Schismatoglottideae (Araceae) of Borneo LXXXII: Six New Species of Borneoa

open access: yesFeddes Repertorium, Volume 137, Issue 4, December 2026.
ABSTRACT Six new species of the genus Borneoa (Araceae: Schismatoglottideae) are described from Borneo, increasing the number of accepted species to 30. The new taxa are distinguished by a combination of vegetative and reproductive characters, including leaf morphology, anthomorph structure, spathe and spadix proportions, and floret details.

Short‐Term Weather Variability Alters Plant Carbon Balance in Arctic Tundra Species

open access: yesGlobal Change Biology Communications, Volume 1, Issue 4, December 2026.
With weather variability increasing due to climate change, we examined its effects on three species of Arctic plants. Short‐term variability in temperature increases average dark respiration rate while variability in light decreases average photosynthetic rate.

Pixel‐level supervision resolves overlap: Benchmarking YOLOv12 segmentation for accurate multi‐cluster dry bean stand counting from time series unoccupied aerial systems imagery

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract An agronomic trait such as stand count is important for cultivar development and crop management practices. Manually counting the number of plants is time consuming, labor‐intensive, and prone to error. The use of unoccupied aerial systems (UAS)‐collected red, green, blue (RGB) imagery in conjunction with advanced deep learning and image ...

Unmanned aerial vehicle time‐series phenotyping illuminates genotype‐specific responses to off‐target dicamba exposure in soybean

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Dicamba, a synthetic auxin herbicide, is widely used for postemergence weed control. However, the high potential for volatility and spray drift raises concerns about damage to nontarget dicot crops lacking the dicamba monooxygenase transgene, which provides bioengineered resistance.

From Prototype to Sustainable Food Production: Translational Barriers and Design Priorities for Agricultural Biosensing Systems

open access: yesJournal of Sustainable Agriculture and Environment, Volume 5, Issue 4, December 2026.
ABSTRACT Agricultural biosensors could advance sustainable food production by enabling timely detection of crop stress, pathogens, nutrient imbalances, and environmental contaminants. Despite decades of research, however, robust commercial biosensing platforms remain uncommon because analytical performance under controlled conditions does not ...

Preference‐performance relationship in the thistle tortoise beetle: Implications for its realised host range

open access: yesEcological Entomology, Volume 51, Issue 6, Page 1202-1214, December 2026.
There was a positive relationship between adult preference and larval performance. However, the strength of the relationship ranged from weak to strong depending on the measure of adult preference. The adult beetle showed substantial flexibility in host plant selection and equal performance across most thistle hosts.

Allometric relationships between lamina area, lamina mass and petiole mass of 93 temperate woody species vary with leaf habit, leaf form and altitude

open access: yes, 2008
1. The allometric scaling relationship between lamina and lamina support has rarely been examined, such that its significance to plant life-history strategies has not been fully explored and understood so far. We investigated the sizes of leaf lamina and

Lamina–petiole scaling in coordination with canopy light capture in simple‐leaved woody plants

open access: yes
Plant function relies on coordinated investment between photosynthetic tissues and structural support, yet trait‐based frameworks have largely overlooked the petiole—a key integrative organ mediating leaf mechanics and light positioning.

Divergent structure–function coordination shapes leaf thermal tolerance in Mediterranean tree species

open access: yesPlant Biology, Volume 28, Issue 7, Page 2421-2432, December 2026.
Tcrit (critical temperature) may reflect early, adaptive photoprotective downregulation of PSII in Quercus ilex, whereas in Acer campestre and Fraxinus ornus, it may more closely correspond to the onset of thermal PSII vulnerability. Abstract Increasing temperatures impair photosynthetic apparatus by damaging photosystem II (PSII) efficiency.
