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.

Comparative review of entanglement risk assessments for cetacean conservation and management

open access: yesConservation Biology, EarlyView.
Abstract Cetacean entanglement in fishing gear remains a major global threat that exposes persistent gaps in how fisheries management frameworks manage risk to nontarget species. Ecological risk assessment (ERA) offers a structured way to link exposure and consequences to an explicit statement of risk, but entanglement risk assessments vary widely in ...

The distribution of a rarely encountered stingray, Megatrygon microps, informed by citizen science: A systematic review

open access: yesConservation Science and Practice, EarlyView.
This study combines literature and online data sources to expand the smalleye stingray's range, highlight ecological interactions and specific threats. Abstract Many chondrichthyan fishes are experiencing alarming population declines primarily due to overfishing, exacerbated by their inherently vulnerable life history traits including slow growth rates

The catch of the day: The shortcomings of promoting sustainable seafood consumption in Peru

open access: yesConservation Science and Practice, EarlyView.
This study investigates the meaning and application of “catch of the day” in Peru by analyzing 233 news articles and genetically testing 43 fish samples from restaurants. Results show that media frequently use the term as a vague marketing phrase, while genetic testing reveals a 60% mislabeling rate. These findings suggest that “catch of the day” lacks

Deep Dark Futures: Foresighting Human Impacts on Mesopelagic Ecosystem Services

open access: yesFish and Fisheries, EarlyView.
This study uses foresighting to explore four plausible future scenarios of human activity affecting mesopelagic ecosystem services; provisioning, regulating, supporting and cultural. Using participatory scenario development, qualitative network modelling and indicator design, we assess systemic risks and early warning signals linked to harvest, climate
