Evaluation of the joint effect of glyphosate and dimethoate using a small-scale...
Santos, MJG; Morgado, R; Ferreira, NGC; Soares, AMVM; Loureiro, SIn the present work a small-scale terrestrial ecosystem (STEM) containing a soil collected from an agricultural field in Central Portugal was used to evaluate the effects of the combination of the herbicide glyphosate and the insecticide dimethoate. Earthworms (Eisenia andrei), isopods (Porcellionides pruinosus), turnip seeds (Brassica rapa), and bait-lamina strips were placed in the STEM. The results showed th...
Chrysothrix flavovirens, Lepraria elobata, and Ochrolechia arborea new to Portugal
Rodrigues, SA; Tonsberg, T; Terron-Alfonso, A; Soares, AMVMChrysothrix flavovirens, Lepraria elobata, and Ochrolechia arborea are reported as new to Portugal, based on surveys carried out in pine forests along the Portuguese coast. Data on the distribution, secondary products and ecology of the species are presented.
Lecanora sorediomarginata, a new epiphytic lichen species discovered along the ...
Rodrigues, SA; Terron-Alfonso, A; Elix, JA; Perez-Ortega, S; Tonsberg, T; Fernandez-Salegui, AB; Soares, AMVMLecanora sorediomarginata Rodrigues, Terron & Elix sp. nov., described as new to science from Portugal, is characterized morphologically by a crustose whitish-grey to greenish thallus developing soralia from small, marginal warts and chemically by the presence of 3,5-dichloro-2'-O-methylnorstenosporic acid [major], 3,5-dichloro-2'-O-methylanziaic acid [minor], 3,5-dichloro-2'-O-methylnordivaricatic acid [minor]...
Developmental Toxicity of Endocrine Disrupters Bisphenol A and Vinclozolin in a...
Lemos, MFL; van Gestel, CAM; Soares, AMVMStudies of the effects of endocrine-disrupting compounds (EDCs) on invertebrates are still largely underrepresented. This work aims to fill this gap by assessing the effects of bisphenol A (BPA) and vinclozolin (Vz) on the terrestrial isopod Porcellio scaber (common rough woodlouse). Male adult and sexually undifferentiated juvenile woodlice were exposed to the toxicants. Effects on molting regime and growth we...
Public attitudes towards the restoration and management of Lake Vela (Central P...
Pereira, R; Soares, AMVM; Ribeiro, R; Goncalves, FLake Vela local inhabitants' and visitors' environmental attitudes and opinions about ecological conditions of the area and future management strategies to be implemented were investigated. The facilities required and the proposal to promote tourism activities, to enhance economic development, have revealed public illiteracy about ecosystems functioning and carrying capacity. This lack of scientific knowledge w...
Histological evaluation of the exposure to 3,4-dichloroaniline in the estuarine...
Sardo, AM; Azeiteiro, UM; Pereira, L; Morgado, F; Soares, AMVMThis work presents an experimental approach to test Mesopodopsis slabberi as a potential indicator of pollution. The toxic effects of 3,4-dichloroaniline (DCA) on the histology of this estuarine mysid were studied. After an acclimation period of two days, the mysids were exposed to different sublethal 3,4-DCA concentrations (0.10, 0.30, 0.50, 0.90, 1.00, 1.10, 1.20, 1.30 and 1.40 mg/L), for a period of 48 h.
