(Instituto de Ciências da Saúde/ Universidade Federal da Bahia, 2004)
Influenza virus sialidase develops an essential activity on cellular glycoproteins, then permitting the dissemination of the
virus infections by preventing virus-virus self aggregation and virus-cell rebinding. Two purified ...
Colonização por macroinvertebrados bentônicos em substrato artificial e natural em um riacho da serra de Itatinga, São Paulo, Brasil
(Sociedade Brasileira de Zoologia, 2004-06-01)
Substratos artificial e natural foram comparados quanto ao processo de colonização por macroinvertebrados. No 1º, 3º, 7º, 13º, 21º, 31º e 42º dias de amostragem a riqueza e a abundância dos macroinvertebrados foi analisada. ...
Use flexibility of perch types by the branch-camouflaged Common Potoo (Nyctibius griseus): Why this bird may occasionally dare to perch on artificial substrates
(2018-03-01)
Animal species gain protection against visually oriented predators when they choose a suitable substrate that maximizes camouflaging. The choice of appropriate substrate may be particularly important during the brooding ...
