Molecular and Genetic Pathogenesis of Lung Cancer: Differences Between Small-Cell and Non-Small-Cell Carcinomas

Abstract

The potential advantage of corporate vigilance to rabbit, Oryctolagus cuniculus, groups was studied in free-ranging rabbits that associated and cohabited basically in male-female ‘consorting’ pairs. Evening observations were conducted of rabbits during the breeding season. Levels of vigilance of an individual rabbit during feeding decreased with proximity to that rabbit's ‘consort’. In contrast, rabbits increased their vigilance in the presence of greater numbers of non-consort rabbits either nearby or over 12 m away. An experiment using stuffed animals as stimulus objects indicated that the presence of a strange rabbit or of a fox increased the proportion of time that rabbits spent vigilant. Non-social factors also influenced vigilance and feeding. In particular, vigilance decreased as the evening proceeded and with higher temperature. For bucks only, it also decreased as the season advanced.
