Continental scale metagenomics reveals Microcystis‐induced synchrony among aquatic taxa is exacerbated by trophic cascades

open access: yesEcography, EarlyView.
Harmful Microcystis proliferation severely threatens aquatic ecosystems globally, but its impacts on food‐web stability remain poorly understood. Here, we analyzed 1309 metagenomic samples from freshwater ecosystems across China to investigate how Microcystis abundance affects synchrony among taxa in multi‐trophic food webs (from bacteriophages to ...

Half a Century of Per‐ and Polyfluoroalkyl Substances in Northern Gannet Eggs: Impact of Regulations

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Per‐ and polyfluoroalkyl substances (PFAS), known as “forever chemicals”, are persistent organic pollutants that have been widely used in the industry across the globe for many decades. Their chemical stability, bioaccumulation, and toxicity pose major environmental and health risks. This study examines temporal trends in the concentrations of

Field evaluation of artificial intelligence early warning for bird depredation at carp ponds

open access: yesWildlife Society Bulletin, EarlyView.
An artificial intelligence‐based early‐warning workflow for bird depredation at a commercial carp farm in Japan. Abstract Piscivorous birds such as the great cormorant (Phalacrocorax carbo) can cause substantial losses in pond aquaculture, yet continuous on‐site vigilance is difficult under labor shortages.
