Abstract
Insight from new technology in rangeland grazing systems Inger Hansen, Lise Grøva, Michael Angeloff and Oddbjørn Kaasa Although digital technologies and innovations are increasingly being adopted and accepted in intensive livestock systems, they are poorly developed and implemented in extensive livestock farming systems. On-animal sensors have potential to remotely monitor and identify changes in animal behaviour, such as illness, accidents or depredation. Real time monitoring of livestock may allow farmers and ranchers to respond more rapidly when animals become ill, and by this ensure both production and welfare With the rapid increase in new data from digital technologies from livestock rangeland grazing systems, there is a need to explore the potential for new knowledge and new tools that these data may provide. The potential lies in multisource data analysis to generate new insight on sheep behaviour, interactions and possible criteria for Early Warning Systems (EWS). EWS is in high demand by farmers, authorities and all stakeholders to ensure the sustainable management of our rangeland grazing resources. In Norway we have now started a pilot work to integrate data from GPS tracking collars on free ranging sheep with individual sheep health and production data sources, as well as vegetation maps, weather conditions, human activity and predator killings. Since 2015, Meråker grazing group, consisting of 25 sheep farmers, have used GPS tracking collars on about 2000 ewes from June to September. The data set consists of more than 9 million positions, allowing analysis of the sheep's movement related to numerous environmental and production factors. Integration of these position data with production-, health-, large carnivores- and other explanatory variables, and analysis of these multisource data, has potential to be a game changer for rangeland grazing systems. This presentation will highlight the the potiential for new insight in these farming systems.

Abstract
Reasonable chemical nitrogen (N) reduction and water-soluble amino acid fertilizers (WAAF) application can mitigate the negative effects of excessive N supply. Here, we reported that a 30% N reduction (T1) led to attenuated plant growth and decreased fruit quality of strawberries, which could be overwhelmingly restored by additional WAAF application (T2). To explore the underlying mechanism, comparative transcriptomic analysis was performed. Results revealed significant expression changes of genes involved in metabolisms of starch and sucrose, ascorbate and aldarate, carbon (C) and N, glyoxylate and dicarboxylate and so on. In consistence with the increased ascorbic acid (AsA) content and sugar/acid ratio, WAAF application upregulated GLDH, SPS and β-GE genes and downregulated APX, ICL and MS genes. Additionally, the differential expression of PK, IDH, GDH and SPX was consistent with the shift from C flux to N metabolism and the improved phosphorus (P) accumulation resulted from WAAF application. Our study will be helpful for understanding the effect of N reduction and WAAF application on strawberry fruit quality.
