Exploring water governance arrangements in the swiss alps from the perspective of adaptive capacity

Schneider, Flurina ; Homewood, Christine

In: Mountain Research and Development, 2013, vol. 33, no. 3, p. 225–233

In times of increasing uncertainty because of climate and socioeconomic changes, the ability to deal with uncertainty and surprise is an essential requirement for the sustainability of alpine water governance. This article aims to contribute to the understanding of the adaptive capacity of water governance arrangements in the Swiss Alps and to propose options for reforms. To this purpose, we...

Clypeina helvetica Morellet and Morellet, 1918, revisited. A Priabonian (Late Eocene) dasycladalean alga from the Diablerets Nappe of the Helvetic Alps, southwestern Switzerland

Schlagintweit, Felix ; Bover-Arnal, Telm ; Menkveld-Gfeller, Ursula ; Strasser, André

In: Facies, 2013, vol. 58, no. 1, p. 287-297

The dasycladale Clypeina helvetica was described and illustrated with six drawings by Morellet and Morellet (Bull Soc Géol Fr 4o ser 18:102–105, 1918) from the “Bartonian” of the Helvetic Zone of southwestern Switzerland. Since then, C. helvetica has not been reported again neither from Switzerland nor from any other locality. Abundant material sampled from the Priabonian Diablerets Member...

Late Eocene transgressive sedimentation in the western Swiss Alps: Records of autochthonous and quasi-autochthonous biofacies on a karstic rocky shore

Bover-Arnal, Telm ; Jaramillo-Vogel, David ; Showani, Aso ; Strasser, André

In: Palaeogeography, Palaeoclimatology, Palaeoecology, 2011, vol. 312, no. 1-2, p. 24-39

Carbonate karst unconformities represent primary sequence-stratigraphic boundaries but, where sealed by marine sedimentary successions, also signify ancient rocky shores. During the Late Eocene (Priabonian), a shallow sea flooded the deeply karstified and brecciated Cretaceous carbonate bedrocks of the western Swiss Alps. Transgression resulted in the formation of a rocky archipelago of basement...

Assessing ‘Quality’: The unfolding of the ‘Good’—Collective decision making in juries of urban design competitions

Van Wezemael Joris Ernest ; Silberberger, Jan M. ; Paisiou, Sofia

In: Scandinavian Journal of Management, 2011, vol. 27, no. 1, p. 167-172

The radical orientation towards the future; the notion of novelty, experimentation and creativity makes an architectural competition a fascinating object – not least for management studies. In the paper at hand we discuss findings of an ethnographic study on the jury assessment sessions of four recent architectural competitions in Switzerland. We consider these meetings as a laboratory from...

A comparison of recent and fossil large, high-spired gastropods and their environments : the Nopparat Thara tidal flat in Krabi, South Thailand, versus the Swiss Kimmeridgian carbonate platform

Waite, Richard ; Strasser, André

In: Facies, 2011, vol. 57, no. 2, p. 223-248

High-spired nerineoid gastropods are abundant in the tropical Kimmeridgian carbonate deposits of the Swiss Jura Mountains. Understanding the mode of life of this extinct group of gastropods is crucial for palaeoenvironmental reconstructions. The knowledge on their ecology is, however, limited by the near absence of comparable large high-spired gastropods in Recent carbonate systems. Large...

What can sown wildflower strips contribute to butterfly conservation?: an example from a Swiss lowland agricultural landscape

Haaland, Christine ; Bersier, Louis-Félix

In: Journal of Insect Conservation, 2011, vol. 15, no. 1-2, p. 301-309

The objective of this study was to compare butterfly abundances and diversity between wildflower strips and extensively used meadows to identify which butterfly species can be supported by establishing wildflower strips. Butterflies were recorded along transects during one season in twenty-five sown wildflower strips and eleven extensively used meadows in a Swiss lowland agricultural landscape...

Evidence for oxic conditions during oceanic anoxic event 2 in the northern Tethyan pelagic realm

Westermann, S. ; Caron, Michèle ; Fiet, N. ; Fleitmann, D. ; Matera, V. ; Adatte, T. ; Föllmi, K. B.

In: Cretaceous Research, 2010, vol. 31, no. 5, p. 500-514

Upper Cenomanian pelagic sediments from the northern Alpine Helvetic fold-and-thrust belt (northern Tethyan margin) coeval with Oceanic Anoxic Event (OAE) 2 are characterized by the temporal persistence of micrite sedimentation and lack of organic carbon-rich layers. We studied an expanded section in the Chrummflueschlucht (east of Euthal, Switzerland), which encompasses the OAE 2 time interval....

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...

Controls on facies mosaics of carbonate platforms : a case study from the Oxfordian of the Swiss Jura

Strasser, André ; Védrine, Stéphanie

In: Perspectives in Carbonate Geology: A Tribute to the Career of Robert Nathan Ginsburg, 2009, p. 199–213

Modern shallow-water carbonate systems commonly display a complex pattern of juxtaposed depositional environments with a patchy facies distribution (facies mo saics). On ancient carbonate platforms, the reconstruction of lateral facies distribution is often hampered not only by discontinuous outcrop but also by lack of suffi ciently high time resolution. This case study from the Oxfordian...
