Diversity and Spatiotemporal Distribution of Fish in a Highland Lake in China Based on Environmental DNA Metabarcoding

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
We analyzed water samples from different seasons and locations in Erhai Lake to determine whether eDNA barcoding can effectively show the diversity of fish in such lakes. In the manuscript, we discuss our findings regarding the range of species found, their spatiotemporal distribution, and whether eDNA barcoding gave similar results to traditional ...

Sulawesi Stream Fish Communities Disconnected From the Sea: Absence of Diadromous and Dominance of Exotic Species

open access: yesFreshwater Biology, Volume 70, Issue 12, December 2025.
ABSTRACT Barriers can profoundly alter the composition of stream communities. In the tropical island of Sulawesi, streams are inhabited by a diversity of secondary freshwater fishes, mostly diadromous species. Many streams, however, are modified by human activities for various reasons, involving the construction of barriers that impede fish migration ...
