| no impact of pupal predation on the altitudinal distribution of autumnal moth and winter moth (lepidoptera: geometridae) in sub-arctic birch forest. | we tested the hypothesis that pupal predation by shrews underlies the altitudinal distribution pattern of the geometrid moth species operophtera brumata l. (winter moth) and epirrita autumnata bkh (autumnal moth) in a sub-arctic birch forest in northern fennoscandia. in particular, we predicted more intense pupal predation at low altitudes where the two moth species normally do not reach outbreak densities. predation of pupae of both moth species was estimated along 10 parallel altitudinal trans ... | 2009 | 19508770 |
| naturally occurring orthopoxviruses: potential for recombination with vaccine vectors. | orthopoxviruses are being increasingly used as live recombinant vectors for vaccination against numerous infectious diseases in humans, domestic animals, and wildlife. for risk assessments and surveillance, information about the occurrence, distribution and ecology of orthopoxviruses in western europe is important but has mainly been based on serological investigations. we have examined kidneys, lungs, spleens, and livers of norwegian small rodents and common shrews (sorex araneus) for the prese ... | 1998 | 9705389 |
