Growth and accumulation of carotenoids and nitrogen compounds in Gracilaria dom...

Effects of the interaction of irradiance and nutrient levels on growth and contents of photosynthetic pigments, carotenoids and proteins in Gracilaria domingensis (Kütz.) Sonder ex Dickie (Gracilariales, Rhodophyta) were investigated experimentally. Nutrient availability provided by dilutions of the nutrient solution of von Stosch (25 and 50%, which corresponded to nitrate concentrations of 125 and 250 μmo...

Contagion effects of the subprime crisis in the European NYSE Euronext markets

This paper presents three tests of contagion of theUS subprime crisis to the European stock markets of the NYSE Euronext group. Copula models are used to analyse dependence structures between the US and the other stock markets in the sample, in the pre-crisis and in the subprime crisis periods. The first test assesses the existence of contagion on the relevant stock markets’ indices, the second checks the homog...

Contagion effects of the US subprime crisis in developed countries

This study assesses whether capital markets of developed countries reflect the effects of financial contagion from the US subprime crisis and, in such case, if the intensity of contagion differs across countries. Adopting a definition of contagion that relates the phenomenon to an increase of cross-market linkages following a shock, copula models are used to analyse how the connections between the US and each m...

Avaliação de extratos de macroalgas bênticas do litoral catarinense utilizando ...

Foram coletadas amostras de algas marinhas de 19 espécies (sendo 4 pertencentes ao filo Chlorophyta, 5 ao filo Phaeophyta e 10 ao filo Rhodophyta) em dois locais do litoral catarinense. Os extratos etanólicos foram submetidos ao teste de letalidade para larvas de Artemia salina com objetivo de realizar uma triagem das espécies. Dos 26 extratos testados, 25 apresentaram toxicidade significativa em pelo menos uma...

Morphology and reproduction of Predaea feldmannii Børgesen (Nemastomataceae, Rh...

The coast of Espirito Santo State is located in a biogeographic transition zone presenting high diversity. A renewed interest in this region occurred in the 1990s, resulting in various new records and new species descriptions added to the Brazilian marine flora. The study of the infralitoral of this region is just beginning, and a detailed exploration with use of Scuba diving is revealing a flora containing man...
