Abstract Temporary streams are dynamic ecosystems in which mosaics of flowing, ponded and dry habitats support high biodiversity both aquatic terrestrial species. Species interact within to perform or facilitate processes that vary response changing habitat availability. A natural capital approach recognizes that, through such processes, the ‘natural assets’ all deliver services benefit people. The ecosystem temporary remain largely unexplored, particular those provided during phases. In addition, recent characterizations have focused on dryland systems, it remains unclear how service provision varies among different climatic regions, between developed developing economies. We use evidence from interdisciplinary literature examine delivered by streams, including regulating, provisioning cultural across continuum flowing conditions. focus phases wet–dry transitions, regions with contrasting climates economic development. Provision individual may be reduced, enhanced changed surface water loss. Services include higher‐quality subsurface drinking unique opportunities for recreation. Shifts wet enable groundwater recharge mitigates scarcity, grant dry‐phase access sediments deposited However, accessibility thus perceived value these other considerably regions. accessing requires careful management promote sustainable resource avoid ecological degradation. highlight need environmental managers recognize as aquatic–terrestrial ecosystems, take actions promoting their diversity functional socio‐ecological systems bundles characterized variability differing availability space time. free Plain Language Summary can found Supporting Information this article.

The concept of environmental flows (E-Flows) describes the streamflow that is necessary to maintain river ecosystems. Although a large number methods have been developed, delay was recorded in implementing E-Flows non-perennial rivers. general aim paper analyse criticalities and current state implementation rivers southern Europe. specific objectives were (i) European Union (EU) national legislation on E-Flows, (ii) methodologies currently adopted for setting EU Member States (MSs) Mediterranean Region (Spain, Greece, Italy, Portugal, France, Cyprus, Malta). From analysis legislations, it possible acknowledge step forward toward regulatory unification at level, subject more generally protection aquatic definition most countries, has abandoned idea regime constant minimal flow, but recognizes importance biological, chemical-physical aspects connected it. through review case studies, one can surmise science still an emerging discipline. limited availability hydrological, hydraulic, biological data as well restricted economic resources allocated managing are main causes MSs. results present study may contribute E-Flow

Intermittent rivers and ephemeral streams (IRES) are dynamic ecosystems that shift between aquatic terrestrial states. IRES widespread, abundant increasing in extent, but developing biomonitoring programmes to determine their ecological quality is challenging. To date, assessments have focused on the organisms present during wet phases, whereas dry-phase communities remain poorly characterized. We examined multiple biotic groups dry channels, compare assemblages at sites impacted unimpacted by human activity evaluate potential of each group as an indicator. explored existing, unpublished data for three groups: microflora (diatoms), fauna (the invertebrate 'seedbank'), a mixed flora (aquatic plants); notably, we did not source with high act indicators. Diatom plant assemblage composition differed sites, latter were more diverse included indicator taxa. Invertebrate seedbank taxa richness was higher compositional differences detected, probably due coarse taxonomic resolution which identified. Performance standard indices variable, identified conditions all groups. Our results can inform enhancement designed characterize relation legislative targets. highlight need integrate wet- survey holistic assessments. Although suggest diatoms, plants having assessment quality, research further these and, crucially, explore
