Understanding the leaf area is essential in plant physiology and ecological studies, as it directly influences photosynthesis, transpiration productivity. This study aimed to develop non-destructive allometric models estimate of three species from Caatinga biome: Cynophalla flexuosa, Libidibia ferrea Tabebuia aurea. A total 1293 leaves were collected these species, scanned, analysed using ImageJ software obtain their length, width, actual area. In addition, product length width was...
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...
Winter cold limits temperate plant performance, as does summer water stress in drought‐prone ecosystems. The relative impact of seasonal extremes on performance has received considerable attention for individual systems. An integrated study compiling the existing literature was needed to identify overall trends. First, we conducted a meta‐analysis impacts and winter ecophysiology three woody functional types (winter deciduous angiosperms, evergreen angiosperms conifers), including data 210...
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....
Curado, G.; Rubio-Casal, A.E.; Figueroa, E., and Castillo, J.M., 2014. Plant zonation in restored, nonrestored, preserved Spartina maritima salt marshes. This study analyzes the vegetation abiotic environment (sediment elevation, pH, redox potential, electrical conductivity) 2.5 years after marsh restoration using Sarcocornia perennis plantations Odiel Marshes (SW Iberian Peninsula) comparison with degraded Restored marshes presented higher species richness (10 spp.) than nonrestored (6 (3...
Hybridization is a frequent process that leads to relevant evolutionary consequences, but there lack of studies regarding the relationships variability response parental plant species environmental gradients and responses their hybrids at phenotypic level. We designed an experiment in which we exposed two reciprocal cordgrass hybrids, Spartina maritima × densiflora S. maritima, four salinity concentrations for 30 days. The main objectives were compare performance with parents, distinguish...
Chloride (Cl-), traditionally considered harmful for agriculture, has recently been defined as a beneficial macronutrient with specific roles that result in more efficient use of water (WUE), nitrogen (NUE), and CO2 well-watered plants. When supplied range 1-5 mM, Cl- increases leaf cell size, improves osmoregulation, reduces consumption without impairing photosynthetic efficiency, resulting overall higher WUE. Thus, adequate management nutrition arises potential strategy to increase the...
Abstract. Arthrocnemum macrostachyum is a perennial species acting as primary colonizer of salt pans in Mediterranean high marshes. Salicornia ramosissima , an annual, occurs under canopies and open areas. The aim this study was to analyse, wild populations transplant experiment, how S. population dynamics growth are affected by A. macrostachyum. environmental conditions within the patches were less stressful than areas, with lower radiation levels salinity concentrations. In inner areas...
Sedimentary abiotic environment, and concentration stock of nine metals were analyzed in vegetation sediments to evaluate the phytoremediation capacity restored Spartina maritima prairies highly polluted Odiel Marshes (SW Iberian Peninsula). Samples collected two 10 -m long rows parallel tidal line at depths (0-2 cm 2-20 cm). Metal concentrations measured by inductively coupled plasma spectroscopy. Iron, aluminum, copper, zinc most concentrated metals. Every metal, except nickel, showed...
This study compared the specific activity of phosphoenolpyruvate carboxylase (PEPC) Spartina densiflora Brongn., collected from four populations along its latitudinal distribution range. is a halophyte with C(4) photosynthesis that has very wide distribution, Patagonia to southwest Iberian Peninsula. The basis intraspecific differences in PEPC were analysed by recording phosphorylation state and amount enzyme, comparing leaf anatomy evaluating gas exchange. S. individuals had 60% higher than...
Efforts to understand why some species become successful invaders and habitats are more at risk from invasive is an important research focus in invasion ecology. With current global climate change, evaluation of the effects shade drought on cohabiting native extreme ecosystems especially important. Acacia tortilis subsp. raddiana a tree taxon arid African deserts. Prosopis glandulosa, southwestern United States Mexico, invading semiarid regions that habitat for A. t. raddiana. The aim this...
Chlorophyll a fluorescence, water potential (Ψs), and root system of Juniperus oxycedrus ssp. macrocarpa, phoenicea turbinata, Pinus pinea were studied in Mediterranean coastal dunes SW Spain during summer drought after fall rains 1999, the driest year 90's. A strong reversible depression photochemical efficiency photosystem 2 three species was recorded, which happened concomitantly with diurnal increase decrease radiation. J. phoenicea, superficial system, most affected by drought. It...
The aim of this work was to describe the physiological limitations induced under drought conditions in young sweet orange trees, including crop capability recuperate its status once re-watering, and after a water withholding. trial conducted during two consecutive months (July August) two-years old trees. Three irrigation treatments were arranged: A full treatment; (FI); low-frequency deficit-irrigation treatment (LFDI); sustained-deficit (SDI) treatment. obtained results showed that for...

Weed Research 52 , 269–276. Summary Flooding has been described as one most important environmental factors determining distribution salt marsh plants. We studied impact five water levels (from well‐drained to 8 cm deep) under controlled glasshouse conditions. The rate was ca. 60%, tending decrease...
