Bird & Mammal Populations

Population dynamic life histories of the birds & mammals of the world

Explore the life history traits and population dynamics of the birds and mammals of the world.

16,123 species & 3849 populations

Reconciling data, theory & estimates by a few axis of natural selection.

The life history covariance among species is decomposed & extrapolated by allometric theory & ecological selection.

Download model estimates of the demography, individual growth, energetics, population ecology, and population dynamics.

Make your own population simulations using the Population Dynamic Simulator.

Time-series data extend the life history models into population dynamic projections; extrapolating models across species.

Selection regulation is estimated stronger than density regulation, explaining cyclic dynamics in birds & mammals.

Scope, methods, uncertainty, and sources.

Data are incomplete or missing for most species. But Bird & Mammal Populations fill the gap; integrating data and natural selection theory into life history estimates and population dynamic simulations, covering the birds & mammals of the world.
