Abstract
In boreal and subarctic regions, dwarf shrubs may dominate the ground cover in forests as well as open habitats. Therefore, their contribution to the carbon capture in these areas is important to quantify. The length of the growing season impacts greatly on the carbon capture and is also very variable depending on duration of the snow cover as well as daylenghts and temperatures. In a project studying many ecological aspects of dwarf shrubs in four sites in Norway, we compare a coastal and an inland site in the south and the north of the country. The coastal sites typically have less snow than the inland sites, whereas the southern sites have higher mean air temperatures than the northern sites. The extremes of these four sites are then the southern coastal site where the snowless season with favourable temperatures can come in April, versus the northern continental site where snowmelt and favourable temperatures may come in June when there is midnight sun. If the plants from varying locations are differently adapted to start photosynthesising and producing new leaves, it will impact on the seasonal carbon capture. To compare these abilities between sites, we collected plants from each site and grew them in controlled conditions giving them the same winter and spring startup conditions. The dwarf shrubs Calluna vulgaris and Empetrum nigrum are among the species we studied. Repeated measurements of photosynthesis rate, respiration rate and branch lengths were done to investigate the phenology. This presentation will show how the species differed between sites of origin and the results will be discussed with respect to the normal climate at each site.

Landrace cereals have become more popular among organic farmers in Europe. However, little is known about the response of landraces to environmental conditions and farmers’ management compared to modern cultivars. A co-designed field experiment, informed by Swedish farmers’ experiences of landrace cereals, was used to investigate how traits valued by organic farmers differ between four landrace and three modern varieties of spring wheat (Triticum aestivum L.) under different environmental conditions and depending on nutrient applications. The experiment was organically managed and consisted of four randomized complete blocks in four environments, comprising two sites during two consecutive years. The varieties responded similarly to fertilization. The most recent modern variety had the highest grain yield of all varieties but the lowest protein content. At low or medium initial availability of nitrogen, landraces were shown to yield similarly to modern organic varieties, give high and stable protein content, and in addition suppress weeds better and produce higher straw yields. In one experimental environment, the initial amount of soil mineral nitrogen was high, and all four landraces yielded considerably less than all modern varieties. These results show the potential for landraces to provide both food and ecosystem services under low-input organic conditions.

Maintaining forest resilience under climate change depends on understanding genetic adaptation and preserving diversity. Long-term common garden networks are essential for revealing how species and populations perform across life stages and environments. When strategically designed and deployed across diverse sites, including suboptimal ones, these networks provide critical empirical insights into adaptive capacity of forest tree species under future climate conditions.
