Примери за vole

• In contrast to small rodents such as wood mice and voles, and perhaps surprisingly, larger rodents such as rats have been relatively neglected by helminthologists.

• However, the infectivity of voles was much higher than that of mice.

• It is therefore extremely unlikely that there was any systematic difference between the voles in our treatment groups.

• Quantitative associations were confined to the 2 vole species in the study.

• In total, 109 (19 %) bank voles and 12 (8 %) wood mice were infected.

• Since infected voles survive for several months, some of the voles trapped were probably infected before or shortly after the beginning of baiting.

• All voles were culled and weighed, and blood smears prepared from blood taken from the heart.

• Also, the massive infection can disturb the locomotion and escape ability of the voles making them more susceptible to predation by arctic foxes.

• There is a good deal of indirect evidence that some species, notably voles, go through regular cycles of this kind.

• At dissection of voles, body weight and length were recorded.

• Sixty-two voles were found to be positive with alveolar infection (infection rate at 5 %).

• Lengths of infected female voles ranged from about 112 to 167 mm, and from 106 to 174 mm for males.

• Lower prevalence in voles might be an indication of the latter.

• As previously, voles at site 1 also showed greater hind foot asymmetry.

• The frequency with which voles were infested by mites was higher in baited blocks.
