(Universidade Federal de São Carlos, 2015-11-30)
The complexity and interaction of environmental problems have directed the landscape structure studies, which emphasizes broad spatial scales related to ecological effects of spatial patterns of the ecosystems. Changes in ...
Avaliação ecotoxicológica de um novo potencial formicida: análises in vitro e in vivo
(Universidade Federal de São Carlos, 2018-06-22)
The use of toxic bait represents an important tool when dealing with important agriculture and silviculture plagues, where hesperidin flavonoid complexation with magnesium(II) generates a compound (Mg(hesp)) with high ...
Biodiversidade de Selenastraceae (Sphaeropleales, Chlorophyceae) : características morfológicas e sequenciamento dos marcadores moleculares 18S rDNA, rbcL e ITS como base taxonômica tradicional
(Universidade Federal de São Carlos, 2016-02-04)
The phylogeny of the family Selenastraceae was investigated by light microscopy, molecular analysis of 18S rDNA, rbcL, ITS1-5.8S-ITS2 and ITS-2 markers. Several morphological features traditionally used for identification ...
