Averaging population density [PDF]

Demography, 1984
Abstract Population density is a commonly quoted statistic. Almost no general descriptive summary of the population of an area is complete without a density listing, table or map. As each such density statistic is an average, it is worth considering what kind of average is being used. This article analyzes this and illustrates the effect

Linking individual phenotype to density-dependent population growth: the influence of body size on the population dynamics of malaria vectors [PDF]

, 2011
Understanding the endogenous factors that drive the population dynamics of malaria mosquitoes will facilitate more accurate predictions about vector control effectiveness and our ability to destabilize the growth of either low- or high-density insect ...

Experimental evidence for density dependent reproduction in a cooperatively breeding passerine [PDF]

, 2009
Temporal variation in survival, fecundity, and dispersal rates is associated with density-dependent and density-independent processes. Stable natural populations are expected to be regulated by density-dependent factors.

Estimating the functional form for the density dependence from life history data [PDF]

, 2008
Two contrasting approaches to the analysis of population dynamics are currently popular: demographic approaches where the associations between demographic rates and statistics summarizing the population dynamics are identified; and time series approaches

Consequences of Population Density and Size [PDF]

Urban Affairs Quarterly, 1980
The classical theory about effects of high residential density is "negative," stating that high density produces negative social attitudes and undesirable behaviors. Yet empirical re search usually finds density only weakly related to individuals' attitudes and behavior.
