En los últimos años se ha observado una fuerte erosión en las marismas situadas en el estuario de los ríos Odiel y Tinto (Huelva). Esta erosión es muy aparente, a simple vista, por la caída de grandes bloques de sedimento desde taludes verticales desarrollados a lo largo de los principales canales, dentro de la red de drenaje marismeña. Esta...

Limonium emarginatum es una especie endómica de los acantilados del estrecho de Gibraltar. El objetivo de este trabajo fue analizar qué factores condicionan la distribución de L. emarginatum, estudiando las especies vegetales acompañantes, así como diferentes variables del medio físico en seis poblaciones. L. emarginatum apareció principalmente...

Background and aims – The spread of invasive exotic species is one of the most important threats for salt marshes and cordgrasses (genus Spartina) are among the most invasive halophytes. Recent analyses have revealed low levels of genetic diversity within the European cordgrass Spartina patens, clarifying that it was introduced from a narrow...

Este estudio se llevó a cabo en las Marismas del Odiel (Huelva, SO España). En él se cuantifican la acreción y erosión de sedimentos en taludes desarrollados en canales intermareales y en las planicies intermareales subayacentes. Se registró una erosión generalizada de los taludes, la cual se vería potenciada por actuaciones antrópicas como el...

Invasion by the South American cordgrass Spartina densiflora Brongn. in European salt marshes is causing concern about potential impacts to native plant communities., S. densiflora colonization of mid-marsh habitats may be slowed by native Atriplex portulacoides L., but the mechanism behind this negative interaction is not known. The aim of...

Hybridization is a frequent process that leads to relevant evolutionary consequences, but there is a lack of studies regarding the relationships of the variability of the response of parental plant species to environmental gradients and the responses of their hybrids at a phenotypic level. We designed an experiment in which we exposed two...

Low and high temperatures are known as most important factors influencing plant performance and distribution. Plants of Lantana camara L. coming from two distinct geographical populations (Iberian Peninsula and Galápagos Islands) were cultivated in a common garden experiment, and their leaves were subjected to thermal treatments (from +20.0 to...

Plant invasions may be limited by low radiation levels in ecosystems such as forests. Lantana camara has been classified among the world's 10 worst weeds since it is invading many different habitats all around the planet. Morphological and physiological responses to different light fluxes were analyzed. L. camara was able to acclimate to...

Capsule Salt marsh restoration with the native halophytes Spartina maritima and Zostera noltii can lead to significant improvement in habitat, increasing bird diversity over a 2-year period. Aims To assess the evolution of the avian communities in S. maritima restored salt marshes 2 years after planting, in comparison with adjacent non-restored...

: Galapagos is a natural laboratory offering a great opportunity to study plants functional traits. This study characterises morphological and ecophysiological responses of Croton scouleri, an endemic tree that habits from humid and upper elevations to semiarid lowlands, throughout an altitudinal gradient and in a manipulative experiment....

Spartina densiflora es una gramínea procedente de Sudamérica que está invadiendo numerosas marismas mareales en el golfo de Cádiz provocando problemas muy graves para la conservación de estos ecosistemas, como la pérdida de biodiversidad. En el Campo de Gibraltar Spartina densiflora se localiza en las desembocaduras de los ríos Vega y Jara y en...

Germination and emergence of halophytes may decrease significantly by seed burial in dead plant material, or wrack, which is common and abundant in tidal marshes. The effects of plant debris (wrack) burial on seed germination and seedling establishment of Spartina densiflora, an invasive cordgrass, were studied under greenhouse conditions and...

Experimental studies to determine the nature of ecological interactions between invasive and native species are necessary for conserving and restoring native species in impacted habitats. Theory predicts that species boundaries along environmental gradients are determined by physical factors in stressful environments and by competitive ability...

Efforts to understand why some species become successful invaders and why some habitats are more at risk from invasive species is an important research focus in invasion ecology. With current global climate change, evaluation of the effects of shade and drought on cohabiting native and invasive species from extreme ecosystems is especially...

Hybridization might promote offspring fitness via a greater tolerance to environmental stressors due to heterosis and higher levels of phenotypic plasticity. Thus, analyzing the phenotypic expression of hybrids provides an opportunity to elucidate further plant responses to environmental stress. In the case of coastal salt marshes, sea level...

Soil seed banks play a critical role in the maintenance of wetland plant communities and contribute to revegetation following disturbances. Analysis of the seed bank can therefore inform restoration planning and management. Emergence from seed banks may vary in response to hydrologic conditions and sediment disturbances. To assess the...

Heavy metal contamination is an increasingly pressing global ecological concern adversely affecting plant growth. Phytoremediation is an eco-friendly and low-cost approach to help solve this problem by using plants to remove metals. This study aimed to evaluate the phytoremediation potential of four Plantago species, exposing them to different...
