Data from: An experimental test of local adaptation among cytotypes within a polyploid complex
The geographic distributions of polyploids suggest they can have distinct and sometimes broader niches compared to diploids. However, relatively few field experiments have investigated whether range differences are associated with local adaptation or reflect other processes, such as dispersal limitation. In three years of transplants across the elevational ranges of five cytotypes in the Claytonia perfoliata complex, we found evidence for local adaptation. In at least one study year germination was higher within the natural range for each cytotype, and four of the five cytotypes attained larger biomass within their natural range. Fitness within and beyond range varied across years, with two instances of cytotypes showing higher fitness beyond the range, highlighting a potential role of temporal variability in cytotype differentiation. Polyploids as a group did not outperform diploids, but the cytotype with highest fitness across environments was a hexaploid reported to be invasive. Our results suggest that differences in geographic ranges within the C. perfoliata complex reflect local adaptation of cytotypes. Although we did not find a general polyploid advantage, our findings support the idea that occasional polyploid cytotypes exhibit high fitness relative to other cytotypes, and contribute to growing evidence supporting ecological differentiation of cytotypes within polyploid complexes.

FIGURE 1. Map of sample sites of Pannonian populations of Odontarrhena tortuosa under study. Population codes follow Table 1. Taxa (O. tortuosa subsp. heterophylla and O. tortuosa subsp. tortuosa), ploidy levels and the type of substrate are indicated by symbol colours and shapes.

FIGURE 4. Canonical discriminant analysis (CDA 1) of 329 individuals of Odontarrhena tortuosa based on 27 morphological characters and three predefined groups corresponding to populations from three geographic regions differing in the type of substrate: (1) sand dunes in southwestern Slovakia, central Hungary and northern Serbia (tetraploid populations 24GRE, 244ORK, 471MCL, 473UZO, 539KIS, 540KSH), (2) sandy and rocky screes in central Hungary (diploid populations 13PIL, 447TOK, 537DOR, 538CSI), (3) calcareous rocks in eastern Slovakia (diploid populations 201JBV, 552KRV, 553HRH). 95 % isodensity circles are depicted. Population codes follow Table 1. For total canonical structure, see Table 5.

CDA 2 with diploids (black) and tetraploids (white) as two predefined groups, B. CDA 3 with O. tortuosa subsp. tortuosa (white) and O. tortuosa subsp. heterophylla (black) as two predefined groups.

FIGURE 3 in Diploid and tetraploid cytotypes and subspecies of Odontarrhena tortuosa (Brassicaceae) in Pannonia: differences in morphology, ecology and genome size
FIGURE 3. Principal coordinate analysis (PCoA) of 13 populations of Odontarrhena tortuosa based on 27 morphological characters and population means. The first three components explain 46.3%, 18.5% and 10.1% of the variation, respectively. Different colours and symbols are used to mark the two ploidy levels, two subspecies and populations from three regions differing in the type of substrate: diploids of O. tortuosa subsp. heterophylla from rocks of the Slovak Karst and Vihorlat Mts in eastern Slovakia (black squares), diploids of O. tortuosa subsp. tortuosa from habitats with sandy and rocky screes in the Gerecse, Pilis and Buda Mts in the northern part of central Hungary (black circles), and tetraploids of O. tortuosa subsp. tortuosa from sand dunes in southwestern Slovakia, central Hungary and northern Serbia (white circles).
FIGURE 2 in Diploid and tetraploid cytotypes and subspecies of Odontarrhena tortuosa (Brassicaceae) in Pannonia: differences in morphology, ecology and genome size
FIGURE 2. Monoploid relative genome size variation of Pannonian populations of Odontarrhena tortuosa sorted into groups based on three criteria: ploidy level (A), assignment to a subspecies (B) and the type of substrate (C). Boxes define the 25th and 75th percentiles, vertical lines within boxes indicate medians, and whiskers extend from minimum to maximum values.
