Examination of ancient sequences in the domestic species might reveal a more complex pre-domestication bottleneck demographic history than the apparent constant population size shown here.
While a simple two-phase growth model is too simplistic to fully describe African population history, it is interesting to note that a more complex model incorporating an ancient bottleneck (i.e., prior to the onset of population growth) does not fit African resequencing data [18], [28].
It is also possible to extend this method to other delegates (e.g. nurse practitioners, medical students, interns and physician assistants) to incorporate breaks and shift length for scheduling or to model more complex decision making to determine bottlenecks in patient flow.
Despite the great success of glycan microarrays using synthetic glycans with defined structures, the bottleneck is the unavailability of more complex glycans.
Such a reduced heterozygosity and lower allele numbers on the islands is in principle in line with the assumption of a colonization bottleneck, but the situation is more complex.
Such a multi-scale model should be considered as a null scenario in testing more complex effects related to habitat fragmentation, such as genetic bottlenecks, or loss of keystone species.
Compared to other microbial cell factories such as Escherichia coli and Saccharomyces cerevisiae, Aspergilli has a far more complex post-translational modification (PTM) system, which is usually regarded as the bottleneck for protein secretion [ 2, 3].
The process required for this is much more complex than the fermentation of simple carbohydrates and one of the bottlenecks is the short supply of biomass-degrading enzymes, such as cellulases.
Overall, it can be seen that the demographic history of C. kanehirae is far more complex than previously thought, with evidence of historical range expansion and a very recent bottleneck (Table 2, Figure 4).
External initiatives focus on "easy" bottlenecks, such as clinical knowledge and warehouse capacity and avoid the more complex issues of systems strengthening [ 67].
