The samples of trabecular tissue were therefore analysed 'as found', which in some cases included invaded soil.
A. artemisiifolia biomass was 50-130% greater when competing with three co-occurring plants, compared to single-species competition only (invasion by A. artemisiifolia alone), in heavily invaded soil.
There is no question that the trabecular tissues are at all times augmented by decomposed soft tissue collapsing onto the bone lamellae, and occasionally polluted by invading soil, as will be abundantly clear in the results section of this paper.
It is evident that the material least exposed to groundwater contamination is the teeth and the compact bone tissue, while the pars petrosa and the trabecular bone tissue, which is much harder to decontaminate and much more exposed to contamination by percolating ground water and invading soil particles, are more exposed to diagenesis.
Moss protonemata, branched chains of cells invading soil or growth medium in an almost mycelium-like fashion, can therefore serve as another interesting model system for the study of plant cell invasiveness.
Overall, net nitrification and mineralization generally decreased in the invaded soils.
The lower NO3− availability of invaded soils could explain their lower DNRA rates (0.04 0.70 ×) compared to native soils.
Both invaded areas accumulated higher litter densities with greater N contents and lower C/N ratios than the native areas, which corresponded to lower C/N ratio and to higher potential rates of nitrification in the invaded soils.
Correspondence analyses (CA) for both RGs revealed closer relationships among North American AMF taxa than between North American and Kashmir AMF, from either control or invaded soils (Figure 2).
In other words, more similarity between AMF species of control vs. invaded soils in the non-native region, in comparison with native region samples, was brought out by the correspondence analyses of RGs (Figure 2).
