Mechanisms of Surface Meltwater Ponding and Drainage on the Greenland Ice Sheet Revealed Using SkySat Imagery and Deep Learning

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Surface meltwater impacts Greenland Ice Sheet mass balance indirectly by reducing albedo and promoting hydrofracture. However, fully understanding both processes requires accurate mapping of small‐scale features such as ponds, channels, and moulins that govern meltwater formation and drainage. Here we investigate surface water dynamics at high

Estimating the botanical composition of bahiagrass–rhizoma peanut pastures using aerial multispectral imagery and deep learning

Crop Science, Volume 66, Issue 2, March/April 2026.
Abstract Estimating the botanical composition in mixed pastures is challenging due to resource‐intensive sampling methods overlooking grassland spatial variability. We aimed to (I) classify bahiagrass (Paspalum notatum Flügge) and rhizoma peanut (Arachis glabrata Benth.) in grass–legume pastures using aerial multispectral imagery and machine learning, (

A Plant‐Diversity Dark Spot at the Intersection of Three Biodiversity Hotspots: Environmental Drivers of Brassicaceae Richness in Türkiye

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Türkiye lies at the intersection of three global biodiversity hotspots yet is recognised as a global plant‐diversity "dark spot." Using > 15,000 georeferenced herbarium records and spatial regression models, we examined the environmental drivers of Brassicaceae species and endemic richness across the country. Species richness increased with topographic

Century‐long trends in plant diversity of temperate mountain vegetation are modulated along elevation gradient

Journal of Ecology, Volume 114, Issue 3, March 2026.
Resurvey studies in mountain forests of the Tatra Mountains (Central Europe) show that plant diversity has increased over the past century, particularly at lower elevations. These shifts were associated more with increased nitrogen deposition and reduced grazing pressure than with direct climate warming.

Beyond Core‐Periphery: A Multidimensional Typology of Brazilian Regional Inventive Capacity

Growth and Change, Volume 57, Issue 1, March 2026.
ABSTRACT The geography of invention in Brazil is characterized by a profound and multi‐polarised structure that extends beyond a simple core‐periphery dichotomy. This paper demonstrates this complexity through a multidimensional analysis of inventive capacity (2000–2023), operationalised along four axes—‘how much’, ‘who’, ‘how’, and ‘what’ is invented ...

Modelling the Climatic Suitability of Digitaria insularis, a Global Invasive Species, Under Climate Change Scenarios

Weed Research, Volume 66, Issue 2, March/April 2026.
ABSTRACT Grasses in the Poaceae family are major components of global ecosystems and agricultural systems, and their adaptive success has enabled some species to become highly competitive weeds. Digitaria insularis (sourgrass), a C4 perennial grass native to the Americas and now widely introduced elsewhere, has evolved herbicide resistance and poses an
