dc.description.abstract | Introduction: The high frequency of polyploidy in the evolutionary history of many
plant groups occurring in the Mediterranean region is likely a consequence of its
dynamic paleogeographic and climatic history. Polyploids frequently have distinct
characteristics that allow them to overcome the minority cytotype exclusion. Such
traits may enable polyploid individuals to grow in habitats different from their
parentals and/or expand to new areas, leading to spatial segregation. Therefore,
the successful establishment of polyploid lineages has long been associated with
niche divergence or niche partitioning and the ability of polyploids to cope with
different, often more stressful, conditions. In this study, we aimed to explore the
role of environmental variables associated with the current distribution patterns of
cytotypes within the polyploid complex Linum suffruticosum s.l..
Methods: The distribution and environmental niches of the five main cytotypes
of Linum suffruticosum s.l. (diploids, tetraploids, hexaploids, octoploids and
decaploids) were studied across its distribution range. Realized environmental
niche of each cytotype was determined using niche modelling tools, such as
maximum entropy modelling and niche equivalency and similarity tests.
Results: Differences in the environmental conditions of L. suffruticosum s.l.
cytotypes were observed, with polyploids being associated with habitats of
increased drought and soil pH, narrower temperature ranges and decreased soil
water and cation exchange capacities. Diploids present the widest environmental
niche, and polyploids occupy part of the diploid niche. Although some polyploids
have equivalent potential ecological niches, cytotypes do not co-occur in nature.
Additionally, the ecological niche of this polyploid complex is different between
continents, with North African habitats being characterised by differences in soil
texture, higher pH, and low cation exchange capacity, precipitation and soil water
capacity and higher temperatures than habitats in southwest Europe.
Discussion: The different ecological conditions played a role in the distribution of
cytotypes, but the mosaic distribution could not be entirely explained by the
environmental variables included in this study. Other factors, such as reproductive
isolation and competitive interactions among cytotypes, could further explain the
current diversity and distribution patterns in white flax. This study provides relevant data
on the niche requirements of each cytotype for further competition and reciprocal
transplant experiments. further competition and reciprocal transplant experiments. | es |
