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/aps3.1224
Abstract: Premise of the Study A novel method of estimating phenology of herbarium specimens was developed to facilitate more precise determination of plant phenological responses to explanatory variables (e.g., climate). Methods and Results Simulated specimen data… read more here.

DOI: 10.1002/aps3.1225
Abstract: Premise of the Study Herbarium specimens are increasingly used to study reproductive phenology. Here, we ask whether classifying reproduction into progressively finer‐scale stages improves our understanding of the relationship between climate and reproductive phenology. Methods… read more here.

DOI: 10.1007/s10265-019-01152-4
Abstract: Protocols for DNA extraction from plants generally involve physical and chemical destruction of tissues. Use of these conventional methods precludes preservation of morphological information from herbarium specimens, especially for small plants with few leaves, and… 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: 10.1093/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.
