Going deeper in the automated identification of Herbarium specimens [PDF]

BMC Evolutionary Biology, 2017
Hundreds of herbarium collections have accumulated a valuable heritage and knowledge of plants over several centuries. Recent initiatives started ambitious preservation plans to digitize this information and make it available to botanists and the general public through web portals.

Hemiparasitic Castilleja presence is correlated with increased plant biodiversity across montane plant communities

American Journal of Botany, EarlyView.
Abstract Premise Root hemiparasites form haustoria in belowground roots of hosts to extract nutrients and water from the surrounding hosts. Through parasitic symbiosis, these plants disproportionately affect plant communities relative to their abundance by reducing host size, altering nutrient flow, and eventually increasing local biodiversity.

Turning a new leaf: PhenoVision provides leaf phenology data at the global scale

Applications in Plant Sciences, EarlyView.
Abstract Premise Plant phenology dictates many aspects of community function and ecosystem dynamics. Yet, global phenology data are still limited, especially in areas lacking monitoring programs. Here we present a new data resource, PhenoVision–Leaf, which extends a computer vision pipeline utilizing iNaturalist digital image vouchers to produce global‐

A dormant resource for genome size estimation in ferns: C‐value inference of the Ophioglossaceae using herbarium specimen spores

Applications in Plant Sciences, 2021
Premise The great variation of genome size (C‐value) across land plants is linked to various adaptative features. Flow cytometry (FCM), the standard approach to estimating C‐values, relies mostly on fresh materials, performing poorly when used with ...

Garryanalyzer: A morphometric workflow and open‐source ImageJ plug‐in for quantitative morphological analysis of Pacific Northwest Quercus leaves

Applications in Plant Sciences, EarlyView.
Abstract Premise Accurate species identification is crucial for ecological restoration and can be especially challenging for understudied non‐model species. Quercus garryana is the only native oak species in the Pacific Northwest and is an important component of the endangered oak savanna ecosystem.

The state of herbarium specimen backlogs: Perspectives from bryophyte collections [PDF]

Natural History Collections and Museomics
An herbarium must have its specimens processed, identified and accessioned so that members of the botanical community can readily consult these materials. However, many herbaria struggle to keep up with the influx of specimens and accumulate a backlog of
