Ecosystem based management requires assessment of human activities and generated pressures that cause physical disturbance and loss of the seabed within the Mediterranean, also accounting for the strength of their interaction. To support the implementation of Descriptor 6 of the Marine Strategy Framework Directive (MSFD), the present work aimed at...

Alignment and coordination of the Marine Strategy Framework Directive (MSFD) with other key policies is considered indispensable to accomplish its objectives. To ensure that economic activities do not generate unsustainable pressures in the marine environment, it is imperative to streamline the MSFD with the Maritime Spatial Planning Directive (MSP...

The Marine Strategy Framework Directive (2008/56/EC) aims to achieve Good Environmental Status of the European Union’s marine waters for which the EU Member States are preparing Programmes of Measures (PoMs) to coordinate policies and improve the marine environmental status. These Programmes are revised every six years, yet there is currently no co...

Marine ecosystems are under high demand for human use, giving concerns about how pressures from human activities may affect their structure, function, and status. In Europe, recent developments in mapping of marine habitats and human activities now enable a coherent spatial evaluation of potential combined effects of human activities. Results indic...

The Marine Strategy Framework Directive (MSFD) is the piece of legislation with which the EU aims to achieve Good Environmental Status (GES) of its seas. This Directive requires Member States (MSs) to set up and implement Programmes of Measures (PoMs) to achieve this goal. This paper presents a catalogue as well as the analysis of the 535 measures...

Various pollutants keep threatening the environmental status of the Mediterranean Sea, while the Marine Strategy Framework Directive requires that Good Environmental Status needs to be achieved in European Seas by 2020. Previous reviews already established that the ambition levels of national Programmes of Measures (PoMs) are low. This study focuse...

Achieving climate change (CC) resilience in a timely and efficient fashion is becoming a major priority across multiple sectors. Agricultural CC adaptation has become an integrated part of agricultural development policy throughout the EU and further. Without the timely implementation of appropriate measures, the vulnerability of highly exposed and...

The main aim of EU water policy is to ensure that a sufficient quantity of good-quality water is available for both people's needs and the environment. The Water Framework Directive (WFD), which came into force in 2000, established a framework for the assessment, management, protection and improvement of the quality of water resources across the EU...

Floating-leaved rhizophytes and pleustophytes are the first barrier to Sun’s rays and significantly affect the light regime of the water column. To evaluate these effects on light attenuation, the reflectance and transmittance spectra variability were examined according to the leaf traits within three plant groups: (1) seed plants with green abaxia...

Halophytes have developed a variety of adaptations to cope with excessive salt and other environmental constraints. These have resulted in altered leaf traits that affect the leaf optical properties and energy balance. In halophytes, there is often salt on the leaf surface due to salt aerosols and salt excretion from glandular cells. After examinin...

Key message Limestone dust altered spectral signatures of hypo-stomatal Fagus sylvatica leaves, mitigated the effect of high air temperatures, stimulated the production of chlorophylls, and reduced the amount of photo-protective compounds. Abstract Human activities and global changes to the environment result in increased concentrations of mineral...

Cyclamen purpurascens originates from the forest understorey and has variegated leaves and red abaxial epidermis. We measured the morphological and biochemical traits, and reflectance and transmittance spectra of leaves of C. purpurascens sampled through the growing season. We determined the optical properties and differences between the light-gree...

The aim of this study was to determine the traits that define the optical properties of the needles of four coniferous species: Picea abies, Picea omorika, Abies alba and Pinus sylvestris. The analysis included measurements of the needles for their morphological and anatomical aspects, reflectances at the upper and lower needle surfaces through the...

Aims We aimed at determining differences in the leaf spectral signatures of plant species groups growing in habitats along the hydrological gradient of an intermittent wetland and to define leaf traits that explain their variability. We want to contribute to the understanding of the causes for plant spectrum variability at leaf and community levels...

This contribution discusses the relationships between reflectance spectra obtained by field spectroscopy and properties of the leaves of the species that form a stand and the relation between reflectance spectra and stand characteristics. We thus investigate the reliability of conclusions made at the species levels on the basis of the reflectance s...

The amphibious plant species Sagittaria sagittifolia and Ranunculus lingua here serve as model systems to study differences in leaf optical properties of different leaf types that develop in aquatic and terrestrial environments. We aimed to determine leaf traits that explain most of the variability in the reflectance and transmittance spectra in th...

This study aimed to relate the properties of incrusted plant tissues and structures as well as biomineral concentrations and localization with leaf reflectance and transmittance spectra from 280nm to 880nm in the grasses Phragmites australis, Phalaris arundinacea, Molinia caerulea and Deschampsia cespitosa, and the sedge Carex elata. Redundancy ana...

The effect of ultraviolet-A irradiated or nonirradiated suspensions of agglomerates of titanium dioxide (TiO(2)) or silicon dioxide (SiO(2)) nanoparticles on roots of the onion (Allium cepa) has been studied. The reactive potential of TiO(2) nanoparticles, which have photocatalytic potential, and the nonphotocatalytic SiO(2) nanoparticles with the...

The leaf reflectance spectra (280–887 nm) of two heterophyllous aquatic plant species Polygonum amphibium (L.) and Nuphar luteum (L.) were compared and their relation to physical properties of the leaves examined. In P. amphibium contrasting environmental conditions along water–land gradient affected the majority of anatomical and morphological pro...

Extensive production and wide application of TiO(2) nanoparticles has stimulated research on its potential biological effects on different groups of organisms but the interaction of TiO(2) nanoparticles with higher plants remains poorly understood. We have studied the effect of TiO(2) nanoparticles on Allium cepa using a modification of the convent...
