Time‐series digital camera photos combined with machine learning algorithms can realize accurate observation of flowering phenology

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Intelligent approaches are required to extract valuable phenological information from time‐series digital camera photos. In this research, we employed YOLO‐based object detection and semantic segmentation models to identify flowers and flower pixels, acquire flower count and flower cover data, and extract phenophases such as first, peak, and end ...

Classification of tree species and standing dead trees in Boreal forests using UAV‐based RGB, multispectral, and LiDAR point clouds

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
We evaluated single‐ and multi‐sensor UAV approaches for classifying tree species and standing dead trees in boreal forests, focusing on key biodiversity indicators such as European aspen. Using spectral and structural features extracted from RGB, multispectral (MSP), and LiDAR point clouds for 1,205 field‐measured trees, we compared classification ...

Epistemic Objects and Tools on the School Grounds: Addressing Plant Blindness and Knowledge Construction

open access: yesScience Education, EarlyView.
ABSTRACT Plants mediate the supply of energy and matter for all animals, including human beings yet we are faced with “plant blindness” whereby we pay limited attention to and accord little value to plants. Plant blindness is evident in school curricula whereby students have limited opportunities to learn about plants.

Bridging the Gap Between Socio‐Political and Community Acceptance of Wind Energy: Policy Insights for Sustainable Energy Development

open access: yesSustainable Development, EarlyView.
ABSTRACT Wind energy plays an important role in achieving energy transition and sustainable development goals, yet disparities between socio‐political and community acceptance continue to hinder project implementation. Understanding this gap is essential for designing more socially responsive wind energy policies.
