Pine voles (Microtus pinetorum) and meadow voles (Microtus pennsylvanicus) were studied in a commercial apple orchard in the Hudson Valley of New York during April and May 1981. Selected voles were given miniature radiotransmitters and then tracked before and after herbicide application. A total of eight pine and meadow voles were tracked throughout the experimental period. H0m.e range size dec...

Ce document compare l’état de santé des immigrants et leur utilisation des services de santé à ceux de la population d’origine canadienne à l’aide de données provenant de deux cycles (1985 et 1991) de l’Enquête sociale générale (ESG). Les résultats obtenus démontrent que l’état de santé des immigrants de même que leur utilisation des services de santé ne sont pas significativement différents de...

BACKGROUND French farmers and their families constitute an informative population to study multiple sclerosis (MS) prevalence and related epidemiology. We carried out an ecological study to evaluate the association of MS prevalence and ultraviolet (UV) radiation, a candidate climatologic risk factor. METHODS Mean annual and winter (December-March) UVB irradiation values were systematically co...

Retrospective assessment of pesticide exposure is complex; however, patterns of pesticide use strongly depend on farming type, which is easier to assess than pesticide exposure. Our aim was to estimate Parkinson's disease (PD) prevalence in five French districts in 2007 among affiliates of Mutualité Sociale Agricole (MSA) and to investigate the relation between PD prevalence and farming type. W...

Under natural conditions the vole (Microtus agrestis) breeds in the spring and summer but not in the autumn and winter. This seasonal change was attributed by Baker & Ranson (1933) to the influence of hours of sunshine, and in the laboratory it has been shown that photoperiod affects the growth ofgonads and maintenance of their activity (Baker & Ranson, 1932; Clarke & Kennedy, 1967; Breed & Cla...

Paternal and nonpaternal voles (microtus) have different arginine-vasopressin (AVP) and oxytocin (OT) receptor patterns in the extended amygdala, a neural pathway associated with parental behavior. Using receptor autoradiography, the authors examined whether AVP and OT receptor patterns were associated with facultative paternal behavior in either sexually and parentally inexperienced or experie...

The complete genome sequence of Muju virus was determined from lung tissue samples of three royal voles (Myodes regulus) captured in Gangwon province in the Republic of Korea. Since few whole genome sequences of hantaviruses are available, this sequence may help to clarify the molecular phylogeny of arvicolid rodent-borne hantaviruses.
