Functional diversity reduces the risk of hydraulic failure in tree mixtures through hydraulic disconnection

M. Moreno, G. Simioni, H. Cochard, C. Doussan, J. Guillemot, R. Decarsin, P. Fernandez, J.-L. Dupuy, S. Trueba, F. Pimont, J. Ruffault, N. K. Martin-StPaul

This study shows that mixing drought-avoidant and drought-tolerant tree species reduces water stress during extreme drought by altering hydraulic connections.

Hydraulic adjustments of Scots pine colonizing a harsh environment on volcano slopes

T. S. Barigah, F. Dos Santos Farnese, P. E. De Menezes Silva, P. Humbert, M. Ennajeh, J. Ngao, E. Badel, H. Cochard, S. Herbette

This study examines hydraulic and leaf trait adjustments in Scots pine trees on volcano slopes under drought conditions, finding that slope trees prioritize hydraulic safety over growth.

Combined drought resistance strategies and the hydraulic limit in co-existing Mediterranean woody species

A. Alon, S. Cohen, R. Burlett, U. Hochberg, V. Lukyanov, I. Rog, T. Klein, H. Cochard, S. Delzon, R. David-Schwartz

The paper examines drought resistance strategies in Mediterranean woody species, finding interspecific variation in hydraulic and osmotic traits that lead to narrow hydraulic safety margins and risk of mortality near their distribution's dry margin.

A new mechanism for tree mortality due to drought and heatwaves

H. Cochard

The paper proposes a new mechanism for tree mortality under drought and heatwaves, suggesting excessive water loss triggers cavitation, and presents a model supporting this hypothesis.

Seasonal and long-term consequences of esca on grapevine stem xylem integrity

G. Bortolami, E. Farolfi, E. Badel, R. Burlett, H. Cochard, N. Ferrer, A. King, L. J. Lamarque, P. Lecomte, M. Marchesseau Marchal, J. Pouzoulet, J. M. Torres-Ruiz, S. Trueba, S. Delzon, G. A. Gambetta, C. E. L. Delmas

This study examines how esca disease affects xylem integrity in grapevines, showing that tyloses cause hydraulic failure in symptomatic shoots, but not in asymptomatic ones.

Modelling live fuel moisture content at leaf and canopy scale under extreme drought using SurEau-Ecos, a lumped plant hydraulic model

N. Martin-StPaul, J. Ruffault, C. Blackmann, H. Cochard, M. De Caceres, S. Delzon, J.-L. Dupuy, H. Fargeon, L. Lamarque, M. Moreno, R. Parsons, F. Pimont, J.-M. Ourcival, J. Torres-Ruiz, J.-M. Limousin

This paper uses the SurEau-Ecos model to simulate live fuel moisture content at leaf and canopy scales during drought, showing that foliage mortality and hydraulic traits drive LFMC changes.

Delayed effect of drought on the xylem vulnerability to cavitation in Fagus sylvatica L.

S. Herbette, O. Charrier, H. Cochard, T. S. Barigah

The study shows that severe drought increases xylem vulnerability to cavitation in newly formed branches of European beech saplings.

SurEau.c : a mechanistic model of plant water relations under extreme drought

H. Cochard, N. Martin-StPaul, F. Pimont, J. Ruffault

The paper introduces SurEau.c, a mechanistic model that predicts plant hydraulic failure under extreme drought by simulating water flow and conductance across plant organs.

Hypomethylated poplars show higher tolerance to water deficit and highlight a dual role for DNA methylation in shoot meristem: regulation of stress response and genome integrity

M. D. Sow, A.-L. Le Gac, R. Fichot, S. Lanciano, A. Delaunay, I. Le Jan, M.-C. Lesage-Descauses, S. Citerne, J. Caius, V. Brunaud, L. Soubigou-Taconnat, H. Cochard, V. Segura, C. Chaparro, C. Grunau, , S. Maury

This study shows hypomethylated poplars are more drought-tolerant and reveals DNA methylation's role in stress response and genome integrity in shoot meristems.

Plants resistance to drought relies on early stomata closure

N. Martin-StPaul, S. Delzon, H. Cochard

The paper challenges the assumption that stomatal closure timing is linked to embolism resistance, showing stomata close earlier in drought-resistant species, which may accelerate plant death.
