Structural and functional responses of benthic invertebrates to imidacloprid in...

Pestana, J. L. T.; Alexander, A. C.; Culp, J. M.; Baird, D. J.; Cessna, A. J.; Soares, A. M. V. M.

Structural and functional responses of a benthic macroinvertebrate assemblage to pulses of the insecticide imidacloprid were assessed in outdoor stream mesocosms. Imidacloprid pulses reduced invertebrate abundance and community diversity in imidacloprid-dosed streams compared to control streams. These results correlated well with effects of imidacloprid on leaf litter decomposition and feeding rates of Pteronar...


Phenotypic variation of Fucus ceranoides, F. spiralis and F. vesiculosus in a t...

Cairrão, E.; Pereira, M. J.; Morgado, F.; Nogueira, A. J. A.; Guilhermino, L.; Soares, A. M. V. M.

Brown algae includes several species of Fucus, reported both in the tidal and intertidal zones of cold and temperate regions. Environmental parameters induce wide biological variability in intertidal algae, manifested by alterations at several levels, and this has lead to the failure of some reports to discriminate between closely related taxa, particularly Fucus species. As the genus Fucus is widely represente...


Endosulfan sulphate interferes with reproduction, embryonic development and sex...

Palma, P.; Palma, V. L.; Fernandes, R. M.; Soares, A. M. V. M.; Barbosa, I. R.

Endosulfan sulphate is the transformation product of endosulfan and it is the most frequent form of surface water contamination with endosulfan. The aim of this study was to evaluate the possible effects promoted by endosulfan sulphate in changes on the life cycle, embryo development and sex differentiation of Daphnia magna. The endpoints used were moulting frequency, fecundity, growth, developmentally abnormal...


Projecto industrial de uma queijaria

Soares, A. M.; Fontinha, C. S.; Guiné, Raquel

No âmbito da disciplina de Seminário de Projecto da Licenciatura em Engenharia das Indústrias Agro-Alimentares, realizou-se este trabalho, do qual se apresenta aqui um pequeno resumo, pretendeu-se fazer um projecto de uma queijaria tradicional semi-mecanizada, que utilize técnicas de fabrico modernas, mas que permita a elaboração de um produto final que se assemelhe ao produto artesanal...


The use of visible and near infrared reflectance spectroscopy to predict beef M...

Andrés, S.; Silva, A.; Soares-Pereira, A.L.; Martins, C.; Bruno-Soares, A.M.; Murray, I.

Visible and near infrared reflectance spectroscopy was used to predict pH at 24 h (pH24) post-mortem, sarcomere length (SL), cooking loss (CL), Warner–Bratzler Shear Force (WBSF) and colour parameters (L*, a*, b*) in beef cattle samples. Samples from M. longissimus thoracis et lumborum from 30 bulls were aged at 4 C for 1, 3, 7 and 14 days and analysed for pH, SL, CL, WBSF and colour. NIRS calibrations for pH2...

A duna consolidada de Oitavos, a Oeste de Cascais, região de Lisboa : a sua dat...

Soares, A. M. Monge; Moniz, Catarina; Cabral, João

A duna consolidada de Oitavos, atribuída ao Quaternário, situa-se junto ao litoral, a oeste de Cascais. Apresenta-se o programa de datações pelo radiocarbono que permitiu a datação dessa duna e discute-se a fiabilidade das datas obtidas. Processaram-se amostras de Helix provenientes não só da duna de Oitavos, mas também da duna consolidada de Magoito, localizada cerca de 16 km para norte e já devidamente dat...

Comparison between two lunar situations on emission and larval transport of dec...

Gonçalves, F.; Ribeiro, R.; Soares, A. M. V. M.

This study compares the rhythms of larval release of the most abundant decapod crustaceans between the New Moon and the First Quarter. Eurelian field surveys were conducted at a small estuary (Mondego river) on the Atlantic coast of Portugal. All taxa showed tidal and lunar rhythm changes in abundance. The larval emission was very strong during nocturnal ebb neap tides at the First Quarter. Export of zoea did n...


Assessing the trophic state of Linhos lake: a first step towards ecological reh...

Pereira, R.; Soares, A. M. V. M.; Ribeiro, R.; Gonçalves, F.

Lack of recognition of the value of wetlands has led to the loss of considerable areas of these ecosystems in the past. Linhos lake (Figueira da Foz, Portugal) is a good example of one of these ecosystems, in which human intervention was responsible for its environmental degradation and led to its precocious terrestrialization. Physico-chemical conditions and zooplankton community structure were studied in Linh...


INTRASPECIFIC VARIATION IN NEUROTOXIC AND MYOTOXIC ACTIVITIES OF Bothrops neuwi...

BORJA-OLIVEIRA,C. R.; SOARES,A. M.; ZAMUNÉR,S. R.; HYSLOP,S.; GIGLIO,J. R.; PRADO-FRANCESCHI,J.; RODRIGUES-SIMIONI,L.

Snake venoms frequently vary in composition. In this work, we compared the neurotoxic and myotoxic activities of 16 lots of Bothrops neuwiedii venoms from different regions of Brazil, using chick biventer cervicis preparations. The neuromuscular blockade varied from 2% to 100% after 120 min incubation with venoms (50 mug/ml). In all cases, this blockade was irreversible and concentration-dependent; at low conce...
