Developing and deploying an unmanned aerial system–based phenotyping program for maturity to support soybean breeding

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Soybean [Glycine max (L.) Merr.] varieties are categorized into different relative maturity groups (MGs) that correspond to the approximate region that the variety is best adapted. Maturity is an important trait that growers consider when deciding which varieties to plant and for breeders as a covariate to compare genotypes.

Interactive effects of defoliation and climate change on compensatory growth of silver birch seedlings

open access: yesSilva Fennica, 2013
Atmospheric warming increases the abundance of insect herbivores and intensifies the risk of defoliation, especially in high latitude forests. At the same time, the effects of increasing temperature and CO2 on plant responses to foliage damage are poorly

Simulated beetle defoliation on willow genotypes in mixture and monotype plantations

open access: yes, 2006
The effect of simulated beetle damage (0%, 25%, 50% and 75% mechanical defoliation) on 12 willow genotypes, grown in short-rotation coppice, was studied in a modified criss-cross experimental design.

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 ...

Time course sensor‐based phenotyping can predict Ascochyta blight disease severity in Cicer species

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Ascochyta blight is a widely occurring chickpea fungal disease that can cause severe yield loss. Breeding for crop resistance benefits from high‐throughput evaluation of plant–pathogen interactions in genotypes which can serve as sources of resistance.

RECOVERY AND GROWTH PATTERNS OF COASTAL BERMUDA GRASS AS INFLUENCED BY NITROGEN LEVEL AND DEFOLIATION FREQUENCY

open access: yesAnnals of Tropical Research, 1986
The interrelationships among residual leaf area following defoliation, leaf area development patterns and mean crop growth rates of Coastal bermuda grass as influenced by nitrogen levels (20, 50 and 100 kg/ha/mo) and defoliation frequency (2, 4, and 8 ...

Effect of intensity and frequency of defoliation on aerial growth and carbohydrate reserve levels in Acacia karroo plants.

open access: yes, 1989
Acacia karroo trees were defoliated by goats at two intensities and four frequencies; 2, 4, 8 and 12-weekly. Leaf accumulation and carbohydrate reserve levels were compared to a non-defoliated control, and to plants (defoliation controls) which were ...

Spodoptera litura (Lepidoptera: Noctuidae) Adult Abundance and Larval Host Plant Use in the Ord River Irrigation Area, Western Australia

open access: yesAustral Entomology, Volume 65, Issue 4, November 2026.
ABSTRACT Spodoptera litura (Fabricius) is a highly polyphagous lepidopteran pest; however, little is known about its seasonal population dynamics or larval host plant use in northern Australia. Improved understanding of the ecology of S. litura is increasingly important given the anticipated expansion of Bacillus thuringiensis (Bt) cotton production in

The effects of defoliation on plant community, root biomass and nutrient allocation and soil chemical properties on semi-arid steppes in northern China

open access: yes, 2012
Semi-arid steppes in northern China have severely deteriorated over the past 50 years, mostly due to improper grazing management. A defoliation experiment was conducted on a Leymus chinensis-dominated semi-arid steppe to provide guidelines of grazing ...

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

open access: yesBiological Reviews, Volume 101, Issue 5, Page 2081-2102, October 2026.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...
