Resumo: | Spider learning and memory, which attract relatively little attention, are nonetheless interesting objects for an ecologically oriented analysis. A number of representative studies are reviewed showing, in several species of spiders, habituation and sensitization in predatory or defensive behavior; increased efficiency of specific sequences through training, the learning to chose or rejects specific prey items. Spatial memory is taken more in detail, as a special case. It is suggested that spiders have memory processes analogous to the “working” and “reference” memory of mammals. A series of observations about the factors at work during return to the center of the wed in a tropical orb weaver, Argiope argentata, is reported. This spider achieves its orientation through the use of the dragline, discrimination of thread patterns, kinesthetic and gravitational memory, as alternative or integrated strategies. The experimental and naturalistic analysis of past experience effects in spiders has implications for the understanding of learning and memory as adaptive phenomena. |

Apresenta-se um levantamento de estudos representativos mostrando, em diversas espécies de aranhas, a existência de habituação e sensibilidade na caça e na defesa; aperfeiçoamento de seqüência instintivas com o treino, aprendizagem na escolha ou rejeição de presas. Aborda-se mais em detalhes, como estudos de caso, a memória especial em aranhas, que tem aspectos aparentemente animais análogos à memória operacional e à memória de referencia de outros animais. Relata-se o resultado de uma série de observações novas sobre os fatores que, na orbitela Argiope argentata, atuam no retorno ao centro da teia: fio de caminhada, geometria da teia, memória de dicas cinestésicas (memória “idiotética”) e de dicas gravitacionais. O estudo dos efeitos da experiência passada em aranhas, feito dentro das estratégias naturalística e de análise experimental, contribuindo para a compreensão da aprendizagem e da memória enquanto fenômenos adaptativos.Universidade Federal de Santa Catarina1988-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2329610.5007/%xBiotemas; v. 1 n. 1 (1988); 2-272175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/23296/21012Copyright (c) 1988 Cesar Adesinfo:eu-repo/semantics/openAccessAdes, Cesar2012-09-05T14:37:31Zoai:periodicos.ufsc.br:article/23296Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2012-09-05T14:37:31Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |
