Variation in ploidy level and phenology can result in large and unexpected differences in demography and climatic sensitivity between closely related ferns

Abstract: Our results indicate that populations of closely related ferns can show large differences in population performance, mainly related to recruitment rates and frond phenology, and that these differences may depend greatly on climatic conditions. Our findings provide a first indication that (allo)polyploidization in ferns can have a significant effect on population dynamics.

“…At least in early recruitment, the C. tinaei species complex does not fit the speciation models that predict tetraploid superiority. This finding is relevant since variation in gametophyte‐related recruitment rates causes strong demographic differences between related cytotypes (De Groot et al., ). Future investigations should assess whether the coexistence of the study species is allowed by prezygotic isolation due to the niche differentiation and spatial segregation observed in the field.…”

“…Це одна з переваг, яка забезпечує їхню витривалість до затінення. Тому рослини P. aculeatum, що в основному зростають за таких умов [7,34], повинні мати специфічну структурно-функціональну організацію фотосинтетичного апарату.…”
