Can microhabitat use explain individual differences in tick parasitism in coexisting wood mice (Apodemus sylvaticus), bank voles (Myodes glareolus) and common shrews (Sorex araneus)?

The sheep tick (Ixodes. ricinus) is a major vector of a variety of zoonoses in Europe. This tick species are an ecological generalist, feeding on a variety of hosts. Small mammals are important hosts of juvenile stages (larvae and nymphs) and play an important role in the transmission of such illnesses to humans. Ticks are often heterogeneous distributed between hosts; while some hosts carry no parasites, others carry many. This aggregation of vectors increases the rate of disease spread in a population, and individuals or species hosting large tick burdens therefore play a very important role in the transmission mechanism of tick-borne diseases. Several studies from continental Europe and the Great Britain has shown that the yellow-necked mouse (Apodemus flavicollis) and the wood mouse (A. sylvaticus) carry more ticks than the bank vole (Myodes glareolus), but these studies lack the ability to explain the large interindividual heterogeneity in tick burden across host species. Larvae and nymphs of the sheep tick are vulnerable to high temperatures and low humidity, and their spatial distribution are therefore indirectly governed by vegetation characteristics. The spatial distribution of small mammal hosts are also highly affected by habitat type, and this suggests that the microhabitat use of coexisting small mammals can influence their tick burden.
Here I present a study where I test the relationship between individual microhabitat use of small mammals and their tick burden. The study was carried out in a heterogeneous woodland landscape located in Southern Norway. Live trapping of small mammals in high spatial resolution was carried out during four trap sessions throughout 2010. At each trap location, habitat characteristics were examined and abundance of questing ticks were recorded by standard blanket dragging during each of the four trap sessions.
Abundance of both host-seeking larva and nymphs were significantly higher in sites where the ground were covered with leaf litter, and where heath of the Vaccinium genus were scarce. There were significant differences in microhabitat use between the small mammal as well; Bank voles were trapped in areas with more leaf litter and more Vaccinium heath than common shrews, while wood mice shoved an intermediate pattern. Contrary to most other studies of tick burden on small mammals, no significant differences in burden between host species could be detected, but males had a significantly higher larval burden than females. However, regardless of sex or species, individuals trapped in sites with much leaf litter (where the highest density of host-seeking tick larva were observed) had a significantly higher larval burden than individuals trapped in sites with minor amounts of leaf litter.
These results suggest that the commonly observed heterogeneity in tick burden across host species might be due to individual differences in microhabitat use. The capacity to reduce the spread of tick-borne pathogens rests on the ability to successfully detect individuals that hosts disproportionately large numbers of ticks. This study suggests that individual space use characteristics effect this pattern. Further studies are needed to investigate whether individual microhabitat use and tick burden levels are constant over time or whether they change throughout the season.
