Biophysical probing of Spartina maritima photo-system II changes during prolong...
Duarte, B.; Santos, B.; Marques, J. C.; Caçador, I.Submergence is one of the major constrains affecting wetland plants, with inevitable impacts on their physiology and productivity. Global warming as a driving force of sea level rise, tend to increase the submersion periods duration. Photosynthesis biophysical probing arise as an important tool to understand the energetics underlying plant feedback to these constrains. As in previous studies with Spartina marit...
Tagus estuary salt marshes feedback to sea level rise over a 40-year period: In...
Duarte, B.; Caçador, I.; Marques, J. C.; Croudace, I. W.Sea level rise (SLR) has been evaluated using data acquired from two Tagus estuary salt marshes. Sediment accumulation rates over a 40-year study period were determined using 137Cs along with an evaluation of several geochemical indices and ratios as proxies of the mechisms underlying these SAR variations. Correlating SLR data from 1963 to 2001 with the sediment accretion rates (SARs) an inverse pattern of inte...
Abiotic modulation of Spartina maritima photobiology in different latitudinal p...
Duarte, B.; Couto, Thiago; Freitas, J.; Valentim, J.; Silva, H.; Marques, J. C.; Dias, J. M.; Caçador, I.Spartina maritima has a very wide distribution in the northern hemisphere salt marshes crossing a wide variety of climatic environments. Therefore, it is not strange that some differences arise when observing the photosynthetic mechanisms of different populations inhabiting different latitudes. During this study it could be observed that climate is the most important factor controlling the photosynthetic traits...
Management oriented mathematical modelling of Ria Formosa (South Portugal)
P. Duarte; B. Azevedo; C. Ribeiro; António Manuel Correia Pereira; M. Falcão; D. Serpa; R. Bandeira; J. Reia1 - Ria Formosa is a large (c.a. 100 km2) mesotidal lagoon system included in a Natural Park, with large intertidal areas and several uses such as fisheries, aquaculture, tourism and nature conservation. Its watersheds cover an area of approximately 864 km2, with a hydrographic network of small and, mostly, ephemeral rivers. 2 - The Soil and Water Assessment Tool (SWAT model) has been applied to the catchments ...
