Objectivos (em Inglês):

The general objective is to understand the competition abilities and exploitation capacity of plant dunal ecosystems for water and nutrients. Particularly, this study will be focused on well preserved and disturbed coastal dune ecosystems, where the interactions of invasive and native species with environmnetal resources will be evaluated. The chosen areas (Setubal's Peninsula and S. Jacinto) will provide ideal areas for the studies, due to the variety of disturbance situations. We will use a diverse array of plant species from different successional positions (functional types). At the end of the project we expect to understand the changes caused by past plant introductions in both structure and functioning of dune ecosystems.

Objectivos (em Inglês):

The main objective of this proposal is the identification of patterns of evolution and sedimentary responses of estuarine and lagoonal environments of the SW Portuguese coast since the Late-glacial until present, using a multi- and pluridisciplinar methodology adequate to assess and separate the relative contributions of gloval vs local conditioning factors (sea-level and climate changes, sediment availability and fluvial basin changes, anthropic influence). Specific objectives are the study of past and present sedimentation patterns and rates in active or silted estuarine/lagoonal structures using a suite of proxies of geochemical and (palaeo)ecological nature, to detect paleoclimatic and palaeoenvironmnetal changes that took place throughout the last millenia. The results anticipated in this proposal link with other national studies (ongoing or submitted) on different segments of the Portuguese coast, using similar methodologies. A complementary (but of primary importance) objective is the attempt to understand, model and link process/patterns of coastal change when studied in different time-scales, ranging from the micro- to the megascale. This will be achieved through the careful examination of sedimentations products and rates, the study of the penecontemporaneous diagenetic processes affecting the sedimentary column, the study of seasonal changes of the sedimentary regime, biotic communities and physico-chemical attributes of the water, added by an evaluation of the anthropic influence in the coastal system.

Objectivos (em Inglês):

The aims of the project concern the study of two portuguese northern estuarine environments (Minho and Douro estuaries) the " meeting point" of the continental and marine influences and, in the last five thousand years, of the human action. They are a previlege local to study the natural and human actions not only the present, but also the past. The main set of problems that this project addresses are related with the way in which the above mentioned estuaries can be affected by land use, sea level and climate, and the magnitude of these impacts. The information obtained can be used to develop integrated and sustained management cirteria at regional and global scales that may have some future influence on the use of the portuguese northern coastal zone. The overall objectives are the recognition and distinction of the environmental changes (global and local, natural and man induced), which have occurred during the Late Quaternary (since 18,000 BP) and the prediction of those that are likely to occur in the future, by using a comprehensive study of the sedimentary record from estuaries of the two more important portuguese northern rivers. The project will extend the study to the continental shelf, to some large muddy-patches of continental origin in order to establish the relationship between these two environments.

Objectivos (em Inglês):

Metodologia (em Inglês):

(for the Flora survey) The vascular flora of representative communities and the total epiphytic flora (lichens and bryophytes) of Olea europaea will be studied at 40-45 representative sites around the industrial area of the CTRSU from Valorsul. The Index of Atmospheric Purity (IAP) based on floristic richness will be calculated at each site. The actual data will be annualy compared in the same area in order to detect any alteration in flora composition, caused by a general degradation of the air quality, which will be assessed by IAP zonation.

Objectivos (em Inglês):

The main objective of this work is to find traits in the spatial heterogeneity and temporal dynamics of soil properties that can be considered as triggers on processes associated with different stages of the ecological succession in Mediterranean-type ecosystems. The work has several partial objectives:

  1. to assess spatial heterogeneity and temporal dynamics of soil properties at different times along the year
  2. the comparison of spatial heterogeneity and temporal dynamics of soil properties at different places corresponding to three distinct stages of the succession; and
  3. studying the dynamic of soil properties at the scale of the individual.

