These observations predict a more complex interplay between signalling mechanisms for the regulation of cellular growth at different population densities.
An important question for future research is how different phenotypes relate to CNVs occurring at different population frequencies.
These findings highlight the important role that the existence of multiple Allee or positive density dependent effects acting at different population life history stages, and importantly their interactions, can play in the population dynamics and management of populations [23].
Additional Southern analysis of several independent S2 and control LCLs at different population doublings showed that the telomeres in the S2 LCLs were severely short and continued to shorten with cell divisions.
The standardized effect sizes [29] were calculated for the behavioral responses to allow us to compare the effects of the NHV components (for the prey) on laboratory and field responses in the clerid as well as to compare the response in the two field tests that were run at different population levels.
To confirm this finding, we serially subcultured NHKs until they senesced (Fig. 1A), and cells at different population doublings were harvested and subjected to Western blotting.

Second, the paper considers various pricing strategies and argues that intra-country price discrimination – charging different prices for similar products targeted at different populations in the same market – can be an effective way of distributing lifesaving drugs to poor communities in countries that have both rich and poor populations.
These look at different populations who naturally have different levels of UV exposure due to factors such as geography or lifestyle.
"My view is that [both] were right and they were addressing different questions". For one thing, the randomized studies on hormone replacement and vitamin E that Ioannidis cited in his 2005 paper looked at different populations than the observational studies they refuted, says Stampfer, who takes vitamin E himself.
The studies considered here were heterogeneous in that they looked at different populations, with one study looking at women only.
Studies looking at different populations in terms of age and gender and carried out at different times will thus arrive at different prevalence estimates for these reasons alone.
