the effect of diet quality on gut anatomy in british voles (microtinae).three species of british voles, the bank vole clethrionomys glareolus, the field vole microtus agrestis and the water vole arvicola terrestris were maintained on diets of seed and plant leaf material to investigate changes in gut anatomy. c. glareolus and m. agrestis showed significant changes in most regions of the gut; they developed longer and heavier tracts when on a high-fibre diet. this response may be important in enabling these animals to withstand seasonal changes in diet quality.19938408846

investigations on a swiss area highly endemic for echinococcus multilocularis.anecdotal information suggested that a focus of hyperendemicity may be present in a small area of the canton of fribourg in switzerland. therefore, the prevalence of e. multilocularis was assessed both in the fox and the rodent population over a two-season-period. a high prevalence ranging between 47% and 56% was consistently determined in the fox population. an arvicola terrestris population was infected at 39% in the first season of investigation and at 11% in the following season. a subsequen ...19968688861
