Copper-driven avoidance and mortality in temperate and tropicaltadpoles
Araújo, Cristiano V.M.; Shinn, Cândida; Moreira-Santos, Matilde; Lopes, Isabel; Espíndola, Evaldo L. G.; Ribeiro, R.Amphibians have experienced an accentuated population decline in the whole world due to many factors,one of them being anthropogenic contamination. The present study aimed to assess the potential effect ofcopper, as a worldwide and reference contaminant, on the immediate decline of exposed population dueto avoidance and mortality responses in tadpoles of three species of amphibians across climatic zones:a South...
Copper-driven avoidance and mortality in temperate and tropical tadpoles

Going with the Flow: Detection of Drift in Response to Hypo-Saline Stress by th...
Araujo, Cristiano V. M.; Romero-Romero, Sonia; Lourençato, Lucio F.; Moreno-Garrido, Ignacio; Blasco, Julián; Gretz, Michael R.; Moreira-Santos, MatildeAvoidance response is a well-known mechanism for escaping environmental stress. For organisms with reduced active movement, such as benthic microalgae, drifting could be a specifically selected mean of avoiding less favorable environments. To test this hypothesis, a system was developed to assess if hypo-saline stress triggers drift in the estuarine benthic diatom Cylindrotheca closterium. Concurrently, the eff...
Micorriza arbuscular em plantações de Eucalyptus cloeziana F. Muell no litoral ...
Araújo,Cristiano V.M.; Alves,Lander de J.; Santos,Osvaldo M.; Alves,Jacyr M.As micorrizas arbusculares são de longa data conhecidas e exploradas devido à importância ecológica e aos efeitos no crescimento e na nutrição das plantas. Eucalyptus cloeziana F. Muell, particularmente nas áreas em estudo, apresenta comportamento diferenciado quando comparado com outras espécies de eucaliptos, instalando-se em sítios de solos pobres e textura arenosa, com crescimento reduzido, dificuldades par...
