AbstractThis investigation was conducted to identify the content of metals in Calluna vulgaris (family Ericaceae), Empetrum nigrum (family Ericaceae), Festuca vivipara (family Poaceae) and Thymus praecox subsp. arcticus (family Lamiaceae), as well as in the soils where they were growing in eight geothermal heathlands in Iceland. Investigation into the vegetation of geothermal areas is crucial and may contribute to their proper protection in the future and bring more understanding under what conditions the plants respond to an ecologically more extreme situation. Plants from geothermally active sites were enriched with metals as compared to the same species from non-geothermal control sites (at an average from about 150 m from geothermal activity). The enriched metals consisted of Cd, Co, Cu, Fe and Ni in C. vulgaris; Cd, Mn and Ti in E. nigrum; Hg and Pb in F. vivipara; and Cd, Fe and Hg in T. praecox. Notably, C. vulgaris, E. nigrum, F. vivipara and T. praecox had remarkably high concentrations of Ti at levels typical of toxicity thresholds. Cd and Pb (except for C. vulgaris and F. vivipara) were not accumulated in the shoots of geothermal plants. C. vulgaris from geothermal and control sites was characterised by the highest bioaccumulation factor (BF) of Ti and Mn; E. nigrum and F. vivipara by the highest BF of Ti and Cr; and T. praecox by the highest BF of Ti and Zn compared to the other elements. In comparison with the other examined species, F. vivipara from geothermal sites had the highest concentration of Ti in above-ground parts at any concentration of plant-available Ti in soil.

XVI. On the leaf-arrangement of the crowberry ( empetrum nigrum )

Pursuing the study of leaf-arrangement, the author finds that the crowberry of our moors ( Empetrum nigrum ) habitually exhibits a peculiar mole of variation in the arrangement of the leaves on different parts of the same twig. Out of fifty crowberry-twigs taken at random, only four (and these fragments) preserved the same arrangement throughout. In the remaining forty-six the leaf-arrangement was found to undergo a progressive change in ascending from the base of the twig to the summit— a change from a simpler order to others more complex. In general the basal order was that denoted by the fraction ⅖; and this was found to pass most frequently into 2/7, which in turn was found to pass into 2/9, with or without an intermediate set of whorls of 4:2/9 generally passed into whorls of 5, sometimes into 2/11, which was the most complex arrangement that was met with in this plant. The following is a list of the transitions found in the fifty specimens:— In all these instances the striking peculiarity to be observed is that the arrangement passes from an order belonging to one phyllotactic series ( e. g. from the order ⅖ in the primary series ½, ⅓, ⅖, &c.) to an order belonging to another phyllotactic series ( e. g. to the order 2/7 in the secondary series ⅓, 1/4, 2/7, &c.), and that this is a phenomenon which could not result from uniform vertical condensation of the lower arrangement; whereas in other plants the ordinary transition is from one order to another of the same series ( e. g. from ⅖ to ⅜, 5/13, 8/21 &c.), and is such as would result from uniform vertical condensation of the lower arrangement (as the author has shown in a paper read before the Royal Society on the 30th April, 1874: see Proc. vol. xxii. p. 298).

Seed germinability of some common dwarf shrubs and seed-bank composition were studied in young pine forests along a pollution gradient from Severonickel smelter in Monchegorsk, northern Russia. Samples for seed germination and seed-bank trials were taken from sites representing different zones of pollution. Generally, germinability of dwarf shrub seeds was not affected by distance from pollution source, except for Empetrum nigrum ssp. hermaphroditium. The average density per site of seedlings that emerged from seed-bank samples varied between 278 and 416 seedlings/m2. Empetrum nigrum ssp. hermaphroditum and Betula sp. dominated in seed banks. Calluna vulgaris was also numerous at one site. As a whole, seed-bank taxa were well represented in the above ground vegetation. There were no significant differences in seedling density between sites for dominant taxa. Our results indicate that seeds can retain viability even under a heavy pollution load and thus form a potential for vegetation recovery in polluted sites. Key words: seed germination, seed bank, recovery, pollution, coniferous forest.
