“…Secondly, it has been demonstrated in the previous paper in this series (McNeilly and Antonovics, 1967) that other isolating mechanisms are also operative and therefore differences in self-fertility may not be very extreme.…”

“…Agrostis tenuis was collected from a copper mine at Drws-y-Coed, Caernarvonshire, and Anthoxanthum odoratum from a lead and zinc mine at Trelogan, Flintshire. These transects have been described by McNeilly (1967) and McNeilly and Antonovics (1967). Both cross a sharp boundary between mine and pasture and heavy metal tolerance changes abruptly at the boundary.…”

“…Flowering time differences between plants have been found in populations or many species (e.g., Ashton, 1975;Bawa, 1983;Cooper, 1959;Florence, 1964;Frankie et aL, 1974;McNeilly and Antonovics, 1968;Medway, 1972;Stern and Roche, 1974;Westerman, 1971). In such populations the potential exists for allele frequencies in the outcross pollen pooi to change during the flowering season as the flowers open at different times may show different genotype frequencies.…”

“…However, Aston and Bradshaw (1966) and McNeilly and Antonovics (1968) reported substantial gene flow between populations of grasses and yet genetic diversity being maintained over relatively short distances. As indicated by the genotypic differences between adult and seed populations, this must be due to rather strong contrasting selection pressures.…”
