“…The greatest growth increments over the 8 wk period were attained by the hydric species D. uncinatus and B. austro-salebrosum and the hydric/ mesic B. pseudotriquetrum, the responses of the latter two being virtually identical (Figs 2, 3), A. depressinervis (xeric) grew the least, the mesic/xeric R. austro-georgicitm and the mesic P. alpestre having similar intermediate responses. Xerophytes, such as Andreaea, are noted for having inherently low growth rates (Smith, 1981;Furness & Grime, 19826;Longton, 1988) which might be related to their ability to exploit stressful habitats (Proctor, 1984).…”

“…This growth, as shoot extension or dry matter production, is broadly related to hahitat type and its associated moisture regime, the hydric D. uncinatus, with its wide ecological amplitude, having the highest rates, and the xerophyte A. depressinervis the lowest. However, as Furness & Grime (19826) emphasized, shoot extension as a measure of performance, might be invalid. Noakes (1991) observed that gro-wth on the water gradients could be nutrient-limited, a major problem when the water supply has a zero nutrient status.…”

SUMMARYThe dependence of shoot growth and growth form on water availability was studied experimentally in six species of maritime Antarctic moss. Under all conditions the largest growth increments were observed in the hydric .species Brachythecmm austro-salebrosum and Drepanocladus uncinatus. The xeric Andreaea depressinervis grew the least. Lateral shoot production varied within and between species. Over 50 % of the biomass produced in D. uncinatus was derived from lateral shoot production, vi^hereas Polytrichum atpestre produced very few lateral shoots and A, depressinervis produced none. Leaf density and leaf size also varied with total water content.In all species growth ceased at total water contents of 10O"o d. wt or less. However, the total water content at which maximum growth was observed differed between species. Racomitrium austro-georgicum (mesic/xeric) had tbe lowest optimum for growth at 370 "• of d. wt and D. uncinatus (hydnc) exhibited maximum growth between 890 and 2300 °o d. wt. Optimum total water contents for growth were greater than those at full turgor and published optima for net assimilation.Growth and total water content of these Antarctic mosses were similar to those reported for temperate species.

Question Global change is likely to strongly affect alpine and sub‐alpine regions, in which bryophytes are important components. Global change effects on sub‐alpine vegetation, bryophytes in particular, however, have been addressed in few studies. We ask if global warming and increased nitrogen (N) deposition, two of the most important components of global change, will have different effects on bryophyte communities and species in sub‐alpine coniferous and shrubland ecosystems. Location Eastern slope of the Tibetan Plateau. Methods We established a warming by N deposition experiment, using a 2 × 2 factorial design, replicated three times, in each of two sub‐alpine ecosystems. Effects on bryophytes at the community and species levels were evaluated after 4 (shrubland) and 5 (coniferous forest) years of warming and N deposition treatments. Results Bryophyte cover increased in the first two growing seasons and thereafter decreased until the end of the experiment in all treatments, most strongly in warming plots in both ecosystems and in N deposition plots in the coniferous forest. At the species level, the pleurocarpous bryophyte Pleurozium schreberi was resilient to warming but sensitive to N deposition, while the acrocarpous bryophytes Rhizomnium tuomikoskii and Racomitrium japonicum were resilient to N addition but sensitive to warming. Conclusions Effects of warming and increased N deposition on bryophytes were species‐ and to some extent also ecosystem‐specific in the experiment in the sub‐alpine region, indicating that bryophytes do not respond to global change as one single functional group. The observed species replacements in response to warming and N deposition may affect ecosystem processes.

“…This all might have contributed to the absence of significant results in this study. It is difficult to compare the seasonal bryophyte growth with results of other studies (Furness & Grime, 1982a;Jonsson & Sö derströ m, 1988;Bates, 1989;Wiklund & Rydin, 2004), because the authors only reported annual percentage growth and not seasonal rates. The most relevant published result to this study is the 32% of annual relative growth observed in the epixylic liverwort Ptilidium pulcherrimum (Jonsson & Söderströ m, 1988), which fits into the range observed here.…”

Seasonal patterns in growth and dynamics of 13 epixylic bryophyte species (six liverworts and seven mosses) were studied within permanent plots in the Ž ofínský prales old-growth forest in south-eastern Bohemia, Czech Republic. Transparencies were used to record positions and cover of bryophyte colonies within each plot twice a year (in spring and autumn) for periods of 1-4 years. Percentage growth of species populations and growth dynamics of their colonies were analysed in order to identify seasonality in their growth. Establishment of bryophyte colonies and their expansion, as well as pair-wise overgrowth of adjacent colonies of different species were compared in order to identify competitive interactions between bryophyte species. Bryophytes grew faster during the winter season (October-April) than during summer, and the various species did not differ in their percentage growth. The growth dynamics of bryophyte colonies was highly seasonal and the species differed in their dynamics pattern. The expansion and retreat (local extinction) of bryophyte species were greatest in winter, and the stability of colonies was, therefore, higher in summer. Interspecific competition among the species studied appears to be low.
