Diminished positive effects of warming on stability of plant productivity over time in an alpine meadow

Communications Earth & Environment
Warming can alter the temporal stability of aboveground net primary productivity (ANPP) in grasslands. However, it remains unclear how ANPP stability responds to long-term warming. Through a 10-year in-situ manipulative warming experiment conducted in an

Effect of rainfall on Artemisia ordosica Krasch anual net primary production and allocation in sandy land in China

Ecological Indicators, 2021
The adjustment of aboveground biomass allocation is an important part of plant growth adaptation strategies. Due to global climate change, rising temperatures are causing changes in global air circulation patterns.

Detection of Nitazenes in the Illicit Drug Supply Utilizing Precursor Ion Scan Methods With Paper Spray Mass Spectrometry

Drug Testing and Analysis, Volume 18, Issue 11, Page 1386-1396, November 2026.
Nitazenes are increasingly present in the illicit drug supply, complicating harm reduction efforts. We have developed a rapid, nontargeted precursor ion scan method to detect emerging nitazenes in real‐world opioid samples. The method identified multiple nitazenes, often replacing pharmaceutical opioids or mixed with fentanyl and benzodiazepines ...

Natural and land-use drivers of primary production in a highly vulnerable region of livestock production (Sierras del Este – Uruguay)

Journal of Agriculture and Rural Development in the Tropics and Subtropics, 2019
Sierras del Este is one of the two regions in Uruguay that are most vulnerable to climate change. A relevant vulnerability factor is the variability of the natural grasslands’ productivity.

Monitoring Injected Drug Use in Greece Through Syringe Residue Analysis: A Multicity Study Within the ESCAPE Network

Drug Testing and Analysis, Volume 18, Issue 11, Page 1407-1417, November 2026.
A total of 2121 used syringes were analyzed in Athens, Thessaloniki, and Patras between 2022 and 2024. Distinct drug‐use patterns were observed across the three cities. Benzodiazepines, pregabalin, methadone, and fentanyl were increasingly detected in 2024.

Using APAR to Predict Aboveground Plant Productivity in Semi-Aid Rangelands: Spatial and Temporal Relationships Differ

Remote Sensing, 2018
Monitoring of aboveground net primary production (ANPP) is critical for effective management of rangeland ecosystems but is problematic due to the vast extent of rangelands globally, and the high costs of ground-based measurements.

Microclimate, Vegetation, and Soil Response to Micro‐Zonal Solar Photovoltaic Patterning in a Humid Sub‐Tropical Agrivoltaic Grazing System

Earth's Future, Volume 14, Issue 11, November 2026.
Abstract Agrivoltaic grazing systems, or the integration of solar photovoltaic (PV) energy generation with livestock grazing, are the most common form of multi‐use solar energy in the United States and much of the world. However, there is a substantial gap in our understanding of the ecological impacts of combining PV and grazing in these novel ...

Beyond the SDG 15.3.1 Good Practice Guidance 1.0 using the Google Earth Engine platform: developing a self-adjusting algorithm to detect significant changes in water use efficiency and net primary production

Big Earth Data, 2022
Monitoring changes in Annual Net Primary Productivity (ANPP) is required for reporting on UN Sustainable Development Goal (SDG) Indicator 15.3.1: the proportion of land that is degraded over the total land area.

Increasing Ring Porous Species Composition Improves Forest Water Yield and Stabilizes Productivity

Ecohydrology, Volume 19, Issue 7, November/December 2026.
ABSTRACT Global evaporative demand is increasing and may alter plant transpiration rates, with consequences for streamflow and vegetation productivity. Tree water use can vary fourfold among species, dependent on sapwood area and xylem anatomy, and in eastern US forests, the ongoing shift from more water‐conservative oaks (Quercus) and hickories (Carya)
