Pollen Interference Between Rare and Common Species. [PDF]
Ecol EvolIn a multispecies greenhouse experiment, we performed hand pollination treatments between eight co‐occurring and co‐flowering plant species with varying rarity levels in Switzerland. We found that overall heterospecific pollen interference did not affect seed set nor seed number, used as proxies of recruitment, for neither common nor rare species.

American Journal of Botany, Volume 110, Issue 9, September 2023., 2023 Over 250 non‐native plants arrived on the Atlantic Coast of the United States with pre‐1900s ship ballast, and the authors show which of these species died out (as waifs or short‐lived rarities) and which still persist as local or widespread plants. Abstract Premise Understanding establishment and spread of non‐native plants is important in the face of

Telomerase RNA gene paralogs in plants – the usual pathway to unusual telomeres
New Phytologist, Volume 239, Issue 6, Page 2353-2366, September 2023., 2023 Summary Telomerase, telomeric DNA and associated proteins together represent a complex, finely tuned and functionally conserved mechanism that ensures genome integrity by protecting and maintaining chromosome ends. Changes in its components can threaten an organism's viability.
