Parasite‐driven replacement of a sexual by a closely related asexual taxon in nature

Lohr, Jennifer N. ; Haag, Christoph R.

In: Ecology, 2020, vol. 101, no. 10, p. -

Asexual species are thought to suffer more from coevolving parasites than related sexuals. Yet a variety of studies do not find the patterns predicted by theory. Here, to shine light on this conundrum, we investigate one such case of an asexual advantage in the presence of parasites. We follow the frequency dynamics of sexual and asexual Daphnia pulex in a natural pond that was initially...

Geodynamics, seismicity, and seismic hazards of the Caucasus

Ismail-Zadeh, Alik ; Adamia, Shota ; Chabukiani, Aleksandre ; Chelidze, Tamaz ; Cloetingh, Sierd ; Floyd, Michael ; Gorshkov, Alexander ; Gvishiani, Alexei ; Ismail-Zadeh, Tahir ; Kabanh, Mikhail K. ; Kadirov, Fakhraddin ; Karapetyan, Jon ; Kangarli, Talat ; Kiria, Jemal ; Koulakov, Ivan ; Mosar, Jon ; Mumladze, Tea ; Müller, Birgit ; Sadradze, Nino ; Safarov, Rafig ; Schilling, Frank ; Soloviev, Alexander

Being a part of ongoing continental collision between the Arabian and Eurasian plates, the Caucasus region is a remarkable site of moderate to strong seismicity, where devastating earthquakes caused significant losses of lives and livelihood. In this article, we survey geology and geodynamics of the Caucasus and its surroundings; magmatism and heat flow; active tectonics and tectonic stresses...

Genome insights of the plant-growth promoting bacterium Cronobacter muytjensii JZ38 with volatile-mediated antagonistic activity against Phytophthora infestans

Eida, Abdul Aziz ; Bougouffa, Salim ; L’Haridon, Floriane ; Alam, Intikhab ; Weisskopf, Laure ; Bajic, Vladimir B. ; Saad, Maged M. ; Hirt, Heribert

In: Frontiers in Microbiology, 2020, vol. 11, p. 369

Salinity stress is a major challenge to agricultural productivity and global food security in light of a dramatic increase of human population and climate change. Plant growth promoting bacteria can be used as an additional solution to traditional crop breeding and genetic engineering. In the present work, the induction of plant salt tolerance by the desert plant endophyte Cronobacter sp. ...

Tectonics of the Neuchâtel Jura Mountains: insights from mapping and forward modelling

Rime, Valentin ; Sommaruga, Anna ; Schori, Marc ; Mosar, Jon

In: Swiss Journal of Geosciences, 2019, vol. 112, no. 2, p. 563–578

This study focuses on a geological section in the Jura Mountains across the villages of Travers, La Brévine in Switzerland, and Morteau in France. Field mapping was conducted to complement and densify existing data. A kinematically and geometrically consistent forward model has been developed to understand and interpret the observed surface structures. The proposed solution features a...

Tectonics controls on fluvial landscapes and drainage development in the westernmost part of Switzerland: Insights from DEM-derived geomorphic indices

Radaideh, Omar M. A. ; Mosar, Jon

In: Tectonophysics, 2019, vol. 768, p. 228179

This work focuses particularly on the geomorphological evidence for the tectonic controls on the development of the present-day fluvial landscapes in the westernmost part of Switzerland. The tectonic deformation was evaluated on the basis of a combined analysis of several classical geomorphic indices (hypsometric curves and integrals, transverse topographic symmetry index, and channel's...
