The paper develops a nonlinear feedback model to assess selection pressures on kin effects in human populations, finding negative sensitivity of fitness metrics to kin presence on child mortality.

The paper develops a demographic model to calculate lifetime kin overlap, showing how mortality and fertility affect kin interactions across generations.

The paper extends variance partitioning analysis to multiple factors and their interactions in heterogeneous populations, demonstrating that stochastic processes contribute more to variance in longevity than heterogeneity.

The paper develops a stochastic kinship model to project variances and covariances of kin age-stage distributions, improving upon deterministic models by incorporating demographic stochasticity.

The paper develops a framework linking kin interactions to population dynamics in African elephants, showing how family structure affects survival and reproduction under poaching pressure.
