Variation and control of growth-form in the moss Hylocomium splendens

Summary, in English

The moss Hylocomium splendens has both sympodial and monopodial forms of growth. One aim of this study was to document the growth-form of shoots from different populations. A further aim was to discover the extent to which genetic or environmental factors determine whether monopodial or sympodial growth-form is predominant in a population. Switching between growth-forms within shoots occurs in most populations. Populations in forest habitats in temperate to mid-Arctic environments have predominantly sympodial shoots whereas shoots of populations from tundra habitats, in high-Arctic environments or at high altitudes, are predominantly monopodial. Transplant experiments showed that sympodial and monopodial shoots can respond plastically, by changing growth-form to some extent in different environments, and that high nutrient availability is an important environmental factor in promoting sympodial growth-form. However, even after 14 years, transplants did not show the same variation in growth-form as shoots in natural populations at the transplant sites. This suggests that populations are also genetically differentiated with respect to growth-form.
