Factors aVecting post-Wre crown regeneration in cork oak (Quercus suber L.) trees
Cork oak (Quercus suber) forests are acknowledged for their biodiversity and economic (mainly cork production) values. WildWres are one of the main threats contributing to cork oak decline in the Mediterranean Basin, and one major question that managers face after Wre in cork oak stands is whether the burned trees should be coppiced or not. This decision can be based on the degree of expected c...
متن کاملIdentification of GPAT acyltransferases in cork oak
Background Acyltransferases are enzymes with an important role in the synthesis of both cutin and suberin which are part of the lipophilic barriers, such as epidermis and periderm that protect terrestrial plants against water loss and other external aggressions. During secondary growth in woody plants such as cork oak (Quercus suber L.), the epidermis is replaced by a suberized periderm that in...
متن کاملPhenotypic plasticity and local adaptation in leaf ecophysiological traits of 13 contrasting cork oak populations under different water availabilities.
Plants distributed across a wide range of environmental conditions are submitted to differential selective pressures. Long-term selection can lead to the development of adaptations to the local environment, generating ecotypic differentiation. Additionally, plant species can cope with this environmental variability by phenotypic plasticity. In this study, we examine the importance of both proce...
متن کاملPost-Fire Management of Cork Oak Forests
Cork oak ( Quercus suber L.) forests are def ned here as the range of habitats from open savanna-like woodland formations to dense forests. According to the European forest type’s nomenclature (EEA 2007 ) these ecosystems are included in the ‘broadleaved evergreen forest’ class and in the ‘Mediterranean e vergreen oak forest’ type. This forest type is dominated by the e vergreen sclerophyllous ...
متن کاملPlantar sensory vibration thresholds are not influenced by body position
Monitoring skin sensitivity is studied to clarify its relationship on balance. Measuring skin sensitivity is performed when subjects are sitting or lying, whereas balance tests are measured during standing. However, afferent signal processing and subsequent efferent responses can be altered by different body positions. Therefore, this study investigated whether vibration perception thresholds (...
