Using the right slope of the 970 nm absorption feature for estimating canopy water content [PDF]

open access: yes, 2009
Canopy water content (CWC) is important for understanding the functioning of terrestrial ecosystems. Biogeochemical processes like photosynthesis, transpiration and net primary production are related to foliar water.

Vulnerability to Dams of the Last Undammed Large Rivers of Southeast Asia

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT The vast majority of large Eurasian rivers are regulated by hydropower dams, but some have survived as free‐flowing rivers so far in the Arctic and along stretches of the Myanmar coast. There, the Ayeyarwady (Irrawaddy) and Salween Rivers, two of the largest rivers of Southeast Asia, provide a huge amount of sediment, nurturing floodplains and

Identification of initial vegetation and habitat changes in small temperate fens using remote sensing

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Temperate fens with only incipient, subtle signs of deterioration can be reliably identified using Sentinel‐2 and aerial imagery, which sensitively detect early productivity‐related structural changes. Abstract Small temperate fens rank among the most endangered habitats in temperate Europe.

Climate‐Driven Mangrove Dieback and Recovery: A Case Study in Albert and Leichhardt Rivers, Australia

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Cycles of dieback and recovery drove mangrove forest dynamics at the Albert and Leichhardt Rivers (Gulf of Carpentaria, Queensland, Australia) over 36 years (1987–2023). Landward margins were the most affected by reduced tidal inundation when the alignment of low lunar declination suppressed tidal range and extreme El Niño phases lowered mean sea level.

Using Airborne Laser Scanning and Sentinel‐2 to Understand Subcanopy Light Regimes and Understory Diversity of Vascular Plants in Temperate Mountain Forests

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
This study demonstrates that not just Airborne Laser Scanning, but also Sentinel‐2 can effectively estimate absolute canopy cover and canopy cover heterogeneity ‐ structural metrics that determine the subcanopy light regime, found to be linked to the vascular plant species richness in the understory of temperate mountain forests.
