Full-text available
We investigated the seasonal changes in macroinvertebrate reference communities in four Mediterranean stream types (temporary, evaporite calcareous at medium altitude, siliceous headwaters at high altitude, and calcareous headwaters at medium and high altitudes) and the interannual changes in the two headwaters stream types in Spain. Eighty-eight s...

Research in limnology is nurtured by the work of many fascinating and passionate women, who have contributed enormously to our understanding of inland waters. Female limnologists have promoted and established the bases of our knowledge about inland waters and fostered the need of protecting the values of those ecosystems. However, on numerous occas...

There is two datasets: Annex1: Table containing the name, bibliography and relevant contributions of 7...
Article
Full-text available
River conservation efforts have traditionally focused on perennial watercourses (which do not dry) and their associated aquatic biodiversity. However, most of the global river network is non‐perennial (i.e. dries at some point) and thus supports both aquatic and terrestrial biodiversity. Here, we assessed the conservation value of non‐perennial riv...

Full-text available
Dry rivers are a type of non-perennial river characterized by extreme dry conditions and dominance of terrestrial habitats. They are present in all continents, being especially abundant in arid and semiarid regions. Recent studies have shown their capacity to provide ecosystem services, although they are often undervalued and altered. This study is...
Article
Hypersaline endorheic aquatic systems (H-SEAS) are lakes/shallow playas in arid and semiarid regions that undergo extreme oscillations in salinity and severe drought episodes. Although their geochemical uniqueness and microbiome have been deeply studied, very little is known about the availability and quality of dissolved organic matter (DOM) in th...

Full-text available
Conferences are ideal platforms for studying gender gaps in science because they are important cultural events that reflect barriers to women in academia. Here, we explored women’s participation in ecology conferences by analyzing female representation, behavior, and personal experience at the 1st Meeting of the Iberian Society of Ecology (SIBECOL)...
Article
Rivers are generally considered critical habitats for biodiversity; however, this often ignores the fact that many rivers may run dry and support terrestrial as well as aquatic fauna. Here, we investigated the ecological value of intermittent rivers for terrestrial vertebrates by installing camera traps along rivers subject to varying dry periods i...
Presentation
As saline streams are geographically widespread in arid and semiarid regions, flow intermittence frequently occurs as a stressor factor in addition to salinity. Both salinity and flow intermittence are natural stressors that shape biological communities. However, we know little about the effect of drying on aquatic invertebrates and even less on te...
Poster
Both salinity and flow intermittence are natural stressors that may reduce both taxonomic and functional diversity of aquatic invertebrate communities. However, it remains unclear how drying may structure diversity of aquatic invertebrates, especially in saline streams, and even less on terrestrial invertebrate communities. Here, we examined change...

Saline streams in semi-arid regions are frequently affected by flow intermittence. Both salinity and intermittency are natural stressors that shape biological communities. However, we know little about their effects on aquatic invertebrates and even less on terrestrial invertebrate communities. Here, we examined changes in the structure and composi...
Article
Full-text available
Leaf litter can be retained in floodplains for several months before it enters rivers as lateral inputs. During this period, the environmental conditions on the floodplain can alter leaf litter chemistry and, consequently, affect its subsequent processing in the river. We analysed the effect of contrasting floodplain conditions on the chemical comp...
Conference Paper
Intermittent rivers and ephemeral streams are subject to high levels of environmental variation, shifting between aquatic and terrestrial states. These ecosystems are widespread, abundant and increasing in extent, but a proper biomonitoring program to determine their ecological quality is still lacking and challenging to develop. When rivers are dr...
Article
Full-text available
We define Dry Rivers as those whose usual habitat in space and time are dry channels where surface water may interrupt dry conditions for hours or a few days, primarily after heavy rainfall events that are variable in time and that usually lead to flash floods, disconnected from groundwater and thereby unable to harbor aquatic life. Conceptually, D...
Article
Full-text available
Many inland waters exhibit complete or partial desiccation, or have vanished due to global change, exposing sediments to the atmosphere. Yet, data on carbon dioxide (CO 2) emissions from these sediments are too scarce to upscale emissions for global estimates or to understand their fundamental drivers. Here, we present the results of a global surve...
Article
Intermittent streams are subject to high levels of environmental variation. However, little is known about how biota responds to river drying across the channel-to-upland habitat gradient. This is an important shortcoming because assumes that intermittent river habitats and metacommunities are static. Here we studied how river drying affects the sp...
Article
Debris piles and dry pools are common landscape elements along ephemeral river channels. However, their effects on resource availability and arthropod species diversity have been neglected so far. We investigated whether debris piles and pools along dry riverbeds generate nodes of environmental resources, influence microbial activity, and provide k...
Article
Full-text available
Intermittent rivers and ephemeral streams (IRES) may represent over half the global stream network, but their contribution to respiration and carbon dioxide (CO2) emissions is largely undetermined. In particular, little is known about the variability and drivers of respiration in IRES sediments upon rewetting, which could result in large pulses of...
Article
Full-text available
Climate change and human pressures are changing the global distribution and extent of intermittent rivers and ephemeral streams (IRES), which comprise half of the global river network area. IRES are characterized by periods of flow cessation, during which channel substrates accumulate and undergo physico‐chemical changes (preconditioning), and peri...
Article
Full-text available
Intermittent rivers and ephemeral streams (IRES) are dynamic ecosystems that shift between aquatic and terrestrial states. IRES are widespread, abundant and increasing in extent, but developing biomonitoring programmes to determine their ecological quality is challenging. To date, quality assessments have focused on the aquatic organisms present du...
Article
Full-text available
Perennial rivers and streams make a disproportionate contribution to global carbon (C) cycling. However, the contribution of intermittent rivers and ephemeral streams (IRES),which sometimes cease to flow and can dry completely, is largely ignored although theymay represent over half the global river network. Substantial amounts of terrestrialplant...

