The influence of rivers on seabird foraging ecology

Biological Reviews, Volume 101, Issue 4, Page 1704-1734, August 2026.
ABSTRACT Rivers act as vital arteries to the world's oceans, delivering fresh water and nutrients that sustain marine ecosystems. Globally, river flow increasingly is being altered by climate change and anthropogenic pressures; yet the significance of rivers to predatory marine species, such as seabirds, and the extent to which river‐related changes ...

Cascading River‐Lake Hydrological Regulation Reshapes Carbon Budgets of Floodplain Lakes in the Yangtze River Basin

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract The carbon budget of floodplain lakes is regulated by natural hydrological processes, yet the role of human interventions, including cascade river‐lake hydraulic projects, remains unclear. We evaluated the combined effects of the Three Gorges Dam (TGD) located on the Yangtze River and the proposed lake‐specific hydraulic projects (LHPs) on the

Riverine Biogeochemical Exports From Major Watersheds to the Northwest Patagonian Estuarine Network

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 8, August 2026.
Abstract River discharge considerably influences marine ecosystems through hydrological and biogeochemical drivers. Measuring baseline variability of riverine inputs, and their relation to anthropogenic land‐use impacts and global climate stressors affecting watersheds is therefore crucial for managing coastal marine ecosystems.

Hidden Crisis in Off‐Stream Reservoirs From Their High Sedimentation and Ageing Risks

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract Aging dams and reservoir sedimentation pose a growing threat globally. While large dams on streams dominate scientific attention, the small, especially off‐stream reservoirs are vital to rural communities but receive disproportionately less attention. This study first quantifies the proportion of off‐stream reservoirs in the United States (58%)

Calculation and analysis of water footprint of hydropower stations in Yalong River Basin

Shuili Shuiyun Gongcheng Xuebao, 2020
In order to quantify the effect of hydropower development and utilization for local water resources, this paper introduces the concept of water footprint, taking the cascade reservoirs in the Yalong River Basin as the research object, selecting the total

Airborne Observations Reveal Underestimated Riverine Methane Emissions Across the Amazon

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Strongly increasing trends in global methane in recent decades highlight the importance of understanding source‐sink attributions and climate feedback mechanisms, especially for large natural sources like wetlands. Here, we present an analysis of airborne methane observations above the Amazon Basin conducted from December 2022 through January ...
