Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Throughout the Northern Hemisphere, changes in local and regional climate conditions are coupled to the recurring and persistent large-scale patterns of pressure and circulation anomalies spanning vast geographical areas, the so-called teleconnection patterns. Indeed, the atmospheric fluctuations described by the North Atlantic Oscillation (NAO) are closely associated with the last four decades of inter-annual variability in local snow and ice conditions observed in the Arctic. Since the NAO has also been connected with changes in the global climate, the behaviour of species, communities and other ecosystem elements at Zackenberg in relation to the NAO enables us to view these in circumpolar and global contexts. Large-scale systems like the NAO constitute the link between the global change and local climate variability to which ecosystem components respond. Here, we place selected ecosystem elements from the monitoring programme Zackenberg Basic presented in previous chapters in a circumpolar context related to NAO-mediated climatic changes. We begin by linking the local variability in winter weather conditions at Zackenberg to fluctuations in the NAO. We then proceed by linking the observed intra- and inter-annual behaviour of selected ecosystem elements to changes in the NAO. The functional ecosystem characteristics in focus are landscape gas exchange dynamics phenological patterns at different trophic levels, consumer-resource dynamics and community stability. The influence of the NAO is presented and discussed in a broader perspective based on information obtained from other arctic localities. The relation between the NAO and the Zackenberg winter weather, is nonlinear, reflecting differential effects of the NAO as the index moves between high and low phases. The inverse hyperbolic relationship found between the NAO and the amount of winter snow was also evident as non-linear response in organisms and systems to inter-annual changes in the NAO. Responses investigated included growth and reproduction in plants and animals, population dynamics and synchrony, inter-trophic interactions and community stability together with system feedback dynamics.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Real-time quantitative polymerase chain reaction (qPCR) technology is being widely used for high throughput diagnostics of pathogens in the food production chain as an alternative to the more time-consuming and laborious culture-based standard methods. This chapter discusses the basics of qPCR, including data analysis, PCR instruments, and detection chemistries. The importance of choosing appropriate pre-PCR processing strategies - i.e., sampling, sample preparation, and PCR chemistry - to avoid PCR inhibition and achieve correct quantification is furthermore included. Major novel trends such as portable PCR instruments for in-field diagnostics, high-resolution melting curve analysis, and digital PCR are addressed. Finally, some perspectives on future trends are given. © 2015 Elsevier Ltd. All rights reserved.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Salmonella remains one of the most important zoonotic pathogenic bacteria and is the causative agents of salmonellosis. The aim of this article is to give an overview of Salmonella and salmonellosis, starting by describing the characteristics of the microorganism Salmonella, including biochemical properties, physiology, classification, and nomenclature. Thereafter, the epidemiology of the organism is introduced, including the routes of transmission. Finally, the disease salmonellosis, the virulence mechanisms, and the occurrence in different types of food are described. © 2016 Elsevier Ltd. All rights reserved.
