Hence, follow up studies in Switzerland should include, in addition to surveillance for neonatal herpes, a repeated population-based study to assess any temporal trend in HSV seroprevalence.
The MZIMA study is a repeated population-based household survey, involving a representative cohort of persons aged 15 years and older from the Ifakara region.
The Tromsø Study has a design which includes repeated population health surveys to which total birth cohorts and random samples are invited.
As a result of passing through repeated population bottlenecks, in which only a handful of individuals survived to spawn subsequent generations, today's 100,000 musk oxen are thought to be notably homogenous, lacking in the sort of genetic diversity once thought critical to a species' long-term prospects.
It has been predicted that populations occurring in marginal habitats may be more vulnerable to repeated population crashes which can also result in a significant reduction in genetic diversity (Cozzolino et al. 2003), which may be the case in many orchids of Madagascar where only a few individuals are left in the wild.
Random genetic drift due to repeated population crashes during the overwintering phase led to fixation of a single fungal genotype (in terms of its virulence), often within 100 seasons.
Further forest monitoring including repeated population assessments is needed to evaluate the vulnerability of threatened tree species.
Insecurity in the east of the country, including Katanga, causes repeated population displacements.
Cyclic populations are model systems for this purpose, showing clear and repeated population trajectories, despite stochasticity.
Nearly all simulated fungal populations became fixed within 100 seasons, probably due to genetic drift arising from repeated population crashes.
The design includes repeated population health surveys to which total birth cohorts and random samples are invited.
