Crop wild relatives of the United States require urgent conservation action

The contributions of crop wild relatives (CWR) to food security depend on their conservation and accessibility for use. The United States contains a diverse native flora of CWR, including those of
important cereal, fruit, nut, oil, pulse, root...

Small herbaria contribute unique biogeographic records to county, locality, and temporal scales

With digitization and data sharing initiatives underway over the last 15 years, an important need has been prioritizing specimens to digitize. Because duplicate specimens are shared among herbaria in exchange and gift programs, we investigated the...

Caution Needed When Predicting Species Threat Status for Conservation Prioritization on a Global Scale

A widely accepted approach to assess extinction risk, and a key source of data underpinning the IPBES report, is the IUCN Red List of Threatened Species (hereafter Red List). However, with only 9%of plants represented by assessments at the latest...

Using DNA barcoding to improve invasive pest identification at U.S. ports-of-entry

Interception of potential invasive species at ports-of-entry is essential for effective biosecurity
and biosurveillance programs. However, taxonomic assessment of the immature stages
of most arthropods is challenging; characters for...

Assessing the vulnerability of Australia’s urban forests to climate extremes

Urban forests are recognized for the multiple benefits they provide to city‐dwellers.
However, climate change will affect tree species survival and persistence in urban
ecosystems. Tree failures will cause economic losses and jeopardize...

Genetic homogenisation of two major orchid viruses through global trade‐based dispersal of their hosts

Orchid viruses are capable of causing flower deformities and death, which can severely
impact the horticultural industry and wild orchid conservation. Here we show
how two of these quickly evolving viruses display few genetic differences...
