AbstractWinter temperatures are projected to increase in Central Europe. Subsequently, snow cover will decrease, leading to increased soil temperature variability, with potentially different consequences for soil frost depending on e.g. altitude. Here, we experimentally evaluated the effects of increased winter soil temperature variability on the root associated mycobiome of two plant species (Calluna vulgaris and Holcus lanatus) at two sites in Germany; a colder and wetter upland site with high snow accumulation and a warmer and drier lowland site, with low snow accumulation. Mesocosm monocultures were set-up in spring 2010 at both sites (with soil and plants originating from the lowland site). In the following winter, an experimental warming pulse treatment was initiated by overhead infrared heaters and warming wires at the soil surface for half of the mesocosms at both sites. At the lowland site, the warming treatment resulted in a reduced number of days with soil frost as well as increased the average daily temperature amplitude. Contrary, the treatment caused no changes in these parameters at the upland site, which was in general a much more frost affected site. Soil and plant roots were sampled before and after the following growing season (spring and autumn 2011). High-throughput sequencing was used for profiling of the root-associated fungal (ITS marker) community (mycobiome). Site was found to have a profound effect on the composition of the mycobiome, which at the upland site was dominated by fast growing saprotrophs (Mortierellomycota), and at the lowland site by plant species-specific symbionts (e.g. Rhizoscyphus ericae and Microdochium bolleyi for C. vulgaris and H. lanatus respectively). The transplantation to the colder upland site and the temperature treatment at the warmer lowland site had comparable consequences for the mycobiome, implying that winter climate change resulting in higher temperature variability has large consequences for mycobiome structures regardless of absolute temperature of a given site.

Trifolium Repens L

Ten individual plants of Trifolium repens L. were transplanted into a 49-year-old cattle pasture in British Columbia. They were protected from grazing and their subsequent growth was monitored at 2- to 3-week intervals throughout the summer from May to October. The rate of stolon elongation was greatest (2.01 cm ∙ week−1) in late July and a maximum rate of node production (1.48 new nodes per stolon ∙ week−1) occurred in early August. As stolons extended through the pasture they encountered a number of different grass species: Dactylis glomerata, Holcus lanatus, Lolium perenne, Phleum pratense, and Poa spp. The stolons grew through a total of 2 m of H. lanatus neighborhood and produced only 3 branches, whereas they produced 11 branches in only 57.2 cm of P. pratense neighborhood. Neighboring grasses impose different local environments on the nodes and stolons of T. repens and consequently influence the dynamics of node production, the rate of stolon elongation, and the amount of stolon branching. Key words: stolon branching, neighbors, light quality, Trifolium repens.
