Response of a benthic sargassum population to increased temperatures: decline i...
Chaloub, Ricardo M.; Costa, Rodrigo Mariath V. da; Silva, João; Nassar, Cristina A. G.; Reinert, Fernanda; Széchy, Maria Teresa M.Sargassum is an important primary producer of rocky bottom communities in coastal ecosystems. Like other parts of the planet, benthic populations of S. natans from Ilha Grande Bay (IGB), southeastern Brazil, have been suffering from different forms of natural and anthropogenic disturbances, in particular increasing seawater temperatures. The aim of this study was to understand the effects of temperature on the ...

Mardegan, Sílvia Fernanda; Nardoto, G. B.; Higuchi, Niro; Reinert, Fernanda; Martinelli, Luiz Antônio(Variation in nitrogen use strategies and photosynthetic pathways among vascular epiphytes in the Brazilian Central Amazon). The variation in nitrogen use strategies and photosynthetic pathways among vascular epiphyte families was addressed in a white-sand vegetation in the Brazilian Central Amazon. Foliar nitrogen and carbon concentrations and their isotopic composition (δ15N and δ13C, respectively) were measu...
