Metropolises out-of Platanthera chlorantha (PS1 and you can PS2, PB1–PB4, circles) and Cephalanthera rubra (CK1 and CK2, CB1–CB7, triangles) communities during the north-east Poland.

Studies town and you will sampling

I examined six P. chlorantha and you will nine C. rubra populations within the northern-east Poland (Bialowieza and Knyszynska Primeval Forest, Szeszupa lake valley) when you look at the absolute, semi-natural and you may anthropogenic organizations away from national and you will land areas, reserves and safe areas, particularly Natura 2000 sites ( Fig. 1). While they are based in protected portion, of numerous exist towards the train embankments, together ways and you can paths from inside the forests or perhaps in clearings.

The new sampling processes relied into the people dimensions. Leaf samples regarding the majority of ramets within this communities each and every types were taken (but population PS2; Desk step 1); no samples were extracted from busted or most younger individuals. 100 and ninety-eight trials regarding P. chlorantha and you will 95 trials regarding C. rubra was basically obtained. Leaf muscle is maintained freeze until it can be kept during the ?80 °C, pending allozyme data. All collected products were used for allozyme studies.

N, population size; N_S, number of samples analysed; N_G/N_W, number of generative ramets/number of vegetative ramets; P_POL, percentage of polymorphic loci; A, mean number of alleles per locus; H_O, observed heterozygosity; H_E, expected heterozygosity; F_Was, inbreeding coefficient; G, number of genotypes, G/N_S, clonal diversity; G_U, number of unique genotypes; G_U %, percentage of unique genotypes (Fischer’s exact test: P < 0.05, **P < 0.01, ***P < 0.001); #, sum of parameters.

Allozyme polymorphism

Homogenates were made by milling this new will leave inside a barrier having 2-mercaptoethanol (1%, v/v). Electrophoresis is actually accomplished towards the 10% starch gels and you will Titan III cellulose acetate dishes (Helena Labs, Beaumont, Texas, USA) pursuing the simple electrophoretic procedures. Fifteen loci (Adh, Gdh, Got-1, Got-dos, Idh-step one, Idh-dos, Mdh-step 1, Mdh-dos, Me, Pgi, Pgm, 6Pgd, Skd, Sod, Tpi) from inside the P. chlorantha and you may 16 loci into the C. rubra (Adh, Got-1, Got-dos, Gdh, Idh-1, Idh-dos, Mdh-1, Mdh-2, Me, 6Pgd, Pgi, Pgm, Skd, Sod, Tpi-1, Tpi-2) was basically investigated. A couple of electrode/gel barrier expertise were used to respond to chemical expertise: GDH and you can Had (10% lithium-borate horizontal starch serum during the pH 8.2/8.3) and you will MDH, SKD and you can TPI (10% histidine-citrate boundary from the pH seven.0/eight.0). Enzyme hobby staining observed Soltis Soltis ( 1989). Others enzyme expertise (ADH, IDH, Myself, 6PGD, PGI, PGM, SOD) was basically screened using Titan III cellulose acetate plates want Spiritual Sites dating, which were fixed using Tris-glycine buffer in the pH 8.6 and you will Tris-citrate boundary in the pH 7.6 (Richardson, Adams Baverstock, 1986). The brand new enzyme staining formulas had been considering Soltis Soltis ( 1989) and you may Richardson mais aussi al. ( 1986), that have changes.

Mathematical research

The data matrix of individuals was analysed using the TFPGA package (Miller, 1997), FSTAT 2.9.3 (Goudet, 2001) and GENEPOP 3.2 (Raymond Rousset, 1995) for calculation of standard measures of allozyme diversity: allelic frequencies, percentage of polymorphic loci (P_POL), number of alleles per locus (A), genetic diversity (i.e. observed H_O and expected heterozygosity H_E) and inbreeding coefficient (F_Are). The occurrence of unique alleles was used to describe population distinctiveness (Slatkin, 1985). Deviations from Hardy–Weinberg expectations were tested for the population by the Markov chain method (GENEPOP).

Parameters of within-population genotypic diversity were also estimated. Three different measures of clonal diversity were used: number of observed genotypes (G), number of genotypes unique to a single population (G_U) and the probability that the next ramet sampled would be a different genotype (G/N_S; where N_S is the number of ramets sampled). _POL, A, H_O and F_{Is actually}) and population size were tested with Spearman’s pairwise rank correlations (StatSoft, 1995).
