This paper introduces S-elasticity, a second-order elasticity measure to analyze nonlinear fitness responses to vital rate perturbations in ecology and evolution.

The paper uses stochastic simulations of population models to show life history traits predict how population structure influences population growth rate under environmental variability.

The paper examines the impact of increasing wild ungulate density on snow leopard predation of livestock in the Trans-Himalaya, finding apparent competition rather than facilitation.

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.

This study uses long-term guppy population data to show stochasticity alters population stability and resilience through noise-induced bifurcations and ecological differences.

The paper examines the ecological and genetic resilience of traditional crops in the Indian Trans Himalaya, finding they are better adapted to local conditions and have greater genetic diversity than introduced crops.

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