Twenty-nine behavioural acts were recorded during the 19-week observation period. Young individuals performed tasks inside the nest related to brood care and care for the fungus garden, whereas older individuals performed activities outside the nest such as foraging and activities in the waste chamber. The average longevity (±SD) was 108.21 ± 3.30, 109.15 ± 1.92 and 122.71 ± 1.55 days for large, medium and small workers, respectively. The small-sized workers presented a higher probability of reaching older age than large-and medium-sized workers. This study describes task switching according to age polyethism and the relationship of physical and temporal subcastes.

Two nests were excavated through the opening of trenches and one was cement-moulded to enable a better view of the internal structures. The three nests presented a similar structure, with the depths and number of chambers varying as a function of the loose soil area of the nests. The number of chambers ranged from 1149 to 7864, reaching as deep as 7 m underground. Chamber volume ranged from 0.03 to 51 l. The foraging tunnels extended as far as 70 m from the loose soil region. The nests of this species are the deepest within the genus Atta and have the highest number of chambers.

This work aimed to identify attractive substances, with potential for incorporation in a matrix of granulated baits for grass-cutting ants, among several kinds of sugars and substances used in artificial sweeteners. Experiments were carried out in mature nests of Atta capiguara (Hym.: Formicidae) set in pasture. Studied substances were sucrose, fructose, soluble starch, raffinose, maltose, lactose, sorbose, cellobiose, arabinose, xylose, glucose, galactose, rhamnose, arabinose, melezitose, saccharine and cyclamate (at 5.0% w/v). Later, on maltose, xylose, sucrose, fructose and glucose solutions were included at 5.0%, 7.5%, 10.0% and 20.0% w/v, respectively. Cellulose rectangles were used as vehicle and number of rectangles carried into the colonies was evaluated. Carrying rates were very low with maximum means of 9.6% for lactose and 6.0% for arabinose and cyclamate, at the 5.0% concentration. No differences (P > 0.05) were observed relatively to the control (distilled water). No effects were detected for solution, concentration and for the interaction of these factors. Sugars and artificial sweeteners studied were not attractive to Atta capiguara workers, turning their inclusion as attractants in toxic ant baits not viable.

Il s'agit de faire réfléchir, observer et interpréter le processus d'enseignement/apprentissage, en assumant la place de l'apprenant, à travers une expérience de contact avec une langue inconnue ou pas apprise dans un contexte formel. Cette activité se divise en 4 moments: dans un premier temps, le professeur en formation est confronté au défi d'écouter et comprendre un poème n Portugais sur le pouvoir des mots ; dans un deuxième temps, il s'agit de faire comprendre le même poème à l'aide du texte écrit ; dans un troisième temps, il s'agit de donner des aides lexicales pour faciliter une compréhension plus détaillée ; dans un dernier temps, il s'agit de préciser quelques points de grammaire portugaise afin de faciliter le processus de compréhension de la langue.

This project aimed at the construction of a collaborative teacher education context for learning and transformation of experiences, views and practices in language education, and involved teachers, teacher educators and researchers. Based on a single case study, the analysis tries to disclose the teacher’s discursive displacements as hints of professional transformation while she reinterprets the learning taking place in the collaborative education process. The signs of change are visible in the way she constructs meanings regarding her professional identity, re-identifies her mission as a language teacher and reconsiders her professional identity. Finally, we reflect upon how collaborative teacher education scenarios may foster teachers’ personal professional learning and renewed self-images.

A análise dos dados de um estudo de caso, no âmbito de um programa de formação contínua, evidencia que o DP é fruto da intersecção da acção individual com a acção colectiva em ambientes com características facilitadoras de DP. Os resultados indicam também que a formação em contexto permite iniciar um trabalho de DP porque cria condições de auto/hetero/eco e co-formação que incluem um potencial de aprendizagem profissional transformativa, conducente a novos modos de ser e estar em educação.
