Biological and statistical interpretation of size-at-age, mixed-effects models of growth

The paper develops mixed-effects models of growth functions to estimate individual and group variation in body growth using freshwater fish data.

Estimates of vital rates and predictions of population dynamics change along a long-term monitoring program

The paper shows that estimates of survival and growth stabilize with limited data, while density predictions stabilize after 5 years of monitoring in freshwater fish populations.

Stronger effects of heterozygosity on survival in harsherenvironments

The study investigates how heterozygosity affects survival in marble trout populations under varying environmental conditions, finding stronger effects in low-survival populations and post-flood births.

A framework for estimating the determinants of spatial and temporal variation in vital rates and inferring the occurrence of unobserved extreme events

The paper develops a framework to estimate factors influencing vital rates and infer unobserved extreme events using long-term tag-recapture data from brown trout.
