This paper presents the description of the three manca stages of the terrestrial isopod Porcelliodilatatus Brandt, 1833 (Porcellionidae). Ovigerous females were collected and kept in the laboratory under controlled conditions (23°C ± 1°C and 14:10 h light:darkness). After birth, mancas (M) were individually reared, and their development was observed. Stages M I, M II, and M III were described based on general characteristics, ommatidia, and appendages. The average development time of each stage was: M I = 18.7 ± 1.5 h (n = 52), M II = 12.7 ± 1.19 days (n = 101), and M III = 12.7 ± 0.45 days (n = 24). Growth was observed using measurements of cephalotorax width. The main characteristics of each stage are presented.

Predicting is very difficult, especially about the future, attributed to Niels Bohr.Abstract As societies realise the importance of maintaining biodiversity and, accordingly, acknowledge the need for monitoring, minimizing and compensating the impacts of socioeconomic activities, including transportation, more scientists will be called to address these societal challenges. Railway Ecology is emerging in this context as a relatively new field to identify and provide solutions to the specific environmental problems associated with the building and operation of railways, particularly their impacts on wildlife. This is an interdisciplinary field that uses and draws methods from other disciplines, ranging from ecology and genetics, to statistics and computer simulations. Here, we summarize the guidelines to address railway-related biodiversity conservation problems as they were identified in the several chapters of this book, and recommend lines for future research.

En América Latina, conocemos bien el enunciado de pertenencia, el lugar intersticial de la voz del inmigrante. Punto de habla —y de narrativa— que conlleva dificultades al momento de superar el complejo proceso de mestizaje étnico y cultural. Al indagar sobre estos aspectos, el presente artículo produce reflexiones sobre la presencia judía en la literatura brasileña.
