Structural characteristics and environmental impact factors of submerged macrophytes communities during the natural restoration period of urban lakes with different trophic levels

Scientific Reports
Research on the dynamics and driving mechanisms of submerged macrophytes communities during the natural restoration period of lakes with different trophic level remains relatively scarce.

Combined Effects of Algae‐Supplemented Feeding Regimes and Water Temperature on Sperm Quality of Common Carp (Cyprinus carpio) Broodstock During Spawning

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT This exploratory study investigated associations between dietary algae supplementation (1% and 3%) and sperm quality in male common carp (Cyprinus carpio) broodstock during two consecutive spawning seasons under commercial farming conditions. Sperm quality was evaluated using conventional motility and kinetic parameters together with analyses ...

Herbivory on freshwater macrophytes

Aquatic Botany, 1991
Abstract Conventional wisdom holds that live macrophytes are rarely consumed and are functionally unimportant in aquatic food webs. With a review of the literature, I first demonstrate that macrophyte biomass, productivity, and species composition is often influenced by a variety of vertebrate and invertebrate grazers.

Influence of inlet water on the biotic and abiotic variables in a fish pond

Brazilian Journal of Biology
The effects of treated and untreated water inlets with macrophytes on the improvement of water quality and zooplankton community were evaluated in a fish pond with continuous water flow.

Use of Invasive Rugulopteryx okamurae Beach Wrack as Habitat and Food by Talitrus saltator

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 8, August 2026.
ABSTRACT The introduction of non‐native algae into coastal waters has increased worldwide, causing a range of ecological and socio‐economic impacts. However, when stranded on beaches as wrack, these invasive algae can provide refuge and food for supralittoral organisms, potentially benefiting local fauna communities and beach functioning. In this study,

Optimising the Detection of Southern Toadlets (Pseudophryne semimarmorata): A Comparative Study of eDNA and Conventional Survey Methods

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 8, August 2026.
ABSTRACT Accurate and reliable monitoring of amphibians is essential for informing their conservation. Pseudophryne semimarmorata (southern toadlet) is a species of endangered brood frog with a largely terrestrial life history that has experienced widespread decline across southern Australia.

Temporal Shifts in Subtidal Rocky Benthic Communities Associated With the Invasion of Rugulopteryx okamurae in a Port Environment

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 8, August 2026.
ABSTRACT The invasive brown alga Rugulopteryx okamurae, native to the northwestern Pacific, has rapidly expanded along the European Atlantic coast, reaching the Basque Coast in 2023, and was likely already present in 2022. Using annual data from a monitoring survey conducted between 2010 and 2025, this study assesses the spatio‐temporal variability of ...

Energy Channel Coupling by Mid‐Trophic Level Fish Challenges the Landscape Theory for Food Web Architecture in a Large Tropical Lake Ecosystem

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Lake Turkana, a large tropical East African Great Lake, is an ideal model for examining how consumer fish species may mediate the coupling of fast and slow energy channels within food webs. We explored the ecological niche dynamics of five important Lake Turkana fish species across ontogeny and used a Bayesian isotope mixing model approach to identify ...

Effects of Simulated Herbivory on the Thermal Resilience of Two Temperate Seagrass Species

Ecology and Evolution, Volume 16, Issue 8, August 2026.
This study investigates how reduced leaf size via simulated herbivory influences the thermal performance of temperate seagrasses. Simulated herbivory enhanced physiological performance and resilience under elevated temperatures in Posidonia australis, but not in Heterozostera tasmanica.
