Coastal dune landscapes are subject to morphological and ecological changes. In many parts of the world, coastal dunes are under severe pressure. The present study illustrates an integrated remote sensing and Geographical Information System (GIS) approach, i.e., geospatial techniques for assessing land-cover dynamics in Zouaraa coastal dunes, locat...
Monospecific pine forests are widespread due to extensive afforestation efforts and natural colonization of abandoned croplands in the Mediterranean Basin. It was originally thought that pines would facilitate the natural colonization of native late-successional resprouter species (e.g., hardwoods), but these species can be compromised if competiti...
In the climate change context, the severity and duration of drought periods are expected to increase. Forests are known to be extremely sensitive to climate change, especially in the Mediterranean Basin, and particularly in Tunisia, where climate is characterized by dry hot summers which will intensify and prolong due to climate change effects. A b...
Transpiration is a crucial component in the hydrological cycle and a key parameter in many disciplines like agriculture, forestry, ecology and hydrology. Sap flow measurements are one of the most widely used approaches to estimate whole-plant transpiration in woody species; this is due to their applicability in different environments and in a varie...
Cork oak (Quercus suber L.) is a suitable species for restoring Mediterranean ecosystems due to its capacity to resprout after wildfires and its economic importance for the use of cork. Several studies have focused on improving the seedling quality and abiotic conditions at the outplanting site to favour the field performance of Q. suber, however,...
Introduction:
Resprouter species, by regenerating rapidly, can maintain an optimal carbon balance and improve the resilience of ecosystems that have been disturbed or are at high risk of fire.
Objective:
To assess the effect of light availability and soil moisture on the ecophysiological variables of six resprouter species planted under cover of P...

Sap flow measurements are one of the most widely used methods to estimate whole-plant transpiration in woody species due to its wide application range and its ready automation for continuous data...
Assessing the vulnerability of forest ecosystems in the climate change context is a challenging task as the mechanisms that determine this vulnerability cannot be directly observed. Based on the ecological interrelationships between forests and climate, the present review focused on providing current information about vulnerability assessments of c...
Actual evapotranspiration (eta) is a key parameter to understand the soil-water balance in wild-vegetation ecosystems. Estimating the eta is, therefore, becoming increasingly important for sustainable water and land use management, particularly in water-limited
areas. This study analyses the temporal-spatial variability of eta in pine forests in a...
Forests provide many environmental services, especially those related to the water cycle. In semiarid areas where water is a limiting factor for ecosystem functioning, forested areas can have a strong impact on ground water recharge. In these areas, proper knowledge of forests’ water balance is necessary to promote management practices that may ens...
We investigated stem radial growth and water storage dynamics of two conifer species differing in hydraulic‐carbon strategies, Juniperus monosperma and Pinus edulis, under conditions of ambient, drought (∼45% reduction in precipitation), heat (∼4.8 °C temperature increase) and the combination of drought+heat, in 2013 and 2014. Juniper maintained lo...
Oak forests can naturally regenerate from seed or from sprouts. Both strategies result in the establishment of a tree layer, but they involve a crucial difference: i.e. regeneration from seeds affects population genetics while sprouting assures the recovery of biomass after a disturbance but it does not involve sexual reproduction. In addition the...

Key message
Aleppo pine stands resilience can be increased by introducing local resprouting hardwood species. Pine density management impacts seedlings establishment by modifying resources availability and abiotic stress. Under Mediterranean conditions moderate pine density should be preferred to promote seedlings establishment.

Water deficit is considered the main limiting factor for the establishment, survival, and growth of plants mainly in water-limited ecosystems. Plants have evolved a wide range of morphologic and functional mechanisms to adapt to arid environments. However, if the tension in the xylem conduits becomes too high, thus xylem cavitation can occur i.e.,...
Reforestation efforts in dryland ecosystems frequently encounter drought and limited soil productivity, although both factors usually interact synergistically to worsen water stress for outplanted seedlings. Land degradation in drylands (e.g. desertification) usually reduces soil productivity and, especially, soil water availability. In dry sub-hum...
A soil water balance model, HYDROBAL, has been used to quantify recharge in a karst aquifer under dry weather conditions. The model has also been useful to establish the importance of variables such as vegetation types and soil moisture on aquifer recharge rates. Two simulations were carried out. The first one assumes no vegetation cover, while the...
