Impact of Anthropogenic Activities and Climate Change on the Wetlands in the North‐West of Madagascar

Plant-Environment Interactions, Volume 7, Issue 5, October 2026.
ABSTRACT Macrophytes are vulnerable to various factors in their natural ecosystems, including climatic, ecological, and anthropogenic changes. This study aims to document how these factors influence floristic composition. Four sites were investigated in the Boeny Region of northwest Madagascar: Ambatoboeny, Marovoay, Ankarafantsika National Park, and ...

A Multi‐Method Approach to Assessing Barrier Effectiveness in Preventing the Spread of Invasive Signal Crayfish (Pacifastacus leniusculus)

River Research and Applications, Volume 42, Issue 8, Page 1691-1704, October 2026.
ABSTRACT Relieving barriers and increasing free flowing rivers is a global imperative to restore habitat connectivity for migratory fish stocks. While reducing river fragmentation will certainly improve biodiversity, the spread of non‐native species throughout a river system may be facilitated as an inadvertent outcome.

Environmental pollution and sustainable restoration of the Yamuna River: A review of water quality, health risks, and phycoremediation

River, Volume 5, Issue 3, Page 398-418, August 2026.
Abstract The Yamuna River, one of India's most significant river systems and the largest tributary of the Ganges River, serves critical ecological, socio‐economic, and cultural functions. However, rapid urbanization, industrialization, and intensive agriculture have severely degraded its water quality, resulting in extensive pollution with untreated ...

Simulating Carbon Emission Dynamics in Agricultural Drainage Ditches: Development and Evaluation of the PCDitch‐Carbon Model

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 10, October 2026.
Abstract With their high abundance in agricultural landscapes, drainage ditches are important components of the global water cycle and potential carbon (CO2 and CH4) emission hotspots. However, explicit process‐based estimates of carbon emissions from these systems are lacking, with ditch biogeochemical complexity being a major constraining factor.

Influence of environmental variables on macroinvertebrates in a macrophyte-dominated Chinese lake, with emphasis on the relationships between macrophyte heterogeneity and macroinvertebrate patterns

, 2005
The benthic community structure in Baoan Lake was examined in relation to lake water physicochemical characteristics and biological parameters. Seventy macroinvertebrate taxa were identified, and mollusks constituted the dominant group and accounted for ...

Methane Uptake by Inland Waters: Fact or Fiction?

Global Biogeochemical Cycles, Volume 40, Issue 10, October 2026.
Abstract Inland waters are widely known as net emitters of methane (CH4) to the atmosphere, contributing ∼15% of global CH4 emissions. CH4 is produced by anaerobic methanogens in aquatic sediments, but net CH4 emissions at the water–air interface are modulated by CH4 oxidation by methanotrophs in the water column.

Ecological Processes in Macrophyte- and Phytoplankton-Dominated Shallow Lakes

, 2006
Stratified lakes often receive more attention from limnologists although most of the worlds lakes are indeed shallow. This study describes ecological processes in three shallow lakes, one dominated by macrophytes, one by phytoplankton, and one with both ...

Effects of Reduced Precipitation and Water Level Variability on Phytoplankton Dynamics and Thermal Structure in a Large Tropical Reservoir

Water Resources Research, Volume 62, Issue 10, October 2026.
Abstract Drought is one of the most severe and complex natural hazards causing changes in water balance and impeding crucial water‐dependent ecosystem services. Over the last 25 years, multiple severe droughts linked to El Niño events have affected the Zambian and Zimbabwean regions.

Changes in the taxonomic structure of periphytic algae on a free-floating macrophyte (Utricularia foliosa L.) in relation to macrophyte richness over seasons

, 2018
Periphyton has a strong relationship with aquatic macrophytes, which are key components of spatial heterogeneity in the littoral zone. We evaluated the relationship between the community structure of periphytic algae on Utricularia foliosa and macrophyte

Seasonal Baseline Evaluation of Physicochemical Parameters and Culturable Bacterial Characteristics in Northwestern Himalayan Ramsar Sites

Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.
Seasonal monitoring of two Himalayan Ramsar wetlands revealed significant fluctuations in physicochemical parameters and low bacterial diversity across seasons. Elevated dissolved oxygen at Renuka Ji, turbidity and dissolved oxygen at Asan Conservation Reserve levels highlight ecological sensitivity and the need for continuous monitoring and ...
