Flora and fonds: activating herbaria as archives

open access: yes, 2021
An herbarium (pl. herbaria) is a collection of botanical specimens, primarily used for identification and classification of species. While herbaria may not be structured as archives traditionally are, I will argue that the concerns of management ...

Rapid assessment of fern spore quality using microscale electrical conductivity testing

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Ex situ spore banks are essential for fern conservation and research, yet traditional germination tests for assessing spore quality are time consuming and labor intensive. We explored whether electrical conductivity (EC), a rapid proxy for seed vigor, could offer an efficient alternative for evaluating fern spore quality. Methods Using

Using herbaria to study global environmental change

open access: yes, 2018
During the last centuries, humans have transformed global ecosystems. With their temporal dimension, herbaria provide the otherwise scarce long-term data crucial to track ecological and evolutionary changes over these centuries of global change.

Nomenclatural Synopsis, Revised Distribution and Conservation Status of Ranunculus gracilis (Ranunculaceae) in Italy

open access: yesPlants, 2022
Ranuculus gracilis is endemic to the SE Euro-Mediterranean area and its presence in Italy is controversial. Based on analysis of the relevant literature, field surveys and examination of herbarium specimens, a revised distribution of this species in ...

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 ...

Extinct or Not? Confirming the “Extinct” Status of Hieracium tolstoii (Asteraceae) with Integrated Taxonomic Investigation

open access: yesDiversity
Hieracium is one of the largest flowering plant genera that has recently experienced a rapid evolutionary radiation. Due to the massive morphological variation among species, frequent hybridization, and polyploidization events, combined with apomictic ...

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.
