Swimming abilities of temperate pelagic fish larvae prove that they may control their dispersion in coastal areas [PDF]

open access: yes, 2019
The Sense Acuity and Behavioral (SAAB) Hypothesis proposes that the swimming capabilities and sensorial acuity of temperate fish larvae allows them to find and swim towards coastal nursery areas, which are crucial for their recruitment. To gather further

Parasites Are Paramount: Vertical Trophic Positions of Parasitic Catfishes in a Tropical River Food Web

open access: yesEcology of Freshwater Fish, Volume 34, Issue 4, October 2025.
ABSTRACT The Neotropical catfish family Trichomycteridae contains parasitic fishes that include scale and mucus feeders (subfamily Stegophilinae) and blood feeders (i.e., ‘candirus’, subfamily Vandelliinae). The influence of parasitic catfishes on food web dynamics is unknown.

Environmental DNA Reveals the Fish Community Structure Exhibited Instability and Trend of Miniaturization in the Xijiang River Basin of the Guizhou

open access: yesEcology and Evolution, Volume 15, Issue 9, September 2025.
Monitoring of fish communities is of great significance for the management and sustainability of river ecosystems. Environmental DNA (eDNA) metabarcoding technology has been demonstrated to be a highly sensitive biomonitoring tool. Nevertheless, it has seldom been tested in mountainous rivers within the geographically complex Karst region.
