Vascular plant diversity in Swedish road verges of high conservation value is threatened by the invasive alien herb Lupinus polyphyllus Lindley

Nordic Journal of Botany, Volume 2026, Issue 4, April 2026.
Road verges can be important habitats for vascular plant communities and the organisms that, in turn, depend on them. However, the plant diversity in Swedish road verges is threatened by the invasive perennial plant Lupinus polyphyllus Lindl. Therefore, this study aimed to investigate the effects of L.

Genome‐Wide SNP Data and Species Distribution Modeling Reveal Population Structure and Conservation Implications of Primula wilsonii (Primulaceae)

Ecology and Evolution, Volume 16, Issue 1, January 2026.
This study investigates the genetic erosion and conservation of Primula wilsonii, a plant species with extremely small populations in Southwest China. Using genomic sequencing and species distribution models, the research identifies distinct genetic clusters, low genetic diversity, and significant genetic differentiation among populations, in the text ...

A pan‐European citizen science study shows population size, climate and land use are related to biased morph ratios in the heterostylous plant Primula veris

Journal of Ecology, Volume 114, Issue 1, January 2026.
A large‐scale citizen science study involving thousands of cowslip (Primula veris) observations from all over Europe revealed an unexpected prevalence of S‐morphs over L‐morphs, which was influenced by climatic as well as land use factors. Furthermore, general morph ratios were often unbalanced with the strongest shifts occurring in smaller populations.

Positive indirect effects outweigh negative direct effects of ungulate grazers on population growth of a grassland herb

Oikos, Volume 2025, Issue 10, October 2025.
Herbivores can affect plant population growth both directly through the damage they inflict to a focal species, and indirectly by moderating conditions for plant recruitment, nutrient cycling, competition and other biotic interactions, for example, through trampling, defecation, and grazing on surrounding vegetation.
