Simulating drifting fish aggregating device trajectories to identify potential interactions with endangered sea turtles

open access: yesConservation Biology, Volume 38, Issue 6, December 2024.
Abstract Purse‐seine fishers using drifting fish aggregating devices (dFADs), mainly built with bamboo, plastic buoys, and plastic netting, to aggregate and catch tropical tuna, deploy 46,000–65,000 dFADs per year in the Pacific Ocean. Some of the major concerns associated with this widespread fishing device are potential entanglement of sea turtles ...

Evil and allies: Opportunistic gulls as both spreaders and sentinels of antibiotic‐resistant bacteria in human‐transformed landscapes

open access: yesJournal of Applied Ecology, Volume 61, Issue 11, Page 2809-2821, November 2024.
The integration of GPS data, pathogen testing and network analyses can shed further light on pathogen dynamics by creating spatial risk maps and identifying ARB sources. In combination with complementary molecular epidemiology techniques within a One Health framework, our approach can emerge as an important tool for monitoring ARB dynamics within ...

Key role for nuclear energy in global biodiversity conservation

open access: yesConservation Biology, Volume 29, Issue 3, Page 702-712, June 2015., 2015
Abstract Modern society uses massive amounts of energy. Usage rises as population and affluence increase, and energy production and use often have an impact on biodiversity or natural areas. To avoid a business‐as‐usual dependence on coal, oil, and gas over the coming decades, society must map out a future energy mix that incorporates alternative ...
