Chemical diversity and phylogenetic insights into Hawaiian ʻākia (Wikstroemia) species used in traditional fishing practices

PLANTS, PEOPLE, PLANET, EarlyView.
Traditional fishing with plant‐based piscicides is a global practice in decline, facing increasing restrictions. We investigated the chemical diversity of endemic Wikstroemia species historically used to stun or poison fish in Hawaiʻi. Using 1‐H‐NMR, principal component analysis, targeted HPLC, and target‐capture sequencing, we characterized compounds ...

A new phenological metric for use in pheno‐climatic models: A case study using herbarium specimens of Streptanthus tortuosus

Applications in Plant Sciences, 2019
Premise Herbarium specimens have been used to detect climate‐induced shifts in flowering time by using the day of year of collection (DOY) as a proxy for first or peak flowering date. Variation among herbarium sheets in their phenological status, however,

Building a genomic and herbarium biorepository for medicinal plants of the Western Ghats

PLANTS, PEOPLE, PLANET, EarlyView.
Medicinal plants support healthcare for millions of people and sustain livelihoods, yet many threatened species lack secure long‐term genetic protection. This study establishes a genomic and herbarium biorepository for medicinal plants of the Western Ghats, a global biodiversity hotspot facing intense human pressure.
