Carbon budget in a temperate estuary salt marsh. Influence of temperature incre...
Couto, Thiago Drumond Teixeira CorreiaDevido ao aumento do uso de combustíveis fósseis pelo homem desde que começou a atividade industrial, o mundo tem sofrido com o aumento do CO2 atmosférico e com o aumento da temperatura. Zonas húmidas costeiras, como os sapais são excelentes acumuladores de carbono, pois retiram CO2 da atmosfera, que se acumula nos tecidos das plantas. Modelos ecológicos têm sido utilizados para tentar entender quais os resulta...
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...
Halophytes as sources of metals in estuarine systems with low levels of contami...
Couto, Thiago; Duarte, Bernardo; Barroso, Dimitri; Caçador, I.; Marques, J. C.Heavy metal concentrations present in the above- and beowground tissues of Scirpus maritimus L., Spartina maritima (Curtis) Fernald and Zostera noltii Hornem were analysed seasonally in the Mondego Estuary, Portugal. The sediments of the estuary were confirmed to contain only low concentrations of heavy metals. The belowground tissues of all three species showed higher heavy metal concentrations than the aboveg...
