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 ...

Aquatic macrophytes of Angola: a preliminary verified checklist

PhytoKeys
Aquatic macrophytes are photosynthetic macroscopic organisms that grow permanently or periodically submerged or floating on the surface of the water. The aim of this study is to compile a checklist of fresh-water aquatic vascular plant macrophytes occurring in Angola, focusing on their origins, life forms, conservation status and distribution ...

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.

The Influence of Macrophytes on Aquatic Microclimate

, 2023
How terrestrial vegetation influences microclimate and what effects this has on associated ecosystems is well studied, but it is less known if and how aquatic macrophytes affect their microclimate. In this study I therefore aim to investigate the question of how aquatic macrophytes influence their microclimate, and how these effects in turn may affect ...

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 ...

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.

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 ...

Leveraging Species Associations Patterns of Macroalgae in Wrack to Predict Their Spatial Distribution

Diversity and Distributions, Volume 32, Issue 10, October 2026.
ABSTRACT Aim Species associations are increasingly recognized as an effective way to improve species distribution model (SDM) predictions by integrating biotic and abiotic information that is difficult to measure in situ. This approach appears promising for monitoring communities where biodiversity and environmental data are sparse or limited.
