Abstract Key message 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.

The codling moth (Tortricidae: Cydia pomonella) is a common pest in fruit orchards all over the world that is known to have developed resistance against a variety of pesticides. With a rising concern over the negative effects from pesticides, nations like Norway have implemented integrated pest management (IPM) in their national strategy to lower pesticide use. IPM highlights semi-natural habitats (SNH) as key elements in conservation biological control, as they provide essential resources for natural enemies. The codling moth has life stages on the orchard floor where it may be exposed to ground dwelling predators such as carabid beetles (Coleoptera: Carabidae). While the role of carabids as predators in cereal field is well known, their contributions to biocontrol in fruit orchards remain understudied. The aim of this study was to explore how SNH influence ground dwelling predator communities in apple orchards and its possible impacts for biocontrol of the codling moth. By using pitfall traps, this study explored how carabid communities varied across a distance gradient from SNH to within orchards in three apple orchards in Eastern Norway, throughout one growth season. The study yielded 55 carabid species (n=949), of which three species made up around 59% of all specimens. Preliminary results suggest that communities further from the SNH are more abundant but less functional diverse. Fully detailed results will be presented during the conference.

Slugs represent one of the main pests for vegetable farmers. In Norway, the invasive Spanish slug, Arion vulgaris, is especially damaging and is listed as a severe threat on the Norwegian list of alien species. In small-scale, diversified horticultural systems, like market gardens and allotment gardens, pest problems may be exacerbated because of organic cultivation methods with limited use of conventional pest management. On the other hand, small-scale horticultural systems may foster greater local biodiversity through their diversified growing practices and limited pest management, and are often situated in areas more favourable to biodiversity compared to intensive, monocultural farmlands. Greater local biodiversity, in turn, might provide improved pest control by natural enemies. Carabid beetles are natural enemies of slugs, and earlier studies have shown that some species feed on eggs and juveniles of the Spanish slug. However, for many carabid beetles, it is unclear if, and to what extent, the Spanish slug, and other common slug pests, are preyed upon. In this project, we aim to: 1) quantify the abundance and species richness of carabid beetles in Norwegian market gardens and allotment gardens, 2) correlate carabid abundance and richness with slug abundance in market gardens, and 3) use molecular methods to establish whether common carabid species found in Norwegian smallscale horticultural systems contain slug DNA in their gut.

With an approximate production of 1.5 million tons annually, Norway remains as the world’s biggest producer of Atlantic salmon. Marine aquaculture sludge constitutes a major side stream from the aquaculture sector, which represents nutrients loss as well as a contributing factor to eutrophication of the ocean. Despite its elevated salt and sulphur concentrations, the high energy density of marine aquaculture sludge indicates its suitability as a substrate for biogas production. The microbial community driving anaerobic digestion represents a complex mixture of symbiotic relationships between bacteria and methanogenic archaea. Here, we investigate the microbial dynamics as well as reactor performance of two lab-scale reactors running solely on marine aquaculture sludge, from which we achieved continuous biogas production from reactors running on 100% marine aquaculture sludge. Hydraulic retention time was decreased from 20 to 4 days to determine the reactor’s maximum tolerable organic loading rate. Performance measurements, such as gas production and acid composition, pH and buffer capacity was observed. Initial microbial community analysis through 16S rRNA gene amplicon sequencing revealed a low diversity, yet specialized halotolerant microbial community during anaerobic digestion of marine aquaculture sludge. To broaden this knowledge, we employed a metagenome-centric metaproteomic approach, aiming to further elucidate the relationship between reactor performance measurements and changes in microbial community structure and activity in biogas reactors running on marine aquaculture sludge when subjected to reduced hydraulic retention time. Overall, our study aims to assess both the opportunities and limitations of using marine aquaculture sludge as a substrate for biogas production.
