Multiscale intraspecific variation and coordination of hydraulic traits in silver fir

Belén Acuña-Míguez, Alice Copie, François Lefèvre, Maurizio Mencuccini et autres

Abstract Intraspecific variability in hydraulic and morphological traits may alter projections of forest vulnerability to climate change. Recognizing multiscale nature is essential, as trait relationships within populations may not reflect those across the species’ range. We assessed variability in 11 traits in …

Physiology of Pinus taeda: an Ice Age legacy? Intraspecific variability in drought-related physiological traits among provenances from east and west of the Mississippi River Valley

Elisabeth Ilinca, William M. Hammond, Andrew Cinquini, José M. Torres-Ruiz et autres

Human activities are increasing temperatures and reducing water availability, intensifying climate variability and extremes including heat waves and droughts, which threaten forest ecosystems. Here, we characterize and model intraspecific variability in physiological traits related to resistance to hotter droughts in loblolly pine …

Die or survive from drought? The role of cambium integrity in saplings resilience

Marylou Mantova, Jansen Steven, Hervé Cochard, Claire Szczepaniak et autres

Hydraulic failure has been causally linked to cellular damage at the leaf level, yet the functional pathway connecting xylem dysfunction to whole-tree mortality remains unresolved. One recent hypothesis is that tree death ultimately depends on the loss of meristem vitality. However, because …

Water availability shapes drought-tolerance strategies in forest phytophysiognomies in the Brazilian savanna

M Gomes da Silva, Paulo Eduardo Menezes‐Silva, Lucas Loram Lourenço, Emanuelly de Oliveira Mecenas et autres

BACKGROUND AND AIMS: Water availability strongly influences plant survival and distribution in the Cerrado, but many species co-occur in contrasting phytophysiognomies (Gallery vs. Seasonal Semideciduous Forest). This study aimed to assess whether individuals of the same species, growing in environments with contrasting …
