bellen, Simon ; Warner, Barry G

Fossil testate amoeba assemblages have been used to reconstruct peatland palaeohydrology for more than two decades. While transfer function training sets are typically of local-to regional-scale in extent, combining those data to cover broad ecohydrological gradients, from the regional-to continental- and hemispheric-scales, is useful to assess if ecological optima of species vary geographically...

SWISSCIT Index on Citizenship Law in Swiss Cantons: Conceptualisation, Measurement, Aggregation

Arrighi, Jean-Thomas ; Piccoli, Lorenzo

(nccr on the move ; 18)

In the Swiss federal context, the acquisition of citizenship through ordinary naturalization, the enjoyment of electoral rights as a foreign resident, and the retention of the franchise as a Swiss citizen abroad is not uniformly defined through a single federal law but co-determined by the cantons. In this explanatory note, we introduce SWISSCIT, a set of indicators measuring how inclusive...

Multimodal communication in aphasia: perception and production of co-speech gestures during face-to-face conversation

Preisig, Basil C. ; Eggenberger, Noëmi ; Cazzoli, Dario ; Nyffeler, Thomas ; Gutbrod, Klemens ; Annoni, Jean-Marie ; Meichtry, Jurka R. ; Nef, Tobias ; Müri, René M.

In: Frontiers in Human Neuroscience, 2018, vol. 12, p. -

The role of nonverbal communication in patients with post-stroke language impairment (aphasia) is not yet fully understood. This study investigated how aphasic patients perceive and produce co-speech gestures during face-to-face interaction, and whether distinct brain lesions would predict the frequency of spontaneous co-speech gesturing. For this purpose, we recorded samples of conversations...
