Sustainable Pd‐Catalyzed Aminations “on Dirty Water”

Angewandte Chemie, EarlyView.
Aminations, done safely yet neat, and therefore, quickly, using low levels of Pd, in “dirty water” that must contain 30% KOH; not NaOH, and not at 5%,10%, 20%, 40%, or 50% KOH. Moreover, no base sensitivity of functional groups! Very cool. Thank you, Nature.

High‐elevation endemic plants predicted to lose habitat from changing climate in Washington State

American Journal of Botany, EarlyView.
Abstract Premise High‐elevation plants face unique challenges from potential climate change impacts that will likely require upslope migration into increasingly smaller suitable habitat. This situation is particularly acute for endemic species that by definition occupy small geographic ranges.

Taxonomic reassessment of fossil Sequoia and Protosequoia from the Upper Miocene of Central Honshu, Japan, with implications for leaf morphological variation in extant S. sempervirens

American Journal of Botany, EarlyView.
Abstract Premise Since its emergence in the Mesozoic, Sequoia (Cupressaceae) has been considered to possess conserved leaf morphology. However, recent studies have shown that the leaves of extant S. sempervirens become smaller, with a scale form, with increasing tree height.

Soil salinity effects on pollen and pollinator visitation in a buzz‐pollinated glycophyte, Solanum carolinense

American Journal of Botany, EarlyView.
Abstract Premise Human activity has significantly altered the salt cycle, affecting an estimated 2.5 billion acres of soil worldwide. Elevated soil salinity is a well‐known plant stressor, but it may also affect interactions between plants and insects, which are often sodium limited.

A case of budding speciation in the California Floristic Province and infraspecific divergence in Abronia villosa

American Journal of Botany, EarlyView.
Abstract Premise Budding speciation occurs when peripheral populations adapt to local ecological conditions and “bud” off from a widespread progenitor species. Traditionally regarded as rare because of its sympatric and parapatric nature, budding speciation is largely understudied.
