contracts have been signed--for example, to de-risk interface problems between the carriers and its aircraft and to deliver the propulsion systems needed to drive what will be the world's biggest all-electric ships.
Occasionally, they held leadership positions, particularly at the suballiance
Ravine forests (European Habitat 9180) belong to the Tilio-Acerion alliance and the Ostryo carpinifoliae-Tilienion platyphylli suballiance
in Greece, although no associations have been distinguished in northern Greece within this suballiance
(Kosir & al., 2008).
However, in the footnote, the authors clearly consider the alliance Batrachion fluitantis Neuhausl 1959 as a suballiance
of their new alliance.

From a syntaxonomical point of view, the presence of species such as Festuca gigantea, Hypericum androsaemum, Senecio nemorensis, Culcita macrocarpa or Woodwardia radicans in these forests allow us to include them in the suballiance
Hyperico androsaemi-Alnenion glutinosae, belonging to the Alnion incanae alliance, Populetalia albae order and Salici-Populetea nigrae class (Table 7, Rivas-Martinez & al., 2002).
A discrimination of beech wood syntaxa based on the soil pH is also maintained for the central Apennines although it is applied only at suballiance
As far as we know, this suballiance
has diversified into some ten associations in the Iberian Peninsula, some of which have been described in the last decade.
The neutrophilous, mesophilous or slightly xerophilous perennial grasslands of subalpine and montane belts belong to the Festuco-Brometea class, the Brometalia-erecti order, the Phleo ambigui-Bromion erecti alliance (endemic to the calcareous Apennines) and the Brachypodenion genuensis suballiance
(subalpine and montane belts of the central-northern Apennines).