Objectivos (em Inglês):

This project aimed at understanding interactions between root dynamics, associated microorganisms, climatic and edaphic conditions. Establishment of suitable mycorrhizal symbioses in the nursery is recognized as being critical for the success of tree seedlings planted out to the field environment, especially in degraded soils where the natural mycorrhizal inoculation potential is often reduced. Differing effects of mycorrhizal symbiosis on root architecture have been reported in the literaturte and the effects for these species is not known. The role of container shape in determining root system architecture was also investigated. We will test conventional "root trainers" which encourage root pruning, long narrow containers which maintain the tap root, and large columns which allow relatively unrestricted growth.

Objectivos (em Inglês):

With this project we aim at identifying biochemical and physiological indicators which may accompany productivity and precocious senescence of ammonium-grown plants. The knowledge of these mechanisms will allow a better use of nitrification inhibitors to be applied togethger with nitrogen fertilizers. The idea is to use plant species known for their different tolerance towards ammonium and evaluate their tolerance and productivity under an exclusive ammonium fertilization.

Resultados (em Inglês):

Vegetative propagation of carob trees was obtained either by micropropagation or by rooting tree cuttings. However micropropagation was much more successful, contributing to a uniform plantation trial in Spanish orchards. The rooting of cuttings was not well succeeded because the survival of plants was compromised. The optimisation of production was obtained by addition of fertilizers. However, it was also observed that Spring precipitation is crucial for the overall production rather than fertiliser addition.

Objectivos (em Inglês):

The aim of the project was to compare the tolerance of two Mediterranean species (Ceratonia siliqua and Quercus suber) to ammonium concentrations in the root medium.

Resultados (em Inglês):

Carob plants are much more tolerant to ammonium concentration in the root medium than Quercus suber. The concentrations that allowed the best growth were 1.5 and 0.5 mM respectively. Several causes of ammonium toxicity were identified, namely:

Objectivos (em Inglês):

Previous studies indicated that for eight heavy metals measured in mosses, only five of them show relation to the geological properties of the sampling sites. Also high erosion rates in some areas of Portugal may have great importance as element sources for mosses. The main objective was the qualification and quantification of the actual deposition of heavy metals in Portugal, and the determination of its regional background pattern for the 1995-1997 period.

Other objectives were:

Metodologia (em Inglês):

Sample collection took place from June 1996 to December 1997. Samples of Hypnum cupressiforme Hedw. or, whenever unavailable, Scleropodium touretii (Brid.) L. Kock were collected in a total of 132 sites covering the whole country. H. cupressiforme is a subcosmopolite and ubiquitous moss, relatively common in the region, usually found in pine forests, and S. touretii is a submediterranean species. The concentrations of Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn were determined by atomic absorption spectroscopy (graphyte furnace for Cd, Cr, Ni and flame for the other). For each heavy metal its general distribution is provided, as well as the real concentration in each moss sample, in the soil under the moss and in free soil in the same local. A multivariate analysis was performed, confirming the relation between the influence of several environmental variables and the metal distribution.

Resultados (em Inglês):

In general we can conclude that the highest Pb, Cu and Zn concentrations are found in Estremadura, Douro Litoral and Ribatejo provinces, maybe related with the high car traffic and intense industrial activities. For Cd, the highest values were observed in Estremadura. Cr, Fe and Mn were the elements more directly connected with the local geochemisty. For these elements, the highest concentrations were observed in areas with drier climate, where the soil cover is reduced and the erosion action is increased. Nevertheless, the geology, climate and ecological conditions of each studied site are the main factors, controlling/influencing the mosses contamination by soil particles. The deposition index shows the localisation of the areas with higher concentrations values around the urban regions of Lisboa and Oporto, where the population density is higher and consequently the human activities are more intense. In Baixo Alentejo and Algarve provinces, these values are probably correlated with soil contamination. Compared with northern European countries, Portugal shows high concentrations of Cd, Cr and Fe. These elements are closely related with an intensive erosion, which is characteristic of Mediterranean areas. Metals such as Cu, Ni, Pb and Zn, show values similar to other European countries. In conclusion, we can admit that the areas from Portugal with higher heavy metal concentrations, are close to urban or industrial regions from the north, centre and south, with intense car traffic.
