Differential memory persistence of odor mixture and components in newborn rabbits: competition between the whole and its parts
2014
Interacting with the mother during the daily nursing, newborn rabbits experience her body odour cues. In particular, the mammary pheromone (MP) contained in rabbit milk triggers the typical behaviour which helps to localize and seize the nipples. It also promotes the very rapid appetitive learning of simple or complex stimuli (odorants or mixtures) through associative conditioning. We previously showed that 24h after MP-induced conditioning to odorants A (ethyl isobutyrate) or B (ethyl maltol), newborn rabbits perceive the AB mixture in a weak configural way, i.e. they perceive the odour of the AB configuration in addition to the odours of the elements. Moreover, after conditioning to the m…
Évaluation neuro-éthologique du comportement alimentaire olfacto-guidé du lapin nouveau-né
2012
Le document qui a justifié la délivrance du diplôme est en cours de traitement par la bibliothèque de l'établissement de soutenance.; L'olfaction est une sensorialité essentielle aux mammifères, dès les stades les plus précoces du développement. Ainsi, chez le lapin européen (Oryctolagus cuniculus), les nouveau-nés interagissent avec la mère et s'orientent vers ses tétines suite à la perception de signaux odorants appris périnatalement, ou d'au-moins un signal à l'action prédisposée, la phéromone mammaire (PM; molécule contenue dans le lait de lapine). La PM est très fortement réactogène au cours des 15 premiers jours postnatals, période d'alimentation lactée exclusive. Elle déclenche alors…
Biometric characterisation and taxonomic considerations of european rabbit Oryctolagus cuniculus (Linnaeus 1758) in Sicily (Italy)
2014
In Sicilian Mediterranean ecosystems the European rabbit Oryctolagus cuniculus is a keystone species, very important for popular small game species and for ecological reasons. However, its spread across the island seems to have decreased and fragmented in recent times, but until now no accurate population management has been carried out due to the lack of ethological, ecological and taxonomic knowledge. A biometric analysis of European rabbit specimens from Sicily to widen current taxonomic knowledge was performed. In this paper, 7 body variables and 23 cranial variables of 166 and 120 individuals, respectively, were examined. Thereafter, the results were compared with biometric data from o…
