DOI: 10.1002/ajb2.16167
Abstract: PREMISE OF THE STUDY Continental-scale leaf trait studies can help explain how plants survive in different environments, but large datasets are costly to assemble at this scale. Automating the measurement of digitized herbarium collections could… read more here.

DOI: 10.1002/aps3.11344
Abstract: Premise The ability to sequence genome‐scale data from herbarium specimens would allow for the economical development of data sets with broad taxonomic and geographic sampling that would otherwise not be possible. Here, we evaluate the… read more here.

DOI: 10.1002/aps3.1233
Abstract: Premise of the Study Phenological annotation models computed on large‐scale herbarium data sets were developed and tested in this study. Methods Herbarium specimens represent a significant resource with which to study plant phenology. Nevertheless, phenological… read more here.

DOI: 10.1007/s00035-019-00219-1
Abstract: Polyploidisation—and, additionally, agmatoploidy (concerted fission of chromosomes) in some plant groups—have significantly contributed to the diversification of alpine plant species. Both processes have driven the diversification of Luzula sect. Luzula, leading to a number of… read more here.

DOI: 10.1007/s00484-022-02238-w
Abstract: Phenology has emerged as a key metric to measure how species respond to changes in climate. Innovative means have been developed to extend the temporal and spatial range of phenological data by obtaining data from… read more here.

DOI: 10.1038/s41598-019-40050-6
Abstract: Global herbaria are the greatest repositories of information on the plant kingdom. Discoveries of trace element hyperaccumulator plants have historically required time-consuming destructive chemical analysis of fragments from herbarium specimens, which severely constrains the collection of large… read more here.

DOI: 10.1080/23818107.2017.1422437
Abstract: Abstract Perianth dimorphism in Nigella damascena (Ranunculaceae) has been documented for four centuries, and its genetic basis started to be studied almost a century ago. Based on herbarium collections, we reconstructed the evolution of the… read more here.

DOI: 10.1093/aob/mcab019
Abstract: BACKGROUND AND AIMS Fruiting remains under-represented in long-term phenology records, relative to leaf and flower phenology. Herbarium specimens and historical field notes can fill this gap, but selecting and synthesizing these records for modern-day comparison… read more here.

DOI: 10.1093/aob/mcac061
Abstract: BACKGROUND AND AIMS Habitat degradation and landscape fragmentation dramatically lower population sizes of rare plant species. Decreasing population sizes may, in turn, negatively affect genetic diversity and reproductive fitness which can ultimately lead to local… read more here.
