Integrated water management and the application of ecohydrological nature-based solutions, albeit modern concepts, have been part of local resources management for centuries. Exemplary for that, and recently recognized as Spain’s first UNESCO-IHP Ecohydrology demonstration site, are the so-called acequias de careo - simple groundwater recharge chan...

During the last century, the abandonment of traditional dryland farming and pastures in the Mediterranean basin promoted the development of ambitious afforestation programs causing a drastic transformation of the landscape. Afforestation programs were usually accomplished without considering the potential ecological impacts on the recipient ecosyst...

Providing historical data on riparian plant biodiversity and physico‐chemical parameters of stream water in Mediterranean mountains helps to assess the effects of climate change and other human stressors on these sensitive and critical ecosystems. This database collects data from the main natural headwater streams of the Sierra Nevada (southeastern...

Understanding how stream detritivores can cope with riparian plant invasions is relevant to predict future impacts on detritivore assemblages and the functioning of small stream ecosystems, where litter decomposition mainly fuels food webs. In a microcosm feeding trial, we examined survival, consumption, growth, and energetic status of two detritiv...

Nature-Based Solutions for Integrated Water Resources Management (NbS-IWRM) involve natural, or nature-mimicking, processes used to improve water availability in quantity and quality sustainably, reduce the risks of water-related disasters, enhance adaptation to climate change and increase both biodiversity and the social-ecological system's resili...

The spatial mapping of social-ecological system (SES) archetypes constitutes a fundamental tool to operationalize the SES concept in empirical research. Approaches to detect, map, and characterize SES archetypes have evolved over the last decade towards more integrative and comparable perspectives guided by SES conceptual frameworks and reference l...

Aim Leaf litter inputs from riparian vegetation and its decomposition play a key role in energy and nutrient transfer in many stream ecosystems. Instream leaf litter decomposition is driven by both leaf traits and environmental conditions. Therefore, understanding and predicting leaf trait variation under current environmental changes and their put...

Water availability controls the functioning of dryland ecosystems, driving a patchy vegetation distribution, unequal nutrient availability, soil respiration in pulses, and limited productivity. Groundwater-dependent ecosystems (GDEs) are acknowledged to be decoupled from precipitation, since their vegetation relies on groundwater sources. Despite t...

Water is the main limiting factor for groundwater-dependent ecosystems (GDEs) in drylands. Predicted climate change (precipitation reductions and temperature increases) and anthropogenic activities such as groundwater drawdown jeopardise the functioning of these ecosystems, presenting new challenges for their management. We developed a trait-based...

Anthropogenic impacts on freshwater ecosystems cause critical losses of biodiversity that can in turn impair key processes such as decomposition and nutrient cycling. Forest streams are mainly subsidized by terrestrial organic detritus, so their functioning and conservation status can be altered by changes in forest biodiversity and composition, pa...

The variation of plant functional traits, from the cell to the whole-plant level, is a central question in trait-based ecology with regard to understanding ecological strategies and adaptations that result from environmental drivers. Here, we analyzed whole-plant and leaf traits of the phreatophyte Ziziphus lotus (L.) Lam., a long-lived shrub that...

The linkage between leaf‐litter and macroinvertebrate shredders is pivotal for stream food webs. Global change is predicted to decrease the nutritional quality of litter inputs to streams. However, little is known about shredder's ability to develop local interpopulation adaptations to face nutrient‐depleted leaf‐litter. We hypothesized that this a...

Water is the most limiting factor in dryland ecosystems, and plants are adapted to cope with this constraint. Particularly vulnerable are phreatophytic plants from groundwater-dependent ecosystems (GDEs) in regions that have to face water regime alterations due to the impacts of climate and land-use changes. We investigated two aspects related to t...

Water is the main limiting factor for groundwater-dependent ecosystems (GDEs) in drylands. Predicted climate change (precipitation reductions and temperature increases) and anthropogenic activities such as groundwater drawdown jeopardize the structure and functioning of these ecosystems, presenting new challenges for their management. We developed...

El hábitat prioritario 5220 dominado por Ziziphus lotus ha experimentado en las últimas décadas en España un gran retroceso de su área de distribución y un grave deterioro de su funcionamiento.

In this paper, we examine the diversity and character transformation in pollen morphology and ultrastructure (of the pollen wall and aperture system) of the tribe Chelidonieae, the only Papaveraceae group including anemophilous species. Representatives of the nine Chelidonieae genera and three external species were studied using light, scanning-ele...

Riparian areas have experienced long term anthropogenic impacts including the effects of plant introductions. The giant reed (Arundo donax) is one of the most common invasive species in the riparian areas of the Iberian Peninsula (Aguiar & Ferreira, 2013). Arundo displaces native vegetation causing an impoverishment of the native flora and fauna (M...

Little is known regarding consequences of climate change on riparian plant functional types (PFTs) related to leaf traits, with putative domino effects on stream food webs, plausible even if the tipping point of stream-desiccation is not reached. We hypothesized that, as stream food-webs are highly dependent on riparian subsidies, climate change mi...

In the 1950s two Agave species, henequen (A. fourcroydes Lem.) and sisal (A. sisalana Perr.), were planted in the Parque Natural Cabo de Gata-Níjar (Almería, Spain) to produce fibers. At present, both species continue growing in this area, invading protected ecosystems. Although sterile, their mechanisms of vegetative reproduction (bulbils from sca...

Rainfall is the main limiting factor of the primary production in most of the drylands regions around the world. However, in areas dominated by phreatophytic vegetation this constraint cannot be direct. This vegetation had deep roots and is able to use groundwater, showing higher productivity than expected, particularly during the driest season of...

Studies of pollen wall development produce a great deal of morphological data that supplies useful information regarding taxonomy and systematics. We present the exine development of Euptelea and Pteridophyllum, two taxa whose pollen wall development has never previously been studied using transmission electron microscopy. Both genera are represent...
