In this paper, an intelligent navigation system for an unmanned underwater vehicle powered by renewable energy and designed for shadow water inspection in missions of a long duration is proposed. The system is composed of an underwater vehicle, which tows a surface vehicle. The surface vehicle is a small boat with photovoltaic panels, a methanol fuel cell and comm...

Waterbirds are vital indicators of anthropogenic influence on the ecological status of Mediterranean coastal lagoons. Our study relates temporal waterbird data to key environmental gradients at catchment scale that have a structural or functional influence on littoral waterbird assemblages at different scales. During two full-year cycles and two additional wintering seasons, the nearshore water...

Climate change is supposed to remarkably affect the water resources of coastal lagoons as they are highly vulnerable to changes occurring at their catchment and/or ocean or sea boundaries. Probable impacts of projected climate changes on catchment hydrology and freshwater input were assessed using the eco-hydrological model SWIM (Soil and Water Integrated Model) for the drainage areas of four E...

The article presents a theoretical model of the entrepreneur's capacities and their influence on business performance. Starting from traditional theory dynamic capacities, those related to entrepreneurship and/or that are identified, determining factors such as training, experience confidence. In addition, other environmental institutional environment have been taken into account they affect en...

The critically endangered fan mussel Pinna nobilis, endemic to the Mediterranean Sea, faces a drastic population decline all over Sea owing an infectious disease. Coastal lagoons represent one of this species’ last reservoirs; thus, knowledge conservation status in these ecosystems is essential. An extensive monitoring programme was conducted during 2014, 2017 and 2019 Mar Menor lagoon, highly ...

Climate change is one of the main problems currently strongly conditioning ecosystems all over world. Coastal lagoons are amongst most vulnerable habitats, and they undergoing extensive human impact due to their high production rates close proximity urban agricultural centers. The Mar Menor, largest saltwater lagoon in Europe, an example a highly impacted ecosystem. In December 2016 September 2...

The present work has realized an integrated analysis of the pressures that affect state ecosystems and their services, as well management mechanisms car- ried out in two socio-ecological systems coastal lagoons located dissimilar geographical areas: socio-ecolog- ical system Mar Menor, Spain, Chiquita, Buenos Aires, Argentina. To do this, each lagoon been considered a through realization DPSIWR...

Two different methodologies were combined to evaluate the risks that antibiotics can pose in environment; i) an effect-based methodology based on microbial growth inhibition and ii) analytical method liquid-chromatography coupled mass spectrometry (LC-MS). The first approach was adapted validated for screening of four antibiotic families, specifically macrolides/β-lactams, quinolones, sulfonami...
