Riparian forests from semi-arid regions with saline soils are dominated by facultative phreatophytes such as tamarisks (Tamarix spp.). Tamarisks tolerate drought and salt stress using shallow deep soil water sources depending on precipitation flow variability in ephemeral or permanent streams. Therefore, their radial growth wood anatomy would differently respond to severity stream ephemerality. To assess these responses, tree-ring-width, earlywood sapwood nutrient concentrations were measured five riparian tamarisk stands located north-eastern Spain. These sites experienced different aridity degrees near (e.g., Lanaja-dry site) streams intensively irrigated agricultural areas Valcuerna). Tree rings widest Peñaflor (2.94 mm) narrowest the driest site (1.11 mm), where tree-to-tree coherence was higher than other sites. Wet conditions during year enhanced growth, particularly most responsive Lopín, whereas elevated increased hydraulic diameter Valcuerna. In site, Ca, Cu, K Mn Valcuerna, but C N lower. Elevated Ca correspond reflect eutrophication due extensive use of fertilizers depth groundwater may be a more robust proxy drier is constrained 12-month long spring droughts.

Summary Stomatal closure during drought inhibits carbon uptake and may reduce a tree's defensive capacity. Limited availability increase mortality risk, particularly if constrains trees' capacity to rapidly produce defenses biotic attack.

Abstract Purpose of Review The capacity woody plants to cope with climate change depends on their adjustments changing environmental conditions by phenotypic plasticity or genotypic changes (i.e., local adaptation). To determine whether intraspecific trait variation (ITV) translates into resistance tolerance drought and eventually how it relates performance when facing drought, we reviewed the recent literature in plant functional traits along aridity gradients. Recent Findings At level, vary gradients, but this considered species. While ITV is ubiquitous relevant magnitude, its relationship tree case growth survival unclear very idiosyncratic. Summary varies gradients and, for several traits, comparable magnitude as interspecific variation.
