Taxon‐ and vector‐specific variation in species richness and abundance during the transport stage of biological invasionsNARA Subscribed
Recent empirical and statistical evidence suggest that propagule pressure (i.e., number of individuals introduced per event, and the number and frequency of events) and colonization pressure (i.e., number of species released per event, and the number and frequency of events) are of vital importance to invasion success. To explore possible changes in propagule and colonization pressure during the transport stage of the invasion...
Vertical partitioning between sister species of R hizopogon fungi on mesic and xeric sites in an interior D ouglas‐fir forestNARA Subscribed
Understanding ectomycorrhizal fungal ( EMF ) community structure is limited by a lack of taxonomic resolution and autecological information. R hizopogon vesiculosus and R hizopogon vinicolor ( B asidiomycota) are morphologically and genetically related species. They are dominant members of interior D ouglas‐fir ( P seudotsuga menziesii var . glauca ) EMF communities, but mechanisms leading to their coexistence are unknown. We...
Do escaped transgenes persist in nature? The case of an herbicide resistance transgene in a weedy Brassica rapa populationNARA Subscribed
The existence of transgenic hybrids resulting from transgene escape from genetically modified (GM) crops to wild or weedy relatives is well documented but the fate of the transgene over time in recipient wild species populations is still relatively unknown. This is the first report of the persistence and apparent introgression, i.e. stable incorporation of genes from one differentiated gene pool into another, of an herbicide r...
