Abstract The bank vole (Clethrionomys glareolus) is the natural reservoir of Puumala virus (PUUV), a species in genus Hantavirus. PUUV etiologic agent nephropathia epidemica, mild form hemorrhagic fever with renal syndrome. Factors that influence hantavirus transmission within host populations are not well understood. We evaluated number factors influencing on association increased infection voles captured region northern Sweden endemic for virus. Logistic regression showed four together...
The relative palatabilities of nine plant taxa used as winter food by reindeer were estimated presenting them in cafeteria and pairwise tests Feeding p reference indices then related to the chemical composition plants High preference obtained for lichens Bryoria spp, Cladina arbuscula, C rangiferina stellaris, while low values moss Pleurozium schrebel dwarf shrubs Empetrum hermaphroditum Vaccinium myrttllus grass Deschampsia flexuosa lichen Stereocaulon paschale received intermediate scores...
The prevalent human hantavirus disease in Sweden is nephropathia epidemica, which caused by Puumala virus and shed infected bank voles (Clethrionomys glareolus). To evaluate temporal spatial patterns of this disease, we studied 2,468 reported cases from a highly disease-endemic region northern Sweden. We found that, particular, middle-aged men living rural dwellings near coastal areas were overrepresented. case-patients most often late autumn, when engaged activities or within manmade rodent...
Mammalian herbivores of the boreal forest face, apart from large seasonal changes in forage quality and quantity, also problems selecting appropriate plant parts. Winter is characterized by forages low digestibility nutrients, but high fiber chemical defenses. Distribution these characteristics varies with twig thickness. For birch declined increased diameter. A similar pattern found for total phenols phenolic glucoside platyphylloside. On other hand, concentration thickness
Transdisciplinary research and collaboration is widely acknowledged as a critical success factor for solution-oriented approaches that can tackle complex sustainability challenges, such biodiversity loss, pollution, climate-related hazards. In this context, city governments' engagement in transdisciplinarity generally seen key condition societal transformation towards sustainability. However, empirical evidence rare. This paper presents self-assessment of joint project on ecosystem services...
In two field experiments the feeding preference of voles (Microtus agrestis and Clethrionomys glareolus) hares (Lepus timidus), offered winter dormant shoots/branches three deciduous tree species, were determined related to nutritional quality concentration phenolics. Both consumed more rowan (Sorbus aucuparia)/aspen (Populus tremula) (vole hare experiment, respectively) than birch in patches containing (Betula pubescens) together with rowan/aspen slightly but not significantly alder (Alnus...
While ecosystem-based planning approaches are increasingly promoted through international and national policies, municipalities still struggling with translating them into practice. Against this background, paper aims to increase the knowledge of current advances possible ways support implementation ecosystem services (ES) approach at municipal level. More specifically, we analyze how ES have been integrated comprehensive within municipality Malmö in Sweden over last 60 years, a declared...
Tick-borne encephalitis (TBE) is a human disease caused by flavivirus that spread ticks (Ixodes ricinus). In 2011 and 2012, the highest TBE incidence ever was recorded in Sweden. It has been proposed warmer spring temperatures result higher survival of thus high TBE. Here, analyses were done time series for 1976–2011 relation to North Atlantic Oscillation (NAO), mean summer temperatures, yearly number harvested European hare (Lepus europeaus), roe deer (Capreolus capreolus), red fox (Vulpes...
Usnic acid, a common secondary metabolite in prefered lichens by reindeer and caribou, has been tested for its effect on In Vitro Dry Matter Digestibility (IVDMD) using inocula from four reindeer. When Cladonia alpestris (stellaris (OpicJ) was used as substrate rumen liqour media of incubation together with usnic digestibility considerably enhanced. This also true lower lichen Stereocaulon paschale (L.), but the less pronounced. The results suggest that host some microorganism able to...
Abstract The theory of plant defences proposes that investments in physical and chemical are driven by the risk herbivore damage, limited cost producing particular defensive trait terms resources could be directed to other sinks, such as growth reproduction. We sampled twigs 18 mature Acacia tortilis trees their cohort juveniles test some predictions this hypothesis. expected a higher allocation traits leaves young plants than ones result damage ungulates at juvenile stage. Our results show...
Puumala virus, genus Hantavirus, is the etiologic agent of nephropathia epidemica, a mild form hemorrhagic fever with renal syndrome. The bank vole (Clethrionomys glareolus) natural reservoir species this hantavirus. We initiated sampling voles at sites recently identified human epidemica cases and paired control in fall 1995 coastal areas northern Sweden. Sites were trapped annually spring until 1999. Prevalence antibody to virus was similar among local populations two types over time....
Time series analysis was performed on two data of human nephropathia epidemica (NE) infections in northern Sweden between the years 1959-1975 and 1985-2006. The confirms that bank vole (Myodes glareolus), main reservoir species, shows regular peaks population density approximately every fourth year. periodicity NE cases more recent time period (1985-2006) is 2.8-3.3 older a ranging 3.4-4.2 years, but this not significantly different from expected by dynamics. A comparison North Atlantic...
Abstract Several hypotheses relate a negative relationship between foliar concentration of phenolic compounds and nitrogen to physiological processes such as leaf development, seasonal variation in allocation priorities, nutrient, light water related growth limitation, well herbivore attack. We sampled four common deciduous woody species central Tanzania monthly during the growing season assess changes this relation their nutritional value ruminants. found N within among sites that weakens...

Catch per unit effort (CPUE) is used as a standardized trapping method by local fishermen and in monitoring studies. In this study, CPUE was compared with population estimates made capture-recapture based on the passive integrated transponder (PIT-tag) marking of individuals.
