High-frequency palaeoenvironmental changes on a shallow carbonate platform during a marine transgression (Late Oxfordian, Swiss Jura Mountains)

Védrine, Stéphanie ; Strasser, André

In: Swiss Journal of Geosciences, 2009, vol. 102, no. 2, p. 247–270

Based on a well-established bio- and sequence-stratigraphic framework, a narrow time window in the Bimammatum ammonite zone (Late Oxfordian) is investigated in six Swiss Jura sections representing a shallow-water carbonate platform. From the detailed facies and microfacies analysis of oncoid-rich (Hauptmumienbank Member) and ooid-rich (Steinebach Member) limestones, a microfacies...

Target neuron prespecification in the olfactory map of Drosophila

Jefferis, Gregory S. X. E. ; Marin, Elizabeth C. ; Stocker, Reinhard F. ; Luo, Liqun

In: Nature, 2001, vol. 414, p. 204-208

In Drosophila and mice, olfactory receptor neurons (ORNs) expressing the same receptors have convergent axonal projections to specific glomerular targets in the antennal lobe/olfactory bulb, creating an odour map in this first olfactory structure of the central nervous system1, 2, ³. Projection neurons of the Drosophila antennal lobe send dendrites into...

Winter weather affects asp viper Vipera aspis population dynamics through susceptible juveniles

Altwegg, Res ; Dummermuth, Stefan ; Anholt, Bradley R. ; Flatt, Thomas

In: Oikos, 2005, vol. 110, no. 1, p. 55-66

Detailed studies on mammals and birds have shown that the effects of climate variation on population dynamics often depend on population composition, because weather affects different subsets of a population differently. It is presently unknown whether this is also true for ectothermic animals such as reptiles. Here we show such an interaction between weather and demography for an ectothermic...

Subduction and obduction processes in the Swiss Alps

Stampfli, G. M. ; Mosar, Jon ; Marquer, D. ; Marchant, R. ; Baudin, T. ; Borel, G.

In: Tectonophysics, 1998, vol. 296, p. 159

The significance of the Briançonnais domain in the Alpine orogen is reviewed in the light of data concerning its collision with the active Adriatic margin and the passive Helvetic margin. The Briançonnais which formerly belonged to the Iberian plate, was located on the northern margin of the Alpine Tethys (Liguro-Piémont ocean) since its opening in the early-Middle Jurassic. Together with the...
