Australia experienced one of the most devastating and intense wildfire seasons on record in 2019–2020. One challenge is to create effective models to identify areas prone to wildfires and understand the vulnerable conditions that will lead to these catastrophic events.

Woody cover and geology as regional‐scale determinants of semi‐arid savanna stability
Savannas are vital for global biodiversity and carbon storage, yet their responses to climate change and human activity remain uncertain. Using remote sensing time series and Bayesian Linear Models, we show that drought resistance and resilience vary regionally, shaped by complex interactions between geology, woody cover, fire regimes, past climate ...

Advancing the mapping of vegetation structure in savannas using Sentinel‐1 imagery
As vegetation structure monitoring is important for the understanding and conservation of savanna ecosystems, we explored the utility of C‐band synthetic aperture radar imagery for mapping both grassland and woody vegetation structure in the Greater Serengeti‐Mara Ecosystem.

Functional feeding groups (FFGs) are key components sustaining ecosystem functioning in riverine ecosystems. In this study, we conducted an airborne imaging spectroscopy campaign and a systematic environmental DNA (eDNA) river water sampling in a 740‐km2 mountainous catchment, combined with light detection and ranging (LiDAR) point clouds, to obtain ...

Hyperspectral imaging has a limited ability to remotely sense the onset of beech bark disease
Although hyperspectral imaging is a powerful remote sensing tool, it proved ineffective in predicting the progression of beech bark disease, except in its later stages, both at the canopy and leaf levels. While some alterations in chlorophyll, water content, and canopy structure may have influenced foliar reflectance at the canopy scale, as suggested ...

Aromatic ligand exchange with 2,2‐diphenylethylamine (DPEA) and dispersion in π‐conjugated organic hosts enhance the photostability and device lifetime of near‐infrared FAPbI3 perovskite nanocrystal LEDs. This strategy suppresses energy transfer, improves quantum efficiency, and extends operational stability, offering a robust platform for stable ...

We found variable spatial and temporal patterns and predictability of plant phenological progression across 8 pronghorn ranges in Montana. We sampled potential exposure to phenology values for migrants and residents along spring movement paths and summer ranges and found that within herds and years the resident and migrant movement strategies conferred

Read the free Plain Language Summary for this article on the Journal blog. Abstract The light climate at high latitudes, in particular the extended twilight of winter and the reduced diel variation in light level in midsummer and midwinter, potentially constrains visual function and the synchronisation of temporal organisation in polar species. In this

Seasonal change in wavelength ratio of incoming solar radiation reproduced by the model. Atmospheric water vapor pressure, air mass, and clearness index are used as model variables. Abstract Solar radiation (SR) dynamics significantly influence plant growth, development, and ecosystems, serving as a primary energy source and an essential environmental ...
