Sarcocornia fruticosa (L.) A.J. Scott is found in coastal marshes of south‐west Spain, growing under a very wide range interstitial soil salinity from 10 m M up to nearly 1000 . A glasshouse experiment was designed investigate the effect this salinities on morphology and photosynthetic apparatus S. by measuring growth rate, non‐photosynthetic area, atrophy distal branch ends, water status, chlorophyll fluorescence parameters, gas exchange pigment concentrations. The long‐term effects were...
Many animal species are living in urban areas, where they encounter human‐altered environmental conditions. Artificial light and traffic noise two of the most prominent anthropogenic factors, both which potentially affect life. Here we studied changes conditions over morning bird habitat city Seville, Spain. We tested experimentally whether from human activities can cause a shift timing birdsong activity. Our data revealed that vary markedly among our replicate set twelve streets. Relatively...
Summary 1 Salt marshes in south‐west Spain are being invaded by Spartina densiflora , a South American introduction, although the native S. maritima still dominates many lower marshes. A transplant experiment was used to investigate means which physical and chemical factors may determine vegetation limits tidal frame. Both species were transplanted from mid‐level marsh lower, unvegetated flats. 2 The survival growth of clumps their constituent tillers monitored on an elevational gradient....
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 sustainable saline agriculture since they can massively accumulate under stressful conditions. We investigated the responses of halophyte Crithmum maritimum to increasing salinity, nutrient deficient their interaction. hypothesized that concentration compounds would increase together...
Phenotypic acclimation of individual plants and genetic differentiation by natural selection within invasive populations are two potential mechanisms that may confer fitness advantages allow to cope with environmental variation. The invasion Spartina densiflora across a wide latitudinal gradient from California (USA) British Columbia (Canada) provides model system study the underlying response substantial variation in climate other variables.We examined morphological physiological leaf...
In 2014, a DNA-based phylogenetic study confirming the paraphyly of grass subtribe Sporobolinae proposed creation large monophyletic genus Sporobolus, including (among others) species previously included in genera Spartina, Calamovilfa, and Sporobolus. Spartina have contributed substantially (and continue contributing) to our knowledge multiple disciplines, ecology, evolutionary biology, molecular biogeography, experimental biological invasions, environmental management, restoration history,...
Spartina hybrids outperform parental species, showing transgressive acclimation to extreme climates. Native S. maritima demonstrates high seasonal adaptability and invasive densiflora low physiological impact, suggesting resilience under climate change. Extreme climatic events, such as cold heat waves, are becoming more frequent, intense, prolonged due Simultaneously, alien plant species altering the composition of communities. Both change introduction pose significant threats biodiversity....
Summary We examined salt marsh development over 17 years (1984–2001) in a rapidly accreting, well‐drained lagoon of macrotidal south‐west Spain. Scattered, elevated tussocks colonizing Spartina maritima expanded radially until they either coalesced or were separated only by narrow drainage channels. recorded changes elevation the and investigated cover biomass successive species invading them. Sediment accretion produced mean annual increase tussock 3.5 cm. Sarcocornia perennis had begun to...

Abstract Species can respond to environmental pressures through genetic and epigenetic changes phenotypic plasticity, but few studies have evaluated the relationships between differentiation plasticity of plant species along changing conditions throughout wide latitudinal ranges. We studied inter‐ intrapopulation diversity (using simple sequence repeats chloroplast DNA sequencing) variability 33 traits field common‐garden measurements) for five populations invasive cordgrass Spartina...
Abstract Aim Hybridization is a common and potent mechanism of plant evolution that has the potential to be evolutionary significant in its own right, hybrids are between invasive native congeneric species. Our aims were document existence nature new Spartina arising introduced densiflora S. maritima tidal marshes Iberian Peninsula, examine actual range intertidal zone, analyse seed set hybrids. Location South‐West Peninsula. Methods Hybrids characterized using chloroplast nuclear DNA,...
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 planet. Morphological and physiological responses to light fluxes were analyzed. L. was able acclimate moderately shaded environments, showing a high phenotypic plasticity. acclimation typified increasing leaf size, biomass, area index plant height reduced stomatal density thickness....
Abstract Although salt marsh is a classic example of primary succession, the underlying mechanisms and their time‐scales are poorly understood. As succession depends on sediment accretion, amelioration abiotic conditions associated with increasing elevation suggests potential explanatory roles for facilitation, competition stress‐gradient hypothesis. We present 35‐year longitudinal study development from intertidal flat to mid‐marsh platform at Odiel Marshes in south‐western Iberia. Using...
We conducted an intercontinental biogeographic survey to analyze the effects of invasive plant species in its native and invaded ranges. Our study system included tidal wetlands colonized by Iris pseudacorus L. (yellow flag iris, Iridaceae) along salinity gradients two estuaries European (Guadalquivir Estuary) North American (San Francisco Bay-Delta hypothesized I. would impart more negative community-level impacts on diversity range compared range. results show that colonization has very...
The germination and subsequent seedling establishment of Limonium emarginatum, an endangered endemic halophyte the Strait Gibraltar, was studied under exposure to different NaCl concentrations (0, 2, 4, 6%) in a laboratory experiment. We assessed final percentage, number days first germination, mean time germinate (MTG), as well seed viability survival. Increasing salinity delayed beginning ending reduced inhibiting completely above 2% salinity. L. emarginatum exhibited greatest fresh water....
