| leptographium tereforme sp. nov. and other ophiostomatales isolated from the root-feeding bark beetle hylurgus ligniperda in california. | the redhaired pine bark beetle hylurgus ligniperda (f.) is native to europe but was discovered in los angeles, california, in 2003. this root-and stump-feeding beetle is a common vector of ophiostomatales, which are potential tree pathogens or causes of blue stain of conifer sapwood. in this study ophiostomatales were isolated on a cycloheximide-amended medium from 118 adult h. ligniperda collected from infested logs of pinus halepensis and p. pinea at two sites in california. in total eight spe ... | 2010 | 20943533 |
| epitypification of ophiostoma galeiforme and phylogeny of species in the o. galeiforme complex. | ophiostoma galeiforme was described first in 1951 from larix kaempferi in scotland, where it was found to be associated with the bark beetles hy-lurgops palliatus, dryocoetes autographus, and the ambrosia beetle trypodendron lineatum. the taxonomy of this fungus has been uncertain because of a lack of sexual structures on the type specimen and contamination of a preserved ex-type culture. the aim of this study was to clarify application of the species name, o. galeiforme, by designating an epity ... | 2004 | 21148954 |
| high-resolution dna melt-curve analysis for cost-effective mass screening of pairwise species interactions. | ecological studies of pairwise interactions are constrained by the methods available for rapid species identification of the interacting organisms. the resolution of data required to characterize species interaction networks at multiple spatio-temporal scales can be intensive, and therefore laborious and costly to collect. we explore the utility of high-resolution dna melt-curve analysis (hrm) as a rapid species identification method. an approach was developed to identify organisms at the pairwi ... | 2013 | 23875939 |
