Resumo: | Worker polymorphism in ants has long been a concern of myrmecologists, and given the evolutionary significance of worker size variation, quantification has become a major concern. Due to allometric relationships among boby parts, most studies focus upon worker head dimensions, and repeatable measurements are major sources of experimental error. We present a simple method for obtaining repeatable measurements and for storing measured head capsules, based upon decapitation and flush mounting on microscopic slides, which are used for measurements with microscope ocular micrometers. Using student labor, we have reduced repeated measurement error in 50%. |

Devido as relações alometricas entre partes corporais, a mai oria dos estudos usan as dimensões da cabeça da operaria. Porém, é difícil obter medidas repetidas, sendo uma fonte potencial de erro expe rimental. Apresentamos um método simples para obter medidas repetidas e para manter as cápsulas cefálicas em forma permanente. As cabeças são remo vidas e montadas sobre laminas de microscópio, as quais podem ser medi das com um micrometro ocular. Usando alunos de graduação, o erro de medição cai 50% com esse método.Universidade Federal de Santa Catarina1995-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2274210.5007/%xBiotemas; v. 8 n. 1 (1995); 91-962175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/22742/20725Copyright (c) 1995 Harold G.
