UGV‐Based Precision Spraying System for Chemical Apple Blossom Thinning on Trellis Trained Canopies

Journal of Field Robotics, EarlyView.
ABSTRACT Blossom thinning is one of the key steps in apple crop load management that improves the quality of apples, reduces stress on the trees, and avoids the likelihood of biennial bearing. Conventional chemical blossom thinning such as air‐blast spraying can lead to excessive use of chemical thinner to ensure full coverage, which can also cause ...

Near real‐time monitoring of wading birds using uncrewed aircraft systems and computer vision

Remote Sensing in Ecology and Conservation, EarlyView.
Developments in aerial survey methods and computer vision models allow for wildlife population monitoring over large areas. A key limitation to these approaches for active monitoring is the slow process of converting imagery into data. Near real‐time monitoring is crucial for management decisions and ecological forecasting.

Alpine greening deciphered by forest stand and structure dynamics in advancing treelines of the southwestern European Alps

Remote Sensing in Ecology and Conservation, EarlyView.
Multidecadal satellite observations, like those from Landsat, enable the study of vegetation greenness trends at extensive spatial and temporal scales. Alpine ecosystems show significant increases in vegetation greenness, but the ecological processes driving this greening are less understood.

Georeferenced soil provenancing with digital signatures [PDF]

Scientific Reports, 2018
AbstractThe provenance or origin of a soil sample is of interest in soil forensics, archaeology, and biosecurity. In all of these fields, highly specialized and often expensive analysis is usually combined with expert interpretation to estimate sample origin.
