The construction work is causing bottlenecks in the city centre.
Is there any way of getting around this bureaucratic bottleneck?
2 a problem that delays a process or stops it from continuing:
Mating system, bottlenecks and genetic polymorphism in hermaphroditic animals.
Increased heritable variation following population bottlenecks : the role of dominance.
Description and power analysis of two tests for detecting recent population bottlenecks from allele frequency data.
Repeated population bottlenecks lead to losses in genetic variation because of random genetic drift.
The combination of paternal bottlenecks and correlated paternity increases the genetic identity of progeny across families and predisposes populations to biparental inbreeding in subsequent generations.
Unless direct evidence for bottlenecks is obtained, or the alternative interpretations ruled out, this issue is unresolved.
Strong bottlenecks cause phylogenies to have shorter external and longer internal branches.
As a result, bottlenecks in the retrieval process could well lead to an underestimation of true storage capacity.
