Genomic structure and ex situ conservation of the North American grapevine Vitis labrusca

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
The North American wild grapevine species Vitis labrusca is an important source of disease resistance and climate resilience traits for breeding new grapevine cultivars. To ensure its continued use in breeding, V. labrusca must be accurately identified and genetically diverse material must be conserved.

Weeds in a changing climate: Competitors or service plants?

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Reducing herbicide use and preparing agroecosystems for climate change are two top priorities on the global policy agenda. Here, we explore whether these two challenges can be tackled simultaneously. While weeds are generally considered a threat to crop production, we show that weeds can help overcome climate change challenges in agroecosystems ...

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 ...

Expanding Possibilities for the Use of Writing Genres in Early Elementary Science: Investigating First‐Graders’ Multimodal Sequential Explanations

open access: yesScience Education, EarlyView.
ABSTRACT This study investigates the outcomes of the implementation of a first grade unit incorporating multiple modes of representation and genre‐based pedagogy to support writing instruction in the genre of sequential explanations. At the end of a 6‐day unit investigating the structure and functions of carnivorous plants, 47 first graders completed a
