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

Conservation Biology, Volume 40, Issue 4, August 2026.
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.

Fluid Flow Simulation for Predicting Bottomhole Pressure That Considers Wellbore Storage Effects Under Shut-In Conditions in Deepwater Drilling

Journal of Marine Science and Engineering
Under shut-in conditions in deepwater drilling, the gas invading the bottomhole ascends along the wellbore and accumulates at the wellhead, forming a high-pressure trap, challenging wellbore pressure prediction and control.

Prioritizing Shark, Ray, and Chimaera Conservation in Rapidly Changing Polar Waters

Global Change Biology, Volume 32, Issue 8, August 2026.
Polar sharks, rays, and chimaeras face growing pressures from changing sea‐ice conditions, expanding fisheries, and limited protection. Our assessment highlights where critical habitats occur and how Important Shark and Ray Areas (ISRAs) can support more targeted conservation and fisheries management across the Arctic and Antarctic.

Information Design in Common Value Auction With Moral Hazard: Application to OCS Leasing Auctions

Econometrica, Volume 94, Issue 4, Page 1171-1208, July 2026.
This paper explores the impact of information design on the auctioneer's revenue in the U.S. offshore oil/gas lease auctions where, post‐auction, the winner decides whether to explore the auctioned tract and must pay the government a royalty on its production value.
