Benefits of Aquatic Vegetation for Fish in an Ecosystem Dominated by an Invasive Piscivore

Freshwater Biology, Volume 70, Issue 5, May 2025.
ABSTRACT Aquatic vegetation plays vital roles throughout aquatic ecosystems through increasing habitat complexity, providing forage and refuge for a variety of organisms, and also through improving water quality. For fish, a host of studies have found a strong correlation between aquatic vegetation abundance, fish density, and species richness, and ...

Overwintering Fish Community in Ice‐Covered Environments in Hokkaido, Japan, Inferred From Environmental DNA

Environmental DNA, Volume 7, Issue 2, March/April 2025.
Using fish eDNA metabarcoding, we successfully described an overwintering fish community in ice‐covered environments. eDNA data indicated that the dominant species were Clupea pallasii in the lagoon and Tribolodon spp. in the inlet river. Our findings suggested that the eDNA technique is useful for studying ice‐covered areas and could provide new ...

Differences in factors determining taxon‐based and trait‐based community structures: a field test using zooplankton

Limnology and Oceanography, Volume 70, Issue 1, Page 113-127, January 2025.
Abstract Ecological community structure, which has traditionally been described in terms of taxonomic units, is driven by dispersal and environmental filters. Traits have recently been recognized as alternative units for quantifying community parameters, but they may have important differences with taxonomic units. For example, as taxon‐based community

A sedimentary DNA perspective about the influence of environmental and food‐web changes on the microbial eukaryotic community of Lake Biwa

Freshwater Biology, Volume 69, Issue 11, Page 1553-1567, November 2024.
Abstract The impacts of environmental change on Lake Biwa have been explored for decades, with water monitoring and palaeolimnological studies revealing how environmental forcing, including climate warming, eutrophication, water level manipulation and human manipulation of fish populations, has influenced the food web of Lake Biwa.

Pesticides in the Great Barrier Reef catchment area: Plausible risks to fish populations

Integrated Environmental Assessment and Management, Volume 20, Issue 5, Page 1256-1279, September 2024.
Abstract Waterways that drain the Great Barrier Reef catchment area (GBRCA) transport pollutants to marine habitats, provide a critical corridor between freshwater and marine habitats for migratory fish species, and are of high socioecological value.

Vertical eDNA distribution of cold‐water fishes in response to environmental variables in stratified lake

Ecology and Evolution, Volume 14, Issue 3, March 2024.
Vertical eDNA distribution of lake fishes. Abstract In summer, the survival zones of cold‐water species are predicted to narrow by both increasing water temperatures from the surface and by expanding hypoxic zones from the lake bottom. To examine how the abundance of cold‐water fishes changes along environmental gradients, we assessed the vertical ...

Studies on trophic niches of Macrobrachium nipponensis and Exopalaemon modestus

, 2013
This study was undertaken to assess the trophic niches and niche widths between two freshwater shrimps, Macrobrachium nipponensis and Exopalaemon modestus, from the Yangtze River-connected lakes-Dongting lake and Poyang lake-using stable carbon and ...

CRISPR‐based environmental DNA detection for a rare endangered estuarine species

Environmental DNA, Volume 6, Issue 1, January–February 2024.
We present a CRISPR‐based eDNA approach that achieves the high level of sensitivity needed for detection of rare species at low abundance. We tested the method in both controlled (tank experiment) and natural (field sampling) contexts. Our field sample results suggest that CRISPR‐eDNA could be more sensitive than traditional monitoring, by comparison ...
