Contrasting impacts of invasive engineers on freshwater ecosystems: an experiment and meta-analysis
TLDR
Both carp and crayfish have profound effects on community composition and ecosystem processes through combined consequences of bioturbation, excretion, consumption and non-consumptive destruction, indicating that they have differential ecosystem impacts. Expand
Effects of common carp on nutrient dynamics and littoral community composition: roles of excretion and bioturbation
TLDR
Carp can have dramatic direct and indirect impacts on nutrient dynamics and littoral community structure through excretion and bioturbation, indicating that ecosystem engineering by carp may trigger a shift from a clear water state dominated by submerged macrophytes to a turbid water statedominated by phytoplankton. Expand
Behavioural and morphological differences between feral and domesticated strains of common carp Cyprinus carpio.
TLDR
The present results appear to indicate the possibility that domesticated C. carpio could re-adapt to the wild environment during a short evolutionary period, although further research using more feral strains is required. Expand
A laboratory study of the effects of shelter availability and invasive crayfish on the growth of native stream fish
TLDR
It is demonstrated that reduced shelter availability and ⁄ or crayfish invasion can have significant, indirect negative effects on the growth performance of native fish, but whether those effects are interactive might vary depending on the species. Expand
Potential impacts of non-native channel catfish on commercially important species in a Japanese lake, as inferred from long-term monitoring data
TLDR
The potential impacts of invasive channel catfish, which have multiplied dramatically since around 2000 in Lake Kasumigaura, Japan, on native fish and shrimp and the commercial fishery using fishery-independent, quantitative long-term monitoring data (1993–2007), are assessed. Expand
Bottom-up linkages between primary production, zooplankton, and fish in a shallow, hypereutrophic lake.
TLDR
Top-up linkages between nutrient, primary production, and zooplankton abundance might be a key mechanism supporting high planktivore abundance in eutrophic lakes, and this study highlights the need for ecosystem management to resolve the conflict between good water quality and high fishery production.

Asymmetric dispersal structures a riverine metapopulation of the freshwater pearl mussel Margaritifera laevis
TLDR
This work hypothesized that water-mediated dispersal would overwhelm upstream dispersal via host fish, and therefore, that upstream subpopulations play a critical role as immigrant sources, and examined the effects of both up- and downstream immigrant sources on the size of target subpopulation in the Shubuto River system, Hokkaido, Japan. Expand
Functional diversity promotes phytoplankton resource use efficiency
TLDR
This study provides empirical evidences in natural aquatic systems that trait-based functional diversity represents better species niche partitioning than the Shannon index and thereafter enhances resource use efficiency. Expand
Trends and stability of inland fishery resources in Japanese lakes: introduction of exotic piscivores as a driver.
TLDR
It is suggested that increasing exotic piscivore species may diminish the resources and their stability, particularly in Japanese lakes where native piscvores are rare, and this might lead to a substantial decline in ecosystem services. Expand
