It is well known that root restriction or pruning can influence scion vigour and the root:shoot ratio (Richards and Rowe, 1977; Ferree, 1992; Williamson et al., 1992).
It is well known that rooting a tree of Zaire ebolaviruses using any distantly related ebolavirus is problematic in the sense that the branching pattern of Zaire ebolaviruses differs depending on the deriving features; for example, using coding gene sequences versus intergenic sequences changes the molecular evolution story of the current outbreaks (Dudas and Rambaut 2014).
Deep root systems are also common among the trees with some taxa, such as Eucalyptus and Prosopis being well known for having root systems that reach depths of 10 20 m or more (Canadell et al. 1996; Schenk and Jackson 2002 a, b ; Stromberg 2013).
It is well known that the root distribution of A. ordosica is shallower than that of S. psammophila and P. simonii, and that land with A. ordosica was covered by soil biological crusts.
Cambridge is well known for its roots in hard tech such as biotechnology and engineering; its cluster currently houses 1,535 companies; 12 tech companies in Cambridge have achieved $1bn£642m2m) valuations in the past 15 years, and the combined turnover of the entire cluster was recorded at £11.8bn in 2011.
It is well known that the roots are the main route through which Pb enters plants [ 10], and about 90% of Pb is accumulated in roots of some plants [ 11].
It is also well known that the roots and extract of L. platyphylla contain a wide variety of constituents, although more analyses are needed to verify the correlation between their functions and therapeutic effects.
The THANKS principle is well known and deeply rooted in Ojibway natural resource harvesting and management as an important means of acknowledging relationships to the beings that sustain individuals in their daily life (Densmore 1928).
As is well known, the unprocessed Aconite root, if ingested, causes fatal toxicities [9 11].
Perugia may not be as well known for its Etruscan roots as other central Italian towns, but traces of its pre-Christian past are everywhere.
While the habitat value of treefall pits for plants is relatively well known, the characteristic exposed root-plates of treefall mounds, which may require different management, have received less attention.
