“…At the stand level, sustainable harvesting aiming at reducing stand density can also result in an increased stomatal conductance that contributes to reducing drought-induced forest vulnerability , Di Matteo et al 2017. Therefore, selective thinning represents an important tool for increasing the resilience of oaks in both coppices and high-forest stands showing a high level of competition.…”

Increased forest vulnerability is being reflected as more widespread and severe drought-induced decline episodes. In particular, the Mediterranean area is revealing a high susceptibility to phenomena of loss in tree vitality across species. Within tree species, oaks (Quercus spp.) are experiencing extensive decline in many countries. However, in the wake of the so-called "oak decline phenomenon", the attention on these species has generally been limited. In this paper, we review the current available literature on oakdecline cases reported within the Mediterranean Basin, with particular remark for those occurred in Italy and Spain. More specifically our main aims were to: (i) provide an update on the patterns and mechanisms of decline by focusing on tree-ring and wood-anatomical variables; (ii) provide some hints for improving the resistance and resilience of oak stands experiencing decline. Our review reveals that drought is reported as the main driver triggering oak decline within the Mediterranean Basin, although other causes (i.e., increasing temperature, pathogens attack or excessive stand density) could exacerbate decline. In most reported cases, drought induced a substantial reduction of growth and changes in some wood anatomical properties. Indeed, growth decline prior death is also indicated as an early-warning signal of impending death. In ring-porous oak species, declining trees were often characterized by a very low production of latewood and a decrease in lumen area of the widest earlywood vessels, suggesting a potential reduction of hydraulic conductivity. Moreover, hydraulic dysfunction is reported as the main cause of decline. Finally, regarding management actions that should be considered for improving the resilience of declining stands and preserve the species-specific stand composition, it could be useful to shorten the rotation period of coppice stands or promoting their gradual conversion towards high forests, and favoring more drought-resistant species should also be considered. In addition, regeneration prior to regeneration cuts should be improved by anticipating seed dispersal or by planting oak seedlings obtained from local germoplasm.

“…Such an approach, termed “bibliometric mapping,” has been widely used to acquire a deeper understanding on the structure of the research itself. For example, it has been applied successfully to different research fields such as the evolution of chemistry research (Boyack et al, 2008), Mediterranean forest inventories (Nardi et al, 2016), and the use of stable carbon isotopes to detect the physiological impact of forest management (Di Matteo et al, 2016). To our knowledge, bibliometric mapping or science mapping has never been applied to analyze developments in plant phenotyping.…”

Modern plant phenotyping, often using non-invasive technologies and digital technologies, is an emerging science and provides essential information on how genetics, epigenetics, environmental pressures, and crop management (farming) can guide selection toward productive plants suitable for their environment. Thus, phenotyping is at the forefront of future plant breeding. Bibliometric science mapping is a quantitative method that analyzes scientific publications throughout the terms present in their title, abstract, and keywords. The aim of this mapping exercise is to observe trends and identify research opportunities. This allows us to analyze the evolution of phenotyping research and to predict emerging topics of this discipline. A total of 1,827 scientific publications fitted our search method over the last 20 years. During the period 1997–2006, the total number of publications was only around 6.1%. The number of publications increased more steeply after 2010, boosted by the overcoming of technological bias and by a set of key developments at hard and software level (image analysis and data storage management, automation and robotics). Cluster analysis evidenced three main groups linked to genetics, physiology, and imaging. Mainly the model plant “Arabidopsis thaliana” and the crops “rice” and “triticum” species were investigated in the literature. The last two species were studied when addressing “plant breeding,” and “genomic selection.” However, currently the trend goes toward a higher diversity of phenotyped crops and research in the field. The application of plant phenotyping in the field is still under rapid development and this application has strong linkages with precision agriculture. EU co-authors were involved in 41.8% of the analyzed papers, followed by USA (15.4%), Australia (6.0%), and India (5.6%). Within the EU, coauthors were mainly affiliated in Germany (35.8%), France (23.7%), and United Kingdom (18.4%). Time seems right for new opportunities to incentivize research on more crops, in real field conditions, and to spread knowledge toward more countries, including emerging economies. Science mapping offers the possibility to get insights into a wide amount of bibliographic information, making them more manageable, attractive, and easy to serve science policy makers, stakeholders, and research managers.

“…The reductions in tree density that are typically required to mitigate the risk of high-severity fire may also increase C stability during drought due to reduced water competition between trees. By increasing growing space and creating structural heterogeneity, reducing tree density can increase water availability, resulting in higher growth rates, stomatal conductance, and C assimilation compared to trees growing in unmanaged stands (Di Matteo, Nardi, & Fabbio, 2017;Giuggiola et al, 2016;Lechuga, Carraro, Viñegla, Carreira, & Linares, 2017).…”

“…The reductions in tree density that are typically required to mitigate the risk of high‐severity fire may also increase C stability during drought due to reduced water competition between trees. By increasing growing space and creating structural heterogeneity, reducing tree density can increase water availability, resulting in higher growth rates, stomatal conductance, and C assimilation compared to trees growing in unmanaged stands (Di Matteo, Nardi, & Fabbio, 2017; Giuggiola et al., 2016; Lechuga, Carraro, Viñegla, Carreira, & Linares, 2017). Additionally, recent evidence indicates that trees growing in a less competitive environment are more resilient to drought, exhibiting higher growth rates and lower mortality rates during drought events (Giuggiola, Bugmann, Zingg, Dobbertin, & Rigling, 2013; Sohn, Saha, & Bauhus, 2016; van Mantgem, Caprio, Stephenson, & Das, 2016; Vernon, Sherriff, van Mantgem, & Kane, 2018; Young et al., 2017).…”
