| on the mtdna restriction patterns variation of the iberian wood mouse (apodemus sylvaticus). comparison with other west mediterranean populations. | in previous studies, the presence of three main lineages of wood mice mtdna was described in western europe: a first one distributed from the pyrenees to scandinavia. a thyrrenian one occurring in peninsular italy, elba, corsica and sardinia and a third one restricted to sicily and marettimo. do the iberian wood mice belong to one of these lineages? in order to answer this question, animals were trapped all over the iberian peninsula (11 sites) as well as in three of the balearic islands. compar ... | 1998 | 10319716 |
| patterns in size and shedding of fasciola hepatica eggs by naturally and experimentally infected murid rodents. | using samples collected on the island of corsica, a comparative study was done of the morphometry of fasciola hepatica eggs shed by cattle and by naturally and experimentally infected murid rodents (wild mus musculus and rattus rattus and rattus norvegicus wistar laboratory strain). eggs shed by murids are smaller in size than those shed by naturally infected cattle. a second study analyzed the number of f. hepatica eggs shed in murid feces at different time intervals, i.e., months, days, and 6- ... | 2002 | 12054003 |
| mites as biological tags of their hosts. | movements and spatial distribution of host populations are expected to shape the genetic structure of their parasite populations. comparing the genetic patterns of both interacting species may improve our understanding of their evolutionary history. moreover, genetic analyses of parasites with horizontal transmission may serve as indicators of historical events or current demographic processes that are not apparent in the genetic signature of their hosts. here, we compared mitochondrial variatio ... | 2010 | 20546134 |
