Scaling and balancing carbon dioxide fluxes in a heterogeneous tundra ecosystem of the Lena River Delta

, 2019
The current assessments of the carbon turnover in the Arctic tundra are subject to large uncertainties. This problem can (inter alia) be ascribed to both the general shortage of flux data from the vast and sparsely inhabited Arctic region, as well as the

Predator density outweighs experimental warming effects on short‐term carbon and nitrogen loss from arctic shrub litter

Oikos, Volume 2026, Issue 2, February 2026.
Rapid climate change in the Arctic is altering biological communities and their subsequent effects on ecosystem functioning. For example, warming‐induced shrub expansion accelerates biogeochemical cycles in part by increasing high‐quality litter inputs.

First assessment of the plant phenology index (PPI) for estimating gross primary productivity in African semi-arid ecosystems

, 2019
The importance of semi-arid ecosystems in the global carbon cycle as sinks for CO2 emissions has recently been highlighted. Africa is a carbon sink and nearly half its area comprises arid and semi-arid ecosystems.

A High‐Precision Crop Water Footprint Quantification Framework Based on Data Assimilation

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Agricultural production is a major consumer of water resources, and the crop water footprint (CWF) serves as a comprehensive metric for assessing agricultural water use efficiency and its associated impacts, thereby providing new insights for agricultural water management.

Dissolved Organic Matter Composition in the Laurentian Great Lakes Ice and Its Contribution to Spring Melt

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 2, February 2026.
Abstract Dissolved organic matter (DOM) plays a vital role in lakes, but its behavior in winter is poorly understood. This study examined the differences in DOM between lake ice and the upper water column across 18 sites in the Laurentian Great Lakes, integrating in situ sampling and remotely sensed ice data to create a mass budget model to estimate ...

Assessing the Impact of Agrivoltaics on Water, Energy, and Carbon Cycles Using the Community Land Model Version 5

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 2, February 2026.
Abstract Agrivoltaics, combining agriculture with photovoltaic systems, offers a promising solution to address land‐use conflict between food and energy production. However, the complexities of agrivoltaics and its effects on the water‐energy‐carbon interactions remain poorly understood.

Extending the air2water Model to Simulate Lake Ice Phenology, Thickness, and Composition Using Minimal Inputs

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 2, February 2026.
Abstract Ice cover in seasonally frozen lakes plays a crucial role in ecosystem dynamics and human activities, while also serving as a sensitive indicator of climate change. Accurate yet efficient modeling of lake ice timing and thickness is therefore increasingly important.
