The interplay among space, environment, and gene flow drives genetic differentiation in endemic Baja California Agave sobria subspecies

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Research on neutral and adaptive processes that lead to the divergence of species and populations is a crucial component in evolutionary and conservation genetics. Agave sobria is an endemic group of subspecies scattered on canyons along a latitudinal gradient and distinct environments of the Baja California Peninsula, Mexico.

Climatic determinants of plant phenology in vernal pool habitats

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise The floral phenology of vernal pool plants is little understood despite being a crucial developmental stage for producing seeds and determining population growth rates. Vernal pools are ephemerally aquatic habitats harboring species adapted to predictable seasonal fluctuations between desiccated and inundated conditions; thus, vernal ...

Floral scent of artificial hybrids between two Schiedea species that share a moth pollinator

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise In flowering plants, pollinators' ability to recognize chemical displays of hybrids may erode reproductive barriers. Hybrids may produce novel or altered floral scent blends that are unattractive, or scents similar to either parent that remain attractive and promote backcrossing.

In Situ/Operando Probing of Dynamic Phase Structures of Alumina‐Supported Ultrasmall Copper‐Gold Alloy Nanoparticles Under Reaction Conditions

open access: yesAngewandte Chemie, EarlyView.
Supported ultrasmall copper‐gold alloy nanoparticles are active heterogenous catalysts. In situ TEM tracking under oxygen at different temperatures reveals atomic‐scale dynamic phase structures, whereas combined operando synchrotron HE‐XRD and DRIFTS characterizations uncover ensemble‐averaged ordering/disordering phase structures and oscillatory ...

AI in Neurology: Everything, Everywhere, All at Once Part 1: Principles and Practice

open access: yesAnnals of Neurology, EarlyView.
Artificial intelligence (AI) is rapidly transforming healthcare, yet it often remains opaque to clinicians, scientists, and patients alike. This review, part 1 of a 3‐part series, provides neurologists and neuroscientists with a foundational understanding of AI's key concepts, terminology, and applications.
