Asarum subspecies identification with pattern recognition techniques

, 2011
Chinese medicine pharmacologists examine the chemical features of Chinese medicine materials for identification of the subspecies. In this paper, three different types of chemical data, namely main constituent content, inorganic element content and HPLC ...

Single and dual RPA‐CRISPR/Cas assays for point‐of‐need detection of Stewart's wilt pathogen (Pantoea stewartii subsp. stewartii) of corn and Maize dwarf mosaic virus

Pest Management Science, Volume 81, Issue 4, Page 1988-1999, April 2025.
Schematic diagram of the single and dual RPA‐CRISPR/Cas12a/13a diagnostic assays for the detection of Pantoea stewartii subsp. stewartii and Maize dwarf mosaic virus. The validated assays provide a useful and sensitive molecular tool for detecting two quarantine pathogens of maize within a minimal resource framework suitable for fast‐tracking the ...

Avian Subspecies: Summary and Prospectus [PDF]

, 2010
The 14 papers in this monograph represent the first broad-based evaluation of avian subspecies in decades and one of few, if any, multifaceted treatments of subspecies for any taxon. As such, there are multiple points of agreement and disagreement.

Deep learning‐based super‐resolution reconstruction and improved YOLOv9 for efficient benthos detection: a case study at Lake Hamana, Japan

Remote Sensing in Ecology and Conservation, EarlyView.
This study presents a UAV‐based framework that integrates deep learning‐based super‐resolution reconstruction and an enhanced YOLO detector to improve centimetre‐scale benthic organism monitoring. Using hermit crabs in Lake Hamana, a coastal lagoon in Japan, as a case study, the method substantially enhanced small‐object detection performance ...

Ground‐based robotic remote sensing for standardized biodiversity monitoring in coastal habitats

Remote Sensing in Ecology and Conservation, EarlyView.
Illustrated workflow of the proposed citizen‐to‐robot monitoring pipeline: (i) expert‐validated citizen observations are translated into AI models, (ii) deployed on a ground‐based robotic platform for proximal sensing of coastal dune habitats, (iii) enabling standardized detection of ecological targets (e.g., Pancratium maritimum & Brithys crini), and (

Synthetic Imagery Improves Ecological Classification When Real Data Are Scarce, Not Direct Substitutes

Remote Sensing in Ecology and Conservation, EarlyView.
Image generation models can create synthetic ecological datasets and potentially alleviate limitations from sparse real data. Using 20 tree genera across community‐science and street‐view imagery, we tested whether synthetic images could replace or supplement real data for image classification.

In Situ Construction of Phosphorus‐Containing Crosslinked Urethane Network Combined With Ammonium Polyphosphate via Reactive Blending for Enhancing Flame Retardancy and Anti‐Dripping Performance of Polylactic Acid Composites

Safety Science and Technology, EarlyView.
By in situ reaction blending, DOPO‐HQ and THEIC were added to PLA with MDI to construct a phosphorus containing polyurethane network, which significantly improved the flame retardant and anti‐dripping properties of polylactic acid composites. ABSTRACT Polylactic acid (PLA) is highly flammable and prone to severe melt dripping during combustion, which ...

Modelling the surprising recolonisation of an understudied aquatic mammal in a highly urbanised area: fortune favoured the smooth‐coated otter in Singapore

Wildlife Biology, EarlyView.
Ever‐growing human activities present an active and continuing threat to many species throughout the world. Nevertheless, concerted conservation efforts in some regions have balanced these threats and allowed endangered species to recolonise former parts of their original ranges and reverse their decline.
