Density dependence shapes life-history trade-offs in a food limited ungulate population

This study shows density dependence shapes life-history trade-offs and reproductive success distribution in Soay sheep populations.

Transient dynamics and nonlinear fitness: a unified matrix approach to press and pulse perturbation

The paper develops a unified matrix framework to analyze both pulse and press disturbances in populations, showing how transient dynamics influence long-term fitness and demographic responses.

Structured demographic buffering: A framework to explore the environment drivers and demographic mechanisms underlying demographic buffering

The paper introduces a framework to quantify the effects of environmental factors, population structure, and demographic rates on demographic buffering in plant species.

Temporal variability can promote migration between habitats

The paper shows that environmental variability can increase stochastic growth rate through migration between sites, even when one site is on average the best.

Life-history dynamics: damping time, demographic dispersion and generation time

The paper analyzes damping time across 600+ species and finds it scales with generation time, independent of demographic dispersion, suggesting slow life-history species are more vulnerable to disturbances.
