Revealing the Discrepancy Between Ecosystem Service Flows and Public Perception in Heavily Impacted Lowland Rivers of Armenia

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 9, September 2026.
ABSTRACT River ecosystems are increasingly vulnerable to intensified human pressures associated with population growth and rising living standards, leading to structural changes and altered ecosystem service (ES) provision. The lower course of the Hrazdan River (Armenia) exemplifies these impacts, as it flows through Yerevan, the capital city, and ...

What Drives Seasonal Mat Dynamics in Eutrophic Lake: Allelopathy or Environmental Gradients?

Ecology and Evolution, Volume 16, Issue 9, September 2026.
A two‐season field study of eutrophic Lake Oporzyńskie showed that phenolic compounds and water physicochemistry jointly, but unevenly, drive the mat dynamics of Cladophora glomerata and Lemna minor, with phenolics explaining a much larger part of the variability in mat size than physicochemical parameters.

Estimates of Critical Upper Maxima (CTmax) of Kelp Species Are Strongly Influenced by Biogeography and Thermal History

Ecology and Evolution, Volume 16, Issue 9, September 2026.
Experimentally derived critical thermal maxima (CTmax) are widely used to estimate species' thermal tolerance and increasingly to predict vulnerability to chronic warming. However, evidence shows how CTmax is dynamic and can be strongly influenced by multiple environmental and methodological factors, potentially limiting its application as a fixed ...

The Multiple Roles of Genetics on Freshwater Macrophyte Functional Traits in the Interplay With the Environment: A Review

Ecology and Evolution, Volume 16, Issue 9, September 2026.
This review examines how genetic and environmental factors jointly shape functional trait variation in aquatic plants. By synthesizing the literature from the last fifteen years, we analyze the roles of genetic diversity, epigenetic variation, genome size, and gene expression in relation to phenotypic plasticity, natural selection, and genetic drift ...

Host‐Associated Differentiation of Gut Microbiota Among Four Crane Species Wintering in Rice Paddies Around Poyang Lake

Ecology and Evolution, Volume 16, Issue 9, September 2026.
In this study, we used 16S rRNA gene amplicon sequencing to characterize the fecal microbiota of four crane species wintering in agricultural rice paddies at Poyang Lake, China: Siberian crane (Leucogeranus leucogeranus), hooded crane (Grus monacha), white‐naped crane (Grus vipio), and common crane (Grus grus).

Unveiling Zooplankton Diversity Patterns: The Differential Influence of Macrophyte Belts on Species and Functional Metrics

Diversity
Species and functional diversity are essential frameworks for analyzing changes in planktonic communities. In lakes and rivers, macrophytes within the coastal zone are a primary determinant of zooplankton community structure and function.

Comprehensive effects of lake dredging on microbial community and dissolved organic matter compositions in surface sediments

Ecological Indicators
Sediment dredging and submerged macrophyte restoration are effective ways to improve water quality, especially in eutrophic shallow lakes. However, the impact of dredging on the interactions between dissolved organic matter (DOM) and microbial ...

Spatial and temporal dynamics of functional groups of phytoplankton in a tropical shallow lake

Acta Limnologica Brasiliensia, 2018
Aim To evaluate the structure and dynamics of functional phytoplankton groups (FGs) over a macrophyte cover gradient and their relations with environmental variable in small, shallow clear-water lake.

Monitoring the Extraordinary Ephemeral Emergence of Myriophyllum spicatum L. in the Coastal Lagoon Albufera of Valencia (Spain) and Assessing the Impact of Environmental Variables Using a Remote Sensing Approach

Journal of Marine Science and Engineering
The Albufera of Valencia, a Mediterranean coastal lagoon, has been in a turbid state since 1974, with only four episodes of temporary water transparency in spring. Despite its average depth of 1 m and oligohaline waters, excessive turbidity, fish grazing,
