Photosynthetic performance was monitored during two consecutive summers in four co-occurring evergreen Mediterranean tree species growing on a south-facing rocky slope. In response to midday water stress, the drought-avoiding Pinus halepensisMill. exhibited marked stomatal closure (gs) but no changes stem potential (Ψs), whereas drought-tolerant Quercus cocciferaL., Q. ilexssp. ballota(Desf.) Samp. and Juniperus phoeniceaL. displayed declines gs Ψs. The higher resistance CO2 influx needles...
Climate change and associated environmental alterations affect plant communities, potentially decoupling links between plants their soil microbial communities. This may in turn processes like litter decomposition, an important function that controls nutrient carbon cycling as well many other ecosystem processes. Microbial decomposers have been proposed to specialize, being able easier decompose from its ‘home’ community than what is termed the home field advantage (HFA) hypothesis. We report...
Summary Quercus coccifera , a slow‐growing, evergreen oak, grows in contrasting environments the Mediterranean Basin. Habitat‐based selection may have promoted divergence between populations with respect to phenotypic plasticity and genetic variability. We tested hypothesis that of Q. originating from rock outcrop, continental garrigue formation an oceanic forest would differ their plastic response light intensity. Plants these were grown acorns common garden at 100% 20% full sunlight. Light...
• Evergreen oaks from the Mediterranean basin exhibit a conservative resource-use strategy based on reduced expression of phenotypic variation (i.e. canalization). We hypothesized that genetic across closely related species is more canalized than response to environmental variation. Seedlings Quercus ilex and Q. coccifera, two important oak belong same subgenus section, were grown in contrasted light nutrient environments following factorial design. Phenotypic was explored total 75 variables...
Several recent studies have demonstrated that the expression of a cyanobacterial flavodoxin in plants can provide tolerance to wide range environmental stresses. Indeed, this strategy has been proposed as potentially powerful biotechnological tool generate multiple-tolerant crops. To determine whether specifically increased salt stress and it might also preserve legume nitrogen fixation under saline conditions, gene was introduced into model Medicago truncatula. Expression did not confer...
Photoinhibition was examined in four co-occurring Mediterranean evergreen tree species during two consecutive winters. In response to low temperatures and saturating light, Juniperus phoenicea L., Pinus halepensis Mill., Quercus coccifera L. Q. ilex ssp. ballota (Desf.) Samp. exhibited marked chronic photoinhibition, indicated by predawn maximal photochemical efficiency of photosystem II (PSII) (Fv/Fm). Low Fv/Fm values were correlated with high concentrations xanthophyll cycle components...
1. Canopy plasticity, the expression of different leaf phenotypes within crown an individual tree has complex functional and evolutionary implications that remain to be thoroughly assessed. We hypothesized it can lead disparity in how leaves positions canopy change with allometric growth population genetic structure. 2. Leaf inner outer were estimated using eight morphological physiological characters. All traits measured under field conditions six populations Olea europaea again a common...
as a long-lived sprouter, responds plastically to environmental variation. In this study, the role of foliar plasticity mechanism habitat selection and modification within canopy across contrasted habitats was characterized. An examination made differential contribution inner outer layers crown expressed in field by adult individuals its dependence on genetic factors. Within-crown variation eight traits examined nine populations dominated Q. coccifera. The difference between mean trait...
Woody plants, as sessile and long-lived organisms, are expected to have effective mechanisms for dealing with recurrent environmental stresses. In the present study, we hypothesized that phenotypic plasticity (the ability express alternative phenotypes) integration (covariation among functionally related traits) elicited in plants under stressful wind speed conditions. We investigated within-crown variation of nine vegetative traits a tree species (Olea europaea subsp. guanchica) six...
Background In the Peruvian Coastal Desert, an archipelago of fog oases, locally called lomas, are centers biodiversity and past human activity. Fog interception by a tree canopy, dominated legume tara (Caesalpinia spinosa), enables occurrence in Atiquipa lomas (southern Peru) environmental island with diverse flora high productivity. Although this forest provides essential services to local population, it has suffered 90% anthropogenic reduction area. Restoration efforts now getting under...
