Living (stained) foraminifera in the Lesser Syrtis (Tunisia): influence of pollution and substratum

El Kateb, Akram ; Beccari, Valentina ; Stainbank, Stephanie ; Spezzaferri, Silvia ; Coletti, Giovanni

In: PeerJ, 2020, p. e8839

Foraminifera are protozoans with biomineralized tests that can be successfully used as a low cost monitoring tool to assess the health status of marine environments. Living benthic foraminiferal assemblages can provide essential information on natural and/or anthropogenic stresses and provide baseline conditions for studies on fossil material. Several studies have highlighted the negative impact...

Monitoring rock glacier kinematics with satellite synthetic aperture radar

Strozzi, Tazio ; Caduff, Rafael ; Jones, Nina ; Barboux, Chloé ; Delaloye, Reynald ; Bodin, Xavier ; Kääb, Andreas ; Mätzler, Eva ; Schrott, Lothar

In: Remote Sensing, 2020, vol. 12, no. 3, p. 559

Active rock glaciers represent the best visual expression of mountain permafrost that can be mapped and monitored directly using remotely sensed data. Active rock glaciers are bodies that consist of a perennially frozen ice/rock mixture and express a distinct flow-like morphology indicating downslope permafrost creep movement. Annual rates of motion have ranged from a few millimeters to...

A substantial discount on ski passes : a synthetic control analysis

Wallimann, Hannes

(Working Papers SES ; 507)

The synthetic control method serves as an appropriate and promising approach to do quantitative comparison research. However, the method is rarely used in the context of tourism. We fill this research gap by applying the method to the case of a Swiss mountain destination. Alpine tourist destinations have suffered from a declining demand in the last decade. Fewer tourist visit ski resorts....

The Mre11-Nbs1 interface is essential for viability and tumor suppression

Kim, Jun Hyun ; Grosbart, Malgorzata ; Anand, Roopesh ; Wyman, Claire ; Cejka, Petr ; Petrini, John H.J.

In: Cell reports, 2017, vol. 18, no. 2, p. 496-507

The Mre11 complex (Mre11, Rad50, and Nbs1) is integral to both DNA repair and ataxia telangiectasia mutated (ATM)-dependent DNA damage signaling. All three Mre11 complex components are essential for viability at the cellular and organismal levels. To delineate essential and non-essential Mre11 complex functions that are mediated by Nbs1, we used TALEN-based genome editing to derive Nbs1...
