Post‐Release Survival and Behavioral Recovery of a Rehabilitated Short‐Finned Pilot Whale (Globicephala macrorhynchus) in the South China Sea Revealed Through Satellite Tracking

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
This study presents the first empirical evidence of successful rehabilitation and post‐release monitoring of a short‐finned pilot whale in the South China Sea—a region where such data are critically lacking despite frequent stranding events. Using satellite telemetry and a dedicated resighting expedition, we documented the 52‐day movement, diving ...

Major contribution of particle‐associated microbes to deep‐sea organic carbon degradation

open access: yesLimnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract The biological carbon pump mediates the export of particulate organic carbon from the euphotic zone to the deep ocean, where it provides the base of the food web. Although deep‐sea microbial metabolism is considered to be largely associated with macroscopic particles, such as marine snow, the specific contribution of particle‐associated ...
