El presente trabajo analiza la experiencia de aplicación de un Ciclo de Mejora Docente en la asignatura "Ciencia y Tecnología del Medio Ambiente" (Grado de Ingeniería Agrícola de la Universidad de Sevilla). El ciclo de mejora se llevó a cabo durante la impartición del bloque de contenidos titulado "Interacciones entre poblaciones", que...

Resultado de las actividades antrópicas la concentración de CO2 atmosférico ha aumentado de manera vertiginosa en el último siglo. Ante este futuro escenario de cambio, el objetivo del presente estudio ha sido evaluar la respuesta de la vegetación característica de los ecosistemas forestales mediterráneos (Quercus coccifera) bajo distinto grado...

La industrialización y los cambios en el uso del territorio han originado que la flora europea esté considerada entre las más amenazadas del planeta. A pesar de los esfuerzos realizados, los datos que se manejan actualmente en relación a un gran número de especies son insuficientes para realizar una evaluación de su estado de conservación. Un...

Lime-induced chlorosis is a widespread nutritional disorder affecting grapevines cultivated in calcareous soils. A greenhouse experiment was conducted to investigate the response of Vitis vinifera ssp. sylvestris to soil lime by evaluating the effects of a range of soil CaCO3 contents (0-60%) on plant growth, nutrient content (iron, potassium,...

We evaluate copper tolerance and accumulation in Vitis vinifera ssp. sylvestris in populations from a copper contaminated site and an uncontaminated site, and in the grapevine rootstock "41B", investigating the effects of copper (0-23. mM) on growth, photosynthetic performance and mineral nutrient content. The highest Cu treatment induced...

Tolerance of plants to elevated concentrations of heavy metals in growth media and in its tissues leads to high degrees of metal bioaccumulation, which may pose a risk for humans and animals alike. Therefore, bio-accumulating plants need thorough evaluation from an environmental health point of view. A glasshouse experiment concerning the...

Spartina densiflora Brongn. is found in coastal marshes of south-west Spain, growing in sediments with between 300 and 3000 mg Cu kg-1 total soil DW (450-4500 mg Cu kg-1 supposing that the soil porosity is 0.5). An experiment was designed to investigate the effect of copper from 0 to 5000 mg kg-1 (64 mmol l-1) on the photosynthetic apparatus...

Expansion of invasive species inducing sands stabilization is becoming an important ecological problem in coastal dunes in some parts of the world. Retama monosperma, an endemic to coasts of SE Spain and NE of Morocco, late-colonizing shrub occurring in sandy coastal areas, was planted along the coast of SW Spain during the 20th century to...

Increasing air temperatures and decreasing rainfall can alter Mediterranean ecosystems, where summer heat and drought already limit plant regeneration. Manipulative field studies can help to understand and anticipate community responses to climate changes. In a Mediterranean oak wooded pasture, we have investigated the effects of warming (W,...

Background and aims: Forecasted climate change and overgrazing are threatening the sustainability of dehesas, human-managed ecosystems where pastures, livestock and scattered trees coexist. Pasture quality is particularly sensitive to these global-change drivers, but there are still many gaps to broaden knowledge about the interactive effects...

Glaucium flavum Crantz. is a short-lived perennial herb distributed in coastal zones from the Black Sea to southern, western and north-western Europe. Despite its diminishing area of distribution and potential pharmacological value, little is known about the ecophysiological features of this coastal species. We investigated the photosynthetic...

Many plant species are being threatened by increasingly drought conditions due to current climate change at planetary scale. This global trend is leading to the scientific community to investigate the potential role of local adaptations through intraspecific differences in functional traits that may boost conservation strategies by modulating...

In this study, we evaluated changes in the potential flammability of different Mediterranean shrub species in a pine (Pinus pinea) forest in the Doñana Natural Park (of SW Spain) as a result of goat grazing. Plant height, total biomass, fine fuel biomass and leaves/wood ratio were measured in individual plants of each species in both grazed and...

Spartina densiflora is a C4 halophytic species that has proved to have a high invasive potential which derives from its clonal growth and its physiological plasticity to environmental factors, such as salinity. A greenhouse experiment was designed to investigate the synergic effect of 380 and 700 ppm CO2 at 0, 171, and 510 mM NaCl on the growth...

Increasing temperature and aridity predicted by climate change models in the Mediterranean region will pose a significant challenge for the survival of some plant species. The mechanisms by which species modify their phenotype across generations in response to the environment have been identified as essential to cope with the new climatic...

Background and Aims: Halophytic species often show seed dimorphism, where seed morphs produced by a single individual may differ in germination characteristics. Particular morphs are adapted to different windows of opportunity for germination in the seasonally fluctuating and heterogeneous salt-marsh environment. The possibility that plants...

Abstract: The ecosystem services provided by the age-old activity of husbandry are presently de- clining or seriously endangered. The situation is particularly serious for regulation services and for certain cultural services given their growing dependence on external inputs. This work performs a bibliometric analysis for the purpose of...

Aims: Soil abiotic factors influence plant defensive traits by shaping the costs of defence production and these bottom-up effects on plants can in turn affect insect herbivory. However, few studies have disentangled direct and indirect effects of soil abiotic factors on plant defences and insect herbivory. Methods: To address this gap, we...

Las marismas son ecosistemas frontera entre los medios terrestre y costero, que se distribuyen a lo largo de los estuarios de latitudes medias y altas de todo el mundo. Se trata de ecosistemas de gran importancia tanto ecológica como medioambiental y socio-económica. A pesar de la importancia de las marismas, son ecosistemas con graves...

Climate change, characterised by drought events and rising temperatures, exerts a significant threat to crop productivity and global food security. Halophytes, known for their resilience in harsh conditions, offer promising options for sustainable cultivation alternatives. Our study focused on Crithmum maritimum, commonly known as sea fennel,...

Plant bioactive metabolites play a pivotal role in protection against environmental stresses and offer great potential for nutraceutical exploitation. In this sense, halophytes present an exceptional opportunity for sustainable saline agriculture since they can massively accumulate bioactive metabolites under stressful conditions. We...
