BarnebyLives: An R package to create herbarium specimen labels and clean spreadsheets. [PDF]

open access: yesAppl Plant Sci
Abstract Premise Accessioning herbarium specimens is labor intensive, yet remains vital for research in ecology, evolution, and conservation. As institutional support for herbaria declines, efficient tools are needed to streamline this process. The R package BarnebyLives was developed to assist collectors by supplementing collection notes, verifying ...

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

open access: yesAppl Plant Sci
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 ...

Applying machine learning to investigate long‐term insect–plant interactions preserved on digitized herbarium specimens

open access: yesApplications in Plant Sciences, 2020
Premise Despite the economic significance of insect damage to plants (i.e., herbivory), long‐term data documenting changes in herbivory are limited. Millions of pressed plant specimens are now available online and can be used to collect big data on plant–
