Transpirational water loss from flowers is low but unregulated

This study measures flower surface conductance across nine species and finds it is low and unresponsive to humidity changes, leading to linear water loss with vapor pressure deficit.

The effects of genome size on cell size and the functional composition and morphology of leaves: a case study in Rhododendron (Ericaceae)

This study examines how genome size affects cell size, leaf morphology, and resource acquisition in Rhododendron species, finding a tradeoff between CO2 diffusion and water retention.

Flowers are leakier than leaves but cheaper to build

The paper compares the physiological costs of flowers and leaves across species, finding flowers have higher water loss but lower carbon investment.

Mangroves deviate from other angiosperms in their genome size, leaf cell size, and cell packing density relationships

This study examines how genome size, leaf cell size, and cell packing density relate in mangroves compared to other angiosperms, finding unique adaptations in response to environmental conditions.

Diversification, disparification, and hybridization in the desert shrubs Encelia

The paper investigates diversification and disparification in Encelia, showing rapid phenotypic evolution and hybridization across environmental gradients.

Natural selection maintains species despite widespread hybridization in the desert shrub Encelia

The paper investigates how natural selection maintains species boundaries in hybridizing desert shrubs, identifying ecological mechanisms that counteract gene flow.

Emergent honeycomb topology of the leaf spongy mesophyll

The paper identifies an emergent honeycomb topology in spongy mesophyll that optimizes photosynthetic performance and resource investment across plant species.

The scaling of genome size and cell size limits maximum rates of photosynthesis with implications for ecological strategies

The paper links genome size to cell size and photosynthesis rates in plants, showing genome size predicts metabolic capacity and ecological strategies.

Energy balance implications of floral traits involved in pollinator attraction and water balance

The paper applies an energy balance model to show how flower size and color interact with physiological traits, revealing their impact on energy and temperature dynamics.

Hydraulic traits are more diverse in flowers than in leaves

The paper compares hydraulic trait diversity between flowers and leaves, finding greater diversity in flowers.
