title: Stage-structure models of populations with distinct growth and development processes.
abstract: We extend the repertoire of stage-structure models which can be described in terms of delay-differential equations, by analysing models where the processes of growth and development within a stage are distinct. This permits the use of delay-differential equation models in situations where both population numbers and total biomass are dynamically significant.
