• Autopolyploid establishment under gametophytic self-incompatibility: the impact of self-fertilization and pollen limitation · 2026

  Résumé de la publication : Polyploidy is widespread in plants, yet the establishment of neo-polyploids is limited by minority cytotype exclusion (MCE). As polyploidy has been associated with higher selfing rates in empirical studies, a shift from self-incompatibility (SI) to self-compatibility (SC) may help overcome MCE, particularly…

• The contribution of non-additive genetic effects to the genetic variance of polyploid species · 2026

  Résumé de la publication : Whole genome duplication is a common mutation in eukaryotes with far-reaching phenotypic effects. The resulting morphological, physiological, and fitness consequences and how they affect the survival probability of newly polyploid lineages are intensively studied, but very little is known about the effect…

• How environment and genetic architecture of unreduced gametes shape the establishment of autopolyploids · 2026

  Résumé de la publication : Abstract It is broadly assumed that polyploidy success results from increased fitness associated with whole genome duplication due to higher tolerance to stressful conditions. In agreement, several theoretical models found that, among other factors, a better tolerance to new environmental conditions can…

• Resource partitioning and modernization of arthropod feeding strategies on Pennsylvanian medullosalean foliage from the Nord-Pas-de-Calais Coalfield, France · 2026

  Résumé de la publication : In recent years, there has been a dramatic increase in studies on plant-arthropod interactions in the fossil record. However, relatively few studies have targeted pre-Permian floras, which has hindered the reconstruction of trophic relationships in Carboniferous coal-forming ecosystems.Here, we document new evidence…

• Faunal distribution and palaeoenvironmental trends in the Lower Ordovician of the Montagne Noire, France: insights into the Cabrières Biota · 2026

  Résumé de la publication : In the southern Montagne Noire, France, the upper Floian Cabrières Lagerstätte yielded an atypical and diverse marine assemblage dominated by algae and sponges. It contrasts with the Fezouata Shale, Morocco, the only other known high-latitude Lower Ordovician Lagerstätte where non-trilobite arthropods and…
