Interactions among soil biota in coniferous ecosystems
(Elsevier, 1988-11)
The dominance of ectomycorrhizae in most coniferous forest ecosystems profoundly alters the classical concept of the role of exudation and rhizodeposition of cell fragments in the formation of the rhizosphere. In the ...
Despite introgressive hybridization, North American birches (Betula spp.) maintain strong differentiation at nuclear microsatellite loci
(Springer-Verlag, 2015-09-18)
Extensive chloroplast introgression has been documented in polyploid Betula species of eastern North America. However, the extent to which the nuclear genomes of these species are differentiated is unknown. Therefore, we ...
