In this study we present 19 new or re-analysed series of glacier-wide seasonal mass balance for the Swiss Alps based on direct measurements. The records partly start around 1920 and continue until today. Previously unpublished and unevaluated observations of point winter and annual balance are compiled from various sources and archives. These highly valuable datasets have not yet been...

Thèse de doctorat : Université de Neuchâtel, 2009 ; Th. 2089.

La famille des Sapindaceae est importante d’un point de vue économique et comprend plus de 1900 espèces (distribuées dans approximativement 140 genres; par exemple Litchi, Paullinia), majoritairement distribuées en zone tropicale. Cependant, certains genres peuvent coloniser les zones tempérées. Depuis plus d’un siècle, la définition de cette famille (plus particulièrement la...

In: Journal of Biogeography, 2009, vol. 36, p. 1-15

Aim The distribution range of Lactuca serriola, a species native to the summer-dry mediterranean climate, has expanded northwards during the last 250 years. This paper assesses the influence of climate on the range expansion of this species and highlights the importance of anthropogenic disturbance to its spread. Location Central and Northern Europe. ...
