refloraR: An R package for efficiently retrieving and analyzing plant specimen data from the Herbário Virtual Reflora

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Advances in the digitization of herbarium collections are enabling open access to specimen data for research and conservation. In Brazil, the Herbário Virtual Reflora (HVR) hosts over 4.8 million high‐resolution images of botanical specimens and their associated data from 86 national and international herbaria.

Herbarium‐based measurements are reliable predictors of fresh plant traits in Neotropical Myrtaceae

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Herbarium specimens are increasingly used to extract morphological traits for ecological and evolutionary studies, yet the effects of tissue desiccation on trait measurements remain poorly understood. Here, we tested two hypotheses: (H1) whether higher tissue water content leads to greater measurement changes after herborization and ...

Mining buried plant trait data from the Global Biodiversity Information Facility (GBIF): Comparison and integration with multiple plant trait databases

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Despite the availability of several plant trait databases, significant traits remain undocumented for a substantial number of species. To address this issue, the current study explored digital text from the Global Biodiversity Information Facility (GBIF) as an innovative source of plant trait information and evaluated its capacity to ...

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

open access: yesApplications 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.
