The importance of forest structure for carbon fluxes of the Amazon rainforest

Environmental Research Letters, 2018
Precise descriptions of forest productivity, biomass, and structure are essential for understanding ecosystem responses to climatic and anthropogenic changes. However, relations between these components are complex, in particular for tropical forests. We

A Spatial Clustering Approach of Economic Activities: An Application to the Agribusiness Sector in Brazil's Midwest Region

Geographical Analysis, Volume 58, Issue 4, October 2026.
ABSTRACT The spatial distribution of economic activities is central to regional economics. However, empirical tools for comparing industries based on the similarity of their spatial distributions remain limited. Traditional cluster analysis typically ignores geographical distance and connectivity, while spatial methods focus on clustering places rather

Nitrogen Climate Smart: Cutting UK agricultural emissions using a farmer‐focused theory of change

Annals of Applied Biology, Volume 189, Issue 2, September 2026.
Agricultural research projects that require farmers to change land management practice to make impact must embed meaningful co‐design from the outset. This figure contrasts the more traditional top‐down approach to academic research, where research outputs weakly reach farmers and impact fades when funding for short‐term projects ends.

Effects of Temperature Peaks and Water Stress on Tropical Seed Germination: Experimental Trials With Species From Brazil's Northeastern Coastal Zone

Biotropica, Volume 58, Issue 5, September 2026.
ABSTRACT Understanding the effects of high temperatures and water deficit on germination provides valuable insights into seed stress tolerance, guiding the use of native seeds in ecological restoration. This study aimed to evaluate the effects of (1) temperature peaks and (2) water stress treatments and post‐stress recovery on the germination of some ...

Systematics of Marmosa Subgenus Micoureus With Emphasis in ‘rapposa’ Group (Didelphidae, Marmosini): Geographic Variation and Revalidation of M. budini

Zoologica Scripta, Volume 55, Issue 5, Page 681-692, September 2026.
ABSTRACT Micoureus is the most species‐rich subgenus within the genus Marmosa. Conflicting arrangements regarding the number of species comprising this subgenus have been proposed and the validity of M. budini has been debated. Here, we used an approach integrating genetic and morphological data were conducted to reanalyze the ‘rapposa’ group ...

Rapid Increases in Heat‐Driven Extreme Moisture Demand in the Southern Amazon

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Extreme vapor pressure deficit (EVPD), representing the 5% hottest and driest surface air conditions, has risen rapidly over the Southern Amazon during the dry season, especially over forested areas. Its frequency has increased by 7 ± $\pm $ 1.5% (or 11 more dry season days) per decade, and its intensity has increased at rates faster than that

Gamma Rays Signal the Vulnerability of Forest to Extreme Drought

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Extreme drought and heat are driving forest die‐off globally, yet regional‐scale mapping of subsurface water storage capacity, governing forest vulnerability, remains a major challenge. Here, we demonstrate that airborne gamma‐ray spectrometry (GRS) of potassium (40K) decay provides a powerful proxy for subsurface constraints on water ...

Global Atmospheric Circulation Reorganization Drives Contrasting Wind Regime Changes Across Hemispheric Latitudes

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract Near‐surface wind regimes govern critical Earth system processes including dust mobilization, ocean mixing, and wildfire spread, yet their multi‐decadal evolution under anthropogenic forcing remains poorly constrained. Here we quantify extreme wind frequency changes (1981–2024) using ERA5‐Land reanalysis with a monthly aggregation approach ...

Methane Emissions From Wildfires: Trends and Anomalies

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract Wildfires emit smoke particles and trace gases including greenhouse gases into the atmosphere, impacting the environment and leading to detrimental impacts on human health and economy. The estimation of spatially and temporally resolved methane emissions from biomass burning (BB) provides critical information in developing measurement‐informed
