Background and Aims Habitat degradation and landscape fragmentation dramatically lower population sizes of rare plant species. Decreasing population sizes may, in turn, negatively affect genetic diversity and reproductive fitness which can ultimately lead to local extinction of populations. Although such extinction vortex dynamics have been postulated in theory and modelling for decades, empirical evidence from local extinctions of plant populations is scarce. In particular, comparisons between current vs. historical genetic diversity and differentiation are lacking...
Effects of cold or warm ischemia and ex-vivo lung perfusion on the release of damage associated molecular patterns and inflammatory cytokines in experimental lung transplantationRoumen Parapanov, Arpad Hasenauer, Benoit Bedat, Jérôme Lugrin, Anne Debonneville, Etienne Abdelnour, Michel Gonzalez, Jean Perentes, Lise Piquilloud, Csaba Szabo, Thorsten Krueger & Lucas Liaudet
Lung transplantation (LTx) is associated with sterile inflammation, possibly related to the release of damage associated molecular patterns (DAMPs) by injured allograft cells. We have measured cellular damage and the release of DAMPs and cytokines in an experimental model of LTx after cold or warm ischemia and examined the effect of pretreatment with ex-vivo lung perfusion (EVLP).
Data from: Feeding habits of the Middle Triassic pseudosuchian Batrachotomus kupferzellensis from Germany and palaeoecological implications for archosaursEudald Mujal, Eudald Mujal, Christian Foth, Erin Maxwell, Dieter Seegis & Rainer Schoch
Bite traces on fossil bones are key to deciphering feeding ecology and trophic interactions of vertebrate past ecosystems. However, similarities between traces produced by different carnivorous taxa with similar dentitions and misidentifications due to equifinality hinder confident identifications of the bite makers. Here, we correlate bite traces with macroscopic wear and microanatomy of the teeth of the pseudosuchian archosaur Batrachotomus kupferzellensis from the Triassic Lower Keuper fossil lagerstätten (southern Germany), untangling its feeding habits and...
The Swiss Permafrost Bulletin is published annually and describes the key results of the permafrost monitoring in the Swiss Alps based on the field-data obtained in the framework of the Swiss Permafrost Monitoring Network PERMOS. This report covers the hydrological year 2021 (1 October 2020 to 30 September 2030).
