Validating antler‐ and movement‐based estimates of caribou reproduction using video camera collars Validation des estimations de la reproduction du caribou basées sur la rétention des bois et  sur le déplacement à l'aide de colliers‐caméras

open access: yesThe Journal of Wildlife Management, EarlyView.
We used GPS video camera collar data from barren‐ground caribou in the Porcupine and Western Arctic herds to validate antler‐ and movement‐based methods for estimating annual reproductive metrics. Antler retention was highly accurate for estimating parturition, but the movement methods we tested performed marginally for estimating parturition and ...

An Adaptive Multiple Shooting Strategy for Optimal Control

open access: yesOptimal Control Applications and Methods, EarlyView.
We study how multiple shooting affects the convergence of Newton‐type methods for optimal control, comparing several shooting strategies across 40 benchmark problems. The study covers interior‐point and sequential quadratic programming methods with both Quasi‐Newton approximations and exact Hessians.

More than proteins for empty stomachs: Wild meat in the BaTonga food system

open access: yesPeople and Nature, EarlyView.
Abstract Our paper highlights the limitations of the framework used by many conservation‐focused programmes that incorporate food security objectives. This framework encourages the substitution of wild proteins with domestic proteins by promoting animal farming in communities located near conservation areas.
