Spectral network analysis illuminates coordinated planttraits across a climate gradient

This study uses hyperspectral data and network analysis to show how plant populations adapt to climate change through coordinated trait networks rather than isolated traits.

Adaptational lag at high elevations depends on life stage in a California wildflower.

This study examines adaptational lag in high elevation populations of a wildflower, finding that survival and reproduction vary with life stage and climatic distance from the site of origin.

Herbarium specimens reveal a constrained seasonal climate niche despite diverged annual climates across a wildflower clade

The paper uses herbarium specimens to show that closely related wildflower species, despite occupying diverse annual climates, track similar seasonal climate conditions through phenological shifts and spatial refugia.

Specimen-tailored "lived" climate reveals precipitation onset and amount best predict specimen phenology, but only weakly predict estimated reproduction across a clade

The paper uses herbarium specimens to reconstruct climate conditions and assess their impact on phenology and reproduction across a plant clade, finding precipitation onset and amount best predict phenology but weakly predict reproduction.

Accelerated phenology fails to buffer fitness loss from delayed rain onset in a clade of wildflowers

The study examines how delayed rain onset affects germination timing and fitness in ten wildflower species, finding species-specific responses to climate change.

A chromosome-level genome assembly of the varied leaved jewelflower, Streptanthus diversifolius, reveals a recent whole genome duplication

This paper presents a chromosome-level genome assembly of Streptanthus diversifolius, revealing a recent whole genome duplication in the Thelypodieae tribe.
