“…However, in the case of species with spongy, brittle rhizomes, like in the studied C. rivulare, large patches disintegrate. This enables the ger- mination of seeds and the development of seedlings in the newly created gaps (Borkowska, 2004). Despite a high density of ramets and their close proximity in a patch, we found that they had a high level of genetic differentiation, which resulted in high values of heterozygosity and the polymorphism information content (PIC) index.…”

“…At present, C. rivulare is most abundantly represented in macroforbs in the initial stage of succession. The population is characterised by a repeated seedling recruitment pattern (Eriksson, 1989;Borkowska, 2004).…”

“…Accumulating necromass (produced by mortifying ramets) might also have limited seed germination on tussock cores. It has been repeatedly found that disruption of the vegetation cover and changes in microhabitat conditions relocate seeds to the soil surface and allow their germination (Thompson and Grime 1979;Thompson 1992;Łaska 2001;Borkowska 2004). Field observations (unpublished data) and the results of this study show that tussocks rarely contain other (growing) species.…”

This study examined a non-soil seed bank deposited inside the tussock cores of Carex cespitosa, a perennial plant with a tussock growth form. Based on the vertical structure of the seed bank in 20 tussock cores, the history of changes in plant species composition during succession in an unmowed grassland in the Białowie_ za National Park was reconstructed. Three horizontal layers were distinguished in each tussock core: upper (corresponding to the initial forest stage), middle (transitory stage-forb and swamp communities) and bottom (early successional stagegrassland). The results showed that seeds of both the parental species and other species were stored inside the C. cespitosa tussock cores. More than 50,000 seedlings were found, representing 42 vascular plant species. The highest number of seedlings was recorded in the middle layer. Seedlings of swamp species were dominant in the upper layer, whereas seedlings of grassland species were dominant in the other layers. The highest number of C. cespitosa seedlings was observed in the upper layer. The most common seedlings in the middle layer belonged to the species Epilobium palustre, Lythrum salicaria and Cirsium palustre. In the bottom layer, the most common species of seedlings were grassland species, e.g. Lychnis flos-cuculi and Ranunculus repens. The protected seed bank inside this tussock species reflected recorded changes in species composition of these grasslands through time. Seed banks in this and other tussock-forming species represent a potentially useful tool for reconstructing recent developmental history of plant communities.

“…The abundant colonisation of openings in swards by seedlings of T. europaeus was observed previously by several authors (Hitchmough 2003;Vandvik 2004;Kochanowska & Gamrat 2007;KostrakiewiczGierałt 2012). At the same time, it should be pointed out that the role of disturbances as safe sites for the recruitment of clonal plant seedlings in meadows was demonstrated repeatedly (Eriksson 1997;Borkowska 2004;Kostrakiewicz-Gierałt 2014a). On the other hand, animal activities such as wallowing, trampling and browsing may lead to uprooting genets of T. europaeus or damage to their above-ground parts.…”

Abstract:The investigations presented here were carried out in years 2013-14, in a Molinietum caeruleae meadow with interrupted plant cover caused by animal activity (patch I); abandoned Molinietum caeruleae meadows with untouched plant canopy, dominated by species with considerable height of the above-ground parts (patches II-VI); as well as the edge (patch VII) and the interior (patch VIII) of a birch woodlot. The height of standing vegetation and soil moisture increased in subsequent patches, whereas the light availability at ground level showed inverse tendency. The abundance of Trollius europaeus subpopulations in all studied patches was rather low. In patch I, juvenile individuals dominated, while in other stands -flowering adults prevailed. The lack of temporal variability in the number of basal leaves observed in patches III, IV, V, VI and VII might be due to lack of available area necessary for clonal proliferation of ramets, while the increase of basal leaves number in other sites might suggest unlimited iterative growth. The dimensions of basal leaves in consecutive years were constant in majority of subpopulations, while they showed strong spatial variability increasing gradually from patch I to patch VII and, subsequently, decreasing in patch VIII. The substantial dimensions of basal leaves may enable better light capture in sites with great level of lateral shade, while smaller dimensions in patches located within a woodlot may be due to shade from above created by trees. Lack of temporal variability and presence of substantial spatial variability in the number and height of generative stems, as well as flower production might enhance chances for successful pollination in a competitive environment. Significant changes of follicle number in time and space suggest successful process of pollination in all patches excluding patch VIII. The weak condition of the ramet clusters in patch I is not compensated by considerable seedling recruitment, whereas the satisfactory state of the ramet clusters in patches II-VIII may not suffice for the long-term maintenance of populations in colonized areas.
