Characteristics of benthic macroinvertebrate communities in a typical high sediment-loaded river in China

Journal of Freshwater Ecology
To date, the knowledge of benthic macroinvertebrates in the upper reaches of the Jinsha River remains quite limited compared to other rivers in China due to the difficulty of sampling and special geographical environment.

Ecological Health Assessment of the Vam Co River System, Vietnam: Insights from Benthic Macroinvertebrates and Environmental Changes [PDF]

Nature Environment and Pollution Technology
This study investigated the relationships between benthic macroinvertebrates and environmental variables in the Vam Co River system in southern Vietnam. Field surveys were conducted four times from May to November 2023 to evaluate seasonal variations in ...

Invasive goldfish trigger a regime shift in experimental lake ecosystems of varying trophic state. [PDF]

J Anim Ecol
The pet trade distributes exotic animals around the globe that enrich human lives. However, some pets become pests when released into the wild. This study provides experimental evidence that goldfish will negatively affect native freshwater organisms and ecosystems.

Benthic macroinvertebrates in Italian rice fields

Journal of Limnology, 2013
Rice fields can be considered man-managed temporary wetlands. Five rice fields handled with different management strategies, their adjacent channels, and a spring were analysed by their benthic macroinvertebrate community to i) evaluate the role of rice agroe- cosystem in biodiversity conservation; ii) find indicator species which can be used to ...

Sediment Vulnerability Ranking for River Basins Across the Contiguous U.S. Using Integrated Biophysical and Social‐Ecological Data

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 5, October 2026.
ABSTRACT Nearly half of streams and rivers in the United States (U.S.) have fair to poor conditions for aquatic ecosystem health as declared by the U.S. Environmental Protection Agency, and sediment was identified as a primary factor impairing these waterbodies.

Bioaccumulation of 137Cs by benthic plants and macroinvertebrates

Oceanological and Hydrobiological Studies, 2011
Abstract 137Cs activity concentrations were determined in macrophytes and macrozoobenthic organisms from the southern Baltic Sea. Cesium isotope content was analysed in macroalgae species (green, red and brown algae representatives) and in some species of vascular plants.

Tapeworm Parasite Burden Is Linked to Diet, Body Size, Condition, Growth, Restocking and Habitat Use in Piscivorous Salmonids of a Subarctic Lake

Ecology of Freshwater Fish, Volume 35, Issue 4, October 2026.
ABSTRACT Parasites affect hosts in interaction with the entire ecological community. This is particularly evident for trophically transmitted parasites, such as Dibothriocephalus tapeworms, which infect multiple intermediate fish hosts, potentially reducing their fitness and suitability for human consumption.

Integrating Acoustic Telemetry and Stable Isotope Data Reveals Overlap in Resource Use by Large‐Bodied Fishes in a Temperate Lake

Ecology of Freshwater Fish, Volume 35, Issue 4, October 2026.
ABSTRACT Temperate lake ecosystems undergo seasonal shifts that disproportionately alter the availability of suitable habitat for fishes of different thermal guilds. While many studies have investigated fish habitat use patterns, few have estimated the degree to which fish species overlap in space across seasons from a three‐dimensional perspective ...

Exploring the Geodiversity—Biodiversity Relationships in Freshwaters for Environmental Conservation: A Global Systematic Literature Review

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 9, September 2026.
ABSTRACT Geodiversity refers to the heterogeneity of abiotic characteristics in nature, and in freshwater ecosystems, it mostly mirrors the diversity of hydro‐geomorphological features in inland waters. Although several scholars have highlighted that geodiversity contributes to habitat formation and influences biodiversity and ecological processes, it ...

Contrasting Temporal Dynamics of Ostracod (Crustacea) Communities in Protected and Impacted Areas in a Brazilian Floodplain

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 9, September 2026.
ABSTRACT Environmental integrity is vital for the long‐term preservation of freshwater biodiversity, which is currently among the most threatened on Earth due to anthropogenic pressures such as dam construction. The present study investigated the temporal responses of ostracod communities over 8 years (2017–2024) in the Upper Paraná River floodplain ...
