| dna evidence that marshallagia marshalli ransom, 1907 and m. occidentalis ransom, 1907 (nematoda: ostertagiinae) from svalbard reindeer are conspecific. | the gastro-intestinal parasitic nematodes of ruminants marshallagia marshalli and m. occidentalis are morphs of a single species according to indirect evidence. in this study, their taxonomic status and molecular identification were assessed more directly in isolates from the abomasal nematode community of svalbard reindeer using genetic data. dna sequences of the first and second internal transcribed spacers of nuclear ribosomal rna genes were obtained from individual nematodes by the polymeras ... | 2001 | 11586078 |
| resistance to abomasal nematodes and individual genetic variability in reindeer. | resistance to parasites is believed to have a widespread influence on demographic and adaptive processes. in systems where parasites impose a fitness cost on their host, heterozygotes may be selected because they are more resistant to parasites than homozygotes. our objective was to assess the relationships between genomewide individual heterozygosity and abomasal nematode burdens in female svalbard reindeer (rangifer tarandus platyrhynchus) after the effects of host age, locality, season, and y ... | 2005 | 16262866 |
