Consumption of periphyton and bioseston by Mozambique tilapia in aqua dams with three different substrates

Aquaculture Environment Interactions
Periphyton-based aquaculture can reduce feed input costs. Here we characterised the periphyton and bioseston formation in aqua dams stocked with net, plastic, and stone substrates.

Periphyton effects on bacterial assemblages and harmful cyanobacterial blooms in a eutrophic freshwater lake: a mesocosm study

Scientific Reports, 2017
Periphyton comprises a broad range of autotrophic and heterotrophic organisms that grow on submerged surfaces in aquatic environments. To investigate the ecological roles of periphyton and their symbiotic bacterial assemblages related to the control of ...

Periphyton and Benthic Macroinvertebrate Response to Antimycin Piscicide During Brook Trout Restoration

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT The piscicide antimycin has been used as an effective fish toxicant to eradicate nuisance fishes because it is not as detectable by fish as other chemical piscicides. We evaluated the effects of antimycin and its detoxicant, potassium permanganate, on periphyton and benthic macroinvertebrates during a brook trout (Salvelinus fontinalis ...

Periphyton pigment shifts in lakes with varying water colour: a possible monitoring method for freshwater Browning

Ecological Indicators
Despite several negative effects of browning, there are no sufficient bioindicators to monitor it. In this study, the effects of water quality on the photosynthetic pigment content of periphyton grown on artificial substrata in different depths were ...

Phenotypic Plasticity Across Gradients of Predation and Competition in Larval Amphibians

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Many taxa encounter a wide range of conditions for any particular environmental variable and they experience variation in multiple environmental variables simultaneously, which may have interactive effects if different environmental types induce opposing phenotypes.

The effects of seasonality and parasitism on diet and habitat selection in the common periwinkle

Oikos, Volume 2026, Issue 4, April 2026.
The common periwinkle Littorina littorea is an ecologically important grazer, known for its strong influence on algal communities and its role in structuring ecosystems. It serves as the first intermediate host for several trematode species in the Baltic Sea, especially for the fluke Cryptocotyle lingua.

Identifying knowledge gaps about context dependency in freshwater species invasions

Oikos, Volume 2026, Issue 4, April 2026.
The abiotic template of freshwater ecosystems is being altered by human activity on a global scale, often promoting the establishment of new invasive taxa and increasing the likelihood of facilitation between invaders. These positive interactions represent a substantive threat to freshwater ecosystems by promoting the establishment and persistence of ...

Trophic Diversity in Aquatic Food Webs Along a Tropical Coastal River Continuum in West‐Central Africa

Freshwater Biology, Volume 71, Issue 4, April 2026.
ABSTRACT In the wet Afrotropics, information on trophic diversity and resource use in freshwaters is extremely limited. Here we used stable isotope ratios (δ13C, δ15N) from food webs along the continuum of a coastal river in the Republic of the Congo to examine seasonal and spatial patterns of trophic diversity.

Dry and Exposed: Effects of Riparian Vegetation on Abiotic and Biotic Characteristics of Intermittent Streams

Freshwater Biology, Volume 71, Issue 4, April 2026.
ABSTRACT Many perennial streams in Central Europe have become intermittent due to climate change and human pressures. The loss of surface water has a dramatic impact on freshwater biota. Species inhabiting intermittent streams must exhibit particular life‐history strategies to survive dry periods.

Sediment phosphorus release sustains nuisance periphyton growth when nitrogen is not limiting

Journal of Limnology, 2020
Nuisance periphyton growth influences the aesthetics, recreation, and aquatic life of waterbodies. Partners Lake is a shallow spring-fed lake in the headwaters of the Illinois River Watershed in Cave Springs, Arkansas, that experiences nuisance growth of
