Theoretical Study on the Influence of Iron Mordant in the Optical Properties of...
Candeias, A. Estevão; Costa, C.T.; Carvalho, A.J. Palace; Ramalho, J. P. Prates; Mendes, Paulo J.Geometry optimization of free alizarin, purpurin and luteolin and coordinated Fe(II) complexes was performed at DFT/B3LYP level. TD-DFT spectra were also calculated for free and coordinated alizarin and luteolin. For the Fe(II) complexes several spin multiplicities have been calculated and quintuplet spin structures were found to be the most stable. In the luteolin-Fe(II) complex, the coordination of the chromo...

Allelopathic plants. XVII. Cistus ladanifer L.
Dias, A.S.; Costa, C.T.; Dias, L.S.Cistus ladanifer is a Mediterranean aromatic shrub with a wide array of anatomical, phenological, and physiological characteristics that explains its success as a pioneer species in arid environments. Also, it is very well fitted to cyclic and strong disturbances as those resulting from frequent fires. Therefore, in addition to a general characterization of the species, we address the fire ecology of C. ladanif...
Low courtship song variation in South and Southeastern Brazilian populations of...
COSTA,C. T. A.; KUHN,G. C. S.; SENE,F. M.Drosophila meridionalis is a cactus-breeding species with a wide distribution in South America. Most populations of this species are geographically isolated, what provides a promising scenario for studying evolution. Former studies of this species revealed a remarkable karyotypic variation among its populations. Up to six distinct metaphase chromosomes were described, showing that this species is polymorphic at...
