"It is not only availability, but also affordability and sometimes capability - seeds are not always suitable for their system or their practices," he told BBC News.
Independent colonizations, plus low capabilities of seed dispersal in current environments, may have resulted in the genetic differentiation between populations of different mountain ranges.
Low capabilities of seed dispersal in current environments, plus possible independent colonization events followed by limited historical gene flow, may have together contributed to the high levels of genetic differentiation between populations of the Yushan Mountain Range and the other mountain ranges (FST = 0.56-0.72).
However, despite their fibril-like appearance, the early metastable amorphous structures do not have the capability to seed fibril formation, which is a clear argument against a possible amyloidic nature.
To evaluate the model's predictive capabilities, it was seeded at the presumed point of initial invasion on the west coast of Ireland in 1908 and then run for 100 timesteps (timesteps = one year).
Thus, among the FTLD-TDP cases we studied here, distinct immunobands of insoluble TDP-43 protein correlate with a distinct seeding activity in vitro, suggesting that different TDP-43 species or strains from FTLD-TDP brains may have different seeding capabilities.
It should be pointed out that our initial intention was to use boiling as a tool to unfold or denature both proteins so as to demonstrate their mineral seeding capabilities in the context of a metastable medium.
In the presence of additional precipitating ions, both γ-irradiated serum (FBS and HS) and γ-irradiated proteins (albumin and fetuin-A) retain the inherent dual NB inhibitory and seeding capabilities seen also with their untreated counterparts.
Another strength is its capability to handle seed node groups, which allows to cope with ambiguous gene-reaction mappings.
To determine if the increased sulphate content in s ultr4;1 seeds, putatively due to a reduced vacuolar efflux capability, has influenced seed composition, seed nitrogen and carbon contents were analysed along with the seed proteome complement.
Indirect methods based on dispersal models indicate dispersal capabilities of orchid seeds by wind of up to 2000 km [ 3]. High levels of LDD will likely reduce the probability that seeds will reach a suitable habitat, as many seeds are 'lost' in the unsuitable matrix between the habitat patches [ 17].
