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.

Modifications in fire frequency impact belowground plant components in old‐growth grasslands, posing risks to their resilience

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise In edaphic old‐growth grasslands, the low nutrient content of the soil restricts plant species establishment. Additionally, fire remains an important factor in shaping vegetation structure and belowground biomass investment in old‐growth grasslands, such as the campos rupestres.

A functional trait perspective on restored temperate grassland responses to changing winter insulation and managed disturbance by fire

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Understanding how disturbance regimes influence temperate grasslands is crucial for adapting management strategies to climate change, particularly in response to the loss of winters. The interaction between disturbance and climate can alter winter soil insulation and potentially the plant community.
