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 ...

UAV‐based deep transfer learning to improve grain yield prediction in winter wheat across temporal and spatial variability

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Accurate prediction of grain yield (GY) remains a major challenge in plant breeding due to complex interactions between genotype, environment, and management (G × E × M) factors. Remote sensing data from unmanned aerial vehicles (UAVs) equipped with multispectral sensors have emerged as a pivotal resource for high‐throughput phenotyping.

Egg‐Carrying and Cheliceral Comb in Ibaloniinae Harvestmen From the Solomon Islands (Opiliones: Podoctidae)

open access: yesAustral Entomology, Volume 65, Issue 3, August 2026.
ABSTRACT Four new species of Ibaloniinae harvestmen are described from the Solomon Islands, Melanesia. Based on the original diagnosis of Euibalonius Roewer, 1915, and description of E. maculatus (Roewer, 1915), this material appeared related to that genus. However, examination of syntype photographs of the type species E.

Flowering out of sync: Climate change alters the reproductive phenology of Terminalia paniculata in the Western Ghats of India

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1322-1333, July 2026.
Understanding how climate change impacts the plant life cycle is critical for maintaining biodiversity and ecosystem services. Our findings suggest that Terminalia paniculata Roth, a common tropical deciduous tree species in the Western Ghats, is now flowering and fruiting at more scattered times than it used to in the past.

Herbarium digitisation sheds light on historical distribution and drivers of population extinction of a peat bog specialist

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1334-1344, July 2026.
Biodiversity loss threatens ecosystem services and human well‐being. Understanding the extent and causes of changes in biodiversity over time can help protect species and their habitats. Herbaria house carefully documented and curated specimens collected by generations of botanists.

Life after herbarium digitisation: Physical and digital collections, curation and use

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1029-1041, July 2026.
Societal Impact Statement Collections of dried plant specimens (herbaria) provide an invaluable resource for the study of many areas of scientific interest and conservation globally. Digitisation increases access to specimens and metadata, enabling efficient use across a broad spectrum of research.
