Influence of glyphosate and its metabolite aminomethylphosphonic acid on aquatic plants in different ecological niches

Ecotoxicology and Environmental Safety, 2022
Glyphosate and its metabolite aminomethylphosphonic acid (AMPA) draw great concern due to their potential threat to aquatic ecosystems. The individual and combined effects of glyphosate and AMPA on aquatic plants in different ecological niches need to be

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

Aquaculture, 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

Brown Trout Abundance in Boreal Streams With Large Wood

Ecology 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

The effects of nutrient level on periphyton–macrophyte interactions in freshwater ecosystems

Water Biology and Security
Periphyton are one of the key primary producers in aquatic ecosystems, particularly in oligotrophic shallow lakes. Submerged macrophytes are capable of competing with periphyton for nutrients and light, but may also facilitate periphyton by providing ...

Influence of submerged macrophytes on phosphorus in a eutrophic reservoir in a semiarid region

Journal of Limnology, 2020
Phosphorus (P) is the main nutrient responsible for the harmful effects caused by the enrichment of aquatic systems, and submerged macrophytes play an important role in this process, since they can both remove and release this nutrient in environmental ...

Vertical optical complexity shaped by submerged macrophytes

Scientific Reports
AbstractThe influence of macrophytes on the optical environment of the littoral zone was assessed by studying the effect of monospecific Potamogeton perfoliatus on the quantitative and qualitative properties of light and the response of plants to this altered environment. P.

Consumer resilience suppresses the recovery of overgrazed ecosystems

Ecological Applications, Volume 36, Issue 2, March 2026.
Abstract Many heterotroph species perish when faced with severe food limitation; others can persist, adapt, and thrive. Sea urchins are emblematic of this paradox: they can overgraze kelp forests to form barren habitats, but can then survive for decades in these nutritionally depauperate seascapes.

Simple relationships to predict attributes of fish assemblages in patches of submerged macrophytes

Neotropical Ichthyology
Submerged macrophytes play an important role in structuring habitats and, therefore, in determining patterns of aquatic biodiversity. Because these plants are widespread in shallow areas of many Neotropical reservoirs, the present work investigated if ...

Marsh Interspersion and Muskrat (Ondatra zibethicus) Habitat Use

Ecology 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.

Leachates and elemental ratios of macrophytes and benthic algae of an Andean high altitude wetland

Journal of Limnology, 2011
In wetlands, macrophytes and filamentous algae constitute an important carbon source for the total content of Dissolved Organic Matter (DOM) of the environment.
