Higher estimates at freshwater entry relative to estimates at natal streams likely reflects mortality among gillnet marked fish during the 2-week interval between river migration and our sampling of populations at natal streams.
NRY and mtDNA simulations were performed as described in the supplementary materials [Additional file 1: Supplemental Section 2], the results of which could be compared to empirical data in order to guide our understanding of the effect migration rate and sample size on genetic structure in the Cross River region.
Only one of the isolates, obtained from a Mistle Thrush (Turdus viscivorus) and sampled during the spring migration 2002, carried Salmonella.
Using theoretical sampling, we drew on previous research, that suggested that age, gender, education and marital status influence post-migration mental health [ 27, 28] and sampled to reflect the diversity across these factors.
The Dutch System of Social Statistical Datasets provides direct access to types of migrants defined by legal status or migration motive, while sampling in Germany has to get along with such distal identifiers as citizenship and place of birth.
However, there may well be a low level ongoing migration which our sampling regime failed to detect.
Statistics Norway obtains updated information on deaths and migration and performs the sampling of women, thereby providing a complete follow-up of participants.
Concentrations of the major ions in leached soil solution were comparatively lower but higher in unsaturated zone water and groundwater, an indication of migration below sampled depths within the unsaturated zone.
RSK1-silencing enhances in vitro cell migration, and human patient samples of metastatic lung cancer have lower RSK1 expression levels compared with non-metastatic cancer tissues [ 49].
When populations are of small size (<500 breeding individuals), a variety of methods, some of which were employed in this study, do exceptionally well in inferring how strong genetic drift was or how large the Ne of the population must be to cause the observed change in allele frequencies over time when assuming no mutation, selection <span class="lh">and migration during the sampled time period [58], [64], [127].
