Linking community structure and climate vulnerability in desert plant assemblages of southern California

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Desert plant assemblages in southern California provide an opportunity to link patterns of community structure with climate‐driven vulnerability in a rapidly changing environment. California sustains an exceptionally diverse flora of approximately 4300 plant species, with 31% identified as endemic.

Reproductive stages in lowbush blueberry (Vaccinium angustifolium) occur earlier with increasing temperature

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Climate change is altering the timing of many plant phenological events, yet most studies focus on flowering, with less attention given to later reproductive stages such as fruit development and ripening. Vaccinium angustifolium (lowbush blueberry) is an important perennial berry species that may be sensitive to these changes.

Tailoring High‐Valent Iron‐Oxo Species Redox via Extended π‐Fe3d–O2p Orbital Overlapping Toward Chemical‐Efficient Water Purification

open access: yesAngewandte Chemie, EarlyView.
We address the long‐standing challenge of reactivity–selectivity trade‐off by precisely tuning the redox properties of Fe(IV), rather than simply accelerating its formation, to enable chemically efficient and low‐emission water treatment. ABSTRACT High‐valent iron oxo species (Fe(IV)) are attractive for wastewater treatment because of their high ...

Seasonal variation in wind speed and oceanic salt spray favors delayed reproduction in coastal yellow monkeyflowers

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise The optimal timing of reproduction depends on the relative risk and benefit of continued growth. These risks and benefits depend on the local environment, which varies seasonally. While temperature and water availability are well‐studied selective agents on reproductive timing, less is known about other seasonally variable factors ...

Master narratives as “colonial propaganda” and counternarratives as “refusal”: How African Australians reimagine racial dignity in Australia

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract This paper utilizes the concept of “colonial master narratives” to examine how racial propaganda is mobilized in the Australian imaginary to “flatten” the stories of Blac/k people and how African Australians deploy counternarratives to reject these racialized projections.