Conference Paper
Full-text available
Riverine ecosystems in Mediterranean climates are characterized by high levels of spatial and temporal environmental variation. This is particularly true in intermittent streams, where time-varying levels of resource availability, physical heterogeneity, and disturbance could influence biological assemblages in the riverine habitat and beyond. Howe...

Chapter
Intermittent rivers and ephemeral streams (IRES), by alternating flowing and dry phases, are coupled aquatic and terrestrial ecosystems hosting unique combinations of amphibian, reptile, bird, and mammal species (hereafter, wildlife) across different world regions. IRES are valuable ecosystems for wildlife providing essential ecological functions d...
Article
Non-perennial rivers and streams (NPRS) cover > 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 t...

Full-text available
The contribution of rare taxa to aquatic bioassessments remains a subject of debate, and generates contrasting positions among researchers. Very little is known about the effect of low-abundance taxa (LAT) for calculating both single and multimetric macroinvertebrate-based indices, as well as the ecological status classification. In this study, we...
Article
Full-text available
Riparian areas along rivers are essential movement corridors for terrestrial animals. However, the potential role of the dry bed of intermittent rivers as a movement corridor has been largely ignored. In this study, we investigated the use of the dry riverbed, compared with riparian, upland, and unpaved road habitats, by terrestrial vertebrates (ma...

Functional trait diversity can provide insight into ecosystem function beyond that provided by species diversity measures. The relationship between functional diversity and natural stressors has received less attention compared to anthropogenic stressors. In this study, we investigated how two natural stressors, water salinity and flow intermittenc...
Article
Intermittent streams are dynamic ecosystems that alternate between dry and wet states. Despite their global dominance, we have scant information about the effects of surface flow drying on terrestrial arthropods in channel and adjacent terrestrial habitats. In the present study, we used pitfall traps to characterise the terrestrial arthropod assemb...
Article
The assessment of the ecological status of water bodies, as requires by the European Water Framework Directive, can raise a number of problems when applied to temporary streams. These problems are because of the particular physical, chemical and biological conditions resulting from the recurrent cessation of flow or even the complete drying of the...
Article
Full-text available
Most streams draining to the Mediterranean basin are temporary. As a result of their hydrological regime, temporary streams are affected by drying and rewetting periods. Drying can alter in-stream nitrogen (N) availability and reduce N processing rates and subsequent retention after re-wetting. We sought to determine if hydrologic drying modifies r...

Review of temporary streams issues in Mediterranean Europe; assessing research, management and conservation needs.
Article
Full-text available
Temporary streams are those water courses that undergo the recurrent cessation of flow or the complete dry-ing of their channel. The structure and composition of biolog-ical communities in temporary stream reaches are strongly dependent on the temporal changes of the aquatic habitats determined by the hydrological conditions. Therefore, the structu...
Article
Type-specific physico-chemical reference conditions are required for the assessment of ecological status in the Water Framework Directive context, similarly to the biological and hydro-morphological elements. This directive emphasises that natural variability of quality elements in high status (reference condition) needs to be quantified. Mediterra...
Article
Mediterranean climates predispose aquatic systems to both flood and drought periods, therefore, stream sediments may be exposed to desiccation periods. Changes in oxygen concentrations and sediment water content influence the biotic processes implicated in nitrogen dynamics. The objectives of this study were to identify (1) the changes of inorganic...
