Abstract

1. Our understanding of how migratory wildlife populations affect incidence of in-fectious diseases spilling over into humans is limited. Ticks are expanding theirdistribution towards northern latitudes, causing emergence of tick- borne dis-eases. Deer serve as reproduction hosts for adult ticks, supporting the tick pop -ulations. However, in northern areas, deer populations are partially migratory,and migrants occupy high elevation summer ranges that are unsuitable for ticks.Migration can thus theoretically lead to escape from exposure to ticks and to deerfeeding fewer ticks, which lower disease hazard to humans. 2. Combining data on Ixodes ricinus tick abundance with GPS-tracking data of reddeer (Cervus elaphus), we quantified the distributional overlap of ticks and reddeer along elevational gradients in Norway. Furthermore, we correlated bothdeer density and the proportion of migratory deer with the incidence of Lymedisease in humans. 3. We found that migratory deer summer ranges had colder climate and overlappedless with tick distribution than those of resident deer. Deer density consistentlyincreased Lyme disease incidence in humans. However, we found only weak evi-dence that deer migration negatively affected Lyme disease incidence. 4. Our study provides a rare quantification of how host availability, in terms of bothhost density and migratory movement, affects risk of a zoonotic disease.

Abstract

A survey including 3112 responses from individual end users of wood cladding, from Norway, Sweden and Germany, was conducted with questions related to their experience and preferences regarding cladding with and without coatings. Based on these results and established scientific understanding of Service Life Prediction (SLP) of wood cladding, two decision trees were provided to guide end users in selecting a suitable material to meet their expectations when planning a new cladding. This approach makes the users reflect on maintenance requirements and aesthetic changes rather than choosing a product solely based on initial aesthetic appeal.
