American Journal of Botany, Volume 113, Issue 1, January 2026.Abstract Premise Evolutionary theory predicts polymorphism should be rare; however, intraspecific variation in floral color is common and can be attributed to genetic drift, plasticity, or variable selection. Examining floral color polymorphism both within contact zones and across a species' range can reveal the mechanisms maintaining this variation ...

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.

Ecology and Evolution, Volume 15, Issue 12, December 2025.The inducement, functions of flower color change (FCC) and its ecological effects have been studied by controlling pollination, accurate statistics of pollen transfer and visiting behavior in a typical distylous species. The results showed that limiting pollen input–output can delay fading time of spots, adding fake spots to old flowers can improve ...

Nordic Journal of Botany, Volume 2025, Issue 12, December 2025.Campanula teucrioides Boiss. is a critically endangered species found in a single locality in western Turkey. Determining the population size of C. teucrioides and conducting reproductive biology studies are of great importance in determining the necessary strategy for the conservation of the species. The area where the plant distributed was determined

Is there interspecific fruit set in distylous, synchronopatric species of Erythroxylum P. Browne (Erythroxylaceae)? [PDF]
Brazilian Journal of BiologySympatric congeneric species that overlap the flowering period and have morphologically similar flowers tend to be pollinated by the same groups of pollinators, facilitating interspecific pollination and hybridization.

Ecology and Evolution, 2019 The frequent transition from outcrossing to selfing in flowering plants is often accompanied by changes in multiple aspects of floral morphology, termed the “selfing syndrome.” While the repeated evolution of these changes suggests a role for natural ...

The island syndrome in plants on New Zealand's outlying islands: a review
New Zealand Journal of Botany, Volume 63, Issue 5, Page 2300-2324, December 2025.ABSTRACT The island syndrome is defined as a suite of predictable and consistent differences between island and mainland organisms. In seed plants, much of what we know about the island syndrome comes from work in the Southwest Pacific, which is comprised of the three main islands of New Zealand and ten surrounding archipelagos.
