Genetic diversity and differentiation of a partial mycoheterotrophic orchid (Cymbidium macrorhizon) under urbanization

American Journal of Botany, EarlyView.
Abstract Premise Urbanization exerts substantial pressures on the genetic diversity of plant species, but the direction and magnitude of urbanization impacts may vary depending on species‐specific life history characteristics. To better understand the relationship between life history and urbanization effects, we assessed genetic diversity and ...

Spectral similarity shapes species discrimination of herbarium specimens in a taxonomically challenging group

American Journal of Botany, EarlyView.
Abstract Premise Supervised machine learning models trained on reflectance spectra are emerging as powerful tools for assisting taxonomic identification of herbarium specimens. However, it is unclear how species composition in model training affects performance.

A comprehensive review of detection, optical character recognition, and structuring methods for herbarium label digitization

Applications in Plant Sciences, EarlyView.
Abstract Global herbarium digitization has produced over 50 million specimen images, many of which contain handwritten or printed labels with rich metadata such as species names, collection dates, localities, and ecological notes. Manual transcription of this information is labor intensive, error prone, and not scalable, which has motivated the ...

Research infrastructure challenges in preparing essential biodiversity variables data products for alien invasive species

Environmental Research Letters, 2019
Essential biodiversity variables (EBV) are information products for assessing biodiversity change. Species populations EBVs are one class of EBVs that can be used to monitor the spread of invasive species.

Petal to the metal: The slow road to automating large‐scale phenology labeling for herbarium specimens

Applications in Plant Sciences, EarlyView.
Abstract Premise Herbarium specimens represent critical historical records of plant phenology, yet automating annotation of reproductive structures remains challenging given the diversity of floral morphologies, specimen age and quality, and image quality.

Are there morpho‐acoustic patterns of adaptation in nonhuman primate ears? Testing the role of ecology and habitat in shaping ear morphology and function

The Anatomical Record, EarlyView.
Abstract Analysis of the variation in the bony structures of the inner and middle ear provides critical insights into functional morphology, as well as adaptive morphology across primates. In this study, we investigated whether ear morphology patterns are related to the ecological characteristics of species and their habitats to test two acoustic ...
