Does the abiotic environment influence the distribution of flower and fruit colors?

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Color in flowers and fruits carries multiple functions, from attracting animal partners (pollinators, dispersers) to mitigating environmental stress (cold, drought, UV‐B). With research historically focusing on biotic interactions as selective agents, however, it remains unclear whether abiotic stressors impact flower and fruit colors ...

Sorp‐Vection‐Based Membrane Silicone Oil Purification

open access: yesAngewandte Chemie, EarlyView.
This work presents the first Sorp‐vection‐based membrane separation for silicone oil purification, coupling sorption‐driven selectivity with convective transport. Our strategy enables highly selective removal of residual cyclic siloxanes, particularly D4, overcoming the inherent trade‐offs and limitations associated with conventional membrane processes

Selection maintains floral color polymorphism in scarlet paintbrush, Castilleja coccinea, reflecting combined ecological factors

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Evolutionary theory predicts polymorphism should be rare; however, intraspecific variation in floral color is common and can be attributed to genetic drift, plasticity, or variable selection. Examining floral color polymorphism both within contact zones and across a species' range can reveal the mechanisms maintaining this variation ...

Heat drastically alters floral color and pigment composition without affecting flower conspicuousness

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Floral pigments primarily serve to attract pollinators through color display and also contribute to protection against environmental stress. Although pigment composition can be plastically altered under stress, its impact on pollinator color perception remains poorly understood.

Using community‐based system dynamics to understand connections between housing and education: A case study with implications for homelessness prevention school‐housing partnership

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract In some communities, schools and housing agencies are innovatively partnering to prevent family homelessness and protect students from the negative outcomes associated with housing hardship. While there is increasing interest in expanding the array of housing solutions via school‐housing partnership, more research is needed to understand the ...
