Demographic Responses and Population Change

Do we need demographic data to forecast population responses to 1 climate change ?

6 Rapid climate change has generated growing interest in forecasts of future population 7 trajectories. Traditional population models, typically built using detailed demographic 8 observations from one study site, can address climate change impacts at one location, but are 9 di cult to scale up to the landscape and regional scales relevant to management decisions. 10 An alternative is to build ...

Adaptive and Demographic Responses of Plankton Populations to Environmental Change

Because of their large population sizes, short generation times, and clonal mode of propagation, microorganisms should often be the first members of a community to respond evolutionarily to temporal changes in the environment. Because the planktonic microbial community directly or indirectly influences all other members of aquatic ecosystems, it is useful to have a general theory for the magnit...

Demographic Sensitivity of Population Change in Northern Bobwhite

The northern bobwhite (Colinus virginianus) is an economically important gamebird that is currently undergoing widespread population declines. Despite considerable research on the population ecology of bobwhites, there have been few attempts to model population dynamics of bobwhites to determine the contributions of different demographic parameters to variance of the finite rate of population c...

Demographic Change and Transport

Cultural innovations and demographic change.

Demography plays a large role in cultural evolution through its effects on the effective rate of innovation. If we assume that useful inventions are rare, then small isolated societies will have low rates of invention. In small populations, complex technology will tend to be lost as a result of random loss or incomplete transmission (the Tasmanian effect). Large populations have more inventors ...
