The phrase "population age structure" is correct and usable in written English.
You can use it to refer to the distribution of different age groups within a population. For example, "The population age structure of the city has changed significantly over the past two decades."
These findings significantly change the perception of population age structure in forest remnants of Mediterranean landscapes.
The knowledge of the age of individual trees and of population age structure is of great importance for conservation purposes.
The length-conditional method uses the underlying population age structure to derive predictions and therefore has been limited to implementation inside the stock assessment model.
In this study, we instead use an "approximate length-conditional" approach, which assumes that each fish is a random sample from that length bin based on an equilibrium population age structure, to fit age-length data from three previous studies.
This paper used simulation methods to evaluate the estimates of the von Bertalanffy growth parameters outside the assessment model using the traditional method and a length-conditional method based on an equilibrium approximation to the population age structure derived from an estimate of the total mortality rate.
To provide fundamental decision support information for climate risk assessment in Hungary, an urban spatial development model of land cover change and population age structure dynamics was developed and applied to local integrated scenarios of climate change and stakeholder-derived socio-economic change.
Through the simulation of scenarios for varying fertility rates, the paper explores and quantifies the impacts of ageing and population age-structure changes on travel patterns in the census metropolitan area (CMA) of Hamilton in Ontario, Canada.
After calibrating methods with known-age birds, long-term monitoring of population age-structure could potentially be achieved using telomeres [42], [43] (but see [44]).
If the declines emerged as a result of age-dependent clutch size and productivity coupled with a shifting population age-structure, neither measure may be particularly amenable to management and there may be less concern about an ongoing recovery.
Despite extensive banding at some breeding sites, there is no published information on age-dependent reproduction in California least tern and there are few estimates of population age-structure.
Long-term declines in clutch size and fledgling productivity may reflect: 1) reduced food availability, 2) increased density-dependent competition, and/or 3) age-dependent reproduction coupled with a shifting population age-structure.
