Within-population dynamics were based on well-understood density-dependent demographic processes (Hassell and Comins 1976).
Age-dependent demographic variables collected at enrolment were converted to age-corrected z-scores according to the WHO Child Growth Standards.
Unequivocal evidence for such interaction-dependent demographic variations was obtained from controlled host-parasite mesocosm experiments, for example with E. coli and its phage [ 10, 30], Hydra hosts and its Hydramoeba parasite [ 43], house fly and its parasitic wasps [ 44, 45], or azuki bean weevil Callosobruchus chinensis and its parasitoid Heteropilus prosopidis[ 46].
Indeed, a climate-dependent-demographic model without dispersion projects that many EP colonies will decline by more than 50% from their current size by 2100, resulting in a dramatic global population decline.
This study investigated the level of trust in NASA in an Australian population sample, and whether this trust was dependent on demographic variables.
This would require that cultural changes were dependent upon demographic changes in this case, and that cattle farming presented a clear advantage to hunting/gathering.
Finally, a generalized linear regression was elaborated to study the relation between costs (dependent variable), demographic and clinical variables (independent variables).
The response rate is known to be dependent on demographic characteristics of the target population and telephone skills of the interviewers [ 5].
We considered perceived stress (stressed cases) as the dependent variable, demographic variables and groups of stressors (i.e. academic, psychosocial and health-related) as the independent variables.
Hierarchical regression analysis was used to explore the associated factor with intrinsic and extrinsic job satisfaction, which was dependent on demographic characteristic, working situation, stress and burnout.
These comparisons denoted that the missing data structure of PM10 exposure levels was dependent on demographic and geographic differences, making extant NHANES III sampling weights not applicable to our analyses.
