Research Trends on Trace Element Contamination in Brazilian Urban Lentic Ecosystems: Environmental and Policy Drivers

open access: yesInternational Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Lentic ecosystems are vulnerable to contamination by trace elements, which can accumulate and pose risks to aquatic life and human health. In a large, developing country such as Brazil, marked by vast geographic, environmental, and socioeconomic diversity, it is crucial to understand how these factors shape research on this group of ...

A Systematic Review of Biofloc Technology and Periphyton in Giant Freshwater Prawn (Macrobrachium rosenbergii) Aquaculture

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
Biofloc technology and periphyton‐based systems enhance the sustainable production of giant freshwater prawn (Macrobrachium rosenbergii). A PRISMA‐guided review (2005 – 2024) shows that BFT improves survival (75 – 78 %) and feed efficiency, while periphyton supports natural productivity in grow‐out.

From Infestation to Recovery: Evaluating Changes in Livelihoods and Fishing Productivity Following the Biocontrol of Kariba Weed Along Kyoga Basin Lakes and Kibimba Dam

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT The invasive kariba weed (Salvinia molesta) has severely degraded aquatic ecosystems in Uganda's Kyoga basin lakes and Kibimba Dam, disrupting fisheries, navigation and community livelihoods. Between 2017 and 2021, the National Agricultural Research Organisation implemented a biological control program using the host‐specific weevil ...

Juvenile and Adult Three‐Spined Sticklebacks Exhibit Different Habitat Use in Shallow Baltic Sea Bays

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Three‐spined sticklebacks (Gasterosteus aculeatus) have become dominant in many Baltic Sea coastal fish assemblages, yet life‐stage‐specific habitat use remains poorly understood. We surveyed shallow water habitats along the coast of Gotland, Sweden, to examine how juvenile and adult stickleback abundances relate to variables such as submersed

Abiotic drivers of co‐occurrence and diversity patterns of Calopterygidae species in Amazonian protected freshwaters

open access: yesEcological Entomology, Volume 51, Issue 2, Page 235-249, April 2026.
Species co‐occurrences rely on their ability to explore similar or distinct available resources, and possible niche overlap can prevent their presence and establishment in a given site Damselflies of the Calopterygidae family demonstrated negative co‐occurrences in streams inside and outside PAs, highlighting that their ecological similarity is ...

Brown Trout Abundance in Boreal Streams With Large Wood

open access: yesEcology of Freshwater Fish, Volume 35, Issue 2, April 2026.
ABSTRACT Large wood has been found to be a crucial component in riverine ecosystems. However, due to the heavy channelization of rivers and intensive forestry practices over the past few decades, the amount of large wood in these ecosystems has decreased worldwide. River restoration aims to mitigate the effects of channelization and restore the channel

Marsh Interspersion and Muskrat (Ondatra zibethicus) Habitat Use

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
We used camera traps to measure intensity of habitat use by muskrats along a gradient of marsh interspersion to determine whether reduced interspersion, which may be linked to the invasion of Typha x glauca, may be contributing to widespread muskrat population declines.

Modeling Trophic Structure and Ecosystem Functioning of the Small Fish‐Dominated Largest Lake of Bangladesh

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
Kaptai Lake is a developing ecosystem with a linear food web and thereby vulnerable to external influences. The apex predator, Catfish (TL‐3.364), occupied the top trophic niches, while the overabundant (B: 3.264 t/km2) Clupeid (TL‐2.56) dominated the lower trophic level in the food web. The higher values of ecotrophic efficiency for most of the groups

Environmental DNA Reveals Diverse and Depth‐Stratified Biodiversity in East Indian Ocean Submarine Canyons

open access: yesEnvironmental DNA, Volume 8, Issue 2, March/April 2026.
Environmental DNA metabarcoding reveals diverse animal communities across Cape Range and Cloates submarine canyons off Western Australia. Two assays detected 234 species spanning 125 families across 11 phyla, highlighting canyon‐specific assemblages and demonstrating the value of eDNA for establishing biodiversity baselines in remote and poorly ...

Remobilisation of fine sediment from chalk stream gravel beds under flushing flows: A flume experiment

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
Through progressive flume experiments, this study demonstrated that increased bed shear stresses corresponded with increased cohesive fine sediment (<62‐μm) remobilisation depths from a representative chalk stream gravel bed. This represents some of the first scientifically robust data, which can direct revised and targeted fine sediment management in ...
