Trophic Redundancy and the Hidden Dietary Overlap Between Native and Invasive Stream Fishes

Ecology of Freshwater Fish, Volume 35, Issue 3, July 2026.
ABSTRACT Biological invasions introduce non‐native species into natural ecosystems, often reshaping localcommunities and altering trophic interactions. In freshwater environments, such invasions can intensify resource use and threaten native fish diversity.

Dispersal of invasive species by drifting

Current Zoology, 2011
Drifting can be an effective way for aquatic organisms to disperse and colonise new areas. Increasing connectivity between European large rivers facilitates invasion by drifting aquatic macroinvertebrates.

Macroinvertebrates on the front lines: projected community response to temperature and precipitation changes in Mediterranean streams

Journal of Freshwater Ecology, 2017
As temperatures rise and precipitation patterns change, approaches are needed for early detection of the effects on ecosystems. Macroinvertebrate data collected from 81 sites with multiple habitat kick sampling were compiled for this study.

Low‐Head Dam Removal Restores Biofilm Structure but Not Function in a Temperate Stream

International Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Barrier removal is a common stream restoration practice aimed at restoring longitudinal connectivity, yet its effects on biofilm structure and function, through alteration of near‐bed hydrodynamics, remain unclear. Using a space‐for‐time substitution approach, we assessed how the presence and removal of a low‐head dam affect biofilm structure ...

Topic Modeling of Fatty Acid Studies: Evaluating Environmental Changes in Freshwater Ecosystems

International Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Fatty acids (FAs) are biochemical molecules with vital structural and metabolic functions in all living organisms. Over the last decades, FA analysis in ecological studies has garnered significant attention due to its diverse applicability, such as taxonomic support for species identification, investigations on trophic interactions, and ...

Riparian Restoration Improves Physical Habitat but Not Ecosystem Functioning to Reference Levels in Urban Neotropical Streams

International Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Urbanization modifies stream ecosystems through changes in land use and water quality, with particularly understudied effects in tropical regions. This study evaluates how the conservation status (reference, restored, and impacted) influences nutrient enrichment and organic matter decomposition—key indicators of ecosystem function—across five ...

Pre-impoundment Limnological Study of the Strawberry River in Northeastern Arkansas [PDF]

, 1971
A study of pre-impoundment limnological characteristics of the Strawberry River was made from August, 1967 to June, 1968. Two collecting stations were established, one upstream which would not be inundated and a lower station which would be inundated ...
