“…The decrease of offspring emergence in GR and SA patches could be the consequence of light harvesting by tall grasses or willows with wide and spreading leaves. A similar effect of plant growing in the vicinity on recruitment of Iris sibirica and Trollius europaeus seedlings was observed previously by Kostrakiewicz (2007Kostrakiewicz ( , 2010 and Muncaciu et al (2010). Also, Hitchmough (2003) noted greater emergence of Trollius europaeus seedlings in mown, than in unmanaged wet grasslands.…”

Abstract:The observations were carried out in the years [2007][2008][2009][2010], in the Molinietum caeruleae meadows with different habitat conditions located in Kraków-Kostrze (southern Poland). The greatest number of seedlings of Trollius europaeus and Iris sibirica was recorded in patches dominated by low-statured species with delicate, procumbent stems or small-tussocks. The diminishing of offspring emergence in places prevailed by large-tussocks grasses, as well as in sites overgrown by willows could be a consequence of poor harvesting practices, as well as the stagnation of water in local depressions. Irrespective of patch charracter, the seedling recruitment did not occur in a fully compact plant canopy, the highest number of offspring was observed in gaps without moss and necromass layers, while the greatest abundance of genets was found in openings left after the removal of bryophytes, litter and above ground parts of plants. The decrease in offspring number noted in gaps resulted from the removal of living and died plants combined with top soil raking, which might caused the partial depletion of soil seed bank reserves. Regardless of the patch type, a significantly higher appearance of seedlings of Trollius europaeus and Iris sibirica was found in the largest gaps than in the smallest ones. In light of the performed studies, it might be concluded that gap creating seems to be a very effective way of active protection of Iris sibirica and Trollius europaeus populations.

“…Practical measurements to mitigate climate change effects in bogs and fens may include restoration of the water regime and reduction of fertiliser input. Mitigation of climate change effects on wet meadows may include restoration or maintenance of the water regime and of traditional hay making practices (Muncaciu, Gafta, Cristea, Rosca-Casian, & Goia, 2010).…”

“…While still common in many European alpine regions, the species is becoming increasingly threatened in lowland regions due to its requirement for moist meadows (Muncaciu et al 2010;Lemke 2011). In Switzerland moist habitats have undergone drastic changes during the last century, with up to 90 % of the former areas being lost due to drainage, deterioration and fertilization (Broggi and Schlegel 1989;Bowman et al 2008).…”

Genetic variation and plant performance in fragmented populations of globeflowers (Trollius europaeus) within agricultural landscapes

The management of remnant populations in highly fragmented landscapes requires a thorough understanding of the processes shaping population persistence. We investigated relationships between population characteristics (i.e. size, density and pollinator abundance), offspring performance, genetic diversity and differentiation in Trollius europaeus, a plant with a nursery pollination system. In 19 populations of different sizes and located in north-east Switzerland, an area which has undergone widespread land use changes over the last decades, we assessed neutral genetic diversity (N total = 383) using AFLPs and plant performance in a greenhouse experiment (N total = 584) using competition and control treatments. Overall genetic differentiation was low (F ST = 0.033) with a marginal significant isolation by distance effect (P = 0.06) indicating (historical) genetic connectivity among the populations. Mean expected heterozygosity was H E of 0.309 (0.0257-0.393) while inbreeding coefficients (F IS ) were significant in only three populations. Genetic diversity was not related to population size, plant density or pollinator abundance. Plant performance was reduced under competition (P \ 0.001) but the severity of competition was independent of genetic diversity and population size. In summary, remnant populations of T. europaeus retain genetic diversity and seem capable of persisting under the present conditions within an agricultural matrix. T. europaeus is a perennial herb, thus it may require several generations for the negative effects of fragmentation and isolation to manifest. Our findings indicate that small populations are as important as large populations for the conservation and management of genetic resources.
