seasonal and age distributions of babesia, hepatozoon, trypanosoma and grahamella species in clethrionomys glareolus and apodemus sylvaticus populations.four common blood parasites belonging to the genera babesia, hepatozoon, trypanosoma and grahamella were detected in sympatric populations of clethrionomys glareolus and apodemus sylvaticus. seasonal changes in the abundance of hosts and parasites were monitored in a longitudinal field survey for 18 months. all parasites in both hosts showed similar seasonal patterns with most transmission occurring in summer and autumn and ceasing in winter. amongst aged subsets of each host population, hepatoz ...19863537923
rodents as seed dispersers in a heath - oak wood succession.in a danish heathland invasion of oak shrub has taken place, the succession rate being approximately 300 m during the last 100 years. the colonisation has occurred in steps related to the delay time between seedling stage and fertility stage. seedlings are often found in clusters originating from caches probably made by seed-eating rodents. apodemus sylvaticus, a. flavicollis and clethrionomys glareoles. these rodents reached autumn densities of 25-50 individuals per ha. radioactive acorns were ...198628311660
changes in home range size during growth and maturation of the wood mouse (apodemus sylvaticus) and the bank vole (clethrionomys glareolus).a field study was carried out during winter and spring of 1982/83 to determine changes in home range size with increasing body weight and maturation in the wood mouse (apodemus sylvaticus) and the bank vole (clethrionomys glareolus). individual home range sizes in males increased and in females decreased with increasing body weight. relating these changes to changed energetic requirements failed. in these species behavioral aspects seem to be a more important determinant of home range size than ...198628311723
possible use of environmental gradients in orientation by homing wood mice, apodemus sylvaticus.51 wood mice, apodemus sylvaticus, tagged with chemoluminescent bulbs, were visually tracked in a series of night homing experiments. the mice did not go straight towards home, but wandered around the release area and covered distances equal to twice the radial lengths recorded. in the course of their walk, they orientated preferentially towards landscapes which resembled their usual habitat, irrespective of where their actual homeward direction lay. in spite of the randomness of their paths, ho ...198724925488
the harderian gland, its secretory duct and porphyrin content in the woodmouse (apodemus sylvaticus).the harderian gland of the woodmouse (apodemus sylvaticus) consists of tubules lined by a single layer of epithelial cells with a surrounding layer of myoepithelial cells. the epithelium contains two cell types, one with numerous small, clear, lipid vacuoles (type i), the other with large electron-dense ones (type ii). each type is further subdivided into cells where the smooth endoplasmic reticulum exhibits pronounced vacuolation (ia and iia). the lipid vacuoles frequently coalesce and are rele ...19873429316
developpement de la locomotion chez le mulot sylvestre (apodemus sylvaticus l.).this longitudinal study describes the functional development of locomotion in the woodmouse, apodemus sylvaticus . it shows that postnatal day (pnd) 11 is a critical age in the acquisition of independence. locomotion develops in successive stages before reaching the adult pattern (walking) at pnd 11. intermediate patterns are determined by the degree of coordination between the different parts of the body. some of these patterns overlap and do not necessarily appear in every individual in our ex ...198724897260
asymmetry in the hippocampal region specific for one of two closely related species of wild mice.the volumes of the components of the left and right hippocampal regions were compared in male, adult specimens of the two closely related species of wild mice, apodemus flavicollis (yellow-necked wood mice) and apodemus sylvaticus (long-tailed wood mice). in one of the species, apodemus flavicollis, the component containing the deep layers of the subiculum was found to be significantly larger in the hippocampal region of the left side than it was in that of the right side. no other significant a ...19873690355
avian predation upon a mixed community of common voles (microtus arvalis) and wood mice (apodemus sylvaticus).pellets of diurnal avian predators (mainly kestrels and buzzards) were analysed to prove the hypothesis of selective predation for a mixed population of small rodents. it was found that voles heavily predominated as prey over mice (up to a factor of 19 during winter). within both prey species, predation focussed on distinct parts of the populations: during winter the heaviest specimens were preferentially captured, during summer the subadults were in an exposed position. in the voles, an additio ...198828312695
