Application of environmental DNA metabarcoding to identify fish community characteristics in subtropical river systems. [PDF]

Ecol Evol
Environmental DNA (eDNA), coupled with PCR and next‐generation sequencing, and electrofishing were used to compare their effects in identifying fish community characteristics. Our results demonstrated that eDNA metabarcoding can be used as an effective tool in revealing fish composition and diversity, which is important for using the eDNA technique in ...

Spatial Variation in Food Web Structures, Energy Flows, and System Attributes Along the Pearl River and Their Indications of Protection and Restoration. [PDF]

Ecol Evol
The undisturbed island zone, which provided essential feeding/spawning habitats, should be protected to maintain river health. The food web structure in the industrial zone was collapsed due to water pollution and habitat degradation. The appearance of softshell turtles and herbivorous/molluscivorous fish can be used to indicate the integrity of the ...
