An experimental approach to assess the combined effects of multiple stressors on a large vertebrate species

open access: yesConservation Biology, EarlyView.
Abstract The design of experiments to investigate the combined effects of multiple stressors requires exposing target organisms to multiple combinations of stressor doses. Concurrent manipulation of stressors is often infeasible with wildlife, but long‐lasting health effects allow individual health to be used as an integrator of prior stressor exposure.

Abstract The Narrative Policy Framework lacks clear and empirical explanations of power. Yet, the study of narratives is inherently the study of power in shaping policy outputs and decisions. We develop a conceptual model positing that expressions of power (power to, with, and over) may be discovered in narrative constructs (e.g., narrative structure ...
