We tested whether growth and maintenance costs of plant organs vary with environmental stress. Quercus ilex L. seedlings from acorns collected from natural populations in the northern Iberian Peninsula and in a lower elevation and putatively less stressful habitat in the southern Iberian Peninsula were grown in pots under the same conditions.

This work tests the hypothesis that growth and maintenance costs of plant organs are higher in more stressful soils. Two populations of Quercus ilex L were selected in the southern Iberian Peninsula, these growing in similar climates but different soil types, namely a brown well-developed soil on slate rock, and a stressful lithosol on gypsum rock. In both(More)
Determining the increase in maintenance respiration in response to stress is critical for understanding the cost of adaptation, in terms of expenditure of assimilated carbon. Here, we ask how maintenance costs vary for populations native to contrasting habitats and whether maintenance cost remains constitutive or induced in response to stress. Two(More)
