of biota in northwestern North America. The two major ice age refugia of Beringia and the …

Echinococcosis is a serious helminthic zoonosis in humans, livestock and wildlife. The
pathogenic organisms are members of the genus Echinococcus (Cestoda: Taeniidae). Life …

Intraspecific genetic variation of Echinococcus multilocularis, the etiologic agent of human
alveolar echinococcosis, has been evaluated among 76 geographic isolates from Europe …

Widely distributed taxa provide an opportunity to compare biogeographic responses to
climatic fluctuations on multiple continents and to investigate speciation. We conducted the …

Diversity among assemblages of mammalian hosts and parasites in northern terrestrial
ecosystems was structured by a deep history of biotic and abiotic change that overlies a …

Although surveillance is limited, indigenous residents at latitudes ranging from 53 to 73° N in
Canada appear to have a higher occurrence of infection with some zoonotic parasites than …

Secondary contact zones between deeply divergent, yet interfertile, lineages provide
windows into the speciation process. North American grey foxes (Urocyon …

The phylogeography of four Apodemus species (Apodemus agrarius, Apodemus
peninsulae, Apodemus latronum, and Apodemus draco) was studied in the Far East of Asia …

Red foxes (Vulpes vulpes) are native to boreal and western montane portions of North
America but their origins are unknown in many lowland areas of the United States. Red …

Species that inhabit naturally fragmented environments are expected to be spatially
structured and exhibit reduced genetic diversity at the periphery of their range. Patterns of …
