Fresh waters are among the most biodiverse ecosystems globally but, at the same time, also the most threatened. Serious threats to freshwater ecosystems are, for example, habitat alteration, invasive alien species and ...
Various climatic models predict an increase in the ultraviolet (UV) radiation and a reduction in the precipitation levels reaching in the Mediterranean Basin. Exposure of plants to different levels of UV radiation and water ...
Biological invasions have become one of the most pervasive threats to native ecosystems worldwide, causing species extinctions, disrupting the functioning of ecosystems, altering the provision of critical ecosystem services ...
Macroalgal forests represent some of the most productive and biodiverse habitats on Earth. In the Mediterranean Sea, species of the genus Cystoseira sensu lato dominate the well-preserved subtidal rocky habitats where ...
This thesis aimed to assess the responses of stream biota to flow alterations, in terms of water velocity increments and reductions of discharge, and to metal pollution. The investigations performed encompassed (i) ...
Confined coastal lagoons are shallow and dynamic water bodies that play an important ecological role. Considering the severe degradation they have been facing in the last years, understanding the functioning of these ...
This thesis develops a quantitative approach to understanding and predicting the spatiotemporal distribution of biodiversity, based on a stochastic version of the theory of island biogeography. Here, I present R package ...
We study the effect of organic farming practices on several taxa in olive groves and vineyards. Sessile organisms show a stronger response to treatment, their diversity being higher in organic vineyards. Vagile organism ...
Phenotypic plasticity is the adaptive response of a genotype to presenting different types of phenotypes in response to environmental changes. These adaptive responses can contribute to a particular species being able to ...
According to the Habitats Directive (92/43/ECC) a habitat is defined as “the terrestrial or aquatic area, whether entirely natural or semi-natural, differentiated by its geographical, biotic and abiotic characteristics, ...
Humanity has always been closely linked to rivers, benefiting from their resources while producing impacts associated with their activity.Thus, river systems have been exposed to multiple stressors, which have affected the ...
Hydrological drought is a process of natural desiccation mainly due to large shortage of rainfall events. Reduced precipitations and prolonged droughts are spreading worldwide and threaten the integrity of aquatic ...
Salt marshes are considered key ecosystems for climate regulation because they have a high carbon sequestration capacity. However, most studies of carbon sequestration capacity of these ecosystems have been performed in ...
Currently, global change is promoting the spatiotemporal occurrence of temporary streams, altering fluvial ecosystem function and structure, and the ecosystem services they provide. To effectively protect fluvial ecosystems, ...
I used the metacommunity framework to dissect the relative influences of dispersal (in ecological and evolutionary timeframes), selection (driven by abiotic factors) and ecological drift on the assembly process of freshwater ...
We sampled the macrofaunal metacommunities in four networks of Mediterranean temporary ponds covering a wide range of pond sizes and different spatial extents. 1) In the smallest pond network, pond size was not related to ...
During the last years, there has been an increase in the number and intensity of disturbances, and their consequences related with global change, which have corroborated the already forecasted scenarios. One example are ...
The hay meadows in the Mediterranean region of Catalonia. Geobotanical characterisation, agri-environmental assessment, and study of the phytosociological relationships between hay meadows in Western Europe We locate ...
Mediterranean rivers are characterized by high hydrological variability and heterogeneity of habitats, placing themselves amongst arid and temperate climates, and are associated with high biological diversity. On the ...
Human exploitation of river ecosystems, together with the increasing pressure that represents climate change, is posing rivers worldwide at risk. In rivers, microorganisms are ecologically very important. Most of ...
