Protection of Herbarium Specimens [PDF]
Nature, 1932 THE letter from Messrs. F. K. Jackson and R. L. M. Ghose1 on the protection of herbarium specimens makes a valuable suggestion. Perhaps I may be permitted to refer readers and others interested in the subject to a paper on the “Preservation of Herbarium Specimens and Insects on Celluloid”, by Mr.

Increasing the efficiency of digitization workflows for herbarium specimens [PDF]
ZooKeys, 2012 The New York Botanical Garden Herbarium has been databasing and imaging its estimated 7.3 million plant specimens for the past 17 years. Due to the size of the collection, we have been selectively digitizing fundable subsets of specimens, making ...

Genome skimming herbarium specimens for DNA barcoding and phylogenomics
Plant Methods, 2018 Background The world’s herbaria contain millions of specimens, collected and named by thousands of researchers, over hundreds of years. However, this treasure has remained largely inaccessible to genetic studies, because of both generally limited success

Petal to the metal: The slow road to automating large-scale phenology labeling for herbarium specimens. [PDF]
Appl Plant SciAbstract 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.

Ancient DNA extraction methods for herbarium specimens: When is it worth the effort? [PDF]
Appl Plant Sci, 2022 Premise Herbaria harbor a tremendous number of plant specimens that are rarely used for molecular systematic studies, largely due to the difficulty in extracting sufficient amounts of high-quality DNA from the preserved plant material.

Biases in estimation of insect herbivory from herbarium specimens. [PDF]
Sci Rep, 2020 Information regarding plant damage by insects in the past is essential to explore impacts of climate change on herbivory. We asked whether insect herbivory measured from herbarium specimens reflects the levels of herbivory occurring in nature at the time
