Diversity and distribution of the
pedunculate barnacle Octolasmis in the seas adjacent to Singapore.
To observe more precisely the relationship between the triterpenoids composition and the botanical species, the mean concentration of the quantified compounds were calculated for sessile (n = 27) and
pedunculate (n = 19) oak samples (see "Mean Concentrations of QTT I,
Similar findings elsewhere reinforce the view that inter-tree competition can increase the mortality risk and may thus act as a significant agent behind the decline and death of climate-stressed
pedunculate oaks (Rozas & Garcia-Gonzalez, 2012).
The experimental duration was based on similar experiments conducted in other
pedunculate barnacles (Yusa et al., 2013; Yamaguchi et al., 2014), and was sufficient for newly settled individuals to become mature as dwarf males in this species.
Outside the range of the beech,
pedunculate oak becomes the most important tree in the habitats of G.
Cercetari privind regenerarea naturala a gorunului si stejarului pedunculat in padurile de sleau de deal din Podisul Tarnavelor (Research on natural regeneration of sessile oak and
pedunculate oak in mixed oak-dominated stands of Tarnavelor Hills).
Flowers closely disposed, initially subsessile, then
pedunculate; pedicles 1-2 mm long.
The phase space of diameter growth for
pedunculate oak [[phi].sub.d] = 0.001, crown expansion [[phi].sub.D] = 0.027, and the phase space of height structure [[phi].sub.h] = 0.876.
It is the objective of this study to estimate the rate of hybridization between sessile and
pedunculate oak in a mixed stand using two complementary approaches.
1) differs from that of typical
pedunculate barnacles like Lepas spp.
