Metabarcoding Unveils the Diversity and Dynamics of In Situ Diet and Symbionts Associated With Copepods in Chinese Coastal Waters

open access: yesDiversity and Distributions, Volume 31, Issue 6, June 2025.
ABSTRACT Aim Copepods are the key secondary producers in marine ecosystems, yet their in situ diet and symbionts remain underexplored due to technical challenges, limiting our understanding of their population dynamics and ecological functions. Using DNA metabarcoding, we jointly characterised the natural diet and symbionts of copepods across Chinese ...

Selective Retention of Long‐Chain Polyunsaturated Fatty Acids in Heptageniidae (Ephemeroptera) of Subalpine Streams

open access: yesFreshwater Biology, Volume 70, Issue 6, June 2025.
ABSTRACT Benthic macroinvertebrates are crucial for linking dietary energy from the base of aquatic food webs to consumers at higher trophic levels. Ephemeroptera (mayfly) grazers rely on periphyton as their primary source of essential dietary nutrients, such as polyunsaturated fatty acids (PUFA) and other lipids.
