“…Inadequate ecological flows together with vast hydromorphological alterations commonly amplify the effects of a variety of other stressors, such as organic and inorganic pollution, pathogens and invasive species (Vörösmarty et al, 2010), where reduced dilution plays a pivotal role (Petrovic et al, 2011). This results in the simultaneous exposure of EU-Med NPRS ecosystems in multi-stress situations which may produce novel and unfamiliar synergies and, most likely, very pronounced effects of unknown consequence (Navarro-Ortega et al, 2015).…”

Non-perennial rivers and streams (NPRS) cover N 50% of the global river network. They are particularly predominant in Mediterranean Europe as a result of dry climate conditions, climate change and land use development. Historically, both scientists and policy makers underestimated the importance of NRPS for nature and humans alike, mainly because they have been considered as systems of low ecological and economic value. During the past decades, diminishing water resources have increased the spatial and temporal extent of artificial NPRS as well as their exposure to multiple stressors, which threatening their ecological integrity, biodiversity and ecosystem services. In this paper, we provide a comprehensive overview of the structural and functional characteristics of NPRS in the European Mediterranean, and discuss gaps and problems in their management, concerning their typology, ecological assessment, legislative and policy protection, and incorporation in River Basin Management Contents lists available at ScienceDirect Science of the Total Environment j o u r n a l h o m e p a g e : w w w . e l s e v i e r . c o m / l o c a t e / s c i t o t e n vPlans. Because NPRS comprise highly unstable ecosystems, with strong and often unpredictable temporal and spatial variability -at least as far as it is possible to assess -we outline the future research needs required to better understand, manage and conserve them as highly valuable and sensitive ecosystems. Efficient collaborative activities among multidisciplinary research groups aiming to create innovative knowledge, water managers and policy makers are urgently needed in order to establish an appropriate methodological and legislative background. The incorporation of NPRS in EU-Med River Basin Management Plans in combination with the application of ecological flows is a first step towards enhancing NPRS management and conservation in order to effectively safeguard these highly valuable albeit threatened ecosystems.

“…All climatic models project future scenarios of general decreases in river flows and increases in oscillations of flow intensity in the Mediterranean Basin [220]. The increased environmental presence of emerging pollutants can also impact on forests and their services such as food and water quality [130,[221][222][223]. This is already occurring and can even increase in the immediate future, thus diminishing the provision of clean water and hydroelectric production, with unpredictable socio-economic consequences [130].…”

The increase in aridity, mainly by decreases in precipitation but also by higher temperatures, is likely the main threat to the diversity and survival of Mediterranean forests. Changes in land use, including the abandonment of extensive crop activities, mainly in mountains and remote areas, and the increases in human settlements and demand for more resources with the resulting fragmentation of the landscape, hinder the establishment of appropriate management tools to protect Mediterranean forests and their provision of services and biodiversity. Experiments and observations indicate that if changes in climate, land use and other components of global change, such as pollution and overexploitation of resources, continue, the resilience of many forests will likely be exceeded, altering their structure and function and changing, mostly decreasing, their capacity to continue to provide their current services. A consistent assessment of the impacts of the changes, however, remains elusive due to the difficulty of obtaining simultaneous and complete data for all scales of the impacts in the same forests, areas and regions. We review the impacts of climate change and other components of global change and their interactions on the terrestrial forests of Mediterranean regions, with special attention to their impacts on ecosystem services. Management tools for counteracting the negative effects of global change on Mediterranean ecosystem- services are finally discussed.

“…Singlet oxygen is produced in reaction (9) and mainly inactivated by collision with water molecules, with pseudo-first order inactivation rate constant [37]. The radical CO 3 −• is produced by reactions (5), (6) and (10) and mainly scavenged by DOM, with second-order rate constant [18]. The reactions of CO 3 −• with organic compounds mainly proceed by one-electron abstraction [38].…”
