Impacts of fire on canopy structure and its resilience depend on successional stage in Amazonian secondary forests

open access: yesRemote Sensing in Ecology and Conservation, Volume 11, Issue 4, Page 394-410, August 2025.
We analyzed the effects of fire on secondary forests' vertical structure in different successional stages using lidar metrics. Our results show that independently of the successional stage, secondary forests that experienced fire were more degraded than unburned secondary forest areas. Overall, our results show that forests in early successional stage (

Argon Cold Atmospheric Pressure Plasma‐Induced Effects on Glucose

open access: yesFood Science &Nutrition, Volume 13, Issue 7, July 2025.
This study describes the effects of cold atmospheric plasma (CAP) on glucose. Samples were treated for up to 16 min using an argon‐driven plasma device, revealing chemical modifications such as oxidation processes and ring openings on glucose. The results show that reactive plasma species led to the formation of carbonyl groups and possibly to carbon ...
